Thus, the folded ends are the rear portions 35b and 39b. The rear portions 35b and 39b of the left protective band 35 and the right protective band 39 are sewn and fixed at the center of the rear portion of the belt cloth 10 (the part of the hips of the pants wearer). Sewing is performed by directly sewing the rear portions 35b and 39b of the left protective band 35 and the right protective band 39 to the belt cloth 10 and pressing the rear portions 35b and 39b with the cloth piece 40 to the belt cloth 10 together with the cloth piece 40. You can sew.

  The left protective band 35 and the right protective band 39 have been described as being separated from each other, but may be a continuous structure. In other words, by joining the ends of a long, long band with elasticity and elasticity at the center of the band, folded portions are formed on both sides, and the center of the band is belted with both ends of the band. You may sew and fix to the position of the center of the rear part of the cloth 10.

  A left connection surface fastener 33 and a right connection surface fastener 37 are sewn and attached to the folded portion side front portions 35a and 39a of the left protection band 35 and the right protection band 39. The left connection surface fastener 33 and the right connection surface fastener 37 are detachably coupled to the left abdominal surface fastener 32 and the right abdominal surface fastener 36 by extending the left protection band 35 and the right protection band 39 against elasticity. . The left abdominal surface fastener 32 and the right abdominal surface fastener 36 can adjust the elastic strength (tensile strength) of the left protective band 35 and the right protective band 39 by changing the connecting position of the left connecting surface fastener 33 and the right connecting surface fastener 37. Thus, it is formed long in the width direction.

  The trousers 1 with the back pain protection band have the above-described configuration, and are worn in the same manner as normal trousers. As shown in FIG. The left connecting hook-and-loop fastener 33 provided at the front part of the left protective band 35 is detachably connected to the left abdominal hook-and-loop fastener 32 of the belt portion 11 by being extended. Similarly, the right protective band 39 is passed through the belt loop 21, the right protective band 39 is extended against elasticity, and the right connection surface fastener 37 provided at the front of the right protective band 39 is attached to the right side of the belt portion 11. The abdomen surface fastener 36 is detachably connected. Since the left abdomen surface fastener 32 and the right abdomen surface fastener 36 are formed long in the width direction, the attachment positions of the left connection surface fastener 33 and the right connection surface fastener 37 are changed, and the left protection is made according to the wearer's body shape. The elastic force of the band 35 and the right protective band 39 can be adjusted.

The trousers 1 with the back pain protection band can play a role of a column in which the abdominal pressure rises and the abdominal cavity is hard by the back pain protection band 31 tightening the abdomen, can enhance the protection of the lumbar spine, and can reduce the burden on the waist. You can reinforce your abs and maintain the correct posture. The trousers 1 with the lumbago protection band are connected to the pair of left abdomen surface fasteners 32 and the right abdomen surface fasteners 36 with respect to the left connection surface fastener 33 and the right connection surface fastener 37 of the pair of left protection band 35 and right protection band 39. If you change the connecting position in the length direction, you can adjust the tightening of the abdominal pressure according to the length of the abdomen, and change the reinforcing position in the vertical direction of the waist by changing the connecting position in the vertical direction can do.

  In the said embodiment, as shown to FIG.3, 4, the low back pain protection belt | band | zone 31 is sewn and attached to the position (part of a trouser wearer's hipbone) in the center of the rear part of the belt cloth 10. FIG. However, as shown in FIGS. 11 and 12, the lower back pain protection band 51 may be detachably attached to the position of the center of the rear part of the belt cloth 10 (the part of the hip bone of the pants wearer) by the attaching / detaching means. The lower back pain protective band 51 includes a left protective band 55 having a left connection surface fastener 53 provided at the front portion and a right protective band 59 having a stretch property provided with a right connection surface fastener 57 provided at a front portion. Become.

  The left protective band 55 and the right protective band 59 are formed by folding a long band having elasticity and elasticity such as a rubber band at the center and overlapping both ends, and the folded portion side is the front portions 55a and 59a. Thus, the folded ends are the rear portions 55b and 59b. The rear portions 55 b and 59 b of the left protective band 55 and the right protective band 59 are sewn to the cloth piece 40 so as to be pressed by the cloth piece 40. A tape snap 62 having a pair of male buttons 61 and 61 is sewn and attached to the cloth piece 40. A tape snap 64 having a pair of female buttons 63 and 63 is sewn and attached to a position in the center of the rear portion of the belt cloth 10 (part of the hip bone of the pants wearer).

  The low back pain protective band 51 including the left protective band 55 and the right protective band 59 includes a pair of male buttons 61 and 61 of a tape snap 62 attached to the cloth piece 40 and a pair of tape snaps 64 attached to the belt cloth 10. The trouser 1 is attached to the belt cloth 10 by being detachably connected to the female buttons 63 and 63. The back pain protection band 51 has been described as having a separated configuration including the left protection band 55 and the right protection band 59, but may be a continuous configuration. That is, by joining the ends of a long, long band with elasticity and elasticity at the center of the band, folded portions are formed on both sides, and the center of the band and both ends of the band are sewn. The belt cloth 10 is detachably attached to the center of the rear part.

  As shown in FIG. 13, the left protective band 55 and the right protective band 59 are formed to have a length such that the front part overlaps when attached to the trousers 1. That is, one of the left protective band 55 and the right protective band 59 is formed to have substantially the same length as the protective bands 35 and 39, and the other of the left protective band 55 and the right protective band 59 is from the protective bands 35 and 39. It is formed long. In the present embodiment, the left protective band 55 is formed longer than the right protective band 59. The front lower surface of the left protective band 55 overlaps the front upper surface of the right protective band 59. A right connecting surface fastener 66 is attached to the front upper surface of the right protective band 59 by sewing, and a left connecting surface fastener 67 is attached to the front lower surface of the left protective band 55 by sewing. Therefore, when the left protective band 55 and the right protective band 59 are attached to the trousers 1 and stretched against the elasticity of the left protective band 55 and the right protective band 59, and the front portions 55a and 59a are overlapped, Since the right connecting surface fastener 66 and the left connecting surface fastener 67 are connected, it can be wound so as to press the entire circumference of the abdomen. The right connecting surface fastener 66 and the left connecting surface fastener 67 adjust the overlapping length of the front portions 55a and 59a of the left protective band 55 and the right protective band 59, so that the elastic strength of the left protective band 55 and the right protective band 59 ( It is formed long in the width direction so that the tensile strength) can be adjusted.

  The left protective band 55 and the right protective band 59 are detachably connected to the left abdominal surface fastener 32 and the right abdominal surface fastener 36 on the lower surfaces of the left protective band 55 and the right protective band 59, similarly to the left protective band 35 and the right protective band 39. The connection surface fastener 53 and the right connection surface fastener 57 are sewn and attached. The left connecting surface fastener 53 and the right connecting surface fastener 57 extend the left protective band 55 and the right protective band 59 against elasticity, and are detachably connected to the left abdominal surface fastener 32 and the right abdominal surface fastener 36. .

  The trousers 1 with a back pain protection band have the above-described configuration, and are worn in the same manner as normal trousers. As shown in FIG. 13, the left protection band 55 and the right protection band 59 are stretched against elasticity to protect the left The left connecting surface fastener 67 provided at the front portion of the band 55 is detachably connected to the right connecting surface fastener 66 provided at the front portion of the right protective band 59. By changing the connection position of the left protective band 55 and the right protective band 59, the elastic force of the left protective band 55 and the right protective band 59 can be adjusted according to the wearer's body shape. The left connecting surface fastener 53 of the left protective band 55 is detachably connected to the left abdominal surface fastener 32 of the belt portion 11, and the right connecting surface fastener 57 of the right protective band 59 is connected to the right abdominal surface fastener 36 of the belt portion 11. The left protective band 55 and the right protective band 59 can be positioned by being detachably connected.

  In the trousers 1 with the back pain protection belt, the back pain protection belt 51 tightens the entire circumference of the abdomen, so that the abdominal pressure increases and the abdominal cavity acts as a hard column, enhancing the protection of the lumbar spine and reducing the burden on the waist. Can reinforce the abdominal muscles and maintain the correct posture. The trousers 1 with the back pain protection belt can change the connection position of the left connection surface fastener 67 and the right connection surface fastener 66 of the pair of the left protection band 55 and the right protection band 59, and change the connection position in the length direction. The tightening level of abdominal pressure can be adjusted according to the length of the body.

  The male buttons 61 and 61 and the female buttons 63 and 63 constitute an attaching / detaching means (snap button) 60 for the lumbago protection band 51. The male buttons 61, 61 and the female buttons 63, 63 are tape snaps 62, 64, and are formed thin, so that the waist does not feel uncomfortable when the trouser 1 is worn. The male buttons 61 and 61 and the female buttons 63 and 63 are arranged at a predetermined interval in a direction substantially perpendicular to the longitudinal direction (the direction of pulling) of the low back pain protection band 51. Since the male buttons 61 and 61 and the female buttons 63 and 63 are pulled substantially equally by the left protective band 55 and the right protective band 59 from both sides when connected, the connection is not easily released. The attaching / detaching means is not limited to the snap button, and may be a hook-and-loop fastener.

  In the above embodiment, the right protective band 59 is formed with the same length as the protective bands 35 and 39, and the left protective band 55 is formed longer than the right protective band 59, but as shown in FIG. Similarly to the left protective band 55, the right protective band 59 may be formed longer than the protective bands 35 and 39.

  When the right protective band 59 is attached to the trouser 1, the right protective band 59 can be stretched against elasticity to connect the right connection surface fastener 57 of the right protective band 59 to the left abdominal surface fastener 32 (see FIG. 14B). When the left protective band 55 is stretched against elasticity and the front portions 55a and 59a are overlapped, the right connecting surface fastener 66 and the left connecting surface fastener 67 are connected, so that the entire circumference of the abdomen is wound. Can do.

  The trousers 1 with the back pain protection band are not pulled when the wearer is in an upright posture, the back pain protection bands 31 and 51 are located around the waist of the wearer, and the stretchable fabric 15 and the covering cloth 16 are , Hardly extended. As shown in FIG. 9, when the wearer of the trousers 1 with the back pain protection band takes a squatting posture, the upper edges 15 a and 16 a are stitched to the belt cloth 10, and the lower edges 15 b and 16 b are stitched to the back body 3. Since the stretchable fabric 15 and the covering fabric 16 that are sewn are appropriately stretched, the belt portion 11 of the trousers is not pulled downward and the back pain protection belts 31 and 51 are not displaced from the waist portion. . Since the stretchable fabric 15 follows the stretch of the skin of the waist when the posture changes, high exercise performance can be ensured.

  The lumbar region referred to here indicates the vicinity of a portion protruding forward in the pelvis of the wearer of the trouser 1 (a portion generally called “upper anterior iliac spine”). The back pain protective bands 31 and 51 can be most effective in preventing the back pain from occurring by attaching them at positions corresponding to the waist. In order to bring out the effect, in the present application, the crotch of the trouser 1 (part from the lower end of the belt cloth 10 to the upper end of the crotch part) is formed so as to be shallow so that the belt cloth 10 naturally comes to the waist position when the trousers are worn. ing. Since the belt cloth 10 is located at the waist, the back pain protection bands 31 and 51 attached to the belt cloth 10 are also located at the waist, and the effect of protecting the back pain can be enhanced.

  In normal trousers, when the inseam is formed shallowly, the waist of the trousers is pulled downward further when a squatting posture or the like is taken. However, in the trousers 1 with the back pain protection band, the waist stretchable part 20 is provided at the waist, so that the positions of the back pain protection bands 31 and 51 are not shifted from the waist part. That is, when the squatting posture or the like is taken, the waist stretchable portion 20 is appropriately extended as shown in FIG. 10, so that the back pain protection bands 31 and 51 are always arranged at positions corresponding to the waist without being displaced from the waist, thereby protecting the back pain. It is possible to maintain a state in which the bands 31 and 51 are wound around the entire circumference of the waist. Since the back pain protection bands 31 and 51 can be tightened only at the position corresponding to the waist without shifting up and down from this position, a stable back pain prevention effect can be obtained.

  When the trousers 1 with the back pain protection band are not provided with the stretchable fabric 15 and the covering cloth 16, when the wearer of the trousers 1 with the back pain protection band takes a squatting posture as shown in FIG. The back body 3 directly acts on the belt portion 11, and the belt portion 11 is pulled downward, so that the positions of the back pain protection bands 31 and 51 are shifted from the waist portion. As described above, the trousers 1 with the back pain protection band include the stretchable fabric 15 and the covering cloth 16, so that the back pain protection bands 31 and 51 are not shifted and can always be maintained at a necessary position.

  When the wearer of the trousers 1 with the back pain protection belt sits down on the chair as shown in FIG. 10, the stretchable fabric 15 and the covering fabric 16 are appropriately extended, so that the belt portion 11 of the trousers is pulled down and lowered. The back pain protection bands 31, 51 are not displaced from the lower back. On the other hand, when the trousers 1 with the back pain protection band are not provided with the stretchable fabric 15 and the covering cloth 16, the wearer of the trousers 1 with the back pain protection band sits on the chair as shown in FIG. The back body 3 directly acts on the belt portion 11 and the belt portion 11 is pulled downward, so that the positions of the low back pain protection bands 31 and 51 are shifted from the waist portion. As described above, the trousers 1 with the back pain protection band include the stretchable fabric 15 and the covering cloth 16, so that the back pain protection bands 31 and 51 are not shifted and can always be maintained at a necessary position.

  The trousers 1 with the lumbago protection band are not conspicuous because the stretchable fabric 15 and the covering cloth 16 are provided at the waist of the wearer, and the stretchable fabric 15 and the covering cloth 16 are accompanied by the movement of the wearer. Since it stretches appropriately, it is easy for the wearer to exercise and the back pain protection bands 31, 51 are difficult to slip, and further, pilling and snacking on the stretchable fabric 15 does not occur, so that it can withstand long-time wear. It has become.

  The trousers 1 with the lumbago protective band have a covering cloth 16 that is appropriately expanded and contracted when the worker bends (bends forward), such as a posture in which the wearer (worker) is squatting or a standing knee. Is not exposed, the appearance is prevented from deteriorating, and the stretchable fabric 15 and the covering fabric 16 expand and contract, so that the belt portion 11 of the trousers 1 with the back pain protection band is pressed against the abdomen of the operator. It can be reduced, and back pain can be further reduced. That is, as shown in FIG. 10, the trousers 1 with the back pain protection belt can prevent “pull” and “slip down” of the rear belt portion 11 b on the rear side of the belt portion 11 in a sitting posture or the like. Abdominal pressure in the front belt portion 11a on the front side can be avoided.

  Thereby, when the wearer of the trousers 1 with the back pain protection band takes a posture of squatting or the like and the skin of the waist or the buttocks stretches, the stretchable fabric 15 appropriately stretches following the stretch of the skin, and the back pain protection band It is possible to avoid a feeling of discomfort (such as pressure in the abdomen) occurring in the wearer of the attached trousers 1. That is, in the case of normal light work trousers not provided with the stretchable fabric 15, as shown in FIG. 18, the wearer moves from an upright posture (FIG. 18 (a)) to a standing knee (FIG. 18 (b)). When taking a sitting position (FIG. 18C) and a squatting posture (FIG. 18D), the trousers cannot follow the stretch of the skin, and the rear belt portion 11b of the trousers is downward as shown in FIGS. The back is open, the back is opened, the shirt protrudes, and the abdomen of the wearer is pressed by the front belt portion 11a. Furthermore, the wearer's spine is also pressed by the abdominal pressure, which may cause back pain. However, in the trousers 1 with the back pain protection band, as shown in FIGS. 9 and 10, the stretchable fabric 15 is stretched following the growth of the skin, so the position of the belt portion 11 does not change, the abdomen is not compressed, and back pain occurs. It does not occur.

  More specifically, when the wearer of the trousers 1 with the back pain protection band is in a squatting position (FIG. 18 (d)), the trousers 1 with the back pain protection band from the waist to the buttocks, the waist to the buttocks (from top to bottom). The amount of skin stretching increases as it goes to (the skin stretch rate is larger in the lower groin area (groove area) than in the upper groin area). Therefore, in FIG. 7, as described above, the upper side (between the upper edge 15a of the stretchable fabric 15 and the covering cloth / elastic cloth joining portion 18A) and the lower side (the covering cloth / elastic cloth joining portion 18A) The stretchable fabric 15 stretches greatly between the covering fabric and the stretchable fabric joining portion 18B), so that the waist portion generated when the wearer of the trousers 1 with the back pain protection belt is crouched or the like The discomfort in the buttocks and the pressure in the abdomen can be reduced, and the occurrence of back pain can be eliminated.

  Furthermore, even if the wearer (operator) of the trousers 1 with the back pain protection belt bends the waist, the skin of the operator's waist and the like extends in the vertical direction, and the stretchable fabric 15 extends according to the elongation of the skin. The heel-like covering cloth 16 is also stretched in the same manner, so that the stretchable fabric 15 is not exposed, and the stretch of the stretchable fabric 15 and the covering cloth 16 causes the back side of the belt portion 11 of the trousers 1 with the back pain protection band. Since almost no gap is formed between the rear belt portion 11b and the waist of the operator, the appearance is prevented from deteriorating.

  More specifically, in the conventional trousers, unlike the jumpsuit, the upper garment is separated and only the lower garment is formed, so that the wearer of the trousers bends (bends forward) the waist as shown in FIGS. Then, the rear belt portion 11b of the trousers slides downward, and the above-described gap is formed, so that the waist portion of the wearer is exposed. In some cases, the shirt (hem) placed in the pants goes out of the pants and becomes unsightly. By exposing the lower back part, the body cools down, causing adverse effects such as making it easier to catch a cold.

  In contrast, in the trousers 1 with the back pain protection band, as shown in FIGS. 9 and 10, even if the pants wearer flexes (bends forward) the waist, the stretchable fabric 15 extends according to the elongation of the skin. The waist is not exposed and the waist is kept warm. In addition, even if the wearer of the trousers 1 with the back pain protection band is squatting, the shirts such as the upper garment will not collapse from the hem (at the belt) of the trousers 1 with the back pain protection band, and the underwear will not be exposed. Is avoided, the shirt that protrudes from the trousers 1 with the back pain protection belt is prevented from being caught by the protrusion, and the occurrence of a situation where the shirt is caught in the machine is avoided.

  Moreover, even if the wearer of the trousers 1 with the back pain protection band is squatting, it is avoided that sparks such as filth, debris or welding work enter the trousers 1 with the back pain protection band from the hem of the trousers 1 with the back pain protection band. The risk of injury is avoided. Moreover, since there is almost no loss of wear, there is almost no need to correct the loss of wear and it is possible to cope with emergencies. Furthermore, since the elastic fabric 15 is provided, even if the trousers 1 with the back pain protection band stick to the skin of the wearer due to sweat, the operation of squatting does not become difficult.

  Trousers with lumbago protection belts are light work such as office work in the company (for example, work exclusively for desk work, supermarket clerk work, home appliance mass sales clerk work, waiter work, cook work, pachinko shop work It is suitable for light work trousers (slack, trousers, pants so-called normal trousers) worn by employees and the like during the work of hall staff, the work of cleaning companies, etc.

  Moreover, as shown in FIG. 15, a pair of rear pockets 25 and 26 are provided in the trouser body 1a at the left and right heel portions. The rear pockets 25 and 26 are, for example, bead pockets, and are located below the left and right ends of the stretchable fabric 15 and the covering fabric 16. In the elastic fabric 15 and the covering cloth 16 described above, in the left-right direction of the trouser body 1a, the positions of the left ends 15c, 16c substantially coincide with the center of the left rear pocket 25, and the positions of the right ends 15d, 16d are the right rear pocket. It is desirable to substantially coincide with the center of 26. The reason why the stretchable fabric 15 and the covering cloth 16 are set between the centers of the rear pockets 25 and 26 is that the rear pockets 25 and 26 themselves are generally determined in the trousers and are suitable as a standard for limiting the range. is there.

  Generally, the light work pants have an upper end below the human waist, and the rear pockets 25 and 26 are further provided with an opening slightly below the middle hip. The hip circumference at that point is about 25% wider than that of the waist. Therefore, the stretchable fabric 15 and the covering cloth 16 are considerably narrow as shown in FIG. 15 if both ends coincide with the centers of the pockets 25 and 26.

  The attached document 1 shown in FIG. 19 confirms that it is desirable that the positions of the left and right ends of the stretchable fabric 15 and the covering fabric 16 substantially coincide with the centers of the left rear pocket 25 and the right rear pocket 26. It is a graph which shows the result of the experiment conducted for this purpose. The subject in the experiment has a height of 169 cm, a waist of 80 cm, wears an L-size trouser (for waist 80-85 cm), and the interval between the pocket centers is 27.3 cm.

  In the experiment, when the subject changed his posture from an upright posture (FIG. 18A) to a squatting posture (see FIG. 18D and the figure in the graph) or a sitting posture (FIG. 18C). The amount of skin elongation in the back of the waist is measured. In FIG. 19, the center corresponds to the position of the spine (back body center), and the numbers on the horizontal axis represent the distance in the left-right direction from the spine position to the measurement position. The vertical axis represents the elongation of the skin at that position. Since the distance between the centers of the left and right rear pockets 25 and 26 is 27.3 cm, the center position of the left and right rear pockets 25 and 26 is located at a point about 13.7 cm away from the center of the back body.

  From the figure, for example, when taking a crouching posture, skin elongation of 1.7 cm occurs at the center of the back body, but at a position about 8.1 cm away from the center, the elongation is about half and is about 13.5 cm apart. It is understood that the elongation is zero at the part. Similarly, the skin stretch of 1.2 cm occurs at the center when taking a sitting posture, but the stretch is about half at a position about 8.1 cm away from the center, and stretches at a position about 13.5 cm away from the center. Is understood to be zero.

  As described above, by making the length of the stretchable fabric 15 coincide with the distance of 27.3 cm between the centers of the left and right rear pockets 25, 26, the end of the stretchable fabric 15 is separated from the back body center by about 13.7 cm to the left and right. The stretchable fabric 15 is provided in the part (range) where the skin stretch occurs and the stretched fabric 15 is not provided in the part where the skin stretch does not occur. This stretchable fabric 15 can eliminate this problem. Therefore, the trousers 1 with the back pain protective band have a technical feature that the use of the useless stretchable fabric 15 can be avoided.

  The arrangement of the rear pockets 25 and 26 is common and is generally determined in normal trousers. From the above experiment, it has been found that the point at which the skin stretch is zero is almost in the center of the rear pockets 25 and 26. That is, the trousers 1 with the back pain protection belt can be seated with the stretchable fabric 15 having the minimum length by setting the length of the stretchable fabric 15 to 27.3 cm between the centers of the left and right rear pockets 25 and 26. As a result, the rear belt portion 11b can be prevented from being pulled or slipped down, and abdominal pressure in the front belt portion 11a can be avoided.

  Here, the measurement result of the clothing pressure in the wearer's abdomen and waist when the trouser body 1a is worn is shown. For measurement of clothing pressure, the wearer puts on the trouser main body 1a (pants) or the conventional trousers (pants), installs the belt through the belt loop 21 on the outer periphery of the belt portion 11, and the trouser main body 1a does not fall by the belt. The pressure sensor was installed between the belt portion 11 and the belt with the waist appropriately tightened.

  As shown in FIG. 16, the position of the pressure sensor is as follows: left lower scapula P1, lower left flank P2, lower left nipple P3, midline P4, right lower nipple P5, right lower heel P6, right Seven locations of P7 immediately below the scapula were used. The wearer takes the upright posture (standing posture) shown in FIG. 18 (a), the standing knee posture shown in FIG. 18 (b), and the chair sitting posture shown in FIG. 18 (c). The pressure between the part 11 was measured. Note that measurement of pressure in an upright posture in the trouser body 1a is omitted.

  The wearers are A and B. The former is a man with a physique of 172cm tall, 78kg weight, and 88cm waist. B is a physique male with a height of 169 cm, a weight of 72.5 kg, and a waist of 90 cm. FIG. 17 shows the measurement result of pressure by the pressure sensor. The values shown in FIG. 17 (unit: kPa) are average values. This average value is an average value for a measurement time of 10 seconds, and more specifically, an average value of pressures measured 11 times every second for 10 seconds.

  FIG. 17A shows pressure measurement results (seven measurement results) when a conventional ordinary pant is worn and the upright posture, the standing knee posture, and the chair sitting posture are taken. FIG. 17B shows the pressure measurement results (seven measurement results) when the upper is put on the trouser body 1a and the standing knee posture and the chair sitting posture are taken. FIG. 17 (c) shows the measurement results of pressure (measurement results at seven locations) when the conventional ordinary pants are worn by the trousers and take the upright posture, the standing knee posture, and the chair sitting posture. FIG. 17D shows pressure measurement results (seven measurement results) when the trouser body 1a is worn by the trousers and the kneeling posture and the chair-sitting posture are taken.

  As is clear from FIG. 17, the pressure (clothing pressure) detected by the pressure sensor is larger when the standing knee posture and the chair sitting posture are taken than when the posture is upright. In addition, although there are individual differences between the former and the second, comparing the clothing pressure of the normal pants and the clothing pressure of the trouser body 1a, the clothing pressure applied to the front (abdominal side) of the wearer, especially when taking the standing knee posture. However, it is reduced by the trouser main body 1a. In addition, even when taking a chair sitting posture, although not as much as a standing knee posture, the clothing pressure applied to the wearer's front surface (abdominal side) is reduced by the trouser body 1a.

  Furthermore, although the allowable pressure is generally 3.92 kPa, the maximum value is 2.83 kPa in the trouser main body 1a, and any clothing pressure is lower than the allowable value. Thereby, in the trouser body 1a, in addition to the above-described effects such as prevention of the occurrence of low back pain, the wearer suppresses physiological phenomena such as an increase in blood pressure, an increase in pulse, sweating, fatigue, headache, and vomiting. be able to.

  Attached document 2 shown in FIG. 20 is a graph of FIGS. 17 (c) and 17 (d). In this graph, points P3, P4, and P5 indicate directly under the left nipple, the midline portion, and immediately under the right nipple, and the bar graph indicates the clothing pressure at each point. These points P3, P4 and P5 are points located on the front side of the position where the stretchable fabric 15 is provided on the back body in the body of the subject.

  The clothing pressure at these points rises when the chair-sitting posture is taken, but the degree of rise becomes smaller by providing the stretchable fabric 15 than when the fabric is not provided. I understand. Points P1 and P7 indicate directly below the left scapula and right scapula, and these points P1 and P7 are located on the back side of the subject's body where the stretchable fabric 15 is provided on the back body. is there.

  It can be seen that the clothing pressure at these points decreases when the chair-sitting posture is taken, compared to the upright posture, but the degree of reduction becomes smaller by providing an elastic fabric than when the fabric is not provided. From this, the trouser body 1a does not increase the clothing pressure on the front side of the body (that is, does not compress the abdomen) and does not reduce the clothing pressure on the back side of the body (ie, does not compress the abdomen) in the chair sitting posture. It can be seen that there is no pulling or sliding down).

  As described above, the trousers 1 with the back pain protection belt are the rear belt part 11b on the rear side of the trousers such as the belt part 11 and the like of the operator when the trousers 1 for the light work (normal trousers) are in a squatting position. In order to prevent the formation of a gap in the waist and reduce the abdominal pressure in the front belt part 11a on the front side of the trousers, an expansion / contraction part is installed at an interval where the skin of the back body extends, Part)). The trousers 1 with a back pain protection belt are provided with an expansion / contraction part in order to prevent pulling of the rear belt part 11b in a sitting posture or the like and avoid abdominal pressure in the front belt part 11a. Since the stretchable part is provided in the necessary part of the waist where the skin stretches, the width is minimized, and the original appearance as a light work trouser can be maintained.

  As described above, when the trousers 1 with the lumbago protective band are in the squatting position or the sitting position, the skin elongation becomes zero at a predetermined distance from the spine position of the waist. And in the place away from the above (13.5 cm or more in FIG. 19), the skin itself shrinks. Accordingly, when the stretchable fabric 15 is provided in such a place, unnecessary bulging occurs in the pants in a squatting posture or the like. Such unnecessary bulging not only wastes the fabric, but also causes a risk of being caught by an external protrusion or the like located on the side of the waist. Therefore, it is desirable to consider that the width of the stretchable fabric 15 matches the width between the centers of the pockets 25 and 26 from these points.

  The present invention can be used for trousers with a back pain protection band in which a waist protection band is fixedly attached to the trouser body.
