Description

  The present invention relates to a seat cable holding device for holding a cable routed over both a seat cushion and a seat back of a vehicle seat having at least a sliding function and a reclining function.

  2. Description of the Related Art Conventionally, a vehicle seat having a slide function and a reclining function is provided with various mechanism members and electric parts such as a side airbag system including these slide mechanisms and a reclining mechanism, and these mechanism members are structured with an inner wire and an outer wire structure. The cable wire is used for connection, and electrical components are electrically connected using a wire harness.

  And when routing cables such as the above-mentioned cable wires and wire harnesses over the seat cushion and the seat back, the cable once led out from the lower surface of the seat cushion can be routed from the lower end of the seat back to the inside thereof. However, the tilting of the seat back caused by the seat slide and reclining operation, especially the seat back, causes the cable exposed outside the seat to sag and deteriorates its appearance. It has been proposed to absorb cable slack by providing a cable (see Patent Document 1).

JP 2000-142191 A (see paragraphs 0005 to 0011 and FIG. 2)

  However, in the thing of the above-mentioned patent document 1, the cable exposed to the exterior of the sheet remains exposed, and the deterioration of the appearance is not improved, and in addition to removing slack, in order to prevent the cable from hanging down There is a problem that a large number of clips for fixing the cable to the seat cushion are required, and the number of parts increases, resulting in an increase in cost.

  An object of the present invention is to prevent the appearance of a cable from being deteriorated by covering an exposed portion of the cable with a covering cover, and to prevent the cable from sagging and drooping with an inexpensive configuration.

  In order to achieve the above-described object, a seat cable holding device according to the present invention includes a seat cable for holding a cable routed over both a seat cushion and a seat back of a vehicle seat having at least a sliding function and a reclining function. In the holding device, the cable is routed along the inside of the seat back and along the lower surface of the seat cushion, and is led out from the lower end of the seat back to the lower surface of the seat cushion. It is arranged in an approximately S-shape from the rear to the front, one end is fixed to the lower surface of the seat cushion, and is exposed to the outside from the lower end of the seat back so as to allow slack in the S-shaped portion of the cable. A covering cover for covering the exposed portion of the cable at the other end It is characterized in Rukoto (claim 1).

  In addition, the present invention may further include support means for supporting an end of the S-shaped portion of the cable on the lower surface of the seat cushion (claim 2).

  According to the first aspect of the present invention, the cable is once led out to the outside from the lower end of the seat back, and is arranged in an approximately S shape from the rear to the front on the lower surface of the seat cushion, and one end portion is the lower surface of the seat cushion. The exposed portion of the cable is covered by the other end portion of the covering cover fixed to the cable so that the exposed portion of the cable exposed to the outside from the lower end of the seat back is allowed to sag at the S-shaped portion of the cable. The cable can be blindfolded to prevent the appearance from the outside from being deteriorated, and the cable can be bent while being bent into an S-shape to absorb slack in the S-shaped part. The cable can be prevented from sagging downward, and even if the space under the seat cushion is very narrow, the cable can sag and sag with an inexpensive configuration. Both it is possible to prevent.

  According to the second aspect of the present invention, since the end of the S-shaped portion of the cable is supported by the support means on the lower surface of the seat cushion in addition to the covering cover, it is possible to absorb the slack in the S-shaped portion of the cable. Only by arranging one supporting means in addition to the covering cover, a large number of clips are not required as in the prior art, and the cable can be more reliably prevented from drooping downward with an inexpensive configuration.

  An embodiment in which a cable holding device for a seat according to the present invention is applied to a cable for unlocking a sliding motion of a rear seat will be described in detail with reference to FIGS. Note that front and rear and left and right in the present embodiment mean front and rear and left and right as viewed in a seated state on the seat.

  1 and 2 show a rear seat 1 mounted on an automobile having a luggage compartment at the rear of the passenger compartment, and can be slid in the front-rear direction by a slide mechanism having a pair of left and right slide rails installed on the passenger compartment floor F. , A seat back 3 in which a seat back frame is tiltably coupled to the seat cushion frame by a reclining mechanism, and a headrest 4 attached to the seat back 3.

  The slide mechanism is in a state where the lock mechanism is unlocked by the unlocking operation of the slide handle 6 provided at the front lower side of the seat cushion 2 and the seat 1 can slide in the front-rear direction. When the unlocking operation is stopped, the locking mechanism is activated, the locking member is locked to the slide rail, and the seat 1 is held so as not to slide. Here, as shown in FIGS. 1 and 3, the slide handle 6 includes a concave-shaped operation portion 6 a, an extended portion 6 b that extends outward at both ends, and a connecting portion 6 c that connects the extended portions on both sides. The ends of the extending portions 6b on both sides are rotatably supported by the seat cushion frame, and the central operating portion 6a is attached downward by a biasing means such as a spring (not shown). It is energized.

  The slide mechanism and the lock mechanism will be briefly described. By pulling the operation portion 6a at the center of the slide handle 6 upward against the urging force, the lock portion of the lock mechanism attached to the seat cushion frame becomes a spring force. As a result, the seat cushion 2 is released from the locked state with the slide rail on the passenger compartment floor side, and the seat cushion 2 is slidable. On the other hand, when the pulling up of the operation portion 6a of the slide handle 6 is stopped, the operation portion 6a of the slide handle 6 is pulled back to the lower position by the biasing force of the biasing means, and accordingly, the lock portion of the lock mechanism is moved downward by the spring force. The seat cushion 2 is pulled back and locked to the locking portion on the slide rail side, so that the seat cushion 2 cannot slide.

  By the way, as shown in FIGS. 1 to 3, the seat 1 is locked at the upper right portion of the rear surface of the seat back 3 so that the seat 1 can be slid in an unlocking operation state in order to expand the cargo compartment. An operation unit 8 for canceling is provided. As shown in FIGS. 4 and 5, the operation portion 8 includes a concave base portion 8a attached to the seat back frame 3a and an upper end portion accommodated in an opening 8b of the base portion 8a. And an operating lever 8e whose lower end is urged forward by a winding spring 8d that is rotatably supported on both left and right inner walls of 8a and is wound around a pin 8c. In FIG. 4, 8f is a C-ring for retaining the pin 8c that engages with the pin 8c.

  Further, as shown in FIG. 6, a cable 9 configured by inserting a wire 9b longer than the outer tube 9a is provided in the outer tube 9a, and two cables 9b provided on the outer tube 9a of the cable 9 are provided. The clips 9c are respectively routed inside the seat back 3 and below the seat cushion 2 and locked to the upper end portion of the seat back frame 3a and the front end portion of the seat cushion frame 2a, and the outer tube 9a is fixed to the seat 1. It is held in the state. Furthermore, the both ends of the outer tube 9a are provided with locking portions 9a1 having depressions, and both ends of the wire 9b are provided with locking portions 9b1 having a T-shape.

  Then, as shown in FIG. 5, the recess of the locking portion 9a1 on one end side of the outer tube 9a of the cable 9 is locked and fixed to the upper side wall of the base portion 8a of the operation portion 8, and one end portion of the wire 9b is opened. 8b is inserted into the base 8a, the T-shaped locking portion 9b1 at one end of the wire 9b is locked in the locking groove 8g at the upper front end of the operating lever 8e, and one end of the wire 9b is the upper end of the operating lever 8e. It is connected to the part.

  As shown in FIG. 3, such a cable 9 is routed up and down in the seat back 3, and once led out from the lower end of the seat back 3 to the front and rear along the lower surface of the seat cushion 2. As shown in FIGS. 1, 3, and 7, the cable 9 is curved and arranged on the lower surface side of the seat cushion 2 so as to form an S shape.

  At this time, the exposed portion R of the cable 9 led out from the lower end of the seat back 3 shown in FIGS. 1 and 2 is, for example, a cloth covering whose one end is fixed to the lower right end of the seat back 3 shown in FIG. Covered by a cover 11. The other end portion of the covering cover 11 is disposed so as to go around from the lower end portion of the rear surface of the seat back 3 to the lower surface side of the seat cushion 2 as shown in FIGS. 1, 2, and 7. An urging member 12 made of rubber or the like is joined to the other end of 11, and the urging member 12 is fixed to the lower surface of the seat cushion 2, whereby the curved S-shaped cable 9 is interposed via the covering cover 11. An urging force that pulls the one end side forward is applied, and the protrusion of the exposed portion R of the cable 9 to the rear is suppressed, and a deterioration in appearance due to the exposure of the cable 9 is prevented.

  As shown in FIGS. 1 and 7, one end of the support means 13 made of a biasing material such as rubber is fixed to the seat cushion 2, and the other end of the support means 13 is used for other than the curved S-shape of the cable 9. The ends of the cable 9 that are curved at the lower surface of the seat cushion 2 are supported by the ends of the S-shaped ends of the cable 9 in the different directions indicated by the dashed arrows in FIG. As a result, the central portion of the S-shape of the cable 9 is supported in a state in which it can move substantially in the front-rear direction, as indicated by the solid line arrow in FIG. This prevents the cable 9 from hanging down on the lower surface side of the seat cushion 2 even if the seat back 3 is tilted backward, and at the same time, even if the cable 9 sags due to the seat back 3 being tilted backward, The slack of the cable 9 is absorbed in the center of the S-shaped portion where the cable 9 is curvedly arranged. At this time, the portion (exposed portion R) covered by the covering cover 11 of the cable 9 is subjected to a forward biasing force by the biasing member 12, so that the cable 9 is not moved even if the seat back 3 is tilted backward. The enveloping part does not protrude backward.

  As shown in FIGS. 1 and 3, a guide member 14 having a curved guide surface is fixed to the front end portion of the seat cushion frame 2a near the lock mechanism, and the outer tube 9a of the cable 9 is attached to the guide member 14. The other end of the wire 9b is disposed so that the other end of the wire 9b exposed from the outer tube 9a is aligned with the curved upper guide surface of the guide member 14. Is changed from a forward-facing state to a downward-facing state, the T-shaped locking portion 9b1 at the other end of the wire 9b is locked at the connecting portion 6c of the slide handle 6, and the other end of the wire 9b is at the slide handle 6. It is connected to.

  Then, when the seat 1 is slid forward to expand the cargo compartment, as shown by the arrow in FIG. 5, when the lower end portion of the operation lever 8e of the operation portion 8 is lifted against the spring 8d, The lower end portion of the operation lever 8e rotates as indicated by a two-dot chain line in FIG. 5, whereby the wire 9b of the cable 9 is pulled relative to the fixed outer tube 9a. 6 is lifted against the spring force, and the operation portion 6a is unlocked and unlocked, and the seat 1 is slid to a desired position to make the cargo compartment a desired wide area. It can be expanded. At this time, although the cable 9 is somewhat slack due to the pulling operation, the slack is absorbed by the S-shaped arrangement of the cable 9 on the lower surface of the seat cushion 2.

  If the lifting of the lower end portion of the operation lever 8e of the operation unit 8 is stopped, the operation lever 8e returns to the original position by the urging force of the spring 8c, and thereby the wire 9b of the cable 9 is pulled back to the original state. As a result, the slide handle 6 is pulled back by the spring force, and the lock portion of the lock mechanism is again engaged with the engagement portion on the slide rail side, and the seat 1 is fixed in a non-slidable state.

  Therefore, according to the above-described embodiment, the cable 9 is once led out to the outside from the lower end of the seat back 3, and is arranged in an approximately S shape from the rear to the front on the lower surface of the seat cushion 2, and one end is seated. The cable exposed to the outside from the lower end of the seat back 3 so as to allow sagging at the S-shaped portion of the cable 9 by the other end of the covering cover 11 fixed to the lower surface of the cushion 2 via the biasing member 12 Since the exposed portion R of the cable 9 is covered, the exposed portion R of the cable 9 can be blinded to prevent the appearance from the outside from being deteriorated, and the cable 9 is arranged while being bent in an S shape. The slack can be absorbed by the portion, and the slack downward of the cable 9 can be suppressed by the covering by the covering cover 11, and between the seat cushion 2 and the passenger compartment floor F Even if to have no space, it is possible to prevent both the sag and the cable slack inexpensive configuration.

  Moreover, since the end of the S-shaped portion of the cable 9 is supported by the support means 13 on the lower surface of the seat cushion 2 in addition to the covering cover 11, the S-shaped portion of the cable 9 can of course absorb slack. By simply arranging the support means 13 in addition to the covering cover 11, it is possible to more reliably prevent the cable 9 from drooping downward with an inexpensive configuration without requiring many clips as in the prior art. .

  Further, a curved guide surface where the other end portion of the wire 9b exposed from the outer tube 9a of the cable 9 is slidably contacted with the other end of the cable 9 connected to the slide handle 6 of the wire 9b is operated. Since the guide member 14 is provided and the other end of the wire 9b is placed along the guide surface of the guide member 14 so that the direction thereof is changed downward, the operation lever 8e is operated to operate the wire 9b of the cable 9. When the wire 9b is pulled relative to the outer tube 9a, the other end portion of the wire 9b smoothly slides on the curved guide surface of the guide member 11, and the other end portion of the wire 9b is bent by stress. This can be prevented and damage to the wire 9b due to stress can be prevented beforehand.

  It should be noted that the present invention is not limited to the above-described embodiment, and various modifications other than those described above can be made without departing from the spirit thereof. For example, the cover 11 can be extended forward in the law. Thus, if the cable 9 is covered up to almost the center of the S-shape, the cable 9 can be prevented from drooping only by the covering cover 11 without providing the support means 13, and the cost can be reduced by reducing the number of parts. Can be reduced.

  Further, in the above-described embodiment, the example in which the support means 13 having the urging force is provided is shown, but the support means 13 may be formed by a member that supports the cable 9 from below so as to be movable. Furthermore, the covering cover 11 is not limited to the above-described cloth, and in short, it is desirable that the covering cover 11 be formed of a flexible material so as to be easily handled. Further, the urging means 12 and the supporting means 13 are not limited to the above-described rubber, and may be constituted by a spring or other elastic member.

  In the above-described embodiment, the example in which the present invention is applied to the cable 9 for unlocking the sliding motion of the rear seat 1 has been described. However, for example, as shown in FIG. The present invention can also be applied to a reclining cable 16 connected to the reclining adjustment handle 15 and the reclining mechanism and routed on the lower surface of the seat cushion 2, and further, a wiring harness 17 for connecting other electrical devices (FIG. 3). Of course, the present invention can also be applied to a cable routed on the lower surface of the seat cushion 2 (see FIG. 6).

  Moreover, although the example applied to the rear seat 1 was shown in the above-described embodiment, the scope of application of the present invention is not limited to the rear seat 1 and can be applied to a vehicle seat other than the rear seat. It is.
