Description

  The present invention relates to a seat cover, and more particularly, to a vehicle seat, and a seat that prevents a displacement from occurring between the seat portion of the vehicle seat due to movement of the occupant during sitting, during sitting, or when getting off the vehicle. Regarding the cover.

  Generally, a seat cover is attached to a vehicle seat for the purpose of enhancing the interior decoration effect of the vehicle interior or preventing the vehicle seat itself from becoming dirty or damaged. However, this kind of seat cover is displaced mainly in the front direction of the vehicle with respect to the seating portion of the vehicle seat with movement of the occupant sitting, during sitting, or getting off, and impairs the stability of the seating. Includes problems.

  There has been proposed a seat cover that is configured to prevent the displacement of the seat cover caused by the movement of the occupant during sitting, during sitting, or when getting off, and to improve the sitting stability (for example, , See Patent Document 1).

  The seat cover described in Patent Document 1 is provided with a cylindrical stopper insertion portion in the cover main body, and the seat cushion ( After inserting it into the gap between the seating part) and the seat back (backrest part) so that it is exposed to the rear side, it is expanded by inserting a stopper such as an umbrella into the stopper insertion part. By making the stopper insertion part interfere with the rear end of the seat cushion (seat part) and the lower end of the seat back (back part), the vehicle seat is prevented from being displaced mainly in the forward direction with respect to the seat part. It is configured to be able to.

Japanese Patent Laid-Open No. 2001-231662

  However, the seat cover having the above-described structure requires not only a stopper such as an umbrella, but also the prepared stopper must be inserted into the stopper insertion portion in a narrow space in the passenger compartment, so that it is troublesome to install the seat cover. . In addition, when an umbrella is applied as a stopper, an extra effort to insert and remove the umbrella is required when getting on and off the vehicle during rain, so that the trouble of attaching the seat cover becomes even more complicated. Furthermore, since the stopper insertion / removal to / from the stopper insertion portion is performed in the rear space of the vehicle seat, it cannot be used for the rear seat where there is no space on the rear side of the vehicle seat, and the usable seat is only the front seat. Limited to In addition, in the case of a vehicle having a rear seat, the stopper insertion portion expanded by a stopper such as an umbrella is exposed in the space under the rear seat occupant's feet, so that the effective space under the rear seat occupant's feet is reduced accordingly, and the rear portion It has problems such as making the seat occupant feel uncomfortable.

  The present invention has been made in view of the above circumstances, and can prevent the vehicle seat from being displaced in the forward direction with respect to the seating portion of the vehicle seat, facilitates attachment to the vehicle seat, and The seat can be used in either the front or rear seats to ease restrictions on use and avoid the narrowing of the effective space under the rear seat seater's feet, thereby eliminating the uncomfortable feeling of the rear seat seater. The purpose is to provide a cover.

  In order to achieve the above object, a seat cover according to the present invention comprises a seat surface cover portion disposed on a seat portion of a seat having a seat portion and a back portion, and a back cover portion attached to the back portion. In the seat cover including at least the seat surface cover portion, a locking body is provided on the seat surface cover portion, and the locking body penetrates through the gap between the seating portion and the backrest portion. It is characterized in that the posture can be changed between an allowable posture and a slip-off preventing posture that is locked to the seating portion and the backrest portion after passing through the gap to prevent the gap from being removed from the gap.

  According to the seat cover having the above-described configuration, when the posture of the locking body is changed to the penetration-permissible posture, a part can be passed through the gap between the seating portion and the backrest portion, and when the posture is converted to the slip-off prevention posture, the seating portion Since it can be locked to the backrest and prevented from coming out of the gap, the posture is changed to a permissible posture and partly penetrated into the gap between the seating portion and the backrest, and then converted to a posture that prevents slippage. Then, even if an external force that causes the vehicle seat to be displaced in the forward direction with respect to the seating portion of the vehicle seat acts on the seat surface cover portion, the reaction force generated by the locking body being locked to the seating portion and the backrest portion Thus, it is possible to reliably prevent the seat surface cover portion from being displaced. In addition, since a stopper such as an umbrella is not required, and therefore the stopper need not be inserted or removed, the vehicle seat can be simply operated by passing a part of the locking body through the gap between the seating portion and the backrest portion. Can be easily attached to. Furthermore, since it becomes unnecessary to insert and remove the stopper in the rear space of the vehicle seat, it can be used for a rear seat in which no space exists on the rear side of the vehicle seat. That is, the use restriction can be relaxed by making it possible to use the front and rear seats.

  The locking body of the seat cover according to the present invention comprises a belt-like main body provided on the seat cover portion and a thin locking portion provided at the tip of the main body, and the short locking portion of the thin locking portion. About half of the hand direction overlaps the front end of the belt-shaped main body to form the gap penetration allowing posture, and the thin locking portion is orthogonal to or substantially orthogonal to the main body at the front end of the main body. It is desirable to configure so as to form the above-mentioned prevention posture by deforming into a T shape.

  According to this, since the locking body is composed of the band-shaped main body portion and the thin locking portion provided at the tip of the main body portion, about half of the thin locking portion in the short direction is provided on the band-shaped main body portion. Even if the gap penetration allowing posture is formed so as to overlap the tip portion, the thickness of the gap penetration allowing posture can be kept thin. For this reason, it is possible to smoothly penetrate the gap between the seating portion and the backrest portion. In addition, the posture conversion from the gap penetration allowable posture to the slip prevention posture is performed by the downward bending of the belt-like main body portion at the front end side of the belt-shaped main body portion immediately after the locking portion of the gap penetration allowable posture passes through the gap between the seating portion and the backrest portion. And the moment generated in the locking portion due to the bending. Therefore, it is possible to reliably prevent the seat surface cover portion from being displaced by locking the locking portion to the seating portion and the backrest portion. Further, in a state where the locking portion is locked to the seating portion and the backrest portion, the locking body is slightly moved in the rearward direction of the vehicle, and about half of the thin locking portion is moved to the front end portion of the belt-shaped main body portion. After being converted into a clearance penetration allowable posture by overlapping, the latching body can be detached from the clearance by pulling the seat cover portion in the front direction of the vehicle. Moreover, even in a vehicle having a rear seat, the thin locking portion will be exposed in the space under the rear seat seat occupant, so that the effective space under the rear seat seat occupant foot is prevented from being narrowed, The discomfort of the rear seat occupant can be eliminated.

  In the seat cover according to the present invention, the locking portion of the locking body is formed in a bag shape, and a plate material is accommodated therein.

  According to this, since the rigidity of the locking portion is enhanced by the plate material, it is possible to smoothly penetrate the gap between the seating portion and the backrest portion. Further, the locking force of the locking body at the time of forming the slip-off prevention posture is increased, so that it is possible to improve the slip-prevention action and the seat cover displacement prevention action. Further, since the locking portion becomes heavy corresponding to the mass of the plate material, the downward direction of the belt-like main body portion that occurs immediately after the locking portion in the gap penetration allowing posture passes through the gap between the seating portion and the backrest portion. The bending is instantaneously performed, and the automatic posture change from the clearance penetration allowable posture to the slip-off prevention posture is quickly and reliably performed.

  In the seat cover according to the present invention, it is desirable to provide an opening for inserting / removing the plate material in the engaging portion configured in the bag shape.

  According to this, if a board | plate material is extracted from the opening for board | plate material insertion / extraction, rigidity will lose | disappear and it will become easy to deform | transform. Therefore, if the seat cover is pulled in the forward direction of the vehicle after removing the plate material in the posture to prevent it from coming off, the locking portion interferes with the seating portion and the backrest portion, and can be separated from the gap between them. Since it deforms into a form, it is easy to remove the locking body. Moreover, even if it is a board | plate material which has water absorption and becomes soft by water absorption and becomes non-reusable, since this can be extracted and wash | cleaned, a board | plate material can be reused.

  The seat cover which concerns on this invention may attach the main-body part of the said latching body to the said seat surface cover part so that attachment or detachment is possible by a hook-and-loop fastener.

  According to this, it becomes possible to perform exchange and washing of the seat cover and exchange and washing of the locking body separately. Moreover, since the latching body can be removed from the seat cover portion of the seat cover and the plate material can be removed from the latching portion and washed, the plate material has an adverse effect on other laundry or the inner surface of the laundry tub in the laundry tub. Can be avoided.

  The seat cover according to the present invention can prevent the vehicle seat from being displaced in the forward direction with respect to the seating portion of the vehicle seat, and can be easily attached to the vehicle seat, and can be attached to any seat in the front and rear portions. The use of the rear seat seater can be relaxed by making it possible to use it, and the effective space under the rear seat seater's feet can be avoided from being narrowed, thereby eliminating the uncomfortable feeling of the rear seat seater.

  1 to 4, the seat cover S is connected to the seat surface cover portion 5 disposed on the seat portion 2 of the vehicle seat 4 having the seat portion 2 and the backrest portion 3, and the seat surface cover portion 5. A backrest cover portion 6 mounted on the front surface of the backrest portion 3 and a headrest cover portion 8 provided so as to cover the headrest 7 on the upper side of the backrest portion 3, and the backrest cover portion 6 in the seat surface cover portion 5 A locking body 10 is provided by the sewing means 9 in the center in the width direction of the back surface in the vicinity of the boundary Z.

  The seat cover portion 5, the backrest cover portion 6, and the headrest cover portion 8 of the seat cover S are composed of a surface material Sa and a lining material Sb (see FIGS. 3 and 4) made of a woven fabric mainly made of a chemical fiber such as a polyester fiber and the like. A thin cushion material (not shown) made of polyurethane foam disposed between the two, and the peripheral edge thereof is appropriately sewn.

  The locking body 10 is composed of a strip-shaped main body portion 11 and a thin locking portion 12 provided at the tip of the main body portion 11, and these are constituted by a series of fabrics. That is, a strip-like fabric A having a width W of about 10 cm and an overall length L of about 26 cm shown in FIG. 5A is prepared, and the longitudinal center B of the fabric A is folded in half as shown in FIG. After superimposing the upper base D on the base C, the base C and the upper base D are sewn perpendicularly to the longitudinal direction at a location where l is about 6 cm away from the bent central portion B in the longitudinal direction. Next, with reference to the sewing E line, as shown in FIG. 5C, the base C is bent downward by about 90 degrees, the upper base D is bent upward by about 90 degrees, and then one end portion in the width direction is bent. By sewing F in the vertical direction, the band-shaped main body 11 having a width W of about 10 cm and a length L1 of about 7 cm, and a width W of about 10 cm and a height H of about 6 cm at the tip of the main body 11 are thick. A locking body 10 including a thin and bag-shaped locking portion 12 having a small thickness t is produced. Then, a rigid plate member 14 is accommodated in the latching portion 12 configured in a bag shape from an opening 13 for inserting / removing a plate member provided at one end in the width direction.

  As shown in FIGS. 2 and 3, the front end side of the belt-like main body 11 in the locking body 10 shown in FIG. 5 (c) is sewn on the back surface in the vicinity of the boundary Z with the back cover 6 in the seat cover 5. Combined by the landing means 9. Thereby, on the back surface of the seat surface cover portion 5 in the vicinity of the boundary Z with the backrest cover portion 6, the thin bag-like locking portion 12 is orthogonal to the main body portion 11 at the front end of the main body portion 11. A locking body 10 that is deformed into a T-shape and has a dropout prevention posture X is provided.

  In the above-described configuration, first, as shown in FIG. 3, the locking portion 12 of the locking body 10 forming the slip-off preventing posture X is pressed in the direction of the arrow f with the sewing E as a base point. As shown in FIG. 2, the gap penetration allowable posture Y is formed (posture change) by overlapping approximately half of the locking portion 12 in the short side direction on the distal end portion of the main body portion 11. Next, as shown in FIG. 6A, the locking portion 12 and the front end portion of the main body portion 11 are inserted into the gap 16 between the upper surface of the rear end portion of the seating portion 2 and the lower end surface of the backrest portion 3. Then, the insertion is further continued, and as shown in FIG. 6 (b), the locking portion 12 and the tip end portion of the main body portion 11 are penetrated from the gap 16 to the rear side of the seating portion 2 and the backrest portion 3. Expose.

  Here, the distal end side of the main body portion 11 is bent downward as indicated by a two-dot chain line, and the locking portion 12 is indicated by a two-dot chain line in cooperation with a moment generated in the locking portion 12 due to this bending. By being substantially orthogonal to the main body 11, the posture conversion from the gap penetration allowable posture Y indicated by the solid line to the drop prevention posture X indicated by the two-dot chain line is automatically and quickly performed. Then, when the vicinity of the boundary Z between the seating surface cover portion 5 and the backrest cover portion 6 in the seat cover S is slightly pulled in the direction of the arrow f1, the locking portion 12 becomes the seating portion 2 as shown in FIG. 1 and FIG. And the backrest 3 is locked. Therefore, even if an external force that causes the vehicle seat 4 to be displaced in the forward direction of the vehicle acts on the seat cover portion 5, the locking portion 12 is locked to the seating portion 2 and the backrest portion 3. The position force of the seat surface cover portion 5 can be reliably prevented by the reaction force generated by the presence of the seat surface.

  The seat cover S according to the present invention does not require a stopper such as an umbrella, unlike the seat cover described in Patent Document 1, and therefore does not require the insertion and removal of the stopper. Therefore, the seat portion 2 and the backrest portion 3 It can be easily attached to the vehicle seat 4 only by a simple operation of penetrating the front end side of the locking body 10 into the gap 16 therebetween. Furthermore, since it becomes unnecessary to insert and remove the stopper in the rear space of the vehicle seat 4, it can be used for a rear seat (not shown) in which no space exists on the rear side of the vehicle seat 4. That is, the use restriction can be relaxed by making it possible to use the front and rear seats.

  Since the locking body 10 includes a strip-shaped main body portion 11 and a thin locking portion 12 provided at the tip of the main body portion 11, approximately half of the thin locking portion 12 in the short direction is formed in the strip-shaped main body portion 11. Even if the clearance penetration allowable posture Y is formed so as to overlap with the tip of this, the thickness of the clearance penetration allowable posture Y can be kept thin. For this reason, it is possible to smoothly penetrate the gap 16 between the seating portion 2 and the backrest portion 3. In a state where the locking portion 12 is locked to the seating portion 2 and the backrest portion 3, the locking body 10 is slightly moved in the rearward direction of the vehicle so that about half of the thin locking portion 12 is strip-shaped main body portion. After being converted into the clearance penetration allowable posture Y by being overlapped with the tip end portion of 11, the locking body 10 can be detached from the clearance 16 by pulling the seat surface cover portion 5 in the front direction of the vehicle. Even in a vehicle having a rear seat, the thin locking portion 12 is exposed in the space under the rear seat occupant's feet, so that the effective space under the rear seat occupant's feet is avoided from being narrowed. It is possible to eliminate the uncomfortable feeling of the rear seat occupant.

  Since the locking portion 12 of the locking body 10 is formed in a bag shape and the hard plate material 14 is accommodated therein, the rigidity of the locking portion 12 is enhanced by the plate material 14. Therefore, it is possible to smoothly penetrate the gap 16 between the seating portion 2 and the backrest portion 3. Further, the locking force of the locking portion 12 at the time of forming the slip-off prevention posture X is increased, so that it is possible to improve the slip-prevention action and the seat cover displacement prevention action. Furthermore, since the latching portion 12 becomes heavy corresponding to the mass of the plate member 14, a belt-like shape generated immediately after the latching portion 12 in the clearance penetration allowing posture Y penetrates the gap 16 between the seating portion 2 and the backrest portion 3. The downward deflection of the front end of the main body 11 is instantaneously performed, and automatic posture conversion from the clearance penetration allowable posture Y to the slip-off prevention posture X is performed quickly and reliably.

  Since the opening 12 for inserting / removing the plate material is provided in the locking portion 12 configured in the bag shape, when the plate member 14 is extracted from the opening 13 for inserting / removing the plate material, the rigidity of the engaging portion 12 is lost. It becomes easy to deform. Therefore, when the seat cover 5 is pulled in the front direction of the vehicle after the plate member 14 is pulled out in the slip-off prevention posture X, the locking portion 12 interferes with the seating portion 2 and the backrest portion 3, and the gap between them. Since the shape is deformed so that it can be detached from 16, it is easy to remove the locking portion 12. Moreover, even if it is the board | plate material 14 which has water absorption and becomes soft by water absorption and becomes non-reusable, since this can be extracted and wash | cleaned, the board | plate material 14 can be reused.

  On the other hand, as shown in FIG. 7, the base end portion of the body portion 11 of the locking body 10 is covered with a seat surface cover 17 by a surface fastener 17 comprising a surface fastener 17a on the body portion side and a surface fastener 17b on the seat surface cover portion side. You may attach the latching body 10 to the lower surface of the rear-end part of the part 5 so that attachment or detachment is possible. With the seat cover S configured as described above, the seat cover can be replaced and cleaned, and the locking member 10 can be replaced and cleaned separately. Further, since the latching body 10 can be removed from the seat cover 5 of the seat cover S and the plate member 14 can be removed from the latching portion 12 and washed, the plate member 14 interferes with other laundry in the washing tub. Thus, it is possible to avoid adverse effects such as damaging other laundry, or the plate material 14 rubbing and damaging the inner surface of the washing tub.

  In the above-described embodiment, the seat cover S including the seat cover portion 5, the backrest cover portion 6 and the headrest cover portion 8 has been described, but the seat cover S including only the seat cover portion 5 may be used. Good. Moreover, although the description has been given with the configuration in which one locking body 10 is provided in the center portion in the width direction of the seat surface cover portion 5, a plurality of locking bodies 10 are provided separately in the width direction of the seat surface cover portion 5. May be. By configuring in this way, it is possible to directly cope with not only the central portion in the width direction of the seat surface cover portion 5 but also the external force acting on both ends in the width direction and the vicinity thereof. It is also possible to reliably prevent the positional deviation between the vicinity thereof and both ends in the width direction of the seat surface cover portion 5 and the vicinity thereof.

  Moreover, in the said embodiment, even if the external force which carries out position shift to the front direction of a vehicle with respect to the seat part 2 of the vehicle seat 4 acts on the seat surface cover part 5, the position shift of the seat surface cover part 5 can be prevented. However, in actuality, in addition to the above-described external force that shifts the position in the front direction of the vehicle, the external force in the width direction of the vehicle or a composite direction in which the front direction and the width direction are combined is the seat surface cover portion 5. Will act. However, according to the seat cover S according to the present invention, a reaction force against the external force in the composite direction in which the width direction of the vehicle and the front direction and the width direction are combined is also generated. It is also possible to prevent displacement of the seating surface cover portion 5 in the compound direction with the width direction.

  The seat cover is suitable as a seat cover that prevents the displacement of the seat with respect to the seating portion of the vehicle seat due to the movement of the occupant sitting on the vehicle, during the seating or when getting off the vehicle, and maintains the seating stability.
