Description

[Technical Field]

[0001] The present invention relates to a seat trim and a vehicle seat. [Background technology]

[0002] Patent Document 1 below discloses a headrest trim that forms part of a headrest. The headrest trim described in this document is formed in a bag shape with an opening at the bottom. The headrest trim is attached to the headrest pad by engaging a J-fastener with a member with an arrowhead cross section while covering the headrest pad. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-137368 Summary of the Invention [Problem to be solved by the invention]

[0004] However, if the longitudinal dimension of a J fastener increases, it is conceivable that the workability of the operation of fastening the J fastener to the member to which the J fastener is to be fastened will decrease.

[0005] In consideration of the above, the present invention aims to provide a seat trim and a vehicle seat that can prevent a decrease in the efficiency of the engagement work between a J fastener and a member to which the J fastener is engaged. [Means for solving the problem]

[0006] The seat trim of the first embodiment comprises a first upholstery and a second upholstery that form the surface of the occupant support portion that supports the body of a seated occupant; a J fastener that is formed in an elongated shape and is J-shaped when viewed longitudinally and is fixed to the end of the first upholstery; and a plurality of J fastener locking members that are formed in an elongated shape and shaped so that the J fastener can be locked when viewed longitudinally and are fixed to the end of the second upholstery while arranged side by side in the longitudinal direction, and the attached state is maintained by the J fastener being locked by the plurality of J fastener locking members.

[0007] The first and second upholstery layers constituting the seat trim of the first aspect form the surface of an occupant support portion that supports the body of a seated occupant. Here, a J fastener of the above configuration is fixed to an end of the first upholstery. Furthermore, multiple J fastener locking members of the above configuration are fixed to the second upholstery. With this configuration, a work procedure can be adopted in which a portion of the J fastener is locked to one J fastener locking member and another portion of the J fastener is locked to another J fastener locking member. This prevents the J fastener from disengaging from the J fastener locking member to which it is already locked when locking the J fastener to the multiple J fastener locking members. As a result, a decrease in the workability of the locking operation between the J fastener and the J fastener locking members can be prevented.

[0008] The seat trim of the second embodiment is the seat trim of the first embodiment, wherein the occupant support portion is a seat back that supports the back of a seated occupant from the rear side of the seat, the first upholstery forms the rear surface of the seat back, a portion of the second upholstery forms the front surface of the seat back, and another portion of the second upholstery wraps around from the lower side of the seat to the rear side of the seat back, the J fastener is fixed to the end of the first upholstery on the lower side of the seat, and a plurality of the J fastener engaging members are fixed to the end of the second upholstery on the rear side of the seat.

[0009] The first upholstery constituting the seat trim of the second embodiment constitutes the seat rear side surface of the seat back. A portion of the second upholstery constituting the seat trim of the second embodiment constitutes the seat front side surface of the seat back, and another portion of the second upholstery wraps around from the seat lower side to the rear side of the seat back. The J fastener of the above-described configuration is fixed to the end of the first upholstery on the seat lower side. The multiple J fastener locking members of the above-described configuration are fixed to the end of the rear side of the second upholstery. With this configuration, the J fastener and the multiple J fastener locking members can be locked together on the seat rear and seat lower sides of the seat back.

[0010] A vehicle seat of a third aspect comprises a seat cushion that supports the buttocks of a seated occupant from below the seat, a seat back that supports the back of the seated occupant from the rear side of the seat, a headrest that supports the head of the seated occupant from the rear side of the seat, a first upholstery and a second upholstery that form the surface of any of the seat cushion, the seat back, and the headrest, a J fastener that is formed in an elongated shape and is J-shaped when viewed longitudinally, and is fixed to an end of the first upholstery, and a plurality of J fastener locking members that are formed in an elongated shape and shaped so that the J fastener can be locked when viewed longitudinally, and are fixed to an end of the second upholstery while arranged side by side in the longitudinal direction, and the seat trim is maintained in an attached state by the J fastener being locked by the plurality of J fastener locking members.

[0011] A vehicle seat according to a third aspect includes a seat cushion, a seat back, and a headrest. The first and second upholstery layers constituting the seat trim of the vehicle seat of the third aspect form the surfaces of any of the seat cushion, the seat back, and the headrest. A J fastener having the above-described configuration is fixed to an end of the first upholstery. A plurality of J fastener locking members having the above-described configuration are fixed to the second upholstery. This configuration allows for a procedure in which a portion of the J fastener is locked to one J fastener locking member and another portion of the J fastener is locked to another J fastener locking member. This prevents the J fastener from disengaging from the J fastener locking member to which it is already locked when locking the J fastener to the plurality of J fastener locking members. As a result, the workability of locking the J fastener to the J fastener locking members is prevented from decreasing. [Effects of the Invention]

[0012] The seat trim and vehicle seat according to the present invention have the excellent effect of preventing a decrease in the efficiency of the locking operation between the J fastener and the member to which the J fastener is locked. [Brief explanation of the drawings]

[0014] 1 to 5, a vehicle seat 10 according to an embodiment of the present invention will be described. In the drawings, the arrow FR indicates the front side of the seat, the arrow UP indicates the upper side of the seat, the arrow RH indicates the right side in the seat width direction, and the arrow LH indicates the left side in the seat width direction. In the following description, unless otherwise specified, when referring to front-rear, up-down, and left-right directions, these refer to front-rear in the seat front-rear direction, up-down in the seat up-down direction, and left-right in the seat width direction.

[0015] 1, a vehicle seat 10 of this embodiment is a type of vehicle seat that can accommodate two or three occupants seated side by side in the left-right direction. The vehicle seat 10 includes a seat cushion 12 that supports the buttocks of the seated occupant from below, a seat back 14 that supports the back of the seated occupant from the rear side, and a headrest 16 that supports the head of the seated occupant from the rear side. The seat cushion 12, the seat back 14, and the headrest 16 are examples of an occupant support portion.

[0016] The seat cushion 12 includes a cushion frame (not shown) that forms the framework of the seat cushion 12, a cushion pad 18 attached to the cushion frame, and a cushion trim 20 that serves as seat trim that forms the surface of the seat cushion 12.

[0017] As shown in FIG. 2, the seatback 14 of this embodiment has a two-part structure divided laterally. The right-hand portion of the seatback 14 is referred to as the first seatback portion 14A, and the left-hand portion of the seatback 14 is referred to as the second seatback portion 14B. The upper portions of the first seatback portion 14A and the second seatback portion 14B can be locked to locking portions provided on the vehicle body. When the upper portions of the first seatback portion 14A and the second seatback portion 14B are locked to the locking portions provided on the vehicle body, the tilting of the first seatback portion 14A and the second seatback portion 14B relative to the seat cushion 12 is limited. Furthermore, by releasing the upper portions of the first seatback portion 14A and the second seatback portion 14B from the locking portions provided on the vehicle body, the first seatback portion 14A and the second seatback portion 14B can be tilted forward relative to the seat cushion 12.

[0018] The first seatback portion 14A is configured to include a back frame (not shown) that forms the framework of the first seatback portion 14A, a back pad 28 attached to the back frame, and a back trim 30 that serves as seat trim that forms the surface of the first seatback portion 14A. In addition, most of the back trim 30 of the first seatback portion 14A in this embodiment is configured by a first upholstery 32, a second upholstery 34, a third upholstery 36, a fourth upholstery 38, and a fifth upholstery 40.

[0019] The first skin 32 is formed in a sheet shape using polyvinyl chloride or the like. This first skin 32 constitutes most of the rear surface of the first seatback portion 14A. The first skin 32 is formed in a rectangular shape when viewed from the rear side.

[0020] The second upholstery 34 is made of cloth, synthetic leather, leather, or the like. The second upholstery 34 includes an upper covering portion 34A that covers the upper surface of the back pad 28, a front covering portion 34B that covers the front surface of the back pad 28, and a lower covering portion 34C that covers the lower surface of the back pad 28. The second upholstery 34 also includes a rear covering portion 34D that extends upward from the rear end of the lower covering portion 34C. The range of the second upholstery 34 from the lower covering portion 34C to the rear covering portion 34D wraps around from the lower side of the first seat back portion 14A to the rear side.

[0021] The third and fourth skins 36, 38 are made of cloth, synthetic leather, leather, etc., similar to the second skin 34. The third and fourth skins 36, 38 cover the right and left sides of the back pad 28, respectively.

[0022] The fifth skin 40 is formed in a sheet shape using polyvinyl chloride or the like, similar to the first skin 32. The fifth skin 40 forms the right end portion of the rear surface of the first seatback portion 14A.

[0023] The upper end of the first skin 32 described above is joined by sewing or the like to the rear end of the upper covering portion 34A of the second skin 34. The upper, front, and rear ends of the third skin 36 are joined by sewing or the like to the upper covering portion 34A, front covering portion 34B of the second skin 34, and the right end of the fifth skin 40. The upper and front ends of the fourth skin 38 are joined by sewing or the like to the upper covering portion 34A and front covering portion 34B of the second skin 34. The right end of the first skin 32 and the left end of the fifth skin 40 are connected via a fastener. The left end of the first skin 32 and the rear end of the fourth skin 38 are connected via a fastener. The lower end of the first skin 32 and the rear end of the rear covering portion 34D of the second skin 34 are connected via a J fastener 42 and two J fastener locking members 44, which will be described later.

[0024] 2 and 3, a J fastener 42 is fixed to the lower end 32A of the first upholstery 32. In other words, when the lower end 32A of the first upholstery 32 is turned up as shown in FIGS. 2 and 3, the J fastener 42 is fixed to the lower end 32A of the first upholstery 32. The J fastener 42 is formed in an elongated shape with its longitudinal direction extending in the left-right direction and is formed in a substantially J-shape when viewed in the longitudinal direction. More specifically, the J fastener 42 includes a first extending portion 42A that extends in the left-right direction and is fixed to the lower end 32A of the first upholstery 32 by sewing or the like, and a second extending portion 42C that extends from one end of the first extending portion 42A via a bent portion 42B to the opposite side of the first extending portion 42A. J fastener 42 also includes a U-shaped portion 42D folded back into a U shape from the end of second extending portion 42C opposite bent portion 42B, and a third extending portion 42E extending from the end of U-shaped portion 42D opposite second extending portion 42C toward first extending portion 42A. J fastener 42 also includes a locking projection 42F projecting from second extending portion 42C toward third extending portion 42E.

[0025] As shown in Figures 2 and 4, two J fastener locking members 44 are fixed to the rear end 34E of the rear covering portion 34D of the second upholstery 34 in a state of being arranged side by side in the left-right direction. These J fastener locking members 44 are formed in an elongated shape with the left-right direction as the longitudinal direction and are formed in an arrowhead shape with one end pointed when viewed in the longitudinal direction. More specifically, the J fastener locking member 44 includes a base plate portion 44A that extends in the left-right direction and is fixed to the rear end 34E of the rear covering portion 34D of the second upholstery 34 by sewing or the like. The J fastener locking member 44 also includes a locking projection 44B that projects rearward from the upper end of the base plate portion 44A (the upper end when the J fastener locking member 44 is fixed to the rear end 34E of the rear covering portion 34D of the second upholstery 34).

[0026] The second seatback portion 14B is configured similarly to the first seatback portion 14A, except that the second seatback portion 14B is smaller in size in the seat width direction than the first seatback portion 14A and is equipped with a single J-fastener locking member 44. Therefore, the members and parts of the second seatback portion 14B that correspond to those of the first seatback portion 14A will be assigned the same reference numerals as those of the first seatback portion 14A, and their explanation will be omitted.

[0027] (Actions and Effects of This Embodiment) Next, the operation and effects of this embodiment will be described.

[0028] As shown in FIG. 2, in the vehicle seat 10 of the present embodiment described above, the following assembly procedure can be adopted when assembling the first seatback portion 14A.

[0029] 2, first, the back pad 28 is attached to the back frame, and then the back trim 30 is placed from above over the back pad 28 and the back frame with the fasteners open. Next, one fastener is closed to connect the right end of the first skin 32 to the left end of the fifth skin 40. Furthermore, the other fastener is closed to connect the left end of the first skin 32 to the rear end of the fourth skin 38.

[0030] 2 and 5, second extension portion 42C, U-shaped portion 42D, and third extension portion 42E of J fastener 42 are hooked onto the lower end portion of one of the J fastener locking members 44, thereby locking a portion of J fastener 42 to one of the J fastener locking members 44. Note that when the locking of a portion of J fastener 42 to one of the J fastener locking members 44 is complete, the lower end portion of one of the J fastener locking members 44 is fitted between second extension portion 42C, U-shaped portion 42D, and third extension portion 42E of the portion of J fastener 42, and locking projection 44B of one of the J fastener locking members 44 and locking projection 42F of J fastener 42 are locked. This prevents the portion of J fastener 42 from coming off one of the J fastener locking members 44.

[0031] Next, the second extension portion 42C, U-shaped portion 42D, and third extension portion 42E of the J fastener 42 are hooked onto the lower end portion of the other J fastener locking member 44, thereby locking another portion of the J fastener 42 to the other J fastener locking member 44. Note that, when the locking of the other portion of the J fastener 42 to the other J fastener locking member 44 is complete, the lower end portion of the other J fastener locking member 44 is fitted between the second extension portion 42C, U-shaped portion 42D, and third extension portion 42E of the other portion of the J fastener 42, and the locking projection 44B of the other J fastener locking member 44 and the locking projection 42F of the J fastener 42 are locked together. This prevents the other portion of the J fastener 42 from coming off the other J fastener locking member 44. As a result, the back trim 30 is maintained in an attached state.

[0032] As described above, in this embodiment, the above assembly procedure can be adopted by configuring multiple J fastener locking members 44 to be aligned in the longitudinal direction of the J fastener locking member 44 (in other words, by configuring the J fastener locking member 44 to be divided in the longitudinal direction of the J fastener locking member 44). This makes it possible to prevent a J fastener 42 from disengaging from a J fastener locking member 44 to which the J fastener 42 is already locked when locking the J fastener 42 with the multiple J fastener locking members 44. That is, in the above example, when locking another portion of the J fastener 42 with the other J fastener locking member 44, it is possible to prevent a portion of the J fastener 42 from disengaging from one of the J fastener locking members 44. As a result, it is possible to prevent a decrease in the efficiency of the locking operation between the J fastener 42 and the J fastener locking members 44. In addition to the J fastener 42 becoming longer, in a configuration in which the J fastener locking member 44 is not divided longitudinally, if a poor locking relationship occurs between a part of the J fastener 42 and a part of the J fastener locking member 44 due to warping of the two or the like, the J fastener 42 and the J fastener locking member 44 are likely to come loose along their entire longitudinal length.

[0033] In this embodiment, the configuration of the present invention is applied to the first seat back portion 14A, but the present invention is not limited to this. For example, the configuration of the present invention can be applied to the second seat back portion 14B, or can be applied to the seat cushion 12 or the headrest 16.

[0034] Furthermore, in this embodiment, an example has been described in which the J fastener 42 and J fastener locking member 44 configured as described above are used, but the present invention is not limited to this. The configuration of the J fastener 42 and J fastener locking member 44 may be set appropriately taking into consideration requirements such as the difficulty of disengagement between the J fastener 42 and the J fastener locking member 44. Also, a configuration in which one J fastener 42 is locked to three or more J fastener locking members 44 may be employed.

[0035] The above describes one embodiment of the present invention, but the present invention is not limited to the above, and it goes without saying that it can be implemented in various other modified forms within the scope of the gist of the present invention. [Explanation of symbols]
