Description

[Technical Field]

[0001] The present invention relates to a rear seat for a vehicle, and more particularly to a trim cover. [Background technology]

[0002] Patent Document 1 below discloses a rear seat for a vehicle. This rear seat is equipped with a seat back that can be folded forward. The seat back's covering material has slits formed at both left and right ends of the seat. Strikers provided on the sides of the vehicle body are inserted into these slits, and the strikers engage with locking devices provided within the seat back. This restrains the seat back in an upright position. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-121549 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-described rear seat for a vehicle, the internal components of the seat back may be visible through a slit formed in the seat back cover material. Furthermore, the position of the slit relative to the pad may become misaligned due to variations in assembly or loads during use. Therefore, there is room for improvement in terms of improving the appearance quality of the seat back.

[0005] An object of the present invention is to provide a trim cover that can improve the appearance quality of a seat back in a configuration in which a slit into which a striker is inserted is formed, and a rear seat for a vehicle that is equipped with the trim cover. [Means for solving the problem]

[0006] The trim cover of the first aspect comprises a cover body that is placed over the pad of the seat back of a vehicle rear seat; a slit formed in the cover body into which a striker fixed to the side of the vehicle body is inserted; a covering cloth that is sewn to the edge of the slit in the cover body and covers a striker insertion groove formed in the pad opposite the slit; and a plate-shaped member that is attached to an end portion of the covering cloth and is sandwiched between the frame of the seat back and the pad.

[0007] In the trim cover of the first aspect, a cover body is placed over the pad of a seat back of a vehicle rear seat. A slit is formed in the cover body, into which a striker fixed to the side of the vehicle body is inserted. A covering cloth is sewn to the edge of the slit in the cover body, and a striker insertion groove formed in the pad opposite the slit is covered by the covering cloth. This makes it possible to prevent the internal components of the seat back from being seen through the slit. In addition, a plate-shaped member is attached to an end portion of the covering cloth. This plate member is sandwiched between the frame of the seat back and the pad. This makes it possible to prevent the covering cloth and the slit (i.e., the cover body) from being misaligned with respect to the pad. As a result, the appearance quality of the seat back can be improved.

[0008] In the trim cover of the second aspect, in the first aspect, the slit and the striker insertion groove open to the rear side of the seat when viewed in the left-right direction of the seat, and the plate member is approximately U-shaped and opens to the rear side of the seat when viewed in the left-right direction of the seat.

[0009] In the trim cover of the second aspect, the plate member has a generally U-shape that opens toward the rear of the seat when viewed from the left and right, similar to the slit and the striker insertion groove. This plate member is sewn to an end portion of the covering cloth and is sandwiched between the frame of the seatback and the pad, thereby effectively suppressing misalignment of the covering cloth and the slit relative to the pad.

[0010] The trim cover of the third aspect is the first or second aspect, in which at least a portion of one of the terminal portion of the coated cloth and the plate member is in surface contact with one of the frame and the pad, and at least a portion of the other of the terminal portion of the coated cloth and the plate member is in surface contact with the other of the frame and the pad.

[0011] In the trim cover of the third aspect, the end portion of the covering cloth and at least a part of the plate member are in surface contact with the frame and pad of the seat back as described above, which increases the pressure-receiving area compared to point contact, making it difficult for the end portion of the covering cloth and the plate member to accidentally slip out from between the frame and pad.

[0012] A trim cover of a fourth aspect is any one of the first to third aspects, wherein the plate member contacts the pad.

[0013] In the trim cover of the fourth aspect, the plate member comes into contact with the pad of the seat back, and the end of the plate member bites into the pad, making it difficult for the plate member to shift position relative to the pad.

[0014] The trim cover of the fifth aspect is any one of the first to fourth aspects, wherein the covering cloth has a bent portion that is bent in a cross-sectional arc shape along the edge of the striker insertion groove in the pad, and the plate member is positioned so as not to be interposed between the bent portion and the pad.

[0015] In the trim cover of the fifth aspect, since no plate member is interposed between the bent portion of the covering fabric and the pad as described above, the shape of the bent portion of the covering fabric can be prevented from being distorted.

[0016] A sixth aspect of the rear seat for a vehicle includes a seat cushion on which an occupant sits, and a seat back in which the cover body of the trim cover of any one of the first to fifth aspects is placed over a pad, supporting the back of the occupant.

[0017] In the vehicle rear seat of the sixth aspect, the back of an occupant seated on a seat cushion is supported by the seat back. The trim cover in which the cover body is placed on the pad of this seat back is any one of the first to fifth aspects, and therefore the above-mentioned effects can be obtained. [Effects of the Invention]

[0018] As described above, in the trim cover and the vehicle rear seat according to the present invention, the appearance quality of the seat back can be improved when the trim cover and the vehicle rear seat have a configuration in which a slit into which a striker is inserted is formed.

DETAILED DESCRIPTION OF THE INVENTION

[0020] Hereinafter, a vehicle rear seat 10 according to one embodiment of the present invention will be described with reference to Figures 1 to 9. Note that in each figure, some reference numerals may be omitted to make the drawings easier to understand. Arrows FR, LH, and UP, which are appropriately depicted in each figure, respectively indicate the front, left, and top of the vehicle rear seat 10. Hereinafter, when the front-rear, left-right, top-bottom directions are used in the description, they will indicate directions relative to the vehicle rear seat 10.

[0021] As shown in Fig. 1, a vehicle rear seat 10 according to this embodiment is a three-seater rear seat and includes a seat cushion 12 on which occupants sit, a seatback 14 that supports the backs of the occupants, and three headrests 16 that support the heads of the occupants. The seatback 14 is divided into a right seatback 14R for two-seater use and a left seatback 14L for one-seater use. The right seatback 14R and the left seatback 14L are each connected to the floor of the vehicle body via hinge brackets (not shown) and can be folded forward onto the seat cushion 12.

[0022] The left and right seat backs 14L, 14R each include a frame 18 (see FIGS. 4 and 5) which is a framework member, a pad 20 which is a cushioning material attached to the frame 18, and a trim cover 30 which is a skin covering the pad 20. The frame 18 is formed by joining together, for example, press-formed metal plates or metal pipes. The pad 20 is formed, for example, from a foam such as urethane foam.

[0023] The trim cover 30 has a cover body 32 that covers the pad 20, a covering cloth 36 sewn to the cover body 32, and a plate member 38 attached to the covering cloth 36. The cover body 32 is formed into a bag shape by sewing together a plurality of skin pieces made of, for example, cloth, leather, synthetic leather, or the like, and is placed over the pad 20 from above. The cover body 32 is formed with a slit 34 (see FIGS. 1 to 5) into which a striker 24 (see FIG. 4) fixed to the side of the vehicle body is inserted.

[0024] The striker 24 is formed, for example, from a metal wire and is generally U-shaped when viewed from the top and bottom of the vehicle. The striker 24 is fixed to the side of the vehicle body via a bracket (not shown) made, for example, of a press-formed metal plate. The striker 24 is provided on both the left and right sides of the vehicle body.

[0025] Locking devices 26 (see FIGS. 4 and 5) are provided inside the left and right seat backs 14L, 14R corresponding to the left and right strikers 24. Each locking device 26 is fixed to the frame 18 of each seat back 14L, 14R. When each seat back 14L, 14R is in an upright position (the position shown in FIG. 1), a latch (not shown) provided on each locking device 26 engages with the corresponding striker 24, restraining each seat back 14L, 14R in the upright position. This restraint is configured to be released by operating a lock release lever (not shown) provided on each seat back 14L, 14R.

[0026] The areas around the locking device 26 in the left and right seat backs 14L, 14R are basically configured in the same way except that they are symmetrical, so the following will describe the area around the locking device 26 in the left seat back 14L. The directions of front, back, left, right, up and down used in the following description refer to the directions when the seat back 14L is in the upright position.

[0027] 2 to 5, the slit 34 formed in the cover main body 32 opens rearward in a left-right view and also opens to the left (outside in the vehicle width direction) in a front-to-rear view. Corresponding to this slit 34, the pad 20 is formed with a striker insertion groove 22 into which the striker 24 is inserted. This striker insertion groove 22 is disposed opposite the slit 34 and opens rearward in a left-right view and also opens to the left (outside in the vehicle width direction) in a front-to-rear view. The vertical width dimension of the striker insertion groove 22 and the vertical width dimension of the slit 34 are set to be equal, and the striker insertion groove 22 and the slit 34 are disposed so as to be aligned in the vertical direction.

[0028] 4 and 5, a covering cloth 36 is sewn to the edge of the slit 34 in the cover main body 32. The covering cloth 36 is made of, for example, a cloth material, and covers the striker insertion groove 22. The covering cloth 36 has a shape that matches the periphery of the striker insertion groove 22 in the pad 20, and is configured so that the pad 20 cannot be seen through the slit 34 from outside the seat back 14L.

[0029] The covering cloth 36 has an upper surface covering portion 36A that covers the upper surface of the striker insertion groove 22, a lower surface covering portion 36B that covers the lower surface of the striker insertion groove 22, and a front surface covering portion 36C that covers the front surface of the striker insertion groove 22. Furthermore, the covering cloth 36 has an upper terminal portion 36D that extends upward from the right end of the upper surface covering portion 36A, a lower terminal portion 36E that extends downward from the right end of the lower surface covering portion 36B, a front terminal portion 36F that extends forward from the right end of the front surface covering portion 36C, an upper extension portion 36G that extends upward from the rear end of the upper surface covering portion 36A, and a lower extension portion 36H that extends downward from the rear end of the lower surface covering portion 36B.

[0030] As shown in Fig. 6, the upper terminal portion 36D and the lower terminal portion 36E are connected via the front terminal portion 36F. The upper terminal portion 36D, the lower terminal portion 36E, and the front terminal portion 36F are sandwiched between the frame 18 and the pad 20. The upper terminal portion 36D, the lower terminal portion 36E, and the front terminal portion 36F constitute the "terminal portion" in the present invention. Hereinafter, the upper terminal portion 36D, the lower terminal portion 36E, and the front terminal portion 36F will be referred to as the "terminal portion 37."

[0031] The terminal portion 37 has a generally U-shape (approximately C-shape) that opens rearward when viewed from the left and right. A plate member 38 is attached to the terminal portion 37. The plate member 38 is made of, for example, a resin plate material, and is disposed (sandwiched) between the terminal portion 37 and the pad 20 with the left and right direction being the plate thickness direction.

[0032] This plate member 38 integrally includes an upper plate portion 38A arranged between upper terminal portion 36D and pad 20, a lower plate portion 38B arranged between lower terminal portion 36E and pad 20, and a front plate portion 38C arranged between front terminal portion 36F and pad 20, and is generally U-shaped (or generally C-shaped) that is open to the rear when viewed from the left and right. This plate member 38 has cutouts 40 formed at the front and upper end, rear and upper end, front and lower end, and rear and lower end, respectively, and the plate member 38 is cut diagonally at each of the cutouts 40.

[0033] 6, the plate member 38 is sewn to the terminal portion 37, and is sandwiched together with the terminal portion 37 between the frame 18 and the pad 20. The plate member 38 is in surface contact with the pad 20, and a portion of the terminal portion 37 is in surface contact with the frame 18.

[0034] 4 and 5, the covering cloth 36 has bent portions R1, R2, and R3 between the upper surface covering portion 36A and the upper terminal portion 36D, between the lower surface covering portion 36B and the lower terminal portion 36E, and between the front surface covering portion 36C and the front terminal portion 36F, respectively. The bent portions R1, R2, and R3 are bent in an arc-shaped cross section along the edge of the striker insertion groove 22 in the pad 20. The plate member 38 is positioned so as not to be interposed between the bent portions R1, R2, and R3 and the pad 20. The edge of the plate member 38 on the striker insertion groove 22 side is positioned where the R of the bent portions R1, R2, and R3 ends.

[0035] As shown in Fig. 7, the upper extension 36G and the lower extension 36H of the covering cloth 36 are disposed between the cover main body 32 and the pad 20 on the rear side of the seat back 14L. These upper extension 36G and lower extension 36H are sewn to the cover main body 32 at stitching portions S3 and S4 located at the left end of the rear side of the seat back 14L. This prevents the covering cloth 36 from being turned up inward into the striker insertion groove 22 (see arrow T in Fig. 7). The stitching portions S3 and S4 are configured so as not to be visible from the rear side of the seat back 14L.

[0036] When manufacturing the seat back 14L configured as described above, for example, as shown in Fig. 8, the trim cover 30 is placed on the pad 20, and then as shown in Fig. 9, the plate member 38 and the covering cloth 36 are inserted into the striker insertion groove 22, and the plate member 38 and the terminal portion 37 are sandwiched between the frame 18 and the pad 20. At this time, the aforementioned cutout portion 40 is formed in the plate member 38, thereby improving the workability of the assembly work.

[0037] In the vehicle rear seat 10 configured as described above, the back of an occupant seated on the seat cushion 12 is supported by the seat back 14L. A cover body 32 of a trim cover 30 is placed over the pad 20 of the seat back 14L. A slit 34 is formed in the cover body 32, into which a striker 24 fixed to the side of the vehicle body is inserted. A covering cloth 36 is sewn to the edge of the slit 34 in the cover body 32, and the striker insertion groove 22 formed in the pad 20 opposite the slit 34 is covered by the covering cloth 36. This makes it possible to prevent the internal components of the seat back 14L from being seen through the slit 34.

[0038] Furthermore, a plate-shaped plate member 38 is attached to an end portion 37 of the covering cloth 36. This plate member 38 is sandwiched between the frame 18 of the seat back 14L and the pad 20. This applies tension to the covering cloth 36 and the cover main body 32, which prevents the covering cloth 36 and the slits 34 (i.e., the cover main body 32) from shifting position relative to the pad 20 and prevents wrinkles from occurring in the covering cloth 36 and the cover main body 32. As a result, the appearance quality of the seat back 14L can be improved.

[0039] The above-described effects will be further explained using a comparative example shown in Figures 10 to 13. In Figures 10 to 13, the same reference numerals are used to designate components that are essentially the same as those in this embodiment. In this comparative example, the plate member 38 is not attached to the end portion 37 of the covering cloth 36. Therefore, for example, an external force from an occupant may cause the covering cloth 36 or the slit 34 to become misaligned with respect to the pad 20, or the covering cloth 36 may be pulled out of the slit 34. This may result in a deterioration in the appearance quality of the seat back 14L, but this can be avoided in this embodiment.

[0040] Furthermore, in this comparative example, the periphery of the striker insertion groove 22 in the pad 20 is not entirely covered by the covering cloth 36, and therefore the pad 20 may be visible to the occupant depending on, for example, the seat arrangement or the occupant's eye point depending on the vehicle state. In this regard, in the present embodiment, the periphery of the striker insertion groove 22 in the pad 20 is entirely covered by the covering cloth 36, and therefore the pad 20 can be prevented from being visible to the occupant.

[0041] Furthermore, in this comparative example, the vertical width of the striker insertion groove 22 is set larger than the vertical width of the slit 34, and the portion of the trim cover 30 surrounding the slit 34 is not supported by the pad 20. This tends to cause variations in the assembly position of the slit 34 relative to the pad 20, and in practical use, the portion of the trim cover 30 surrounding the slit 34 is likely to be crushed. As a result, the appearance quality of the seat back 14L becomes unstable.

[0042] In contrast, in this embodiment, the vertical width dimension of the striker insertion groove 22 and the vertical width dimension of the slit 34 are set to be equal, and the peripheral portion of the slit 34 in the trim cover 30 is supported by the pad 20, which makes it less likely that variations will occur in the assembly position of the slit 34 relative to the pad 20 and prevents crushing of the peripheral portion of the slit 34 in the trim cover 30. This also makes it possible to improve the appearance quality of the seat back 14L.

[0043] Furthermore, in this embodiment, the plate member 38 has a generally U-shape that opens rearward when viewed in the left-right direction, similar to the slit 34 and the striker insertion groove 22. This plate member 38 is sewn to the end portion 37 of the covering cloth 36 and is sandwiched between the frame 18 and the pad 20, thereby effectively preventing the covering cloth 36 and the slit 34 from shifting in position relative to the pad 20.

[0044] In addition, in this embodiment, the plate member 38 is in surface contact with the pad 20, and a portion of the terminal portion 37 of the covering cloth 36 is in surface contact with the frame 18, so the pressure-receiving area can be increased compared to point contact. As a result, the plate member 38 and the terminal portion 37 are less likely to accidentally come out from between the frame 18 and the pad 20.

[0045] Furthermore, in this embodiment, the plate member 38 is in contact with the pad 20 , and the end of the plate member 38 bites into the pad 20 , making it difficult for the plate member 38 to become misaligned with respect to the pad 20 .

[0046] Furthermore, in this embodiment, the covering cloth 36 has bent portions R1, R2, R3 that are bent in an arc-shaped cross section along the edge of the striker insertion groove 22 in the pad 20, and the plate member 38 is arranged so as not to be interposed between the bent portions R1, R2, R3 and the pad 20. This prevents the plate member 38 from destroying the shape of the bent portions R1, R2, R3.

[0047] Although the present invention has been described above by showing the embodiments, the present invention can be practiced with various modifications within the scope of the gist thereof. Furthermore, it goes without saying that the scope of the present invention is not limited to the above-described embodiments. [Explanation of symbols]
