[0003] [Patent Document 1] Patent Publication No. 2014-168233 Summary of the Invention [Problem to be solved by the invention]
[0004] In the rear seats of a vehicle, there is a problem that small objects that fall into the space fall downwards. When providing a member to prevent such small objects from falling, a configuration that can follow the individual dive-down of the left and right seats is required.
[0005] The present invention aims to provide a trim cover that can prevent small items that fall into the space formed between the rear portions of the left and right seat cushions of a vehicle rear seat in which the left and right seats can be dived down individually from falling to the lower side of the space, and a vehicle rear seat equipped with the trim cover. [Means for solving the problem]
[0006] The trim cover of the first aspect is a trim cover that forms the upholstery material of the left and right seat cushions of a vehicle rear seat in which the left and right seats can be dived down individually and a space that is open on both sides in the seat vertical direction is formed between the rear parts of the left and right seat cushions, and includes a left cover that covers the pad of the left seat cushion, a right cover that covers the pad of the right seat cushion, and a covering cloth that is placed in the space, and the covering cloth has a left cloth whose left edge is sewn to the left cover, a right cloth whose right edge is sewn to the right cover, a left central cloth whose upper edge is sewn to the right edge of the left cloth, a right central cloth whose upper edge is sewn to the left edge of the right cloth, and a connector that connects the lower edge of the left central cloth to the lower edge of the right central cloth.
[0007] In the trim cover of the first aspect, a left cover is placed over the pad of the left seat cushion of a vehicle rear seat in which the left and right seats can be independently dived down, and a right cover is placed over the pad of the right seat cushion. A space is formed between the rear portions of the left and right seat cushions, opening on both sides in the vertical direction of the seat. A concealing cloth provided by the trim cover is placed in this space. This concealing cloth includes a left cloth whose left edge is sewn to the left cover, a right cloth whose right edge is sewn to the right cover, a left center cloth whose upper edge is sewn to the right edge of the left cloth, and a right center cloth whose upper edge is sewn to the left edge of the right cloth. The lower edge of the left center cloth and the lower edge of the right center cloth are connected by a connector. As a result, if a small item falls into the space, it will be trapped between the left center cloth and the right center cloth. This prevents the small item from falling downward into the space.
[0008] In the trim cover of the second aspect, the left center cloth and the right center cloth of the first aspect are folded when the left and right seats are dived down, and the overlapping portions caused by the folding are sewn together.
[0009] In the trim cover of the second embodiment, the left and right center cloths are folded when the seat is dived down to the left or right. The left and right center cloths are sewn together at the overlapping portions caused by the above folding. This allows the left and right center cloths to be folded in a predetermined position.
[0010] The third aspect of the rear seat for a vehicle is a rear seat for a vehicle that has left and right seats that can be dived down individually, and has a space that is open on both sides in the vertical direction of the seat formed between the rear portions of the left and right seat cushions, and the upholstery material of the left and right seat cushions is made up of the trim cover described in claim 1 or claim 2.
[0011] In the vehicle rear seat of the third aspect, the left and right seats can be independently dived down, and a space that opens on both sides in the vertical direction of the seat is formed between the rear portions of the left and right seat cushions. The trim covers that form the upholstery materials of the left and right seat cushions are those of the first or second aspect, so the above-mentioned effects are obtained. [Effects of the Invention]
[0012] As described above, according to the present invention, small items that fall into the space formed between the rear portions of the left and right seat cushions of a rear seat for a vehicle in which the left and right seats can be dived down individually can be prevented from falling to the lower side of the space.

[0014] A vehicle rear seat 10 according to one embodiment of the present invention will be described below with reference to Figures 1 to 6. Note that in each figure, some reference numerals may be omitted to make the drawings easier to understand. Arrows FR, RH, and UP, which are appropriately depicted in each figure, respectively indicate the front, right, 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.
[0015] 1 to 3, a vehicle rear seat 10 according to this embodiment is, for example, a two-seater seat divided 5:5 in the left-right direction, and has two seats 10L, 10R aligned in the left-right direction. The left and right seats 10L, 10R can be dived down individually.
[0016] The left and right seats 10L, 10R each have seat cushions 12L, 12R that support the buttocks and thighs of the occupant, seat backs 14L, 14R that support the back of the occupant, and headrests 16L, 16R that support the head of the occupant. The left and right seats 10L, 10R are basically configured the same except that they are configured symmetrically.
[0017] The left and right seat cushions 12L, 12R each have a frame (not shown) which is a skeleton member, pads 18L, 18R which are cushioning materials attached to the frame, and covers 20L, 20R which are upholstery materials covering the pads 18L, 18R. Similarly, the left and right seat backs 14L, 14R each have a frame (not shown) which is a skeleton member, pads 22L, 22R which are cushioning materials attached to the frame, and covers 24L, 24R which are upholstery materials covering the pads.
[0018] The frames are made of, for example, press-formed metal plates or metal pipes. The pads 18L, 18R, 22L, and 22R are made of, for example, a foam such as urethane foam. The covers 20L, 20R, 24L, and 24R are formed into a bag shape by sewing together multiple skin pieces made of, for example, cloth, leather, synthetic leather, or the like.
[0019] The cover 20L of the left seat cushion 12L corresponds to the "left cover" in the present invention, and the cover 20R of the right seat cushion 12R corresponds to the "right cover" in the present invention. These covers 20L, 20R are components of the trim cover 20 according to this embodiment. Hereinafter, the cover 20L of the left seat cushion 12L will be referred to as the "left cover 20L," and the cover 20R of the right seat cushion 12R will be referred to as the "right cover 20R."
[0020] The front portions of the seat cushions 12L and 12R are connected to a floor F of the vehicle body via link members 26L and 26R, respectively. The upper ends of the link members 26L and 26R are connected to the frames of the seat cushions 12L and 12R so as to be rotatable about axes extending in the left-right direction, and the lower ends of the link members 26L and 26R are connected to the floor F of the vehicle body so as to be rotatable about axes extending in the left-right direction.
[0021] A pair of left and right cushion brackets 28 extending rearward and upward is provided at both left and right ends of the rear of the seat cushions 12L, 12R. Base ends (front ends) of the left and right cushion brackets 28 are fixed to the frames of the seat cushions 12L, 12R. Tip ends (rear ends) of the left and right cushion brackets 28 are connected to the left and right ends of the lower part of the seat backs 14L, 14R so as to be rotatable about an axis along the left-right direction.
[0022] The lower ends of the seat backs 14L, 14R are each provided with a leg 30 extending toward the floor F. The upper end of each leg 30 is fixed to the frame of the seat backs 14L, 14R. The lower end of each leg 30 is connected to the floor F of the vehicle body so as to be rotatable about an axis extending in the left-right direction.
[0023] In the left seat 10L, a four-joint link is formed by the seat cushion 12L, seat back 14L, link member 26L, and floor F. Similarly, in the right seat 10R, a four-joint link is formed by the seat cushion 12R, seat back 14R, link member 26R, and floor F. This allows the left and right seats 10L, 10R to be displaced relative to the floor F between a seatable position shown in FIGS. 1 and 2 and a dive-down position shown in FIG. 3.
[0024] 1 and 4, when the left and right seats 10L, 10R are in their seating positions, a space 32 that is open upward and downward is formed between the rear of the left seat cushion 12L and the rear of the right seat cushion 12R. A cushion bracket 28 extending from the right end of the left seat cushion 12L and a cushion bracket 28 extending from the left end of the right seat cushion 12R are disposed in this space 32. A resin cover 34 made of resin is disposed between these cushion brackets 28.
[0025] 4, a concealing cloth 36 is disposed in the space 32 in front of the resin cover 34. This concealing cloth 36, together with the left cover 20L and the right cover 20R, constitutes the trim cover 20 according to this embodiment. This concealing cloth 36 is a member that conceals the internal structures of the left and right seat cushions 12L, 12R to prevent the internal structures from being visible to occupants through the space 32.
[0026] 4 to 6, the covering cloth 36 is made up of a left cloth 38L, a right cloth 38R, a left central cloth 40L, a right central cloth 40R, and a J hook 42 and an arrow 44 that constitute the connector. The left cloth 38L, the right cloth 38R, the left central cloth 40L, and the right central cloth 40R are made up of a cloth material such as carpet. The J hook 42 and the arrow 44 are made up of resin, for example.
[0027] The left cloth 38L is disposed on the left side of the space 32, with the thickness direction being the up-down direction. The left edge of the left cloth 38L is sewn to the left cover 20L on the left side of the space 32, and the front edge is sewn to the left cover 20L on the front side of the space 32. The right cloth 38R is disposed on the right side of the space 32, with the thickness direction being the up-down direction. The right cloth 38R has the right edge sewn to the right cover 20R on the right side of the space 32, and the front edge is sewn to the right cover 20R on the front side of the space 32. As shown in FIG. 4 , a left extension 38R1 extending to the left is provided at the rear of the right cloth 38R. The left extension 38R1 is overlapped on the upper surface of the left cloth 38L.
[0028] 5 and 6, the right edge of the left cloth 38L is folded in half and sewn at a seam S1. The upper edge of the left central cloth 40L is sewn to this seam S1. Similarly, the left edge of the right cloth 38R is folded in half and sewn to a seam S2. The upper edge of the right central cloth 40R is sewn to this seam S2. A J hook 42 is attached to the lower edge of the left central cloth 40L, and an arrow 44 is attached to the lower edge of the right central cloth 40R.
[0029] J hook 42 is formed into an elongated shape by, for example, resin injection molding, and is arranged with its longitudinal direction in the front-to-rear direction. J hook 42 has a J-shaped cross section when viewed from the longitudinal direction, and is sewn to left central cloth 40L at sewn portion S3 provided on the lower edge of left central cloth 40L.
[0030] The arrow 44 is formed into an elongated shape by, for example, resin injection molding, and is arranged with its longitudinal direction extending in the front-to-rear direction. The cross section of the arrow 44 when viewed from the longitudinal direction is arrowhead-shaped, and the arrow 44 is sewn to the right central cloth piece 40R at a sewn section S4 provided on the lower edge of the right central cloth piece 40R. The arrow 44 fits into the J hook 42, thereby connecting the lower edge of the left central cloth piece 40L and the lower edge of the right central cloth piece 40R.
[0031] When the left and right seats 10L, 10R dive down individually, the left cloth 38L and the left central cloth 40L and the right cloth 38R and the right central cloth 40R move relatively in the front-to-rear direction (see arrow M in FIG. 4). This relative movement is absorbed by the flexibility of the left cloth 38L, the left central cloth 40L, the right cloth 38R, and the right central cloth 40R.
[0032] The left-side center cloth 40L and the right-side center cloth 40R are folded when the left and right seats 10L, 10R dive down, and the overlapping portions caused by the folding are sewn at seams S5, S6, S7, and S8. Note that Figure 6 shows the state in which only the left-side seat 10L has dived down.
[0033] Specifically, a substantially U-shaped folded portion that opens to the left in a front-to-back view is formed on the upper edge of the left central cloth 40L, and this folded portion is sewn at a sewn portion S5. Similarly, a substantially U-shaped folded portion that opens to the right in a front-to-back view is formed on the upper edge of the right central cloth 40R, and this folded portion is sewn at a sewn portion S6.
[0034] Furthermore, a substantially U-shaped folded portion that opens downward in a front-to-back view is formed on the lower edge of the left central cloth 40L, and this folded portion is sewn at a sewn portion S7. Similarly, a substantially U-shaped folded portion that opens downward in a front-to-back view is formed on the lower edge of the right central cloth 40R, and this folded portion is sewn at a sewn portion S8.
[0035] In the vehicle rear seat 10 configured as described above, the left and right seats 10L, 10R can be dived down individually. The pad 18L of the left seat cushion 12L is covered with a left cover 20L of a trim cover 20, and the pad 18R of the right seat cushion 12R is covered with a right cover 20R of the trim cover 20. A space 32 that is open on both vertical sides is formed between the rear portions of the left and right seat cushions 12L, 12R. A covering cloth 36 of the trim cover 20 is arranged in this space 32.
[0036] The covering cloth 36 includes a left cloth 38L having its left edge sewn to the left cover 20L, a right cloth 38R having its right edge sewn to the right cover 20R, a left center cloth 40L having its upper edge sewn to the right edge of the left cloth 38L, and a right center cloth 40R having its upper edge sewn to the left edge of the right cloth 38R. The lower edges of the left center cloth 40L and the right center cloth 40R are connected by a J hook 42 and an arrow 44. As a result, if a small object falls into the space 32 (see arrow D in FIG. 5), it will be trapped between the left center cloth 40L and the right center cloth 40R and will be held there. This prevents the small object from falling downward into the space 32. Furthermore, the left and right seats 10L, 10R are permitted to dive down by the bending of the left cloth 38L, left center cloth 40L, right cloth 38R, and right center cloth 40R.
[0037] The above effects will be further explained using a comparative example shown in Figures 7 and 8. In the covering cloth 100 according to this comparative example, the left cloth 102L and the right cloth 102R are overlapped in the vertical direction, so that the internal structures of the left and right seat cushions 12L, 12R can be covered and concealed. In addition, because the left cloth 102L and the right cloth 102R are not connected, dive-down of the left and right seats 10L, 10R can be tolerated.
[0038] However, because the left cloth 102L and the right cloth 102R are not restrained in the left-right direction, the shapes of the left cloth 102L and the right cloth 102R cannot be maintained (see arrow T in FIGS. 7 and 8). As a result, small items that fall into the space 32 will pass between the left cloth 102L and the right cloth 102R and fall to the lower side of the space 32 (see arrow D in FIG. 8). In this regard, in the present embodiment, small items that get caught between the left cloth 38L and the right cloth 38R will fall and be held between the left center cloth 40L and the right center cloth 40R. This makes it possible to effectively prevent small items from falling to the lower side of the space 32.
[0039] Furthermore, the left center cloth 40L and the right center cloth 40R are folded when the left and right seats 10L, 10R dive down, but the overlapping portions caused by the folding are sewn at stitching portions S5, S6, S7, and S8, which allows the left center cloth 40L and the right center cloth 40R to be folded as designed.
[0040] In the above embodiment, the connector is configured by the J hook 42 and the arrow 44, but the configuration of the connector is not limited to this and can be changed as appropriate.
[0041] In addition, in the above embodiment, the left side center cloth 40L and the right side center cloth 40R are configured such that the overlapping portions caused by the dive-down of the left and right seats 10L, 10R are sewn at the stitching portions S5, S6, S7, and S8, but this is not limited to this, and the stitching portions S5, S6, S7, and S8 may be omitted.
[0042] In addition, the present invention can be implemented with various modifications within the scope of the gist thereof. Furthermore, it goes without saying that the scope of the rights of the present invention is not limited to the above-described embodiment. [Explanation of symbols]
