Description

[Technical Field]

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

[0002] The mounting structure for the covering material disclosed in Patent Document 1 below includes a pad with an opening and a slit formed therein, a trim cover that covers the surface of the pad and has a flap that is housed in the slit, and an operating lever member that is inserted into the opening with the flap housed in the slit, is fixed to the frame, and presses the pad. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-128246 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above prior art, when the trim cover is pulled by an occupant, the flap may slip out of the slit, and the pad or frame may become visible between the flap (i.e., the end portion of the trim cover) and the operating lever member.

[0005] To provide a trim cover and a vehicle seat equipped with the trim cover, which can prevent a pad or a frame from being seen between the terminal part of the cover body and an operating lever member even when the cover body is pulled by an occupant. [Means for solving the problem]

[0006] The trim cover of the first embodiment is placed over the pad of the seat back of a vehicle seat and comprises a cover body having a locking portion at its terminal end that is positioned in the gap between the pad and an escutcheon of an operating lever member that is provided at the shoulder of the seat back and fixed to the frame of the seat back, and a stopper member that is attached to the locking portion and engages with the escutcheon to prevent the locking portion from slipping out of the gap.

[0007] In the trim cover of the first aspect, the cover body is placed over the pad of the seat back of a vehicle seat. A locking portion provided at the end of the cover body is positioned in the gap between the pad and an escutcheon of an operating lever member provided at the shoulder of the seat back and fixed to the frame of the seat back. A retaining member attached to the locking portion engages with the escutcheon to prevent the locking portion from coming out of the gap. This prevents the pad or frame from being seen between the end of the cover body and the operating lever member, even if the cover body is pulled by an occupant.

[0008] In the trim cover of the second aspect, in the first aspect, the retaining member is a plate-like member formed in a plate shape.

[0009] In the trim cover of the second aspect, a plate-like member attached to the locking portion of the cover body engages with the escutcheon, preventing the locking portion from slipping out from the gap between the escutcheon and the pad. Because this plate-like member is formed in a plate shape and is placed between the escutcheon and the pad, the locking operation is easier than, for example, a configuration in which a locking member is inserted into a hole formed in the frame of the seat back and locked.

[0010] The trim cover of a third aspect is the trim cover of the second aspect, wherein the plate-like member is sewn to the engaging portion.

[0011] In the trim cover of the third aspect, the plate-like member is sewn to the engaging portion of the cover body, so that the plate-like member is easier to attach than, for example, a configuration in which the plate-like member is glued to the engaging portion.

[0012] The trim cover of the fourth aspect is the second or third aspect, in which the plate-shaped member is sandwiched together with the engaging portion between the vertical wall portion of the case of the operating lever member and the hanging wall portion of the escutcheon.

[0013] In the trim cover of the fourth aspect, the plate-like member attached to the locking portion of the cover body is sandwiched together with the locking portion between the vertical wall portion of the case of the operating lever member and the hanging wall portion of the escutcheon of the operating lever member, thereby enabling the locking portion to be securely locked between the vertical wall portion and the hanging wall portion.

[0014] A vehicle seat of the fifth aspect 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 fourth aspects is placed over a pad, supporting the back of the occupant.

[0015] In the vehicle seat of the fifth 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 third aspects, and therefore the above-mentioned effects can be obtained. [Effects of the Invention]

[0016] As described above, the trim cover and vehicle seat of the present invention can prevent the pad or frame from being visible between the terminal portion of the cover body and the operating lever member, even if the cover body is pulled by the occupant. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0018] A vehicle seat 10 according to one embodiment of the present invention will be described below with reference to Figures 1 to 7. 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 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 seat 10.

[0019] As shown in Figure 1, the vehicle seat 10 is a split-folding rear seat for three passengers, and includes a seat cushion 12 on which passengers sit, a seatback 14 that supports the passengers' backs, and three headrests 16 that support the passengers' heads. The seatback 14 is divided into a right seatback 14R for two passengers and a left seatback 14L for one passenger. The right seatback 14R and the left seatback 14L are each connected to the floor of the vehicle body via hinge brackets 18 and can be folded forward onto the seat cushion 12.

[0020] 1 to 6, the left and right seat backs 14 include a back frame 20 (see FIGS. 3 to 6) which is a frame, a back pad 24 which is a cushioning material, and a trim cover 28 which is a cover. The back frame 20 is made of, for example, a press-formed metal plate material or a metal pipe material, and is connected to the floor of the vehicle body via the hinge bracket 18.

[0021] The back pad 24 is made of a foam such as urethane foam, and is attached to the back frame 20. The back pad 24 has a rectangular shape when viewed from the front-to-rear direction of the seat back 14, and is a generally rectangular plate with its thickness direction aligned with the front-to-rear direction of the seat back 14. The trim cover 28 has a cover body 30 formed into a bag shape by sewing together multiple skin pieces made of, for example, cloth, leather, synthetic leather, etc. The cover body 30 is placed over the back pad 24 from above.

[0022] The left and right seatbacks 14R, 14L are each provided with a locking device 42 for restraining the left and right seatbacks 14R, 14L against the side of the vehicle body (not shown) in an upright position (the position shown in FIG. 1; hereinafter referred to as the "upright position"). The locking device 42 has a locking body 44 provided on the outer side of the left and right seatbacks 14R, 14L in the lateral direction, and an operating lever member 46 provided on the outer shoulder of the left and right seatbacks 14R, 14L in the lateral direction. The locking body 44 has a latch (not shown) that engages with a striker (not shown) provided on the side of the vehicle body. This engagement restrains the left and right seatbacks 14R, 14L in the upright position.

[0023] The configurations of the left and right seat backs 14R, 14L around the locking device 42 are basically the same except that they are configured symmetrically, so the following will describe the configuration of the right seat back 14R shown in Figures 2 to 4, and will omit a description of the configuration of the left seat back 14L. Furthermore, when the following description uses the front-rear, left-right, up-down directions, these directions refer to the state when the seat back 14R is in the upright position.

[0024] The operating lever member 46 has a case 48 fixed to the back frame 20 of the seat back 14R, an escutcheon 50 attached to the upper end of the case 48, and a lever 52 attached rotatably to the case 48. The case 48, escutcheon 50, and lever 52 are manufactured by, for example, injection molding of resin.

[0025] 3 to 6, the back frame 20 of the seat back 14R has a bracket 22 for fixing the case 48. The bracket 22 is made of, for example, a press-formed metal plate. A hole 23 into which the case 48 is inserted is formed in the bracket 22, and the case 48 is fixed to the bracket 22 by means of a claw engagement or the like.

[0026] The escutcheon 50 is disposed exposed on the upper surface of the seat back 14R and is fixed to the upper end of the case 48 by means of a claw engagement or other means. The lever 52 is attached to the case 48 so as to be rotatable about an axis along the left-right direction and is connected to the lock body 44 via a cable, link, or the like (not shown). The lever 52 has an operating portion 52A disposed exposed on the upper surface of the seat back 14R. When the occupant operates the operating portion 52A to rotate the lever 52, the latch of the lock body 44 rotates and disengages from the striker on the side of the vehicle body. This allows the seat back 14R to be tilted forward.

[0027] As shown in Figure 7, an upper wall portion 24A extending rearward is provided at the upper end of the back pad 24, and a case 48 of the operating lever member 46 is inserted into an opening 26 formed in the upper wall portion 24A. This opening 26 passes through the upper wall portion 24A in the vertical direction and is open on the rear side. An escutcheon 50 of the operating lever member 46 covers the edge of the opening 26 of the back pad 24 from above.

[0028] An end portion 30A of the cover body 30 of the trim cover 28 is wrapped around the edge of the opening 26 of the back pad 24. This end portion 30A has a right wrapping portion 30AR (see FIGS. 5 and 6) wrapped around the right edge of the opening 26, a left wrapping portion (not shown) wrapped around the left edge of the opening 26, and a front wrapping portion (not shown) wrapped around the front edge of the opening 26.

[0029] The right hanging portion 30AR is provided with a tongue-shaped locking portion 32 that is locked to the operating lever member 46. This locking portion 32 has a horizontal portion 32A that extends leftward from the main body of the right hanging portion 30AR, and a downward extending portion 32B that extends downward from the left end of the horizontal portion 32A. This locking portion 32 is disposed between the escutcheon 50 and the back pad 24. In addition to the locking portion 32, a vertical wall portion 48A provided on the case 48 of the operating lever member 46 and an I-hook 34, which is a plate-shaped member, are disposed between the escutcheon 50 and the back pad 24. This will be explained in detail below.

[0030] As shown in Figures 2 and 6, the escutcheon 50 integrally comprises a top wall portion 50A exposed on the upper surface of the seat back 14R, a rear wall portion 50B disposed on the rear surface of the seat back 14R, and a hanging wall portion 50C extending downward from the underside of the top wall portion 50A. As shown in Figures 3 to 6, a vertical wall portion 48A is provided at the right end of the case 48, facing the hanging wall portion 50C from the right side with a gap therebetween. This vertical wall portion 48A is integrally connected to a bottom wall portion 48B of the case 48. An opening 49 (see Figure 4) is formed at the end of the bottom wall portion 48B on the side of the vertical wall portion 48A.

[0031] The locking portion 32 provided on the right winding portion 30AR of the cover body 30 has a horizontal portion 32A sandwiched between the top wall portion 50A of the escutcheon 50 and the vertical wall portion 48A of the case 48, and a downward extending portion 32B disposed between the hanging wall portion 50C of the escutcheon 50 and the vertical wall portion 48A of the case 48. An I-hook 34 is disposed between the downward extending portion 32B and the vertical wall portion 48A.

[0032] The I-hook 34 corresponds to the "prevention member" of the present invention and is formed, for example, from a resin in the shape of a long plate. The I-hook 34 is positioned with its longitudinal direction in the front-to-rear direction and its plate thickness direction in the left-to-right direction, and is sewn to the lower extension 32B of the locking part 32 at a stitching portion S shown in Figure 6. The I-hook 34 is positioned below the top wall 50A and is sandwiched together with the lower extension 32B between the vertical wall 48A and the hanging wall 50C.

[0033] When the periphery of the operating lever member 46 on the cover body 30 is pulled by the occupant, causing the locking portion 32 to attempt to slip out of the gap between the escutcheon 50 and the back pad 24, the I-hook 34 engages with the top wall portion 50A of the escutcheon 50 from below (abutting via the horizontal portion 32A of the locking portion 32). The gap between the top wall portion 50A of the escutcheon 50 and the vertical wall portion 48A of the case 48 is set to be equal to the thickness of the locking portion 32, and the downward extension portion 32B of the locking portion 32 to which the I-hook 34 is sewn cannot pass through the gap between the top wall portion 50A and the vertical wall portion 48A. This prevents the locking portion 32 from slipping out of the gap between the escutcheon 50 and the back pad 24.

[0034] In the vehicle seat 10 configured as described above, the back of an occupant seated on the seat cushion 12 is supported by the seat back 14R. A cover body 30 of a trim cover 28 is placed over the back pad 24 of the seat back 14R. A locking portion 32 provided on a terminal portion 30A of the cover body 30 is disposed in the gap between the back pad 24 and an escutcheon 50 of an operating lever member 46 provided at the shoulder of the seat back. An I-hook 34 attached to the locking portion 32 engages with the escutcheon 50 to prevent the locking portion 32 from slipping out of the gap. This prevents the back pad 24 and the back frame 20 from being seen between the terminal portion 30A of the cover body 30 and the operating lever member 46, even if the cover body 30 is pulled by the occupant.

[0035] Furthermore, since the above-mentioned I-hook 34 is formed in a plate shape and is positioned between the escutcheon 50 and the back pad 24, the locking operation is easier than in a configuration in which, for example, a retaining member attached to the locking portion 32 is inserted into a hole formed in the back frame 20 or the like and locked, which makes it easier to manufacture the vehicle seat 10.

[0036] Furthermore, since the I-hook 34 is sewn to the engaging portion 32 of the cover body 30, the I-hook 34 can be attached more easily than in a configuration in which the I-hook 34 is glued to the engaging portion 32, for example.

[0037] Furthermore, the I-hook 34 is sandwiched together with the locking portion 32 between the vertical wall portion 48A of the case 48 of the operating lever member 46 and the hanging wall portion 50C of the escutcheon 50 of the operating lever member 46. This allows the locking portion 32 to be securely locked between the vertical wall portion 48A and the hanging wall portion 50C.

[0038] In the above embodiment, the case 48 of the operating lever member 46 has the vertical wall portion 48A, but this is not limiting and the vertical wall portion 48A may be omitted. In this case, for example, a part of the bracket 22 may be interposed between the I-hook 34 and the back pad 24.

[0039] In addition, in the above embodiment, the I hook 34 is configured to be sewn to the engaging portion 32 of the cover main body 30, but this is not limited to this, and the I hook 34 may be attached to the engaging portion 32 by means other than sewing.

[0040] Furthermore, in the above embodiment, the case where the plate-shaped I hook is the retaining member has been described, but the shape of the retaining member can be changed as appropriate.

[0041] 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]
