[Technical Field]
[0001] The present invention relates to a padding member and a vehicle seat. [Background technology]
[0002] The following Patent Document 1 discloses a gap concealing structure for a rear seat in which a cover of the same type as the cover is sewn to the seat cushion side in a bag-like shape with some slack, thereby forming a gap concealer that conceals the gap and maintains an aesthetic appearance. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 6-81820 Summary of the Invention [Problem to be solved by the invention]
[0004] Incidentally, the configuration described in Patent Document 1 is useful from the viewpoint of maintaining the aesthetic appearance of vehicle seats such as rear seats, but it requires that a covering material of the same type as the cover that covers the pad be sewn to the seat cushion.
[0005] In consideration of the above, an object of the present invention is to prevent the aesthetic appearance from being impaired by gaps around the pad member without sewing on a separate cover material. [Means for solving the problem]
[0006] The pad member of the first embodiment is formed in a block shape and comprises a pad body that supports the body of a seated occupant, a skin material that covers the pad body and has an excess portion that can form a gap between it and the pad body, and a biasing portion that is provided between the excess portion and the pad body and biases the excess portion toward the opposite side from the pad body.
[0007] In the pad member of the first aspect, the pad main body is covered with a skin material. Here, the skin material has an excess portion that can form a gap between it and the pad main body. In addition, a biasing portion is provided between the excess portion and the pad main body. This biasing portion biases the excess portion of the skin material toward the opposite side of the pad main body. As a result, the excess portion of the skin material protrudes toward the opposite side of the pad main body. Then, the protruding excess portion biased by the biasing portion can close or reduce the gap between the pad member and an adjacent member. This makes it possible to prevent the gap around the pad member from damaging the appearance.
[0008] The pad member of the second aspect is the pad member of the first aspect, further comprising a locking member having a skin locking portion to which a portion of the skin is locked and a pad body locking portion to which the pad body is locked, and the biasing portion is formed integrally with the locking member.
[0009] In the pad member of the second aspect, the biasing portion is formed integrally with a locking member having a cover material locking portion and a pad body locking portion. In this configuration, by locking the pad body locking portion of the locking member to the pad body while a part of the cover material is locked to the cover material locking portion of the locking member, the cover material can be attached to the pad body and the excess length can be protruded by the biasing portion.
[0010] The pad member of the third aspect is the pad member of the second aspect, wherein the end of the urging portion opposite the upholstery material engaging portion and the pad main body engaging portion is a bulging portion that bulges out toward the upholstery material engaging portion and the pad main body engaging portion of the urging portion.
[0011] In the pad member of the third embodiment, compared to a configuration in which the end of the urging portion opposite the upholstery material engaging portion and the pad main body engaging portion does not form a bulge portion, it is possible to suppress a local increase in contact pressure between the urging portion and the upholstery material.
[0012] A fourth aspect of the vehicle seat comprises a seat body having a seat cushion that supports the buttocks of a seated occupant from the underside of the seat and a seat back that supports the back of the seated occupant from the rear side of the seat, a cover member attached to the seat body and covering part of the seat body, and a pad member of any one of the first to third aspects that forms part of the seat cushion and the seat back, and the excess portion is arranged opposite the cover member.
[0013] In the vehicle seat of the fourth aspect, the excess length of the upholstery material that protrudes when biased by the biasing portion can close or reduce the gap between the pad member and the cover member, thereby preventing the gap around the pad member from damaging the aesthetic appearance. [Effects of the Invention]
[0014] In the present invention, it is possible to prevent the appearance from being spoiled by gaps around the pad member without sewing on a separate cover material. [Brief explanation of the drawings]

FIG. [Figure 3] 3 is a cross-sectional view corresponding to FIG. 2, showing a seat cushion and a cover member of another type. DETAILED DESCRIPTION OF THE INVENTION
[0016] A vehicle seat 10 according to an embodiment of the present invention will be described with reference to Figures 1 and 2. Note that the arrows FR, UP, LH, and RH shown in the figures indicate the front side, upper side, left side, and right side of the seat as seen by an occupant seated in the vehicle seat 10, respectively. Hereinafter, when the terms "front-rear," "up-down," and "left-right" are used in the description, they will refer to the front-rear direction of the seat, the up-down direction of the seat, and the left-right direction of the seat, unless otherwise specified. The left-right direction of the seat coincides with the width direction of the seat.
[0017] 1, a vehicle seat 10 of this embodiment includes a seat cushion 12 that supports the buttocks of a 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 and the seat back 14 form a seat main body 18. The vehicle seat 10 also includes a lifting mechanism (not shown) that supports the seat main body 18 so that it can be displaced in the up and down direction, a sliding mechanism (not shown) that supports the seat main body 18 so that it can be displaced in the front and rear direction, and a cover member 20 that covers a portion of the seat main body 18.
[0018] The seat cushion 12 is configured by attaching a cushion pad member 22 as a pad member to a cushion frame (not shown) that forms the skeleton of the seat cushion 12. The seat back 14 is also formed by attaching a back pad member 24 as a pad member to a back frame (not shown) that forms the skeleton of the seat back 14.
[0019] As shown in Figures 1 and 2, the cushion pad member 22 includes a pad main body 26 formed into a block shape of a predetermined shape using urethane or the like, a skin material 28 covering the pad main body 26, and a locking member 30.
[0020] As shown in Fig. 1, the pad main body 26 is configured to deform when a load from a seated occupant is input, thereby supporting the buttocks of the seated occupant. Specifically, the pad main body 26 includes a main portion 32 that forms a central portion in the seat width direction, and a pair of left and right side support portions 34 that form both side portions in the seat width direction. In addition, as shown in Fig. 2, the pad main body 26 includes an outer protrusion 36 that protrudes downward from the left side support portion 34 (see Fig. 1), which is on the outer side in the seat width direction.
[0021] The upholstery material 28 is formed into a sheet shape using leather or cloth. The upholstery material 28 of this embodiment includes a first covering portion 40 that covers the outer surface of the outer convex portion 36 in the seat width direction, and a second covering portion 42 that covers the lower surface 36A of the outer convex portion 36. The second covering portion 42 extends from the lower end of the first covering portion 40 toward the inner side in the seat width direction, and an inner end 42A of the second covering portion 42 in the seat width direction is engaged by sewing to an upholstery material engaging portion 52 of the engaging member 30 (described later). The member indicated by the reference numeral 46 is a sewing portion that sews the inner end 42A of the second covering portion 42 in the seat width direction to the upholstery material engaging portion 52 of the engaging member 30. Here, the second covering portion 42 of this embodiment has an excess portion 42B that is capable of forming a gap 48 between the second covering portion 42 and the lower surface 36A of the outer convex portion 36. The inner surface of the outer protrusion 36 in the seat width direction is in contact with the cushion side frame 38 .
[0022] The locking member 30 is made of a resin material or the like. The locking member 30 includes a pad main body locking portion 50 formed in a generally U-shaped cross section with an open upper side, and a cover material locking portion 52 extending upward from the upper end of the pad main body locking portion 50 on the outer side in the seat width direction. The cross section from the pad main body locking portion 50 to the cover material locking portion 52 is generally J-shaped.
[0023] As an example, the pad main body engaging portion 50 is engaged with an engaged portion 54 provided on the cushion side frame 38. The pad main body engaging portion 50 is provided with an engaging protrusion 50A for maintaining the engaged state between the pad main body engaging portion 50 and the engaged portion 54.
[0024] The outer end 42A of the second covering portion 42 in the seat width direction is fastened to the inner surface of the cover fastening portion 52 in the seat width direction by sewing.
[0025] The locking member 30 also has a biasing portion 56 that protrudes from the lower end of the pad main body locking portion 50 downward toward the seat and inward in the seat width direction. The pad main body locking portion 50 side of the biasing portion 56 is formed as a plate-shaped base plate portion 56A. The opposite side of the biasing portion 56 from the pad main body locking portion 50 is formed as a bulging portion 56B that bulges out relative to the base plate portion 56A. An outer peripheral surface 56C of the bulging portion 56B is a gently curved cylindrical surface.
[0026] The biasing portion 56 described above is disposed in the gap 48 formed between the lower surface 36A of the outer convex portion 36 and the excess portion 42B of the second covering portion 42. When the biasing portion 56 is disposed in this gap 48, the biasing portion 56 is deformed upward relative to the pad main body engaging portion 50. Then, due to the force of the biasing portion 56 attempting to return downward relative to the pad main body engaging portion 50, the excess portion 42B of the second covering portion 42 is pressed downward and protrudes.
[0027] Further, a cover member 20 is provided below the left end 22A of the cushion pad member 22, covering a portion of the seat cushion frame that constitutes a part of the seat cushion 12. The cover member 20 has a top wall portion 20A that extends in the left-right and front-rear directions, with the thickness direction being the up-down direction. The excess length portion 42B of the second covering portion 42 that protrudes downward by being pressed by the biasing portion 56 of the locking member 30 abuts against the top wall portion 20A of the cover member 20.
[0028] (Actions and Effects of This Embodiment) Next, the operation and effects of this embodiment will be described.
[0029] 1 and 2 , in the vehicle seat 10 of the present embodiment described above, the excess portion 42B of the second covering portion 42, which is pressed by the biasing portion 56 of the locking member 30 to protrude downward, abuts against the top wall portion 20A of the cover member 20. As a result, the excess portion 42B of the second covering portion 42 closes the gap 58 formed between the left end portion 22A of the cushion pad member 22 and the top wall portion 20A of the cover member 20. This prevents the gap 58 formed between the left end portion 22A of the cushion pad member 22 and the top wall portion 20A of the cover member 20 from impairing the aesthetic appearance of the vehicle seat 10. In this way, in the present embodiment, it is possible to prevent the gap 58 from impairing the aesthetic appearance of the vehicle seat 10 without sewing a separate upholstery material to the second covering portion 42 or the like to close the gap 58.
[0030] In this embodiment, the biasing portion 56 is formed integrally with the locking member 30 having the cover material locking portion 52 and the pad main body locking portion 50. In this configuration, by locking the pad main body locking portion 50 of the locking member 30 to the locked portion 54 with the seat width direction outer end 42A of the second covering portion 42 of the cover material 28 locked to the cover material locking portion 52 of the locking member 30, the cover material 28 can be attached to the pad main body 26 and the excess length portion 42B can be protruded downward by the biasing portion 56.
[0031] In this embodiment, the side of the urging portion 56 opposite the pad main body engaging portion 50 is a bulging portion 56B that bulges out relative to the base portion 56A, and the outer peripheral surface 56C of the bulging portion 56B is a gently curved cylindrical surface. This makes it possible to prevent local increases in contact pressure between the urging portion 56 and the cover material 28, compared to a configuration in which the end of the urging portion 56 opposite the pad main body engaging portion 50 does not have the bulging portion 56B of the above configuration.
[0032] In the above-described example, the bulge portion 56B is provided on the side of the urging portion 56 opposite the pad main body engaging portion 50, but the present invention is not limited to this. Whether or not to provide the bulge portion 56B and the shape of the bulge portion 56B may be determined appropriately taking into consideration the shape of the excess length portion 42B when pressed by the urging portion 56, etc.
[0033] In addition, in the present embodiment, an example has been described in which the biasing portion 56 is formed integrally with the locking member 30 having the cover material locking portion 52 and the pad main body locking portion 50, but the present invention is not limited to this. For example, a configuration may be adopted in which a member that functions only as the biasing portion 56 is provided as a separate member from the locking member 30.
[0034] Furthermore, in the present embodiment, an example has been described in which the excess portion 42B of the second covering portion 42, which protrudes downward as a result of being pressed by the biasing portion 56 of the locking member 30, abuts against the top wall portion 20A of the cover member 20. However, the present invention is not limited to this. For example, the excess portion 42B of the second covering portion 42, which protrudes downward as a result of being pressed by the biasing portion 56 of the locking member 30, may be spaced apart from the top wall portion 20A of the cover member 20. Even in this configuration, the gap 58 formed between the left end portion 22A of the cushion pad member 22 and the top wall portion 20A of the cover member 20 is reduced (narrowed) by the excess portion 42B of the second covering portion 42. This makes it possible to prevent the gap 58 formed between the left end portion 22A of the cushion pad member 22 and the top wall portion 20A of the cover member 20 from impairing the aesthetic appearance of the vehicle seat 10.
[0035] 3, a configuration may be adopted in which a flange portion 20B is provided that bends and extends upward from an outer end portion in the seat width direction of the top wall portion 20A of the cover member 20. By providing this flange portion 20B, the gap 58 formed between the left end portion 22A of the cushion pad member 22 and the top wall portion 20A of the cover member 20 becomes less visible. This further prevents the gap 58 formed between the left end portion 22A of the cushion pad member 22 and the top wall portion 20A of the cover member 20 from impairing the aesthetic appearance of the vehicle seat 10.
[0036] Furthermore, the configuration of the present invention described above can be applied not only to closing or reducing the gap 58 formed between the cushion pad member 22 and the cover member 20, but also to closing or reducing the gap formed between the cushion pad member 22 and other members. Furthermore, the configuration of the present invention described above can also be applied to the seat back 14 side.
[0037] 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]
