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

[0002] The following Patent Document 1 discloses a back pad constituting a part of a vehicle seat and a seat cover attached to the back pad. The back pad described in this document includes a main pad constituting the center part of the back pad in the left-right direction and a side pad constituting both sides of the back pad in the left-right direction. The back pad also includes a shoulder part integrally formed on the upper part of the side pad. The shoulder part is shaped like a horn so as to be higher than the main pad. The seat cover described in this document also includes a bag-shaped cover body including a main part covering the main pad and a side part covering the side pad. A shoulder piece is provided at a portion of the cover body corresponding to the shoulder part.

[0003] The shoulder piece includes a plate-shaped face contact member, and a support member and a clamping member that sandwich the face contact member from both sides. The support member is a part of the cover body, and the clamping member is a fixing means that clamps and fixes the face contact member between the support member and the clamping member. The shoulder piece is formed by fixing the face contact member to the clamping member with double-sided adhesive tape, overlapping the clamping member on the support member in this fixed state, and sewing together the peripheral portions of the support member and the clamping member. Since the face contact member is made of a hard material, it is possible for the face contact member to shape and maintain the shape of the shoulder portion, and to prevent the shoulder portion from being crushed.

[0004] [Patent Document 1] JP 2010-268873 A Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, the configuration described in the above Patent Document 1 is useful from the viewpoint of preventing crushing of protruding parts of the seat pad, such as the shoulder parts, but requires work such as temporarily fixing a shape-retaining plate, such as a face-contact member, with double-sided adhesive tape, complicating the manufacturing process.

[0006] In consideration of the above, an object of the present invention is to provide a seat cover and a vehicle seat that can cover a seat pad having a protruding portion while preventing the manufacturing process from becoming complicated. [Means for solving the problem]

[0007] The seat cover of a first aspect includes a first skin formed in a sheet shape and arranged on a base end side of a seat pad having a protrusion in a protruding direction of the protrusion, covering a portion of the seat pad; a second skin formed in a sheet shape and arranged on a tip end side of the protrusion in the protruding direction of the protrusion of the seat pad, covering a portion of the seat pad; a third skin formed in a sheet shape and arranged along the protrusion between the first skin and the second skin, with an end portion on the first skin side joined by sewing to the end portion of the first skin and an end portion on the second skin side joined by sewing to the end portion of the second skin, covering a portion of the seat pad; a back surface member formed in a sheet shape and arranged along the third skin on the seat pad side relative to the third skin, with an end portion on the second skin side joined by sewing to the end portion of the third skin; and a shape retention plate formed in a plate shape using a member harder than the third skin, inserted between the third skin and the back surface member, and with an end portion on the first skin side joined by sewing to the end portion of the third skin.

[0008] In the seat cover of the first aspect, the protruding portion of the seat pad at the base end side in the protruding direction is covered by the first skin. In addition, the protruding portion of the seat pad at the tip end side in the protruding direction is covered by the second skin. Furthermore, the protruding portion of the seat pad is covered by the third skin. In this way, the seat cover of the first aspect can cover the seat pad having the protruding portion. In addition, in the seat cover of the first aspect, a back member is provided on the seat pad side with respect to the third skin. The end of the back member on the second skin side is joined to the end of the third skin by sewing. In addition, in the seat cover of the first aspect, for example, the shape retention plate can be temporarily fixed to the third skin by inserting the shape retention plate between the third skin and the back member and joining the end of the shape retention plate on the first skin side to the end of the third skin by sewing. In this way, in the seat cover of the first aspect, it is possible to eliminate the need to use double-sided adhesive tape or the like when temporarily fixing the shape retention plate to the third skin. As a result, it is possible to suppress the manufacturing process from becoming complicated.

[0009] The seat cover of the second aspect is the seat cover of the first aspect, wherein the thickness of the back surface member is set to be thinner than the thickness of the third skin.

[0010] In the seat cover of the second aspect, the influence of the thickness of the back surface member on the appearance quality of the seat cover can be reduced.

[0011] The seat cover of a third aspect is the seat cover of the first or second aspect, wherein the thickness of the third skin is set to be thinner than the thickness of the first skin and the thickness of the second skin.

[0012] According to the seat cover of the third aspect, the total thickness of the third skin, the back surface member and the shape retention plate can be made close to the thickness of the first skin and the thickness of the second skin, thereby reducing the effect of providing the back surface member and the shape retention plate on the appearance quality of the seat cover.

[0013] The vehicle seat of the fourth aspect comprises a seat cushion that supports the buttocks of a seated occupant from the underside of the seat, a seat back that supports the back of the seated occupant from the rear side of the seat, a seat pad that forms part of the seat cushion or the seat back and has a protruding portion, and a seat cover of any one of the first to third aspects that covers the seat pad.

[0014] According to the vehicle seat of the fourth aspect, the seat pad having the protruding portion can be covered by the seat cover of any one of the first to third aspects. In addition, in the seat cover of any one of the first to third aspects, it is possible to eliminate the need to use a double-sided adhesive tape or the like when temporarily fixing the shape retention plate to the third skin. As a result, it is possible to prevent the manufacturing process from becoming complicated. Effect of the Invention

In addition, the end 42A of the third skin 42 on the second skin 40 side is joined by sewing to an end 40C of the second skin 40 on the inner side in the seat width direction, together with an end 44A of the back surface member 44 on the second skin 40 side.

[0030] (Actions and Effects of the Present Embodiment) Next, the operation and effects of this embodiment will be described.

[0031] 1 and 2, in the present embodiment described above, the back pad 22 having the protruding portion 34 can be covered by the back trim 24. When the back pad 22 is covered by the back trim 24, the lower end of the shape retention plate 46 and the lower end of the third skin 42 are disposed inside the groove 36. When the back pad 22 is covered by the back trim 24, the shape retention plate 46 is disposed along the inner surface of the protruding portion 34 in the seat width direction. This allows the shape of the protruding portion 34 to be maintained by the shape retention plate 46.

[0032] In addition, in the back trim 24 of this embodiment, the back surface member 44 is provided so that the seam allowance 48 between the second skin 40 and the third skin 42 is not disposed between the shape retention plate 46 and the third skin 42. This makes it possible to suppress deterioration of the appearance of the seat back 14 caused by the seam allowance 48 being disposed between the shape retention plate 46 and the third skin 42.

[0033] Furthermore, in the back trim 24 of this embodiment, the thickness T3 of the third skin 42 is set to be thinner than the thickness T1 of the first skin 38 and the thickness T2 of the second skin 40. This makes it possible to make the total thickness of the third skin 42, the back surface member 44, and the shape-retaining plate 46 closer to the thickness T1 of the first skin 38 and the thickness T2 of the second skin 40. This makes it possible to reduce the effect on the appearance quality of the back trim 24 caused by providing the back surface member 44 and the shape-retaining plate 46.

[0034] In the back trim 24 of this embodiment, the thickness T4 of the back surface member 44 is set to be thinner than the thickness T3 of the third skin 42. This makes it possible to reduce the effect of the thickness of the back surface member 44 on the appearance quality of the back trim 24.

[0035] The back trim 24 described above can be manufactured through the following procedure.

[0036] First, the end 44A of the back surface member 44 on the side of the second skin 40 and the end 42A of the third skin 42 on the side of the second skin 40 are joined by sewing. This sewn portion is referred to as a first sewn portion H1.
