Abstract

Provided is a vehicle seat that allows engagement holes for engaging an end part of the skin member to be provided without burdening the seat frame design. The seat cushion of the vehicle seat includes a frame structure, a support member supported by the frame structure within the frame structure to resiliently support an occupant, a pad provided on a proximal side of the frame structure and the support member, and a skin member covering the pad. The support member is provided with plurality of engagement portions engaging end parts of the skin member.

First claim

The invention claimed is:

1. A vehicle seat having a seat cushion and a seat back, the vehicle seat comprising:
a frame structure provided in the seat cushion and including a left and a right side member, and front and rear cross members connecting corresponding ends of the side members to each other;
a support member for supporting an occupant, the support member including a plate-like main body supported by the frame structure within the frame structure and extending substantially in parallel with the frame structure, a pair of inclined portion extending laterally outward from parts of lateral side edges of the main body with an upward inclination, a front mounting portion extending from a front edge of the main body to be engaged by the front cross member, and a rear mounting portion extending from a rear edge of the main body to be engaged by the rear cross member;
a pad provided on an upper side of the frame structure and the support member; and
a skin member covering the pad,
wherein each side part of a front part of the main body where the inclined portions are absent is provided with a shape differing in height between a front side and a rear side thereof in side view.

2. The vehicle seat according to claim 1 , wherein the shape of the front part is formed such that the front side is lower than the rear side in side view.

3. The vehicle seat according to claim 1 , wherein the left and right side edges of the front part of the main body are provided with flanges, respectively.

4. The vehicle seat according to claim 3 , wherein the flanges are each continuous at least over a fore and aft range in which a corresponding step formed by the shape extends.

5. The vehicle seat according to claim 3 , wherein the flanges of the front part of the main body project to the upper side, and
wherein laterally outer side edges of the inclined portions are provided with inclined portion flanges projecting to the lower side.

6. The vehicle seat according to claim 3 , the side edges formed with the flanges at least partly obliquely extend forward and laterally inward.

7. The vehicle seat according to claim 1 , wherein the fore and aft length of the front part is shorter than the fore and aft length of the inclined portions,
wherein the laterally outer edges of the front part are located laterally inward of the laterally outer edges of the inclined portions.

8. The vehicle seat according to claim 1 , wherein each lateral side edge of the front part is provided with a recess having a rear end defined by the corresponding shape.

9. The vehicle seat according to claim 1 , wherein a lateral length of the front edge of the front part is smaller than a lateral length of a rear edge of the front part, and the front mounting portion is at least partly located near lateral edges of the front part.

10. The vehicle seat according to claim 1 , further comprising:
a left and a right slide rail fixed to a vehicle floor and slidably supporting the frame structure in the fore and aft direction; and
a position sensor attached to at least one of the side members extending in the fore and aft direction to detect the position of the seat in the fore and aft direction with respect to the floor,
wherein at least one of the left and right side edges of the support member is formed with a side cut-out located between the corresponding inclined portion and the front part of the support member,
wherein a fore and aft position of the position sensor is within a range of the side cut-out in the fore and aft direction.

11. The vehicle seat according to claim 1 , wherein the front mounting portion comprises a plurality of front mounting pieces that are separated from each other in the lateral direction, and
wherein a part of the front edge of the main body where the front mounting pieces are absent is provided with a front notch having a smaller lateral width than a distance between two parts where adjacent front mounting pieces are connected to the front edge.

12. A method for manufacturing a vehicle seat having a seat cushion and a seat back, the method comprising steps of assembling the seat cushion and assembling the seat back,
wherein the step of assembling the seat cushion comprises the steps of:
preparing a frame structure provided in the seat cushion and including a left and a right side member, and front and rear cross members connecting corresponding ends of the side members to each other;
placing a support member for supporting an occupant on the frame, the support member including a plate-like main body supported by the frame structure within the frame structure and extending substantially in parallel with the frame structure, a pair of inclined portion extending laterally outward from parts of lateral side edges of the main body with an upward inclination, a front mounting portion extending from a front edge of the main body to be engaged by the front cross member, and a rear mounting portion extending from a rear edge of the main body to be engaged by the rear cross member;
providing a pad on an upper side of the frame structure and the support member; and
covering the pad by a skin member,

wherein each side part of a front part of the main body where the inclined portions are absent is provided with a shape differing in height between a front side and a rear side thereof in side view.

13. The method according to claim 12 , wherein the shape of the front part is formed such that the front side is lower than the rear side in side view.

14. The method according to claim 12 , wherein the left and right side edges of the front part of the main body are provided with flanges, respectively.

15. The method according to claim 14 , wherein the flanges are each continuous at least over a fore and aft range in which a corresponding step formed by the shape extends.

16. The method according to claim 14 , wherein the flanges of the front part of the main body project to the upper side, and
wherein laterally outer side edges of the inclined portions are provided with inclined portion flanges projecting to the lower side.

17. The method according to claim 14 , the side edges formed with the flanges at least partly obliquely extend forward and laterally inward.

18. A method for manufacturing a vehicle seat having a seat cushion and a seat back, the method comprising the steps of assembling the seat cushion and assembling the seat back,
wherein at least one of the steps of assembling the seat cushion and assembling the seat back comprises the steps of:
preparing a frame structure;
placing a support member on the frame structure, wherein the support member is supported by the frame structure within the frame structure to support an occupant;
providing a pad on a proximal side of the frame structure and the support member; and
covering the pad by a skin member,

the support member including a plurality of engagement portions engaging end part of the skin member,
wherein the support member is formed in a plate shape, the engagement portions each comprise an engagement hole consisting of a through hole formed in the support member, the end part of the skin member being provided with a hook passed through the corresponding engagement hole from a distal side thereof to a proximal side thereof to engage a peripheral edge part of the engagement hole,
wherein the support member is provided with an inclined portion that extends outward in a lateral direction with respect to the locking portion, the inclined portions is inclined so that a laterally outside edge of the inclined porti
