Abstract

A vehicle seat back has first and second support members each having a central web and a rear wall extending therefrom. A seat base is operably connected with the first and second support members. A recliner heart operably connects the seat base with the first and second support members. A shear center of the first and second support members extends along an inside corner connection of the central web and the rear wall of the first and second support members and into the seat base.

First claim

What is claimed is:

1. A vehicle seat back comprising:
first and second support members each having a central web and a rear wall extending therefrom;
a seat base disposed below the first and second support members; and
a recliner heart operably connecting the seat base with the first and second support members, wherein a shear center of the first and second support members extends along an inside corner connection of the central web and the rear wall of the first and second support members and into the seat base.

2. The vehicle seat back of claim 1 , wherein the rear wall includes a groove that extends along the longitudinal extent of the rear wall.

3. The vehicle seat back of claim 1 , comprising:
a support flange that extends from an inside edge of the rear wall.

4. The vehicle seat back of claim 1 , comprising:
an upper cross support and a lower cross member which together with the first and second support members define an impact zone pocket.

5. The vehicle seat back of claim 1 , comprising:
a front wall that extends from the central web, the front wall having a front lip extending therefrom.

6. The vehicle seat back of claim 5 , wherein the front wall includes a substantially convex construction and the rear wall includes a substantially concave construction.

7. The vehicle seat back of claim 1 , wherein a top portion of the vehicle seat back includes a scalloped upper cross support.

8. The vehicle seat back of claim 1 , wherein a bottom portion of the vehicle seat back includes a lower cross member that wraps around a bottom portion of the first and second support members.

9. A vehicle seat back comprising:
first and second support members having a central web;
a scalloped upper cross member extending between the first and second support members; and
a rear wall extending along the central web, wherein lateral load forces applied to the vehicle seat back result in a shear center that extends along an inside corner defined by the connection of the rear wall and the central web and into a seat base.

10. The vehicle seat back of claim 9 , wherein the rear wall includes a groove that extends along the longitudinal extent of the rear wall.

11. The vehicle seat back of claim 9 , comprising:
a support flange that extends from an inside edge of the rear wall.

12. The vehicle seat back of claim 9 , wherein the central web includes a recessed portion.

13. The vehicle seat back of claim 9 , comprising:
a front wall that extends from the central web, the front wall having a front lip extending therefrom.

14. The vehicle seat back of claim 9 , wherein the front wall includes a substantially convex construction and the rear wall includes a substantially concave construction.

15. The vehicle seat back of claim 9 , wherein the first and second support members are operably connected with a scalloped lower cross member.

16. The vehicle seat back of claim 9 , wherein a bottom portion of the vehicle seat back includes a lower cross member that wraps around a bottom portion of the vehicle seat back.

17. A vehicle seat back comprising:
an upper cross member having a scalloped forward portion;
a lower cross member having a scalloped rearward portion; and
first and second support members connected by the upper and lower cross members and having a central web connected with a recliner heart, wherein lateral forces applied to the vehicle seat back result in a shear center that extends along an inside corner connection of the central web and a rear wall of the first and second support members and into a seat base.

18. The vehicle seat back of claim 17 , wherein the rear wall includes a groove that extends along the longitudinal extent of the rear wall.

19. The vehicle seat back of claim 17 , comprising:
an upper cross support and a lower cross member which together with the first and second support members define an impact zone pocket.

20. The vehicle seat back of claim 17 , comprising:
a front wall that extends from the central web, the front wall having a front lip extending therefrom.
