Abstract

An automotive seat assembly including a seat bottom and a seat back pivotally attached to the seat bottom. The seat back includes a rigid seat back frame supporting a contoured foam cushion encapsulated in a trim cover material. A semi-rigid back panel, having a main body portion and a pair of side portions, is mounted to the rear of the seat back to conceal the rear surface of the seat back frame. A pair of guide members are mounted to the seat back frame and a pair of positioners are mounted to the back panel for alignment and engagement with the guide members. The positioners have an opening for sliding around the guide members as the back panel is positioned onto the seat back frame. A fastening member is also secured to the seat back frame. The back panel also includes a receiving portion mounted adjacent the bottom of the back panel for encapsulating the fastening member which closes any gaps formed between the bottom of the back panel and the seat back frame. A trim retention device is attachcd to a portion of the trim cover material. A receiving bracket is also mounted to the back panel for engaging the trim retention device to secure the trim cover to the panel. The engagement of the receiving bracket and the trim retention device prevents separation of the trim cover material and the foam cushion from the seat frame.

Claims

1. An automotive seat assembly comprising:

a seat back defining an occupant back support and including a seat back frame having a front surface, a rear surface, and first and second side surfaces;

a cushion supported on said front surface of said seat back frame;

a trim cover material covering said seat cushion and at least a portion of each of said first and second side surfaces of said seat back frame;

a semi-rigid back panel having a substantially planar main body portion and a pair of substantially parallel side portions projecting substantially perpendicular to said main body portion;

at least one guide member projecting from one of a side surface of said seat back frame or a complementary side portion of said back panel in a first direction;

at least one positioner projecting from the other of said side surface of said seat back frame or said complemented side portion of said back panel in a second direction opposite said first direction and engaging said guide member, said positioner including a slot having a downwardly facing opening slidably receiving said guide member as said back panel is positioned onto said seat back frame until said positioner secures said back panel to said seat back and said guide member is retained in said slot so that said main body of said back panel covers at least a portion of said rear surface of said seat back frame and so that said side portions of said back panel cover said trim cover material on said side surfaces of said seat back frame.

2. An assembly as set forth in claim 1 wherein said guide member includes a support post extending from one of said seat back frame or said back panel to a distal end.

3. An assembly as set forth in claim 2 wherein said guide member includes a retaining flange extending from said distal end of said support post.

4. An assembly as set forth in claim 3 wherein said retaining flange at least partially overlays said support post.

5. An assembly as set forth in claim 1 wherein said positioner includes a substantially J-shaped catch defining said opening for slidably receiving and engaging said guide member.

6. An assembly as set forth in claim 5 wherein said J-shaped catch includes a rim portion for creating a slot within said catch, said guide member slides within said slot and said rim portion at least partially surrounds said guide member.

7. An assembly as set forth in claim 6 wherein said J-shaped catch has a long leg and a short leg with said guide member secured between said long and short legs.

8. An assembly as set forth in claim 1 wherein said guide member extends from said seat back frame and said positioner extends from said back panel.

9. An assembly as set forth in claim 8 wherein said seat back frame side surfaces are substantially parallel to each other, and a guide member extends perpendicularly from each of said side surfaces of said seat back frame.

10. An assembly as set forth in claim 9 wherein a positioner is mounted to an inner surface of each of said side portions of said back panel for alignment with said guide members extending from said side surfaces of said seat back frame.

11. An assembly as set forth in claim 1 including

a fastening member having an outwardly projecting portion and an engagement portion, wherein said engagement portion is secured to said seat back frame;

and

said back panel includes a receiving portion mounted adjacent a bottom of said back panel for at least partially encapsulating said projecting portion of said fastening member after said back panel is secured to said seat back frame, thus positioning at least a portion of said bottom of said back panel adjacent said seat back frame.

12. An assembly as set forth in claim 11 wherein said receiving portion includes an annular sleeve having an inner surface and an outer surface with said inner surface of said annular sleeve engaging and completely surrounding said projecting portion of said fastening member.

13. An assembly as set forth in claim 11 wherein said receiving portion includes a U-shaped locator having an inner surface and an outer surface with said inner surface of said U-shaped locator engaging and at least partially surrounding said projecting portion of said fastening member.

14. An assembly as set forth in claim 1 including

a trim retention device attached to a portion of said trim cover material;

and

said back panel includes a receiving bracket engaging said trim retention device and securing said trim cover material to said back panel, said engagement of said receiving bracket and said trim retention device preventing separation of said trim cover material and said cushion from said seat back frame.

15. An assembly as set forth in claim 14 wherein said trim retention device comprises a thin plate fixedly attached to a distal end of said trim cover material.
