Abstract

A seat assembly (10) of the type utilized in automotive vehicles for supporting an occupant including a track with upper (18) and lower (20,20'"'"') rails, the upper rail (18) being an extruded C-shaped channel having side walls (26 and 28) and a top (34) extending therebetween. The upper rail (18) is characterized by a retaining wing (30) integral with and extending downwardly (30) and upwardly (32) from and in spaced relationship to the adjacent side wall (26). A tab (40) extends outwardly from the first side (26) and forms an extension of the top (34). A suspension (50) for supporting a cushion (54) is attached to a pair of spaced members (18) by suspension hooks (52) which are hooked over the tabs (40). A fabric cover (56) is disposed over the cushion and is attached to the members (18) by trim hooks which are likewise hooked over the wings (30).

Claims

1. A seat assembly of the type utilized in automotive vehicles for supporting an occupant, said assembly comprising:

a seat frame defining an occupant sitting area;

a back frame defining an occupant back supporting area;

at least a section of one of said frames having oppositely facing parallel and symmetrical first and second sides wherein said section is a channel member as viewed in cross-section with a top extending between said first and second sides;

a retaining wing integral with and extending outwardly from said first side to a distal end spaced from said first side;

a tab integral with said top extending outwardly from said first side and forming a linear extension of said top; and

including trim material and at least one trim hook attached to said trim material and hooked over said wing.

2. An assembly as set forth in claim 1 including a pair of said channel members spaced from one another on opposite sides of said seat assembly with said tabs extending outwardly from said sides, a suspension extending between said spaced channel members, and at least one suspension hook attached to said suspension on each side and hooked over said tab of the adjacent channel member.

3. An assembly as set forth in claim 2 including mounts secured to said lower rail and extending downwardly for securing said seat assembly to the structure of a vehicle.

4. An assembly as set forth in claim 3 including roller elements disposed between said upper and lower rails to facilitate the sliding movement between said rails.

5. An assembly as set forth in claim 1 wherein said channel defines the upper rail of a seat track, said seat track including a lower rail slidably disposed and retained in said upper rail.

6. An assembly as set forth in claim 1 including a lip extending along said distal end of said wing and on the inward side of said wing toward the adjacent side.

7. An assembly as set forth in claim 1 wherein said first side defines a plane and includes a recess and said wing extends from said first side along the plane of said side and defines one wall of said recess.

8. An assembly as set forth in claim 7 wherein said channel member is symmetrical to include a pair of said recesses and a pair of said wings extending in opposite directions from opposite sides of said channel.

9. A seat assembly of the type utilized in automotive vehicles for supporting an occupant, said assembly comprising:

a seat frame defining an occupant sitting area;

a back frame defining an occupant back supporting area;

at least a section of one of said frames having oppositely facing first and second sides;

a retaining wing integral with and extending from said first side to a distal end spaced from said first side;

said side defining a plane and including a recess, said wing extending from said side along the plane of said side and defining one wall of said recess; and

said section is symmetrical to include a pair of said recesses and a pair of said wings extending in opposite directions from opposite sides of said section.

10. A seat assembly of the type utilized in automotive vehicles for supporting an occupant, said assembly comprising:

a seat frame defining an occupant sitting area;

a back frame defining an occupant back supporting area;

at least one of said frames including a pair of channel members spaced from one another on opposite sides of said seat assembly;

each of said channel members including oppositely facing parallel and symmetrical first and second sides with a top extending between said sides;

a retaining wing integral with and extending outwardly from said first side to a distal end spaced from said side;

a tab integral with said top extending outwardly from said first side and forming a linear extension of said top;

trim material extending between said spaced channel members and having at least one trim hook attached to said trim and hooked over said wing on each channel member; and

a suspension extending between said spaced channel members and having at least one suspension hook attached to said suspension on each side and hooked over said tab of said respective adjacent channel member.
