Abstract

A vehicle seat assembly having a seat bottom that includes first and second side frame members and a front cushion module. The front cushion module has a support wire and a cushion. The support wire has first and second ends that are disposed proximate the front end of the first and second side frame members, respectively. The cushion receives and is supported by the support wire.

Claims

1. A vehicle seat assembly comprising:

a seat back pivotally disposed on a seat bottom, the seat bottom including;

first and second side frame members that each have a rear end disposed proximate the seat back and a front end disposed opposite the rear end; and

a front cushion module including;

a support wire having first and second ends fixedly disposed on the front ends of the first and second side frame members, respectively; and

a cushion that receives and is supported by the support wire, wherein the cushion includes a front surface disposed at a front of the seat bottom, a top surface disposed at a top of the cushion, a bottom surface disposed opposite the top surface, and a set of notches that extends from the front surface and extend from the bottom surface toward the top surface of the cushion such that the members of the set of notches do not extend to the top surface and are spaced apart from each other and wherein the support wire extends through each member of the set of notches; and

a trim cover assembly that is attached to the support wire within members of the set of notches.

2. The vehicle seat assembly of claim 1 wherein the seat bottom is disposed on a track assembly that facilitates fore-aft positioning of the vehicle seat assembly, and wherein the first and second side frame members are part of a seat height adjuster that facilitates positioning of the seat bottom with respect to the track assembly.

3. The vehicle seat assembly of claim 2 wherein the seat height adjuster further includes first and second front linkages that are pivotally disposed on the first and second side frame members, respectively, along a pivot axis, wherein the front cushion module is completely disposed forwardly of the pivot axis.

4. The vehicle seat assembly of claim 1 wherein the seat bottom further comprises a suspension mat disposed between the first and second side frame members and between the front cushion module and the seat back, wherein the front cushion module is disposed forwardly and spaced apart from the suspension mat.

5. The vehicle seat assembly of claim 1 wherein the cushion further comprises a back surface disposed opposite the front surface and first and second side surfaces that extend from the front surface to the back surface, wherein the back surface is disposed between the first and second side frame members and located forwardly of first and second front linkages that are pivotally disposed on the first and second side frame members, respectively.

6. The vehicle seat assembly of claim 1 wherein each member of the set of notches is disposed substantially parallel to each other.

7. The vehicle seat assembly of claim 1 further comprising a set of attachment features, wherein each member of the set of attachment features engages the support wire within a corresponding member of the set of notches to secure the trim cover assembly to the support wire.

8. A vehicle seat assembly comprising:

a seat back pivotally disposed on a seat bottom, the seat bottom having;

a seat track assembly;

first and second side frame members that are disposed along opposite sides of the seat bottom and pivotally disposed on the seat track assembly, the first and second side frame members each having a rear end disposed proximate the seat back and a front end disposed opposite the rear end; and

a front cushion module including;

a support wire having first and second ends fixedly disposed on the front ends of the first and second side frame members, respectively; and

a cushion that receives and is supported by the support wire, wherein the cushion has a set of notches that extend from a front surface of the cushion toward a back surface of the cushion disposed opposite the front surface and from a bottom surface of a cushion that faces toward the seat track assembly toward a top surface of the cushion that is disposed opposite the bottom surface such that the set of notches do not extend to the top surface or the back surface, wherein the support wire extends through the cushion and through the set of notches such that the support wire is spaced apart from the cushion within each member of the set of notches; and

a cross member disposed in the cushion, wherein the cross member is fixedly disposed on the first and second side frame members.

9. The vehicle seat assembly of claim 8 wherein the cross member is spaced apart from the support wire.

10. The vehicle seat assembly of claim 8 wherein the cross member includes first and second flanges that are disposed along a top surface of the first and second side frame members, respectively.

11. The vehicle seat assembly of claim 10 wherein a first end of the support wire is fixedly mounted to the first side frame member below the first flange.

12. The vehicle seat assembly of claim 8 wherein the seat bottom further comprises a suspension mat disposed between the first and second side frame members, and wherein the cross member further comprises a set of holes that are spaced apart from each other and that each receive the suspension mat.

13. The vehicle seat assembly of claim 12 wherein the cushion further comprises a set of suspension mat notches, wherein each member of the set of suspension mat notches is aligned with and receives a member of the set of holes in the cross member.

14. The vehicle seat assembly of claim 12 wherein the set of holes is disposed below first and second flanges of the cross member that engage a top surface of the first and second side frame members, respectively.

15. A vehicle seat assembly comprising:

a seat back pivotally disposed on a seat bottom, the seat bottom having;

a seat bottom frame that includes;

first and second side frame members that include a rear end disposed proximate the seat back and a front end disposed opposite the rear end; and

a frame cross member that extends between the first and second side frame members; and

a seat height adjuster that includes;

first and second rear linkages that are pivotally disposed on the frame cross member; and

first and second front linkages that are pivotally disposed on the first and second side frame members, respectively, wherein the first and second front linkages are disposed on the first and second side frame members between the front end and the rear end of the first and second side frame members, respectively; and

a front cushion module that includes;

a support wire having first and second ends that engage the front end of the first and second side frame members, respectively; and

a cushion that receives and is supported by the support wire, wherein the cushion includes a front surface and a set of notches that extend from the front surface, wherein the support wire extends through each member of the set of notches; and

a trim cover that includes a set of attachment features that engage the support wire to couple the trim cover to the seat bottom.

16. The vehicle seat assembly of claim 15 and wherein each member of the set of attachment features is coupled to the support wire within a corresponding member of the set of notches.

17. The vehicle seat assembly of claim 15 wherein the cushion further comprises a back surface disposed opposite the front surface and first and second side surfaces that extend from the front surface to the back surface, wherein the back surface is disposed between the first and second side frame members and located forwardly of the first and second front linkages.

18. The vehicle seat assembly of claim 17 wherein the front cushion module includes a cross member that is disposed in the cushion and that extends from the back surface toward the front surface, wherein the cross member is fixedly disposed on the first and second side frame members.

19. The vehicle seat assembly of claim 18 wherein the cross member is disposed above the set of notches.

20. The vehicle seat assembly of claim 15 wherein the cushion is expanded polypropylene (EPP) foam.
