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 member and a cushion. The support member 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 member and has a front end. The vehicle seat assembly may have an actuator cooperable with the support member for tilting the front end of the cushion relative to the frame members.

First claim

What is claimed is:

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 member having first and second ends disposed proximate the front end of the first and second side frame members, respectively;
a front cushion supported by the support member, and the front cushion having a front end; and
an actuator cooperable with the support member for pivotally tilting the front end of the front cushion relative to the frame members.

2. The vehicle seat assembly of claim 1 wherein the actuator is a tilt link motor hook up that causes movement of the support member to move the front end of the front cushion relative to the frame members.

3. The vehicle seat assembly of claim 1 wherein the front cushion is expanded polypropylene (EPP) foam.

4. The vehicle seat assembly of claim 1 wherein the front cushion includes a front surface and a set of notches that extend from the front surface, wherein each member of the set of notches is spaced apart from each other and wherein the support member extends through each member of the set of notches.

5. The vehicle seat assembly of claim 1 further including a frame cross member extending between the first and second side members, the front cushion pivoting on the support member and the frame cross member and sliding externally on the frame cross member during titling.

6. The vehicle seat assembly of claim 1 where the seat bottom includes a second seat cushion disposed over the front cushion and a trim cover disposed over the second seat cushion.

7. 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.

8. A vehicle seat assembly comprising:
a seat back pivotally disposed on a seat bottom, the seat bottom including:
a frame member having a rear end disposed proximate the seat back and a front end disposed opposite the rear end, the frame member having a frame cross member disposed adjacent to and rearward the front end of the frame member and;
a front cushion module including:
a support member having first and second ends disposed proximate the front end of the frame member, respectively;
a structural foam front cushion that receives and is supported by the support member, and the structural foam front cushion having a front end; and
an actuator cooperable with the support member for tilting the front end of the structural foam front cushion relative to the frame members, the front cushion pivoting on the support member and the frame cross member and sliding externally on the frame cross member during tilting.

9. The vehicle seat assembly of claim 8 wherein the actuator is a tilt link motor hook up that causes movement of the support member to move the front end of the structural foam front cushion relative to the frame members.

10. The vehicle seat assembly of claim 8 wherein the actuator causes movement of the support member to move the front end of the structural foam front cushion relative to the frame members.

11. The vehicle seat assembly of claim 8 wherein the structural foam front cushion is expanded polypropylene (EPP) foam.

12. The vehicle seat assembly of claim 8 wherein the structural foam front cushion includes a front surface and a set of notches that extend from the front surface, wherein each member of the set of notches is spaced apart from each other and wherein the support member extends through each member of the set of notches.

13. The vehicle seat assembly of claim 8 where the seat bottom includes a second seat cushion disposed over the front cushion and a trim cover disposed over the second seat cushion.

14. A vehicle seat assembly comprising:
a seat bottom including:
a frame member having a rear end and a front end disposed opposite the rear end; and
a front cushion module including:
a front cushion of structural foam pivotally disposed proximate the front end of the frame member, respectively; and
an actuator cooperable with the front cushion for tilting a front end and a rear end of the front cushion relative to the frame member.

15. The vehicle seat assembly of claim 14 wherein the actuator is a tilt link motor hook up that causes movement of the front end of the front cushion relative to the frame member.

16. The vehicle seat assembly of claim 14 wherein the front cushion is expanded polypropylene (EPP) foam.

17. The vehicle seat assembly of claim 14 wherein the front cushion module includes a support member associated with the frame member for supporting the front cushion and the front cushion includes a front surface and a set of notches that extend from the front surface, wherein each member of the set of notches is spaced apart from each other and wherein the support member extends through each member of the set of notches.

18. The vehicle seat assembly of claim 17 further including a frame cross member extending between first and second side members of the frame member, the front cushion pivoting on the support member and the frame cross member and sliding externally on the frame cross member during tilting.

19. The vehicle seat assembly of claim 18 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.

20. The vehicle seat assembly of claim 14 where the seat bottom includes a second seat cushion disposed over the front cushion and a trim cover disposed over the second seat cushion.
