Abstract

A seat system having a seat bottom and a cross beam. The seat bottom may include a support block, a cushion, and a trim cover. The cushion may be disposed on the support block. The trim cover may be disposed on the cushion. The cross beam that is disposed on the support block such that the cross beam does not extend through the seat bottom.

First claim

What is claimed is:

1. A seat system comprising:
a seat bottom that includes a support block, a cushion disposed on the support block, and a trim cover disposed on the cushion; and
a cross beam that extends laterally across the seat bottom and is disposed on a top side of the support block such that the cross beam does not extend through the seat bottom, wherein the support block includes a front side, a rear flange that extends away from the front side and the cushion, a bottom side, and a top flange that extends from the rear flange in a direction that extends away from the bottom side, the cushion extends over the top flange to the rear flange, the cross beam is disposed on the rear flange, and the trim cover extends over the top flange to the rear flange such that the trim cover is disposed between the cross beam and the top flange.

2. The seat system of claim 1 wherein the cross beam inhibits movement of the seat bottom in response to a vehicle impact event.

3. The seat system of claim 1 wherein the cross beam does not engage the cushion and the trim cover.

4. The seat system of claim 1 wherein the cross beam is completely disposed in a rearward direction from the cushion and the trim cover.

5. The seat system of claim 1 wherein the cross beam is mounted to a vehicle body structure.

6. The seat system of claim 5 wherein the cross beam is stationary and is spaced apart from the seat back, the cushion, and the trim cover.

7. The seat system of claim 6 wherein the cross beam is disposed between the seat bottom and the seat back and is not part of the seat back.

8. The seat system of claim 1 wherein the cross beam is spaced apart from the trim cover.

9. The seat system of claim 1 wherein the cross beam is spaced apart from the cushion.

10. A seat system comprising:
a seat bottom that includes a support block, a cushion disposed on the support block, and a trim cover disposed on the cushion; and
a cross beam that extends laterally across the seat bottom and is disposed on a top side of the support block such that the cross beam does not extend through the seat bottom, wherein the support block includes a front side, a rear flange that extends away from the front side and the cushion, a bottom side, and a top flange that extends from the rear flange in a direction that extends away from the bottom side, the cushion extends over the top flange to the rear flange, the cross beam is disposed on the rear flange, and the rear flange has a groove that is disposed adjacent to the top flange, wherein the cushion and the trim cover extend into the groove.

11. The seat system of claim 10 wherein the trim cover is spaced apart from the cross beam.

12. The seat system of claim 10 wherein the rear flange has first and second protrusions that extend away from the bottom side and engage the cross beam, wherein the groove is disposed between the first and second protrusions and the top flange.

13. The seat system of claim 10 wherein the cushion is spaced apart from the cross beam.

14. A seat system comprising:
a seat bottom that includes:
a support block having a front side, a first rear flange, and a second rear flange, wherein the first rear flange and the second rear flange are spaced apart from each other, protrude rearwardly on a rear end of the support block, and each have a first protrusion that protrudes upwardly toward a seat back,
a cushion that is disposed on the support block and extends across the front side, and
a trim cover that is disposed on the cushion; and

a cross beam that extends lengthwise laterally across the seat bottom such that the cross beam does not extend through the seat bottom, wherein the cross beam is disposed on the first protrusion of the first rear flange and the first protrusion of the second rear flange and does not engage the cushion and does not engage the trim cover.

15. The seat system of claim 14 wherein the support block includes a third rear flange, wherein a first gap separates the first rear flange from the second rear flange and a second gap separates the second rear flange from the third rear flange, and the cross beam does not engage the third rear flange.

16. The seat system of claim 15 wherein the cross beam includes a first and second cross beam mounting brackets for mounting the cross beam to a vehicle body structure, wherein the first and second cross beam mounting brackets are received in the first and second gaps, respectively, and are spaced apart from the cushion.

17. The seat system of claim 15 wherein a seat back is disposed above the cross beam, the first rear flange, the second rear flange, and the third rear flange such that the seat back is spaced apart from and does not engage the first rear flange, the second rear flange, and the third rear flange.

18. The seat system of claim 15 wherein the first rear flange includes a second protrusion that is spaced apart from the first protrusion, wherein the cross beam engages the first protrusion and the second protrusion.

19. The seat system of claim 18 wherein the second rear flange includes a second protrusion that is spaced apart from the first protrusion of the second rear flange, wherein the cross beam engages the first protrusion and the second protrusion of the second rear flange.

20. The seat system of claim 14 wherein the support block has a mounting hook for securing the seat bottom to a vehicle body structure, wherein the cross beam inhibits the seat bottom from rotating about the mounting hook.
