Abstract

A vehicle seat suspension assembly includes a rear support for engagement with a torsion tube of a vehicle seat. First and second spring members have end portions engaged with the rear support. Intermediate cushion pan connectors are disposed on each of the first and second spring members. A cross support is coupled with the first and second spring members and includes power and data wiring apertures.

Claims

1. A vehicle seat suspension assembly comprising:

a rear support having a plurality of wire mounting apertures and configured for engagement with a torsion tube of a vehicle seat;

first and second spring members having end portions engaged with the rear support;

intermediate cushion pan connectors disposed on each of the first and second spring members; and

a cross support coupled with the first and second spring members and including power and data wire routing apertures.

2. The vehicle seat suspension assembly of claim 1, wherein each intermediate cushion pan connector includes an arcuate wedge adapted to interface with a complementary arcuate slot on a vehicle seat cushion pan.

3. The vehicle seat suspension assembly of claim 2, further comprising:

a polymeric overcoat disposed on the first and second spring members proximate the arcuate wedge of each intermediate cushion pan connector.

4. The vehicle seat suspension assembly of claim 1, further comprising:

trim attachment members disposed on the first and second spring members.

5. The vehicle seat suspension assembly of claim 1, wherein the rear support includes hooks adapted to engage the torsion tube.

6. A vehicle seat suspension assembly comprising:

a rear support including hooks with load distribution tabs that engage a torsion tube of a vehicle seat;

first and second spring members having a front portion with a cushion pan interface and a rear portion forming part of the hooks; and

a cross support including first and second sets of wire routing apertures and a climate control air supply duct disposed between the first and second sets of wire routing apertures.

7. The vehicle seat suspension assembly of claim 6, wherein the rear support includes a plurality of wire routing apertures.

8. The vehicle seat suspension assembly of claim 6, further comprising:

intermediate cushion pan connectors that are configured to interface with receiving slots on a vehicle seat cushion pan.

9. The vehicle seat suspension assembly of claim 8, wherein the intermediate cushion pan connectors include an arcuate wedge configured to interface with a complementary arcuate slot on the vehicle seat cushion pan.

10. The vehicle seat suspension assembly of claim 6, further comprising:

trim attachment members disposed on the first and second spring members.

11. The vehicle seat suspension assembly of claim 6, wherein the first and second sets of wire routing apertures include indicia disposed adjacent to the apertures on the rear support, the indicia being adapted to relay connectivity information to an installer.

12. A vehicle seat suspension assembly comprising:

a rear support including hooks with load distribution tabs that engage a torsion tube of a vehicle seat and further including wire routing apertures; and

first and second spring members having a front portion with a wedge configured to be removably coupled with a complementary suspension assembly retainer on a vehicle seat cushion pan, and a rear portion forming part of the hooks.

13. The vehicle seat suspension assembly of claim 12, wherein the rear support includes a first substantially horizontal portion, and a second portion that is integrally formed with the hooks, the second portion extending orthogonally from the first substantially horizontal portion.

14. The vehicle seat suspension assembly of claim 12, further comprising:

a polymeric overcoat disposed on the first and second spring members proximate the wedge.

15. The vehicle seat suspension assembly of claim 12, further comprising:

trim attachment members disposed on the first and second spring members.

16. The vehicle seat suspension assembly of claim 12, wherein the wedge includes an arcuate construction and wherein the suspension assembly retainer includes an arcuate slot for receiving the wedge.

17. The vehicle seat suspension assembly of claim 12, wherein the wire routing apertures include indicia disposed adjacent to the apertures on the rear support, the indicia being adapted to relay connectivity information to an installer.

18. The vehicle seat suspension assembly of claim 12, further comprising:

a forward cross support having a climate control air supply duct disposed at a center portion thereof.

19. The vehicle seat suspension assembly of claim 18, wherein the forward cross support includes forward and rearward ribs and a plurality of wire routing apertures disposed therebetween.
