Abstract

A substrate is mounted to a vehicle seat frame, to provide a support surface for an occupant. The seat substrate is formed with a pair of guides to receive a pair of suspension wires of a vehicle seat suspension for translation of the pair of suspension wires within the pair of guides and to distribute an occupant load from the pair of suspension wires to the substrate. An air bladder is fastened to a plurality of retainers on the substrate. A first plurality of terminals is mounted to the substrate for electrical connection to a wire harness. A second plurality of terminals is mounted to the substrate, each in electrical communication with one of the first plurality of terminals, for electrical connection to a plurality of electrical devices in the vehicle seat assembly.

First claim

What is claimed is:

1. A vehicle seat assembly comprising:
a vehicle seat frame;
a seat substrate mounted to the vehicle seat frame, to provide a support surface for an occupant, the seat substrate being formed with a pair of guides, each sized to receive one of a pair of suspension wires of a vehicle seat suspension for translation of the pair of suspension wires within the pair of guides and to distribute an occupant load from the pair of suspension wires to the seat substrate; and
a vehicle seat suspension mounted to the vehicle seat frame, with a pair of suspension wires extending into the pair of guides;
wherein a plurality of receptacles is formed into the seat substrate; and
wherein the vehicle seat assembly further comprises a plurality of trim retention clips, each installed into one of the plurality of receptacles.

2. The vehicle seat assembly of claim 1 wherein the vehicle seat frame comprises a pair of side members and an upper cross member interconnecting the pair of side members; and
wherein the seat substrate is mounted to the pair of side members and the upper cross member.

3. The vehicle seat assembly of claim 2 wherein the vehicle seat frame further comprises an intermediate cross member connected to the pair of side members and spaced apart from the upper cross member; and
wherein the seat substrate is fastened to the intermediate cross member.

4. The vehicle seat assembly of claim 3 wherein the seat substrate is fastened to the intermediate cross member at a pair of locations, each aligned with one of the pair of guides.

5. The vehicle seat assembly of claim 3 further comprising a first pair of threaded fasteners insert-molded into the seat substrate; and
a second pair of threaded fasteners fastened to the intermediate cross member and the first pair of threaded fasteners.

6. A seat subassembly comprising:
a substrate adapted to be mounted to a frame of a vehicle seat assembly, to provide a support surface for an occupant;
a plurality of retainers provided on the substrate; and
an air bladder fastened to the plurality of retainers;
wherein the plurality of retainers each comprise a projection extending from the substrate with an opening formed through the substrate and partially surrounding the projection;
and wherein the air bladder further comprises a flexible support layer with a plurality of apertures formed therein, each sized to receive one of the plurality of projections on the substrate.

7. The seat subassembly of claim 6 wherein each of the apertures is sized smaller than a width of the corresponding projection.

8. The seat subassembly of claim 6 wherein a channel is formed into the substrate; and
wherein the seat subassembly further comprises at least one fluid tube in fluid communication with the air bladder and received within the channel.

9. A method of assembling a seat assembly comprising:
assembling a seat subassembly according to claim 6 by fastening the air bladder to the substrate; and
assembling the assembled seat subassembly to a frame of a vehicle seat assembly.

10. A vehicle seat assembly comprising:
a vehicle seat frame;
a seat subassembly, mounted to the vehicle seat frame, the seat subassembly comprising:
a substrate adapted to be mounted to a frame of a vehicle seat assembly,
a first plurality of terminals mounted to the substrate for electrical connection to a wire harness, and
a second plurality of terminals mounted to the substrate, each in electrical communication with one of the first plurality of terminals, for electrical connection to a plurality of electrical devices in the vehicle seat assembly;

a wire harness mounted to the vehicle seat frame, the wire harness comprising a plurality of wires, each electrically connected to one of the first plurality of terminals;
wherein the first plurality of terminals and the second plurality of terminals are mounted on the substrate on an inner surface that faces the vehicle seat frame; and
a cover fastened to the vehicle seat frame spaced apart from the substrate with the frame therebetween to enclose the second plurality of terminals within the vehicle seat assembly.

11. The vehicle seat assembly of claim 10 further comprising a plurality of wires each electrically connected to one of the first plurality of terminals and to one of the second plurality of terminals; and
wherein the substrate further comprises a plurality of retainers sized to retain the plurality of wires.

12. The vehicle seat assembly of claim 10 wherein the vehicle seat frame comprises a pair of side members and at least one upper cross member;
wherein the seat substrate is mounted to the vehicle seat frame proximate to the upper cross member; and
wherein the vehicle seat assembly further comprises:
an actuator supported by the vehicle seat frame with at least one terminal connected at least one of the plurality of second terminals, and
a head restraint operably connected to the actuator for adjustment by the actuator.

13. A method of assembling a seat assembly comprising:
assembling a seat subassembly comprising:
a substrate adapted to be mounted to a frame of a vehicle seat assembly,
a first plurality of terminals mounted to the substrate for electrical connection to a wire harness, and
a second plurality of terminals mounted to the substrate, each in electrical communication with one of the first plurality of terminals, for electrical connection to a plurality of electrical devices in the vehicle seat assembly, by installing the first plurality of terminals and the second plurality of terminals to the substrate;

assembling the assembled seat subassembly to a frame of a vehicle seat assembly;
installing a wire harness to the vehicle seat frame prior to assembling the assembled seat subassembly to the vehicle seat frame;
connecting the wire harness to the first plurality of terminals; and
fastening the substrate to the vehicle seat frame after the wire harness in connected to the first plurality of terminals.

14. A vehicle seat assembly comprising:
a vehicle seat frame;
a seat substrate mounted to the vehicle seat frame to provide a support surface for an occupant, the seat substrate being formed with a pair of guides, each sized to receive one of a pair of suspension wires of a vehicle seat suspension for translation of the pair of suspension wires within the pair of guides and to distribute an occupant load from the pair of suspension wires to the seat substrate;
a vehicle seat suspension mounted to the vehicle seat frame, with a pair of suspension wires extending into the pair of guides;
wherein the vehicle seat frame comprises a pair of side members and an upper cross member interconnecting the pair of side members;
wherein the seat substrate is mounted to the pair of side members and the upper cross member;
wherein the vehicle seat frame further comprises an intermediate cross member connected to the pair of side members and spaced apart from the upper cross member;
wherein the seat substrate is fastened to the intermediate cross member;
