Abstract

A seat attachment assembly for attaching components to a seat cushion is provided. A central base has at least one footing with an opening adapted for being encapsulated in the cushion. A cylindrical shaft extends generally perpendicular from the central base and defines a cylindrical opening therein. A retention clip has an extension portion sized to be received and retained in the cylindrical opening by an interference fit.

Claims

1. A seat cushion assembly comprising:

a seat cushion;

an attachment port molded in the seat cushion, the attachment port including;

at least one footing having an opening so that the seat cushion encapsulates the footing and seat cushion material extends through the opening; and

a cylindrical shaft extending generally perpendicular from the footing and defining a cylindrical opening therein, wherein the cylindrical shaft extends a distance so a distal end is at least coplanar with an exterior surface of the seat cushion,

wherein the seat cushion material contacts an outer circumference along at least a portion of a length of the cylindrical shaft.

2. The seats cushion assembly of claim 1 wherein at least a second portion of the length of the cylindrical shaft extends beyond an exterior surface of the seat cushion.

3. The seat cushion assembly of claim 1 wherein the at least one footing includes a plurality of webbed fingers that defines a plurality of webbed openings, the search cushion material extending through the plurality webbed openings to provide retention in the seat cushion.

4. The seat cushion assembly of claim 1 wherein the attachment port further comprises first and second footings disposed in the seat cushion and extending in a direction generally perpendicular from the cylindrical shaft.

5. The seat cushion assembly of claim 1 further comprising a retention clip having an extension portion sized to be received and retained in the cylindrical opening by an interference fit.

6. A seat assembly comprising:

a seat back having a seat cushion;

an attachment port molded in the seat cushion, the attachment port including;

a central base encapsulated in the seat cushion for retaining the attachment port to the cushion;

at least one footing extending from the central base and having an opening so that the seat cushion encapsulates the footing and seat cushion material extends through the opening;

a cylindrical shaft extending generally perpendicular from the footing and defining a cylindrical opening therein, wherein the cylindrical shaft extends a distance so a distal end is at least coplanar with an exterior surface of the seat cushion, wherein the seat cushion material contacts an outer circumference along at least a portion of a length of the cylindrical shaft; and

a retention clip having an extension portion sized to be received and retained in the cylindrical opening by an interference fit to secure a component to the seat back.

7. The seat assembly of claim 6 wherein at least a second portion of the length of the cylindrical shaft extends beyond an exterior surface of the seat cushion.

8. The seat assembly of claim 6 wherein the attachment port includes a detent extending radially inward along a circumference of the cylindrical opening.

9. The seat assembly of claim 8 wherein the retention clip includes at least one tooth that extends radially from the extension portion, the at least one tooth engages the detent such that the interference fit comprises a snap-fit.

10. The seat assembly of claim 6 wherein the retention clip includes a connection portion for securing the retention clip to the component.

11. The seat assembly of claim 10 wherein the connection portion includes an arc-shaped profile for being coupled to a bar.

12. The seat assembly of claim 10 wherein the connection portion is coupled to a wiring harness.

13. The seat assembly of claim 6 wherein the attachment port further comprises first and second footings disposed in the seat cushion and extending from the central base in a direction generally perpendicular from the cylindrical shaft.

14. The seat assembly of claim 6 wherein first and second footings that are spaced apart from each other and have an arcuate arm with a web defined within the arcuate arm.

15. The seat assembly of claim 6 wherein the attachment port extends from a rear surface of the seat back.

16. A seat attachment assembly for attaching components to a seat cushion, the assembly comprising:

a central base having at least one footing with an opening adapted for being encapsulated in the seat cushion;

a cylindrical shaft extending generally perpendicular from the central base and defining a cylindrical opening therein, wherein the cylindrical shaft extends a distance so a distal end is at least coplanar with an exterior surface of the seat cushion; and

a retention clip having an extension portion sized to be received and retained in the cylindrical opening by an interference fit.

17. The seat attachment assembly of claim 16 wherein the cylindrical shaft includes a detent extending radially inward along a circumference of the cylindrical opening.

18. The seat assembly of claim 17 wherein the retention clip includes at least one tooth that extends radially from the extension portion, the at least one tooth engages the detent such that the interference fit comprises a snap-fit.

19. The seat attachment assembly of claim 16 wherein the at least one footing includes a plurality of webbed fingers that defines a webbed openings, the search cushion material extending through the plurality webbed openings to provide retention in the seat cushion.

20. The seat assembly of claim 16 wherein at least a second portion of the length of the cylindrical shaft extends beyond an exterior surface of the seat cushion.
