Abstract

A vehicle seat assembly is provided with a structural member adapted to be mounted within a vehicle to provide support to an occupant. The structural member has at least one channel formed therein. A cushion member is provided adjacent to the structural layer. The cushion member has at least one channel formed therethrough. A trim member is secured over the cushion member to form a seating surface. At least one attachment member is mounted to the trim member extending through the at least one channel of the cushion member. The at least one attachment member extends into the at least one channel of the structural member such that at least one of the trim material and the cushion layer is retained on the structural member.

Claims

1. A vehicle seat assembly comprising:

a structural layer formed of a first foam material and adapted to be mounted to a seat frame to provide support to an occupant, the structural layer having at least one channel formed therein;

a cushion layer formed of a second foam material provided adjacent to the structural layer, the cushion layer having at least one channel formed therethrough;

a trim member secured over the cushion layer to form a seating surface; and

at least one attachment member mounted to the trim member along at least one securement portion, the attachment member extending through the at least one channel of the cushion layer and extending into the at least one channel of the structural layer such that the attachment member is engaged with and thereby retained by at least the structural layer,

wherein the at least one attachment member includes a first engagement feature having at least one saw tooth protrusion that is engaged with and thereby retained in the channel of the structural layer and a second engagement feature located between the securement portion and the first engagement feature that is sized to be received within the channel of the cushion layer,

the trim member and the cushion layer thereby secured on the structural layer by the attachment member.

2. The vehicle seat assembly of claim 1 wherein the first engagement feature of the attachment member further comprises a plurality of saw tooth protrusions engaged with and thereby retained by the at least one channel of the structural layer.

3. The vehicle seat assembly of claim 2 wherein the second engagement feature of attachment member further comprises a block member that is sized to be received within the at least one channel of the cushion layer.

4. The vehicle seat assembly of claim 1 wherein the attachment member is sewn to the trim member.

5. A vehicle seat assembly comprising:

a structural layer formed of a first foam material and adapted to be mounted to a seat frame to provide support to an occupant, the structural layer having a first channel and a second channel formed therein at spaced apart locations;

a cushion layer formed of a second foam material provided adjacent to the structural layer, the cushion layer having a first channel and a second channel formed therethrough and corresponding respectively with the first channel and the second channel of the structural layer;

a trim member secured over the cushion layer to form a seating surface;

a first attachment member mounted to the trim member along at least one securement tab, the attachment member extending through the first channel of the cushion layer and extending into the first channel of the structural layer such that the first attachment member is engaged with and thereby retained by at least the structural layer, the trim member and the cushion layer thereby secured on the structural layer by the first attachment member; and

a second attachment member mounted to the trim member along at least one securement tab, the attachment member extends extending through the second channel of the cushion layer and extending into the second channel of the structural layer such that the first attachment member is engaged with and thereby retained by at least the structural layer, the trim member and the cushion layer thereby secured on the structural layer by the second attachment layer,

wherein at least one of the first attachment member and the second attachment member includes a first engagement feature having at least one saw tooth protrusion that is engaged with and thereby retained in the channel of the structural layer and a second engagement feature located between the securement tab and the first engagement feature that is sized to be received within the channel of the cushion layer.

6. The vehicle seat assembly of claim 5 wherein the first engagement feature further comprises a plurality of saw tooth protrusions engaged with and thereby retained by the at least one of the first channel and the second channel of the cushion layer.

7. The vehicle seat assembly of claim 6 wherein the second engagement feature further comprises a block member that is sized to be received within the at least one channel of the cushion layer.

8. A vehicle seat assembly comprising:

a cushion composite comprising;

a structural layer formed of a first foam material and adapted to be mounted to a seat frame to provide support to an occupant;

a cushion layer formed of a second foam material provided adjacent to the structural layer; and

a channel extending through the structural layer and at least partially into the cushion layer;

a trim material secured over the cushion composite to form a seating surface; and

at least one attachment member mounted to the trim material along at least one securement portion, the attachment member adapted to be inserted into the channel and extend through the cushion layer and extending into the a channel along the structural layer such that the attachment member is engaged with and thereby retained by at least the structural layer, wherein the at least one attachment member includes a first engagement feature having at least one saw tooth protrusion that is engaged with and thereby retained in the channel of the structural layer and a second engagement feature located between the securement portion and the first engagement feature that is sized to be received within the channel of the cushion layer,

wherein the trim material and the cushion layer thereby secured on the structural layer by the attachment member.

9. The vehicle seat assembly of claim 8 wherein the first engagement feature of the attachment member further comprises a plurality of saw tooth protrusions engaged with and thereby retained by the at least one channel of the structural layer.

10. The vehicle seat assembly of claim 9 wherein the second engagement feature of the attachment member further comprises a block member that is sized to be received within the at least one channel of the cushion layer.
