Abstract

A seat cover for use with vehicle seats with or without side deployed airbags. In an example, the seat cover is made of a uni-body construction with upper and lower sections for respectively covering a seat back and seat cushion. Openings are provided in the upper and lower sections for insertion of the seat back and seat cushion. A side panel is disposed on each lateral side of the upper section that aligns with an expected path of the airbag when deployed. A frangible seam couples the panel to the remaining portion of the seat cover. The frangible seam fails at a force sufficiently less than the force of a deploying airbag. Thus when the airbag is deployed the force consumed by cleaving the frangible seam panel does not impede airbag deployment. Also included is an alignment member to position the panel in the expected path of the deploying airbag.

Claims

1. A seat cover for use with a vehicle seat having a side deployed airbag, the seat cover comprising:

an upper section comprising a flexible woven fabric material that forms an enclosure and an opening provided in the material;

an alignment element attached to the upper section adjacent the opening and including a resilient member set in the alignment element;

an elongate side panel coupled to a lateral side of the upper section along an interface; and

a frangible seam along a portion of the interface that fails at a force below a force that impedes airbag deployment, the frangible seam including a top stitching of a nylon thread, an underside stitching of a polyester thread, and a stitch length of about 5 mm, the top stitching having a strength greater than the strength of the underside stitching, a ratio of the strength of the top stitching to the strength of the underside stitching being about 7, so that when the side panel is aligned with an expected path of a deploying airbag, and the airbag is deployed, the force of the deploying airbag separates the panel from the upper section along the seam to form a gap and the airbag fully deploys through the gap, wherein the flexible woven fabric material comprises a weave of weft yarn and warp yarn so that the flexible woven fabric material is capable of flexing in any direction.

2. The seat cover of claim 1, further comprising a lower section joined to the upper section and comprising a flexible woven fabric material that forms an enclosure and having an opening.

3. The seat cover of claim 1, wherein at least one of the threads of the seam comprises an elongated element stitched through the panel and the upper section.

4. The seat cover of claim 1, wherein the panel extends from adjacent a portion of the opening and along the lateral side of the upper section to substantially adjacent a distal portion of the opening.

5. The seat cover of claim 4, wherein the seam extends along the length of a forward looking edge of the panel.

6. The seat cover of claim 1, wherein the airbag deploys through a seam provided in the vehicle seat, and wherein the upper section comprises a front side and the frangible seam in the upper section is disposed in a region between the seam provided in the vehicle seat and the front side.

7. A seat cover for use with a vehicle seat that is equipped with a side deployed airbag, the seat cover comprising:

an upper section that forms an enclosure with an opening for receiving therein a seat back having the side deployed airbag;

a lower section connected to the upper section and that is formed into an enclosure with an opening for receiving therein a seat cushion attached to the seat back to define a space between the seat back and seat cushion, wherein the upper section and the lower section each comprise a flexible woven fabric material;

an alignment element attached to at least one of the upper section and the lower section adjacent the corresponding opening and including a resilient member set in the alignment element; and

a frangible seam along a portion of a lateral side of the upper section that fails at a force below a force that impedes airbag deployment, the frangible seam including a top stitching of a nylon thread, an underside stitching of a polyester thread, and a stitch length of about 5 mm, the top stitching having a strength greater than the strength of the underside stitching, a ratio of the strength of the top stitching to the strength of the underside stitching being about 7, so that when the frangible seam is aligned with an expected path of a deploying airbag, and the airbag is deployed, the force of the deploying airbag cleaves the seam to form a gap in the upper section so that the airbag fully deploys through the gap, wherein the flexible woven fabric material comprises a weave of weft yarn and warp yarn so that the flexible woven fabric material is capable of flexing in any direction.

8. The seat cover of claim 7, further comprising an elongated side panel coupled to the lateral side of the upper section along an interface, wherein at least one of the threads of the seam comprises an elongated element single stitched through the panel and the upper section along a portion of the interface.

9. The seat cover of claim 7, wherein the alignment element includes a plurality of eyelets and the seat cover further includes a strap coupled to the lower section and including a hook, the hook being configured to releasably couple the strap to one of the eyelets to removably secure the seat cover to the vehicle seat.

10. A vehicle seat comprising:

a seat back having a front, back, and lateral sides;

an airbag provided in the seat back and oriented to have a projected airbag deployment path that exits the seat back through at least one of the lateral sides;

a seat cushion coupled with the seat back along a portion of the periphery of the seat cushion to define a space between the seat cushion and seat back;

a seat cover comprising;

an upper section enclosing a substantial portion of the seat back, the upper section comprising a flexible woven fabric material that forms an enclosure and an opening provided in the flexible woven fabric material for receiving the seat back;

a lower section enclosing a substantial portion of the seat cushion, the lower section comprising a flexible woven fabric material that forms an enclosure and an opening provided in the flexible woven fabric material for receiving the seat cushion, wherein the flexible woven fabric material of the upper section and the lower section comprises a weave of weft yarn and warp yarn so that the flexible woven fabric material is capable of flexing in any direction;

an alignment element attached to at least one of the upper section and the lower section adjacent the corresponding opening and including a resilient member set in the alignment element;

a side panel coupled to at least one of the lateral sides of the upper section along an interface; and

a frangible seam along a portion of the interface that fails at a force below a force that impedes airbag deployment, the frangible seam including a top stitching of a nylon thread, an underside stitching of a polyester thread, and a stitch length of about 5 mm, the top stitching having a strength greater than the strength of the underside stitching, a ratio of the strength of the top stitching to the strength of the underside stitching being about 7, so that when the side panel is aligned with the projected airbag deployment path, and the airbag is deployed, the force of the deploying airbag separates the panel from the upper section along the seam to form a gap and the airbag fully deploys through the gap.

11. The seat cover of claim 10, wherein at least one of the threads of the seam comprises an elongated element single stitched through the panel and upper section.

12. The seat cover of claim 10, further comprising eyelets in the alignment element selectively engageable with hooks attached to straps that depend from the lower section.

13. The seat cover of claim 10, wherein the airbag deploys through a seam provided in the vehicle seat, and wherein the upper section comprises a front side and the frangible seam in the upper section is disposed in a region between the seam provided in the vehicle seat and the front side.
