Abstract
A seat-mounted side impact airbag module deployment door and a vehicle seat having such a deployment door are provided by a deployment door having a fabric outer panel, a fabric inner panel and an intermediate panel of rigid, resilient material, and in which the inner panel has spaced, parallel engagement elements held by retaining elements on the outer surface of sidewalls of a canister housing of an airbag module assembly placed in a seat recess and attached to an internal structural member of the seat. The fabric outer panel of the deployment door matches the adjacent fabric trim cover portion of the seat into which the deployment door is mounted.
Claims20
A motor vehicle seat comprising:
- an internal structural member;
- a recess in said seat adjacent the internal structural member, said recess leading to a deployment opening in a fabric trim cover portion of the seat;
- an airbag module assembly in said recess secured to the internal structural member, said airbag module assembly comprising a canister housing, an inflator and a folded deployable airbag cushion in fluid communication with said inflator for receiving inflation gases from said inflator, the canister housing having opposing first and second sidewalls defining a trough opening for deployment of the inflatable airbag cushion through the deployment opening in the fabric trim cover, first deployment door retaining means on said first sidewall and second deployment door retaining means on said second sidewall;
- and
- a deployment door positioned in said deployment opening in the fabric trim cover portion of the seat, said deployment door comprising a fabric outer trim panel, an inner panel, and an intermediate panel of, resilient material, the fabric of the outer trim panel being of the same fabric as the fabric of the trim cover portion of the seat, spaced first and second engagement means positioned on and extending generally transversely inwardly from said inner panel, said first and second engagement means secured respectively, by the first and second deployment door retaining means on the canister sidewalls, one of said first deployment door retaining means and said first engaging means being rupturable upon deployment of the airbag cushion to permit said deployment door to pivot around said second engagement means opening said deployment opening in the fabric trim cover portion of the seat.
A motor vehicle seat comprising:
- an internal structural member;
- a recess in said seat adjacent the internal structural member, said recess leading to a deployment opening in a fabric trim cover portion of the seat;
- an airbag module assembly in said recess secured to the internal structural member, said airbag module assembly comprising a canister housing, an inflator and a folded deployable airbag cushion in fluid communication with said inflator for receiving inflation gases from said inflator, the canister housing having opposing first and second sidewalls defining a trough opening for deployment of the inflatable airbag cushion through the deployment opening in the fabric trim cover, first deployment door retaining means on said first sidewall and second deployment door retaining means on said second sidewall;
- and
- a deployment door positioned in said deployment opening in the fabric trim cover portion of the seat, said deployment door comprising a fabric outer trim panel, an inner panel, and an intermediate panel of, resilient material, the fabric of the outer trim panel being of the same fabric as the fabric of the trim cover portion of the seat, spaced first and second engagement means positioned on and extending generally transversely inwardly from said inner panel, said first and second engagement means secured respectively, by the first and second deployment door retaining means on the canister sidewalls, one of said first deployment door retaining means and said first engaging means being rupturable upon deployment of the airbag cushion to permit said deployment door to pivot around said second engagement means opening said deployment opening in the fabric trim cover portion of the seat, and
- wherein said spaced first and second engagement means comprise parallel, spaced first and second fabric strips extending from the inner panel of the door, said first fabric strip being rupturably attached along a proximal edge thereof to the inner panel and the second fabric strip being non-rupturably attached along a proximal edge thereof to the inner panel.
A side-impact airbag cushion deployment door for positioning in a deployment opening in a fabric trim cover portion of a vehicle seat having an airbag module assembly in a recess in said seat and secured to an internal structural seat member, the airbag module assembly comprising a canister housing, an inflator, and a folded deployable airbag cushion in fluid communication with the inflator for receiving inflation gases from the inflator, the canister housing having opposing first and second sidewalls defining a trough opening for deployment of the inflatable airbag cushion through the deployment opening in the trim cover, said deployment door comprising:
- a fabric outer trim panel, an inner panel, and an intermediate panel of, resilient material, the fabric of the outer trim panel being of the same fabric as the fabric of the trim cover portion of the vehicle seat into which the deployment door is to be positioned;
- and
- spaced first and second engagement means positioned on and extending generally transversely inwardly from said inner panel, said first and second engagement means securable, respectively, to first and second deployment door retaining means on the first and second canister sidewalls.
A side-impact airbag cushion deployment door for positioning in a deployment opening in a fabric trim cover portion of a vehicle seat having an airbag module assembly in a recess in said seat and secured to an internal structural seat member, the airbag module assembly comprising a canister housing, an inflator, and a folded deployable airbag cushion in fluid communication with the inflator for receiving inflation gases from the inflator, the canister housing having opposing first and second sidewalls defining a trough opening for deployment of the inflatable airbag cushion through the deployment opening in the trim cover, said deployment door comprising:
- a fabric outer trim panel, an inner panel, and an intermediate panel of, resilient material, the fabric of the outer trim panel being of the same fabric as the fabric of the trim cover portion of the vehicle seat into which the deployment door is to be positioned;
- spaced first and second engagement means positioned on and extending generally transversely inwardly from said inner panel, said first and second engagement means securable, respectively, to first and second deployment door retaining means on the first and second canister sidewalls, and
- wherein said spaced first and second engagement means comprise parallel, spaced first and second fabric strips extending from the inner panel of the door, said first fabric strip being rupturably attached along a proximal edge thereof to the inner panel and the second fabric strip being non-rupturably attached along a proximal edge thereof to the inner panel.
