Abstract
A vehicle seat having an inflatable airbag therein which deploys through a tear line such as a seam in the seat trim cover. A force concentrator is provided to ensure deployment of the airbag through the intended location rather than rupturing the trim cover elsewhere. The force concentrator includes two panels of a flexible and substantially non-stretchable material having a strength sufficient to withstand the force of the inflating airbag without tearing. The panels are attached to the trim cover at the tear line and extend away from the tear line in opposite directions. Distal ends of the panels are joined to one another forming a sleeve that circumscribes the airbag.
