Abstract
A vehicle seat having an inflatable airbag with the trim cover overlying the airbag being reinforced in the region adjacent to the airbag and having a weakened zone formed by cutting the reinforcement to create a tear line for deployment of the airbag through the trim cover. The reinforcement reduces stretching of the trim cover during deployment of the airbag at locations surrounding the tear line such that the trim cover ruptures along the tear line to produce a predictable airbag deployment.
