REINFORCED TRIM COVER FOR A VEHICLE SEAT ASSEMBLY WITH A TEAR LINE FOR AIRBAG DEPLOYMENT

摘要

A vehicle seat (10) having an inflatable airbag module (58) with the trim cover (24) overlying the airbag being reinforced in the region adjacent to the airbag (70) and having a weakened zone formed by cutting the reinforcement (52) to create a tear line (32) for deployment of the airbag (70) through the trim cover (80). The reinforcement reduces stretching of the trim cover piece (30) during deployment of the airbag (70) at locations surrounding the tear line (32) such that the trim cover (30) ruptures along the tear line (32) to produce a predictable airbag deployment.
