Abstract
A trim cover (14) fabricated of synthetic material that has a temperature-sensitive fragmentation characteristic fractures as a passenger restraint is deployed through a wall of the trim cover. A laminated backing (16) disposed on a back face of the trim cover wall contains fragments of the wall resulting from its fracturing by the deploying restraint. The laminated backing has a stretchable foam layer (18) having a front face adhered to the back of the wall and a non-tearable layer (20) that has a front face adhered in covering relation to a back face of the stretchable foam layer and that does not tear as a result of the fracturing of the wall by the deploying restraint.
