Laminated backing for containing fragments of a fractured trim cover during deployment of a passenger restraint
First Claim
Patent Images
1. A vehicle comprising:
- a deployable passenger restraint system comprising a passenger restraint that is deployed through a wall of a trim part fabricated of synthetic material that has a temperature-sensitive fragmentation characteristic, wherein deployment of the restraint creates an opening in the trim part wall by fracturing the trim part wall, with the trim part wall having a line of weakness that defines, in the trim part, a door that is swung open about a hinge line by the deploying restraint to create an opening through which the restraint deploys; and
a laminated backing disposed on a back face of the trim part wall for containment of fragments of the wall resulting from its fracturing by the deploying restraint;
wherein the laminated backing comprises a stretchable foam layer having a front face adhered to the back of the wall and a non-tearable layer 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.

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.
