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.
