Abstract
A deployment structure (28) for use with an inflatable vehicle occupant restraint (12) is rupturable by the restraint (12) when the restraint (12) is being inflated. The deployment structure (28) includes a plastic part (52). The plastic part (52) has a seam (158) along which it is rupturable under stress induced by movement of the restraint (12) forcefully against the deployment structure (28). The plastic part (52) includes first and second bodies (150,152) of plastic foam which are joined to each other at the seam (158). The first and second bodies (150,152) of plastic foam preferably have respective values of durometer hardness that differ from each other.
