ABSTRACT:
A deployment door (24) for an inflatable air bag (18) has a door panel (80), a hinge (84), and first and second stress risers (128,192). The first stress riser (128) ruptures under stress induced in the door panel (80) upon movement of the air bag (18) forcefully against the door panel (80). The hinge (84) supports the door panel (80) for pivotal movement about an axis (190) when the first stress riser (128) has been ruptured. The hinge (84) includes a pivotal hinge leaf (150) having opposite side edges (180,182). One of the side edges (180) extends alongside the axis (190). The other side edge (182) is skewed relative to the axis (190). The second stress riser (192) ruptures under stress induced in the pivotal hinge leaf (150) when the door panel (80) pivots about the axis (190).
