<p>A one-piece moulded plastic closure element (12) for an inflatable air bag restraint system (10) including a face portion (14) in which two air bag release doors (50, 52) are defined by tear lines (54). Confronting arms (26A, 26C) for locking the element (12) to an air bag housing (32) are located adjacent door hinge sections (62, 64) which are integrally formed with reinforcement ribs (66) which act to restrain outward movement of the doors (50, 52) and prevent undesired closure tearing upon inflation of the air bag (42). In addition to or instead of the ribs (66) the hinge sections (62, 64) may include integral thickened portions for the same purposes. <IMAGE></p> |
