<p>A module housing (14) of a vehicle occupant restraint module assembly (10, 12) encloses a stowed airbag (22) and its inflator (20). A snap-on cover (16) of molded plastics material such as a polyolefin engages a rim (40) of the housing and has a flat face portion (44) with weakened tear lines (58, 60) to form doors (A, B) as the airbag inflates. The cover is secured against radial stresses by a heat-shrunk band (24), for example nylon 66 or rayon, applied around its peripheral surface (26). <IMAGE></p> |
