Abstract: A cover for an airbag module of an air bag restraint system is formed by a single door which is mounted in front of the air bag module about horizontal pivots, the horizontal pivots are disposed on an axis positioned intermediate of the horizontal edges of the door, so that upon opening of the door a portion of the door will move to the air bag module side of the pivot axis thereby reducing the extent to which the door extends to the other side of the pivot axis when open, fastening means being provided to maintain the door in its closed position, until a predetermined load is applied thereto upon expansion of the air bag.

Abstract: An air bag restraint system includes an air bag module having an inflator with arming plunger which must be depressed to arm the inflator, the air bag module is mounted between a pair of side plates of a bracket assembly for pivotal movement between operative and inoperative positions, catch plates are provided for releasably securing the air bag module in its operative position, an arming mechanism having a pin mounted with respect to the arming plunger for transverse movement with respect thereto betweeen a disarmed and armed position, the pin being arranged to engage a contoured end face of the arming plunger to depress the arming plunger as it moves from its disarmed to its armed position, the pin being biased to its disarmed position and an anvil associated with the bracket assembly being provided for engagement of the pin to move it from its disarmed to its armed position as the air bag module is pivoted from its inoperative to its operative position.
