Abstract

A unique glove box and restraint system including a reaction bracket is provided. The glove box assembly includes a reaction bracket that is attached to a hinge mechanism. The reaction bracket carries a storage bin, a latch, a trim plate, a tether, and a gas source. The gas source is held in an operative relationship with an inflatable air bag. The inflatable air bag is coupled to the trim plate. The trim plate includes an outer panel and an inner attachment plate. The inner attachment plate is selectively coupled to the reaction bracket by a mechanism that disengages when it experiences an outward force greater than a predetermined amount. The latch is connected to the reaction bracket at the end opposing the hinge. During conditions of rapid deceleration, the gas source produces gas to inflate the air bag if electrical current is sent to trigger the gas source by the vehicle crash sensing system. As the air bag fills force is exerted on the trim plate, thereby disengaging the trim plate from the reaction bracket and projecting it outward. The air bag pushes off the reaction bracket to project itself outward being directed by the orientation of the gas source and by at least one tether. Upon deployment of the air bag, the storage bin portion of the glove box remains in place while the air bag and trim panel act to improve occupant safety.
