초록 ▼

A self piercing cover assembly for concealing an air bag restraint system in a vehicle passenger compartment has a plurality of retractable cutter blades that are attached to the underside of an invisible door beneath the instrument panel by leaf springs. When the air bag inflates, it pushes the cutter blades out against the bias of springs to cut through the instrument panel at several locations along the front edge of the door making it easier for the door to swing open. The cutter blades retract under the action of the leaf springs so that the cutting edges are below the surface of the cover assembly to protect against contact with the cutting edges after the air bag collapses.

대표청구항 ▼

A self piercing cover assembly for concealing an air bag in a vehicle passenger compartment comprising: a support that is adapted for securement beneath a decorative panel in a vehicle passenger compartment; a door that closes a rectangular opening in the support for deployment of an air bag; the door having a rear end that is connected to the support by a hinge and a front end that is spaced from an edge of the support to maintain a slot at the front end of the door when the door is closed; the outer surface of the support and the hinged door being bonded to an elastomeric cushion formed in an underlying relationship to a polymeric skin that forms an outer surface of a decorative panel; the support having a depending bracket for holding an air bag housing beneath the opening in alignment with the door and that provides a space beneath the door; piercing means comprising: a plurality of piercing members disposed in the space beneath the door and attached to an underside of the door; the piercing members having springs holding the piercing members in a retracted position and cutter blades that are aligned with the slot to cut through the cushion and skin of the decorative panel; the piercing members being moveable outwardly by initial inflation of an air bag so that the cutter blades project through the slot and cut through the cushion and skin at several locations and form a tear line at the front end of the door that is easily ruptured by door itself as it is pivoted outwardly by force of an inflating air bag; the piercing members being retractable by the springs so that sharp cutting edges of the cutter blades are below the surface of the skin that is attached to the door as an air bag collapses and the springs overcome the force of the collapsing air bag to protect against contact with the sharp cutting edges of the cutter blades, the front end of the door having a flange that is spaced from a flange of the support to define the slot that is maintained when the door is closed and reduces the thickness of the cushion to be cut by the cutter blades, and the cutter blades having tips that are disposed between the flanges.
