Active glove box door with ventilated reaction plate

摘要

An active glove box door includes a bladder member joined along an outer perimeter with a front wall by a hot weld seam to form an inflatable bladder. The bladder member includes a circumferential pleat for unfolding in response to an inflation gas during a crash event. A door inner liner is joined to a central region of the bladder member and forms a generally continuous plate behind the bladder member. The door inner liner interfaces with the instrument panel to provide a reaction surface for expansion of the bladder. The pleat has a peak disposed proximate to the door inner liner, wherein the peak includes a vent opening that delineates a collision region on the door inner liner. The door inner liner includes a plurality of perforations in the collision region permitting flow of inflation gas from the vent opening through the door inner liner.

主权项

1. An active glove box door for mounting in an opening of an instrument panel in an automotive vehicle, comprising:
a plastic-molded front wall for deploying outward from the opening; a plastic-molded bladder member joined along an outer perimeter with the front wall by a hot weld seam to form an inflatable bladder, wherein the bladder member includes at least one substantially circumferential pleat adjacent the weld seam for unfolding in response to an inflation gas injected into the inflatable bladder during a crash event; and a door inner liner joined to a central region of the bladder member and forming a generally continuous plate behind the bladder member, the door inner liner interfacing with the instrument panel to provide a reaction surface for expansion of the bladder member; wherein the pleat has a peak disposed proximate to the door inner liner, wherein the peak includes a vent opening that delineates a gas collision region on the door inner liner, wherein proximity of the collision region partially obstructs the vent opening, and wherein the door inner liner includes a plurality of perforations in the collision region permitting flow of inflation gas from the vent opening through the door inner liner.
