Abstract
An air bag chute assembly for an automotive instrument panel is injection molded to form an integral deployment chute, door, and attachment flange, The flange attaches to the instrument panel around an aperture in the instrument panel. The tubular chute extends interiorly from the flange to a lower end configured to receive an inflating air bag from an air bag module and defines a deployment path along a longitudinal axis. A door flap is disposed in an upper end of the chute rotatable from the flange to emerge through the aperture. The flap has an interior side impacted by the inflating air bag carrying a plurality of raised strengthening ribs. The flap has at least one closed-section hollow channel protruding from the interior side to a channel height extending beyond the strengthening ribs formed by gas-assist injection molding.
