Abstract
A deployment flap for a vehicular airbag system is disclosed. The deployment flap includes: a main body portion; wings that extend laterally from the main body portion; and at least one expandable portion. The main body portion includes a tear seam that is configured to separate during the inflation of an airbag such that the airbag extends through the deployment flap. The at least one expandable portion is reconfigurable from a collapsed configuration into an expanded configuration to thereby facilitate lengthening of the main body portion and the wings prior to separation of the tear seam during multi-stage inflation of the airbag, whereby the deployment flap directs the airbag and inhibits eccentric deployment.
