Abstract

Some embodiments are directed to an airbag lid defining a surface configured to cover a portion of an airbag prior to deployment. The airbag lid can be separated from a hinge side portion and a pillar side portion of an outer fringe by a seam that can tear and thereby separate the airbag lid from the hinge side portion and the pillar side portion of the outer fringe upon airbag deployment. The airbag lid includes a hinge portion disposed adjacent a hinge side edge of the airbag lid assembly, the hinge portion remaining attached to a window frame of a vehicle subsequent to airbag deployment. The hinge portion can include a hinge that is configured to enable the airbag lid to bend about the hinge, such that a portion of the airbag lid at an interior side of the hinge is maneuvered away from the structural pillar upon airbag deployment.
