US Patent 9333934 Vehicle body structure

An airbag is fixed to a first location of a window in a stowed orientation and extends to a lower end of the window in a deployed orientation. A tether has an airbag end fixedly attached to the first location and an anchor end fixedly attached to a second location proximate the lower end of the window. The tether extends through a tether receiving aperture of the airbag such that during movement of the airbag from the stowed orientation to the deployed orientation the distal end moves along the tether. A one-way movement member is fixed to the tether proximate the anchor end. The one-way movement member passes through the tether receiving aperture in response to the airbag moving from to the deployed orientation and limits movement of the airbag back toward the stowed orientation.
