Abstract
Enhanced airbag covers are disclosed. Each of the covers permits deployment of a compacted airbag cushion along multiple axes, thereby decreasing the momentum of the vehicle occupant relative to the airbag, and enhancing the ability of the cushion to protect vehicle occupants who are out of their nominal positions. Covers may include a plurality of frontal portions separated by a frontal seam or seams that tear open to permit emergence of the cushion between the frontal portions. In some implementations, each cover has a peripheral skirt and/or a junction between the frontal portions and peripheral skirt that opens to permit emergence of the folded cushion along additional axes. The peripheral skirt and/or junction may open consistently, regardless of whether the frontal portions have separated.
