Soft deployment air bag fold

摘要

An improved fold configuration of top mounted air bag cushions which tend to deploy high in a vehicle compartment and tend also to deploy at great velocity at an occupant's head uses several fold variations including a folded bubble on top, tucks, a pleat and rolls which inversely roll down the vehicle dashboard when an inflating fluid under pressure flows into the cushion, which folds can only unfold in sequence one after another so that the cushion does not unfold faster than it can be filled with inflating fluid and deploys relatively slowly in a downward trajectory.
