Abstract

Airbag cushions are provided that mitigate the potential for injury to an occupant's neck via a sloped face, a particular cushion height, and/or a relatively flat top portion. These airbag cushions can be used with seat belt systems that moderates the seat belt loads acting on the occupant to allow an improved synchronization of the occupant torso and head rebound timing, which in turn limits head and torso differential loading (frontal whiplash) and therefore occupant neck loads and neck, based on the position of the occupant, loads on the seatbelt, or a predetermined time in the crash event.
