Abstract
An inflatable rigid knee airbag system for assisting in positioning and decelerating a vehicle occupant is disclosed. The system may include a front and a rear rigid panel, which may be made from sheet metal. The front and rear rigid panels define at least a portion of an inflatable chamber. The inflatable chamber is in fluid communication with an inflator that injects inflatable gas into the inflatable chamber when accident conditions exist. A support core positioned between the front and rear panels dampens vibrations of the front and rear panels and minimizes unsightly denting of the front panel when the inflatable rigid knee airbag system is in a pre-deployment state. The support core may be made from foam.
