Abstract
An inflatable rigid knee airbag system for assisting in positioning and decelerating a vehicle occupant is disclosed. The system includes an inflatable knee airbag having a front panel, an annular, accordion-folded bellows panel, and a rear panel having an inflation orifice and mounting brackets; and a pyrotechnic inflator. The system helps to improve the kinematics of a vehicle occupant in relation to a primary airbag cushion by bolstering the knees of the occupant. The system of the invention may be mounted in a vehicle in a panel under the steering column, in the door of a glove box, or in the lower section of the instrument panel of the vehicle directly in front of the occupant's lower legs.
