Abstract
A steering column system of a vehicle includes: a rotatable, hollow steering shaft that has a proximal end attached to a steering wheel and is configured to transfer rotational input at the steering wheel to a steering rack of the vehicle; a stationary driver-side airbag (DAB) shaft that is surrounded by the steering shaft and extends along the steering shaft; and a DAB module that contains an airbag and is fixedly mounted to a proximal end of the DAB shaft within a region of the steering wheel. The airbag contained in the DAB module is formed to have a substantially circular center chamber and a pair of side extension chambers, one of the side extension chambers disposed on a right side of the center chamber, and the other of the side extension chambers disposed on a left side of the center chamber.
