ABSTRACT:
A vehicular assembly incorporating knee bolsters and supporting the steering column. The assembly uses a beam fabricated largely from integrally injection molded plastic that is capable of reinforcing the knee bolsters, supporting the instrument panel and forming the ducts of an air distribution system. In the event of a collision, the knee bolster plates are stabilized so that they can cushion and limit the movement of the knees of a driver or passenger. The beam supports the steering column of the vehicle so that the first bending mode frequency of the combination of the steering wheel and the beam is greater than the first bending mode frequency of the body and is different from the idle excitation frequency of an engine employed in the vehicle.
