Abstract
A knee bolster system for absorbing an impact energy of an occupant's knee is provided with a multi-level force load limiter. The multi-level force load limiter includes three force load limiters. A first force load limiter includes a contact plate for receiving an impact force by the occupant's knee during a vehicle collision. A second force load limiter includes a torsional deflection rod for deforming torsionally by allowing relative rotation, and a third force load limiter includes a locking gear and a female locking base for locking further rotation of a rotational arm after rotation of the torsional deflection rod in the second force load limiter by a predetermined angle based on rotation of the rotational arm. Accordingly, the multi-level force load limiter can create a higher torsion force on the rotational arm of the knee bolster system.
