Embodiment Construction

[0028] Referring to the drawings, wherein like numerals refer to like parts throughout the several views, an assembly 20 for controlling the kinematics of an occupant of a vehicle 22 includes a front console 24 having a panel 26 . Assembly 20 includes torsion bar 28 fixed relative to front console 24 . Assembly 20 includes gear 30 secured to torsion bar 28 . Assembly 20 includes rack 32 . Rack 32 includes teeth 34 that mesh with gear 30 . The rack 32 extends toward the face plate 26 .

[0029] The force F applied to panel 26 such as when an object strikes panel 26 during a vehicle collision (at image 3 with Figure 4 shown in ) will be transmitted to the rack 32. Rack 32 is urged by force F to move relative to torsion bar 28 . The force F pushing the rack 32 is transmitted to the torsion bar 28 via the engagement of the rack 32 with the gear 30 , thereby applying a torque T to the torsion bar 28 . Torque T causes torsion bar 28 to twist. The twisting of the torsion ba...

Abstract

The invention provides an energy-absorbing knee bolster. An assembly includes a front console having a panel. The assembly includes a torsion bar fixed relative to the front console. The assembly includes a gear fixed to the torsion bar. The assembly includes a rack including teeth meshed with the gear, the rack extending toward the panel.

Description

technical field [0001] The present disclosure generally relates to vehicle knee bolsters. Background technique [0002] A knee bolster is the lower portion of a dashboard in a vehicle. Knee bolsters are typically made of a padded structure to absorb energy when an occupant's knee strikes the knee bolster during a vehicle impact. Knee bolsters are typically positioned far enough from the seat to provide adequate leg room for the occupant, however, knee bolsters are also positioned close enough to provide protection during an impact. In the event of a vehicle crash, knee pads prevent "sneak skidding," when an occupant slides out of the seat, which can reduce the effectiveness of other safety features such as seat belts and air bags. Contents of the invention [0003] An assembly includes a front console having a panel. The assembly includes a torsion bar fixed relative to the front console. The assembly includes a gear fixed to the torsion bar. The assembly includes a r...
