ABSTRACT:
An energy absorbing device for the steering column of an automotive vehicle comprises a pair of generally U-shaped straps made of relatively stiff, bendable, flexible strip material. One leg of each strap is connected to a bracket affixed to vehicle support structure. The other leg is connected to the steering column. In a collision, the straps resist movement of the steering column and gradually absorb energy to prevent excessive reaction forces of the steering column against the driver. A connection between the steering column and the bracket prevents vibration of the steering column during normal operation of the vehicle. This connection is releasable in response to initial vehicle impact to allow controlled movement of the steering column under the restraining influence of the straps.
