ABSTRACT:
A support for the steering column of an automobile has capsules for dampening vibration while the automobile is in motion. A bracket on the steering column has flanges which are clamped between the capsules. The bracket flanges are frictionally held by the capsules but will break free of the frictional hold to permit collapse of the steering column in the event of a collision. The flanges and capsules are tapered so that when the driver is thrown forward against the steering wheel upon vehicle impact, the initial collapse of the steering column reduces the frictional hold to zero, thus eliminating frictional drag during further collapse of the steering column.
