ADJUSTABLE STEERING COLUMN FOR MOTOR VEHICLES WITH ENERGY ABSORBER FOR VEHICLE CRASHES

摘要

An adjustable motor vehicle steering column may include a casing tube, a guide tube that is axially movable in the casing tube, a steering spindle that is received by the guide tube and is rotatably mounted about a rotational axis, an energy absorption element that is disposed between the guide tube and the casing tube and deforms and absorbs impact energy during a vehicle crash, a deformation means that deforms the energy absorption element during the vehicle crash, and an adjustment device for axially moving the guide tube into an adjustment position and fixing the guide tube in the adjustment position. The absorbable impact energy may be substantially independent of component tolerances of the energy absorption element and the deformation means such that the energy absorption reaches a substantially predefined value.”
