Title: ADJUSTABLE STEERING COLUMN FOR MOTOR VEHICLES WITH ENERGY ABSORBER FOR VEHICLE CRASHES
Abstract:
The invention relates to an adjustable motor vehicle steering column (1) comprising a casing tube (11); a guide tube (2) which can be moved axially in the casing tube (11); a steering spindle (3) which is received by the guide tube (2) and is rotatably mounted about a rotational axis (4); an energy absorption element (10, 23) for absorbing impact energy during a vehicle crash, said energy absorption element being designed to be deformable, thereby absorbing energy, wherein the energy absorption element (10, 23) is arranged between the guide tube (2) and the casing tube (11); a deformation means (17) which is designed to deform the energy absorption element (10, 23) in the event of a vehicle crash; and an adjusting device (9) which is designed to axially move the guide tube (2) into an adjustment position and to fix the guide tube (2) in the adjustment position. The aim of the invention is to provide such a steering column with which an improved energy absorption is possible in the event of a crash and in the process the required components and costs can be minimized. This is achieved in that the absorbable impact energy is substantially independent of the component tolerances of the energy absorption element (10, 23) and the deformation means (17) such that the energy absorption reaches a substantially specified value.
