LENGTH-ADJUSTABLE STEERING ACTUATION UNIT FOR A MOTOR VEHICLE WITH A SUPPORT AND A STEERING COLUMN

摘要

The invention relates to a length-adjustable steering actuation unit for a motor vehicle, which comprises a) a support (20) to be fixed to the motor vehicle; b) a steering column that is rotatable about a longitudinal axis (22) and has an upper steering tube (24) and a lower steering tube (26); and c) an adjustment device for adjusting the distance of the upper steering tube (24) in relation to the lower steering tube and the support (20). The invention is characterized in that a deformable element is provided between both steering tubes (24, 26), which is shortened in the event of an accident so that the total length of upper steering tube (24) and lower steering tube (26) is shorter after an accident.
