    • An axially adjustable steering device for motor vehicles comprises two jacket-tube parts, of which the inner jacket-tube part is displaceable telescopically in the outer jacket-tube part by means of a controllable drive, a worm gear received in a reception part pivotably mounted fixedly relative to the vehicle acting on an axial tooth-profile part on the inner jacket-tube part in a longitudinally displacing manner. The reception part is retained via a locking mechanism in an engagement position of the worm gear and tooth-profile part, and this locking mechanism is releasable in a controlled manner during a front collision, after which the worm gear is pivoted out of engagement with the tooth-profile part and the inner jacket-tube part is moveable into a position shifted furthest in the forward direction.
    • 用于机动车辆的可轴向调节的转向装置包括两个套管部分,其中内套管部分可通过可控制的驱动器可伸缩地位于外套管部分中,蜗轮容纳在可枢转地安装的接收部分中 固定地相对于车辆以纵向位移方式作用在内套管部分上的轴向齿形部分上。 接收部分通过锁定机构保持在蜗轮和齿形部分的接合位置,并且该锁定机构在前部碰撞期间以受控的方式可释放,此后蜗轮枢转脱离与 齿廓部分和内套管部分可移动到向前移动最远的位置。
