Abstract
An adjustable steering device for motor vehicles has a steering spindle which can be axially displaced in at least one jacket tube by way of an adjusting device. The adjusting device adjusting device is provided with an operable adjusting element which holds the steering spindle and releases it for the displacement. The adjusting element includes at least one pressure segment which is held by at least one elastic tensioning element in a receiving ring embracing the protective steering tube. It has a toothing which can be brought into a fixing and a displacement position by a corresponding toothing on a protective steering tube by way of at least one tensioning device. As a result, an adjustable steering device is provided which ensures a simple and secure axial displacement and fixing while the behavior in a crash is good.
Claims11
A steering assembly for motor vehicles comprising:
- a steering spindle,
- a protective tube surrounding said spindle,
- a jacket tube surrounding the protective tube, said jacket tube being fixed in position when in an in use position in a vehicle,
- a rotatable spindle nut threadably connected with a threaded portion of the protective tube so as to axially adjustably move the protective tube and spindle in response to rotation of the spindle nut,
- a motor drivingly connected to the spindle nut,
- and a tubular energy absorbing deformation element interposed between the spindle nut and an end of the jacket tube.
