Embodiment Construction

[0024] figure 1 A cross-sectional view of the overall structure of the safety steering column 10. The safety steering column can be adjusted in length and inclination with the clamping devices 100 and 100' which will be described in detail below, and at least one of the clamping devices can also achieve the collision protection function .

[0025] The safety steering column 10 shown in the figure has a steering handle 200 or a steering wheel mounted on a steering column or an outer tube 110 for a steering shaft, and the steering shaft extends into the clamping device 100. The steering column 10 and the clamping devices 100 and 100' arranged on the steering column are connected to the vehicle body through a lever mechanism 150, wherein the lever mechanism 150 and the clamping device 100' cooperate to adjust the inclination of the steering column 110 . The other clamping device 100 can adjust the outer tube 110 and the steering column longitudinally or axially. The two clamping d...

Abstract

The invention relates to an adjustable safety steering column for a motor vehicle, comprising at least one clamping device (100), which has a leg spring (130) for fixing the length of the adjustable steering column. The leg spring clamps onto a casing tube (110) for a steering shaft (110) at a position that can be adjusted by releasing the leg spring (130), the casing tube being inserted in the clamping device (100). At least in the vicinity of one end of the leg spring (130), at least one stop element (141, 142, 143) is arranged, against which the leg spring (130) stops in the event of an axial movement (V) of the casing tube (110) toward the accommodating tube, whereby the winding of the leg spring (130) assumes a tilted position that can be limited. Thus, an adjustable crash function is implemented.

Description

Technical field [0001] The invention relates to an adjustable safety steering column as described in the preamble of claim 1 and a clamping device for adjusting the steering column as described in the preamble of the parallel claims. The invention specifically relates to a safety steering column and a clamping device, both of which can conveniently adjust the position of the steering column at least in the axial direction and provide collision protection functions. Background technique [0002] The safety steering column in the prior art generally uses at least one clamping device to adjust the position of the steering column. [0003] DE 102008036548 describes a steering column whose length and inclination can be adjusted by means of a clamping device. Each clamping device has an elastic element preferably implemented as a torsion spring or a coil spring, which expands after being applied with a force, but is normally tightened, so as to apply a clamping force to the component gu...
