The invention relates to a safety steering system for motor vehicles, especially for passenger cars, with a steering column arranged in an Ilantel tube.

ü to reduce the risk of injury to the Palirer in the case of Un -.- T .-. len The aim is to make the steering column flexible in its longitudinal direction.

The invention is based on the object of the known steering arrangements without significant effort in security steering. The conversion is already under way

The invention consists in that the jacket tube nit deformation element or a deformation point is provided and the steering column consists of two aligned cables, the one that opens in the event of overload, or at least a shifting of the parts enabling connection point are assembled. To even when facing slightly sideways To allow poking to give way, it is beneficial, though the deformation element or the Deformations'stelle and the Connecting parts in the length of the bulkhead of the motor vehicle lie"

In a structurally simple manner, the deformation element can be made from an insert provided with an annular bead into the dumbbell tube exist. To further weaken the defomation element while avoiding the penetration of dirt and moisture, the insert provided with the annular bead can additionally have bores which are covered with sealing means, preferably elastic hoses. The deformation element however, it can also consist of an insert piece that widens conically from the bulkhead towards the dumbbell tube exist, which is provided with recesses, preferably longitudinal slots, which are covered with sealing means are.

The security line essentially orders from a jacket pipe 1 and a steering column 2, which at its upper end over a hat 5 is connected to a steering wheel 4 and with her lower end connected to the steering gear, not shown is. The steering column 2 is mounted on the upper end of the dumbbell tube 1 in the manner shown.

At its lower end, the dumbbell roll 1 has an insert piece 5 designed as a deformation element which is fastened to the bulkhead 7 via an annular flange 6. In Fig. 1, two different embodiments of the insert 5 are shown. The insert 5 'shown in the upper half has an annular bead 8 and it is provided with bores 9 in its cylindrical veil. These bores 9 are sealed against the ingress of dust and moisture by means of a hose-shaped seal 10, which is preferably made of rubber or plastic. ^{The insert 5 tf} shown in the lower half of the pig. 1 widens conically from the ring fleece 6 arranged on the bulkhead 7 to the lä.ntelrolir 1.

The two-part steering column 2 has a connection point at which the two 'x' parts provided with bevel cuts are joined together are. The surfaces of the two slope centers are

As a result of an accident, an impact load is placed in the direction the steering column 2, the hooves 13 are widened or destroyed, so that the two parts of the steering column against each other can move. In that both the deformation element 5 as well as the connection point are arranged in the vicinity of the bulkhead 7, there is also a Hachgiebig-1-cit the safety steering for bumps that are not exactly in Take place in the longitudinal direction of the steering column 2 and the jacket tube 1. Such oblique impacts are much more common in accidents ice directly in the direction of the steering column 2 and the jacket tube 1 taking place, since this would give me a direct, frontal Collision are conceivable.

A further, advantageous embodiment of the connection point of the two cables of the steering column 2 is shown in FIGS. 3 and 4 shown. Here, the slightly angled and parallel ends 14 of the two ropes are by means of a 3enraubklemme 15 held together. When overloaded, the Suffering sheets of the screw terminal 15 bent up, so that the both! 'hurry of the steering column can move against each other, jjüi diener embodiment it is structurally simple possible to compensate for length tolerances of the two ropes of the steering column, by using different sized screw terminals
