Abstract
Abstract A safety steering arrangement for motor vehicles in which a plastically deformable deformation member is arranged between the steering wheel and the upper end of the steering shaft; an upper part of the steering shaft is thereby so supported at a fixed vehicle part that it can be pivoted into such a position under the influence of forces engaging at the steering wheel which are smaller than the forces necessary for the deformation of the deformation member, that its center longitudinal axis extends approximately horizontally or the plane of the steering wheel extends approximately vertically while means are provided in the connection of the steering shaft which enable the pivoting of the upper part of the steering shaft with respect to a further part thereof.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
155 words
A safety steering for motor vehicles which includes a steering shaft means, a steering wheel and a deformation means plastically deformable in case of an impact of the driver, said deformation means being arranged between the steering wheel and the upper end of the steering shaft means, characterized by means for mounting an upper part of the steering shaft means at a fixed vehicle part in such a manner that it can be pivoted under the influence of forces engaging at the steering wheel which are smaller than the forces necessary for the deformation of the deformation means into such a position that its center longitudinal axis extends approximately horizontally or the plane of the steering wheel extends approximately vertically, and in that further means are provided in the train of the steering shaft means which enable the pivoting of the upper part of the steering shaft means with respect to a further part thereof.
Claim 2
Dependent Claim
155 words
A safety steering for motor vehicles which includes a steering shaft means, a steering wheel and a deformation means plastically deformable in case of an impact of the driver, said deformation means being arranged between the steering wheel and the upper end of the steering shaft means, characterized by means for mounting an upper part of the steering shaft means at a fixed vehicle part in such a manner that it can be pivoted under the influence of forces engaging at the steering wheel which are smaller than the forces necessary for the deformation of the deformation means into such a position that its center longitudinal axis extends approximately horizontally or the plane of the steering wheel extends approximately vertically, and in that further means are provided in the train of the steering shaft means which enable the pivoting of the upper part of the steering shaft means with respect to a further part thereof.
Claim 3
Dependent Claim
17 words

Claim 4
Dependent Claim
42 words
A safety steering according to claim 1, characterized in that the further means includes a torsion resistant deformation member arranged in the train of the multi-partite steering shaft means, said deformation member operatively connecting two parts of said multi-partite steering shaft means.
Claim 5
Dependent Claim
17 words
A safety steering according to claim 3, characterized in that the deformation member is of corrugated construction.
Claim 6
Dependent Claim
