Abstract
A crash system for the steering column in a motor vehicle, in which two tube ends are connected to one another by an insert which clamps the two tube ends to one another up to a predetermined axial load. This insert is a tolerance ring, whose cross-sectional profile is compressible. An adjustable clamping device surrounds the outer tube end and acts radially.
Claims10
A crash system for a steering column in a motor vehicle, comprising:
- a first tube with a first tube end;
- a second tube with a second tube end, said first tube end engaging said second tube end, with said second tube end being radially outwardly disposed relative to said first tube end;
- insert means for connecting said first tube end and said second tube end to one another so that said first and second tubes are relatively movable at a predetermined axial load, said insert comprising a tolerance ring having a compressible cross-sectional profile;
- and
- clamping means surrounding a portion of said second tube end, said clamping means for adjustably applying a radially acting clamping force onto said second tube which then applies said radial clamping force onto said tolerance ring.

A safety steering column for a motor vehicle, comprising:
- a first tube with a first tube end;
- a second tube with a second tube end, said first tube end engaging said second tube end, with said second tube end being radially outwardly disposed relative to said first tube end and having means for being axially compressible;
- clamping means surrounding said second tube end for adjustably applying a radially acting clamping force to said second tube;
- a tolerance ring positioned radially between said first and second tubes at an axial position of said clamping means, said tolerance ring having a compressible cross-sectional profile, said clamp means radially compressing said second tube end and said tolerance ring onto said first tube so that said first and second tubes are only relatively movable above a predetermined axial load.
