Abstract

A steering spindle (1) has a thin-walled container (5) which is filled by an incompressible flowable material (7). In the event of a crash, the container (5) is opened up by means of a, for example, pyrotechnic device (13). As a result, the flowable material (7) emerges and the container (5) deforms, whereby the forward vehicle intrusion is uncoupled from the behavior of the steering column.
