Abstract:
1. Apparatus for irrotationally locking a motor-vehicle steering shaft comprising a locking bolt axially reciprocable within a housing between a locked position and a release position, said locking bolt being fixable in its locked position by a securing pin which is axially displaceable in said housing and which is biased by a spring towards the locking bolt, said spring having a side thereof that is remote from the locking bolt; said securing pin in its locking bolt fixing position cooperating with a lateral recess of the locking bolt such that upon removal of a housing portion that is fitted with a retaining arm retaining the securing pin against the spring load of said spring, the securing pin is released to cooperate with said recess to fix the locking bolt in its locked position; said retaining arm extending through a matching cavity in the housing and normally engaging the securing pin on the side of the spring remote from the locking bolt in order to retain the securing pin against the bias of said spring, and an end of the securing pin remote from the locking bolt being located on that side of said cavity of the housing which is adjacent to the locking bolt when an other end of the pin closer to the locking bolt engages the recess of said locking bolt to fix the locking bolt; said securing pin being neither visible nor accessible through the cavity when the cavity is unoccupied by said retaining arm and in the open state, and when the securing pin is moved to its locking bolt fixing position with said other end closer to the locking bolt engaging the locking bolt recess.
