Abstract

Locking arrangement for locking a first element which is movably mounted in a first direction, by means of a second element which is movably mounted in a second direction transversely with respect to the first direction. First element has a toothed contour with at least two teeth and a tooth gap which lies between. Second element has a projection which has a projection length which is shorter than the tooth gap length. The projection can be introduced into tooth gap when there is movement in the second direction, to lock the first element. Each tooth has a face which points towards the second element and has a first contour. Projection has a face which points towards the first element and has a second contour. First and second contours are matched to one another so that the projection is deflected by the teeth from becoming inserted into tooth gap if first element moves faster than a predetermined locking speed and slower than a maximum speed of first element.
