Abstract

A device (10) for length adjustment has a bar-shaped component (12) with an external profiling (14) which is received in a receptacle (16) of a base body (18). The base body (18) has at least one profiled segment (22, 24) which, under the influence of an axially slidable hollow element (28), is shifted into a locking position at a first axial position of the hollow element (28), in which the base body (18) and component (12) are axially rigidly coupled, and is shifted into an unlocking position at a second axial position of the hollow element (28), in which the base body (18) and component (12) are axially displaceable relative to one another. The device (10) is distinguished in that a locking member (34) with two locking member positions (36, 38) is provided, in which in the first locking member position (36), the hollow element (28) is retained under the influence of spring bias in the first axial position (30), and in the second locking member position (38), the hollow element (28) is retained by the locking member (34) in the second axial position (32), counter to the influence of the spring bias (FIG. 2).
