Device for longitudinal adjustment, in particular of a remote control in motor vehicles

The invention relates to a device for longitudinal adjustment, in particular of a remote control in motor vehicles, having a substantially bar-shaped component that has an external profiling, for example a set of teeth. The component for example is a tension or pressure rod, sleeve or bar. The component is at least partly received in a receptacle of a base body which optionally has a pivotal connecting piece or similar binding. At least one profiled segment is guided radially displaceably on the base body by axial movement of a hollow element such as a sleeve or locking sleeve on the base body. The hollow element is spring biased in a first axial position to hold the profiled segment in a locking position in which the base body and component are rigidly coupled in the axial direction. Movement of the hollow element to a second axial position against the spring bias transfers the profiled segment to an unlocking position in which the base body and component are displaceable relative to one another in the axial direction. A device () for length adjustment has a bar-shaped component () with an external profiling () which is received in a receptacle () of a base body (). The base body () has at least one profiled segment () which, under the influence of an axially slidable hollow element (), is shifted into a locking position at a first axial position of the hollow element (), in which the base body () and component () are axially rigidly coupled, and is shifted into an unlocking position at a second axial position of the hollow element (), in which the base body () and component () are axially displaceable relative to one another. The device () is distinguished in that a locking member () with two locking member positions () is provided, in which in the first locking member position (), the hollow element () is retained under the influence of spring bias in the first axial position (), and in the second locking member position (), the hollow element () is retained by the locking member () in the second axial position (), counter to the influence of the spring bias (FIG. 2).
