Abstract: The invention proposes a device for influencing the movement of furniture parts (1, 2) which can be moved relative to one another, having a movement-influencing unit which comprises an installation housing, in which movement-influencing coupling means are accommodated such that they can be displaced at least in a translatory manner, and having a coupling element, to which the coupling means are connected in the operating state. In order to provide a device which is of space-saving construction and is comparatively straight-forward to install, the movement-influencing unit is designed such that, by virute of a relative movement between the coupling means and the coupling element in a displacement direction of the coupling means, the coupling means can be coupled to the coupling element to produce a connection which has a predeterminable coupling force. Also proposed are a drawer guide and a production method.
