ABSTRACT:
This invention relates to a coupling of the ball-and-socket joint type between two objects. Connected to the one object, which may be a driver's seat in a working vehicle is a joint socket and a joint ball with a gap between them. Connected to the other object, which may consist of a base for a driver's seat, for example, is a coupling element in the form of a spherical shell disposed in the gap between the joint socket and the joint ball. The latter are pressed towards one another by means of powerful cup springs so that the spherical shell is locked firmly and the two objects are thus located in relation to one another. The grip of the spring force can be cancelled by means of a tightening element connected to the joint ball, as a result of which the coupling becomes movable again so that new positions can be adopted. The coupling can be used in various connections where it is desired to adjust two objects in relation to one another simply, securely and quickly.
