Abstract

Door hinge with a locking device based on a field force, including a cylinder divided by a piston into working spaces that are filled with an operating medium whose viscosity can be changed by means of a field force. The working spaces are connected to one another by at least one flow connection that is subject to the influence of a field force generating element. The door hinge is designed as a pivot bearing, wherein the cylinder takes the form of a bearing eye and the piston takes the form of a rotary piston with at least one blade.
