  • Locking device of a motor vehicle for securing a displaceable motor vehicle component
    Patent number: 8806717
    Abstract: A locking device for securing a motor vehicle component which is displaceable relative to a motor vehicle structure and which may be secured by means of the locking device within a displacement range in a respective position of rest reached by displacement is provided. The locking device comprising at least one first frictional element and at least one second frictional element, which is moved relative to the first frictional element upon displacement of the motor vehicle component and thereby may slide with a friction surface along a friction surface of the first frictional element under sliding friction conditions and which, in a respective position of rest of the motor vehicle component, with its friction surface bears against the friction surface of the second frictional element under static friction conditions. A flowable additional medium is provided which may be brought, upon a relative movement of the frictional elements, between their friction surfaces.
