Abstract:

A method for adjusting a first force applied to a movable element in a first position of the movable element by a force applying device, the force applying device applying a second force to the movable element in a second position of the movable element. The method includes connecting the movable element and a base element with a scissors-type linkage; mounting the force applying device to the scissors-type linkage at a first mounting point; mounting the force applying device to the base element at a second mounting point; and moving at least one of the first and the second mounting points along a constant force curve, so that the second force remains constant as the first force is adjusted. A device for adjusting a first force applied to a movable element in a first position is also provided.
