Abstract

The tension element position sensor includes three housing elements, wherein the two outer housing elements are configured pot shaped with a base towards a center housing component, wherein one element is the spring motor and the other is the rotation angle sensor. Thus the rotation angle sensor includes two Hall sensors, wherein an encoder magnet rotates as a function of the rotation of the winding drum opposite to the faces of the Hall sensors on the face side of one respective gear of two gears meshing with one another. Herein the arrangement of the gears and circuit boards in the receiver of this lateral housing component is of particular importance. Also the spring motor can be completely preassembled and stored in a closed manner.
