Position sensor, sensor arrangement and rehabilitation device

Position sensor comprised of

• a holder (3);
• a firmly with the holder (3) connected force measuring device (5);
• a firmly with the force measuring device (5) connected winding device (6, 16) with a drive (7), featuring an electric motor (7), the winding device (6, 16) set up to unwind and wind the cable (8) and for the determination of an unwinding length of the unwound cable (8);
• and
• a with the holder (3) firmly connected guiding device (11) featuring a centering device (13) for a defined, fixed-direction passing through of the cable (8), a gimbal-mounted outlet apparatus (15) for a variable-direction passing through of the cable (8) and a position sensor to determine an angular position of the outlet apparatus (15);
• whereas the position sensor (1, 2) is designed to determine the position of a predefined point of the cable (8) relative to the holder (3) based on the determined angular position and the unwinding length;
• and
• whereas the electric motor (7) is set up to act on the cable (8) with an adjustable tensile force, which is adjusted based on a force which acts on the holder (3) via the cable and which is determined by the force measuring device (5).
