Spring-operated spindle position-limiter for power-operated door, window or hatch, has worm drive with position-limiter coupled to surrounding gear housing, where the power output is a given relationship to spring tension

摘要

A power-operated door, window or hatch has a worm drive (2) with a position-limiter (3) coupled to the surrounding gear housing. On reaching this limitation, the power applied is regulated by a spring element (4). The power output (8) is in a given relationship to the spring tension.
