Abstract
The invention relates to a device for limiting the number of revolutions of a shaft or the like, especially for the rotatable drive of sliding roofs in automobiles, which comprises an eccentric disc securely mounted on the shaft and having an externally toothed ring rotatably mounted on its circumferential surface, which ring is surrounded by an inner toothed arrangement situated fixed in a rosette block concentric to the shaft axis, the tooth root radius of which exceeds, by approximately the eccentricity of the eccentric disc, the tooth tip radius of the toothed ring, whereby abutment means for the end limiting positions of the shaft after a predetermined number of rotations has been reached are connected to on the one hand the tooth ring and on the other hand the rosette block.
