Abstract: Automatically locking belt roll-up device for safety belts, especially for motor vehicles, with a belt shaft which is rotatably supported in a roll-up device housing. The belt shaft has ratchet teeth and is under the action of a rewinding spring. A spring-loaded pawl is automatically locked with the ratchet teeth by force of the spring after the belt is put on. The pawl is additionally under the action of a delay device, which is released only after a predetermined time phase for effecting the locking process.

Abstract: Mechanism in roll-up devices for safety belts in motor vehicles, where the safety belt which, addressed by one or more danger sensors, can be blocked via a belt shaft, is stressed in tension in the winding-up direction of the belt shaft by the force of a spring, and where, through control gates of plate cams, a locking device for the belt shaft is activated from the rest position against the elastic rolling-up spring force within a small range of rotation of the belt shaft in the pulling direction of the belt shaft. The belt shaft and two plate cams for influencing the locking device are in planet-gear-like functional connection with each other, where the antifriction bearing elements are arranged in a planet-gear-like manner and the belt shaft as well as the two plate cams are designed and arranged in a sun-gear-like and planet-gear-cage-like manner.

Abstract: Belt strap-clamping device for safety belts in motor vehicles which has a roll-up device with a belt strap which is rolled-up on a belt drum, and which can be rolled out against a spring-force. The belt from the roll-up device is partially wrapped around a deflection member with an arched deflection surface, hinged around an axis, and arranged after the belt drum. The belt strap works in conjunction with a clamping surface which is fixed in the fitting, such that the deflection member is moved when an increased force is applied, and the belt strap is clamped between the clamping surface and the deflection member. At a normal pulling out of the belt the deflection member is held at a distance from the clamping surface by the force of a spring. The deflection surface is formed by a sleeve-like deflection member, which is during normal operation freely rotatable on an eccentrically supported roller, which can be displaced on a predetermined angular path in relation to a clamping surface.
