Abstract: Restraining system, especially a passive restraining system, for motor vehicles wherein one end of the belt is slideable in a slider track, preferably arranged above the vehicle door, and can be locked at the end of the track behind a securing element which extends into the slider track. An inertial mass sensor activated when an acceleration or tilting force exceeds a predetermined value, results in movement of the inertial mass in the direct path of the movable securing element causing blocking of its movement and retaining it in locked position to lock the belt end.

Abstract: Automatic roll-up device for retarding movement of a safety belt when a predetermined acceleration or deceleration is exceeded, combined with a braking- or clamping device in which the retarded belt is arrested. The roll-up device has a retarding mechanism which blocks a control disc causing braking of the belt roller. This causes a change in movement of the belt which activates the braking- or clamping device. The latter immediately arrests movement of the belt and absorbs any pulling forces which would have been exerted against the retarding mechanism. The roll-up device can be of light-weight construction.

Abstract: Device for braking and/or blocking of load carrying flexible pulling means such as belts or ropes having a braking roller partly wrapped by the load carrying flexible pulling means. The roller can move with respect to a clamping surface when the pulling means exerts a tangential force on the braking roller. A clamping surface is disposed adjacent the pulling means near the braking roller. Braking roller movement effects clamping of the pulling means against the clamping surface.

Abstract: A retightener for safety-belt automatic wind-up devices having an energy converter having a charge, which when activated in the case of danger, the explosive pressure of the fired charge acts on a retightening element which tightens the safety-belt around the body of the motor vehicle passenger. The retightener of the invention has an intermediate liquid medium transmitting the explosive pressure of the charge arranged between the charge and the retightening element.

Abstract: Braking device for safety belts which have a braking system ahead of the braking device, which latter has movable brake roller partly wrapped around by the belt, a stationary clamping bar disposed adjacent one side of the belt, and a movable arresting element. Upon activation resulting from a belt pull which exceeds a predetermined force, the brake roller is moved out of position against the arresting element which latter moves toward the stationary pad to cause clamping of the belt and which also arrest the brake roller by contact therewith.

Abstract: A redirecting device for a safety belt for use in motor vehicles, in which one end is rolled up on an automatic winder and the other end of the safety belt has a fitting for connecting the belt to a lock. The redirecting member is a hollow rotatable cylindrical member, wider than the belt, mounted on an axle supported by the legs of a bracket. Roll elements are disposed at the ends of the rotatable member to support it and permit it to rotate freely. Additional roll elements which project beyond both sides of the wall of the rotatable member are disposed in the central region of the rotatable member. This has the advantage of a smaller ratio of retraction force to pull-out force of the belt.

Abstract: Safety belt roll-up device with a locking pawl mechanism to engage locking teeth of a locking wheel in fixed connection with the belt shaft. The pawl mechanism has a double locking pawl having two pawl levers, rotatably mounted on a common pivot axis. Each lever has a pawl tooth for engagement with the locking wheel. The two pawl teeth are spaced a distance which is different than the pitch of the locking teeth of the locking wheel or a multiple thereof. A release mechanism, upon the vehicle exceeding permissible limit of acceleration or deceleration, activates the pawl to move into locking engagement. By virture of the two pawl levers in the locking mechanism combination of the invention, a pawl tooth hitting the point of the tooth of the locking wheel and bouncing off, results in immediate engagement of the other pawl tooth with a locking tooth of the locking wheel.

Abstract: Belt lock for a safety belt with a spring-operated locking catch with hooked part engaging a plug-in tongue. A hand-operated member has a locking part in fixed connection. The locking part is disposed in the path of motion of the hooked part preventing release of the tongue unless the member is pressed by hand to move the locking part out of the path of motion. The locking part is movable along the plug-in axis; and the locking part in the closed position couples with the locking catch.

Abstract: Belt-lock and plug-in tongue for a safety belt having a locking mechanism with two locking latches for locking the tongue, tensioned against each other by a spring, and with one locking latch disposed on each side of the plug-in tongue. A hand-actuated member is movable against disengaging means of the locking mechanism to simultaneously move the two locking latches out of engagement with the tongue to permit removal of the tongue from the lock-housing. This assures symmetrical absorption by the belt lock through the latches of forces introduced by the belt system, and also equal distribution of the pulling forces to both locking latches so that the effective forces at each locking latch are halved.

Abstract: Safety belt roll-up device with a release mechanism which in case of danger activates a control disk and locking means which block the belt shaft. A cam having an actuating dog for actuating the locking means is associated coaxially with the control disk and rotatable relative thereto. A spring holds the dog in a predetermined starting position relative to the control disk, which spring can be deflected resiliently relative to the control disk in opposite directions of rotation. Because of its ability to be deflected in oppsite directions, a single type roll-up device will serve where previously right and left devices are needed.
