Abstract: A safety belt arrangement, for use in land vehicles or aircraft for securing the occupants thereof, has at least one belt reeling device with a self-locking blocking mechanism with a mechanical control for moving a locking member into the blocking position which prevents the belt from being pulled out further. In order to reduce the response times for the belt reeling devices, a computer is provided which determines the acceleration characteristics of the particular vehicle or aircraft and is coupled to the mechanical control of the belt reeling device, the locking member being moved into its blocking position or returned to its rest position by the mechanical control in response to a signal emitted by the computer.

Abstract: A safety belt system, especially for motor vehicles. The system includes a three-point safety belt, a self-locking belt reel-in mechanism mounted on a structural part of the vehicle, and a clamping mechanism for the belt strap of the safety belt. The clamping mechanism has at least one movable clamping jaw, and is movably disposed and guided on the structural part. A drive mechanism is provided for effecting movement of the clamping mechanism. To better adapt the geometrical path of the safety belt system to the body proportions of a strapped-in occupant, to thereby more reliably prevent endangering forward movement of the body of the occupant, the clamping mechanism is disposed, along with its drive, in the structural part of the vehicle in such a way that they are vertically adjustable.

Abstract: In the quick-release lock for a parachute, a measuring device (1, 2) is used for continuously measuring the distance of the parachutist from the surface on which he intends to land. In this arrangement, the measured distance values are repeatedly compared with predetermined values in a comparing device (3, 4, 7) during the descent. Only if the measured values agree with the predetermined values during the last section of the descent during, which the comparisons are carried out, is the parachute automatically released from the load, for example a person, when the distance 0 is reached.

Abstract: A safety belt system, especially for vehicles. The system has a three-point safety belt, a self-locking belt winding mechanism which is mounted on a structural part of the vehicle, and a clamping mechanism for the belt. The clamping mechanism is disposed on the structural part of the vehicle, and has at least one movable clamping jaw. The problem with a basic safety belt system of this type is that in particular the slack in the belt at the body of the strapped-in person, together with the belt elongation which additionally results due to the stretching of the belt, lead, upon activation of the clamping effect, to a forward shifting of the body, thus endangering the person who is strapped in. This problem is inventively solved by movably guiding the clamping mechanism on the structural part of the vehicle, and by providing a drive or control mechanism for the movement of the clamping mechanism.
