Abstract: A seat belt system is disclosed having a triggering element that is set to a certain deceleration value and the signal of which, via a lock switch that is opened when the latch of the seat belt is engaged and via a pull switch closing at a certain pulling force that is applied to the seat belt by the user, triggers one indicating element respectively, such as a fuse, according to the position of the switches. The lock switch and the pull switch as well as the indicating elements are inaccessibly arranged in the belt buckle. From the combination of triggered or untriggered indicating elements, it can be concluded whether the seat belt was put on functionally correctly or had not been put on and whether manipulations took place at the belt buckle by means of electrical signals or mechanical forces.

Abstract: A steering apparatus for a motor vehicle has a steering gear connected to a first set of vehicle wheels, and a selectable auxiliary steering gear connected to a second set of wheels. The steering gear for the first wheel set is connected to a steering wheel and includes a hydraulic servo mechanism which provides steering assistance to the steering gear when the force required to turn the steering wheel exceeds a predetermined limit. A hydraulic pressure transmitting device is attached to the gear output of the steering gear and is hydraulically connected to the auxiliary steering gear. The pressure transmitting device transmits hydraulic pressure to the auxiliary steering gear, when auxiliary steering is selected, which varies in correspondence with movements of the gear output of the steering gear and which is independent of the pressure supplied to the hydraulic servo mechanism.
