摘要:
Tripping apparatus in vehicles for an occupant protection apparatus in impact restraining systems is provided with a test circuit which permits a testing of the evaluation circuit and of the switching stage of the tripping apparatus by means of an alternating voltage signal without interrupting the functional readiness of the apparatus. The test circuit consists of a series arrangement of a filter, a maximum value rectifier and an integrator and is inserted between the output of the switching stage and the input of the evaluation circuit.
摘要:
A voltage supply device for a passenger protection installation in a motor vehicle, especially for an air bag, by means of which the passenger protection installation is kept fully operational even at small vehicle battery voltages by means of a low-power voltage converter which is connected exclusively in a control circuit.

With a sun visor comprised of a cushioned tube and housing swivel bearings at both ends, the tube is designed as an energy absorption member for eliminating head injuries due to an accident, and is designed as the only connection between the swivel bearings.
摘要:
A device for actuating a safety device, in particular a roll bar in a motor vehicle. The device includes a first sensor which is actuated when a vehicle acceleration exceeding a predetermined limiting value occurs and which generates a switch signal for a release device to activate the roll bar. The device also includes second and third sensors which control switches when both at least one wheel suspension is fully extended and the vehicle is tilted about either a longitudinal or transverse axis, so as to actuate the safety device during even relatively slow overturns.

An anti-collision cushion is disclosed for the occupants of a motor vehicle. Known anti-collision cushions are constructed with a central part which is connected to two side parts of equal size. A tearing fold which reduces the volume capacity, and which is formed by a rip seam, is provided on the surface of the central part. In the deployment phase an expansion occurs with high velocities in the region of the side parts, which may result in injuries to the occupant in some circumstances. In the novel anti-collision cushion the rip seams connect the connecting seams which are contiguous in the region of the tearing fold between the central part and the side parts. A reduction of the expansion and of the expansion velocity, particularly in the region of the side parts, is thereby achieved.

A device for recognizing a child's seat which is strapped to the front passenger's seat of a motor vehicle is provided. Such a device is required in order to inhibit release of a front seat passenger's side airbag when a child's seat is strapped on the front passenger's seat. An identification carrier, for example, an electrical tuned circuit or an intelligent data carrier, which attenuates an electromagnetic measurement field in a characteristic manner, is fitted to the child's seat. The presence and, possibly, also the type of child's seat used can be recorded.
摘要:
A receptacle arrangement for an air bag which protects a vehicle occupant from an impact onto parts of the vehicle interior, has a covering which is fixed to a base plate and covers an air bag container. The covering folds out along a hinge axis of a hinge in the edge region of the air bag container during the unfolding of the air bag, after which it exposes a container aperture for the passage of the bag fabric into an inflated position in front of the vehicle occupant. The covering has, in addition to the first hinge, two further hinges which bound the first hinge on both sides, are approximately perpendicular thereto and have a clearance from the lateral edges of the covering. Thereby, two lateral covering flaps are formed which subdivide the swivellable covering.
摘要:
An impact protection device for an occupant of a motor vehicle having an air bag. The air bag is arranged folded up in a receptacle fixed to the vehicle and can be inflated by a filler gas. An air bag surface facing a vehicle occupant being limited in its movement towards the vehicle occupant in the center region by a restraining device. The restraining device is formed by a cover plate over the receptacle which is connected to the vehicle by short limiting straps, so that on unfolding the air bag extends around the periphery and in the direction of the vehicle occupant in front of the cover plate.
摘要:
A gas cushion on the passenger side for motor vehicles, especially for passenger motor vehicles, includes two mutually oppositely disposed approximately trapezoidally shaped surface or boundary areas. The unique shape of the cushion provides a particularly safe protection effect in the critical upper impact area without increase of the overall volume of the gas cushion. One of the trapezoidally shaped boundary areas serves as impact surface facing the passenger while the other trapezoidally shaped boundary area includes at least one opening serving the gas admission. The gas cushion is so arranged in the motor vehicle that the trapezoidally shaped boundary areas taper from top to bottom.
摘要:
There is described a machine for the winding of tubular products, preferably with tensioned wires (8), including at least one disc (51-52) assembled to rotate on a base structure (2), a motor (9) adapted to drive the rotation of the disc (51-52, 101-103), a plurality of coils (3) assembled to rotate on supports (4) integral with said disc (51-52) and tensioning means (18, 30-31, 40-42), adapted to maintain the tension of the wires (8) constant during the winding of the tubular product (20). Said machine also includes a plurality of driving motors (5) associated to respective coils (3), adapted to feed the wires (8) and operating means (70) and potentiometers (19), adapted to control the unwinding speed of the wires (8) from the coils (3), which are driven by the motors (5).
