A multilayer material for sliding surface bearings comprises a metal backing layer, a sintered porous bearing layer of a bearing metal, and a low-friction layer consisting of a mixture of PTFE and 5 to 30% by volume metal filler, and fills also the pores of the bearing layer. To reduce the wear the mixture of PTFE and metal filler contains also 5 to 40% by volume PVDF.

Collision-protection devices for vehicle passengers, are disclosed which include a gas cushion which is connected to a gas generator and inflates under sensor control in the event of an accident and hence protects the body of a vehicle passenger from a collision causing injury, e.g., against the instrument panel or windscreen. The gas cushion has, in this instance, one or more escape openings. According to the invention, the escape opening points towards an open cover flap when the gas cushion is inflated, which cover flap, in the closed state, covers the folded-up gas cushion. Only once a predetermined pressure has been exceeded does the cover flap free the escape opening to enable gas to be discharged in an escape flow distributed over an area of the gas cushion surface.

An inflatable airbag to protect the occupants of a vehicle from an impact on parts in the vehicle passenger compartment is constructed such that a joining seam of two fabric ends of the airbag is provided in the vicinity of an opening made in the bag fabric. The fabric ends are overlapped to such a degree that together they form the complete edge region around the opening and the opening itself.

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.

A method and apparatus for monitoring the yarn tension at each of a plurality of yarn processing stations is disclosed and wherein the mean value of the monitored tension is continuously determined at each station, and the differential between the monitored value and the mean value is also continuously determined. A first alarm signal is generated whenever the mean value leaves a predetermined tolerance range, and a second alarm signal is generated whenever the differential value leaves a second predetermined tolerance range. These alarm signals are logged, in both number and duration, to provide an indication of the quality of the yarn.
