摘要:
An airbag system for protecting the occupants of an automotive vehicle during collisions, the airbag system including airbags for the driver and front-seat passenger, and a sensor system for detecting the increase in deceleration of the vehicle during a collision and for triggering controlled inflation of the airbags in accordance with the detected increase in deceleration. The airbag associated with the front-seat passenger being inflatable in two stages, the first inflation stage being triggerable in response to an output signal from the sensor system generated when the detected increase in deceleration is equal to or greater than a first threshold value, and the second inflation stage being triggerable in response to an output signal from the sensor system generated when the detected increase is equal to or greater than a second threshold value which is higher than the first threshold value. The airbag associated with the driver being inflatable only when the second threshold value has been equalled or exceeded. The sensor system is provided with a delay arrangement for delaying at least the triggering of the second inflation stage with respect to the triggering of the first inflation stage by a predetermined delay time period.

An inflatable impact cushion for passengers of a motor vehicle, which in case of an accident is adapted to be selectively filled with the available gas by the increasing pressure by means of several sequentially triggerable ignition stages depending on the strength of the deceleration; in the starting condition, a portion of the protective cushion is separated off by a seam or the like, while the seam or the like is destroyed by the increasing pressure in such a manner that in the end condition the entire volume of the protective cushion is available.
摘要:
A covering for a folded gas cushion which is adapted to fold open by pivoting down, and which is provided with a reinforcement embedded in a padding layer; the reinforcement consists of a very strong synthetic plastic fabric that, prior to the foaming of the padding layer, is connected, for example, by gluing with a deformable lower fastening part; an anchoring for the covering is produced by a groove- and spring-like cooperation of at least one section of a boundary edge of the covering with an adjoining fixed vehicle part.
摘要:
An impact absorbing device constructed as a hollow body member and extending in a vehicle transverse direction within in an impact area of knees of a driver and co-driver of a motor vehicle. The impact absorbing device has an impact engaging surface facing the knees, with the surface having a rounded-off cross sectional profile and vertically extending corrugations so that the member yields only locally upon engagement by the knees.
摘要:
A sensor triggerable by deceleration forces, especially in motor vehicles, which accommodates within a housing a mass that is held with prestress; when deflected the mass is received by the bottom of the housing interior, whereby the interior space of the housing is subdivided into chambers by means of upwardly projecting partition walls which hold fast the deflected mass.

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.

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.

A passive restraining system for an automobile provides a means, in the event of an automobile accident, for inflating an air bag system on the driver's side at a lower threshold speed if the driver is not wearing a seat belt, and at a higher threshold speed if the driver is wearing a seat belt. This system, however, allows a second air bag system to inflate for protecting the front seat passenger in the event of an accident, at the lower threshold speed, regardless of whether the passenger is wearing a seat belt or not.
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.
