A method and system for restraining an occupant on a vehicle seat, the occupant being pulled into the vehicle seat is provided with a force by a belt tensioner when a critical driving state is detected and then held in a pulled-back position on the vehicle seat with a holding force. The holding force selected is lower than the force for pulling the occupant back. A forward-looking detection system for a dangerous driving state and an occupant-position detection system unprovided, in which, when a dangerous driving state is detected, a belt tensioner is subjected to a force and the occupant is thereby pulled into the vehicle seat, and in which the occupant is held in a pulled-back position on the vehicle seat with a holding force which is lower than the force for pulling the occupant back.

In a method for triggering a two-stage air bag generator in a motor vehicle, an acceleration signal is measured, processed and evaluated with respect to the accident severity according to a first evaluation process. As a function of the determined accident severity, a triggering decision is made at least for the triggering of a first stage of the gas generator. At least until a defined time period T1 has elapsed since the ignition of the first stage, the acceleration signal is evaluated according to a second evaluation process with respect to the accident severity before, on the basis of defined triggering conditions, as a function of the determined accident severity, a triggering decision is made for igniting the second stage of the gas generator.

In a belt roller for a safety belt system, a rod assembly has a torsion rod as well as at least one torsion sleeve which surrounds it coaxially. A stopping mechanism is provided with at least two axially offset stopping element sections, which can be adjusted either individually or jointly to the at least one torsion sleeve and to the torsion rod through the use of a control mechanism depending on the energy absorption capacity to be applied.

The invention relates to a collision-protection system for passengers of motor vehicles. In a manner which is known in principle, an airbag is automatically inflated in the event of an accident. In order to control the direction and speed of expansion, the airbag is wholly or partially encased by a tough, plastically deformable film, which is overstretched and torn open as the airbag is inflated.

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.

A triggering mechanism for a side airbag has a deformation sensor for determining a rate of deformation. The deformation sensor is made up of a total of two pressure-sensitive sensor elements, which are attached on a firm carrier plate parallel to the outer skin inside the vehicle. Spacer elements support the carrier plate against a structural element running parallel to the outer skin. The pressure-sensitive surface of a first sensor element in this case faces the outer skin and the pressure-sensitive surface of a second sensor element faces the structural element. The spacer elements are designed, for example, using predetermined buckling points, clip elements, etc., in such a manner that they withstand a pressure on the support plate only up to a threshold and, if the threshold is exceeded, yield abruptly. This is so that, in the event of a deformation-induced force effect, the sensor elements respond one after the other. An evaluation circuit checks the time interval between the two sensor signals and, below a critical time, sends a triggering signal to the side airbag.

The invention relates to an occupant restraint system having an air bag which is automatically inflated by means of a gas generator in the event of an accident and, during this process, emerges from a housing or the like whilst opening a padded flap which normally closes the housing or the like. In this case, an intended tearing point arranged at the edge of the flap remote from the pivot axis is undone, which intended tearing point is shielded by a thick pad swelling from contact by the occupant to be protected.

In an impact protection cushion which can be accommodated in the steering wheel region for protection of the vehicle driver, a tearing seam is provided which joins the cushion upper part, which moves forward upon inflation, to the cushion lower part fastened to a fixed vehicle part. This arrangement prevents any radiating forward movement of parts of the cushion upper part, in particular, of a central region laying opposite the gas inflow opening in the cushion lower part without restraining straps.

A motor vehicle is disclosed having a safety belt assigned to a seat and having an airbag system which is assigned to the same seat and has a pressure gas source which can be actuated by means of a deceleration sensor. In order to optimize protection for the seat user in the event of an accident, the invention proposes that at least two pressure gas sources which can be actuated independently of one another are provided, and in that in the event of an accident only one pressure gas source can be actuated by means of the deceleration sensor when the safety belt is being worn, while when the safety belt is not being worn all the pressure gas sources can be actuated so that it is only in this case that the maximum airbag internal pressure is available.

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.

Receptacle arrangement for an air bag

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.

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 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.

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.
