Abstract: The invention relates to an airbag system comprising an airbag module, which has an opening mechanism for the airbag tear seam of a seat cover for the airbag accommodated underneath the cover in a non-visible manner, wherein the opening mechanism is configured such that the deploying force of the airbag tears a hole or holes into the tear seam, which bring(s) about a slight opening of the seam according to the physics of a ‘run,’ wherein a strip, or plurality of strips, or strip ends sewn into the airbag tear seam of the seat cover in more than one locations is/are torn from the seam driven by the deploying force of the airbag. The invention further relates to a vehicle seat comprising such an airbag system, and to a deployment method for such an airbag system.

Abstract: The invention relates to an air bag system which has multi-stage gas generating devices, with a primary stage for the partial inflating of an air bag and at least one subsequent stage which can be electrically and/or electronically triggered only as a function of an unhindered expansion of the air bag because of the inflating by a preceding stage, at least one electric switch being provided which can be switched as a function of the undisturbed expansion of the air bag because of the inflating by the preceding stage and is connected for the electric and/or electronic triggering of the subsequent stage.

Abstract: The invention relates to an air bag arrangement in vehicle, having a gas bag which, as the result of a triggering by a sensor, can be inflated with gas by a gas generator and, during the inflating, can be advanced into an interior of the vehicle, the gas generator having at least two driving stages with propellant charges which can be ignited in a time-related succession and of which the first propellant charge is ignited by a triggering by a sensor and the second propellant charge being ignited facultatively when the gas bag moves beyond a defined advancing position.

Abstract: The present invention relates to an air bag system having an air bag and a covering which contains at least one tearing thread in an outlet area of the air bag for opening the covering. The tearing thread is a thread of a woven fabric and/or of a seam of the covering in the outlet area of the air bag. Tearing devices are provided which, in the outlet area of the air bag from the covering, are applied to the at least one tearing thread and are coupled to the air bag system. When the air bag system is triggered, the tearing devices weaken or open up the covering before or during inflation of the air bag by severing the at least one tearing thread. Furthermore, the invention relates to an interior vehicle covering which is suitable as a covering of the air bag system, a seat equipped with such a covering and air bag system, and a triggering process of an air bag system situated under a covering.

Abstract: A drive device includes a piston guided linearly in at least one pressure tube. The drive for the piston includes a plurality of pyrotechnic drive cartridges ignitable in succession, and is especially useful for tightening a seat belt in a motor vehicle. The linear movement of the piston, urged as a result of an initial ignition, triggers subsequent ignitions for driving the piston. The drive cartridges are ignited in succession.

Abstract: A motor vehicle seat is disclosed having a backrest on which a headrest is adjustably arranged. In this case, a headrest, which can be adjusted into a protective or safety position, and an energy accumulator are provided which can be activated in the event of a crash and operates a driving device which is designed for adjusting the headrest into the protective or safety position.

Abstract: A side air bag system has at least one inflatable air bag, a supporting strap which can be tensioned in the area of the inflated air bag, as well as operating devices for tensioning the supporting strap and inflating the air bag into their protective positions. The supporting strap is coupled with the air bag such that the tensioning supporting strap pushes the air bag out of its folded position into its protective position. An operating process for a side air bag system has at least one inflatable air bag, a supporting strap which can be tensioned in the area of the inflated air bag and operating devices for inflating the air bag and tensioning the supporting strap into their final protective positions, in which case the unfolding of the air bag from a folded condition into an at least essentially unfolded condition is at least supported by the tensioning of the supporting strap.

Abstract: An inner lining for a motor vehicle with a finished ceiling made of a self-supporting form piece attachable to the edge of the motor vehicle structure includes at least one air-bag which is premounted on the self-supporting form piece before the ceiling is installed in the motor vehicle.

Abstract: The invention relates to an air bag arrangement in a vehicle, having a gas bag device which can be inflated with a propellant by a gas generator 4 as the result of the triggering by a sensor and which, during the inflating, can be advanced into the occupant compartment of the vehicle, a covering device 10 being provided which is driven by a component 5; 5' of the air bag arrangement set in motion after the triggering by a sensor and which opens up an outlet opening 7 for a gas bag 8 and which moves essentially inside an outer contour 15 of the air bag arrangement or of a vehicle part containing the air bag arrangement.
