Abstract: The invention relates to a gas bag module for a vehicle occupant restraint system, in particular a side gas bag module extending along a roof frame of the vehicle. The gas bag module comprises a gas bag and a housing with two separate side pieces which define an ejection channel for the gas bag. One of the side pieces is to be located close to the frame and the other of the side pieces is to be located close to an interior of the vehicle. The side pieces each have upper and lower ends constituting marginal sections. The side piece close to the interior is constructed to be so elastic and to have such a shape adapted to a shape of the side piece close to the frame, that the side piece close to the interior only rests against an outside of side piece close to the frame and embraces the latter in the manner of a clip.

Abstract: An assembly consisting of a cylindrical inflator, a housing and a retainer by means of which the inflator can be fixed in the housing. The inflator has a longitudinal centerline and a circumferential surface area and the retainer comprises a circular opening with an edge. Protruding from the edge into the opening are tabs which engage the circumferential surface area of the inflator to fix the latter in the opening.

Abstract: A belt spool for a belt retractor comprises a torsion rod and a spool body that has a recess in which is provided a shaped part by means of which an end of a safety belt can be fastened in the recess. The shaped part rests at the torsion rod in order to be supported when the shaped part is stressed by a tensile load of the safety belt. There is also proposed a belt retractor including such a belt spool.

Abstract: An assembly consists of a car body, a windshield, a dashboard with an air vent for providing an air flow to the windshield, and an airbag module. The airbag module is arranged between the windshield and the air vent.

Abstract: An actuating device for a safety arrangement in a vehicle has a pneumatic muscle as drive and a pyrotechnical gas generator for feeding the pneumatic muscle.

Abstract: In a folded gas bag for a vehicle occupant restraint system the folded gas bag comprises two superimposed walls of the gas bag laid in folds and the folded gas bag is delimited by imaginary first and second fold edge regions. The fold edges of the folds extend in a straight line and parallel to one another. The folds have fold heights measured from one of the fold edge regions and at least two differing fold heights are provided.

Abstract: A gas bag for a vehicle occupant restraint system includes a wall, an inflation port configured therein, a deflection part arranged between the inflation port and a portion of the gas bag wall arranged opposite the inflation port, and a counterpiece which is arranged between the deflection part on the one hand and the inflation port as well as a portion of the gas bag wall surrounding the inflation port on the other hand. The deflection part and the counterpiece are stitched to each other such that a prechamber is formed which communicates with the interior of the gas bag by overflow ports formed between the deflection part and the counterpiece.

Abstract: The invention relates to a vehicle occupant restraint system, comprising a side gas bag module which contains a gas bag folded into an elongated packet and having inner and outer sides when unfolded. The gas bag packet has an underside and a side face adjoining thereto and is surrounded by a flexible protective covering which has a predetermined tear line along the side face, so that the protective covering, on an unfolding of the gas bag, opens in a region of the side face of the gas bag packet and two sections of the protective covering, which are of differing length, extend along the inner and outer sides of the unfolded gas bag.

Abstract: A headrest in a vehicle seat includes an inflatable protective cushion in which the contact surface area is increased and caused to approach the head without needing to provide burst seams in the upholstery or in the cover or to make use of an elastic covering material. The protective cushion is arranged between the headrest frame member and the upholstery. The cover or the upholstery is joined at its outer circumference by jointing means to the headrest frame member. The jointing means maintain the cover, or the upholstery, tensioned in the non-activated condition of the protective cushion and permit a limited displacement of the outer circumference of the cover, or upholstery, from the headrest frame member in the activated condition of the protective cushion. The upholstery may thus be brought by the protective cushion nearer to the head and the contact surface area may be enlarged without destroying the cover or upholstery.

Abstract: An inflatable side gas bag for a vehicle occupant restraint system comprises an upper edge by means of which it can be fastened in a vehicle. The side gas bag has an upper portion adjacent the upper edge and a lower portion remote from the upper edge. In a non-inflated condition, the upper portion of the side gas bag is folded in another way as the lower portion. There is proposed a method of folding such a side gas bag, and a side gas bag module incorporating such side gas bag.

Abstract: An inflatable side impact airbag for a vehicle occupant protection device comprises an upper edge to attach it in the area of an A-column and of a roof frame of a motor vehicle. The upper edge of the airbag is straight. Further, there is proposed a method of installing such an airbag.

Abstract: A gas bag module for a vehicle occupant restraint system includes a gas bag having at least a first fabric layer which is made of interwoven weft threads and warp threads and which forms a wall of the gas bag. The gas bag module also includes a gas lance with openings for an inflow of a gas into the gas bag. A second fabric layer is disposed in the area of the openings and is formed by part of the weft threads of the first fabric layer.

Abstract: An airbag module for a vehicle occupant restraint system comprises a gas generator, an airbag which can be inflated by means of a pressurized gas flow that can be supplied by the gas generator. The airbag module further comprises a housing that has a generator chamber to accommodate the gas generator and an airbag chamber to accommodate the airbag. A deformable dividing wall is provided between the generator chamber and the airbag chamber, the dividing wall having outlet openings and being adapted to be deformed by the pressurized gas flow from a resting state into a working state in which the dividing wall forms a guide channel for the pressurized gas flow flowing out of the gas generator.
