Abstract: The invention relates to an airbag apparatus for motor vehicles, in particular to a side airbag apparatus comprising a gas generator and a gas filling tube. The tube is provided along its length at predetermined distances gas overflow openings. The openings are connected to an inflatable gas bag which extends at least over a greater portion of the length of the tube and preferably consists of individual cells. Each cell is associated with a pair of gas outflow openings. The gas outflow openings are formed by incisions in the wall of the gas filling tube and by indentations of the tube wall material on one side of the incisions and extending at an angle to the tube axis.

Abstract: The invention relates to an airbag apparatus comprising a gas generator (11) which has at a periphery a plurality of, preferably two diametrically oppositely lying gas outlet openings (12), a housing (13) which receives the gas flowing out of the gas generator (11) and is mounted at the gas generator in a gas and pressure tight manner, and a gas conduction line (14) leading to an inflatable gas bag. The invention consists in that the housing (13) lies in contact with the outer periphery of the gas generator (11) only at one side and has at least one gas inlet opening (15) lying opposite to a gas outlet opening (12); and in that at least one gas inlet opening (15), which lies diametrically opposite to a gas outlet opening (12), is closed by a closure means (16), in particular a plug, in a gas and pressure tight manner.

Abstract: The invention relates to an airbag apparatus for motor vehicles, in particular to a side airbag apparatus comprising a gas generator (11) and a gas filling tube (12) which is connected thereto, which preferably consists of metal, which preferably is or can be laid respectively along the roof strut of the motor vehicle, which is provided along its length at predetermined distances with individual or pair-wise adjacently arranged gas outflow openings (13) and which is connected to an inflatable gas bag which extends at least over a greater portion of its length and preferably consists of individual cells, each of which is preferably associated with the or a pair of gas outflow openings (13) respectively, with the gas outflow openings (13) being formed by incisions (17) in the wall of the gas filling tube (12) which are preferably made by means of a planar tool such as a saw, and by indentations (18) of the tube wall material on one side of the incisions (17) and extending at an angle to the tube axis (16), with

Abstract: The invention relates to a method of manufacturing an airbag which consists of a plurality of airbag parts and has an airbag envelope. In the method at least one airbag part is provided at least regionally with a polyurethane coating through the heating of which the airbag part can be welded to a further airbag part.

Abstract: Inflatable side airbag with duct-shaped forming chambers (19) having a fastening side (11), which is provided for the fastening of the airbag along a substantially curvilinear fastening section (23) along a roof spar of a motor vehicle, as well as a free side (15) which can be unfolded through inflation of the airbag, which is fastened at the fastening section (23), along a main development direction (A) which extends substantially downwardly in the vertical direction, and which free side in the thus inflated state of the airbag is provided at the lower side of the airbag as well as lying substantially opposite to the fastening side (11), with the cut of the airbag along the fastening side (11) having a substantially rectilinear border, which has substantially the same length as the total length of the curvilinear fastening section (23), and with the cut having a substantially curvilinear border along the free side (15).

Abstract: The invention relates to an airbag apparatus for motor vehicles, in particular to a side airbag apparatus, comprising a gas generator (11), a gas filler tube (12) which is tightly connected thereto, which preferably is or can be laid in along the roof spar of the vehicle, which is provided with gas outflow openings (13) at predetermined distances and which is connected to an inflatable gas bag (14) which extends at least along a greater portion of its length and which preferably consists of individual cells (15), of which each is preferably associated with a gas outflow opening (13). The invention consists in that the gas outflow openings (13) are formed by incisions (17) in the wall of the gas filler tube (12) and by indentations (18) of the tube wall material at least at one side of the incisions (17).
