Embodiment Construction

[0034] figure 1 A schematic view of an exemplary embodiment of an airbag module 1 for a motor vehicle (not shown) according to the invention is shown.

[0035] The airbag module 1 has an airbag 2 in a flexible form, a plurality of gas passages 3a, 3b, 3c, and 3d in a flexible form provided on the outside or inside of the airbag 2, and for utilizing gas to the airbag 2 and the gas passages 3a, 3b, 3c and 3d gas generator 4 for charging. The gas passages 3b and 3c are communicatively connected to each other through the passage portion 5, and each of the gas passages 3b and 3c has a branch 6b and 6c, respectively.

[0036] The airbag module 1 also has a pressure chamber 7 in flexible form, which is communicatively connected with at least one gas outlet (not shown) of the gas generator 4, communicatively connected with the gas inlets 2a, 2b and 2c of the airbag 2, And it is communicatively connected with the gas inlets 8a, 8b, 8c and 8d of the gas passages 3a, 3b, 3c and 3d. Th...

Abstract

The invention relates to an airbag module (1) for a motor vehicle, wherein the airbag module has at least one flexibly configured gas bag (2), at least one flexibly configured gas duct (3a, 3b, 3c, 3d) arranged on the outside or the inside of the gas bag (2) and at least one gas generator (4) for inflating the gas bag (2) and the gas channel (3a, 3b, 3c, 3d) with gas. In order to provide the airbag module (1) with the fast inflatable gas bag (2) and an improved structure, the airbag module (1) has at least one flexible pressure chamber (7) which communicates with at least one gas outlet of thegas generator (4), communicates with a gas inlet (2a, 2b, 2c) of the gas bag (2) and communicates with a gas inlet (8a, 8b, 8c, 8d) of the gas channel (3a, 3b, 3c, 3d); the volume of the pressure chamber (7) is smaller is as a volume of the gas bag (2).

Description

technical field [0001] The invention relates to an airbag module for a motor vehicle with at least one airbag in flexible form, with at least one gas channel of flexible form arranged outside or inside the airbag and with At least one gas generator charged with gas. The invention also relates to a motor vehicle having at least one airbag module. Background technique [0002] To protect people, motor vehicles are equipped with airbag modules. If the airbag module has only one airbag connected to the gas generator, the inflation time of the airbag is longer compared to an airbag module in which a gas channel is provided which can also be inflated with gas via the gas generator arranged on the airbag . Furthermore, airbags which are not provided with gas channels generally lack the required dimensional stability in the event of oblique loading. [0003] GB 2 306 214 A discloses a vehicle airbag system in which a sealed pressurized gas cylinder is connected to a chamber via ...
