Embodiment Construction

[0024] figure 1 Shown is the working schematic diagram of gas splitting device 2 of the present invention in automobile safety air bag 1, figure 2 for figure 1 A schematic diagram of the gas splitting device of the present invention. Such as figure 1 and 2 As shown, the gas distribution device 2 according to the present invention is built in the automobile airbag 1, and has a fixed part 21 fixed on the airbag 1 and a gas guide part 22 placed in the airbag 1, wherein: the The gas distribution device 2 is a cylindrical body. Preferably, the gas outlet of the gas generating device (not shown) for inflating the airbag 1 is located inside the gas distribution device 2, so that the gas emitted from the gas outlet will pass through the gas distribution device 2 and be passed through the gas distribution device 2. The gas guiding part 22 of the gas splitting device 2 guides the split flow into the airbag. Meanwhile, the fixing portion 21 , which is a part of the cylindrical sha...

Abstract

Disclosed is a gas diffusing device (2) disposed inside a motor vehicle safety airbag, wherein the airbag (1) is inflated by a gas generator via the gas diffusing device (2), the gas diffusing device (2) has a fixed part (21) fastened on the airbag (1) and gas guiding part (22) disposed in the airbag (1). The gas diffusing device (2) is a cylindrical body; the fixed part (21), being one part of the cylindrical body of the diffusing device (2), is fastened by sewing to the airbag (1) by at least one thread (4), and the gas guiding part(22), being the other part of the cylindrical body, is a continuous face with no thread provided, such that the gas from the gas generator enters the airbag (1) along the gas guiding part (22) so as to inflate the airbag (1). The gas diffusing device (2) can sustain relatively high pressure without being damaged. In addition the diffusing device (2) can better handle the regulation of an inflation process for an airbag with multiple chambers. Furthermore the diffusing device (2) also has the feature of being able to be rapidly and firmly fastened to the airbag and the gas generator.

Description

technical field [0001] The invention relates to a component of an automobile safety air bag, in particular to a gas distribution device for guiding gas from a gas generating device into the air bag. Background technique [0002] As a safety protection device for a vehicle, the airbag is supplied with gas by a gas generating device and inflated to form a cushioned soft protection between the occupant and the outside world (such as the vehicle). In order to control the direction of the gas entering the airbag so as to obtain a better shape of the airbag during inflation and provide controllable protection, a gas splitter is used to achieve the above purpose. [0003] For example, in the known US Pat. No. 5,573,270A, an X or Y type flow splitting device is used at the inlet of the airbag to achieve the above object. The device is a piece of fabric with a large area covering the airbag air inlet, its edge part is fixed on the airbag by sewing thread, and there is a gap between ...
