Abstract

The invention discloses a gas distributing device of an automobile safety airbag, which is arranged in the airbag and is provided with a fixed part fixed on the airbag and a gas guiding part arranged in the airbag, wherein the distributing device is a bucket-shaped body; a gas outlet of a gas generating device for inflating the airbag is positioned in the distributing device; the fixed part as a part of the wall of the bucket-shaped body of the distributing device and the airbag are fixed to two end parts of the distributing device in the axial direction; and the gas guiding part as the other part of the wall of the bucket-shaped body of the distributing device and the fixed part are opposite along the axial direction of the distributing device. The airbag has a simple structure and convenience of processing, and the whole airbag is firm in operation, can bear gas impact of higher temperature and pressure, and ensures realization of the gas distributing process.

Description

technical field [0001] The present invention relates to a component of an automobile safety air bag, in particular to a diverter 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 vehicle or the outside world. 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 inlet, its edge part is fixed on the airbag by sewing thread, and there is a gap between the other p...
