Problems solved by technology

Traditional airbags are generally inflated first, and then inflated and deployed after the airbag rushes out. Due to the high inflation speed of the airbag, the huge forward impact force generated when the airbag starts to inflate is likely to cause harm to the human body, especially in people- When the airbag is in close range, it is easy to cause injury to the chest of the driver and occupant who is very close to the airbag and in the direction of its inflation

Embodiment Construction

[0025] like Figure 1-8 As shown, the tubular composite airbag of the present invention comprises a truss 1 connected by a hollow trachea and a buffer airbag 5 arranged above the truss 1, and one or more than one inflation ports 2 are arranged at the bottom of the truss. An air pressure diaphragm 3 is provided at the junction of each layer of longitudinal air pipes and transverse air pipes of the truss, which can withstand different degrees of gas pressure and control the inflation direction of the truss 1 . The top of the truss 1 is provided with an air outlet 4 that communicates with the buffer airbag 5. In the trachea on the top of the truss 1, an air pressure diaphragm 8 is provided at the interface with the air outlet 4. The inflation gas breaks through the air pressure diaphragm 8 and passes through the air outlet 4 to buffer The air bag 5 is inflated to jointly form a high-low pressure composite air bag. A fixed disk 6 is arranged between the truss 1 and the buffer air...

Abstract

A composite tubular airbag can be more quickly aerated by less air while impact forces to passengers are reduced. It has a trussed structure and an auxiliary bag above the former and connected with each other, and can be equipped with more inlets. Pressure membranes are arranged on the connection points between longitudinal and lateral tubes of each storey.

Description

Technical field: [0001] The invention relates to a safety protection device, in particular to a structural improvement of an airbag used for the protection of vehicle drivers and passengers. Background technique: [0002] At present, the airbag system has been used more and more as a restraint device for protecting the heads of drivers and occupants in vehicles. The current safety airbags all use airbags to inflate to form a soft air cushion to play the role of cushioning and absorbing energy, so as to reduce injuries to drivers and passengers. In the event of a collision accident, when it is necessary to activate the airbag, a large amount of gas is generated by the gas generator to inflate the airbag so that it expands into a soft protective layer to cushion the impact of the collision on the human body. When the airbag system is working, the gas generated in the gas generator fills the airbag rapidly. Since this is an instantaneous inflation process, the way the airbag ...
