Problems solved by technology

Because the inflation method is uncontrollable, the airbag usually unfolds at a certain position first, and then spreads to the surroundings. The speed of inflation leads to uneven pressure of the airbag, which makes the stiffness of each position of the airbag different, but it cannot meet the requirements for the stiffness of the airbag. Good for occupant protection

Embodiment Construction

[0017] In order to further explain the technical means and effects adopted by the present invention to achieve the intended invention purpose, the specific implementation, structure, features and effects of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0018] figure 1 It is a schematic structural diagram of a side airbag in an embodiment of the present invention. figure 2 yes figure 1 Schematic from another angle. Please refer to figure 1 and figure 2 , The side airbag of the present invention is arranged on the side of the car seat, and includes a gas generator 10 , a first airbag 20 and a second airbag 30 .

[0019] The first air bag 20 is connected to the gas generator 10 through a circular hole (not shown) on the gas generator 10 . The volume of the second air bag 30 is much larger than that of the first air bag 20, and it is surrounded by the periphery of the first air bag 20, that...

Abstract

The invention discloses a side air sag, which comprises a gas generator, a first air bag and a second air bag, wherein the first air bag is connected with the air generator; a plurality of through holes are uniformly distributed in the first air bag; and the first air bag and the second air bag are communicated with each other through the through holes. According to the side air sag, the through holes are uniformly distributed in the first air bag, so that the upper, middle and lower inflating speeds are equal in the inflating process of the second air bag, the inflating pressure is uniform, the rigidity of each part is uniform after inflation of the second air bag, and requirements of passengers on the rigidity of different positions of the air sag are met.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a side air bag of an automobile. Background technique [0002] As an occupant protection device, side airbags are widely used in major OEMs. In order to improve the protective effect of side airbags, it is generally hoped that the local stiffness of the airbag corresponding to each part of the occupant is relatively uniform, and the corresponding stiffness of the hip is relatively large, so as to improve the hip. The propulsion effect reduces the occupant's injury, and at the same time, the corresponding rigidity of the chest is required to be relatively small to reduce the impact of the airbag on the chest. [0003] The current side airbag is mainly composed of a gas generator and an airbag, and the amount of inflation directly affects the stiffness of the airbag. Because the inflation method is uncontrollable, the airbag usually unfolds at a certain position first, and then spreads ...
