Embodiment Construction

[0024] Below, according to Fig. 1 to Fig. 7, a preferred embodiment of the present invention is given and described in detail, so that the functions and characteristics of the present invention can be better understood.

[0025] The invention provides a head collision energy-absorbing device, which can control the energy-absorbing structure by rationally designing the energy-absorbing structure bracket and adjusting the position and number of openings on the bracket in the limited space behind the passenger side airbag cover of the instrument panel. can effect.

[0026] Fig. 1 is a three-dimensional structure diagram of the head impact energy absorbing device and the airbag module of the present invention. As shown in the figure, the head impact energy-absorbing device is a combined bracket 2 fixedly connected to the instrument panel body (not shown). The airbag module 1 is rigidly fixed to a cross member of the instrument panel (not shown).

[0027] The gist of the design o...

Abstract

The head collision energy absorbing set connected to the switch board of automobile is one frame structure including one hollow cavity to hold the air bag assembly. In case of collision between the head and the switch board, head collides first with the switch board and the switch board deforms to absorb energy; the switch board collides then with the combined support and the combined support and the switch board shift downwards integrally. When the combined support collides with the air bag assembly, the combined support deforms greatly to absorb most of the energy, lower the head acceleration and reduce collision damage.

Description

technical field [0001] The invention relates to a head collision energy-absorbing device, in particular to a head collision energy-absorbing device installed behind an airbag cover plate on the passenger side of an automobile instrument panel with limited internal energy-absorbing space. Background technique [0002] With the rapid development of the automobile industry, consumers have higher and higher requirements for automobile safety, and the automobile industry is also paying more and more attention to safety, especially for the protection of drivers and passengers. Many ingenious and efficient energy-absorbing structures are widely used. [0003] As mentioned above, an airbag is usually arranged on the passenger side of the car dashboard. The airbag is provided with an independent airbag cover on the instrument panel, which is normally closed. The FMVSS201 regulation requires that the entire instrument panel must pass the head impact test. It is required that when th...
