Detailed Description
To better illustrate the objects, aspects and advantages of the present invention, the present invention will be further described with reference to specific embodiments. This invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concept of the invention to those skilled in the art, and the present invention will only be defined by the appended claims.
As shown in fig. 1-7, a car copilot air bag blasting reduction structure, reduction structure is the rectangle, sets up on the instrument board body, its characterized in that: the airbag comprises a hinge side weakening line 1, an airbag opening side weakening line 2 and two protection side weakening lines 3, wherein the hinge side weakening line 1 and the airbag opening side weakening line are arranged oppositely, the strength of the hinge side weakening line 1 is higher than that of the protection side weakening line 3, and the strength of the protection side weakening line 3 is higher than that of the airbag opening side weakening line 2.
Because the blasting dynamics of air bag is stronger, in order to prevent that the hinge fracture when air bag expandes, protection side weakening line 3 design intensity of both sides will be great than gasbag opening side weakening line 2 intensity, and its effect lies in the protection hinge.
The hinge side weakening line 1 is stressed greatly, the design strength is higher than that of the airbag opening side weakening line 2 and the protection side weakening lines 3 on the two sides, and the hinge side weakening line 1 can be broken.
In order to ensure that the airbag can be normally deployed, the strength of the airbag opening side weakened line 2 needs to be designed to be weakest.
