Embodiment Construction
[0024] Below in conjunction with accompanying drawing and embodiment the technical solution of the present invention is further described:
[0025] Such as Figure 1 to Figure 6 As shown, the present invention provides the weakening structure of the airbag area on the automobile instrument panel, including the detonation line processed corresponding to the corresponding position of the airbag 10 on the airbag frame 5, and the detonation line includes the left end detonation line 1 and the right end detonation line 2 Set symmetrically with the middle burst line 3, the left end burst line 1 and the right end burst line 2, wherein, the left end burst line 1 and the right end burst line 2 are all broken lines with an included angle α, and the included angle α=170°, Ensure that the airbag frame 5 has a good flipping ability during the blasting process of the airbag 10, the two ends of the middle bursting line 3 are respectively connected to the angle between the left end bursting l...

The invention relates to the technical field of automobile instrument board safety air bags, in particular to an automobile instrument board safety air bag area weakening structure. The automobile instrument board safety air bag area weakening structure comprises an exploding line which is processed at the position, corresponding to the position of a safety air bag, of a safety air bag frame, theexploding line comprises a left end exploding line, a right end exploding line and a middle exploding line, and the left end exploding line and the right end exploding line are symmetrically arranged.The automobile instrument board safety air bag area weakening structure is characterized in that the left end exploding line and the right end exploding line are both broken lines with the included angle alpha which is greater than 160 degrees and smaller than 180 degrees, the two ends of the middle exploding line are correspondingly connected with the inclined-angle positions of the left end exploding line and the right end exploding line, and auxiliary exploding lines which extend oppositely are symmetrically arranged at the two ends of each of the left end exploding line and the right endexploding line. By means of the technical scheme, the automobile instrument board safety air bag area weakening structure has the advantages of being reasonable in structure design, convenient to process and high in safety.
Description
technical field [0001] The invention relates to the technical field of automobile dashboard safety airbags, in particular to a region weakening structure of the automobile dashboard safety airbag. Background technique [0002] With the continuous development of automobile technology, the requirements for the instrument panel, which integrates safety, functionality, comfort and decoration, are getting higher and higher, especially its safety. In terms of safety, the instrument panel can be divided into a non-airbag instrument panel and an airbag-attached instrument panel (for the co-pilot). The airbag system is called the auxiliary occupant protection system. When the car is hit by a collision and the speed of the vehicle changes sharply, the airbag will expand rapidly to buffer the inertial force of the occupants in the car, reduce the degree of human injury, and achieve the effect of protecting the occupants. [0003] The passenger airbag (PAB) is arranged on the co-pilot ...
