Preferably, after the airbag 3 is inflated and the first cover 1 moves upwards, the end of the support platform 91 far away from the first cover 1 is still located in the support groove 92. When 3 isolator of gasbag received huge impact, supporting bench 91 can the first apron 1 of effectual reduction transversely rock, simultaneously, when 3 damages of gasbag, supporting bench 91 falls into and also can play the effect of supplementary emergent support in supporting groove 92, and when supporting component can not support a first apron 1 and second apron 2, supporting bench 91's tip and the bottom laminating of supporting groove 92 formed the second and supported first apron 1.
Optionally, as shown in fig. 3, a cushion 93 is provided on the surface of the support table 91 and/or the support groove 92. The cushion 93 may be a spring or rubber or polyurethane.
Example 2:
in this embodiment, as shown in fig. 2 and 5, a plurality of cushion blocks 10 are further disposed between the first cover plate 1 and the second cover plate 2, and the plurality of cushion blocks 10 are distributed outside the airbag 3. One end of the cushion block 10 is connected with the first cover plate 1 or the second cover plate 2 through a fixing bolt 11. Of course, the spacer 10 may be fixed to either the first cover plate 1 or the second cover plate 2 by bonding.
The cushion block 10 is a cushion block 10 made of polyurethane or plastic or rubber with certain elasticity, preferably a polyurethane cushion block. When the air bag is not inflated, the other end of the cushion block 10 is attached to the other of the first cover plate 1 or the second cover plate 2 to form an auxiliary supporting function. When the gasbag takes place the damage after aerifing, cushion 10 also can play the effect of supplementary emergent support to, cushion 10 self elasticity ability that has can form the buffering to the first apron 1 that falls.
In the present embodiment, as shown in fig. 2, the number of the spacers 10 is two. When the number of the supporting components is two, the two cushion blocks 10 and the two supporting components can stably support the first cover plate 1 and the second cover plate 2 together. Of course, the number of the cushion blocks 10 can be adjusted according to actual needs, and is not limited to two.
The rest of the structure of this embodiment is the same as embodiment 1.
