[0006] As a further scheme of the utility model, the upper main piece is perpendicular to the support air bag in the direction of unfolding, and the top has a larger area.

[0007] As a further scheme of the utility model, the support air bag is equipped with a slope on both sides, so that the support air bag forms a special-shaped structure suitable for the space between the door and the seat.

[0008] As a further scheme of the utility model, one side of the generator is equipped with a wire harness for energizing the generator.

[0009] As a further scheme of the utility model, the support air bag is fixedly connected with a support inside, and the generator is detachably connected to one side of the support through bolts.

[0010] The utility model has the following technical effects and advantages:

[0011] 1. The utility model forms a support airbag by providing a lower main piece and an upper main piece. During the deployment of the airbag, the top of the airbag contacts the person's arm in a vertical state, which can effectively lift the person's arm and ensure that during a collision, there is only the inflated airbag as a buffer structure between the person's torso and the car door, thereby achieving the effect of protecting the torso.

[0012] 2. The utility model has an upper main plate that is perpendicular to the deployment direction of the airbag and has a larger top area, which can effectively support the arm and lift the arm to avoid hard contact between the car door and the person, thereby achieving a protective effect.
