The apron bottom 112 is spaced apart from the connecting portion 12 in the first direction. The guide bracket 3 has a guide surface 31, the guide surface 31 and the side body inner panel 2 form a receiving groove 5 having an opening 51, or the guide surface 31 includes a receiving groove 5 having an opening 51, the opening 51 is opened toward a side away from the connecting portion 12 in a first direction (for example, up-down direction shown in fig. 1), the opening 51 is located between the connecting portion 12 and the shield bottom 112 in the first direction, the opening 51 is opposed to the shield bottom 112 in the first direction, and the air curtain body 200 is provided in the receiving groove 5. In other words, the guide bracket 3 is provided between the air curtain body 200 and the connecting portion 12.

In the side curtain air subsystem 1000 of the vehicle according to the embodiment of the utility model, the guide bracket 3 and the side inner panel 2 form the accommodating groove 5 with the opening 51, or the guide surface 31 includes the accommodating groove 5 with the opening 51, and the opening 51 is opened along the first direction (for example, the up-down direction shown in fig. 1) toward the side far away from the connecting portion 12, so that the problem that the connecting portion 12 and the a-pillar protection plate 1 are damaged due to the fact that the part of the curtain air body 200 is unfolded toward the direction near the connecting portion 12 during the unfolding process of the curtain air body 200 can be avoided. Further, the impact of the air curtain body 200 to the connecting portion 12 and the a-pillar guard 1 near the connecting portion 12 at the time of deployment is reduced, and the problem of secondary injury to passengers due to broken fragments of the a-pillar guard 1 caused by the impact is also prevented. Therefore, the bicycle has the advantages of high riding safety and long service life.

Therefore, the side curtain air subsystem 1000 of the vehicle of the embodiment of the utility model has the advantages of high safety and long service life.

Specifically, for example, as shown in fig. 1, the opening direction of the accommodating groove 5 is downward, and the guide bracket 3 is provided between the connecting portion 12 and the air curtain body 200 in the up-down direction in conformity with the direction in which the air curtain body 200 needs to be deployed when protected, and the length of the side body inner panel 2 extends in the front-rear direction of the vehicle.
