For a three-row vehicle, the air curtain bracket device 100 can be mounted on either the C-pillar or the D-pillar.

[0027] The air curtain bracket device 100 includes a Figure 2 ) is mounted to a first fixing structure 10 away from the A-pillar of the vehicle body and a vehicle body fastening unit 20 that fixes the first fixing structure 10 to the vehicle body.

[0028] like Figure 1 and Figure 3 As shown, the first fixing structure 10 includes a first mounting plate body 11 .

[0029] The first mounting plate body 11 is provided with a first mounting hole 12 that cooperates with the vehicle body fastening unit.

[0030] The upper end of the first mounting plate body 11 is provided with a pre-hanging arm 13 that extends into the fixing hole of the vehicle body. The pre-hanging arm 13 and the first mounting plate body 11 are designed as a whole. In some embodiments, the number of pre-hanging arms 13 can be adjusted as needed, and there is at least one. Figure 3 In the embodiment, there are two pre-hanging arms 13 . The pre-hanging arms 13 are symmetrically arranged on both sides of the first mounting hole 12 .

[0031] A through hole 14 is further provided below the first mounting hole. The through hole 14 allows at least a portion of the airbag fixing member 31 of the airbag module to pass through.

[0032] One end of the airbag fixing member 31 is connected to the air curtain, and the other end is connected to the pre-hanging arm 13 and the vehicle body fastening unit 20. The airbag fixing member 31 can be a drawstring or a hook extending from the airbag module 30. The drawstring or hook is a flexible sheet made of cloth.
