In this way, the cooperation of the first locking member 31 and the second locking member 32 can realize the locking and unlocking of the locking device 3. Moreover, the first locking member 31 and the second locking member 32 are respectively connected to the guide plate 1 and the trim panel 4, so that the locking device 3 is integrally arranged on the trim panel 4, and the structure is compact and occupies a small space. In addition, the first locking member 31 is located on the side of the guide plate 1 away from the air curtain pull belt 5, and does not interfere with the escape of the air curtain pull belt 5 from the trim panel 4.

[0039] Optionally, one of the first locking member 31 and the second locking member 32 is a permanent magnet or an electromagnet; the other of the first locking member 31 and the second locking member 32 is an electromagnet; the first locking member 31 and the second locking member 32 are configured to be magnetically attracted to each other when the air curtain is not unfolded, and the magnetic attraction is released when the air curtain is unfolded.

[0040] In one embodiment, the first locking member 31 is a permanent magnet, and the second locking member 32 is an electromagnet. When the electromagnet is powered, the first locking member 31 and the second locking member 32 are attracted to each other to achieve locking; when the air curtain is deployed, the electromagnet is powered off, and the permanent magnet is no longer attracted, to achieve unlocking.
