[0039] The seat belt retractor in the vehicle may have an emergency locking function. When the vehicle is in emergency braking, head-on collision or vehicle rollover, the seat belt retractor can instantly lock the seat belt to fix the occupant in the seat to prevent the occupant from falling out of the vehicle or colliding. To this end, the seat belt retractor mounting assembly used to fix the seat belt retractor must have sufficient strength and stability to ensure the reliability of the connection between the seat belt retractor and the vehicle.

[0040] An embodiment of the present application provides a rear seat belt retractor mounting assembly, which can be used to fix the rear seat belt retractor, and the rear seat belt retractor mounting assembly can be fixed inside the vehicle, so that the rear seat belt retractor can be fixed to the vehicle through the rear seat belt retractor mounting assembly.
