The invention relates to an emergency locking
retractor for
noise reduction on a vehicle sensing
assembly. The emergency locking
retractor comprises a belt sensing
assembly, a
noise reduction piece and the vehicle sensing
assembly; the belt sensing assembly is provided with a disc outer tooth, the
noise reduction piece is arranged on the disc outer tooth, the interaction force exists and the
extrusion is generated between the
noise reduction piece and the disc outer tooth, and the disc outer tooth performs
circular motion under the trigger of a ribbon and provides a movement trend for the
noise reduction piece to generate
friction force; when the ribbon is unreeled, the
noise reduction piece rotates and squeezes a vehicle sensing arm of the vehicle sensing assembly from the front face or side face through a
locking mechanism of the noise reduction piece, thereby limiting moving space of a
steel ball of the vehicle sensing assembly; when the ribbon is pulled out, the noise reduction piece rotates reversely, and the noise reduction piece breaks away from the vehicle sensing arm of the vehicle sensing assembly. The emergency locking
retractor for the noise reduction at the vehicle sensing assembly has the advantages that the
steel ball state of the vehicle sensing assembly can be limited, so that after a passenger does not wear or wears a safety belt, the
steel ball is in a specified position and cannot move due to vehicle running, thereby eliminating the sound made by the vehicle sensing assembly.
