Abstract

The invention discloses an automobile safety belt retractor with an anti-locking device. The retractor comprises a retractor body and a vehicle sensing anti-locking device; the retractor body comprises a fixing shell, a spindle, a locking assembly and a vehicle sensing assembly; the vehicle sensing assembly comprises a vehicle sensing arm, vehicle sensing ratchets are arranged on the vehicle sensing arm, outer ratchets are arranged on the locking assembly, and the vehicle sensing ratchets are matched with the outer ratchets; the vehicle sensing anti-locking device comprises a vehicle sensing driving gear, a vehicle sensing driven gear and a vehicle sensing locking gear; a vehicle sensing arc protrusion is arranged on the vehicle sensing locking gear, a vehicle anti-locking gap is formed inthe fixing shell; when the vehicle sensing arc protrusion coincides with the vehicle sensing anti-locking gap, the vehicle sensing arm is lifted, the vehicle sensing arc protrusion makes contact withthe vehicle sensing ratchets, and gaps are formed between the vehicle sensing ratchets and the outer ratchets. According to the automobile safety belt retractor with the anti-locking device, the phenomenon that the locking function of the safety belt is triggered by mistake under the normal using state, meanwhile, the locking function cannot normally enabled when an accident happens, and the safety of passengers is ensured.

Description

technical field [0001] The invention relates to the technical field of automobile safety belts, in particular to an automobile safety belt retractor provided with an anti-lock device. Background technique [0002] The locking function on the car seat belt retractor can ensure that the seat belt will not be pulled out when the vehicle encounters an accident, thereby protecting the occupants. However, in many cases the locking function is falsely triggered, causing the seat belt to also be locked during normal use, preventing the seat belt from being pulled out. If the vehicle is on a slope, the locking function of the seat belt will be triggered, causing the occupant to use the seat belt without pulling out the seat belt after getting on the car on the slope; the seat belt retractor of the rear seat is installed on the backrest. After the seat is tilted to a certain angle, the locking function of the seat belt will be triggered, causing the occupant to use without pulling ou...
