Abstract

The invention discloses an automobile safety belt retractor provided with an anti-lock device, which comprises a retractor body and a vehicle-sensing anti-lock device; the retractor body comprises a fixed housing, a mandrel, a locking component and a vehicle-sensing component The car sensor component includes a car sensor arm, a car sensor ratchet is provided on the car sensor arm, and an external ratchet is provided on the locking component, and the car sensor ratchet is adapted to the external ratchet; the car sensor anti-lock device includes a car sensor active Gear, car sense driven gear and car sense lock gear; car sense arc-shaped protrusion is arranged on the car sense lock gear, and car sense anti-lock notch is arranged on the fixed shell; when the car sense arc-shaped protrusion and the car sense When the sense anti-lock notch overlaps, the sense arm is lifted, and the arc-shaped protrusion of the sense is in contact with the sense ratchet, and there is a gap between the sense ratchet and the outer ratchet. The invention provides an automobile safety belt retractor equipped with an anti-lock device, which can avoid false triggering of the locking function of the seat belt under normal use conditions, and at the same time, the locking function can be opened normally under unexpected circumstances, ensuring that the occupants Safety.

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...
