Problems solved by technology

An obvious defect of this technology is that the mechanism is complicated, and a rope advance and retreat device and an attitude control device are required to ensure that the reference line of the inertial body seat in the car sensor system is always in a vertical position; moreover, if the seat back angle changes greatly , a small impact will activate the seat belt locking device, that is, a slight vehicle vibration and braking will lock the seat belt

Abstract

The application provides a device for rolling up a safety belt. The device comprises a rolling-up device frame, a reel and a vehicle sensing assembly, wherein the vehicle sensing assembly is used to detect a vehicle acceleration; a sway arm is disposed between the vehicle sensing assembly and the reel, and the sway arm can lock and recover rotation of the reel; the device for rolling up the safety belt also comprises a control cam which can limit motion of the sway arm; the device for rolling up the safety belt also comprises a clamping claw and a sway toothed plate, and the sway toothed plate can be rotated relative to a sensor fixation base of the vehicle sensing assembly; one end of the clamping claw can be rotated under driving of the reel and can be slid relative to the reel when the clamping claw is blocked; and the other end of the clamping claw can be meshed with the sway toothed plate. The device for rolling up the safety belt provided by the application comprises the control cam, so the safety belt can be prevented from being locked when locking is not needed.

Description

technical field [0001] The present application relates to the field of vehicle safety, in particular to a safety belt retracting device. Background technique [0002] The seat belt device mounted on the vehicle binds the driver and passengers through the seat belt pulled out from the retractor. When the vehicle collides, the driver and passengers can be restrained on the seat to avoid or reduce the collision accident. injury to persons. In order to ensure that the seat belt can be automatically locked when a collision accident occurs, a vehicle sensing system, namely an acceleration sensor, is installed in the seat belt retractor to detect the deceleration of the vehicle. When the deceleration of the vehicle is greater than the set threshold , the seat belt locking device is activated, so the seat belt cannot be withdrawn from the retractor. Most of the existing mechanical safety belt locking devices use inertial bodies to detect the deceleration of the vehicle. [0003] ...
