Problems solved by technology

However, at present, the device for locking the ratchet only uses a single pawl. When an emergency occurs in the car, it is often prone to great acceleration and great impact, and the locking force of a single pawl is limited, resulting in The locking ability of the seat belt retractor is difficult to meet the ideal requirements

Abstract

The invention provides a seat belt retractor. The seat belt retractor comprises a mounting plate I, a mounting plate II, a ratchet wheel, a scroll, a safety belt, torsion springs, a pawl I, a pawl II and a safety belt clamping device, wherein the ratchet wheel is fixedly connected with the scroll; the ratchet wheel and the scroll are mounted between the mounting plate I and the mounting plate II; the safety belt is wound on the scroll; two ends of the scroll are provided with the torsion springs; between the mounting plate I and the mounting plate II, the pawl I, the pawl II and the safety belt clamping device are arranged in a position corresponding to the ratchet wheel; and moreover, in case of emergency braking of an automobile, the pawl I and the pawl II cooperate with each other to mutually lock the rotation of the ratchet wheel; meanwhile, the safety belt clamping device clamps the safety belt. According to the invention, as the pawl I and the pawl II cooperate with each other to mutually lock the ratchet wheel and the safety belt is clamped at the same time, the locking capacity of the seat belt retractor is improved from different perspectives and the safety and reliability of the automobile during running are also improved.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to a safety belt retractor with double locking functions, which belongs to the technical field of automobile parts. Background technique [0002] Seat belts are one of the most important passive safety measures for automobiles. In view of their remarkable protective effects, 29 countries and regions around the world have formulated regulations on the equipment and use of seat belts. The functional requirement for the retractor is to roll up the webbing for protection when the seat belt is not in use. In use, the retractor must not hinder the free retraction of the webbing when the wearer is doing normal activities. The locking webbing restrains the occupant on the seat when there is a large acceleration or the vehicle body tilts beyond a certain level. Therefore, how to improve the locking capability and locking reliability of the seat belt plays an extremely important ro...
