Abstract

The invention relates to the technical field of automobile safety belt devices, in particular to a safety belt curling apparatus and a retractor with the safety belt curling apparatus. The safety beltcurling apparatus comprises a main curling spring assembly, a sub-curling spring assembly and a control disc assembly; according to the safety belt curling apparatus and the retractor with the safetybelt curling apparatus, the sub-curling spring assembly does not start when a safety belt is pulled out by arranging the sub-curling spring assembly generating reverse torsion relative to the main curling spring assembly and the control disc assembly controlling the sub-curling spring assembly to generate the reverse torsion on the basis of the main curling spring assembly to guarantee the safetybelt can be normally pulled out; when the belt is pulled out to a certain position and recovers and tightens, the control disc assembly can control the sub-curling spring assembly to generate a portion of torsion to resist tightening of the safety belt, so that force of the safety belt on human bodies is not so big, comfortableness is higher during wearing, and strapping sense does not come intobeing.

Description

technical field

[0001] The invention relates to the technical field of automobile seat belt equipment, in particular to a seat belt curling device and a retractor comprising the seat belt curling device. Background technique

[0002] The curling device of the automobile safety belt retractor is connected with the mandrel assembly, and the coil spring assembly is arranged in the curling device, and the seat belt wound on the mandrel assembly is recovered by the action of the coil spring assembly, so as to ensure that the seat belt is always Stick to the human body. However, the pulling force of the coil spring assembly is relatively large, and wearing the safety belt for a long time will cause the human body to feel restrained and the comfort level is poor. Therefore, how to reduce the restraint feeling of the seat belt under the premise of ensuring safety has become a problem to be solved. Contents of the invention

[0003] The purpose of the present application is to pr...
