Abstract
With the in-depth understanding of vehicle’s safety knowledge and the increase of seatbelt’s wearing rates, people pay more and more attention to seatbelt’s wearing comfort and rapid retraction performance. Also, the Chinese market’s complaint about seatbelt is increasing. From the IQS result, the main part of seatbelt’s IQS complaint in Chinese market is about seatbelt’s retraction performance, and it shows an upward trend. The friction between seatbelt’s through ring and webbing is an important factor that influences the performance of seatbelt’s retraction, but there is no enough research result or selection standard about the friction coefficient of the through ring and webbing. In this paper, we analyzed the layout of seatbelt and the main factors affecting webbing’s retraction, set orthogonal test matrix for the combination of different through rings and webbings, obtained the friction coefficients, and analyzed its influence to the webbing’s pull-out and retract force. This work will provide a lot of convenience for the development of follow-up vehicles.
