FUNCTIONAL ANALYSIS OF THE WEBBING USED IN AUTO SEATBELTS

Abstract

The reason this paper was made was to identify the functions with the highest importance factor of webbing used in auto seatbelts. For these functions to satisfy all the requirements of operating, functions resulted from analyzing the properties of the webbing. Depending on the importance of each function was developed an objective hierarchy of them, pursuing the imposed decisions technic. Using the Analysis and engineering value it was possible to do the functional analysis of the properties of webbing. By setting the functions value it was possible to obtain a series of decisions, specifying that a function corresponds to a single operating property. Following this analysis it was observed that the main characteristic of webbings is that they have a very good resistance to tensile stresses, characteristic imposed by the manner of operation during use. An important factor that was taken into account in analyzing the webbings was the fabric structure. The structure has a major impact on the function and use of webbings in the belt assembly, considering the fact that their primary role is to save the life of the user, in case of impact of a vehicle. Based on this study the following research is focused on the functional properties of the seatbelt, in order to design and manufacture seatbelts with appropriate exploitation properties.
