TUBULAR GUIDE FOR CONTROL CABLES OF WINDOW REGULATORS FOR AUTOMOTIVE VEHICLES

摘要

The tubular guide (10) for slidingly receiving the control cable of a window regulator for automotive vehicles includes at least two superimposed layers (11, 12). The inner layer (12) is formed of an acetal resin having high hardness, rigidity and wear resistance and a small friction coefficient intended to prevent the groove formation in the inner surface and to offer a smallest resistance to the control cable sliding movement. The outer layer (11) is formed of an acetal resin containing elastomers for increasing the resistance of the tubular guide to the mechanical stresses.
