Abstract
The embodiments described and claimed herein relate to opening in a housing for a retractor. The opening includes structures which reduce the risk of twisting webbing passing through the opening and, thereby, interfering with the proper functionality of the retractor. The openings can include one or more guide surfaces which incorporate some combination of features which smooth out the webbing as it enters the retractor and/or urge the webbing into alignment with the retractor opening. In addition, or in the alternative, the height of the opening can be modified to closely conform to the maximum thickness of the webbing. The guide surfaces can be integrally formed with the retractor housing or can be provided by an insert piece which attaches to the housing. In one embodiment, the guide surface is disposed along an upper wall of the opening and is curvilinear and outwardly diverging. More specifically, the guide surface has slopes that vary along its length whereby the guide surface is approximately vertical near a leading edge of the guide surface and is approximately horizontal near a trailing edge of the guide surface.
