  • Patent number: 4993772
    Abstract: A spring-loaded hinge assembly is adapted for use in pivotally interconnected components, such as hinged or pivotal components in accessory assemblies in vehicle applications. The hinge assembly provides for at least a pair of predetermined relative rotational orientations, or detented positions, of the pivotally interconnected components. Each of these detented positions is independently controlled by separate and distinct spring-and-cam arrangements, such that the rotational efforts, and consequently the detent holding forces, can be different from one another, if desired in a given application. The hinge assembly is especially advantageous in covered vanity assemblies on automotive sunvisors, for example.

  • Patent number: 4711483
    Abstract: This invention relates to an improved sun visor assembly particularly adapted for motor vehicle applications. The sun visor assembly includes a mirror which is movable between a stowed position where it is enclosed by the visor, to a withdrawn position where it remains attached to the visor and can be used by the individual seated in the associated seat. The mirror is further completely removable from the visor in accordance with this invention so that it can be used as a hand-held mirror and can be used by other motor vehicle occupants. The visor is provided with a detent mechanism which retains the mirror in the desired stowed or withdrawn position. The entire visor assembly is configured to be aesthetically pleasing and relatively inexpensive to produce in terms of component and production costs.
