  • Patent number: 5029052
    Abstract: A vanity mirror for mounting in a vehicle sun visor including a housing and an external connector provided in the sun visor, a lamp section including a tubular electric lamp provided in a recess formed in the housing and an internal connector provided in the housing. Two contact members for supporting the bases on both sides of the electric lamp are provided and the end of one extremity of these contact members are formed into electric lamp supporting portions. The other end of at least one of these contact members is made into a connecting piece for connecting the external connector thereto. Also, the internal connector is formed by placing a connecting piece connected to the other end of the other contact member in parallel with the connecting piece of the first contact. With this construction use of vehicle as a ground is avoided so that the supporting structure of the mirror with the lamp may be formed of a nonmetallic lightweight material.

  • Patent number: 4909562
    Abstract: A visor/mirror assembly comprising a visor subassembly having a visor, and a vanity mirror subassembly mounted to the visor. The vanity mirror subassembly comprises a mirror supported by a mirror frame on the visor, and a mirror cover hingedly mounted to the mirror frame for swinging between a closed position and an open position with respect to the mirror. A locking mechanism normally holds the mirror cover in the closed position against the force of a spring energizing the mirror cover toward the open position. Connected between the mirror frame and the mirror cover is a fluid damper which acts in opposition to the force of the spring for retarding the pivotal displacement of the mirror cover from the closed to the open position when the mirror cover is unlocked by finger pressure on the locking mechanism. With its momentum so reduced, the mirror cover comes to rest in the open position without shock or noise.

  • Patent number: 4878391
    Abstract: A mechanism particularly well suited for converting bidirectional rotation, as of a reversible electric motor or a hand crank, into the linear up and down motion of a windowpane relative to the frame of a passenger car door. Included is an elongate guide rail gently curved longitudinally to conform to the vertical curvature of the vehicular door and providing a vertical guideway on its convex side. A wire rope or cable is looped about a pair of terminal guide pulleys or nonrotatable guides on the opposite ends of the guide rail. One of the two stretches of the cable is coupled to a windowpane carriage which is coupled to the windowpane for joint up and down movement therewith along the guideway. A drive mechanism including a drive reel is mounted to the guide rail and coupled to the other stretch of the cable for bidirectionally driving the windowpane carriage along the guideway. The drive mechanism is compactly disposed on the concave side of the guide rail for minimal space requirement.
