A third power mechanism (28) moves the mirror unit (14) into a desired adjusted position about horizontal and vertical axes. An electronic control controls the operation of the first power mechanism (20) and the second power mechanism (24) and the third power mechanism (28) to control the powered pivoting of swingable structure (16) and to control the generally horizontal movement of mirror housing (12) to various positions located between inner and outer limiting positions and to adjust the mirror about vertical and horizontal axes.
Abstract:
A mirror assembly for use on an automotive vehicle comprises a support base for fixedly mounting the mirror assembly to the vehicle. The mirror assembly further includes an upper and lower support arm, each extending longitudinally between a first end and a second end. A collar having an upper chamber and a lower chamber is fixedly secured to the first ends of the support arms and pivotally coupled to the support base for pivoting the support arms about a generally vertical axis between an operative position extending laterally from the vehicle and a folded position pivoted adjacent and generally parallel to the vehicle. A housing is slidably coupled to the second ends of the support arms and slidable therealong between a retracted position adjacent the first ends and an extended position adjacent the second ends. A mirror pane is operatively coupled to the housing for providing an adjustable reflective view from the mirror assembly. The mirror assembly further includes a drive mechanism housed within the lower support arm and lower chamber of the collar and operatively coupled to the housing by a clutch mechanism for moving the housing between the retracted position and the extended position. The mirror assembly also includes a pivot mechanism housed within the upper chamber of the collar and operatively coupled to the support base for pivoting the support arm between the operative position and the folded position.
Abstract:
A rearview mirror assembly having a pivot structure and first and second pairs of helical structures consisting of shape memory alloy wires which serve to adjust the position of the mirror. The wires may be individually heated by conducting an electrical current to effect the contracted memory position. When the current is switched off, a wire cools and can easily be stretched to mechanically transform the wire to a martensitic phase.
Abstract:
A mirror assembly for use on an automotive vehicle comprises a support base for mounting the mirror assembly to the vehicle. A support arm extends longitudinally between a proximal end pivotally coupled to the support base and an opposite distal end. The mirror assembly further includes a housing coupled to the support arm and slidable between a retracted position adjacent to the proximal end and an extended position adjacent to the distal end and spaced from the proximal end. A glass mirror pane is operatively coupled to the housing for providing a reflective view from the mirror assembly. The mirror assembly also includes a drive mechanism coupled between the Support arm and the housing for providing, both power actuated and manual sliding movement of the housing along the support arm between the retracted position and the extended position. The drive mechanism includes a drive screw rotated by a motor for engaging and driving a drive nut coupled to the housing along the longitudinal length of the drive screw. A clutch mechanism allows the drive nut to freely rotate about the drive screw to manually adjust the position of the housing along the support arm. The mirror assembly further includes a pivot mechanism coupled between the support base and the support arm for providing both power actuated and manual pivoting movement of the support arm between an unfolded position extending laterally from the vehicle and a folded position pivoted adjacent and generally parallel to the vehicle.
Abstract:
A rearview mirror assembly comprises a mirror unit, a mirror unit support, and a central connection between the mirror unit and support mounting the mirror unit for pivotal movement about first and second generally intersecting perpendicular axes. A first arm is mounted on the support for pivotal movement about the first axis and connected with the mirror unit for limited pivotal movement about the second axis at a position spaced from the first axis. A second arm is mounted on the support for pivotal movement about the second axis and connected with the mirror unit for compound movement for compound movement which includes limited lateral movement with respect to the first axis and pivotal movement about an axis which is either coincident with or slightly angularly related with the first axis depending upon the position of relative lateral movement. First and second power-transmitting surfaces on the first and second arms respectively are arcuate about the first and second axis respectively. First and second power-operated rotary members are constructed and arranged with respect to the first and second power-transmitting surfaces respectively (1) to move under power in peripheral rolling contact therewith to effect movement of the first and second arms respectively and (2) to move under power in peripheral sliding relation therewith in the event that movement of the first and second arms respectively is otherwise prevented.
Abstract:
A vehicle mirror assembly comprising a housing assembly, a mirror unit, a support assembly to support the housing assembly thereon, a power operated pivot assembly between the support assembly and the housing assembly to enable the housing assembly to be pivoted with respect to the support assembly about a generally upright axis (1) between an operative position and a folded position in response to the power operation of the pivot assembly and (2) from the operative position thereof in either direction in response to an unwanted impact blow applied in either direction thereto. A spring biased pivotal control system is disposed between a movable tubular member of the pivot assembly and the support assembly to provide a control resistance to pivotal movement of the movable tubular member and hence the housing assembly connected thereto. A spring biased indexing system is disposed between a motion transmitting member and the movable tubular member to (1) transmit the movement of the motion transmitting member under power to the movable tubular member to thereby move the housing assembly between the operative and folded positions with the control system providing a control resistance and (2) allow the movable tubular member to be moved from the operative position relative to the motion transmitting member in response to an unwanted impact blow applied to the housing assembly in either direction to move the housing assembly from the operative position with the indexing system providing an indexing resistance to such movement which is independent of the control resistance.

Abstract:
An afocal rearview mirror assembly for a motor vehicle having a side door and a dashboard includes a housing attached to the motor vehicle adjacent the side door and dashboard. The housing has a low-profile, rounded external portion and an internal portion. A selectively movable reflective element is enclosed within the housing, and has opposed curved surfaces for reflecting unfocused light rays from outside the external portion through the internal portion of the housing. A selectively movable lens is enclosed within the internal portion of the housing for controlling light transmitted from the selectively movable reflective element to an occupant of the motor vehicle. The selectively movable lens can converge the unfocused light rays reflected from the selectively movable reflective element to a focused image observable by the occupant of the motor vehicle.
