Abstract:
A vehicular exterior rearview mirror system comprises a reflective element assembly, a base frame coupling the reflective element assembly to a vehicle, a support arm for coupling the reflective element assembly to the base frame, and a pivot connection for pivotally coupling the support arm to one of the base frame and the reflective element assembly. The pivot connection comprises a pedestal having at least two detent ribs, and an opening for receipt of the pedestal therethrough having at least two detent channels. Pivoting of one of the support arm relative to the base frame and the reflective element assembly relative to the support arm moves a first one of the at least two detent ribs out of a first one of the at least two detent channels and into a second one of the at least two detent channels.
Abstract:
A vehicular external rearview mirror system comprises a support arm pivotally connected to a base assembly attached to the vehicle. The pivot connection comprises an assembly of rotating plates separated by ball bearings and operated by a powerfold assembly. During normal operation of the mirror system, the ball bearings remained seated in bearing seats to enable the plates to rotate as a single unit when the powerfold assembly is actuated. However, manual folding or unfolding of the mirror system urges the ball bearings out of their bearing seats to travel along a raceway in one of the plates to facilitate the rotation of the plates relative to each other.
Abstract:
A vehicular external rearview mirror system comprises a twin-arm assembly comprising a pair of parallel support arms connected at one end to a base attached to the vehicle and movably connected at another end to a reflective element assembly through a movable support bracket. The support bracket supports a reflective element assembly and is attached to the twin-arm assembly through a pair of integral bearings which translate along the arms to extend or retract the reflective element assembly. In one embodiment, the bearing imparts a friction force to the arm to enable the bracket to be moved along the arm under the influence of an extension/retraction force, but to maintain the bracket at a selected position along the arm when the force is removed. In another embodiment, the bearing is adapted for frictionless translation of the bracket along the arms under the influence of a powerextend actuator. In yet another embodiment, the bearing is integrated into the movable support bracket for frictional support of the bracket on the arms.
Abstract:
An exterior rearview mirror system for a vehicle includes an exterior rearview mirror assembly and a unitary indicator module disposed at the exterior rearview mirror assembly. The unitary indicator module includes a plurality of illumination sources disposed behind an at least partially light transmitting portion of the unitary indicator module. Light emitted by any of the illumination sources passes through the at least partially light transmitting portion for viewing by a driver of the equipped vehicle. The unitary indicator module is responsive to a control signal to indicate to the driver of the equipped vehicle a detected presence of another vehicle at least one of alongside the equipped vehicle and rearward of the equipped vehicle. The unitary indicator module is operable to indicate a degree of hazard at least one of alongside the equipped vehicle and rearward of the equipped vehicle.
Abstract:
An exterior rearview mirror system for a vehicle includes an exterior mirror assembly that is mountable at an exterior side of a vehicle and has an inboard portion that is viewable by a driver of the vehicle when the mirror assembly is mounted at the exterior side of the vehicle. A blind spot indicator is disposed at the inboard portion of the mirror casing of the mirror assembly. The blind spot indicator comprises at least one illumination source for indicating to the driver a detected presence of an object alongside of and/or rearward of the vehicle. The indicator may comprise a unitary indicator module that is mountable at the inboard portion of the mirror assembly. The indicator module includes an illumination source and circuitry and is connectable to an electrical connector.
Abstract:
A vehicular mirror system comprises a base frame attached to a motor vehicle and a support frame supporting a reflective element assembly and pivotally attached to the base frame for pivoting the reflective element assembly between a folded position and an unfolded position. A detent assembly intercommunicating the support frame and the base frame comprises a plurality of spaced bosses and recesses positioned at different radii and enabling pivoting of the support frame with minimal vertical displacement of the support frame relative to the base frame.
Abstract:
A rearview mirror tilt actuator comprises a clutch assembly that selectively transfers torque from an actuator motor to one of at least two output shafts based upon the speed of the motor. One output shaft can pivot the mirror about a first axis of rotation; another output shaft can pivot the mirror about a second axis of rotation. One output shaft can pivot the mirror housing; the other output shaft can extend and retract the mirror housing. At a low speed, the clutch assembly is disengaged, thus only the first output shaft is activated. At a high speed, the clutch assembly is engaged, thus both output shafts are activated The mirror assembly described herein also has an improved mass configuration which allows for lower moments of inertia in the direction of mirror travel.
Abstract:
A vehicular mirror assembly comprises a base, a mirror housing, and an actuator. The mirror housing has a reflective element therein, and is coupled with the base for at least a normal path of movement between a retracted position where the mirror housing is adjacent the base and an extended position where the mirror housing is distal to the base. The actuator is operatively mounted between the base and the mirror housing for selectively moving the mirror housing with respect to the base through the normal path of movement. The actuator comprises a motor having a rotatable motor shaft, a gear assembly coupled with the motor shaft and rotatable with rotation of the motor shaft, and a rotatable drive shaft coupled with the gear assembly and the mirror housing for moving the mirror housing through the normal path of movement with rotation of the drive shaft. The mirror housing can be moved between the extended and retracted positions by rotation of the drive shaft and the gear assembly independent of the rotation of the motor shaft, and torque developed by the gear assembly resulting from the rotation of the motor shaft is comparable to the torque developed by the gear assembly resulting from the rotation of the drive shaft.
Abstract:
An exterior rearview mirror assembly of a vehicle includes a mirror casing and a reflective element and an indicator module having a housing, a circuit element and a lens element. The circuit element includes at least one light emitting diode. When the light emitting diode is powered, light emitted by the light emitting diode passes through the lens element. The housing includes at least one attachment element for mechanically attaching the indicator module at the mirror assembly. The lens element is disposed at an aperture of the mirror casing, whereby the lens element is viewable at the exterior of the mirror assembly and the housing of the indicator module is substantially concealed by the mirror casing. The indicator module provides a blind zone indicator that is operable to indicate to a driver of the vehicle that an object or other vehicle is detected at a side region of the vehicle.
