Patent attributes
A vehicular exterior rearview mirror assembly includes a mirror head pivotally mounted at a mounting arm configured for attachment at a side of a vehicle. The mirror head includes a reflective element. A powerfold actuator is operable to pivot the mirror head relative to the mounting arm between at least a folded position and a drive position. The powerfold actuator includes a primary detent that is engaged to maintain the mirror head at the drive position when the mirror head is pivoted via the powerfold actuator to the drive position. The powerfold actuator includes a secondary detent. Following pivoting via the powerfold actuator of the mirror head to the folded position, when the mirror head is manually pivoted from the folded position to the drive position, the primary detent is disengaged and the secondary detent is engaged to maintain the mirror head at the drive position.
