1. A mirror system comprising a reflective element assembly which is pivotable between an unfolded position and a folded position, comprising:
- a base defining a periphery, and having a pivot assembly having a pivot center and comprising;
a first set of bosses spaced a first radial distance away from the pivot center, and a first set of recesses spaced at least one radial detent distance from the pivot center, the at least one radial detent distance defining a circular path that extends beyond the periphery of the base; and
a second set of bosses and recesses spaced at least one radial distance from the pivot center which is different than the first radial distance, the recesses having first ends and second ends, wherein each end has a wall defining an end of travel range whereby, as the reflective element assembly is moved between the folded and unfolded positions, the second set of bosses abut a wall and are prevented from further movement within the second set of recesses;
wherein the first set of bosses and recesses engage cooperatively with each other in the unfolded position to maintain the reflective element assembly in the unfolded position; and
wherein during manual overtravel of the pivot assembly, the first set of bosses and recesses is moved out of engagement and the second set of bosses and recesses assumes the support of the reflective element assembly from the first set of bosses and recesses.

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.

7. A mirror system comprising a reflective element assembly which is pivotable between an unfolded position and a folded position, comprising:
-
a support frame for supporting a reflective element; a base defining a periphery, for attachment to a vehicle, and coupled with the support frame through a pivot assembly having a pivot center, the pivot assembly comprising; a first set of bosses and contact regions spaced a first radial distance away from the pivot center, the first set of contact regions being spaced at least one radial detent distance from the pivot center, the at least one radial detent distance defining a circular path that extends beyond the periphery of the base; and a second set of bosses and contact regions spaced at least one radial distance from the pivot center which is different than the first radial distance, the second set of contact regions comprising annular slots spaced at least one radial slot distance from the pivot center; wherein the first and second contact regions each have a first contact surface, and a second contact surface spaced vertically away from the first contact surface; and wherein during pivoting of the support frame relative to the base, the engagement of the first and second set of bosses is transferred between the first contact surfaces and the second contact surfaces to transfer engagement of the first set of bosses with the first set of contact regions to engagement of the second set of bosses with the second set of contact regions. - View Dependent Claims (8, 9)
