Abstract: A foldable rearview mirror assembly for a vehicle is disclosed. The assembly comprises: a mounting bracket mountable to a vehicle, the mounting bracket having a base with detent features disposed on a detent circle on the base; a mirror head frame rotatably mounted to the mirror base for rotation about a mirror head axis, the frame having detent features to match the detent features of the base, the detent features of the base and the frame forming a detent system, the detent system having at least a drive position. The frame is shaped to provide an aperture to receive either of: a manual fold insert; or a power fold mechanism having a clutch mechanism, the aperture at least partially inboard in a radial direction with respect to the detent features on the frame whereby at least the clutch mechanism of the power fold mechanism can be accommodated to operate on a smaller radius than that of the detent features.

Abstract: A vehicle external rear view mirror assembly comprising a bracket and a mirror head, a pair of parallel outer arm assemblies (20, 20?) having a front portion and a rear portion, the front portion having a rack (28, 28?), a pair of parallel inner arm assemblies (40, 40?) and extending into respective outer arm assemblies (20, 20?), each inner arm assembly (40, 40?) having a front portion and a rear portion, a pair of driving pinion gears (50, 50?), each engaging a respective rack (28, 28?), a pinion drive shaft (53), a drive motor (60), and a gear train, the drive motor (60) driving the inner arm assemblies (40, 40?) to move telescopically with respect to their respective outer arm assemblies (20, 20?), wherein each outer arm assembly (20, 20?) is recessed back from the distal end towards the bracket to allow the pinion drive shaft assembly to travel towards the bracket behind the front portion of the outer arm assembly (20, 20?).
