A drive component comprising a first rotation part and a second rotation part arranged to rotate together around a common central axis with respect to each other around that central axis. The drive component further comprises a rotation limiter operative between the two rotation parts, which limits rotation between them.

The rotation limiter is so arranged that when the first rotation part is driven to rotation, the first rotation part after traversing a free angular stroke carries the second rotation part in a mutual angular position determined by the rotation limiter, i.e. the carry-along angle, along in rotation. The rotation limiter comprises an indexer energized by rotation of the first and/or second rotation part, so that in successive driving cycles on the drive component the carry-along angle is indexed and the rotation parts in successive driving cycles differ in mutual angular position at carry-along.

A vehicular exterior rearview mirror assembly includes a mirror head adjustably disposed at a mounting structure. An electro-optic reflective element is attached at an attachment element that attaches at an electrically powered actuator disposed in the mirror head. The attachment element includes a protruding portion that is at least partially received at a notched region of the rear glass substrate when the reflective element is disposed at the attachment element. An outer surface of the protruding portion of the attachment element corresponds with the second perimeter edge of the rear glass substrate at the notched region of the rear glass substrate. With the electro-optic reflective element disposed at the mirror head, the outer surface of the protruding portion provides a curved transition from an outer surface of the mirror head toward the first surface of the front glass substrate.

A vehicular exterior rearview mirror assembly includes a mirror head mounted at a mounting structure. An electro-optic reflective element is attached at an attachment element that attaches at an electrically powered actuator accommodated by the mirror head. The reflective element has a front glass substrate having a first thickness less than 2.3 mm and a rear glass substrate having a second thickness less than or equal to 1.6 mm. The first and second perimeter edges of the glass substrates combine to provide a curved transition from a first surface of the front glass substrate and an outer surface of the mirror head. The mirror head includes a protruding portion that is at least partially received at a notched region of the rear glass substrate. An outer surface of the protruding portion corresponds with the second perimeter edge of the rear glass substrate at the notched region.

An apparatus and method for controlling side-view mirrors, adjusting the side-view mirrors on the basis of a lane while a driving direction is changed, and provide a driver with changed viewing angles. Thereby, there are effects capable of securing a field of view of a driver for a lane for movement, improving a blind spot, providing the same viewing angle of the side-view mirrors as a straight driving situation, and an effect of enabling other vehicles with ease to prevent occurrence of an accident and to improve safety of the vehicle.

Systems and methods are provide for an actuator system for a rear view device of a motor vehicle, configured for adjustment of a component when being connected to the actuator system The actuator system may include a drive system arranged to rotate a bayonet gear, which is coupled via at least one engagement element to a latching barrel to axially move or rotate the latching barrel along or around a rotational axis, wherein the latching barrel is configured to engage into at least one of two worm gears or to rotate the engaged worm gear when being moved or rotated. The latching barrel may be cylindrically shaped with a cylindrical surface as an engagement surface and oppositely arranged first and second sides each directed towards one of the two worm gears.

A vehicular exterior rearview mirror assembly includes a base portion configured for attachment at an exterior portion of a vehicle, a mirror head having a mirror reflective element, and an actuator within the mirror head. When the mirror actuator is electrically operated, the mirror actuator moves the mirror head and the mirror reflective element together and in tandem relative to the base portion. The mirror reflective element is adhesively attached at a mirror back plate. The mirror back plate is attached at a head mounting plate, which is attached at the mirror actuator. A service recess is at and between the mirror back plate and the head mounting plate and is accessible from exterior the mirror head. The service recess is configured to enable detachment of the mirror back plate, with the mirror reflective element adhesively attached thereto, from the head mounting plate.
