Abstract

A mechanically adjustable rear-view mirror has a mounting unit (7) to attach it to a truck. A servomotor unit (20) is mounted between a base plate (18) attached to the mounting unit and a support plate (19) running roughly parallel to the base plate. The base plate is firmly attached to a housing (1) containing the mirror (3). The servomotor unit (20) contains two servomotors (31, 32) which are attached to the support plate (19) and connected to the base plate (18) via actuators (37, 38) and universal joints (41, 42). In addition, a bearing support (43) which is also connected to the base plate (18) by a universal joint (44) is attached to the support plate (19). A pair of universal joints (41, 44 or 42, 44) form a pivot axis for the opposite servomotor (31, 32). This construction is simple, is easy to install and is very stable.

A mechanically adjustable rear-view mirror for motor vehicles, comprising a housing (1) holding a mirror glass (3), a mounting unit (7) for securely fixing to the vehicle, a base plate (18, 18') which is fixed relative to the mounting unit (7) and with a servomotor unit (20, 20') mounted between the base plate (18, 18') and the housing (1), said servomotor unit comprising two servomotors (31, 32;

31', 32') with actuators by which the housing (1) is pivoted around two pivot axes (45, 46) which lie practically perpendicular to one another, wherein a support plate (19, 19') immediately next to the mirror glass (3) in the housing (1) is securely mounted relative to the housing (1), the servomotors (31, 32;
31', 32') are mounted to said support plate (19, 19') between said support plate and the base plate (18, 18'), the actuators of the servomotors (31, 32;
31', 32') are each connected to the base plate (18, 18') by a universal joint (41, 42), a bearing support (43, 55) is mounted on the support plate (19, 19') and is connected to the base plate (18;
18') by means of a universal joint (44;
58), and the universal joint (44;
58) of the bearing support (43;
55) and one universal joint (41, 42) of each servomotor (31, 32;
31', 32') form the pivot axes (46, 45) of the other servomotor (31, 32:
31', 32').
