Abstract

The invention relates to a smoothly operating tilting device (11), in particular, for the support plate (12) of a motor-adjustable motor vehicle exterior mirror, whereby the plate (12) has an articulating joint to a housing (13), for a rigid mounting. A drive motor (17) is provided, for each of the both, orthogonal to each other (although arrangeable in any relative spatial disposition) tilting directions, which are connected to, at least in parts, flexible positioning rods (18). The above run in an arched guide (22) and are turned from the plane parallel to the plate (12) in to the transverse direction, in order to bridge the mounting gap and connect with an articulated joint to the face of the back side, or the interior of the plate (12), for the transfer of pushing or pulling movements.

Claims

1. A motorized tilting device (11) for a plate (12)—

which has a mechanical connection to a motor (17) via a (word missing] curved guided through a housing (13) fixed to an object,

characterized in that the plate (12) is a support plate (12), particularly for receiving a motor vehicle mirror, which is tiltable in relation to the housing (13) and is mounted on its back side on the housing (13) and is linked to an adjustment rod (18), which runs, using two flexible regions (22) on both sides of the central toothed region (21), through curved guide (24) and then through guide openings (26) pointing toward the plate (12), exiting out of the housing (13), where its free front ends (27) are linked using articulated joints to two points, which are diametrically opposite in relation to the mounting, on the back side (20) of the plate (12).

2. The tilting device according to claim 1,

characterized in that the central toothed region (21) of the adjustment rod (18) turns into an end piece (25), which is connected to the plate (12) using an articulated joint and is stiff in contrast to the flexible region and which exits out of the guide opening (26) in an orientation fixed in relation to the housing, on both sides via a flexible region (22), which runs in a curved guide (24).

3. The tilting device according to claim 1 or 2, characterized in that two adjustment rods (18, 18′

), which may be moved independently from one another, are positioned in different planes in the housing (13) and are connected in mutually orthogonal orientation to the plate (12).

4. The tilting device according one of the preceding claims,

characterized in that an articulated connection (28) of the front end (27) of the adjustment rod (18) is provided behind or in the plate (12).

5. The tilting device according to one of the preceding claims,

characterized in that a spherical cap-spherical shell combination (15-16) is provided as an articulated mounting of the plate (12) on the housing (13).

6. The tilting device according to one of the preceding claims,

characterized in that a deformable but only slightly compressible material is used for the deflection region (22) of the adjustment rod (18).

7. The tilting device according to one of the preceding claims,

characterized in that the adjustment rod (18) has regions in the deflection region (22) which are weakened over their cross-section.
