Vehicle exterior rear view mirror actuator

The invention relates to an adjustment device for the wing mirror of a The motor vehicle having a drive housing on which via a central ball spherical bearing a mirror glass support is mounted, the tooth with intersecting bands, Chains or the like is that the shell-like drive housing clasping two in engagement with the driven gear wheels in the drive housing arranged drive motors are stationary and an electrical contacting device for the mirror glass for supplying electric power for heating the mirror, the Spiegelabdunkelung or the like.

Usually, in such, also called glass drives Verstellvorrichungen the devised such that the contacts of the mirror glasses for Heating or the like to be contacted from the outside. This means that special cables must be supplied from the outside, not only the structure and the assembly difficult, but also the tilt adjustment of the hinder the mirror glass to the mirror glass support.

The invention is therefore based on the object, an adjustment of the above kind set forth so that both the production as well installation creates a simpler contacting the mirror glass without disturbing Outer lines is possible.

To achieve this object the invention provides that the contact-making lines through the central axis of the ball cup bearing are guided.

The invention makes use of the special nature of the drive transmission via which intersecting tooth belts, chains or the like, so while ensuring that the joint ball of the mirror glass support in the Gelenkkalotte the drive housing is held and not easily fall out, which are customary in Axis of the ball cup bearing provided screw or are snap connections unnecessary. By eliminating this screw, using the mirror glass support and the drive housing kept together were to have the possibility, openings in the joint ball provide and Gelenkkalotte through which the contact terminal lines can be guided.

In development of the invention it has proven to be especially effective, when on a drive housing, preferably in the aligned apertures the joint ball and the ending Gelenkkalotte tube is formed, in the contact connection lines are guided, in turn, with a lateral Plug part are connected to the connector housing. The serving for guiding Tube prevents the connection cables in contact with moving parts the drive devices can access and supports beyond the Contact connection lines preferably with at mating contacts on the mirror glass adjacent spring contact tongues are provided. is a result of the support in the pipe this particular elastic contact particularly easy to implement.

Further advantages, features and details of the invention result from the following description of an embodiment and with reference to the Drawing. They show:<dl tsize="6"><dt>Fig. 1</dt><dd>A perspective view of the adjustment device according to the invention from behind and</dd><dt>FIG. 2</dt><dd>an angled section along the line II - II in Fig. 1.</dd></dl>

In the figures, one recognizes the drive housing 1, in the mirror glass support 2 facing front wall 3 a Gelenkkalotte 4 is formed, in which a joint ball 5 engages, is formed on the mirror glass support 2nd The one with a circumferential annular wall 6 provided mirror glass substrate 2 is what is shown in Embodiment with two intersecting elastic metal strips 7 and 8 provided that are at least partially designed as a toothed belts. 9 and 10 In these toothed belts 9 and 10 engage the driven gears 11 of the individual not shown, arranged in the interior of the drive housing 1 the electrical Driving devices 12 and 13, using which the mirror glass carrier 2 against the drive housing 1 and two perpendicularly intersecting axes is pivotable. The Gelenkkalotte 4, with the joint shell located therein and the joint ball 5 are provided with relatively large apertures 14 and 15, through which the contact terminal lines 16 and 17 for the side mirrors, the Spiegelabdunkelung or the like, are performed. This contact terminal lines 16 and 17 are arranged in a through the axis of the drive housing 1 Pipe 18 out which it is based and from contact with moving parts the drive means protects. Over on the inside of the drive housing arranged contact tongues 19 and 20, the contact connecting leads 16 and 17 with the contacts 21 of the side of the drive housing molded plug part 22. or executed "in one piece". contacting the mating contacts on the mirror glass 23 is not shown in the drawing can by connected to the contact terminal lines 16 and 17 spring contact tongues 24 and 25 take place.

The size of the openings - in the present case indeed only possible are, because the holding together of the drive housing 1 and the mirror glass support 2 takes place via the toothed belts 9 and 10 - is chosen such that in the extreme angular positions of the mirror glass carrier relative to the drive housing an aligned region of the two openings in the middle of the Contact connection lines persists. 16 and 17
