Abstract
Abstract This invention relates to an electrically operated adjustable apparatus for a motor vehicle rear view mirror having a mirror casing, and included therein, a mirror support to which the mirror casing is connected via a first fixed junction point, and on a straight line through this first junction point and parallel thereto are two more junction points, the distance between the mirror casing and mirror support being electrically variable. The first fixed junction point is arranged to be very far from both further junction points, making a stable housing of the mirror support possible. Since both of the further junction points can be arranged on a small edge of the mirror support beside one another, it is possible to design the means for driving of both the two further junction points on the side of the mirror support which permits the mirror housing to be flat. The driving means are located preferably in a side housing unit in the vicinity where the mirror housing is connected with the motor vehicle. The adjustable device makes it possible to use light mirror housings made of plastic without solid metal supports.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
173 words
An electrically operated adjustable apparatus for a motor vehicle rear view mirror having a mirror casing and including therein a mirror support to which the mirror casing is connected via a first fixed junction point and two further junction points, one of said further junction points being located on a first straight line through said first fixed junction point and said two further junction points being located on a second straight line which is perpendicular to said first straight line, further including electric motor drive means linked by gear means to said further junction points for moving said mirror support so as to vary the distance between the mirror casing and mirror support, the electric motor drive means and the gear means being located in a separate housing of the casing on one side of said support, the housing having a housing wall at said one side thereof containing two slots therein in which driving means of said gear means for said further junction points are mounted for sliding movement along said slots.
Claim 2
Dependent Claim
173 words
An electrically operated adjustable apparatus for a motor vehicle rear view mirror having a mirror casing and including therein a mirror support to which the mirror casing is connected via a first fixed junction point and two further junction points, one of said further junction points being located on a first straight line through said first fixed junction point and said two further junction points being located on a second straight line which is perpendicular to said first straight line, further including electric motor drive means linked by gear means to said further junction points for moving said mirror support so as to vary the distance between the mirror casing and mirror support, the electric motor drive means and the gear means being located in a separate housing of the casing on one side of said support, the housing having a housing wall at said one side thereof containing two slots therein in which driving means of said gear means for said further junction points are mounted for sliding movement along said slots.
