Rear under view mirror apparatus for automobiles
First Claim
1. An under view mirror apparatus for automobiles, comprising a driving device that is secured to a member at a rear side of a roof of an automobile, a driving arm that is rotatable connected at one end to an output shaft of the driving device, a driven arm that is rotatable connected at one end to the member, said driven arm being spaced away from the driving arm and possessing a length that is different from the driving arm, and a mirror housing connected to the driving arm through a universal joint and connected to the driven arm through a connection device having two shafts through which the driven arm is rotatable with respect to the mirror housing, the shafts being disposed at a right angle to each other, and the mirror housing retaining a mirror, wherein the driving arm is shaped like a horizontally thrown V when viewed from a direction perpendicular to the plane in which the driving arm is disposed, the driving arm possessing a length longer than that of the driven arm, both the driven and driving arms being disposed with a level difference being provided therebetween.

Abstract
A driving arm (5) that is connected directly to an output shaft (4) of an electric motor (3) is connected to a mirror housing (8) through a ball joint (10). On the other hand, a driven arm (6) is connected to the mirror housing (8) through a connection device (11) having two orthogonally intersecting shafts (12, 14). The both arms (5, 6) are disposed in parallel with each other with a level difference being provided therebetween. As a result, the under view mirror is held in an attitude preferable for the stored position thereof and held in an attitude preferable for the use position thereof, when it is moved to the use position.

7. An under view mirror apparatus mounted rearward of an automobile so as to confirm a rear under field of view thereof from a driver'"'"'s seat, comprising;
-
a base member adapted to be mounted rearward of an automobile, a mirror housing movably supported with respect to the base member and selectively positionable from a stored position inside the base member to a use position wherein the mirror housing transfers a rear under field of view of the automobile to a driver'"'"'s seat side, and actuating means for moving the mirror housing between the stored position and the use position, the actuating means including a power source mounted on the base member, a driving arm operatively connected at one end with the power source and at the other end with the mirror housing through a universal joint so as to be reciprocable when the power source is actuated, and a driven arm connected at one end with the base member and at the other end with the mirror housing through pivotal means, the mirror housing being located right below the base member and directed downward when in the stored position, and the mirror housing being directed obliquely forward and downward when in the use position. - View Dependent Claims (8)

9. An under view mirror apparatus for automobiles, comprising a mirror housing that retains a mirror, a driving device secured to a member at a rear side of a roof of an automobile for providing a driving force to move the mirror housing between a stored position and a use position, a driving arm having a first end and a second end, the first end of the driving arm being connected to an output shaft of the driving device, the second end of the driving arm being connected to the mirror housing by way of a connection joint, a driven arm having a first end and a second end, the first end of the driven arm being rotatably connected to the member and the second end of the driven arm being connected to the mirror housing through a connection device which permits said mirror housing to rotate relative to the driven arm about two axes located transverse to one another as said mirror housing is moved between the stored position and the use position during operation of the driving device, wherein the driving arm possesses a length greater than that of the driven arm.
