Device for indexing the arm or casting of a vehicle rearview-mirror
First Claim
1. In a device for indexing an arm supporting a rearview mirror in which one of the ends of said arm is pivotally mounted on a support member and pivots about a first pivot axis, said support member being adapted to be mounted on a motor vehicle, the improvement comprising:
- a flange member formed of a resilient material and pivotally mounted on said support member, said flange member further pivoting about a second pivot axis parallel to said first pivot axis and spaced a predetermined distance therefrom;
a partial right circular cylindrical surface on said arm, said partial right circular cylindrical surface being disposed between said first and second pivot axes and curved about said first pivot axis;
a first and second abutment means extending from said flange member and each engaging said partial right circular cylindrical surface;
a recess in said arm, said recess being selectively alignable with said first abutment means in a first predetermined angular position of said arm about said first pivot axis; and
a third abutment means extending from said partial right circular cylindrical surface and selectively engageable with said second abutment means in said first predetermined angular position of said arm and in a first range of angular positions on either side of said first predetermined angular position such that said third abutment means cooperates with said second abutment means to resiliently deflect said flange member when said arm is in said first range of angular positions and pivots said first abutment means into said recess in said first predetermined angular position, said third abutment means thereby inhibiting rotation of said arm to and from said first predetermined position.

Abstract
Device for indexing an arm supporting a rearview mirror or a rearview mirror casing, in which one of the ends of the indexing member is mounted for pivoting about an axis on the support member. The device includes a flange member of a deformable material provided in its center with a resting point by which it rests against the support member on which it is pivotally mounted and at its ends, with two resting points, one of which has locking provisions for locking it with the indexing member, the other cooperating with the indexing member for stretching the flange during the locking and unlocking operations only.

8. An indexing device for indexing a rearview mirror with respect to a vehicle body comprising:
-
a support member adapted to be mounted to said vehicle body having a support branch with an indexing axis therethrough spaced from said vehicle body, and further having support centering means with a flange axis spaced intermediate said vehicle body and said indexing axis and parallel thereto; an indexing member having a mirror end supporting one of a mirror and a mirror case, said indexing member further having an indexing end pivotably supported by said support branch about said indexing axis, said indexing end further having a cylindrical surface partly thereabout with an indexing recess therealong and an indexing abutment thereon spaced circumferentially from said indexing recess; and a flange member captured by and between said support member and said cylindrical surface, said flange member having flange centering means cooperating with said support centering means to center said flange member about said flange axis and further having a first and a second flange abutment spaced about said flange axis and extending towards and slidably engaging said cylindrical surface; whereby said cylindrical surface cooperates with one of said first and second flange abutments to establish an unlocked position of said indexing member about said indexing axis, and wherein said indexing recess cooperates with one of said first and second flange abutments while said indexing abutment cooperates with the other of said first and second flange abutments to define a locked position of said indexing member at a predetermined angular distance from said unlocked position. - View Dependent Claims (9, 10, 11)
