SEAT POSITIONER ABSTRACT OF THE DISCLOSURE A seat-positioning mechanism is disclosed and is of the type which includes an elongated housing having a rod slidably received therein for movement in either direction with respect to the housing. The housing contains friction lock elements which have a locked position canted about a fulcrum to be in frictional engagement with the rod. This engagement frictionally restrains the rod against the movement in at least one direction with respect to the housing. The friction lock elements have an unlocked position wherein the friction lock elements are disposed substantially perpendicular to said rod and out of frictional engagement therewith to permit free movement of the rod with respect to said housing to any selected position. The housing also includes a spring operatively connected to the friction lock element to urge the friction lock element towards the locked position. A cam, which is capable of tilting the friction lock element into the unlocked position is also included within the housing. A positioning element is located between the friction lock element and the spring. The positioning element is capable of preventing movement of the friction lock elements along the rod in the canted position upon actuation of the cam.
