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.
A seat-positioning mechanism of the type including an elongated housing having a rod slidably received therein for movement in either direction with respect to said housing with friction lock means received in said housing, said friction lock means having a locked position canted about a fulcrum to be in frictional engagement with said rod, thereby frictionally restraining said rod against movement in at least one direction with respect to said housing, and an unlocked position wherein said friction lock means is disposed substantially perpendicular to said rod and out of frictional engagement therewith to permit free movement of said rod with respect to said housing to any selected position and biasing means operatively connected to said friction lock means to urge said friction lock means toward the locked position and cam means capable of canting said friction lock means into said unlocked position;
A seat-positioning mechanism comprising:
A seat-positioning mechanism of the type including an elongated tubular housing of predetermined cross section, said housing having a rod slidably received therein for movement in either direction with respect to said housing with locking elements having a cross section substantially the same as said predetermined cross section, said locking elements having a locked position tilted about a fulcrum to be in frictional engagement with said rod, thereby frictionally restraining said rod against movement in at least one direction with respect to said housing and an unlocked position wherein said elements are disposed substantially perpendicular to said rod and out of frictional engagement therewith to permit free movement of said rod with respect to said housing;
