1. A latch mechanism assembly for a slidably adjustable system comprising:
- a latch body having a latching tooth portion disposed at a first end of the latch body and a crank opening formed in a second end of the latch body;
an over-center pivot disposed in the crank opening, the over-center pivot having a crank portion and ground portion, wherein the latch body pivots about the crank portion between a first latch position and second latch position, and wherein the crank portion rotates about the ground portion between a first crank position and a second crank position, the rotation of the crank portion about the ground portion to the second crank portion position allows the latch body to pivot about the crank portion to the second latch position;
a rack having a plurality of rack teeth spaced a distance apart, the distance between each of the plurality of rack teeth being sized to receive the latching tooth; and
a roller actuator assembly disposed at the first end of the latch body;
the roller actuator assembly having an extended position and a retracted position, wherein when the roller actuator is in the extended position the crank portion rotates from the first crank position to the second crank position.
