Abstract: An embodiment position locking apparatus includes a track tube, convex-curved serrations in the track tube, a radial pawl, a pin, concave-curved serrations in the radial pawl, and a motion-translation component. The radial pawl may have a pivot point and the pin extending from the radial pawl. The motion-translation component may have a slot formed therein and disposed adjacent the radial pawl. The pin may extend into the slot so the slot at least partially constrains motion of the pin such that a pivotal motion of the motion-translation component is translated to a slider motion of the pin to control a rate of angular motion of the radial pawl pivoting about the pivot point and so the concave-curved serrations engage and disengage with the convex-curved serrations to lock and unlock a position of the track tube relative to the radial pawl.
