ABSTRACT:
A manually operable seat adjustor assembly that combines the ease of operation of a long lever actuator, with the compactness of a short handle actuator. A handle assembly including an outer casing and an inner push rod movable within is pivoted to the side of the seat pan in common with a rear link of the seat supporting linkage. The tip of a locking rod passes through one of a series of positive detents, through a straight slot in the rear link, and through a clearance slot in the casing that has a straight portion alignable with the rear link straight slot. When the slots are so aligned, pushing on the push rod moves the locking rod tip out of the detent to free the linkage and into the aligned slots to rigidly hold the handle assembly to the rear link. Then, the linkage may be easily moved with the mechanical advantage of the entire handle, but when the handle is released, it pivots down freely under its own weight about the common pivot to an out of the way stored position alongside the seat pan.
