Easy entry seat track assembly with full memory

Abstract

An easy entry seat track assembly with full memory comprises a lower track assembly and an upper track assembly, releasably slidable on the lower track assembly. A master latch assembly in a latching position releasably secures the upper track assembly to the lower track assembly at an initial position. A rod is affixed to the lower track assembly, preferably on a lower track, and a memory register comprising a wrap spring is positioned around the rod. A memory actuation mechanism moves the memory register from a normal condition to a memory position and disengages the master latch, allowing the upper track assembly to slide over the lower track assembly to a free position. Return of the upper track assembly to the initial position returns the master latch to reengage the lower track assembly, and then returns the memory register to the normal condition. The memory actuation mechanism can comprise a cam lever rotatable from a first position where the memory register is in the normal condition, to an operating position where the memory register is in the memory position and the cam lever urges the master latch into the unlatching position. The memory register stays in the memory position and the master latch stays in the unlatching position until the upper track assembly returns from the free position to the initial position. A latch mechanism such as a latch plate or latch-lock lever may be used to hold the cam lever in the operating position while the upper track is in a free position.
