Claim 11:
12. A locking assembly for a passive self-adjusting seat assembly, said seat assembly having a platform assembly engaging and electively movable relative to a guide assembly, said platform assembly including a support plate and said guide assembly including a guide plate positioned parallel to said support plate, said locking assembly comprising:
a cam bolt attached to said guide plate, said cam bolt having a shank and a cam member, said cam member positioned at an end of said shank, said shank having a bore formed into said end thereof, forming a shoulder at an end of said bore; said cam member having a cam surface, said cam surface defining an upper seat and a lower seat; and
an indexing rod having a first end of said indexing rod located within said bore of said cam bolt, a pin being attached to said first end, and a camming pin extending laterally from said indexing rod, said camming pin being in sliding contact with said cam surface of said cam bolt, wherein said first end comprises a threaded bore axially formed partially into said first end, wherein the pin is separate from the indexing rod, and wherein the pin is coupled to the engaging rod via a bolt that engages with the threaded bore;
wherein said indexing rod is rotatable between a locked position in which said camming pin is received within said lower seat of said cam surface and an unlocked position in which said camming pin is received within said upper seat of said cam surface, said camming pin being slidable along said cam surface between said lower seat and said upper seat of said cam surface, wherein sliding of said camming pin between said lower seat and said upper seat causes said pin to engage and disengage from said indexing aperture of said support plate.
