Abstract

Three mechanical locks are part of a mechanism for adjusting and dumping a vehicle seat. A master mechanical lock attaches to the seat back. When it is unlocked, depending on the condition of the other locks, one can adjust or dump the seat. A dumping mechanical lock also attaches to the seat back through an intermediary of a slave mechanical lock. When the dumping mechanical lock is unlocked, a connection to the master mechanical lock also opens that lock to allow the seat back to dump. When one unlocks just the master mechanical lock, a connection between that lock and the slave lock unlocks the slave lock. When that lock is unlocked, one can adjust the distance of dumping mechanical lock to the seat back. Because the slave lock remains locked during dumping, the distance between the dumping mechanical lock and the seat back remains constant after dumping. A latch mechanism keeps the dumping lock unlocked until the dumping lock returns to a predetermined position. A connection between the master and dumping locks keeps the master lock unlocked as long as the latch mechanism keeps the dumping lock unlocked.
