  • Seat back recliner for vehicles
    Patent number: 6860560
    Abstract: A vehicle seat back recliner (24) includes a lock mechanism (50) having a locking pawl (52) for locking a seat back pivotal bracket (44) against pivoting with respect to a seat cushion stationary bracket (34) under the operation of an associated control cam (54) and a locking pawl catch (56). The catch (56) holds the locking pawl (52) in an unlocked position until the seat back is pivoted upwardly from a horizontal cargo position to an upright use position whereupon the catch releases the locking pawl and the control cam (54) maintains the locking pawl in its locked position. Pivoting of the control cam (54) against a spring bias provides release of the locking pawl (52) to permit seat back pivoting from a upright use position to the horizontal cargo position.
