Abstract: Ratchet recliner for automotive vehicle seats provided with remote hand lever release feature. Lower bracket sandwich plate extensions for hand lever pivot and single plane push-pull connecting link accommodate integral assembled unit installation.

Abstract: Vehicle seat adjustable recliner hinge assembly employing toothed sector, pivoted toothed pawl and retractable pivoted eccentric cam resiliently urged to pawl engaging sector retaining seat backadjusted position, characterized by a remote lever actuated flexible cable release connection for said cam for applying cable tension at an effective cam actuating radial moment arm relative to the cam pivot in a direction opposite to the resilient biasing.

Abstract: An adjustable seat back hinge mechanism actuated by planetary gearing with means to provide an input/output reduction ratio within a range in the order of 30:1 to 50:1 from manual hand knob actuation or in the order of 120:1 for electric motor drive.

Abstract: Passenger car individual front passenger seat back actuated seat latch release means comprising pivotally connected seat and seat back bracket means, longitudinal track seat adjustment means including manual latch release means, pivoted lever means on the seat bracket means, striker means fixed on the seat back bracket means responsive to forward tilting for actuating the lever means, linkage means from the lever means for actuating said manual latch release means, the striker means including a surface for retaining the lever means in latch release mode during manual return of the seat to rearward position and seat back to upright position.

Abstract: A motor-vehicle seat hinge has an upper hinge element secured to the back part of the seat and a lower hinge element secured to the seat part, a positioning plate securable at any of a plurality of angularly offset positions and coacting with an abutment on the upper element to define the rest position for the seat back. An inertial two-arm pawl is pivoted on the upper hinge element and has on one arm a stop face which is engageable with the positioning plate in a blocking position of this pawl to prevent forward pivoting of the back seat. The other arm of the pawl is weighted so as normally to pivot from the blocking position into a freeing position when the back part is slowly pivoted forwardly but to resist due to its inertia the change of its position when the back part is subject to an abrupt forward movement.

Abstract: A vehicle seat back adjuster for achieving fine increments of adjustsment in the order of 1.degree., without resort to translation overdrive, through employment of reaction backup for teeth in the order of 1.degree. pitch in an adjustment quadrant minimizing yield of components which could permit fine tooth disengagement. .Iadd.An inertia latch per se serves as stop element for seating back rest position as well as arresting element preventing forward tilting under high vehicle deceleration for all positions of adjustment. .Iaddend.
