Abstract:
1. A vehicle seat rear floor latch and seat back positioner assembly comprising: a housing for connection to a vehicle seat bottom and including a pair of spaced plates; a latch pivotally mounted between the pair of space plates of the housing for movement between a latched position for securing the housing to a vehicle floor and an unlatched position for releasing the housing from the vehicle floor; a seat back connector lever for connection to a vehicle seat back and pivotally mounted between the pair of spaced plates of the housing for movement between a generally upright seating position and a generally horizontal nonuse position; a locking cam pivotally mounted between the spaced plates of the housing and having a blocking position for holding the seat back connector lever in its generally upright seating position, and the locking cam having a released position where the seat back connector lever is free to move from its generally upright seating position to its generally horizontal nonuse position; a latch cam mechanism including a friction cam and a structural cam pivotally mounted about a common axis between the spaced plates of the housing, the friction cam having a blocking position for contacting the latch with an inclined pressure angle that holds the latch in its latched position, the friction cam being movable to a released position to release the latch for movement to its unlatched position, the structural cam having a blocking position for facing the latch in a spaced relationship to hold the latch in its latched position upon loading of the latch mechanism above a load limit of the friction cam with the inclined pressure angle, and the structural cam having a released position where the latch is free to move from the its latched position to its released position; an interlock link pivotally mounted on the housing between the pair of spaced plates of the housing and having first and second ends for respectively contacting the seat back connector lever and the latch cam mechanism to prevent movement of the friction cam and the structural cam from their respective blocking positions to their respective released positions when the seat back connector lever is in its generally upright seating position, and the first and second ends of the interlock lever allowing the friction cam and structural cam to move from their respective blocking positions to their respective released positions when the seat back connector lever is in its nonuse position and the latch then being movable from its latched position to its unlatched position to release the housing from the vehicle floor; a release member pivotally mounted on the housing between the spaced plates of the housing for pivotal movement for moving the latch cam mechanism so its friction cam and its structural cam are moved from their respective blocking positions to their respective released positions; an actuating member pivotally mounted on the housing between the spaced plates of the housing for pivotal movement from an idle position to a first released position that moves the locking cam from its blocking position to its released position so the seat back connector lever is movable from its generally upright seating position to its generally horizontal nonuse position, and continued pivotal movement of the actuating member from its first released position to a second released position pivotally moving the release member to move the latch cam mechanism so its friction cam and its structural cam are moved from their respective blocking positions to their respective released positions to allow the latch to move from its latched position to its unlatched position and release the housing from the vehicle floor; and the latch cam mechanism having a connector for moving its friction cam and its structural cam from their respective blocking positions to their respective released positions independently of any movement of the actuating member from it first released position to its second released position.
