A seat assembly for use in an automotive vehicle includes a seat back pivotally coupled to a seat cushion and at least one link pivotally coupled between the seat cushion and a seat base. A detent assembly is rotatably coupled to the seat base, the detent assembly actuatable between a use condition for operatively coupling the at least one link and the detent assembly, and an override condition for decoupling the at least one link and the detent assembly. A linkage motor is operatively engaged with the detent assembly for pivoting the at least one link to move the seat assembly between a plurality of positions. Actuation of the detent assembly from the use condition to the override condition allows for manual pivoting of the at least one link to move the seat assembly between the plurality of positions in situations where the linkage motor is unable to be actuated.

Seat assembly with override condition

A seat assembly secured to a floor in an automotive vehicle has a seat cushion, a seat back, a seat track assembly, a latch mechanism, a memory mechanism, and an interlock assembly. The seat back is operatively coupled to the seat cushion, and is movable between an upright position and a folded position. The seat track assembly includes a fixed track adapted to be fixedly secured to the floor and a movable track fixedly secured to the seat cushion. The movable track is slidably coupled to the fixed track. The latch mechanism is operatively coupled between the fixed and movable tracks. The latch mechanism prevents sliding movement of the movable track, and is () selectively unlocked from the fixed track to allow sliding movement of the seat cushion between a plurality of positions. The memory mechanism is operable between a home position and a memory position. In the home position, the memory mechanism is coupled and moves with the movable track. In the memory position, the memory mechanism is coupled with the fixed track and defines a previously selected one of the plurality of positions. The interlock assembly comprises a hook lever, an interlock lever, and a cable. The hook lever is pivotally connected to the seat cushion. The interlock lever is pivotally coupled to the movable track for movement between a disengaged position and an engaged position. The cable is operatively coupled between the hook lever and the interlock lever, and is configured for moving the hook lever into and out of engagement with the seat back. Moving the seat back to the folded position actuates the memory mechanism to the memory position, which unlocks the latch mechanism from the fixed track to allow sliding movement of the seat cushion in a first direction away from the previously selected one of the plurality of positions to the easy-entry position. Actuation of the memory mechanism to the memory position also allows the interlock lever to rotate into the engaged position to cause the cable to move the hook lever into engagement with the seat back to maintain the seat back in the folded position.

An interlock mechanism prevents erroneous operation of a vehicle rear seat. The vehicle seat has a seat back rotatably coupled to a seat cushion. The interlock mechanism includes a handle pivot link, a latch pivot link, and an interlock bracket rotatably coupled to a pivot pin. When the seat back is in an upright position, the interlock bracket releasably couples the handle pivot link to the latch pivot link such that rotation of the handle pivot link rotates the latch pivot link causing the cushion latches to be released. When the seat back is folded towards the seat cushion, the interlock bracket is moved to an interlock position decoupling the handle pivot link and the latch pivot link such that rotating the handle pivot link does not rotate the latch pivot link and does not release the cushion latches.

Handle interlock utilizing seat back rotation

A seat assembly for an automotive vehicle comprising a seat cushion and a seat back for pivotal movement between an upright seating position and a forwardly dumped position. A recliner mechanism is operatively coupled between the seat cushion and the seat back for selective actuation between a locked and unlocked condition allowing the pivotal movement of the seat back. A seat track assembly is coupled to the seat cushion for selective actuation between a locked and unlocked condition allowing fore and aft sliding movement of the seat assembly between a passenger comfort position and a full forward position. A recliner lockout mechanism is operatively coupled between the recliner mechanism and the seat back for selectively actuating the seat track assembly to the unlocked condition and provide movement of the seat assembly to the full forward position in response to pivotal movement of the seat back to the forwardly dumped position and retaining the seat back in the forward dumped position until the seat assembly is returned to a passenger comfort position and the seat track assembly is actuated to the locked condition.
