A lift mechanism for a vehicle seating assembly comprises a gear assembly that includes a first gear and a second gear. A mounting bracket is fixedly coupled to a vehicle and shares a common axis with the first gear, wherein the first and second gears are positionable in a fixedly coupled arrangement at an initial location relative to the mounting bracket or at a final location relative to the mounting bracket, such that, when the first and second gears are in the fixedly coupled arrangement at the initial location relative to the mounting bracket, the seating assembly is in a sitting position, and when the first and second gears are in the fixedly coupled arrangement at the final location relative to the mounting bracket, the seating assembly is in a standing position.

Disclosed herein is a vehicle seat recliner. A center boss of an external gear includes a first end and a second end having a larger diameter than the first end. Since the load of the center boss is easily distributed, it is possible to secure smooth operation performance by preventing the deformation of the center boss even though a strong external force is applied to the recliner. Since there is no need to perform heat treatment on the center boss for securing the strength thereof, manufacturing costs are reduced.

A recliner heart may include a first locking plate, a second locking plate, a cam and a lubricant member. The first locking plate includes an outer diametrical surface having first teeth formed thereon. The second locking plate is rotatable relative to the first locking plate and includes an inner diametrical surface having second teeth formed thereon. Some of the second teeth are meshingly engaged with some of the first teeth. The cam is connected to the second locking plate and includes a groove formed therein. The lubricant member is disposed in the groove of the cam.

A vehicle seating assembly has a seat, a seatback and a bracket extending between the seat and the seatback with a first pivotable coupling between the bracket and the seat, a second pivotable coupling between the bracket and the seatback, and a sector gear portion with a gear assembly including a spur gear. The sector gear portion is disposed along an edge of the bracket, wherein the spur gear is rotatable to engage the sector gear portion of the bracket to move the bracket from a first position to a second position to move the second pivotable coupling from a primary position to a secondary position.

A vehicle seating assembly includes a seat including a side bracket, a seatback, a displaceable bracket extending between the seatback and the side bracket, a pivotable seatback coupling between the displaceable bracket and the seatback, and a movement assembly operably coupling the displaceable bracket to the side bracket. The movement assembly is positionable between a design position and a fully deployed position to move the displaceable bracket between a first position and a second position, respectively, and to move the pivotable seatback coupling between a primary positon and a secondary position, respectively, wherein, when the pivotable seatback coupling is in a secondary position, the seatback is movable between a forward inclined position and a substantially flat position.

A vehicle seat comprising a seatback mounted pivoting by an articulation mechanism selectively lockable and unlockable, relative to a seatback footing selectively lockable and unlockable on a base, where the seat further comprises a seat cushion, first and second rear connecting rods connecting the seatback to the base, an actuating device being configured, by rotation of the first rear connecting rod, for driving the seatback into a folded down position when the articulation mechanism is unlocked and the seatback footing is locked on the base, and for driving the seat in a forward tilted position when the seatback footing is unlocked and the articulation mechanism is locked.

A recliner heart may include a first locking plate, a second locking plate, a cam and a lubricant member. The first locking plate includes an outer diametrical surface having first teeth formed thereon. The second locking plate is rotatable relative to the first locking plate and includes an inner diametrical surface having second teeth formed thereon. Some of the second teeth are meshingly engaged with some of the first teeth. The cam is connected to the second locking plate and includes a groove formed therein. The lubricant member is disposed in the groove of the cam.

An adjustment mechanism for a vehicle seat includes an actuator and a driven member. The actuator is coupled to the driven member to cause the driven member to move or be freed to move in response to activating the actuator.

A vehicle seat actuator includes an electric motor and a gear set that connects the drive motor to the seat and transmits the output of the motor to the vehicle seat. The drive motor and gear set are each disposed in an individual, dedicated housing component. The individual housing components are then assembled together to provide the actuator. The housing components are maintained in the assembled configuration using snap fit mechanical fasteners. Each snap-fit fastener includes a receiving portion provided on one housing component and a retaining portion provided on the other housing component. The receiving portion may be a blind hole formed in the drive motor housing that is partially obstructed by an elastic member, while the retaining component is a latch that protrudes from an outer surface of the gear housing and forms a snap-fit engagement with the elastic member.

A rail for vehicle seat that has first and second sliding rail members driven by a motorized drive mechanism. The rail further includes a mechanical latch actuated when crash conditions are detected.
