A gearbox for actuating at least one component of a vehicle seat. The gearbox includes a housing. An input pulley and an output pulley are rotatably coupled to the housing. A sun gear is attached to one of the pulleys. A ring gear is coupled to the housing and disposed about the sun gear. A plurality of planetary gears are attached to the other of the pulleys and are operably engaged with the sun gear and the ring gear. An input cable is coupled to the input pulley to rotate the input pulley in a first direction. An output cable is coupled to the output pulley and moves in a first direction in response to rotation of the input pulley. A biasing member is operatively connected to the output pulley to rotate the output pulley in a second direction opposite of the first direction to move the input cable.

Proposed is a recliner for a vehicle, the recliner including a mobile flange including a support portion having a multistage structure having stages with different outer diameters, an eccentric ring installed in a seating space of the mobile flange by being fitted with the support portion of the mobile flange, the eccentric ring including a corresponding end corresponding to the multistage structure of the support portion and formed on an inner surface being in contact with the support portion, a gear plate including an external gear configured to engage with the internal gear of the mobile flange, and a cam disposed between the eccentric ring and the gear plate and configured to press the gear plate to one side.

A seat system for a vehicle may have a seat base assembly and a seat back assembly. Each of the seat base assembly and the seat back assembly may include at least one actuator assembly at least partially disposed therein. The actuator assembly may be configured to selectively adjust at least one of the seat base assembly and the seat back assembly to reach a desired angle, position, and/or height. The actuator assembly may include a motor assembly and a gear assembly, wherein the motor assembly includes a printed circuit board stator.

A seat adjustment mechanism includes a first component and a second component movable relative to the first component. A drive mechanism is drivingly connected to the second component for moving the second component relative to the first component. The drive mechanism includes a drive motor drivingly connected to a first gear member having conical involute teeth. A second gear member includes conical involute teeth in meshing engagement with the conical involute teeth of the first gear member. The conical involute teeth have a tapered tooth thickness, a tapered root and a tapered outside diameter.

A power recliner drive for a vehicle seat includes a motor having an output shaft and a worm gear. A helical gear is meshingly engaged with the worm gear, the helical gear having an eccentric hub extending therefrom. A locking fork includes a guide slot movably received on a guide pin and a fork end having a pair of legs that straddle the eccentric hub of the helical gear, the pair of legs each including a drive slot. A planetary gear includes a pair of lugs each engaging a respective one of the drive slots of the pair of legs and including a first plurality of external gear teeth. An output gear includes a second plurality of internal gear teeth meshingly engaged by the first plurality of external gear teeth of the planetary gear, the output gear being configured to be connected to a shaft of a reclining seat back.
