The present disclosure relates to a power seat integrated control method. One embodiment of the present disclosure includes: a signal input step of receiving a power seat operation signal input that a user inputs through an interface of a vehicle; a determination step of determining an operating condition for operating a motor module that is built into the power seat and moves a specific area of the power seat; and an information transmission step of transmitting driving information for controlling the motor module in accordance with a type of the operation signal. The motor module includes a driving motor and a motor controller which controls the driving motor, and one LIN communication bus is provided between the integrated controller and each power seat. In the information transmission step, the integrated controller transmits the driving information to the motor controller through the LIN communication bus.

The present disclosure relates to a vehicle seat rail. The vehicle seat rail includes a lower rail fixed to a bottom of a vehicle, an upper rail fixed to a seat at an upper portion thereof and coupled to the lower rail to be slidably movable, a restoring spring fixedly coupled to the lower rail at one end thereof in a longitudinal direction and configured to provide a restoring force to the upper rail, and a connection bracket configured to connect the restoring spring to the upper rail. The lower rail may accommodate the restoring spring and the connection bracket to implement a walk-in function even when the lower rail is buried in the floor.

The present disclosure relates to the brake device of the power swivel seat that ensures to have no clearance in the rotational direction during operation of the swivel seat, resulting in improved stability of the operation, and minimized generation of operating noise. Disclosed is a brake device of a power swivel seat including: a brake ring connected to a swivel fixing part; a brake wedge connected to a swivel rotating part; a brake roller and a brake spring installed in a wedge space formed between an inner circumferential surface of the brake ring and an outer circumferential surface of the brake wedge; and an unlocking block installed to rotate the brake wedge in a direction allowing to release lock caused by the brake roller in the wedge space.

The present disclosure relates to a track lever assembly structure of a seat, which is capable of preventing in advance a lock release phenomenon due to a problem that a rear seat passenger's foot is caught by causing an assembly position between a track lever and a locking assembly to be set within the seat rail, and of changing an assembly structure for interlocking operation between the track lever and the locking assembly into a fastening structure having an interlocking operation method using a holder hinge-coupled to the inside of a moving rail, thereby minimizing the number and weight of related parts and simplifying an assembly process.

The present disclosure relates to an armrest tilting device provided on a seat and capable of tilting and adjusting an armrest capable of supporting a user's arm. The armrest tilting device includes: a shaft which is installed on a seat and has one end installed on an armrest in such a way as to be relatively rotated; a housing which is fastened to the armrest and supports the shaft in the state where the shaft is installed on the armrest; a bracket which is fastened and fixed to the shaft; a ratchet which is rotatably fastened to a hinge member fastened to the bracket; a sector gear portion which is fastened to and rotates together with the armrest and is engaged with the ratchet; a guide plate which is provided on the sector gear portion and where the ratchet moves in one area while being separated from the sector gear portion; and an elastic member which applies an elastic force such that ratchet gear teeth formed on the ratchet are meshed with sector gear teeth formed on the sector gear portion.

Disclosed herein is a controller-integrated driving motor module. The controller-integrated driving motor module includes: a motor; a motor housing configured such that the motor is accommodated therein; a power transmission unit connected to the motor, and configured to transmit a rotational force of the motor to each part of a power seat for the movement of the power seat disposed in a vehicle; and a controller disposed between the motor and the power transmission unit, and configured to control the rotation of the motor. The controller includes a MCU configured to control the rotation of the motor, an inverter configured to receive a driving signal from the controller and drive the motor, and a power supply unit configured to receive power from the battery of the vehicle and provide the power to the controller.

A height adjustment device and a swivel device for a vehicle seat are configured to adjust seat height and swivel the vehicle seat. The height adjustment device includes a first reduction gear device disposed at a bottom of the vehicle seat and configured to increase output torque of a first motor and a lifting device engaged with the first reduction gear device and configured to move the seat upwards or downwards, and the swivel device includes a motor driving unit disposed at a bottom of the height adjustment device and a second reduction gear device configured to increase output torque of the motor driving unit, thereby making it possible not only to selectively perform seat height adjustment and swivel operation, but also to perform a monopost function of the seat in a state in which the height adjustment device and the swivel device are stacked in a vertical direction.

A power swivel device for a vehicle seat is configured to perform both swivel and monopost functions of the vehicle seat. The power swivel device includes a motor configured to swivel the seat and a reduction gear device configured to increase output torque of the motor, which are stacked in a vertical direction on a bottom of the seat. The power swivel device includes a lower housing; an upper housing stacked on and assembled to the lower housing; an eccentric shaft rotatably disposed relative to the lower housing and the upper housing; a motor driving unit mounted between the lower housing and the eccentric shaft; the reduction gear device installed between the upper housing and the eccentric shaft; and a swivel plate rotatably mounted on the reduction gear device and connected to a seat cushion frame.

A walk-in apparatus for a vehicle seat includes a walk-in bracket rotatably coupled to a crossbar of a cushion frame and operable to release a fixing member by contacting the fixing member of a seat rail; a compensator bracket operably connected to the walk-in bracket through a hinge, the compensator bracket also being connected to a walk-in cable; and a compensator spring configured to support the walk-in bracket and the compensator bracket, rotate at least one of the walk-in bracket and the compensator bracket, and operate in such a manner as to return the compensator bracket. Even when the walk-in cable is released due to a seatback rebound phenomenon during a walk-in operation, the walk-in bracket maintains a pressing state of the fixing member to maintain continuously an unlocking state of the seat rail, allowing the vehicle seat to move forward smoothly to enable a walk-in operation.

A device for height adjustment and swivel of a seat for a vehicle has a structure in which a first motor for height adjustment of the seat, a first reduction gear device for increasing output torque of the first motor, and a lifting device configured to lift or lower the seat by being connected to the first reduction gear device are stacked in a vertical direction, and a second motor for driving of seat swivel, a second reduction gear device for increasing output torque of the second motor, a brake device configured to stop the seat are vertically stacked between a bottom of the seat and the first motor, in order to adjust the height of the seat, enable accurate swiveling, and carry out a monopost function of the seat.
