A seat device includes a seat cushion where a sitting person is seated, and a seatback configured to support the upper body of the sitting person. The seatback includes a seatback frame, a seatback pad placed on a front face of the seatback frame, and a seatback cover covering a surface of the seatback pad. A plurality of stretch airbags is provided in a part of the seatback at a position corresponding to the lumbar part of the sitting person, and the stretch airbags are configured to inflate and press a surface of the seatback to a direction approaching the sitting person. The stretch airbags are placed to overlap each other in a thickness direction of the seatback such that the seatback pad is sandwiched between the stretch airbags.

Seat device

A pneumatic pressure control method for a vehicle seat includes: repeatedly detecting an internal pressure of a bladder provided inside the vehicle seat at intervals; correcting the internal pressure of the bladder based on a differential pressure between a detection value and a target value; and lengthening a detection interval to detect the internal pressure depending on a time elapsing from starting of the vehicle.

Pneumatic pressure control method for vehicle seat and pneumatic pressure control device for vehicle seat

A vehicle seat device includes: a plurality of air bags configured to be provided inside a seat; a flow path having a shared section to communicate with each of the air bags; a plurality of intake valves each of which is arranged at a flow path position at an upstream of each of the air bags when air is pumped into each of the air bags; a plurality of exhaust valves arranged at flow path positions communicating with the shared section; and a control device configured to control operations of the intake valves and the exhaust valves, in which the control device adjusts a discharge speed of internal air by selectively opening the exhaust valves when the internal air of each of the air bags is discharged.

Vehicle seat device and intake and exhaust valve device

An air pressure control device of a vehicle seat includes: a bulging shape forming unit configured to form a bulging shape on a seat surface by expanding air bags configured to be provided inside a seat; a bulging shape moving unit configured to move a position of the bulging shape formed on the seat surface by each corresponding air bag by sequentially expanding and contracting a plurality of air bags aligned in a direction along the seat surface in an arrangement direction of the air bags; and a pumping capacity adjusting unit configured to increase a pumping capacity of an air pump that pumps air into each air bag as a protrusion amount of the corresponding bulging shape increases when a formation position of the bulging shape is moved.

Air pressure control device of vehicle seat and air pressure control method of vehicle seat

A seat apparatus for a vehicle includes a seating surface adjustment mechanism provided with an actuator and moving a seating surface of a vehicle seat in an up-down direction, a seat position adjustment mechanism for moving the vehicle seat in a vehicle front-rear direction, a seat position detection portion for detecting a front-rear direction position of the vehicle seat, a vehicle egress intention detection portion for detecting an intention of an occupant of the vehicle to get off the vehicle, and a drive control portion for performing a vehicle egress seating surface control in a case where the vehicle egress intention detection portion detects the intention of the occupant to get off the vehicle, the vehicle egress seating surface control controlling the seating surface adjustment mechanism so that the seating surface is positioned at a seating surface position set to correspond to the front-rear direction position of the seat.

Seat apparatus for vehicle

A vehicle seat device includes a lock mechanism, a drive source, which has an output portion, a cancellation detection portion, which detects the cancellation of restriction by the lock mechanism, and a restriction detection portion, which detects restriction by the lock mechanism. When cancelling restriction on the basis of operation of the operation switch, current is supplied to the drive source such that the output portion moves in the forward direction until the cancellation detection portion has detected cancellation, and when the cancellation has been detected, the supply of current to the drive source is stopped. When performing the restriction on the basis of operation of the operation switch, current is supplied to the drive source such that the output portion moves in the reverse direction until the restriction detection portion has detected restriction, and when restriction has been detected, the supply of current to the drive source is stopped.

Vehicle seat device

A control device for a vehicle seat is provided. This control device for the vehicle seat is provided with a control unit. In order to improve the performance of getting into and out of a vehicle, the control unit executes an away movement for moving the vehicle seat to the rear of the vehicle when a preset away condition is satisfied, and when a preset return condition is satisfied in this state, executes a return movement for moving the vehicle seat to the front of the vehicle. The return condition includes, as a first return condition, a vehicle door being closed with a portable key in the vehicle.

Control device for vehicle seat

A seat apparatus for a vehicle including a motor for operating a side support portion, includes, a sensor for detecting that the vehicle is driven on a curve, a distance between curves calculating program for calculating a distance between curves, and a control state determining program for determining a control state of the vehicle, the control state being set to one of an unexecuted state, an executed state and a standby state, wherein the motor operates the side support portion so as to be retained to a supporting position when the control state of the vehicle is set to the executed state.
