POWER SEAT SYSTEM

id091300262000


Outline

•  The power seat system drives the electric motor, operates the front seats safely, and changes the driving posture to suit the occupant by operating the power seat switch.
•  10WAY power seats have been adopted on the driver's seat.
•  6WAY power seats have been adopted on the front passenger’s seat.

Function

•  The 10WAY power seats are equipped with the following functions:
―  Slide mechanism
―  Recliner mechanism
―  Lift mechanism
―  Tilt mechanism
―  Lumbar support mechanism
•  The 6WAY power seats are equipped with the following functions:
―  Slide mechanism
―  Recliner mechanism
―  Lift mechanism

Slide mechanism

•  The sliding function adjusts the front and back positions of the front seats.

Operation


Recliner operation (example: forward recline operation)

With position memory system
1.  When the recliner switch of the power seat switch is operated forward, the recliner switch on signal is input to the position memory control module.
2.  When the position memory control module receives the recliner switch on signal, power is supplied to the recliner motor and position sensor.
3.  When current flows to the recliner motor for forward motion, the motor drives to tilt the front seat back forward.

Without position memory system
1.  When the recliner switch is operated (1) forward, current from the battery flows (2) to the recliner motor.
2.  When current flows to the recliner motor for forward motion, the motor drives to tilt the front seat back forward.

Lift operation (example: lift up operation)

With position memory system
1.  When the lift switch of the power seat switch is operated up, the lift switch on signal is input to the position memory control module.
2.  When the position memory control module receives the lift switch on signal, power is supplied to the lift motor and position sensor.
3.  When current flows to the lift motor for lift-up motion, the motor drives to set the position of the front seat higher.

Without position memory system
1.  When the lift switch is operated (1) in the lift-up direction, current from the battery flows (2) to the lift motor.
2.  When current flows to the lift motor for lift-up motion, the motor drives to set the position of the front seat higher.

Slide operation (example: forward slide operation)

With position memory system
1.  When the slide switch of the power seat switch is operated forward, the slide switch on signal is input to the position memory control module.
2.  When the position memory control module receives the slide switch on signal, power is supplied to the slide motor and position sensor.
3.  When current flows to the slide motor and position sensor for forward motion, the motor drives to slide the front seat forward.

Tilt operation (example: tilt up operation)

With position memory system
1.  When the tilt switch of the power seat switch is operated up, the tilt switch on signal is input to the position memory control module.
2.  When the position memory control module receives the tilt switch on signal, power is supplied to the tilt motor and position sensor.
3.  When current flows to the tilt motor and position sensor for tilt-up motion, the motor drives to set the position of the front part of the front seat cushion higher.

Without position memory system
1.  When the tilt switch is operated (1) in the tilt-up direction, current from the battery flows (2) to the tilt motor.
2.  When current flows to the tilt motor for tilt-up motion, the motor drives to set the position of the front part of the front seat cushion higher.

Lumbar support operation (example: forward operation)

1.  When the lumbar support switch is operated (1) forward, current from the battery flows (2) to the lumbar support motor.
2.  When current flows to the lumbar support motor for forward motion, the motor drives to set the bulge amount of the lumbar area of the front seat back.
