POWER SEAT SYSTEM

id091300703300


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.

Function

•  The 10WAY power seat has been adopted for the driver's seat.
•  The 10WAY power seats are equipped with the following functions:
―  Slide mechanism
―  Recliner mechanism
―  Lift mechanism
―  Tilt mechanism
―  Lumbar support mechanism
―  Power walk in mechanism

Slide mechanism

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

Recliner mechanism

•  The recliner function adjusts the angle of the front seat backs.

Power walk in mechanism

Note
•  The driver’s seat operates using the walk in switch only while there is no passenger on the driver’s seat.
•  The angle of the front seat backs can be adjusted forward and rearward by operating the walk in switch (recliner switch).
•  The front seats can be adjusted forward and rearward by operating the walk in switch (slide switch). This allows occupants easy access to the rear seat.

Operation


Operation conditions

•  Not applicable


Recliner operation (example: forward recline operation)

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.
3.  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)

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.
3.  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)

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.
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)

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.
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

Lumbar support operation (example: forward operation)

1.  When the power seat 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.

Power walk in operation (example: sliding forward operation)

Note
•  The driver’s seat operates using the walk in switch only while there is no passenger on the driver’s seat.
1.  When the walk in switch (slide switch) is operated, the walk in switch ON signal is input to the position memory control module.
2.  When the position memory control module receives the slide switch ON signal, it sends a motor operation signal to the slide motor and position sensor.
3.  When the slide motor and position sensor receives the motor operation signal, the motor is driven to slide the front seat forward.

Power walk in operation (example: forward recline operation)

Note
•  The driver’s seat operates using the walk in switch only while there is no passenger on the driver’s seat.
1.  When the walk in switch (recliner switch) is operated, the walk in switch ON signal is input to the position memory control module.
2.  When the position memory control module receives the recliner switch ON signal, it sends a motor operation signal to the recliner motor and position sensor.
3.  When the recliner motor and position sensor receives the motor operation signal, the motor is driven to tilt the front seat back forward.
