DESCRIPTION AND OPERATION 76-5-5
Seat switch pack
Each seat switch pack contains two switches representing the seat cushion and the seat squab. The switches provide
the following adjustments:
lSeat fore/ aft.
lCushion front up/ down.
lCushion rear up/ down.
lSquab fore/ aft.
lLumbar inflate.
lLumbar deflate.
The voltage supply to the seat switch pack is from the 40A fuse in the satellite fuse box. A pair of switches controls
the operation of each seat motor, the lumbar pump and the lumbar deflate relay.
Seat fore/ aft motor
The seat fore/ aft motor is a permanent magnet motor coupled to a rack and pinion assembly. Should the motor seize
or stick for 6 seconds or more, an internal thermal cut out switch will trip to remove voltage from the motor. Reset
time for the switch is 35 seconds.

76-5-6 DESCRIPTION AND OPERATION
Two pins within the seat switch pack control the seat fore/ aft motor. Both pins are normally earthed. Operating the
backward switch applies voltage to that pin while the other pin remains earthed. Operating the forward switch reverses
power and earth to the motor allowing the motor to run in the opposite direction.
Seat cushion front up/ down motor
The seat cushion front up/ down motor is a permanent magnet motor coupled to a rack and pinion assembly. Should
the motor seize or stick for 6 seconds or more an internal thermal cut out switch will trip to remove voltage from the
motor. Reset time for the switch is 35 seconds.
Two pins within the seat switch pack control the seat cushion front up/ down motor. Both pins are normally earthed.
Operating the up switch applies voltage to that pin while the other pin remains earthed. Operating the down switch
reverses power and earth to the motor allowing the motor to run in the opposite direction.
Seat cushion rear up/ down motor
The seat cushion rear up/ down motor is a permanent magnet motor coupled to a rack and pinion assembly. Should
the motor seize or stick for 6 seconds or more, an internal thermal cut out switch will trip to remove voltage from the
motor. Reset time for the switch is 35 seconds.
Two pins within the seat switch pack control the seat cushion rear up/ down motor. Both pins are normally earthed.
Operating the up switch applies voltage to that pin while the other pin remains earthed. Operating the down switch
reverses power and earth to the motor allowing the motor to run in the opposite direction.
Seat squab fore/ aft motor
The squab fore/ aft motor is a permanent magnet motor coupled to a rotary rack and pinion assembly. Should the
motor seize or stick for 6 seconds or more, an internal thermal cut out switch will trip to remove voltage from the motor.
Reset time for the switch is 35 seconds.
Two pins within the seat switch pack control the squab fore/ aft motor. Both pins are normally earthed. Operating the
fore switch applies voltage to that pin while the other pin remains earthed. Operating the aft switch reverses power
and earth to the motor allowing the motor to run in the opposite direction.
Lumbar pump
The lumbar pump inflates a bladder in the squab which provides extra support for the seat occupant. With no load on
the seat it takes approximately 10 seconds to completely inflate the bladder. With a load of 25 kg (55 lb) it takes
approximately 15 seconds to inflate the bladder. A pressure cut off switch in the system will operate at 0.12 to 1.93
bar (1.8 to 28 lbf.in
2). If a problem occurs with the lumbar bladder, e.g. a rupture, the whole lumbar system must be
replaced. The components are not serviceable.
Power comes from the seat switch pack through a 3A fuse in the satellite fuse box. The lumbar pump and the lumbar
deflate solenoid share an earth.
Lumbar deflate solenoid
The lumbar deflate solenoid vents the lumbar bladder to atmosphere to allow air to evacuate the bladder. The average
time to evacuate the bladder with a load of 25 kg (55 lb) is 9 seconds.
Power comes from the seat switch pack through a 3A fuse in the satellite fuse box. The lumbar deflate solenoid and
the lumbar pump share an earth.
