If the door is closed before the shoulder anchor reaches the
front end or if the door is opened before the anchor reaches
the rear end, the door lock switch turns from OPEN to
CLOSED or from CLOSED to OPEN. This alternately turns
relays L 1 and L2 ON and OFF, moving the shoulder anchor in
the corresponding direction. Time required for the shoulder
anchor to move from one end to the other is approximately
2 seconds.
Motor & Wire Protection Circuit
A circuit breaker and timer are used to protect the automatic
shoulder belt system circuit from damage.
If the shoulder anchor sticks for more than 13 seconds,
current flowing to the motor will be interrupted. However, it
can be corrected by opening and closing the door. If the motor
overloads, the circuit breaker activates immediately to inter-
rupt the current, protecting the motor against damage.
The circuit breaker automatically resets as soon the overload
is eliminated. Basically, the timer activates before the circuit
breaker does.
Rear Seat Belt
Two rear seat belts are installed. These seat belts are 2-point
hitch type and equipped with an ALR (Automatic Locking
L5-650
Retractor).
