(3) When the ignition switch is turned from ON to OFF,
an H signal is output from timer I for 30 seconds,
but if the driver's side door is opened during this
time, the door switch turns ON. The input side of
NOT2 then becomes an L signal and the converted
H signal is input to the AND. It is matched with the
H signal from timer I and the output from the AND is
an H signal. This causes timer II to input an H signal
to OR2 for 30 seconds. This in turn causes Tr to
turn ON, and the front seat belt solenoid can
operate for a further 30 seconds.

SEAT BELT TENSION REDUCER TIMER
(1) Because an H signal is input to the OR1 when the
ignition switch is turned to ON, OR2 outputs an H
signal, and transistor Tr turns ON, enabling the front
seat belt solenoid (tension reducer function) to
operate. (For the tension reducer, refer to GROUP 6
- Seat Belt.)
(2) When the ignition switch is turned from ON to OFF,
the H signal converted by NOT1 causes timer I to
output an H signal for 30 seconds. Because the H
signal is input to OR 1, the front seat belt solenoid
can operate in the same way as in step (1). (30
seconds)
