CONSTRUCTION AND OPERATION OF THE OUTER
SWITCH
Gear B
The outer switch is installed at the retractor for the shoulder
belt.
The component is an assembly supply item, and so is not to be
disassembled. Its construction and operation are, however, as
described below.
Gear A rotates in unison with the shaft of the retractor; gear C's
speed is reduced by way of gear B, thus resulting in rotation.
A cam is installed to gear C. In the illustration, the belt is at the
fully rewound position; contacts A and B are separated, and the
switch is switched OFF.
When the belt is pulled out about 750 mm (29.5 in.), the cam
presses contact A, with the result that contacts A and B
contact, and the switch is switched ON.
The switch is ON until the completely pulled-out position is
reached.
At the time of rewind, the cam is caused to rotate in the
direction opposite to the direction during pull-out, and the
switch is switched from ON to OFF when the belt reaches the
approximately 750 mm (29.5 in.) pulled-out position.
If the sequence switch is turned OFF, the warning light comes
on.
CONSTRUCTION AND OPERATION OF THE ENERGY-
ABSORBING BELT AND THE BUCKLE
The driver's seat belt has on -it a sleeve inside which the seat
belt webbing is folded back over itself in a loop so as to absorb
the energy of a shock by pulling loose and releasing slack.
There is a spring installed in the portion connecting the buckle
to the arm, allowing the buckle to tilt forward and inward so
that the belts can be tight enough around the body.
