Since the rear clutch and the kickdown brake are actuated when theshift is in
2nd gear in the “0” or the “2” range, driving force is
transmitted to the forward sun gear which rotates in the clockwise
direction,
Therefore, torque is conveyed from the forward sun gear through the
short and long pinions to the annulus gear, as in the case of 1 st gear.
--However, since the reverse sun gear is fastened by in the case of
2ndgear, the long pinion“walks” on the reverse sun gear in the direction
of arrow (A), causing the annulus gear to rotate faster (or more) than
in the case of 1 st
gear in proportion to the length that the long pinionhas “walked”.
The reduction ratio of
2nd gear is achieved in this way.

IWhen the shift is in

reverse sun gear because the front clutch is actuated.-1
And the low reverse brake is also actuated, fastening the planetan/
gear set carrier. This means that the driving force is conveyed from
the reverse sun gear (clockwise) through the long pinion (counter-
clockwise) to the
annulus gear (counterclockwise).*

Since the carrier is fastened at this time, the long pinion’s
fixed, causing the long pinion to function as an idler gear. The
counterclockwise rotation and reduction ratio of back gear are
obtained in this way.

23-32BODY - Seat Belts
OPERATION OF AUTOMATIC SEAT BELTS
The operation of the Automatic Seat Belts is as follows.
(1) The belts fasten itself around the occupant when the front
door is closed with the ignition switch in the “ON” position.
(2) The belts release itself from the occupant when the front
door is opened with the ignition switch in the
*“ON” or
“LOCK” or “ACC” position.
(3) The belts cease to fasten itself around the occupant if the
ignition switch is turned to “LOCK” or “ACC” or when the
front door is opened during the belt motion.
(4) The belts for the driver’s and front passenger’s seats
operate independently of each other.

ELR/ALR,
SWITCHOVER MECHANISM
The
ELR/ALR switchover mechanism is installed at the re
tor for the lap belt for the front passenger’s seat,
The component is an assembly supply item, and so is not to be
disassembled. Its construction and operation are, however, as
described below.
Gear
B is coupled with the shaft of the retractor; it rotates in ::the counterclockwise direction when the belt is pulled out.
Gear A is meshed with gear
B, and revolve in the same
direction as gear
B.The illustration
(19PO373) shows the condition when the belt is
completely rewound.
When the belt is pulled out completely, gear A revolves about
three times, and the gear A cam contacts rod A, thereby
pressing rod A. Rod A then presses the stopper, and the
stopper presses the sub
pawl.When the sub pawl is pressed, the internal lock mechanism
functions, and the belt pull-out motion becomes lock, thus
becoming ALR.
When the belt
is rewound about 600 mm (23.6 in.) from the
completely pulled-out position, gear A revolves in the clockwise
direction. with the result that the cam of gear A contacts rod
6and causes rod
B to be pressed.
Rod
B then presses the stopper, thus causing the sub pan -return. thereby unlocking the lock and making pull-out
freti.thus becoming ELR.

are wound to drum A.Drum

There are projections on gear

gear
B projection contacts the drum B projection
only when gear
