RESTRAINT SYSTEMS
LAP
AND SHOULDER BELTS
The front seat belts incorporate a 4-to-8 second
fasten seat belt reminder lamp and sound signal
designed to remind the driver if the lap and shoulder
belts are not fastened when the ignition is turned to the
on position. If the driver's seat belt
is buckled, the
alarm will not operate; however, the fasten seat belt
xminder lamp will stay on for a 4-to-8 second period.
,, the driver's seat belt is not buckled, the reminder
lamp and sound signal will automatically shut off after
the 4-to-8 second interval. To diagnose a system
failure, refer to Seat Belt Reminder
Lamp/Alarm
Diagnosis in Section 8A.
The shoulder belt is attached to the front seat lap
belt latch plate and connected to an inertia locking
retractor installed to the roof panel above the right and
left side of the front seat. The shoulder belt remains
unlocked to allow the occupants to move freely while
the vehicle is being operated. When the vehicle
decelerates or changes direction abruptly, the shoulder
belt is locked in position by a pendulum that causes a
locking bar to engage a cog of the retractor mechanism.
The retractor has a comfort lock feature that
allows the occupant to adjust the shoulder belt for
proper fit and comfort. When engaged, the comfort
lock prevents full retraction of the webbing to eliminate
occupant discomfort due to webbing load on the
shoulder. The occupant can readjust the comfort lock
during vehicle operation as described below.
When servicing or replacing lap and shoulder
belts, refer to the following precautionary items: Front

CHILD SEAT
The child seat may be used only in a forward
facing seating location. When the child seat is used in
the front seat location, it is easily installed by
connecting the child seat top strap to the belt at the
seating position immediately to the rear (Fig. 11). The
outboard belt should be fully extended on the retractor.
Occupants should not be allowed to sit at locations
where the belts are being utilized for the child seat.
If a child seat is to be used, in
a second seat
position, a special dealer-installed anchor must be used
to anchor the child seat top strap. In order to assure
the correct top strap angle, the child seat is only to be
used at the seating position for which the top strap
anchor is installed. The following instructions explain
how to install the anchor for the child seat top strap.

(Pontiac) All styles have an inertia type front seatback as it could affect the performance of the seat
lock system. This system allows the seatback to move system.
freelv without reauiring the occupant to release a lock
leve; for access to the rear seat a;ea. During a sudden
stop, deceleration, or if the front of the car is declined
20 degrees or more, the seatback inertia locking system
locks the front seatbacks in an upright position. A
manual
seatback lock release lever is provided to allow
manual release of the inertia lock when the front of the
car is declined
20 degrees or more. The release lever is
located at the lower rear center of the seatback.
Front and rear seat cushions and backs have
formed foam pads, which
fit the contours of the full
panel
seatback frame assembly and also the designed
contour of the seat cushion frame.
There are no front seat dealer forward or
rearward relocation provisions provided at either seat
adjuster-to-floor pan attachments or seat
adjuster-to-seat frame attachments.

RECLINING SEATBACK
All styles have bucket seats with a tubular frame
design
seatback (Fig. 15) and a recliner control
mechanism. The tubular frame
seatback has a single
side, recliner control mechanism. This recliner
mechanism, which is mounted on the outboard side of
the seat, is the sole control of the
seatback angle. The
inner hinge arm attaching bolt acts only as a point of
rotation for the seatback. The inertia lock is an integral
part of the recliner control mechanism (Fig.
16).
To recline the seatback, rearward pressure must
be applied to the
seatback before lifting the recliner
release handle. When pressure is applied against the
seatback, the lockout lever tab disengages from the cam
plate tab. Then the release handle can be moved,
allowing the
seatback to move rearward. Releasing the
handle will allow the cam plate to move
counterclockwise and cause the sector lock teeth to
engage the upper hinge arm, locking the
seatback in the
desired reclined position. To return the
seatback to an
upright position, raise the recliner release handle.
