Seat belts, USA cars, models 1972—1973
Seat belts are provided for all seats in the car. The front
seat belts are of the three point type with an automatic
adjustment device, so called retractor for the lap belts.
The shoulder belts have to be adjusted manually. The
rear seats are provided with three lap belts. The two
Outer ones of the retractor type and the center belt with

It is Of greatest importance that the retractors and sliding
knots are correctly installed, otherwise the function of
the belts can be impaired.

Seat belts, model 1974
Reel belts with buckle lock in the front seat
The belt consists of a strap with one end secured at the
bottom. The free end runs through an eye up on the
door pillar and into the reel which, on 2-door cars, is
located inside of the rear side trim and on 4-door cars,
on the door pillar.
The belt is fastened by pulling the strap out and insert-
ing it directly into the buckle lock and dropping the
yoke, which locks automatically. The strap can run freely
through the buckle lock and the running eye and is there-
by automatically adjusted. The belt is released by press-
ing the key marked ‘‘press’’.
The reels have two locking mechanisms. One mechanism
is actuated by sudden acceleration of the reel (i.e. when
the strap is pulled out at high speed). The other is actuad-
ed by a pendulum which senses the movements of the car.
In the case of 4-door cars, there are two alternative
mounting points on the door pillars for the front seat
seat belts. For production reasons the belts are always
mounted in the upper hole.
The seat belt can be mounted in the lower mounting
point if so desired as a result of build, location of the
seat or the like.
Note that if the mounting point for a seat belt is changed,
the bolt should be tightened to a torque of 35-45 Nm
(26-33 ft.Ib., 3.5—4.5 kpm), and that a plastic plug
should be fitted in the upper hole.

HEATING AND VENTILATION SYSTEM
DIAGRAM OF HEATING AND VENTILATION SYSTEM, UP TO AND INCL. MODEL 1973
General, up to and incl. model 1973
Heating and ventilation are provided by a separate system
connected to the engine cooling system. Air enters through
the intake below the windshield to a collecting box formed
by the body sheeting, passing through a splash guard to the
fan heater core and on through the valve house into the
Passenger compartment. The fan and heater core are housed
in connected casings. Air passing through the heater core is
warmed by indirect heat exchange with circulating engine
coolant. The temperature can be varied with the thermostat-
controlled water valve; the sensitive element of the thermo-
stat is placed in the air stream to the passenger compart-
ment. Air from the heater core goes first to a valve house
where it is distributed to the front floor of the passenger
compartment by two flap valves. Branch pipes connected
to the valve house conduct air to the windshield and side
window defroster nozzles. szmur
CONTROLS AS FROM MODEL 1971
At the bottom of the valve house is a branching section
connected to the right and left rear channels, which con-
tain flap valves and controls for distribution of the air
supply to the back window defroster nozzles and the rear
of the passenger compartment. On top of the heater unit
are two separate fresh air takeoffs leading to swiveling
blower nozzles at either end of the instrument panel.
As from model 1971 there are fresh air take offs on the
instrument panel under the heating controls. The cold air,
that is taken in via a separate collector box placed beyond
the heat exchanger, is depending on the forced draught
generated when the car is driven and is not influenced by

The air passes into the fan casing through the air intake
in the dash panel.
As in previous models, the air is distributed by a flap
valve housing to the defroster nozzles and other outlets
in the coupé. A continuous moulded plastic channel
leads from the valve housing to the three fresh air out-
lets. The defroster nozzles to the rear window are locat-
ed in a raised defroster channel in the front edge of the
Parcel shelf. The nozzles are directed towards the middle
of the rear window so that the part of the window in the
line of sight from the rear-view mirror is the first to be
defrosted.
The controls for the heating and ventilation system are
essentially the same as on previous models. However,
the two outer fresh air outlet controls are different.
