PART 5: SEAT AND RESTRAINT SYSTEMS
cause of relative movement between the seat and the
cab.
3. Check the Komfort Latch for cracks or possible damage
and that it works properly.
4. Check the buckle and latch for proper operation and
to determine if the latch plate is worn, deformed, or
damaged.
5. Inspect the retractor web storage device, that is
mounted on the floor or B-pillar of the vehicle for
damage. The retractor is the hear t of the occupant
restraint system and can often be damaged if abused,
even unintentionally. Check retractor web storage
device operation to ensure that it is not locked up and
that it spools out and retracts webbing properly.
WARNING! Failure to adjust tether belts properly
can cause excessive movement of the
seat in an accident. This could lead to greater
injuries for you. Tether belts should be adjusted
so that they are taut when the seat is
in its most upward and forward position.
6. If adjustable tethers are being used, be sure they are
adjusted in accordance with installation instructions.
Tethers must also be inspected for web wear, just as
with the seat belt systems.
Inspection of the Restraint System
7. Mounting hardware should be evaluated for corrosion,
and for tightness of bolts and nuts.
8. Check web in areas exposed to ultraviolet rays from
the sun. If the color of the web in these areas is gray to
light brown, the physical strength of this web may have
deteriorated due to exposure to the sun’s ultraviolet
rays; replace the system.
WARNING! Replace the entire belt system (retractor
and buckle side) if replacement of any
one part is necessary. Unexposed damage to
one or more components could prevent the system
from functioning properly the next time it is
needed, which could result in severe injury or
even death.
If the inspection indicates that any part of the seat belt
system requires replacement, the entire system must be
replaced, both retractor and buckle side. An installation
guide is attached to every replacement belt. This set of instructions
is entitled “THREE-POINT SEAT BELT INSTAL-
LATION GUIDE.” There are separate seat belt instruction
guides for suspension and fixed bench seats. Use the
proper guide for your type of seat, and follow the instructions
very closely. It is vitally important that all components
must be remounted back in the same position as the origi-
