below the forward corner of the seat cushion. To adjust the angle of the seat
back, push up on the release button, position the seat back to the desired
angle and release the button. When the seat is not occupied, the seat back
will automatically fold forward whenever the release button is pushed up.
The six-way seats may be moved forward or aft, and are infinitely
adjustable for height and seat back angle. To position the seat, lift the
tubular handle under the center of the seat bottom, slide the seat into
position, release the handle, and check that the seat is locked in place.
Raise or lower the seat by rotating the large crank under the inboard corner
of either seat. The seat back is adjusted by rotating the small crank under
the outboard corner of either seat. The seat bottom angle will change as the
seat back angle changes, providing proper support. The seat backs will
also fold full forward.
The rear passengers' seat consists of a fixed one-piece seat bottom with
individually adjustable seat backs. The seat backs are adjusted by cylinder
lock release buttons, recessed into skirts located below the seat frame at
the outboard ends of the seat. To adjust a seat back, push up on the adjacent
cylinder lock release button, which is spring-loaded to the locked position,
recline the seat back to the desired position and release the button. When
the seat is not occupied, the seat backs will automatically fold forward
whenever the cylinder lock release button is pushed up.
Headrests are available for any of the seat configurations. To adjust
the headrest, apply enough pressure to it to raise or lower it to the desired
level. The headrest may be removed at any time by raising it until it
disengages from the top of the seat back.
SEAT BELTS AND SHOULDER HARNESSES
All seat positions are equipped with seat belts (see figure 7-4). The
pilot's and front passenger's seats are also equipped with separate
shoulder harnesses; separate shoulder harnesses are also available for the
rear seat positions. Integrated seat belt/ shoulder harnesses with inertia
reels can be furnished for the pilot's and front passenger's seat positions if
desired.
SEAT BELTS
The seat belts used with the pilot's and front passenger's seats, are
attached to fittings on the floorboard. The buckle half is inboard of each
seat and the link half is outboard of each seat. The belts for the rear seat are
attached to floorboard fittings and to the seat frame, with the link halves on
the left and right sides of the seat bottom, and the buckles at the center of the
seat bottom.

To use the seat belts for the front seats, position the seat as desired, and
then lengthen the link half of the belt as needed by grasping the sides of the
link and pulling against the belt. Insert and lock the belt link into the
buckle. Tighten the belt to a snug fit. Seat belts for the rear seat are used in
the same manner as the belts for the front seats. To release the seat belts,
grasp the top of the buckle opposite the link and pull upward.
SHOULDER HARNESSES
Each front seat shoulder harness is attached to a rear doorpost above
the window line and is stowed behind a stowage sheath above the cabin
door. To stow the harness, fold it and place it behind the sheath. When rear
seat shoulder harnesses are furnished, they are attached adjacent to the
lower corners of the aft side windows. Each rear seat harness is stowed
behind a stowage sheath above an aft side window.
To use a front or rear seat shoulder harness, fasten and adjust the seat
belt first. Lengthen the harness as required by pulling on the connecting
link on the end of the harness and the narrow release strap. Snap the
connecting link firmly onto the retaining stud on the seat belt link half.
Then adjust to length. A properly adjusted harness will permit the
occupant to lean forward enough to sit completely erect, but prevent
excessive forward movement and contact with objects during sudden
deceleration. Also, the pilot will want the freedom to reach all controls
easily.
Removing the shoulder harness is accomplished by pulling upward on
the narrow release strap, and removing the harness connecting link from
the stud on the seat belt link. In an emergency, the shoulder harness may be
removed by releasing the seat belt first and allowing the harness, still
attached to the link half of the seat belt, to drop to the side of the seat.
INTEGRATED SEAT BELT/SHOULDER HARNESSES WITH
INERTIA REELS
Integrated seat belt/ shoulder harnesses with inertia reels are availa-
ble for the pilot and front seat passenger. The seat belt/ shoulder harnesses
extend from inertia reels located in the cabin top structure, through slots in
the overhead console marked PILOT and COPILOT, to attach points
inboard of the two front seats. A separate seat belt half and buckle is
located outboard of the seats. Inertia reels allow complete freedom of body
movement. However, in the event of a sudden deceleration, they will lock
automatically to protect the occupants.
To use the seat belt/ shoulder harness, position the adjustable metal
link on the harness at about shoulder level, pull the link and harness
