but prevent excessive forward movement and contact with objects dur-
ing 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.

Integra.ted seat belt/shoulder harnesses with inertia reels are avail-
able for the pilot and front seat passenger. The seat belt/shoulder har-
nesses extend from inertia reels located in the cabin ceiling to attach
points inboard of the two front seats. A selnrate 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.
NOTE
The inertia reels are located for maximum shoulder har-
ness comfort and safe retention of the seat occupants.
This location requires that the shoulder harnesses cross
near the top so that the right hand inertia reel serves the
pilot and the left hand reel serves the front passenger.
When fastening the harness, check to ensure the proper
harness is being used.
To use the seat belt/shoulder harness, position the adjustable metal
link on the harness just below shoulder level, pull the link and harness
downward, and insert the link into the seat belt buckle. Adjust belt ten-
sion across the lap by pulting upward on the shoulder harness. Removal
is accomplished by releasing the seat belt buckle, which will allow the
inertia reel to puII the harness inboard of the seat.
