each belt strap.
2.38.1.5 Harness Lock Control Lever. The barness
lock control lever on the left side of the seat bucket
has two detented positions. In the forward (locked) position,
forward movement of the occupant is restricted
and any slack created by rearward movement is taken
up by the inertial reel. The control is locked in this
position by a detent. In the aft position, the occupant can
move forward freely, unless the reel locks owing to
excessive forward velocity. When the forward velocity
decreases suft%iently, the inertia straps are released
without the necessity of repositioning the manual control.
Both straps feed from the same shaft, and it is
impossible for one to lock without the other. If the reel
is locked manually the control must be positioned aft to
the unlocked position to release the straps.
2.38.1.8 Leg Restraints. Theleggartersandrestmint
cords keep the occupant’s leg firmly against the leg rests
during ejection. The garters are placed around the leg
below the calf and above the knee.
The leg-restraint cords are attached to the aircraft
deck and routed through the seat snubber box structure.
They are then passed through garter rings and snapped
into the leg-line locks. The garterr ings are snappedin to
the bayonet fitting when strapping in. Leg-line release
is accomplished by pulling the manual override handle.
Leg restraints may be adjusted by pulling the tab on the
inner side of each leg-line snubber box.
2.38.1.7 Negative-G Strap. The negative-g strap is
not incorporated in the F-14D NACES ejection seat
2.38.1.8 Seat Height Adjustment Switch. Seat

1 IS-Vat electric motor. Operation of the actuator is controlled
by a three-position switch on the right aft side of
the seat bucket marked RAISE, OFF, and LOWER. The
switch is spring loaded to the center OFF position;
RAISE is aft and LOWER is forward. Electric power is
supplied from phase B of the right main ac bus through
the ACM LT/SEAT ADJ/STEADY POS LT circuit
breaker (214).
The seat height actuator motor has a maximum
duty cycle of 1 minute on in any
8-minute period.
2.38.1.9 Survival Kit. The survival kit (Figure 2-127)
forma the sitting platform for the crewmember and consists
of a fabric survival-aids container covered by a
contoured, rigid platform with a cushion on top to provide
a firm seat and additional comfort for the crewmember.
The kit is retained in position by pivot fittings
at the front and lugs attachedt o the lower harnesslo cks
at the rear. Attached to the lower harness lock lugs are
two adjustable harness lap straps with integral lapbelt

The wvival kit accommodates a liferaft, an emergency
oxygen cylinder, and the survival aids. The emergency
oxygen cylinder is mounted to the underside of
the platform, a pressure gauge is on the left thigh support,
and a green manual operating handle is on the left
side of the platform. The emergency oxygen is also
automatically activated during ejection by a static line
coMected to the cockpit floor.
Note
Flow of oxygen from the emergency cylinder
can be stopped by reseating the manual
actuation handle.
A URT-33C radio locator beacon is in a cutout in the
left thigh support and is connected to the cockpit floor
by a static operating cable so that it can be automatically
actuateddmingejection(ifdesired).Thefabricsurvivalaids
container can be deployed on a lowering line after
ejection by pulling on either of the two yellow handles
located on the back side. The liferaft is automatically
inflated when the survival-aids container is deployed.
Contents of the survival-aids container may vary depending
on the area of operation, but the following is a
typical list:
1. Liferafl dye markers
2. Signal flares
3. Morse code and signal card
4. Space blanket
5. Desalter kit or canned water
6. 50 feet of nylon cord
7. Bailing sponge
8. SRU-31/P tlightcmw survival kit,
If over water, the survival-aids container should be
deployed on its lowering line before reaching the surface
to make the raft immediately available on landing. If
over land, it should not be deployed. This will reduce
the risk of entanglement and protect against injury.
2.38.1 .I 0 Rocket Motor. The rocket motor is on the
bottom of the seat bucket. It is ignited by a lanyard
