Front Seat Inflatable Restraints
An inflatable shoulder harness is integral to each front seat harness. The
electronic module assembly, mounted below the cabin floor, contains a
crash sensor, battery, and related circuitry to monitor the deceleration rate
of the airplane. In the event of a crash, the sensor evaluates the crash pulse
and sends a signal to an inflator assembly mounted to the aft seat frame.
This signal releases the gas in the inflator and rapidly inflates the airbag
within the shoulder harness cover. After airbag deployment, the airbag
deflates to enable the pilot/co-pilot to egress the airplane without obstruc-
tion.
The crash sensor’s predetermined deployment threshold does not allow
inadvertent deployment during normal operations, such as hard landings,
strikes on the seat, or random vibration.
To Use Restraints
• CAUTION •
No slack may exist between the occupant’s shoulder and restraint
harness shoulder strap.
Stow the seat belts in the latched position when not in use.
1.
Slip arms behind the harness so that the harness extends over shoul-
ders.
2.
Hold the buckle and firmly insert the link.
3.
Grasp the seat belt tabs outboard of the link and buckle and pull to
tighten. Buckle should be centered over hips for maximum comfort
and safety.
4.
Restraint harnesses should fit snug against the shoulder with the lap
buckle centered and tightened around the hips.
To Release Restraints
1.
Grasp the top of the buckle opposite the link and pull outward. The
link will slip free of buckle.
2.
Slip arms from behind the harness.
Child Restraint System
To Install Child Seat (Serials w/ 2+1 Rear Seat)
The aircraft is equipped with provisions for installing two LATCH
compliant child seats in the outboard rear seat positions, OR one
non-LATCH compliant seat in the center rear seat position.
Lower anchors for the LATCH compliant seats are located in the outboard
seat positions. The non-LATCH compliant seat must be installed using the
center seat belt. Three top tether anchors for the child seats are located on
the rear bulkhead.
