AIRCRAFT PILOT SEAT

I) ABSTRACT:

This paper is concerned with a cockpit seat for civilian aircrafts which is designed to withstand a 16G crash test.

II) TECHNICAL PROBLEM TO BE SOLVED: 5 A cockpit seat is attached to the cockpit floor only through a base that must be structurally very strong to pass the crash test 16G type certification. As a consequence, this base has a high weight due to its reinforcements. 10 III) SPECIFICATION:

This paper describes a connecting device to link a pilot seat to the aircraft wherein (See figure 1), the connecting device is a rope, a strap, or a bar fixed at a first end to the rear of the seat back and at a second end to the aircraft, e.g. to the ceiling of the cockpit, to the floor of the cockpit or to a vertical wall of the cockpit at the rear of the seat. 15 The connecting device adds a point of attachment of the seat with the aircraft, and thus, makes it possible to reduce the reinforcements of the base and consequently the weight of the seat.

20 Fig 1: Seat with connecting devices in different configurations: attached to the ceiling, floor, or cockpit wall. The connecting device can be permanently or temporarily attached to the aircraft or the seat in order to avoid constant interference with the possible traffic on the rear of the seat. 25 In this paper, when the connecting device is a bar, it is understood that the connecting device is rigid, linear.

In the particular case of a rope or a strap, the connecting device has advantageously an L-shape (See figure 2) thanks to a fixation anchor (which is adapted to no longer retain the rope/strap when a tension superior to a critical tension is exerted on the rope/strap) to th...
