GOING-SAFE - Addressing technical and human factors involved in the implementation of 3-point shoulder harnesses, on all seats, in passenger aircraft
Overview
Background & policy context:
In the course of the DYNASAFE project, experimental prototypes had been built and dynamically tested to validate the concept of a three point shoulder harness, associated to a backrest controlled by an energy absorbing device. The desired performance gains regarding safe passenger restraint, and its compatibility with aircraft floor structures, were positively demonstrated during 2002 paving the way for a new aircraft seating system.
Objectives:
GOING-SAFE, directly following up on the DYNASAFE project, had the aim to progress from experiments to implementation, in addressing the technical, human and commercial factors involved in the development of a novel seating system for aircraft.
The project's specific objectives have been to:
- Take advantage of the methodology and experience of the automotive industry and to integrate them with the expected results of the DYNASAFE project;
- provide air transport with an equivalent level of passive protection, compatible with passenger comfort and airline requirements;
- provide guidelines for a specific in-flight test programme of new seating systems; and
- design an advanced, still experimental batch of seats, equipped with 3-point shoulder harness devices, ultimately readying the concept for manufacture, certification and
installation onboard in-service aircraft.
Methodology:
GOING-SAFE's approach has been to:
- Compile all interface requirements to comply with, while attempting to match the new seating system with the existing aircraft environments;
- perform a preliminary 3D design of a standard economy triple-seat assembly and its components; and
- perform the detailed design of each component, preparing 2D production drawings as well as 3D models of the different economy seat assemblies of a typical
cabin layout shipset.
