Abstract

To make the passenger seat for the airplane as light as possible while satisfying safety requirements, some or all the essential components are made with a sandwich-like structure, especially from sandwich panels. These sandwich panels can be made from a plurality of covering layers with a light but strong supporting core (e.g. with a honeycomb structure) interposed between pairs of covering layers.
