Abstract
Système amortisseur contre les vibrations et les déformations d'un plancher transmises à un objet tel qu'un siège. Le système de support d'un siège 12, 14 monté sur un mécanisme amortisseur 16 à 19 comporte deux coulisseaux montés sur des rails 32, chacun comportant des blocs d'isolement contre les vibrations et les déformations 72, 74, chaque bloc comportant un manchon de montage maintenant un élément en caoutchouc ayant une ouverture centrale de passage de la cheville de l'élément 16 ou 20 du mécanisme; celui-ci comportant une pièce rapportée pouvant être écrasée, le montage étant tel que les vibrations et des déformations du plancher jusqu'à 10 degrés n'influent pas sur le mécanisme de montage du siège. Application en particulier à un siège ou autre aéronef.
