(FR) DISPOSITIF ET PROCEDE POUR SIEGE ERGONOMIQUE ANTI-FATIGUE
Abstract:
(EN) A method and apparatus is disclosed for periodically and rhythmically lifting first one hip of a seated person and then the other, thereby simulating the muscle stimulation and relaxation imparted to the person through walking while the person is seated. Inflatable air bags (18, 20) provide lift to the seated person while an electric timer (30) and control valve (28) control the timing and distance of inflation.

Des sacs d'air (18, 20) gonflables soulèvent la personne tandis qu'une horloge électrique (30) et une vanne de commande (28) régulent le minutage et la distance de gonflage.
