<p>The invention relates to a system which can be fitted to a chair, in which deformable, especially inflatable, elements (4, 5, 6, 8, 9, 10), whose passage from a retraction state to an expansion state and vice versa involves well-defined sequences of movements of the human body, are in communication with a circuit (30, 23, 32, 33) and a source of power, especially of pressurised fluid (22), comprising control means (40, 41) placed under the dependence of a programmer (42) automatically ensuring alternate phases of expansion and of retraction which give rise to stress displacements in human joints and tissues in general, a stabilisation of the human body, in itself and relative to the chair, and a stimulation of a reflex activity of tonic muscles. This programmed-dynamism system aims to periodically assist the user in getting up more easily from the chair in order more easily to subsequently readapt thereto in order to obtain greater comfort and to maintain his alert state. <IMAGE></p> |
