The dynamic support (1) comprises means (3) for the cyclic inflation and deflation of an air chamber (2). The air chamber (2) is divided into two half-chambers (2A) having a common rigid laminar element (4) to be positioned on a seat back. When the half-chambers (2A) are inflated they press mainly against the muscular tissue of the lumbar region of the user's back, with the exception of his vertebrae and ribs. |
