The system is partic-ularly suitable for persons who must remain in seated position over long periods, for instance, persons working in offices and the like. The system comprises one or two support surfaces (2) for the feet of the user, which are moved by a motor-driven base (1). Said support surfaces (2) may perform an alternating longitudinal movement, a lifting and lowering movement or a movement combining the latter two. The support surfaces (2) are moved, for example, by means of connecting rods (5) hingedly connected to said support surfaces (2) in the central point (6) and hingedly connected by their other end to eccentric pivots (9) allocated to respective toothed wheels (7) which are mounted with rotational freedom on their respective axis (8), an intermediate motor-driven pinion (10) that conveys rotational movements in opposite direction to the wheels (7) being placed between said wheels. The support surface can be embodied as a bar that is transversal relative to the motor-driven base (1), which is preferably used in collective transport vehicles such as motor coaches, airplanes, etc.

L'invention concerne un système permettant à des personnes assises d'exercer leurs extrémités inférieures, convenant particulièrement à des personnes qui doivent rester en position assise pendant de longues périodes, comme par exemple dans les bureaux et analogues. Ce système consiste à installer, pour les pieds de l'utilisateur, une ou deux surfaces d'appui (2), entraînées au moyen d'une base motorisée (1), ces surfaces d'appui (2) pouvant suivre un mouvement longitudinal alternatif, un mouvement ascendant et descendant ou un mouvement combinant lesdits mouvements. Les surfaces d'appui (2) sont entraînées, par exemple, au moyen de bielles (5) articulées sur le point central (6) desdites surfaces d'appui (2) et également articulées, par leur autre extrémité, à des pivots excentriques (9) associés à des roues dentées respectives (7), montées avec une liberté de rotation sur leurs axes respectifs (8), entre lesquelles est situé un pignon intermédiaire moteur (10), qui transmet les mouvements de rotation dans le sens contraire des roues (7). Les surfaces d'appui peuvent être matérialisées par une barre qui est transversale par rapport à la base motorisée (1) et qui trouve, de préférence, une application dans des véhicules de transport collectif, comme par exemple, des autocars, des avions, etc.
