Abstract

L'invention concerne un fauteuil roulant dont la suspension est souple et conçue pour absorber et filtrer les vibrations. Le train arrière comporte un triangle (1) fixé à un châssis-poutre, un pivot-fusée (15) qui porte la roue (R) et une jambe de force (6) avec appui sur un amortisseur central (10). Les roulettes avant sont montées sur un système double (21, 26) qui filtre les vibrations. Meilleur confort et compensation du dévers. Possibilité de passer d'une utilisation intérieure à extérieure sans modifier le carrossage des roues. Coque moulée pour le maintien.
