A suspended-load backpack designed to permit the load to move relative to the backpack frame during walking and running so that the large movements between the load and the frame of the backpack reduce the fluctuations of absolute vertical motion of the load. Because the hip (and thus the pack frame) go up a down a good deal during walking, a large relative movement between the frame and the load reduces the absolute excursion of the load. This movement may be, in turn, transferred to a motor through, for example, a rack and pinion gear, to convert the mechanical movement to electrical energy. The movement may also be converted to electrical energy by using an electroactive polymer (EAP) to connect the suspended load to the frame. Such designs allow the load to move in a controlled fashion to prevent the patient from losing his or her balance as the load moves up and down along the backpack frame. Such movement of thesuspended-load relative to the frame also reduces the forces on the wearer's shoulders while walking or running, thus reducing the likelihood of orthopedic injury.

L'invention concerne un sac à dos à charge suspendue conçu pour permettre à la charge de se déplacer par rapport à l'armature du sac à dos pendant la marche et la course de sorte que les mouvements importants entre la charge et l'armature du sac à dos réduisent les fluctuations du mouvement vertical absolu de la charge. Etant donné que le bassin (et donc l'armature du sac) monte et descend continuellement pendant la marche, un mouvement relatif important entre l'armature et la charge réduit la course absolue de la charge. Ce mouvement peut à son tour être transmis à un moteur par l'intermédiaire d'un engrenage à crémaillère, par exemple, en vue d'une conversion du mouvement mécanique en énergie électrique. Le mouvement peut également être converti en énergie électrique par utilisation d'un polymère électro-actif (EAP) pour relier la charge suspendue à l'armature. Ces conceptions permettent à la charge de se déplacer de manière régulée, l'utilisateur ne perdant pas son équilibre lorsque la charge monte et descend le long de l'armature du sac à dos. Le mouvement de la charge suspendue par rapport à l'armature permet en outre de réduire les forces exercées sur les épaules de l'utilisateur pendant la marche ou la course, d'où un risque réduit de lésion orthopédique.
