This device is noteworthy in that it comprises two means of positional control and adjustment (M1-M2) made using manual remote controls that are independent of one another and that allow the position of the back frame to be adjusted with respect to the carrying harness, the first means (M1) allowing the back frame to be raised with respect to the harness and the second means (M2) allowing the back frame to be lowered with respect to the harness, and in that the back frame is designed to receive an endless belt (5) arranged in its median longitudinal plane, said belt being secured by a strand to the carrying harness and allowing the back frame to move relative to the harness via the positional control and adjustment means (M1-M2), and in that a locking mechanism (11) tensioned by the second control means (M2) acts and locks the endless belt (5) in position or releases it according to the desired phases of movement, and in that said control means (M2) includes a strap, one end (6a) of which is secured to the connecting belt (5) and to the harness and the other end of which is designed to form the control handle, said strap passing over the locking mechanism (11), bearing on the latter and actuating it.
Ce dispositif est remarquable ce qu'il comprend deux moyens de commande et réglage en position (M1 - M2) établis à l'aide de commandes manuelles à distance, autonomes l'un par rapport à l'autre, et autorisant le réglage en position de la structure de dos par rapport au harnais de portage, le premier moyen (M1) permettant le relevage de la structure de dos par rapport au harnais, et le second moyen (M2) l'abaissement de la structure de dos par rapport au harnais, et en ce que la structure de dos est aménagée pour recevoir une courroie sans fin (5) disposée dans son plan longitudinal médian, ladite courroie étant solidarisée par un brin au harnais de portage et permettant le déplacement relatif de la structure de dos par rapport au harnais par le ou les moyens de commande et réglage en position (M1 - M2), et en ce qu'un mécanisme de verrouillage (11) sollicité par le second moyen de commande (M2) agit et autorise le blocage en position de la courroie sans fin (5) ou sa libération selon les phases de déplacement souhaitées, et en ce que ledit moyen de commande (M2) inclut une sangle dont une extrémité (6a) est solidarisée à la courroie de liaison (5) et du harnais et l'autre extrémité est agencée pour constituer la poignée de commande, ladite sangle contournant le mécanisme de verrouillage (11) en prenant appui sur ce dernier et provoquant sa mise en fonctionnement.
