Backpack

Abstract

A backpack that includes a support vest and a removable pack. The vest includes two shoulder straps and at least one connecting element transversely connecting the shoulder straps in the area of the wearer's back, a rear portion of each shoulder strap and the connecting element forming a support vest rear portion having softness enabling the rear portion of the vest to deform to adapt to the morphology of the back of the wearer, whether the wearer is stationary or moving. The pack of the backpack demarcates a load-receiving volume and includes a front wall having a softness enabling the front wall to deform to adapt to the morphology of the back of the wearer, whether the wearer is stationary or moving, the front wall of the pack having a zone of overlap with the rear portion of the support vest, the front wall of the pack being connected to the support vest by connections allowing relative movement between the front wall of the pack and the support vest, at least vertically or horizontally, or both, in the overlap zone, the connections being located outside of the overlap zone.
