A LOAD-CARRYING DEVICE ATTACHED TO THE USER'S BODY, A SET FOR RETROFITTING SUCH A LOAD-CARRYING DEVICE, AND A METHOD FOR RETROFITTING SUCH A LOAD-CARRYING DEVICE

摘要

The device includes a front brace (1), a non-stretchable lumbar brace (2), and a right and left under-shoulder strap (3,4) and right and left hip strap (5, 6). All the straps (3, 4, 5, 6) are non-stretchable and the under-shoulder straps (3, 4) are adjustable in their length. The front brace (1) has attachment points (8, 9, 12, 13) to the front ends the ends of all straps (3, 4, 5, 6) and the lumbar brace (2) has attachment points (10, 11, 14, 15) to the rear ends of these straps. Attachment points (8, 9) for under-shoulder straps (3, 4) to the front brace (1) are above the attachment points (12, 13) of the hip straps (5, 6) to this brace (1). Attachment points (8, 9) for under-shoulder straps (3,4) to the front brace (1) are located above their attachment points (10, 11) to the lumbar brace (2). Attachment points (12, 13) for the hip straps (5, 6) to the front brace (1) are located below their attachment points (14, 15) to the lumbar brace (2). The distance (L1) between the attachment points (8, 9) of the under-shoulder straps (3, 4) to the front brace (1) and the distance (L2) between the attachment points (12,13) of the hip straps (5, 6) to the front brace (1), do not exceed preset values. The distance (L3) between the attachment point (8) of the front brace (1) to the right under-shoulder strap (3) and the attachment point (12) of the front brace (1) to the right hip strap (5) as well as the distance (L4) between the attachment point (9) of the front brace (1) of the left under¬ shoulder strap (4) and the attachment point (13) of the front brace (1) to the left hip strap (6) are not less than preset values. The attachment points (12, 13) for the hip straps (5, 6) to the front brace (1) are located in the space limited by vertical planes (26, 28) parallel to the plane of symmetry of the user's body and tangent to the internal surfaces of the user's upper anterior iliac spines (25, 27). The retrofitting set may include: two non-stretchable under-shoulder straps (78, 3, 4) adjustable in length, at their ends provided with means (66, 67, 68, 70, 71) for connecting them to the carrying device; two elongated rigid struts (18, 19) at their ends provided with means for connecting them with the carrying device, or analogous struts (18, 19) connected with their lower ends to the hip belt (7). The method of retrofitting consists in attaching the selected set to the load-carrying device by means connecting it at the indicated places.
