Definitions

• the invention relates to a bag equipped with a load distribution accessory.
• a load carried in a bag is transmitted to the back of the wearer by suspenders which pass over the shoulders of the wearer. If the load is high, the weight of the bag is mainly transferred to the hips (in the case where a waist belt equips the bag) and to the shoulders of the wearer, who can feel excessive and uncomfortable pressure at this level of the body. . Many solutions have been proposed to reduce this uncomfortable distribution of the load on the shoulders of the wearer.
• Patent documents EP2371232 (ADIDAS) or FR2781135 (ROSSIGNOL) describe, for example, a bag comprising a pair of suspenders. A portion of the upper part of each strap is formed by an elastic part limited in elongation. This elastic part aims to decouple the backpack of its wearer on the one hand to improve comfort by allowing the wearer to feel less on his shoulders the movements, generally sudden, during the practice of sport or when moving said wearer .

• the spin of the segments 211, 221 is a constructive solution making it possible to orient the longitudinal portion before 21 and the rear longitudinal portion 22 so that they have a bearing face oriented parallel to the bearing zone.
• This twist solution is particularly well suited when the curved portion 20 and the longitudinal portions 21 and 22 are flat (each having a rectangular cross section for example).
• Figures 9a, 9b and 9c illustrate an embodiment where the curved portion 20 has a round cross section and the longitudinal portions 21 and 22 are flat, for example with a rectangular cross section. This change in section makes it possible to easily orient the bearing face of the longitudinal portions 21 and 22, without it being useful to provide any twist.
• Figures 10a and 10b illustrate another embodiment where the curved portion 20 and the longitudinal portions 21 and 22 are not flat and have the same cross section, for example round or square, giving the frame 2 a certain flexibility.
• the longitudinal portions 21 and 22 each integrate a lateral wing 213, 223 arranged to, in use, be pressed against a region of the trunk of the wearer.
• the lateral wing 213, 223 is advantageously in the form of a flat plate, the length of which is for example between 2 cm and 20 cm and the width of which is for example between 1 cm and 5 cm.
• the lateral wings 213, 223 are for example attached by welding or bonding to the core of the longitudinal portions 21 and 22. The positioning of the lateral wings 213, 223 ensures the orientation of their bearing face parallel to the bearing zone on the wearer's trunk.
• FIGs 11a, 11b and 11c illustrate another embodiment where the segments 211-212, 221-222 are not twisted.
• Each longitudinal portion 21 and 22 has a curve at the flanks F of the carrier P which substantially matches the contour of said flank.
• the curve has a curvature which is offset from the plane containing the curved portion 20.
• Figures 12a, 12b and 12c illustrate another embodiment where the segments 211-212, 221-222 are curved so that they press against the ventral and dorsal support regions of the carrier P.
• Figures 12c illustrate another embodiment where the segments 211-212, 221-222 are curved so that they press against the ventral and dorsal support regions of the carrier P.
• the frame 2 makes it possible to enclose the trunk of the wearer at two support zones: the first region where the front longitudinal portion 21 rests and the second region of the trunk where support the rear longitudinal portion 22. These two bearing zones are located on the same side of the trunk (to the right or to the left of the sagittal plane of the wearer).
• the front longitudinal portion 21 and the rear longitudinal portion 22 of each frame 2 move apart at the level of the trunk of the carrier P and act like jaws, deforming elastically, with a spring effect, to enclose, without injuring it, said trunk.
• the deformation of the frames 2 is induced by the weight of the bag 1 when the latter is carried by the wearer. In other words, it is mainly when the bag 1 is carried by the wearer that the frames 2 deform in order to be put in place and to press at the level of support zones.
• Each frame 2 ultimately forms a load distribution accessory which makes it possible to no longer carry all or part of the weight of the bag 1 on the shoulders ED, EG.
• the physical integrity of the CD, DG collarbones is also more respected than with a conventional bag.
• This accessory allows the weight of the bag 1 to be shifted towards one or more support zones which may be more stressed than the shoulders, with a degree of comfort acceptable to the wearer.
• the inventor notably observed that when a conventional bag had its straps fitted with the frames 2, the load to be worn could be increased from 30% to 50% without significant perception for the wearer. In other words, for the same load, a bag whose straps are fitted with frames 2 appears lighter for the wearer.
• the stiffening reinforcement is of the type described in the aforementioned patent document FR3052650, that is to say in the form of a cane. It has only one longitudinal portion.
• This frame is suitable for fitting a carrying strap for a bag. It has elastic properties so that it deforms elastically with a spring effect when the strap equipped with said frame is installed on a shoulder of the wearer.
• the frame 2 ′ has a curved hook upper portion 20 ′ located, in use, level of the shoulder on which the carrying strap is installed.
• the hooked curved upper portion 20 ' is extended downwards by a longitudinal portion 21' extending, in use, down the trunk of the wearer P, from the ventral side of the wearer.
• the longitudinal portion 21 ' is shaped so that, in use, it is pressed against a region of the trunk of the wearer other than the shoulder on which the carrying strap fitted with the frame is installed. More particularly, the longitudinal portion 21 ′ is shaped so that, in use, said portion is pressed against a ventral region of the carrier (FIG. 7a) or against a lateral flank of said carrier (FIG. 7c).
• the longitudinal portion 21 ′ corresponds to the front longitudinal portion 21 described above, and can be produced according to the embodiments:
• the longitudinal portion 21 ' has a segment 211' which is twisted around the longitudinal axis Aa of said longitudinal portion, so that said longitudinal portion has a bearing face which, in use, is oriented parallel to the support region of the wearer's trunk.
• the segment 211 ’ can be extended downwards by a rectilinear part 212’ .
• the longitudinal portion 21 ’ has a free end 210’ having a flared shape.
• the longitudinal portion 21 ' is shorter.
• the twisted segment 211 ’ can be devoid of its rectilinear part 212’ or the length of the latter can be shorter, for example between 1 cm and 10 cm.
• the curved hook portion 20 ' has a round cross section and the longitudinal portion 21' is flat, for example with a rectangular cross section. This change of section makes it possible to easily orient the bearing face of the longitudinal portion 21 ′, without it being useful to provide any twist.
• - Figures 10a and 10b the longitudinal portion 21 'incorporates a lateral wing 213 arranged to, in use, to be pressed against a ventral region of the wearer or against a lateral flank F of said wearer.
• the curved hook portion 20 'and the longitudinal portion 21' are not flat and have the same cross section, for example round or square, giving the frame 2 'a certain flexibility.
• the longitudinal portion 21 ' has a curve whose curvature ensures, in use, the plating of said longitudinal portion against a lateral flank of the wearer.
• the longitudinal portion 21 ' has a curve whose curvature ensures, in use, the plating of said longitudinal portion against a ventral region of the wearer.
• the free end 200 ′ of the curved hook portion 20 ′ is advantageously bent upwards.
• the strap 11a, 11b is raised upwards at its fastener 110a, 110b, to prevent it from pressing on the trapezoids of the wearer P. The wearer's comfort is therefore increased.
• one or more characteristics set out only in one embodiment can be combined with one or more other features set out only in another embodiment.
• the front longitudinal portion 21 can be made according to one embodiment and the rear longitudinal portion 22 made according to another embodiment.
• the frame equipping the right strap 11 a can be made according to one embodiment and the frame equipping the left strap 11 b can be made according to another embodiment.
• the cross section of the hook portion 20 may be different from that of the longitudinal portions 21, 22.
• the cross section of the longitudinal portions 21, 22 may in particular be wider than that of the hook portion 20 so as to increase the surface of the support area.
• Each twisted segment 211, 221 can be twisted more or less a quarter turn around the longitudinal axis Aa, Ab, according to the anatomy and / or the morphology of the carrier P.
• each twisted segment 211, 221 can for example make an angle between 30 ° and 160 ° with the hook portion 20.
