ABSTRACT:
The present invention relates to rucksacks of the general type comprising a body defined by a padded backrest to the perimeter of which is secured a bag portion and a pair of shoulder straps, each strap having its ends connected to the bottom part and to the top part of the body of the rucksack in the vicinity of the backrest. The invention can be applied to any type of rucksack, but is particularly designed for application to the so-called school rucksacks.
The purpose of the present invention is to provide a rucksack of the type specified above that will guarantee or in any case will favour as much as possible a correct posture of the user, and in particular correct resting of the rucksack on the user's spine, with particular regard to the possibility of the load carried in the rucksack being relatively heavy, as, for example, frequently occurs in the case of rucksacks for school children.
With a view to achieving this purpose, the subject of the invention is a rucksack of the type indicated above, the main characteristic of which lies in the fact that, associated to the backrest of the rucksack are elastic-strip means comprising at least one elastic lamina or strip lying in a plane parallel to the backrest and having its ends operatively connected to the backrest in such a way that a deformation due to bending of the backrest according to the dorsal arch of the user generates an elastic reaction of the aforesaid strip means tending to cause the backrest to return to the undeformed condition.
In a preferred embodiment of the rucksack according to the invention, the aforesaid elastic strip has a first end secured to the backrest, and a second end, which is also secured to the backrest but with the possibility of relative displacement in the vertical direction of the backrest. For instance, in a specific embodiment the aforesaid second end of the elastic strip is engaged in a loop on the backrest.
Thanks to the above characteristics, the rucksack according to the invention can advantageously have the function of elastic stiffening for it to rest correctly on the spine of the user, this advantage being absent in the rucksacks made up to now.
