Definitions

  • This invention relates to an anatomical and biomechamcal support element, in particular a back-rest or cushion, in accordance with the precharactensmg part of the main claim.
  • An object of this invention is to provide an anatomical and biomechamcal support element, in particular a back-rest or cushion, which obviates the aforesaid drawbacks and, in particular, reduces perspiration and microtraumas of those parts of the user's body in contact with the element.
  • a further object is to provide a support element the rigidity of which can be adapted to the user's requirements, and which is of simple ano qu ⁇ c ⁇ construction
  • Figures 1 and 2 are a schematic front and side view of a support element in the form of a back-rest according to the invention
  • Figures 3 and 4 are a schematic section therethrough on the lines 3/3 and 4/4 of Figure 1 ;
  • Figures 5 and 6 are a schematic front and side view of a first variant of the back-rest shown in Figures 1-4;
  • Figure 7 is a schematic perspective view of the back-rest of Figure 1.
  • Figures 1-4 show a support element in the form of a back-rest, comprising: an outer shell 1, an inner wall 2 closing the cavity 3 ( Figure 3) defined by said shell , and an inflatable stiffening element 34 provided within said cavity 3.
  • the outer shell 1 comprises a wall 4 making contact with the user's back, and lateral walls 5.
  • the wall 4 is curved to follow the natural curvature of the back and has a plurality of projecting sectors 6, 7A- B, 8, 9, 10, 11, 12.
  • the central sectors 8, 9, 10 are distributed along the longitudinal axis L of the back-rest and make contact with the user's spine.
  • the sectors 8, 9, 10 are in the form of an elongate arch, their distance D1 , D2, D3 from the closure wall 2 decreasing starting from the highest sector 8 In this manner the sectors 8 are able to rest against the cervical region of the spine, the sectors 9 against the central part of the spine and the sector 10 against the lumbar region.
  • the projecting sectors 6 and 7A, B are circular, to rest respectively against the back interscapular region (sectors 6), against the back central region (sectors 7A) anc against the lumbar region (sectors 7B).
  • the sectors 6 and 7A, B each have a through hole 13 positioned at their point of maximum curvature
  • a metal ring 14 is positioned about the edge of the hole
  • the distance B1 between the point of maximum curvature of the sectors 6 and the closure wall 2 is greater than that of the other circular sectors 7A, B.
  • Those sectors 7A closer to the sectors 6 have a distance B2 which is less than the distance B1 of the sectors 6 and than the distance B3, B4 of the most central sectors 7A and 7B.
  • the lowest sectors 7B have distances B5, B6 which are less than that of the most central sector 7B, these distances themselves also decreasing in that order.
  • the lateral sectors 11 and 12 rest against the lateral dorsal and lumbar regions of the back respectively, and for this purpose have distances C1 , C2 which gradually increase from the top of the back-rest downwards.
  • the back-rest of the invention ensures anatomically correct bearing of the back-rest user's back.
  • the lateral walls 5 of the outer shell 1 comprise a plurality of through holes 20 ( Figure 2) to enable air to enter and leave the cavity defined by the shell.
  • the shell 1 advantageously comprises edges 14A, B to which the inner wall 2 is joined, for example by sewing.
  • the outer shell 1 is provided with an additional part 15 acting as a base wall for the rucksack.
  • This additional part is advantageously formed in one piece with the part forming the actual back-rest so that it can be folded at 90°C to the back-rest, to be sewn to the other constituent parts of the rucksack and hence form the rucksack base.
  • the base part 15 also has projecting sectors 16 to improve the stability of the rucksack when rested on the ground, and also improve its overall appearance.
  • the outer shel l 1 and the possi bl e part 15 are prefe rabl y const ructed by thermoformi ng pol yethyl ene , fo r exampl e of t he closed cell expanded type, or of a semirigid material which can be thermoformed or preformed.
  • the inflatable stiffening element 34 comprises an inflatable liner 17 extending substantially over the entire back-rest and preferably having that face in contact with the back-rest wall 4 shaped with projections 18, 19 ( Figures 3, 4) arranged to copenetrate the cavities defined by the outwardly projecting sectors 6, 7A, B, 8, 9, 10, 11, 12 of the back-rest.
  • the projecting parts 18 of the inflatable liner 17 which are to fill the cavities of those sectors 6, 7A, B having aeration holes 13 copenetrate the cavity formed by these sectors only partially, so as not to block the holes 13 and to enable air to enter and/or leave these holes.
  • the inflatable liner 17 is connected by a tube 21 emerging from the shell 1 ( Figure 1 ) to a conventional pump member 23 of the type also provided with a valve 22, for example of screw type, enabling the liner to be deflated.
  • the pump 23 and relative tube 21 are preferably fixed (in a manner not shown but conventional for an expert of the art) to one of the component parts of the rucksack, for example to a side wall thereof or to one of the lateral walls 5 of the shell 1, but could also be left free, to simply project from the shell 1.
  • the inflatable liner 17 is formed of any plastic material suitable for the purpose.
  • the inner wall 2 can be formed of any known suitable plastic material of sufficient rigidity to prevent the inflatable element 34 expanding inwards when inflated.
  • the back-rest of the invention can be used not only to form rucksacks but also seating members in general, seat paddings or additional supports for seating parts, in particular for automobile seats.
  • the holes 13 and 20 provided in the back-rest shell 1 ensure that, in relation to the movements of the user's back, an air flow is created entering and/or leaving said holes to limit user perspiration. It should also be noted that because of the provision of the holes 13 and 20, on using the back-rest there is continuous inflation and deflation of the chamber bounded by the shell 1 and wall 2, causing a continuous variation in the rigidity of the back-rest. In this manner, the action of the sectors 6, 7A, B, 8, 9, 10, 11, 12 provides a biomechanical effect which massages the user's back.
  • the back-rest of the invention also prevents microtraumas arising.
  • the length of the back-rest and/or the number and shape of the projecting sectors 6-12 could be different from those illustrated. They could for example also be in the form of depressions in addition to projections.
  • Figures 5-6 show for example a back-rest to be used for larger-capacity rucksacks that the back-rest of Figures 1, 2 (those parts common to the two embodiments are indicated by the same reference numerals).
  • the backrest of the invention could also be used without the inflatable stiffening element 34, which could be dispensed with or replaced by another element or material able to perform a similar stiffening function.
  • the support element can also be in the form of a cushion (not shown) and be shaped in known anatomical manner, to receive and support the user's buttocks.
  • the support element again comprises a shell having a plurality of projecting sectors provided with air circulation holes, and a stiffening element of air chamber type.
  • the cushion can be used in all types of seats, including saddles for sporting and non-sporting activities.
  • the cushion could be associated with the already described backrest and be constructed in one piece or in two pieces with said back-rest .
  • the support element of the invention can also be advantageously used to alleviate problems deriving from lengthy periods in bed.
  • the support element is constructed as already described but in the form of a mattress.
