Definitions

  • the invention relates to a cushion unit for a backpack according to the preamble of claim 1.
  • DE-OS 26 49 067 describes a wire mesh mat made of plastic which is arranged in the back area of a backpack and is permeable to air and is intended to prevent sweating in the back area.
  • a problem with such a wire mesh mat is that wire ends of the mesh come out of the mat and cause damage of the backpack or the clothing of the backpack wearer and / or can affect the wearer of the backpack itself.
  • the object of the present invention is therefore to provide a cushion unit for a backpack, in which it is ensured that no wire ends of the mat can lead to damage or impairment, while at the same time ensuring good air permeability of the cushion unit.
  • the main advantage of the cushion unit according to the invention is that damage to the clothes of the backpack carrier and / or impairments of the backpack carrier are avoided and at the same time it is ensured that the cushion unit is highly permeable to air, so that sweating in the back area is largely avoided.
  • the protective layer which surrounds the braid mat and prevents wire ends or acute-angled wire runs of this mat from passing through consists of a layer which has an air-permeable upper layer, an air-permeable lower layer and between them Has layers arranged support elements that keep the upper layer and the lower layer at a distance. The distance between these layers is preferably about 0.2 to 1.5 cm.
  • the support elements preferably have the form of support rods which run in the direction of the normal to the upper layer and the lower layer.
  • the lower layer, which faces the mesh mat is so dense that no wire ends or sharp bends of the wires or threads forming the mesh mat can pass through it. Even if the mentioned wire ends should press in the lower layer, this is compensated for by the supporting elements, so that the upper layer remains flat.
  • the present padding unit particularly preferably comprises a metal or plastic plate, which rests on the back of the backpack and is concavely shaped in order to adapt to the anatomy of the person by providing at least one, but preferably two, seams running in the transverse direction and spaced apart in the longitudinal direction of the plastic plate are that pull the mesh mat and the protective layer to the plastic plate, so that due to the resulting shortening of the mesh mat in the longitudinal direction, a concave curvature of the plastic plate and thus the entire unit is achieved.
  • the plastic plate can contain cutouts or holes to save weight.
  • the task of which is to create a distance of preferably about 2-3 cm between the back of the backpack carrier and the backpack back wall to form an air ventilation space in the back area of the backpack have a relatively high stiffness so that it is not compressed and does not lose its spacing function.
  • the cushion layer is in the form of a mesh mat, the relatively stiff metal or plastic wires or threads that the Form braid mat or acute-angled bends of the same, protrude to the side of the back of the backpack carrier and cause damage to the clothing of the backpack carrier or even impairment of the backpack carrier itself.
  • the mesh mat is combined with a protective layer which is highly permeable to air and at the same time is so tight and firm that the wire ends or bends mentioned cannot pass through them.
  • this protective layer can also perform a further function, which is to compensate for uncomfortable unevenness in the mesh mat for the comfort of the backpack wearer because of its flexibility.
  • the present cushion unit 1 comprises in its most general form an air-permeable spacer layer or braid mat 2, which is preferably formed from plastic or metal wires 7 and which is preferably bent at its outer edges by heating such that its outer edge regions 3 are bent inwards, and an air-permeable protective layer 4.
  • the braid mat 2 can have the form of a knitted fabric, braid or knitted fabric made of wires, wherein “braid” is also understood to mean the arrangement of spirally running wires or threads.
  • the braid can also have the shape of a layer of horsehair. It is only important that the braid formed is the one mentioned above Distance function to create the air ventilation space fulfilled.
  • the aforementioned bending of the outer edge regions preferably takes place on the opposite longitudinal edges 5 of the mesh mat 2 and preferably also on the opposite transverse edges 6 of the mesh mat 2.
  • the mesh mat 2 preferably consists of loop-like plastic threads or wires 7 which are firmly connected to one another at crossover points, in particular at all crossover points, and which run irregularly between a first surface 21 and a second surface 22 of the mesh mat 2.
  • the thickness of the completely air-permeable mesh mat 2 is preferably about 1 to 4 cm.
  • the entire cushion unit 1 can according to the dotted lines 40 of Figure 2 in the transverse and / or longitudinal direction be sewn several times so that the entire unit is easy to bend.
  • the protective layer 4 consists generally of an air-permeable material layer, which prevents, during use, for example, free wire ends or relatively pointed wire loops resulting from breaks from escaping into the clothing of the backpack wearer, and / or damaging the backpack or the backpack wearer itself in a manner that impairs the exterior. At the same time, an essential effect of the protective layer 4 is also to compensate for unevenness and roughness of the braid mat 2 in a resilient manner.
  • the protective layer 4 consists of a so-called Gare-tex layer, which has an air-permeable first layer 41, an air-permeable second layer 42 spaced therefrom and so-called support bars 43 which run in the direction of the normal to the first layer 41 and the second layer 42 and keep them apart.
  • the thickness of this protective layer 4 is preferably about 1 cm.
  • the protective layer 4 made of the mesh mat 2 is arranged such that it surrounds the mesh mat 2 preferably on all sides, but at least on the side facing the backpack carrier.
  • the unit 1 then consists of the mat 2 and the layer 4.
  • the layer 4 can be covered with the help of an air-permeable cover layer 11, so that the mat 2, the protective layer 4 and the cover layer 11 form the unit 1.
  • the described cushion unit 1 is preferably fastened on a plate-shaped base 9, which preferably consists of a plastic material.
  • a net layer 12 is fastened to the edges of the base 9 such that the cushion unit 1 can be inserted into the pocket formed between the base 9 and the net layer 12.
  • the net layer 12 is preferably sewn at the edge regions of the base 9 (seams 10). After inserting the cushion unit 1, the not yet closed edge of the net layer 12 is sewn onto the base 9.
  • At least one seam 15 running in the transverse direction of the pad unit 1 is preferred, which seams the mesh layer 12 and the pad unit 1 in the direction of the pad 9 pulls, provided.
  • this seam 15 is introduced, the cushion unit 1 is shortened in its longitudinal direction on the side facing away from the base 9. The result of this is that the base 9 is curved concavely.
  • two seams 15, 15 are introduced into the cushion unit 1 at a distance from one another in the longitudinal direction.
  • a layer which dampens this noise development can 16 are provided, which is provided between the overlapping regions of the edges 5, 6 and / or between the surfaces of the mesh mat 2 and the protective layer 4 (FIG. 1).
  • the cushion unit 1 can have a so-called carrier heart part 30, to which the carrier straps 31, 32 are laterally attached.
  • the cushion unit 1 is recessed, so that the carrier heart part 30 is sewn together with the net layer 12 on the base 9.
  • cushion units 1 ′, 1 ′′ and 1 ′′ ′′ on the back of the backpack 14 in the manner shown in FIG. Accordingly, in the lower region of the back of the backpack 14 there is a cushion unit 1 ′′ ′′ running approximately over the entire transverse direction of the back of the backpack 14, to which the hip fins 17, 18 can be attached laterally. Above it are two spaced apart in the transverse direction further cushion units 1 'and 1'', which extend in the longitudinal direction from the cushion unit 1''' to the upper end of the backpack back wall 14 up to approximately the starting points of the shoulder straps.
  • This embodiment is particularly suitable for trekking backpacks in which a concave course is desired in the upper region of the backpack back wall 14 and a convex region adjoining it in the lower region.
  • This course is achieved by the corresponding bending of the support rods 19, 20 extending in the longitudinal direction of the backpack, which preferably consist of aluminum.
  • the cushion units 1 ′ and 1 ′′ can be connected by support straps 23 running in the transverse direction.
  • the protective layer 12 itself can also be attached, preferably sewn, to the back of the backpack 14 to form a pocket, into which the mesh mat 2 can then be inserted.
  • the network layer 12 can be omitted in this embodiment.
