Definitions

  • the present invention relates to a device for protecting the human body from impacts according to the preamble of claim 1.
  • the applicant's AT 397 950 B describes an improved damping device, in which the damping effect is not produced by a solid, such as foam is, but by a volume of air that is enclosed in the damping device and that can escape from it in a controlled manner during an impact.
  • a very light foam body is arranged, which is only designed for this purpose is to keep the outer casing of the device stretched in its unloaded state. Since the foam body itself makes only an insignificant contribution to the damping effect the temperature dependence is also not a problem. In this way, considerable Improvements over the previously known damping devices can be achieved.
  • a protective device is known from FR 2 676 178 A in which foam bodies are provided are to dampen shocks. The disadvantages described above occur.
  • EP 0 836 811 A shows a body protection element which consists of a molded body filling Has shaped bodies movable relative to each other. The damping effect of such However, the device depends very much on the geometric arrangement of the moldings at the time of the impact, and is therefore not sufficiently reproducible.
  • WO 92/04210 describes a damping system for use in vehicle doors is known, which consists of a variety of rectangular cuboid cells. Also With this solution, the damping effect is caused by the air flowing out of the cells achieved.
  • the overall thickness of the device is limited for a variety of reasons, the The burden on the test subject can be kept as low as possible only if the force as uniform as possible can be built up over the entire thickness of the damping device can. In addition, the damping effect should be as independent of the location of the Hitting the obstacle.
  • the object of the present invention is to develop the devices described above in such a way that that under comparable circumstances, the impact of the person on a shock can be kept as low as possible. Conversely, for a given quality of the Protection, the thickness of the damping device should be as small as possible.
  • convex is understood to mean that the respective chamber is crowned in the unloaded state, d. H. neither protruding areas, nor flat surface areas to a significant extent.
  • the convex chambers are approximately cylindrical and have on them Ends outward rounded caps.
  • the convex chambers be essentially spherical or rotationally elliptical.
  • the cylindrical chambers can also be flattened at the end be completed in the form of a tube.
  • the convex chambers have a shape which already penetrates an object, even if it is not fully loaded opposed significant resistance from the start. This effect is in the Invention achieved in that largely avoided that in such a case the device can be compressed locally without any significant resistance because the Bulge the side walls of the chamber in question.
  • a particularly uniform damping effect in all directions is preferred in that the at least one convex chamber is completely filled with foam is.
  • the foam body with recesses in order to to favor the air distribution.
  • the outer casing is provided with a pressure distribution plate or baffle plate known per se, which covers at least one of the convex chambers.
  • a pressure distribution plate or baffle plate known per se, which covers at least one of the convex chambers.
  • a baffle plate be both rigid and elastic.
  • the baffle plate about the shape of a scale armor.
  • a special comfort is achieved in that on the side facing the body Outer shell a known seat shell adapted to the body shape is provided, and that incompressible spacer elements attached between the outer shell and the seat shell are. Depending on the construction, the spacer elements can either be on the seat shell or on be attached to the outer shell.
  • a plurality of convex chambers are provided which are mutually in unloaded Touch condition and that the air-filled spaces between the convex chambers and the outer shell are free of foam bodies.
  • the gaps will wear also contribute to the damping effect, since they are also filled with a volume of air are suitable for cushioning an impact, but they do not need to be done by yourself Foam body to be stretched as this is due to the surrounding convex chambers he follows. In any case, the gaps should also be ventable.
  • the convex chambers have air passage openings that open into adjacent chambers. In this way it is achieved that the air initially in the event of an impact in the region of one of the convex chambers must flow out of this chamber into the surrounding rooms. This will next to the actual damping effect in the area of the convex chamber in question achieved that the surrounding portions of the device are subjected to a higher pressure so that they are better prepared for the further spread of the impact.
  • a convex chamber is formed in an edge portion of the device, can preferably be provided that a wall section of at least one convex chamber also forms part of the outer shell.
  • an outer shell 1 which covers the entire Device tightly encloses.
  • three convex chambers 2a, 2b, 2c provided, which are also designed as closed bodies.
  • the convex chambers 2a, 2b, 2c are connected to the outer shell 1. It is alternatively also possible, the necessary connections by gluing, welding to realize.
  • the convex chambers 2a, 2b, 2c are completely with Foam bodies 4a, 4b, 4c filled out of a light open-pored material. The Density of the material is selected so that the clamping force is just sufficient, the chambers 2a, 2b, 2c to be kept open in its fully open form in the unloaded state.
  • the respective foam body 4a, 4b, 4c can be made somewhat larger be as the associated chamber 2a, 2b, 2c.
  • the cross section of these chambers 2a, 2b, 2c is then essentially circular.
  • the Chambers 2a, 2b, 2c have in their central section the shape of a cylinder, the The axis is perpendicular to the plane of the drawing in FIG. 1.
  • the chambers are at both ends 2a, 2b, 2c in any case essentially spherical.
  • the space between the chambers 2a, 2b, 2c is also filled with foam bodies 5a, 5b. This also ensures the desired shape between these chambers 2a, 2b, 2c.
  • Both the material of the outer shell 1 and the material from which the convex Chambers 2a, 2b, 2c are made air-permeable to a predetermined extent. This air permeability can be achieved either by the material itself is air permeable, or in that an air permeable material with holes of predetermined Dimensions is provided. If attempted by a force acting in a jerk is to compress the chambers, the air volume contained therein first compressed and then exit through the material in a controlled manner. To this The shock force is dampened and passed on to a person in this damped form, which uses the device.
  • the device shown in FIG. 1 is approximately designed as protection for the buttocks and back of a paraglider.
  • a baffle plate 6 is provided, which serves to the device in front of the To protect small obstacles, such as pointed stones, from entering.
  • the front edge 6a of the Baffle plate 6 is bent up to slide off, for example when landing with a tail wind enable flat ground, as is the case with a sled, for example.
  • a seat shell 16 is provided, which is adapted to the body shape.
  • the baffle plate 6 distributes the force to the convex chambers 2a, 2b and the intermediate section, which in turn are supported on the seat pan 16.
  • This area of the device then forms, as it were, a single chamber which is pressurized by the force F 1 . Since this chamber has only convexly outwardly curved outer surfaces, there is no way to significantly reduce the thickness of this chamber with the same internal volume, as would be the case if the chamber had flat boundary walls. Therefore, the force F 1 is resisted from the beginning and the entire thickness D of the device is available to dampen the impact.
  • the damping essentially takes place through the chamber 2c.
  • the convex shape of this chamber ensures that the force acting against it is resisted from the start.
  • a further advantageous effect results from the fact that the chamber 2c is arranged entirely within the outer shell 1, so that the air initially exits the chamber 2c into the interior of the outer shell 1. In this way, to the extent that the chamber 2c is compressed, the remaining part of the device is biased by an internal overpressure. Since the affected area usually expands in the course of an impact, greater damping forces are then available in the adjacent areas, which better prevent the obstacle from striking through.
  • the various seams with which the outer casing 1 is sewn together is designed to be permeable to air. Otherwise these seams are made airtight. Furthermore, it is possible to provide openings with predetermined dimensions in order to to control the air outlet.
  • a plurality of convex chambers 2d, 2e, 2f, 2g and 2h are arranged within the outer shell 1 in such a way that they touch the respectively adjacent chambers.
  • the chambers 2d to 2h are filled with foam bodies 4d to 4h in order to open them. Since the external shape of the device is essentially predetermined by these chambers 2d to 2h, it is not necessary to also fill the space between these chambers with foam.
  • Essential are the chambers 2e and 2g, which are each arranged at the apex of the angular configuration of the device. In this way, a force that acts obliquely in the direction of arrow F 3 can be absorbed in a particularly advantageous manner. Such a force can only be damped in an extremely unsatisfactory manner with conventional devices.
  • the variant of FIG. 2 differs from the variant of FIG. 1 in that the outer shell 1 is glued to the chambers 2d to 2h and that the corresponding External sections of the chambers 2d to 2h simultaneously represent the outer casing 1.
  • a seat shell 16 is designed as a seat for one person.
  • a chamber 2j is provided centrally in an outer shell 1.
  • wedge-shaped spacer elements 7a, 7b is provided between the seat shell 16 and the outer shell 1 in order to prevent the outer casing 1 from becoming deformed in the event of an oblique impact, which could lead to a reduction in the damping path.
  • a oblique impact forms one of the two adjacent chambers 12a, 12b with the middle Chamber 2j has a substantially convex area, which is also good in this case Protective effect guaranteed.
  • the present invention enables the physically predetermined boundary conditions to dampen impacts on human bodies as far as possible and the Significantly increase safety in a variety of accident scenarios.
