Definitions

  • the invention relates to padding, for example for crash helmets, car seats or the like, which are in direct contact with human limbs or parts of the body over long periods of time.
  • upholstery is preferably used as a resilient interior for items of clothing made of hard materials in order to achieve a body-side surface which is adapted as possible to the anatomy of the respective body part for comfortable wearing of the item of clothing.
  • these upholsteries are also useful for lining conventional seats and couches, but also for medical devices that are used, for example, to support and support the human skeleton and therefore have to be in constant contact with the body.
  • shock-absorbing or impact-absorbing property of padding materials already known from the prior art makes particular use of the professional world to improve the protective effect and the wearing comfort of protective equipment such as crash helmets.
  • a helmet lining of this type is shown for example in DE-OS 3 540 883.
  • This known helmet lining of an integral helmet has a dimensionally stable, shock-absorbing outer lining in the form of a shell and an inner soft, air-permeable lining which is arranged on the inside of the outer lining.
  • the inner lining together with the outer lining, forms a network of ventilation channels, which are formed by intersecting radial depressions in both the inner and the outer lining at the respective contact surfaces.
  • this integral helmet has two air catchers arranged on both sides in the lower side area, which enable an air supply to the ventilation network via connecting channels.
  • a ventilation opening connected to the ventilation system is accordingly provided, so that an air circulation takes place while driving, with air exchange of the fresh air in the ducts with the moist air in the helmet inner region via the open-pore inner lining.
  • the soft upholstery of the head shape is pressed together to different extents, so that the ventilation ducts can become blocked by the soft upholstery that is pressed in in highly stressed areas.
  • the result of this is that in these areas there is no longer any ventilation of the inner helmet inner area, while in the remaining channels larger flow velocities can be generated in the remaining channels, which lead to an uncomfortable feeling for the wearer.
  • the relatively thin inner padding on the highly stressed areas is quickly pushed down to the outer, dimensionally stable padding, which can cause uncomfortable and painful pressure points on the relevant part of the body at these sections.
  • the hood as provided in claim 2, is provided on the outside with a number of projections, these projections which extend in the longitudinal direction are arranged in accordance with the different deformation of the covering in such a way that the relative distances between two adjacent projections are particularly pronounced expand deformed or stretched areas accordingly, creating a larger contact area for the inner padding on the dimensionally stable lining without the flow cross-section being reduced from the sum of all channels as a whole.
  • the course of the flow channels can be maintained without any substantial change even after the lining adapter has been inserted further as a result of the device according to the invention, which is designed according to claim 1.
  • the device according to the invention can provide an upholstery whose surface contour on the body side corresponds exactly to that of the body part to be covered, and in the case of the development according to claim 9, the later internal flow channels in the lining or in the lining adapter essentially bypassing the highly stressed areas Force lines follow the expected surface force distribution.
  • the subsequent surface loading of the upholstery during wear can be made uniform, so that no pressure points can arise.
  • a further development of the device according to the invention provides for a load on the still plastically deformable padding material for the lining or the lining adapter during the shaping to suit the body, which essentially corresponds to the later real pressure load. This can further improve the simulation of the real wearing or loading condition of the upholstery.
  • the simulation of the real load condition is advantageously realized by applying the hard object to be adapted during the hardening phase of the applied or filled up padding material for the lining or the lining adapter under essentially real conditions until there is sufficient dimensional stability of the padding material allows removal of the adapted object from the body part.
  • This measure also has the advantage that additional machining of the side of the lining facing away from the body to adapt to the corresponding contour of the object to be cushioned can be omitted.
  • the design of the projections as separate components has the further advantage that any flow channel pattern with different channel cross sections can be produced with little effort.
  • each liner shell being made for itself and then pushed into one another.
  • This measure according to the invention makes it possible to manufacture the helmet in a predetermined oversize of the outer lining shell, in order to subsequently individually use the inner lining shell which acts as an adapter, without any subsequent change in the helmet and adapter geometry or the flow channels incorporated into the inner lining shell to adapt to the respective head shape of the wearer according to claim 7.
  • the additional arrangement of ribs on the outside of the hood can be dispensed with. In this case there is also no need to pull the covering off the hardened shock-absorbing material, which ensures a smooth surface of the adapter.
  • the helmet can be brought into any position relative to the inner lining shell according to the needs of the wearer and then fixed to the inside of the outer lining shell with the outside of the inner lining shell.
  • a Velcro or adhesive connection can be provided instead of the holding device in the form of interlocking projections and recesses on the contact surfaces of the lining shells.
  • the helmet can also be fixed to the inner lining shell simply by means of a press fit.
  • FIG. 1 shows a first exemplary embodiment of the device according to the invention for producing a body-appropriate upholstery, in which a covering is provided which is in the form of a hood 50 for adapting a lining 8 to a head shape.
  • the hood 50 consists of an elastically deformable material, preferably of a rubber material, which is shaped according to a helmet upper part 1 of an integral helmet according to FIG. 3 or 6 into a shell with a standard head size, the edge contour of which in the side view essentially follows that of the helmet upper part 1.
  • the outer edges of the elastic hood 50 are bent into a semicircular channel 51 which surrounds the hood 50 as a closed circular ring.
  • the outside of the hood 50 has a number of essentially equally spaced projections 52, each of which extends from a front or face-facing shell edge over the outside of the hood 50 in the direction of the rear or neck-facing shell edge.
  • the projections 52 are integrally formed with the hood 50 made of the same hood material.
  • the projections 52 are also possible to manufacture separately from an elastic material, for example from rubber, and to install them on the outside of the hood 50 in any orientation as required.
  • a plug connection according to the rivet-eye principle or a simple Velcro connection can be provided as a suitable fastening option for the projections 52.
  • other fastening variants such as gluing or welding can also be used.
  • Each projection 52 has a trapezoidal cross-sectional area with a height of approximately 2 to 4 mm and an average width of approximately 10 mm.
  • a further projection 53 is formed in the rear section of the hood 50, which cuts the evenly spaced projections 52 at right angles to form a segment of a circle on the cup-shaped hood 50.
  • the hood 50 has between two adjacent projections 52 a wall thickness which corresponds essentially to the cross-sectional thickness of an inner, soft padding 9 of the integral helmet to be lined.
  • the device according to the invention according to the first exemplary embodiment is further supplemented by a sleeve 60 made of an elastic material such as rubber, which is placed on the side of the hood 50 facing away from the body. 2a to 2c, this sheath 60 is a type of second hood which, together with the hood 50, forms an interior or cavity and is already preformed in accordance with a standard head or the dome of the helmet to be adapted.
  • a shock-absorbing lining 8 made of a dimensionally stable material, for example a foamed synthetic resin, on the inside of which there is in turn a soft padding 9 made of an open-pore synthetic resin foam or an air and moisture permeable textile, for example Goretex.
  • An inner channel system for ventilation of the helmet interior is arranged between the soft padding 9 and the dimensionally stable lining 8, which in connection with the air and moisture permeable padding 9 enables air circulation.
  • the inner channel system is formed by a multiplicity of inner flow channels 4 formed in the dimensionally stable liner and distributed substantially over the entire circumference of the liner, some of which open at the front edge of the helmet upper part 1 into a helmet interior between the front half of the face and a visor device 3 and extend substantially parallel to a rear area of the helmet upper part 1, bypassing heavily loaded or deformed areas.
  • the inner flow channels 4 are delimited by a collecting channel 5 which intersects the inner flow channels 4 at right angles to form a segment in the form of a segment of a circle.
  • the collecting duct 5 has in each case a duct connection with at least one air inlet opening 105 which is arranged in the neck region of the helmet upper part 1 and which enables ventilation of the back of the head region within the helmet upper part 1.
  • an outer channel system is provided in the front section of the full-face helmet, which is formed by a number of longitudinally extending, substantially uniformly spaced outer flow channels 6, which become the Open the part on the front edge of the upper helmet part 1 also into the interior between the front half of the face and the visor device 3.
  • the outer flow channels 6 open into an upper area of the helmet upper part 1 into a main air channel 7, which is formed in one piece with the outer partial shell 1 with an air inlet opening 107 oriented towards the front of the full-face helmet and in the mouth area of the outer flow channels 6 between the two partial shells 1 a, 1 b is continued.
  • the lining 8 of the helmet upper part 1 is also provided in the mouth region of the outer flow channels 6 with a number of transverse channels 11, which establish a connection between the inner flow channels 4 and the main air channel 7.
  • the main air duct 7 ends in at least one air outlet opening 207, which is arranged in the rear region of the helmet upper part 1.
  • the air outlet opening 207 which is preferably arranged in a turbulent area of the helmet upper part 1, has a larger overall flow cross section than the air inlet opening 107 of the main air duct 7, which has a cross-sectional constriction in the entire mouth region of the outer flow ducts 6 and the transverse ducts 11.
  • the cross-sectional ratios over the length of the main air duct 7 depend essentially on the total flow cross section of the outer flow ducts 6 and the transverse ducts 11 and can be determined in such a way that a reduction in the dynamic pressure down to a negative pressure region is achieved by increasing the flow velocity in the narrowed mouth region.
  • the at least one rear air inlet opening 105 is provided for the collecting duct 5, via which a possible pressure increase within the helmet upper part 1 can be relaxed.
  • the helmet lower part 2 of the integral helmet is also provided on the inside with a padding 10 which almost seals the helmet interior in the neck and neck area. Furthermore, the lower helmet part 2 is formed in one piece with a chin guard, in which a controllable ventilation device 40 is provided.
  • the ventilation device 40 is formed by a plurality of ventilation slots in the chin guard, which generate a laminar air flow for ventilation and dehumidification of the visor device. The air that has flowed in is then drawn off, as already described, via the outer and inner duct system in the lining 8 of the helmet upper part 1.
  • the ventilation device 40 there is also a microfilter 42 for cleaning and dehumidifying the inflowing air, which is accommodated in an air passage 41 in the front chin guard half.
  • FIG. 6 shows a further embodiment of an integral helmet in which the padding according to the invention can be provided.
  • the at least one outlet opening 207 is integrated in a tear-off edge 16, which is formed over the substantially entire radius of the helmet upper part 1 and generates an artificial flow break to form a turbulent flow zone.

  • the sleeve 60 which is now provided on the inside with projections aligned in accordance with the outer channel system described above, is then drawn onto the still deformable synthetic resin.
  • this second sleeve 60 therefore corresponds to the inverted first hood 50, the channel surrounding the sleeve 60 also being able to be aligned accordingly on the inside of the inverted hood 50. I.e.
  • the ring channels of the hood 50 and the casing 60 can be brought into contact with one another to form a tight seal, so that a lateral escape of the foamed synthetic resin can be prevented. It is of course also possible to design the hood and cover in one piece in their manufacture. In order to achieve an even better fit, the hard outer shell of the helmet upper part 1 is finally pressed onto the outer shell 60 and held there.
  • the helmet upper part 1 is removed and the two hoods 50, 60 are pulled off the finished lining 8.
