Definitions

  • the invention relates to a shock absorber with a shock-absorbing structure made of a plastic material.
  • shock absorbing structures are therefore used, for example, as insoles made of gel for shoes or for the protection of body parts during exercise. Due to the flexible properties of the gel material, such impact-absorbing structures are particularly suitable for exhibiting a shock-absorbing effect in the region of joints, without the mobility or freedom of movement of the joint being restricted or unduly impaired.
  • the impact-absorbing effect of such structures made of the commonly used plastic materials is often not sufficient, for example, to be able to form an effective impact protection for motorcyclist clothing.
  • the structure of plastic or gel material would have such a large thickness or material thickness that the protector has an undesirably high weight and barely at the same time can be flexible.
  • the usual protectors for use in motorcyclist's clothing therefore have integrally formed or consisting of several interconnected segments hardshells, which are surrounded on one side or both sides with a suitable shock absorbing material such as foamed polystyrene.
  • these protectors are not or only limited flexibility, so that on the one hand an improved shock-absorbing effect can be achieved with low weight of the protector, however, on the other hand, the wearing comfort is often significantly limited.
  • Object of the present invention is therefore to provide a shock absorber of the type mentioned in such a way that the simplest and most flexible shock absorber can be produced, which can simultaneously have the largest possible shock-absorbing effect.
  • Spacer fabrics are known, for example, in connection with garments.
  • the spacer fabrics are often made of plastic or Natural fibers produced.
  • the known spacer knitted fabrics are preferably used to fill a given volume with a flexible and as light as possible material so that the originally given shape is maintained as far as possible and a voluminous overall impression is produced.
  • a filled up with a spacer knit volume largely retains its insulating effect even with the deformations or strains usually occurring in garments.
  • the known spacer knitted fabrics have only a low compressive strength and therefore no appreciable impact-absorbing effect. This is essentially due to the fact that the individual fibers of the spacer knit fabric under pressure can change their position and orientation according to the applied force, without a significant counterforce or restoring effect occurring, or could be generated.
  • the individual fibers of the spacer fabric are largely fixed in their position and can escape in the case of a sudden pressure load only with a corresponding local deformation of the plastic material, or their position and orientation depending on the occurring Change impact load.
  • the spacer fabric thus acts as a support structure within the plastic material which absorbs the impact energy and distributes it over a larger area of the plastic material, the embedded spacer fabric and thus the shock absorbing structure remain largely flexible.
  • the impact-absorbing effect of the known plastic materials is surprisingly considerably increased by the embedded spacer fabric.
  • the plastic material is a gel material. Suitable gel materials can be easily and inexpensively prepared and processed with the spacer fabric. It is also conceivable and particularly advantageous for corresponding requirements when the plastic material is a plastic foam. A plastic foam is usually very light, without him regularly missing almost any shock-absorbing effect of the embedded spacer fabric.
  • the spacer knitted fabric has spacer elements aligned substantially parallel to a probable thrust direction.
  • the spacers may be, for example, short fibers or fiber sections.
  • the impact-absorbing structure is, for example, a substantially flat layer or a planar gel cushion with a spacer fabric oriented preferably in the layer plane or parallel to the surface of the gel cushion. The individual fibers or fiber elements are then advantageously aligned perpendicular to the layer plane, or to the surface of the gel pad.
  • the layered structure or the gel pad can then perpendicular to the layer plane, ie in the direction of the Substantially absorb shocks occurring essentially parallel to one another.
  • the gel layers or gel cushions can easily be integrated or incorporated into garments so that the individual fibers of the spacer fabric can point outwards and absorb shocks acting on the outside.
  • the spacer fabric has short fibers which are arranged between two outer layers of a textile material.
  • the two outer layers are expediently as well as the spacer knitted fabric as a whole permeable to money.
  • the predominantly oriented perpendicular to the two outer layers short fibers are fixed at both ends of the respective associated cover layer of a textile material in the respective position and orientation.
  • the two cover layers create a composite effect within the plastic or gel material, so that in a sudden local shock load beyond the local area of the shock load extending deformation of the gel material is enforced with the embedded spacer fabric, so that due to the energy required for this efficient shock absorbing effect is generated.
  • cover layers or the support layer can also be an example reticular structure of a plastic or of a natural material, or have a composite material.
  • a shock absorber can be produced easily and inexpensively, and at the same time a long durability and high impact absorption effect can be achieved when the plastic material is a polyurethane gel.
  • other gel materials are conceivable and differently suited according to their respective properties with regard to the various requirements.
  • shock-absorbing effect prescribed, for example, in connection with motorcyclist clothing can already be achieved by virtue of the fact that the shock-absorbing structure has a thickness of less than 10 mm, preferably less than 7 mm.
  • the currently available and known from practice shock absorber usually have a thickness of at least 15 mm to 20 mm in order to ensure a comparable shock absorbing effect.
  • the known shock absorbers but not flexible and thus lead to a significant impairment of wearing comfort.
  • shock-absorbing structure is provided in the shock-absorbing structure.
  • air inclusions can be embedded in the gel material in addition or, at least in regions, even in place of the spacer fabric in the shock-absorbing structure.
  • the invention also relates to a protective garment having at least one shock absorber with the features according to the invention described above, wherein the shock absorber is permanently connected to the protective garment in an impact region of the body.
  • the shock absorber can be embedded, for example, between two layers of a multi-layer protective garment. It is also conceivable that the shock absorber is glued to the protective garment, welded or sewn.
  • trouser-shaped protective garment 1 knee areas 2 often exposed and accident-prone areas of a motorcyclist not shown there, which should therefore be protected as effectively as possible.
  • the protective garment 1 is deformed in the region of the knee areas 2 in almost every leg movement of the motorcyclist, so that the protective garment 1 should have as much flexibility as possible, especially in the knee areas 2.
  • a shock absorber 3 is arranged in each of the two knee regions 2.
  • the shock absorber 3 has a planar, cushion-shaped shock-absorbing structure 4 made of a gel material.
  • the gel material used is a polyurethane gel.
  • a spacer fabric 5 is embedded, as it also made FIG. 2 is apparent.
  • the spacer fabric 5 has two cover layers 6 of a textile material arranged essentially parallel to one another. Between the two cover layers 6 of textile material is a large number of perpendicular to the two cover layers 6 aligned spacers 7.
  • the spacer elements. 7 each consist of short fibers that can be made either of a plastic material or of a natural fiber material.
  • the shock absorber 3 shown schematically in the figures has a thickness of about 6 to 8 mm.
  • the shock absorber 3 is arranged in the embodiment shown schematically in the figures between two layers 8, 9 of the protective clothing piece 1.
  • the two layers 8, 9 expediently consist of a tear-resistant and abrasion-resistant textile material.
  • the shock absorber 3 is glued to the one layer 8, or welded and is thereby fixed in its position within the protective clothing piece 1. Since the shock absorber 3 is extremely flexible and has a small thickness of less than 10 mm, the shock absorber 3 can be integrated into the protective garment 1 without appreciably affecting the wearing comfort in the knee region 2 and reliably protects the knee region 2 from shocks and injuries caused by Impacts against other objects are caused.
