Definitions

  • the present disclosure relates to a material for a protective suit, such as a motorcycle protective suit.
  • the disclosure also relates to a motorcycle protective suit comprising such a material.
  • motorcycle protective suits are known in the art.
  • the most widely used protection suits are made from leather. It provides a considerably better protection than normal street clothing during a road surface impact. Designing leather suits to provide sufficient protection means using thick layers of specialist leather which makes the suits quite heavy. For this reason suits made from man-made materials have been developed.
  • these suits comprise a protective material comprising a plurality of layers combined to achieve the desired properties.
  • a protective material for protective clothing comprising a plurality of layers.
  • the layers are made from different man-made materials such as for example polyaramid-based materials (such as e.g. Kevlar ® ) and polyurethane-based materials.
  • Other man-made materials known in the art comprises polyamide-based materials (such as Cordura ® ) and polytetrafluoroethylene-based materials (such as Rastex ® ).
  • a material for a protective suit such as a motorcycle protective suit
  • the material comprising: two or more layers, said layers being non-laminated, wherein each layer comprises stretch portions and non-stretch portions, the stretch portions of the two or more layers being arranged to overlap each other, and wherein the two or more layers are locally attached to each other at a plurality or all of the stretch portions, and wherein the material comprises at least one portion wherein the non- stretch portions of the two or more layers are arranged to overlap each other and the two or more layers are locally attached to each other at all of the stretch portions.
  • the two or more layers are not laminated.
  • the non-stretch portions are not laminated.
  • the stretch portions are also not laminated. It may be noted that at the local attachment, the stretch portions may be locally attached to each other using a technology used for lamination, but they are as mentioned not laminated over the whole extent of the stretch portions.
  • the fact that the layers are not laminated but rather locally attached to each other at the stretch portions implies that the two or more layers are movable with respect to each other between the points of local attachment. As the layers may be free to move with respect to each other, they may - if the material is used in a motorcycle protective suit - more easily follow the shape of the body of the user. This may be used to increase the flexibility of the suit and provide an easier movement of the user, which will improve the comfort for the user compared to the prior art designs.
  • non-laminated layers is advantageous as it may allow using thicker layers to increase the level of protection without introducing discomfort for the user. Using non-laminated layers may further allow using more layers without introducing discomfort for the user.
  • Hard protective gear such as armors and pads for protecting exposed or more vital parts of the body are important parts of the overall protection for a motorcyclist.
  • the hard protective gears are typically worn inside the suit close to the body. During an accident there may be a risk of such hard protective gear to become misaligned from their intended position as a result from impact. This misalignment may be prevented, or at least alleviated by the use of a protective suit with a tight fit to the body of the user.
  • motorcycle protective suits of the art are not tailored to be tightly fit to the user to the extent required. One reason for this is that a tight fit of prior art protective suits typically increase the discomfort of the user.
  • the use of non-laminated layers may allow tailoring a protective suit to more tightly fit the body of the user that still is comfortable to use, which in turn will provide a more correct and secure positioning of the hard protective gear.
  • the material may comprise a portion at which each of the two or more layers comprises a sequence of a first stretch portion followed by a first non-stretch portion followed by a second stretch portion, wherein the first stretch portions of the two or more layers overlap each other, wherein the first non-stretch portions of the two or more layers overlap each other, wherein the second stretch portions of the two or more layers overlap each other, and wherein all the layers are locally attached to each other at the overlapping first stretch portions and at the overlapping second stretch portions.
  • This may be an advantage as it may achieve an improved fit of the material when used for example as a protective suit. Specifically, no stretch portion will overlap a non-stretch portion. Thus, the protective functionality of the non-stretch portions may be used to its full extent. By allowing each of the two or more layers to have the same spatial distribution of stretch and non-stretch portions in relation to its neighboring layers, the degree of overlap will improve also in situations where the material is exposed to a high degree of tension.
  • the second stretch portion may in the sequence be followed by a second non- stretch portion followed by a third stretch portion, wherein the second non-stretch portions of the two or more layers may overlap each other, wherein the third stretch portions of the two or more layers may overlap each other, and wherein all the layers may be locally attached to each other also at the overlapping third stretch portions.
  • the local attachment may be positioned in the central part of the stretch portions such as to allow the two or more layers to move freely with respect to each other at the peripheral parts of the stretch portions. This provides an increased degree of freedom for the two or more layers to move independently of each other, and may thus be utilized to increase the comfort of the user.
  • Each of the two or more layers, at their non-stretch portions, may comprise a fabric having an in-plane Young's modulus between 5 and 200 GPa along at least one direction in the plane.
  • Each of the two or more layers, at their non-stretch portions, may comprise, and may more preferably as a major constituent comprise SuperFabric, Cordura, or Kevlar Fabric, or a combination thereof.
  • the outermost layer may comprise, and may more preferably as a major constituent comprise, SuperFabric and the innermost layer may comprise, and may more preferably as a major constituent comprise, Kevlar Fabric.
  • SuperFabric may be advantageous, preferably as an outer layer, as it may provide a high resistance to abrasion, tears and cuts while, at the same time, being sufficiently breathable.
  • Cordura may be advantageous as may provide water resistance, high durability and sufficient breathability.
  • Kevlar Fabric may be advantageous, preferably as an inner layer, as it may provide high durability and sufficient breathability. Moreover, Kevlar Fabric may decrease heat conduction. This is an advantage as it allows for protecting a user exposed to high degree of heat, for example during an accident. The heat could for example be frictional heat when sliding on a road surface, heat due to fire, or direct contact with hot engine parts such as for example the exhaust pipe of a motorcycle.
  • the two or more layers may, at its stretch portions, comprise a fabric having an in- plane Young's modulus between 0.5 and 100 MPa along at least one direction in the plane.
  • the two or more layers may, at its stretch portions, comprise, and may more preferably as a major constituent comprise, Kevlar Stretch.
  • the two or more layers may, at its stretch portions, comprise, and may more preferably as a major constituent comprise, SuperFabric Stretch.
  • stretch portions and the non-stretch portions of each of the two or more layers may be attached to each other by adhesion, riveting or sewing, preferably by sewing.
  • the two or more layers may be locally attached to each other by adhesion, riveting or sewing, preferably by sewing.
  • the use of two or more layers is advantageous as it allows for increasing the strength of the material. For example, the total strength of the attachments between stretch portions and non-stretch portions will increase. This may provide a higher protection for a user.
  • the two or more layers may be locally attached to each other by sewing a plurality of seams, preferably three or more seams alongside each other, as counted from a non- stretch portion to an adjacent non-stretch portion.
