Definitions

  • the present invention relates to work and safety clothing comprising integrated protection against accidents, in particular those caused by chainsaws or more generally those caused by tools.
  • these are mainly those of a first type which aim to obtain a delay effect on the penetrating action of the chainsaw chain to allow the user to stop the engine or discard said chain, and those of a second type which aim to block the chain of the chainsaw.
  • Those of the first type are generally constituted by a thick mattress of fabrics through which the progression of the chain is slowed down.
  • Those of the second type are generally constituted by a superposition of pieces of fabric in superimposed layers assembled together and capable of detaching completely or partially one after the other, under the traction of the chain to come to engage between the pinion and the chain and block the movement of the latter.
  • This protection consists of a superposition of parts of fabric, preferably synthetic, some of which have the effect of sliding the chain and others are tear-off to block said chain saw chain.
  • the tear-off parts are fixed to the other parts by elastic members capable of breaking under traction.
  • Canadian patent THERIAULT n ° 1.015.504 describes a protection against the attack of chainsaw chains which combines thicknesses of fabrics with resistant fiber and at least a thickness of thin and sliding fabric on which the chain of the chainsaw as stated in the description of said patent will slide.
  • This design has the drawback in allowing the chain to slide to make it possible to lose control of the chainsaw, which by its weight combined with the speed of rotation of the chain is endowed with significant potential inertia by the user.
  • the principle underlying the production of the garment according to the invention is that it must be and remain comfortable and effective for the user throughout its lifetime, that is to say until the accident which deteriorates protection.
  • Another principle is that the garment must be light, compact and easy to don or remove while providing maximum protection.
  • Another principle is that the garment with its protective parts and the integration of one with the other must be simple and inexpensive.
  • the objective of the invention is to make a work garment with integrated protection constituted in a known manner of several layers of fabrics, the said layers being fixed to each other by means designed and combined together so that, on the one hand, there is no realization of significant extra thickness and that on the other hand, there is not a cutting of layers but their stretching, distortion and tearing which contributes first of all because of the structure of the layers to engage the gongs in the wires, then to brake the chain and finally by tearing off the first layer, its arrival at the drive sprocket of the chain and if necessary the other layers, block the drive of the chain, either by making it clear of the sprocket, or by stalling the engine .
  • the work clothing according to the invention comprising at least one integrated protection constituted by a superposition of layers of fabrics, this protection being fixed to the fabrics of the clothing is essentially characterized in that for each protection of the superimposed layers of protective fabrics are made up of parts of the same size which are joined by their periphery, on the one hand by means of seams transverse to their selvedges and on the other hand, by seams parallel to said selvedges and set back from the preceding ones, that these seams for fixing the parts to each other are combined with seams transverse to the protection, parallel to each other which assu- "rent maintaining different layers therebetween, and these fastening seams and held in position between parts are combined with the protection attachment seams, the fabric of the garment, these latter seams being formed parallel to the edges near the other seams.
  • the layers of protective fabrics are joined by their periphery by means of overcasting seams with overlock stitch set back from the overcasting, these seams are always combined with transverse seams for holding the pieces in position together and always combined with the securing seams of the protection thus formed to the fabric of the garment.
  • seams ensure a permanent fixation of the different your layers between them on the one hand, and protection to the garment on the other hand, as long as the protection is not attacked by the chain of the chainsaw.
  • the method of fixing the layers to each other on the one hand, and of the protection to the garment on the other hand allows the edges to be tightly pressed against each other and on the garment, which makes it possible to avoid uncomfortable extra thicknesses.
  • the protections are fixed as close as possible to the joining seams of the panels together which constitute the garment, jacket or pants, which increases protection and comfort.
  • the transverse and parallel seams for assembling the parts together are seams, transverse to the direction of the chain of protection, made along broken or wavy lines having a succession of angles protruding and re-entrant, which allow the layers to remain homogeneous but which promote their successive tearing off when the protection is attacked by the chain of the chainsaw.
  • the protective element consists of an upper envelope which comes against the internal face of the fabric of the garment and a lower envelope between which are placed layers of a woven synthetic material, with weft and warp, having high characteristics and resistance to cutting and traction and at least one layer of a woven or nonwoven fabric of aromatic polyamide aramid known commercially under the name of KEVLAR Preferably the layer of KEVLAR is placed on the lower envelope.
  • the garment according to the invention comprises pants 1 and a jacket 2 on which the protections 3 are represented by hatched areas, but it goes without saying that the said garment can have any other configuration.
  • the protections are mounted on the internal face of the garment on the particularly sensitive parts, that is to say the legs for the pants, preferably from the groin to the ankles, the sleeves , chest and shoulders for the jacket.
  • Each of the protective elements of different shape depending on the panel of the garment to which it must be adapted consists of the following manner (see Figure 2).
  • the walls 4 and 5 are of the same dimensions.
  • layers 6 superimposed of a fabric of a woven or nonwoven synthetic material having high characteristics of elasticity and resistance to cutting and traction.
  • the successive layers of materials can be of the same nature or of a different nature both in terms of their composition, their structure, their weave, their texture, weight and modulus of resistance.
  • the successive layers are made of a synthetic material woven according to a weave of the ETAMINE "canvas" type having a thread above and a thread below in an airy texture, for example of a value of seven to eight threads per square centimeter, the weft and warp threads being capable of being spaced apart to let the gongened links of the chain engage between them.
  • each layer 6 has a texture in the warp direction of the protection equal to 7.3 and in the weft direction a texture equal to 8.2.
  • the yarns making up each layer are made of continuous polyester and the decitex index of the yarn used is 1100 and they are formed by 210 strands assembled together with a twist to the left of 60 turns per meter, while the mass of the fabric at a2 is of 250 grams for a resistance of 850 Kgs at break.
  • chain direction of protection is parallel to the axis of the member to be protected.
  • the layers 6 of fabric are of the same dimensions as the envelope walls 4/5.
  • All of the superimposed layers 6 including the envelope 4/5 are joined by their periphery by means of a succession of seams arranged from the edges of the element inwards, these seams being assembly seams of the layers of the item and stitching securing the item to the fabric of the garment.
  • the selvedges of the layers of fabric are joined edge to edge and around the entire periphery by a transverse seam 7 produced by overcasting.
  • an overlock stitch 8 is made parallel to the selvedges around the entire periphery of the element.
  • Crosswise between the edges of the protective element are made regularly spaced seams or stitching 9, for example fifteen centimeters which are made transversely to the warp direction of the layers 6 of fabric with a thread also with a precise breaking point which allows a normal maintenance of the layers in position and which also allows their successive tearing by breaking of the wires, during the traction of the chainsaw chain.
  • these assembly bites are produced along a wavy or broken line having salient and re-entrant angles.
  • At least one other seam 10 for fixing the element is made between the overcasting and the seam of the overlock and set back from the edge of the layers of fabric over the entire periphery of the element .
  • this seam is made a few millimeters, for example 5 mm, from the edge of the layers of fabric in order to prevent it from escaping from the seam and from the position which is given to them, which would moreover make a uncomfortable thickness.
  • a second seam 11 is made parallel to the seam 10 and set back inward from the seam of the overlock with a spacing relative to the seam 10 of the order of 8 mm.
  • This seam 11 also has, like the seam 10, the function of fixing the protective element to the fabric of the garment and also of helping to maintain the layers of fabric in position.
  • the envelope 5 consists of a fabric composed of approximately 65% of polyester and 35% of cotton and the envelope 4 consists of a polyamide mesh fabric.
  • the protective element in addition to the envelope walls 4-5 comprises five layers 6 of fabric such as mentioned above, consisting of continuous polyester woven yarns, plus an ultimate layer 12, before the inner envelope wall 5, (in contact with the user) made of a KEVLAR fleece mounted on a KEVLAR knitting.
  • the protective element is of identical composition to the example of Figure 2-2 but includes instead of the layer of fleece KEVLAR 12 a layer 13 of KEVLAR woven warp and weft.
  • This layer of KEVLAR woven warp and weft is predominant in the blocking phase of the warp thanks to the very high resistance of this material to breaking and cutting of threads.
  • this KEVLAR is woven in a weave type canvas with thread above and thread below and it is textured comprising about 7 threads in warp and weft per cm2, therefore relatively airy.
  • the DECITEX index of the thread used is 1670 and the mass of the fabric per m2 is 250 greases for a resistance of 850 kgs.
  • the protective element comprises in superposition, a layer 12 of KEVLAR fleece and a layer 13 of warp and weft fabric KEVLAR.
  • KEVLAR can be placed, either first, last, or intermediate.
  • the protective elements have substantially the same shape as the panel of the garment to which they adapt and each is fixed to said panel closest to the edges and stitching of the assembly. this one.
  • the layers of fabric then undergo a traction which successively breaks their peripheral seams and very quickly causes one or more layers until engagement between the pinion and the chain which has the effect of blocking the latter in a very short time (a few hundredths of seconds) without the chain having time to cut through the layers.
  • the garment produced is particularly light and comfortable to wear.
  • This process consists first of all of unrolling strips of fabric intended to constitute the different layers of protection.
  • the seams 9 are formed, these seams being formed in the warp direction of the fabric strip.
  • the protection is cut in the mattress so that its greatest length develops transversely to the longitudinal axis of the latter.
  • warp direction of the protection corresponds to the weft direction of the mattress or to the weft direction of the strips of fabric constituting this mattress and the texture in the warp direction, of the layers of fabric constituting the protection will correspond to the texture in the weft direction of the strips of fabric constituting the mattress.
