Description

The present invention relates to a protective apron of a person against shocks, particularly for people working near animals. People working near animals, such as veterinarians, breeders, breeders of animal species, farriers or any other person working in close contact with animals such as farm animals, regularly incur may be hit by paws, snouts, hooves or tools. In order to be protected against shocks or knocks, it is recommended to wear apron-type protective articles, able to absorb the energy due to shocks or friction and to thus dampen the pressure exerted on a part of the body. For example, a protective apron for farriers is known having a leather portion held around the waist and covering the part of the body below the waist, the leather portion being reinforced with more leather pieces. thick at the wearer's legs. The thickness of the leather parts and their weight are such that the deck is particularly uncomfortable, cumbersome and not very ergonomic. A protection apron for farriers is still known comprising two portions covering the wearer's thighs and knees, joined at the crotch, and each portion of which is reinforced by drop-shaped damping parts made of elastomeric materials. , the whole being covered with leather. This apron makes the movement of the legs easier and particularly facilitates the position on the knees of the wearer. However, this apron does not allow the protection against shock of body regions other than the upper legs. Moreover, the particular shape of the damping parts is such that it is necessary to provide aprons of different sizes depending on the sizes and the body of different carriers. An object of the present invention is to provide an apron for protection against shocks, particularly for people working near animals such as cows, pigs or horses, which is ergonomic, effective to protect all body parts exposed to blows, not bulky and not heavy. To this end, the invention relates to an impact protection apron comprising a lower portion intended to cover a region of the wearer's body below the waist, said lower portion comprising: a support, a set composed of at least two elements of shock-absorbing material disposed on a first face of said support and separated by at least one fold line of said support, said assembly covering the whole of a first face of said support. Advantageously, each element extends from one edge to the other of said portion. Advantageously, the apron comprises an outer envelope which covers said assembly and which is fixed on the first face of said support by junction points made between two adjacent elements in the fold lines, each fold line extending from one edge to another of said portion. According to one embodiment of the invention, each element of shock-absorbing material has the shape of a rectangular parallelepiped. Advantageously, the junction lines form rotational axes around which the elements of adjacent shock-absorbing material are movable.

Advantageously, the width of the space separating two elements of shock-absorbing material is substantially equal to the width of the junction points. According to one embodiment, each element of shock-absorbing material is composed of a polymer foam having a compressive strength of 25% between 40 and 95 KPa, preferably between 40 and 60 KPa, more preferably between 44 and 56 KPa. Preferably, the polymer foam has a density of between 30 and 80 kg / m 3, a thickness of between 80 and 100 mm. Also preferably, the polymer foam is selected from expanded polystyrene, closed cell polyethylene foam, closed cell polyurethane foam. Advantageously, the outer envelope is a woven fabric having a breaking strength greater than 250 daN / 5cm. Preferably, the outer envelope is a polyester fiber fabric or a blend of polyester and polyurethane fibers.

According to one embodiment, the second face of said support is covered with an inner envelope intended to be applied against the wearer. Advantageously, the length of the lower and upper edges is at least 100 cm, preferably at least 120 cm.

Advantageously, the apron according to the invention comprises belt straps interconnected by a connecting means for holding the apron around the size of the wearer, each belt strap comprising means for adjusting the length.

Advantageously, the apron further comprises a holding means in a folded position in which the lateral edges of the lower portion are folded on themselves on the same side.

The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description of exemplary embodiments, said description being given in relation to the figures of which: FIG. 1, in which is illustrated an impact protection apron according to a first embodiment of the invention, FIG. 2, in which is shown a cross-sectional view of an impact protection apron according to one embodiment of the invention, FIG. 3, schematically depicting a crash shield in a folded position, according to an embodiment of the invention, FIG. 4, on which is illustrated an impact protection apron according to one embodiment of the invention, FIG. 5, on which is illustrated an apron for protection against shocks according to a second embodiment of the invention.

An apron 1 for protection against shocks is shown in FIG. 1, carried by a carrier P. The apron 1 comprises a lower portion 2 for covering the region of the body of the carrier P located below the size ST. The lower portion 2 has an upper edge 21 and a lower edge 22. The upper edge 21 is intended to be applied against the carrier P at its waist. The apron 1 has, in addition, an upper portion 15 for covering the region above the size DT of the wearer, including the belly and the chest. The lower edge 151 of the upper portion 15 intended to cover the region of the wearer's body above the size DT and the upper edge 21 of the lower portion 2 intended to cover the region below the size ST of the wearer are combined. . In a variant of the invention which is not described but nevertheless envisaged in the context of the present invention, the apron 1 comprises only a lower portion 2. In FIG. 2 is a sectional view of the lower portion 2. The latter 15 comprises a support 3, non-rigid and flexible, which may be a needle-punched nonwoven fabric material, for example made of polypropylene fibers. The material of the support 3 is chosen to have good properties of tensile strength, perforation and deformation. By way of example, the textile sold by the company Landolt France SAS under the trade name ACM 300 (weight per unit area: 300 g / m2, 20 thickness at 21 (Pa: 3 mm, tensile strength SP: 12.0 kN / m, tensile strength ST: 15.0 kN / m, maximum tensile stress strain SP and ST: greater than 50, static CBR puncture resistance: 2.5 kN, dynamic puncture resistance: 8 mm, filtration opening: 77 micrometers) is suitable for the realization of the support 3.

On a first face 31 of the support 3, which is the outwardly facing face when the apron 1 is worn, is disposed an assembly 4 composed of elements of shock-absorbing material, at least two, such as the elements 41. and 42. Each element, such as the element 41 or 42, has a surface, such as the surface 41a or 42a, in contact with the support 3. The elements 41, 42 advantageously have the shape of a rectangular parallelepiped. The elements 41, 42 are separated from each other by fold lines 6 of the support 3 as explained in the following. In the embodiment illustrated in FIG. 1, the shock-absorbing elements 41, 42 are arranged in such a way that each fold line 6 is perpendicular to the upper edge 21. It is quite possible, in a variant of the invention, to arrange the shock absorbing elements 41, 42 in lines parallel to the upper edge 21. Each element 41, 42 extends from the upper edge 21 to the lower edge 22 of the portion 2 of in order to cover the lower portion 2 in the longitudinal direction. In addition, the elements, for example 41, 42, forming the assembly 4, are distributed side by side, from the lateral edge 18 to the lateral edge 20 of the region 2 so as to cover the lower portion 2 in the transverse direction (FIG. 4). The assembly 4 thus covers the whole of the first face 31 of said support 3. The number of elements 41, 42 necessary to cover the surface 3 is therefore a function in particular of the dimensions of each element 41, 42. The lengths of the edges 21 , 22 are preferably identical and are at least 100 cm, advantageously at least 120 cm. The lateral edges 18, 20 have a length of between 70 cm and 120 cm, preferably between 80 and 90 cm. As a result, the apron 1 is able to circumvent and wrap the body part including the hips, knees and thighs of the wearer P so as to protect him not only when he faces a source of shock such as a animal, but also when presenting his profile. In a variant of the invention, the shock-absorbing elements will have a cylindrical section. In another variant of the invention, they will have a half-cylinder section, their planar face being disposed against the support 3. Each element 41, 42 is composed of a closed-cell polyethylene foam. It may be closed-cell crosslinked polyethylene foam marketed by Celso SAS having the following characteristics: thickness of at least 85 mm, density 48 +/- 6 kg / m3, lower cell size or equal to 0.35 mm; tensile strength 306 kPa; lengthening: 346%; 10% compression strength: 29 kPa, 25% compressive strength: 44 kPa, 50% compressive strength: 95 kPa; compression persistence (22 h load at 23 ° C, 25% compression): 30 min after discharge: 12% and 24h after discharge: 4%; water absorption (28 days): 1% Vol maximum; hardness 30 Shore: 47 Shore (00). Other materials known to have good energy absorption characteristics resulting from a blow or shock are of course envisaged to enter the composition of the shock absorbing elements. Such materials will advantageously have a compressive strength of 25% between 40 and 95 KPa, preferably between 40 and 60 KPa, more preferably between 44 and 56 KPa. The apron 1 has an outer envelope 5 (FIG 2). The outer envelope 5 is visible when the apron is carried by the carrier P. This outer envelope 5 5 covers the assembly 4. It is fixed on the first face 31 of the support 3 by junction points 61 formed in the lines of folds 6 arranged in a space 7 separating two adjacent elements 41, 42 between them. The junction points 61 form junction lines which coincide with the fold lines 6. Each fold line 6 extends from the upper edge 21 to the lower edge 22 of the lower portion 2.

In the embodiment described in FIG. 2, the junction points are stitches, such as straight stitches or back stitches, the joining lines thus forming seam lines. The fold lines 6 formed of junction points, for example stitching, allow to keep perfectly in place the damping elements 41, 42 against the support 3, especially when an impact is received on one of them. The face 31 of the support 3 which is not smooth because of the component materials also participates in their retention in place. It is therefore not necessary to bond the surface 41a, 42a of the elements 41, 42 to the face 31. Each fold line forms an axis of rotation about which each adjacent shock absorbing member 20 is movable. In the embodiment illustrated in FIG. 3, when the surface of the support 3 is flat, the junction points 61 are substantially in the same plane as the surfaces 41a, 42a of the shock absorbing elements 41, 42 resting against the support 3. The width L1 of the space 7 separating two shock absorbing material elements 41, 42 is substantially equal to the width L2 of the junction points 61. In the expression "substantially equal" it should be understood that the thickness of the outer envelope 5 is taken into account. in the measurement of the width L1. The outer envelope 5 is made of a fabric having a tensile strength greater than 250 daN / 5cm. This fabric must also have good resistance to abrasion, UV, penetration of water. This is, for example, a polyester fiber fabric or a blend of polyester and polyurethane fibers. By way of example, this is the fabric manufactured by Diatex SAS under the reference M18810PS / PU. This fabric has a warp and a weft each composed of 70% polyester and 30% polyurethane (elasticity of the warp: 3024644 7 27%, elasticity of the weft: 42%, air permeability: 0 1 / m2 thickness: 800 microns, tear strength of the warp: 23.5 daN, tear resistance of the weft: 19.8 daN, abrasion resistance (NF EN ISO 12947-2): 40 000 cycles, lightfastness (NF EN ISO 105 B02 standard): greater than 6, resistance to penetration of water: greater than 1000 cm of water height). The apron 1 has an inner envelope 8 (FIG 2). The inner casing 8 is intended to be applied against the wearer P when the apron is worn. It is fixed, for example by gluing or seaming on the face 32 of the support 3, opposite to the surface 31. It may be a fabric also having good characteristics of resistance to tearing and breaking. . The lower portion 15 is advantageously composed of a support covered with an outer envelope identical to the outer envelope 5 and an inner envelope identical to the inner envelope 8 which have been described in connection with the lower portion 2. It can also be provided that this upper portion 15 comprises shock absorbing elements such as the elements 41, 42 which have been described in connection with the lower portion 2. In FIG. 3, is shown an apron 1 in a folding or storage position (see arrows). The junction lines separating the shock-absorbing elements 41, 42 advantageously form fold lines 6 in which a shock-absorbing element, for example the element 41, can form an angle (a) with a shock-absorbing element. , for example the element 42. It is thus possible to fold the apron 1 so that the side edges 27 and 28 of the lower portion 2 are folded or rolled on themselves on the same side. A holding means 26, composed for example of one or more strips comprising hooks 25 and one or more strips comprising loops, of the Velcro® type, are provided and are fixed by one of their ends to the outer envelope 5. In this storage position or folded, the upper portion 15 is housed inside the folded apron, against the outer shell 8. One or more gripping handles may be provided.

In FIG. 4 is shown an apron 1 according to the invention, of the type described in connection with FIGS. 1 to 3 above, comprising belt straps 9 and 10 and a pair of straps 16 and 17 for holding to cross in the back of the wearer.

The belt straps 9, 10 are fixed for example by stitching points along the upper edge 21 of the lower portion 2. The belt straps allow the maintenance of the apron 1 around the size of the wearer. They are interconnected by a connecting means, for example of the loop type, comprising a female part 12 provided with a housing for receiving a male part 11, the male part being provided with a tongue intended to come snap into the housing of the female part 12 to ensure the closure of the system. Such a connecting means is well known to those skilled in the art. In addition, each belt strap 9, 10 comprises means for adjusting its length 13, 14.

The holding straps 16, 17 are intended to cross in the back of the wearer, so as to allow the support of the apron 1 on the shoulders of the wearer. A first strap 17 extends from a right lateral edge 18 of the lower portion 2 to an upper left corner 19 of the upper portion 15. A second strap 16 extends from a left lateral edge 20 of the lower portion 2 up to an upper right corner 21 of the upper portion 15. Fastening means 22, 23 are provided, for example at the side edges 18, 20 or at the right and left corners 21, 19, of portion 15. These attachment means are advantageously of the type called loop described above. In addition, each strap 16, 17 includes means for adjusting its length 24, 25.

In a variant of the invention, shown in connection with FIG. 5, the elements 41, 42 are composed of sub-elements 410, 411, 412 and 420, 421, 422, respectively. The sub-elements 410, 411, 412 form the element 41 which extends from the upper edge 21 to the lower edge 22. According to this variant of the invention, the outer envelope 5 is connected to the support 3 along lines of junctions and bend 25 6 extending from the upper edge 21 to the lower edge 22 and the side edge 18 to the side edge 20.
