- at least one front part comprising an external layer and an internal layer defining a front volume,

- at least one back portion comprising an outer layer and an inner layer defining a back volume,

- At least one protective assembly 29 intended to reinforce the front part or the dorsal part, the protective assembly 29 being received in at least one of the front or back volumes.

The protection assembly 29 comprises a plurality of protection plates 35 integral with one another and fixed to each other in fixing zones 37 provided on said plates 35.

Bumper protection vest

The present invention relates to a bumper protection vest intended to cover at least part of the torso and back of a user, comprising:

- at least one front part comprising an external layer and an internal layer defining a front volume,

- at least one back portion comprising an outer layer and an inner layer defining a back volume,

- at least one protection assembly intended to reinforce the dorsal part or the front part, the protection assembly being received in at least one of the frontal or dorsal volumes.

Such a vest is intended for law enforcement or security personnel, for example.

Such a vest must be able to protect its user against violent blows and in particular those carried by a sharp, perforating or blunt weapon, for example during confrontations in demonstrations, or during an assault when the user is in faction or controls an individual.

Vests of this type known in the prior art generally include a plurality of independent volumes defined by the outer and inner layers of the vest, distributed over the torso and the back of the user. These volumes form insertion pockets capable of receiving rigid protective reinforcement plates. The protective plates of the vest are therefore separated and separated from each other by joining zones such as for example sewing or gluing zones. These joint areas form areas of weakness where the protection of the individual is not ensured. If the weapon is struck in these areas, between the protective plates, the user can be injured. In addition, during an impact between two plates or in the vicinity of an edge of a plate, the plate or plates are liable to move and leave an even larger area of the user's body unprotected.

Furthermore, generally the known vest does not adapt well to the morphology of the user because of the rigidity of the assembly. It generally restricts the freedom of movement of the user. Furthermore, during prolonged wearing of the vest, the edges of the protective plates can injure the user, for example by friction.

One of the aims of the invention is to overcome these drawbacks by proposing a bumper protective vest which provides continuous protection over the entire surface of the vest while providing good freedom of movement and better comfort. 'use.

To this end, the invention relates to a protective vest of the aforementioned type in which the protection assembly comprises a plurality of protective plates integral with each other and fixed together in fixing zones provided on said plates.

Thus, the protective assembly can cover the entire surface of the protective vest ensuring good protection for the user. Furthermore, the plurality of protective plates and the fixing zones between the plates make it possible to provide relative flexibility of the vest and thus improves its comfort of use.

The invention may also include one or more of the characteristics below, considered individually or in any technically possible combination:

- The protection plates are movable relative to each other according to at least one degree of freedom;

- two adjacent protective plates have at least one overlapping zone with respect to the other;

- the fixing zones are located at the level of the overlapping zones;

- The protection assembly comprises at least one shock absorbing cushion secured to the plurality of protection plates;

- The protection plates are connected to each other by a first plurality of straps and in that the protection plates are connected to the shock absorbing cushion by a second plurality of straps;

- the protective plates are made of polymer or aluminum;

- the protective plates are substantially flat;

the protection assembly is removably attached, inside the front volume or the back volume;

- The vest includes a first set of protection received by the front volume and a second set of protection received by the back volume.

In what follows, the term "external" is defined by what is turned towards the outside of the protective vest, that is to say opposite to the part of the body wearing the protective vest, and the term "internal" by that which is turned towards the interior of the equipment, that is to say towards the part of the body carrying the equipment.

The terms "upper", "lower", "left", "right", "transverse" and "longitudinal" are used with reference to the usual directions of the human body.

Other aspects and advantages of the invention will appear on reading the description which follows, given by way of example and made with reference to the appended drawings, among which:

Figures 1 and 2 show an example of a bulletproof protective vest 1 for law enforcement or security personnel, for example. In the following description, the bumper protection vest 1 will be simply referred to as "vest 1".

The vest 1 comprises at least one front part 3 intended to cover at least part of the user's torso and a back part 5 intended to cover at least one part of the user's back.

Each of the front 3 and back 5 parts have an external layer 7 and an internal layer 9 and respectively define a front volume 11 and a back volume 13.

The outer 7 and inner 9 layers are for example formed by a resistant textile material. This material is for example advantageously suitable for the absorption and / or evacuation of the user's sweat and the ventilation of the vest 1 in order to improve its comfort. As a variant or in addition, the outer layer 7 can be flame retardant or hydrophobic.

More particularly, the invention applies to a vest 1, the front part 3 of which is in one piece, that is to say that it does not have a front opening, or as a variant, the front part of which comprises a front opening, for example with a zipper, which would separate the front part 3 into two separate sections.

The front 3 and back 5 parts each have two side parts 15 intended to protect the sides of the user.

The front 3 and back 5 parts are for example fixed to one another in a removable manner. The fixing is done for example by their respective upper parts at the level of the user's shoulders and / or by their lateral parts 15 at each of the user's sides. The upper and / or lateral parts 15 can also serve as means for clamping and adjusting the front 3 and dorsal 5 parts around the body or at the level of the user's shoulders, for example by providing adjustable fixing means making it possible to tighten more or less the parts of the vest around the body.

The fixing is done for example by means of Velcro® type Velcro® straps, snaps or zipper.

As a variant, the front 3 and back 5 parts are fixed to each other in a non-removable manner, for example by sewing. The vest 1 then forms a chasuble which the user puts on by the head.

The front 3 and back 5 assembled together, define a passage for the arms 17 and a passage for the head 19 of the user.

The vest 1 comprises for example lateral fixing and clamping means 21 at the sides which allow the user to adjust the vest 1 to his body size.

These fixing and tightening means 21 are for example carried by the lower and / or lateral part 15 of the front 3 and dorsal 5 parts of the vest 1.

These fixing and tightening means 21 are, for example, straps provided with sliding loops or hook-and-loop straps, of Velcro® type as visible in FIGS. 1 and 2.

As shown in Figures 1 and 2, the vest 1 may further comprise a removable or non-removable neck 23, protective panels for part of the arms 25 fixed for example removably to the vest 1, reinforced by shells 27 made of rigid material in order to improve the protection of the user wearing the vest 1.

According to the invention, the vest 1 comprises at least one protective assembly 29, 31 intended to reinforce the front part 3 or the dorsal part 5. The protective assembly 29, 31 is received in at least one of the front volumes 11 or back 13.

Typically, the vest 1 comprises a first protection assembly 29 received by the front volume 11 and a second protection assembly 31 received by the back volume 13.

Advantageously, the protective assembly 29, 31 is removably fixed, inside the front volume 11 or the back volume 13. The front volume 11 or back 13 then comprises an opening located for example in its lower part.

The protection assembly 29, 31 is for example fixed inside the front or back volume 11 by hook-and-loop tapes 33 located on the upper part of the protection assembly 29, 31 as visible in FIGS. 3 and 4. The protective assembly 29, 31 is then suspended inside the frontal 11 or dorsal volume 13. The suspension of the protective assembly 29, 31 in the frontal 11 or dorsal volume 13 makes it possible to avoid collapse of the protective assembly 29, 31 after a certain period of use, which could occur if the assembly was received loosely in the volume.

As a variant or in addition, the protection assembly 29, 31 is fixed inside the front volume 11 or dorsal volume 13 by fixing zones located on the lateral edges of the protection assembly 29, 31.

In a variant not shown, the attachment of the protection assembly inside the front 11 or back 13 volume comprises at least one of a button, a press button, a zipper.

The removable attachment mode of the protective assembly 29, 31 thus makes it easier to replace it in the event of deterioration and also facilitates the maintenance of the outer 7 and inner 9 layers of the vest 1.

According to the invention, the protection assembly 29, 31 comprises a plurality of protection plates 35 integral with one another and fixed to each other in fixing zones 37 provided on said plates 35 as visible in Figures 3 and 4.

Advantageously, the protective plates 35 are made of rigid material such as, for example, polymer. For example, the protective plates 35 are made of high or medium density polycarbonate.

The thickness of the protective polymer plates 35 is for example between a few millimeters and a centimeter, typically 2 to 4 mm depending on the weight and the degree of protection desired.

As a variant, the protective plates 35 are made of aluminum.

The thickness of the aluminum protection plates 35 is for example between 1 mm and 5 mm, typically 2 to 3 mm.

In another variant, the protective plates 35 are made of any other material which has, such as polycarbonate and aluminum, a high mechanical resistance to the penetration of a stabbing weapon while having a relatively low density, for example less than 3, so as not to weigh down the vest 1.

According to one embodiment, the thickness of the protective plates 35 is different from one protective plate 35 to another.

Thus, certain protective plates 35 located for example in front of sensitive organs of the human body such as the heart or the stomach can advantageously be thicker in order to present a higher resistance.

Advantageously, two adjacent protective plates 35 comprise at least one overlapping zone 39 relative to the other as visible in FIGS. 3 and 4.

The overlapping area 39 is typically a strip which extends along one of the sides of a protective plate and which has a width of between 0.5 cm and 2.5 cm, typically 1.5 cm.

Thus, thanks to the overlapping zones 39 between the protective plates 35, the front 3 and / or dorsal part 5 of the vest 1 which includes the protective assembly 29, 31 according to the invention has no weak areas on which a stabbing could be struck and potentially injured the user. The protection is therefore continuous over the whole of the front 3 or dorsal 5 part comprising the protection assembly 29, 31. Even in the event of displacement of one of the plates 35 under the effect of an impact, the overlap area 39 ensures that the user's body remains protected by the adjacent plate 35.

According to the invention, the protective plates 35 are substantially flat.

They are therefore easy to manufacture, by being cut, for example, using cookie cutters. They therefore do not require the use of specific shaping or molding methods.

According to the invention, the fastening zones 37 of the protective plates 35 between them are located at the level of the overlapping zones 39.

The attachment zones 37 are, for example, stitching, bonding or welding zones.

The fixing zones 37 are advantageously chosen so that the protective plates 35 are movable relative to each other according to at least one degree of freedom.

Thus, the fixing zones 37 allow the various protective plates 35 to be articulated relative to one another according to the movements of the user.

The fixing zones 37 do not cover the whole of an overlapping zone

39. The attachment zones 37 are substantially punctual on the scale of the vest 1 and extend over a distance of, for example, between 0.5 cm and 2 cm, typically cm.

The dimensions of the protective plates 35 as well as the location of the attachment zones 37 of the plates 35 therebetween are advantageously chosen in order to adapt to the human morphology so that the vest 1 best matches the shape of the human body and thus facilitates the natural movements of the user by allowing the plates 35 to slide relative to one another.

Figure 3 shows an exemplary embodiment of a protection assembly 29 intended to reinforce and protect the front part 3 of the user. This protective assembly 29 will be referred to as “frontal assembly 29” in the following description.

The front assembly 29 has a generally substantially polygonal shape comprising a lower edge 41, three right side edges 43A, 43B and 43C, three left side edges 45A, 45B and 45C, a left upper edge 47, a right upper edge 49 and a central upper edge 51.

The central upper edge 51 has a concave curvature so as to match the shape of the neck.

The front assembly 29 is symmetrical with respect to the perpendicular bisector of the lower edge 41.

As visible in FIG. 3, the front assembly 29 comprises an upper part 53, a lower part 55 and two left lateral parts 57 and right 58.

The upper part 53 comprises a central plate 59, a left central plate 61 and a right central plate 63.

The left central plates 61 and right central plates 63 are arranged on either side of the central plate 59.

The central plates 59, left central 61 and right central 63 have a substantially polygonal shape and an elongation axis extending longitudinally.

The upper part 53 also comprises two upper left plates 65 and right 67, also arranged on either side of the central plate 59.

The lateral edges of the central plate 59 each overlap one of the central left 61 and central right 63 plates in the direction of elongation of the plates.

The lower edges 59A, 61A and 63A of each of the central plates 59, left central 61 and right central 63 have a convex curvature whose radius of curvature is identical for each of the plates 59, 61 and 63.

As can be seen in FIG. 3, the upper left 65 and right 67 plates have fixing zones 33 by self-gripping strip intended to fix the front assembly 29 inside the front volume 11 as described above.

The upper left 65 and right 67 plates overlap both the central plate 59 and the left central 61 and right central 63 plates respectively as shown in FIG. 3.

The right upper plate 67 has a fixing zone 37 with the central plate 59 located on the upper edge 51 and a fixing zone 37 with the right central plate 63 located on the lateral edge 43C.

Symmetrically, the upper left plate 65 includes a fixing zone 37 with the central plate 59 located on the upper edge 51 and a fixing zone 37 with the left central plate 61 located on the edge 45C.

The upper part 53 of the front assembly 29 makes it possible to protect the user's thorax and upper part of the abdomen.

The lower part 55 of the front assembly 29 comprises a lower central plate 69 and two lower left plates 71 and lower right 73.

The upper edges 69A, 71A and 73A of the lower central plates 69, lower left 71 and lower right 73 have a concave curvature whose radius of curvature is substantially identical to that of the lower edges 59A, 61A and 63A of the central plates 59, central left 61 and right center 63 of the upper part 53 of the front assembly 29.

The lower central plate 69 overlaps the two lower left plates 71 and lower right 73.

The lower central plate 69 has two fixing zones 37 with the lower left plate 71 and two fixing zones 37 with the lower right plate 73.

The lower part 55 of the front assembly 29 protects the lower part of the user's abdomen.

The lower edge of the upper part 53 of the front assembly 29 overlaps the upper edge of the lower part 55 of the front assembly 29. The upper part 53 is fixed to the lower part 55 at the side fastening zones as visible in Figure 3.

The upper part 53 and the lower part 55 are thus able to move relative to one another so as to enlarge the overlap area. Thus, when the user sits down, the front protection assembly 29 "retracts" and does not interfere with the user at the neck.

Furthermore, the central plates 59, left central 61 and right central 63 of the upper part 53 on the one hand, and the lower central plates 69, lower left 71 and lower right 73 of the lower part 55, on the other hand, are able to move relative to each other in the transverse direction, so as to enlarge the overlapping areas between the plates 35. Thus, the movements of the user's arms are easier, especially when the user brings the arms inward of the body. Thus, the user's arm movements are not hampered, although these can be hampered in the case of protective plates fixed immobile in the vest.

The left side part 57 and the right side part 58 each have a single left side protection plate 70 and right side 72. The respective right and left edges of the plates 70 and 72 are overlapped by the upper part 53 and the lower part 55 of the front assembly 29 and comprises a fixing zone 37 with the upper part 53 and a fixing zone 37 with the lower part 55.

Figure 4 shows an exemplary embodiment of a protection assembly 31 intended to reinforce and protect the back part 5 of the user. This protective assembly 31 will be referred to as "back assembly 31" in the following description.

The back assembly 31 has a generally substantially polygonal shape comprising a lower edge 75, three right lateral edges 77A, 77B and 77C, three left lateral edges 79A, 79B and 79C, two left upper edges 81A and 81 B, two right upper edges 83A and 83B, and a central upper edge 85.

The central upper edge 85 has for example a convex or concave curvature.

As seen in Figure 4, the back assembly 31 includes an upper plate 87, a right upper plate 89, a left upper plate 91, a central plate 93, a lower plate 95, and two left side plates 97 and right side 99 .

The upper 87, central 93 and lower 95 plates have a substantially polygonal shape and an elongation axis extending in the transverse direction. The upper plate 87 overlaps the central plate 93 which itself overlaps the lower plate 95.

The upper plate 87 comprises two fixing zones 37 with the central plate 93 located on the edges 79C and 77C at the level of the overlapping zones. Likewise, the central plate 93 has two fixing zones with the lower plate 95 located at their overlapping zone.

The upper left 91 and right 89 plates respectively overlap a left and right part of the upper plate 87. The upper left 91 and right 89 plates each have two fixing zones 37 with the upper plate 87. The upper left 91 and right 89 plates comprise areas for fixing by self-gripping strip 33 intended to removably fix the back assembly 31 inside the back volume 13 of the vest 1, as described above.

The left lateral 97 and right lateral 99 plates overlap the central 93 and lower 95 plates. The left lateral 97 and right lateral 99 plates each have two fixing zones 37 with the central plate 93 and the lower plate 95 as visible in FIG. 4 .

The relative movement of the plates 35 allows the user to bend down or sit down without the protective assembly 31 hampering his movements.

According to the invention, the protection assembly 29, 31 comprises at least one damping cushion 101 secured to the plurality of protection plates 35, as visible in Figures 5 and 6.

The shock absorber cushion 101 is made of foam, preferably with closed cells. It is for example made of polymer, for example of polyethylene, fireproof for example.

The thickness of the foam lining 101 is for example between 5 mm and 25 mm, typically between 8 mm and 12 mm.

The shock absorber cushion 101 absorbs the shocks received by the user and also prevents the edges of the protective plates 35 from injuring the user.

The shock absorber cushion 101 is either made up of a one-piece plate which covers all of the protection plates 35, or of several independent foam plates which cover each of the protection plates 35 or several protection plates 35.

The shock absorbing cushion 101 may possibly include recesses.

According to the invention, the protection plates 35 of each protection assembly 29, 31 are interconnected by a first plurality of straps (103, 105, 107, 109), (119, 121, 123) and the protection plates 35 are connected to the shock absorber cushion 101 by a second plurality of straps (111, 113, 115, 117), (125, 127, 129).

The straps are for example polyester, nylon or polypropylene.

The straps of the first plurality of straps (103, 105, 107, 109), (119, 121, 123) connect the internal faces of the protective plates 35 and are located between the internal face of the protective plates 35 and the external face of the cushion. shock absorber 101. The straps are not fixed to the protective plates 35 over their entire length but only at the level of fixing zones 116 which have a limited area typically of a few square centimeters as shown in FIGS. 5 and 6.

The fixing zones 116 are, for example, sewing, gluing or welding zones.

The shock absorber cushion 101 has a plurality of sliding passages 118 in which the straps of the second plurality of straps (111, 113, 115, 117), (125, 127, 129) slide. These straps extend transversely or longitudinally over the protection assembly 29, 31, on the internal face of the shock absorber cushion 101 and are fixed at their ends to the protection assembly 29, 31.

At each sliding passage 118, the strap of the second plurality of straps (111, 113, 115, 117), (125, 127, 129) slides under the sliding passage 118.

At the overlapping areas of the straps of the first (103, 105, 107,109), (119, 121, 123) and the second (111, 113, 115, 117), (125, 127, 129) plurality of straps , the strap belonging to the second plurality is slid under the strap belonging to the first plurality.

In FIGS. 5 and 6, the straps (103, 105, 107, 109), (119, 121, 123) of the first plurality of straps connecting the protective plates 35 appear in dotted lines. The straps of the second plurality (111, 113, 115, 117), (125, 127, 129) appear in solid line.

For the front protection assembly 29 (FIG. 5), a first upper transverse strap 103 connects the left upper plate 65, the central plate 59 and the upper right plate 67. A central transverse strap 105 connects the left central plate 61, the central plate 59 and the right central plate 63. A lower transverse strap 107 connects the lower left plate 71, the lower plate 69 and the lower right plate 73.

Finally, a longitudinal strap 109 connects the central plate 59 to the lower plate 69.

The shock absorber cushion 101 is fixed to the protective plates 35 of the front assembly 29 by four straps 111, 113, 115 and 117 which each slide in a sliding passage defined in the shock absorber cushion.

A first transverse strap 111 connects the right edge of the right upper plate 63 to the left edge of the left upper plate 61. A second transverse strap 113 connects the right edge of the right side plate 72 to the left edge of the left side plate 70.

Finally, two longitudinal straps 115 and 117 connect the lower edge of the lower plate 69 respectively to the upper edge of the left upper plate 65 and to the upper edge of the upper right plate 67. The two straps 115 and 117 form a V.

For the back protector assembly 31 (FIG. 6), a transverse strap 119 is fixed to the internal face of the central plate 93. Two longitudinal straps 121 and 123 connect the upper plate 87, the central plate 93 and the lower plate 95 between them

The shock absorber cushion 101 is fixed to the protective plates 35 of the back assembly 31 by three straps 125, 127, and 129 which each slide in at least one sliding passage 118 defined in the shock cushion.

A first transverse strap 125 connects the right edge of the right upper plate 89 to the left edge of the left upper plate 91. A second transverse strap 127 connects the right edge of the right side plate 99 to the left edge of the left side plate 97.

Finally, a longitudinal strap 129 connects the lower edge of the lower plate 95 respectively to the upper edge of the upper plate 87.

Thus, the use of the straps makes it possible both to secure the various protective plates 35 to one another and to secure all of the plates 35 to the damping cushion 101 while retaining the relative degrees of freedom of each of the plates 35, some compared to others.

Thus, the vest 1 according to the invention allows continuous protection over its entire surface and does not have areas of weakness which could be perforated in the event of an attack with a stabbed weapon.

In addition, thanks to the large number of protective plates 35 which compose it and to the advantageous location of the fixing zones 37 between the different plates 35, the vest 1 has a more flexible structure than the vests of the state of the art. The protective plates 35 are articulated relative to each other. This significantly improves the freedom of movement for the user. Furthermore, the vest 1 also adapts more advantageously to the morphology of the user and thus prevents the latter from being injured, for example by the edges of the protective plates 35.

Of course, other embodiments of the invention can be envisaged. Thus, the number of protective plates 35 of the protective assembly and the arrangement of these plates 35 relative to each other can be adapted according to the desired protection.
