Abstract

A protective vest for use by police and similar forces is placed under the normal clothes, as in the Parent patent. Between the inner and outer envelopes there is a stuffing of felt threaded with polymer fibre. The thickness of the stuffing is between 6-8mm, wt. of is 400-500 g/m2 and tension strength is 22.65 kg/f lengthwise and 21.10 kg/f in width direction. Flame resistance, to standard 07113 AFNOR, is 12.0 lengthwise and 16.5 in width direction. The change gives greater protection against missiles and fire compared with the original stuffing.

Description

La présente addition concerne un gilet parecoups d'intervention selon le brevet principal 76 35 266 du 15
Novembre 1976.
The present addition relates to a life jacket intervention according to main patent 76 35 266 of 15
November 1976.

Dans le brevet principal on a décrit un gilet pare-coups d'intervention,destiné notamment aux forces de police ou aux troupes de maintien de l'ordre. Ce gilet comporte intérieurement une cretonne satin et extérieurement une toile, par exemple du type "Kermel" dont les qualités de résistance de chaîne et de trame assurent au gilet une bonne tenue mécanique. In the main patent, an intervention bomber vest has been described, intended in particular for the police forces or law enforcement troops. This vest has internally a satin cretonne and externally a fabric, for example of the "Kermel" type, the qualities of warp and weft strength ensuring the vest has good mechanical strength.

Entre l'enveloppe intérieure en tissu et l'enveloppe extérieure en toile, se trouve un rembourrage, notamment en mousse en matière ininflammable du type matière plastique expansée à base de chlorure de polyvinyle, par exemple de type "Klegecell".  Between the inner fabric envelope and the outer fabric envelope, there is padding, in particular of foam made of non-flammable material of the expanded plastic type based on polyvinyl chloride, for example of the "Klegecell" type.

Conformément à la présente addition, on a maintenant trouvé , d'une façon inattendue , que l'on pouvait remplacer le rembourrage de mousse en matière ininflammable par un autre rembourrage de texture entièrement différente et à résistance améliorée à la perforation. In accordance with the present addition, it has now been unexpectedly found that the foam padding made of non-flammable material could be replaced by another padding of an entirely different texture and with improved puncture resistance.

Ainsi la présente addition a-pour objet un gilet pare-coups d'intervention qui est caractérisé en ce qu'il comprend monté entre l'enveloppe intérieure en tissu de cretonne satin et l'enveloppe extérieure en toile dont l'armure est réalisée au moyen d'un taffetas et dont la chaîne et la trame sont constituées de fil5 due bonne résistance mécanique, un rembourrage en feuire aiguilleté constitué de fibre5à base de polymère d'aramide. Thus the present addition has for its object an intervention bomber jacket which is characterized in that it comprises mounted between the inner envelope in satin cretonne fabric and the outer envelope in canvas, the armor of which is made at by means of a taffeta and whose warp and weft are made of thread5 due to good mechanical resistance, padding in needled felt made of fiber5 based on aramid polymer.

Selon une caractéristique de la présente addition l'épaisseur du rembourrage est comprise dans la gamme de 6 à 8 mm et la masse en atmosphère normale dudit rembourrage se situe entre
2 4CO et 500 g/m
Le feutre aiguilleté constitué de fibresà base de polymère d'aramide~du type notamment vendu sous la désignation commerciale "Kevlar" par la Société E.I. Du Pont de Nemours
mis en oeuvre selon la présente addition peut notamment pré senter les caractéristiques suivantes:
la résistance à la traction du rembourrage est sensiblement de 22,65 kg/f dans le sens de la longueur et de 21,10 kg/f dans le sens de la largeur et la résistance à la flamme selon la norme 07113 AFNOR dans le sens de la longueur et de 12,0 et dans le sens de la largeur de 16,5.
According to a characteristic of the present addition, the thickness of the padding is in the range of 6 to 8 mm and the mass in normal atmosphere of said padding is between
2 4CO and 500 g / m
Needleloom felt made of fibers based on aramid polymer ~ of the type sold in particular under the trade name "Kevlar" by the company EI Du Pont de Nemours
implemented according to the present addition may in particular have the following characteristics:
the tensile strength of the padding is approximately 22.65 kg / f in the lengthwise direction and 21.10 kg / f in the widthwise direction and the flame resistance according to standard 07113 AFNOR in the direction 12.0 in length and 16.5 in width.

Divers avantages et caractéristiques de la présente addition ressortiront de la description détaillée ciaprès . Various advantages and characteristics of the present addition will emerge from the detailed description below.

L'addition est illustrée , à titre d'exemple non limitatif sur la figure unique du dessin annexé qui illustre une vue partielle éclatée de la texture du gilet de l'addition. The addition is illustrated, by way of nonlimiting example in the single figure of the appended drawing which illustrates a partial exploded view of the texture of the vest of the addition.

Sur le dessin annexé, on a représenté de façon schématique les trois éléments principaux constitutifs du gilet
Le symbole de référence 1 désigne un tissu cretonne satin représentant l'enveloppe intérieure du gilet. Le symbole de référence 2 désigne une toile dont l'armure est réalisée au moyen d'un taffetas et dont la chaîne et la trame sont constituées de fils de bonne résistance mécanique. Ladite toile 2 est l'enveloppe extérieure du gilet Entre lesdites enveloppes 1 et 2,on prévoit un rembourrage (3) en feutre aiguilleté constitué de fibres base de polymère d'aramide. Un tel rembourrage très approprié pour la mise en oeuvre de la présente addition est vendu dans le commerce sous la désignation de "Kevlar". I On trouvera une définition d'un polymère d'aramide dans les brevets US 3.652 510, 3.6990085 et 3.673.143.Il va sans dire qu'on peut remplacer ledit rembourrage "Kevlur" par un autre rembourrage analogue
Lors de la mise en oeuvre de la présente addition,on a effectué de nombreux essais pour éprouver le nouveau rembourrage (3) en feutre aiguilleté constitué de fibres à base de polymère d'aramide.
In the accompanying drawing, the three main components of the vest are shown schematically
The reference symbol 1 designates a satin cretonne fabric representing the inner envelope of the vest. The reference symbol 2 designates a canvas whose weave is made by means of a taffeta and whose warp and weft are made of threads of good mechanical strength. Said fabric 2 is the outer envelope of the vest Between said envelopes 1 and 2, there is provided a padding (3) of needle felt made of fibers based on aramid polymer. Such padding very suitable for the implementation of the present addition is commercially sold under the designation "Kevlar". I A definition of an aramid polymer can be found in US patents 3,652,510, 3,6990085 and 3,673,143. It goes without saying that said "Kevlur" padding can be replaced by another similar padding.
During the implementation of the present addition, numerous tests were carried out to test the new padding (3) in needle felt made of fibers based on aramid polymer.

Le tableau ci-après indique les valeurs obtenues. The table below indicates the values obtained.
