• the warp threads 1 can have a mass in grams of between 200 to 1,500 decitex.
• the reinforcing mesh also comprises pairs of so-called "reinforcing" wires which are shown here by way of example in the number of four pairs bearing the references 2 j to 2 4 .
• Each pair 2 comprises two wires 3 and 4 which have the characteristic of being interlaced to form successive alternating loops in a weft direction which is generally considered to be perpendicular to the alignment of the warp wires 1.

• Each wire rope can have a structure between that usually defined by the expressions 3 ⁇ 1 to, for example, 7 ⁇ 7. It is advantageous within the meaning of the invention that the wire cables chosen have a diameter of between 0.3 and 1 mm.
• the cable chosen can have a diameter of 0.65 mm, while for a 3 x 7 type structure such a diameter can be around 0.63 mm.
• the reinforcement mesh from a "hook" type machine which offers the advantageous characteristic of allowing lacing to be made of strips of more or less large width capable of be packaged in the form of rolls or, by analogy, of coils or of plates in precut format.
• the structure of the lacis as described above makes it possible to confer, by tying and conformation in alternating loops, an overall cohesion to the different threads which are established in the form of a wide mesh ply easily deformable in all directions because of the relative freedom which the connection points allow to remain 10.
• This characteristic is of immense advantage because it offers an undeniable possibility of own conformation, allowing the reinforcing mesh to adopt and marry all the geometric shapes of the products, articles or objects with which it must be associated.
• the reinforcing mesh according to the invention has a specific weight or a grammage which can be between 300 g to 2 kg per m 2 .
• the reinforcing mesh has the characteristic of being produced in the form of a regularly meshed network including closed loops 5 relatively close to each other. others both in succession parallel to the warp threads 1 and transversely in the weft direction from one pair of reinforcing threads to another.
• this regularly meshed network offers perfectly homogeneous resistance to blunt or cutting stresses which can be applied to it according to a normal or intersecting trajectory in rectilinear or curvilinear directions.
• a reinforcing mesh presents, by the succession and the presence of the metallic cables 3, 4, a great resistance to incisive and cutting actions from a sharp and resistant blade.
• a lacing nevertheless offers a suitable aptitude for cutting by shearing action, which makes it possible to give it any geometric shape necessary, useful or compatible with the conformation of the product, object or article to which it must be associated to ensure its reinforcement.
• the mesh comprises a plurality of warp threads 1 extending parallel to each other.
• These wires 1 can be established in a ply or, on the contrary, in two plies between which the pairs of reinforcing wires are arranged.

• the lacis has a relative mechanical "hold” in its plane and can be more easily handled or conditioned.
• Lacis constitutes, in this form, a coating complex.
• the lacis can still be completed, as illustrated in fig. 3, by the addition, on one of its faces, of a layer 15 of flexible material having at least on the surface an adhesive character.
• Lacis L is then associated with such a layer with which it constitutes a coating complex, one of the faces of which corresponds to the structure of the lacis, while the other, which may be flat, smooth or, on the contrary, dimpled. adhesive on contact.
• the material which can be used to constitute such a layer does not properly fall within the scope of the invention, since it must be considered to be commercially available to a person skilled in the art. It may be a polymer-based composition, such as silicone, neoprene or hot melt with a permanent adhesive nature. As illustrated by the presence of the dashed line in FIG.
• Fig. 4 shows an alternative embodiment in which the lacis L is coated with a matrix 17 which meets the preceding characteristics of the layer 15.
• the matrix 17 can then be associated with two peelable protectors 18 and 19.

• the passage between the conveyor 21 and the cylinder 22 ensures the intimate connection between the lacis L and the layer 15 into which it is caused to penetrate through the surface opposite the protector 16.
• Fig. 6 shows a further development in which the lacis (L) constitutes a structure or a reinforcing core of a covering complex designated as a whole by the reference 30.
• a complex comprises, for example, a fabric 31, of the velvet type or the like, on the rear face of which lacis L is attached by gluing in its original form or even in one of those illustrated in FIGS. 3 or 4, as shown respectively in the right and left part of FIG. 6.
• Such a complex advantageously constitutes a finished product allowing the covering of all or part of the surface of a structure, of a product, of an object or of an article whose resistance must be improved at the same time as the appearance aesthetic comfort.
• the application to the surface of the product, of the article or of the object may take place directly by taking advantage of the adhesive or adherent face of the lacis, of the layer 15 or of the matrix 17 or else by applying beforehand as an interface layer an adhesive product or else a product with controlled polymerization over time.
• Such a complex 30 meets the characteristics set out above of flexibility, draping, possible conformity and custom cutting by shearing to present in plan the developed form of the object produced or article to be covered. Given the presence of the lacis L on the internal face, any cutting or blunt action applied to the covering or fabric 31, will have no other consequence than the presence of a barely visible notch, without risk of complete deterioration of the complex likely to reveal by a gaping opening thus produced, the nature of the protected product, object or article.
• FIG. 7 shows such an application in relation to a seat cushion 40 which is only shown in relation to a seat structure not directly concerned with the subject of the invention.
• a seat 40 for example formed wholly or partly by a foam filling 41, it suffices to cut the covering complex 30 in a shape such as that illustrated in the drawing. Such a cut can be carried out by retaining for a given direction a total dimension D corresponding to the elementary measurements, d j equal to the width 1 of the seat, twice d 2 equal to the thickness e of the seat and two times d 3 equal to returns e.
• the reinforcing mesh according to the invention certainly responds positively to the provision of improved resistance against actions of a cutting or blunt nature.
• the lacis according to the invention also makes it possible to offer good resistance to the so-called "corkscrew" test.
• the corkscrew has no other effect than taking over a wire 3 or 4 which is pulled during the pulling action, without being subject to breakage , since its conformation in successive half loops and its absence of rigid connection allow it to unwind without being subjected to a break.
• Fig. 9 shows an alternative embodiment in which at least one of the sides of the lacis L is produced as said with reference to FIGS. 1 and 2 but from yarns 3a and 4a based on synthetic material, the composition of which may be identical or analogous to that of warp yarns 1.
• the yarns 3a and 4a thus form an edge or an edge 50 having an even more character flexible to promote extreme draping, turning and stapling, especially in the application to the upholstery of a seat.
• the width of lacis L including for example two selvedges 50, can advantageously correspond to dimension D.
• the object of the invention is particularly suitable for the anti-vandalism reinforcement of seats of public transport vehicles.
