    "Security wall". The present invention relates to a security wall intended to be placed in front of at least one obstacle to partially absorb a collision shock with said obstacle, said security wall comprising a first element comprising an inlet arranged to be connected to a source of pressurized air, said first element being arranged to be inflated to a first predetermined pressure by means of air and having a collision zone, said first element being further connected to a second element arranged to be inflated to a second predetermined pressure by means of air.
    Such a security wall is known for example from document FR2930452 describing a wrapped comprising at least one inflatable element. The safety wall described in this document is intended for the delimitation of sports activity areas or games. Several envelopes comprising; at least one inflatable element can be placed next to each other in order to form a more or less long security wall, the various envelopes being fixed by means of, for example, hook-and-loop strips or a fastening system. zipper.
    Document FR2928667 discloses a deformable safety barrier comprising a flexible structure equipped with at least one housing in which an inflatable bag is inserted. This safety barrier is intended to be placed between a traffic lane and a vertical support to cushion the impact when a vehicle accidentally leaves the lane. With such a safety barrier, shock absorption depends on the predetermined and fixed pressure at which the airbags are inflated, excessive pressure is not indicated since it would harden the safety barrier and induce a "trampoline" effect. "In case of shock and too low pressure does not sufficiently dampen the shock.
    Unfortunately, such security walls are composed of elements inflated to a predetermined pressure and fixed once the security wall is in place. When a vehicle collides with such safety walls, the shock absorption therefore depends on the predetermined pressure within the inflatable elements, regardless of the magnitude of the collision force. Thus, such security walls are not suitable for the absorption of all shocks, this absorption being limited by the predetermined pressure and fixed inflatable elements.
    The object of the invention is to overcome the drawbacks of the state of the art by providing an inflatable safety wall allowing a specific shock absorption, the pressure within the inflatable elements varying according to the magnitude of the collision force exerted on said security wall .....
    Thus, to solve these problems, there is provided according to the invention, a security wall as indicated at the beginning characterized in that said first element communicates with said second element via at least one decompression valve allowing a transfer of the air contained in said first element to said second element beyond a predetermined pressure threshold in said first element, said second element further having at least one external air evacuation valve arranged for allow a transfer of the air contained in said second element to a surrounding medium, beyond a predetermined pressure threshold in said second element.
    Such a security wall allows a specific shock absorption according to the magnitude of the collision force because the pressure within said inflatable elements can vary, the air under pressure in said first inflatable element having a collision zone that can pass to said second , an inflatable element beyond a predetermined pressure threshold in said first inflatable element via at least one pressure relief valve, said second element further having at least one external air evacuation valve arranged to allow a transfer of the air contained in said second element to a surrounding medium, beyond a predetermined pressure threshold in said second element.
    Such a security wall thus allows the initial pressure of the inflatable elements to vary according to the collision force exerted against the security wall. Advantageously, this variation in pressure allows optimal absorption of the shock caused by a collision, the pressure of the inflatable elements adapting to the magnitude of the collision force. Thus, the disadvantages encountered with the inflatable safety walls described in the state of the art such as the effect "trampoline" (too high pressure of the inflatable elements) are overcome with the present invention.
    According to one embodiment of the security wall according to the invention, said security wall further comprises a third element connected to said second element, said second and third elements communicating with each other via at least one decompression valve allowing a transfer of the air contained in said third element to said second element beyond a predetermined pressure threshold in said third element. The presence of a third inflatable element enhances the effectiveness of said security wall, this third element contributing to the specific absorption of the collision force. Indeed, following a first partial absorption of said collision force by said first and second elements, said third element can still absorb a portion of the residual shock wave.
    According to another embodiment of the security wall according to the invention, said third element is divided longitudinally into a first and a second compartments.
    According to another embodiment of the security wall according to the invention ,. said first element is divided longitudinally into first and second compartments.
    According to another embodiment of the security wall according to the invention, the said second element is divided longitudinally into a first and a second compartment.
    A division of the various elements forming said security wall makes it possible to distribute the collision force through a plurality of compartments, which contributes to an optimal distribution of said collision force which is thus all the better absorbed.
    Advantageously, said first and second compartments communicate with each other via at least one decompression valve. This communication between said first and second compartments formed from an inflatable element of said safety wall ensures optimal absorption of said collision force, under pressure of said first compartment can pass to said second compartment beyond a predetermined threshold of pressure in said first compartment.
    Preferably, said security wall according to the invention comprises several air inlets each connected to a component (inflatable element or compartment formed from an inflatable element) of said safety wall. The various components of said safety wall are pressurized to an initial pressure that must be maintained permanently before a collision force is applied against said security wall; To this end, several pressurized air inlets are provided and each connected to a component of said safety wall, the pressurized air which supplies these different components being supplied by one or more compressors.
    Preferably, said security wall according to the invention comprises fixing elements for holding said security wall in place. It is in fact to maintain said security wall in front of the obstacle so that said safety wall does not move under the effect of said collision force and that it can effectively absorb said collision force.
    Preferably, said fastening elements are fastening straps and / or rings in which pass a peak.
    Advantageously, said collision zone comprises stiffening strips. Said stiffening band allow the security wall to be maintained in a suitable position ensuring optimum absorption of said collision force. These stiffening strips can also contribute to an optimal distribution of said forced collision over the whole of said collision zone of said security wall.
    Preferably, at least one of said elements of said security wall is surmounted by an advertising cover.
    Advantageously, said security wall according to the invention is formed by a succession of security walls placed side by side or superimposed.
    Other forms of the security wall according to the invention are indicated in the appended claims.
    The invention also relates to the use of a security wall for absorbing a collision shock.
    Other forms of use of a security wall according to the invention are indicated in the appended claims.
    Other features, details and advantages of the invention will become apparent from the description given below, without limitation and with reference to the accompanying drawings.
    Figure 1 is an illustration of an embodiment of the security wall according to the invention.
    Figure 2 is another illustration of an embodiment of the security wall according to the invention.
    FIG. 3 is an illustration of a security wall according to the invention in which the stiffening and fixing elements of said security wall appear.
    In the figures, identical or similar elements bear the same references.
    FIG. 1 illustrates a security wall according to an embodiment according to the invention comprising a first inflatable element (1) and a second inflatable element (2) both supplied with compressed air via inputs (3) arranged to be connected to a compressor (not shown). The first (1) and second (2) inflatable elements communicate with each other via a decompression valve (5) arranged to allow the passage of the air contained in said first element (1) to said second element ( 2) only when the air pressure in said first element (1) is greater than a threshold value. Said second element further comprises an external air evacuation valve (6) arranged to allow an air outlet of said second element (2) to a surrounding medium only when the pressure of the air in said second element (2) is greater than a threshold value. Thus, when a collision force (F) is applied against said safety wall on said collision zone (4) and when the threshold value of air pressure in said first element (1) is exceeded, said decompression (5) opens under the effect of pressure and allows a passage of air from said first element (1) to said second element (2), the external discharge valve (6) opens when the air pressure within said second element (2) exceeds a threshold value. The collision force (F) is therefore first partially absorbed in said first element (1) and then in said second element (2) where, following the application of said collision force (F), said anti-collision force is passed over said zone. collision (4), air initially contained in said first element (1). The external discharge valve (6) allows the pressure within said second element (2) not to be excessive according to a threshold value defining the opening of said external exhaust valve (6).
    FIG. 2 illustrates a safety wall according to another embodiment according to the invention comprising the same elements as those described in FIG. 1 but further comprising a third inflatable element (7) supplied with compressed air via an inlet (3) arranged to be connected to a compressor (not shown), said third element communicating with said second element (2) via a decompression valve (8) arranged to allow passage of the air contained in said third element (7) to said second member (2) only when the air pressure in said third member (7) is greater than a threshold value. Thus, when a collision force (F) is applied against said safety wall on said collision zone (4) and when the threshold value of air pressure in said first element (1) is exceeded, said decompression (5) opens under the effect of pressure and allows a passage of air from said first element (1) to said second element (2), the external discharge valve (6) opens when the air pressure within said second element (2) exceeds a threshold value. The collision force (F) is therefore first partly absorbed in said first element (1) and then in said second element (2) and finally in said third element (7). The external discharge valve (6) allows the pressure within said second element (2) not to be excessive selle a threshold value defining the opening of said external discharge valve (6).
    FIG. 3 illustrates a security wall according to the invention comprising a first inflatable element (1), a second inflatable element (2) and a third inflatable element (7). The first inflatable element (1) has, on the collision zone (4), stiffening strips (9) ensuring the maintenance of the security wall, said security wall being also fixed to the ground via fastening elements (10) themselves fixed to the ground with a stud (11).
    It is understood that the present invention is in no way limited to the embodiments described above and that many modifications can be made without departing from the scope of the appended claims.
