However, in the embodiment shown in FIG. the protection device comprises two arches 2, 3 disposed on either side of the median longitudinal vertical plane of the vehicle so that a bow 2, 3 is present at the rear of each seat 34, 35, transversely to the vehicle.
- Each arch 2, 3 is composed of two bars 4, 5 articulated to one another by one of their ends.
- the hoops are movable between a retracted position in which the bars 4, 5 form an obtuse angle and a protective position in which the bars 4, 5 form an acute angle.
- the bars form an angle close to 180 ° when the arches are in their retracted position.
- the bars can be curved.
- the angle is measured between the straight line connecting the first end 6 of the hoop to the articulation of the two bars 4, 5 and the straight line connecting the hinge of the two bars 4, 5 to the second end 7.
- the first end 6 of the arch comprises a pivot attachment means 10 on the vehicle.
- the protective device 1 also comprises a guide element 8 in translation of the second end 7.
- the protection device 1 is secured to a structural element of the vehicle 9.
- the structural element 9 is composed of a substantially horizontal cross member 1 1 and / or feet 12.
- the protection device 1 may be placed partly or completely inside the cross member 11 as illustrated in FIG.
- the space below the cross member is free and can serve as a luggage storage space and / or roof elements when it is a retractable roof vehicle.
- the protection device 1 is well suited for a modular assembly.
- the protective device 1 can be pre-assembled on a beam 13, shown in FIGS. 8 and 9, before being mounted on the structural element 9 of the vehicle.
- the module may consist of a device 1 composed of a hoop or two arches 2, 3.
- the modular assembly makes it possible to test the correct operation of the device 1 outside the vehicle, for example on a test bench, and to simplify the final assembly on the vehicle.
- the first end 6 of the hoop 2, 3 is pivotally mounted on an axis located near the lateral side of the vehicle.
- the device is very insensitive in the event of a lateral impact preceding the overturning of the vehicle. Indeed during a side impact, the hoops 2, 3 through their different joints allow some deformation of the body without affecting the reliability of deployment.
- the guide element 8 is thus disposed towards the inside of the vehicle, it will not be deformed in case of side impact.
- the first end 6 of the arch 2, 3 is pivotally mounted on the structural element by means of a bearing 14.
- the bearing 14 is composed of a fixed part and a shaft secured to the first end 6 of said arch 2, 3 and articulated in rotation on the fixed part.
- a torsion spring 15 forms a prestressing means for the deployment of the hoop 2,3.
- the spring 15 is prestressed when the arch 2, 3 is in its retracted position.
- the torsion spring 15 has a first end connected to the movable part of the bearing and a second end connected to the shaft. Note that the torsion spring 15 may be disposed around or inside the shaft.
- the prestressing means for the deployment of the hoops is constituted by at least one elastic means.
- the prestressing means may be a compression spring or a tension spring.
- the spring may for example be disposed inside the crossbar 13.
- the second end 7 has a crank pin 16 which is movable in a guide element 8 such as a slide.
- the guide element 8 extends on either side of the arches 2,3.
- the guide member 8 has a non-return system to prevent the movement of the arch 2, 3 to its retracted position.
- the anti-return system is composed of at least one ratchet or a ratchet.
- the slide 8 comprises two pawls 17, 18 rotatable about pins 19, 20 disposed near the side edges of the slide 8.
- the pawls 17, 18 are equipped with teeth and a spring makes it possible to return the pawls 17, 18 to a position in which the pawls 17, 18 are parallel to the direction of the slide 8.
- crank pin 16 During the movement of the arch 3, 4 towards its protective position, the crank pin 16 causes the pawls 17, 18 to rotate about their axis 19, thus allowing the pin 16 to move.
- the crankpin 16 cooperates with a surface 21 of the teeth which is perpendicular to the direction of movement of the crankpin 16. Thus, the movement of the crankpin 16 is blocked preventing the hoop 2, 3 from returning to its retracted position .
- the slide 8 has on these lateral edges two fixed pawls 22, 23.
- the fixed pawls 22, 23 have teeth arranged to allow the passage of the crank pin 16 during the movement of the arch 2, 3 to its protective position and prevent the return of the arch 2, 3 to its retracted position.
- the pawls 22, 23 are movable and pivot about an axis parallel to the crankpin 1 6.
- anti-return devices could consist of "Rochet” systems (toothed gears and ratchets) arranged near the bearings.
- the system for triggering the movement of the hoops comprises a prestressing means for deploying the hoop 2, 3, a trigger 24 activated in the event of the vehicle overturning and a locking member 25 which maintains the prestressing and released by the trigger 24 thus releasing the arch 2, 3 of its retracted position.
- the second ends 7 of the arches 2, 3 have a tab 26a
- the locking member 25 is in the form of a stirrup composed of two rods 27, 28 linked by a connecting element 29.
- the first rod 27 is engaged in housings 36, 37 of brackets fixed to the cross member 11 and in the housings of the tabs 26a, 26b of the hoops 2,3.
- the second rod 28 is in contact with a trigger 24 such as an explosive cylinder. The trigger causes movement of the stirrup to disengage the first rod 27 of the housing legs 26a, 26b.
- the arch 2, 3 is released and the prestressing means cause its deployment.
- the locking member 25 is composed of a locking member 30 having two hooks 31, 32 arranged to receive the crank pins 16. Thus, the movement of the crank pins 16 is locked.
- a trigger rod 24 pushes the locking piece 30 to release the crank pins 16.
- a locking member 25, located between the hoops 2,3, locks two arches 2, 3, a trigger 24 for disabling the locking member 25.
- each arch 2, 3 can be locked by an independent locking member 25.
- the locking member may also be disposed near the bearing 14. According to the embodiment illustrated in FIG. 6, in order to increase the resistance of the arches 2, 3 to the forces in the direction x, the longitudinal direction of the vehicle, the shape of the bars 4, 5 is ellipsoidal or elliptical.
- the bars 4,5 receive a seal to hide the hoop 2, 3 when in the retracted position.
- the bars may also have a particular shape, as shown on the right side of Figure 6, to cover the cross 1 1.
- the arch 2, 3 has a larger section at its first end 6, illustrated in FIG. 7, and / or at its second end 7.
