DETAILED DESCRIPTION

(10) Elements that are present in more than one of the figures are given the same references in each of them.

(11) FIG. 1 shows an arrangement 1 according to the disclosure. This arrangement 1 may be installed in various systems and, for example, in a building or a vehicle.

(12) The arrangement 1 comprises a structure 2 delimiting an emergency exit 10. This structure 2 comprises, in particular, a partition 3 at least partially delimiting the emergency exit 10. The partition 3 may be situated above the emergency exit 10 when the arrangement 1 and, where applicable, the vehicle, is on the ground 100.

(13) By way of illustration, the emergency exit 10 may be arranged laterally between two frames 4, 5 in a first direction, and in a second direction between the partition 3 and a separation 6. Optionally, the arrangement 1 may include coverings 7 around the emergency exit 10. Optionally, the structure 2 may include a support, such as a plate secured to the partition 3.

(14) Furthermore, the arrangement 1 comprises a movable panel 15. This panel 15 comprises a border 16 attached to the structure 2 by conventional reversible attachment devices 85. Such devices 85 comprise, by way of example, pins that each penetrate a hole in the border 16 of the panel 15 and a hole in the structure 2, each pin being secured to a cable capable of pulling the respective pin out of at least one of said holes.

(15) In the inactive operating mode MODINAC shown in FIG. 1, the panel 15 closes the emergency exit 10. The panel 15 therefore prevents an individual from passing through the emergency exit 10. In an emergency operating mode, the panel 15 is moved, or indeed completely removed from the structure 2. The emergency exit 10 is no longer closed, and an individual can pass through this emergency exit 10.

(16) The border 16 may be part of a wall 18 or may be secured to a wall 18. Optionally, the wall 18 is at least partially transparent or translucent in the context of a porthole or a window.

(17) Furthermore, the border 16 and the partition 3 together delimit a recess 19.

(18) For example, the border 16 comprises two sides 161, 162 connected by a bottom 17. The sides 161, 162 may be substantially parallel to one another and substantially orthogonal to the bottom 17. The border 16 is then U-shaped with respect to the partition 3. The bottom 17 may be substantially parallel to the partition 3. The recess 19 may have a substantially parallelepiped external shape. The reverse is also possible, the partition having a U-shaped profile facing one face of the panel. According to another example, the partition and the border may each have complementary L-shaped profiles.

(19) Irrespective of these aspects, the arrangement 1 comprises an evacuation system 20 provided with a lifeline 30. The lifeline 30 comprises an elongate element 31 that extends from a proximal end region 32 to a distal end 33. For example, this elongate element 31 comprises a strip, a strap or a rope and/or is made from polyester.

(20) For example, the lifeline 30 comprises a section 41 to be deployed provided with the proximal end region 32. The section 41 to be deployed is housed in a housing 50 secured to the structure 2, for example secured to the partition 3 or to a support close to the partition 3.

(21) Furthermore, the lifeline 30 comprises a deployment section 42, possibly provided with the distal end 33 that, if applicable, extends the section 41 to be deployed. The lifeline 30 then passes, if applicable, through an opening in the housing 50, the section 41 to be deployed being in the housing 50 while the deployment section 42 is outside the housing 50 in the inactive operating mode MODINAC.

(22) Optionally, the section 41 to be deployed may be retained by a member in order to be attached to the structure 2 at all times. For example, the section 41 to be deployed is retained directly by the structure 2 or indirectly via the housing 50. According to one possibility, the proximal end region 32 may form, for example by stitching, bonding or the like, a loop 320 traversed by a rod 430 of the housing. The section 41 to be deployed is then able to rotate about this rod 430 in order to be unwound.

(23) Furthermore, the deployment section 42 passes through a passage 300 in the partition 3 into the recess 19 in the inactive operating mode MODINAC. In the recess 19, the deployment section 42 is secured to a handle 60 that is effectively inaccessible in the inactive operating mode MODINAC. The partition 3 is therefore positioned between the housing 50 and the emergency exit 10.

(24) FIGS. 2 and 3 show an evacuation system 20 in an exploded view and in a three-dimensional view respectively.

(25) With reference to FIG. 2, the housing 50 may, for example, comprise two plates 51, 52 arranged on either side of a discontinuous wall 53. The plates 51, 52 and the discontinuous wall 53 may be traversed by conventional attachment means 54, such as screws, rivets or the like. The wall 53 is discontinuous because it has an opening that brings an internal space INT of the housing 50 into communication with an external environment EXT.

(26) Optionally, the section 41 to be deployed is wound around itself in the housing 50 in the inactive operating mode MODINAC. Optionally, the proximal end region 32 is attached to the housing 50 by conventional means. As indicated above, the proximal end region 32 can form a loop 320 around an attachment means 54 and, for example, around a hollow rod 430 through which a screw or a rivet passes.

(27) Irrespective of these features, the deployment section 42 successively comprises an initial section 43 that is secured to the section 41 to be deployed and a connecting section 44 secured to a handle 60.

(28) A conventional handle can thus be attached to the deployment section 42.

(29) Alternatively, and according to the figures, and in particular FIG. 3, a final section of the lifeline extends the deployment section 42 and forms the handle 60. This final section then comprises, successively, a start section 45 secured to the connecting section 44, an intermediate section 46 and an end section 47 comprising the distal end 33. The final section may be partially folded back on itself in order to form the handle 60. For example, the final section is folded substantially 180 degrees after the start section 45, then substantially 180 degrees after the intermediate section 46, so that the end section 47 is attached to the start section 45, for example by stitching, welding and/or bonding.

(30) According to another feature, the arrangement 1 may comprise a sheath 61 surrounding said intermediate section 46.

(31) According to another feature, the arrangement 1 may include a ballast 62 secured to the deployment section 42, or indeed to the handle 60. For example, the ballast 62 is attached to the intermediate section 46 or to the sheath in a conventional manner, for example by bonding, stitching or the like. If required, the ballast 62 may be arranged in the sheath 61.

(32) According to another optional feature shown in FIGS. 1, 2 and 3, the deployment section 42 may be provided with a holding system in order to prevent it from rubbing against external elements during the inactive operating mode MODINAC.

(33) For example, the initial section 43 may be secured to a self-gripping retaining fastener 71. For example, the retaining fastener 71 is attached to the initial section 43 by stitching, bonding or the like. This retaining fastener 71 can cooperate with a support fastener 72 of the housing. In the inactive operating mode MODINAC, the retaining fastener 71 is engaged with the support fastener 72.

(34) According to the example shown in FIG. 3, a self-gripping support fastener 72, complementary to the retaining fastener 71, is secured to said housing 50. In the inactive operating mode MODINAC, the retaining fastener 71 is engaged with the support fastener 72. Optionally, the initial section 43 is slack between the housing 50 and the retaining fastener 71.

(35) According to another aspect, the assembly may include a system for preventing the lifeline from unwinding in an unwanted manner.

(36) With reference to FIG. 4, the assembly may therefore comprise a reversible anti-unwinding system for keeping the section 41 to be deployed in the housing during the inactive operating mode MODINAC.

(37) For example, the anti-unwinding system is provided with two self-gripping immobilizing fasteners 710, 720 each secured to the section 41 to be deployed. The two immobilizing fasteners 710, 720 are engaged with each other in the inactive operating mode MODINAC.

(38) Additionally, or alternatively, the deployment section 42, or indeed the handle 60, may comprise a self-gripping attachment 73 configured to be engaged with the structure 2. For example, the self-gripping attachment 73 is arranged on the start section 45, if applicable, being attached thereto by stitching, bonding or the like.

(39) With reference to FIG. 4, a self-gripping resting fastener 74, complementary to the attachment 73, may be attached to the partition 3, facing the emergency exit 10.

(40) A double fastening system can thus attach the lifeline respectively above the partition 3 and at the handle 60 in the recess 19.

(41) According to another feature and in reference to FIG. 5, the section 41 to be deployed may carry a plurality of grips 80 attached to the lifeline by stitching, bonding or the like. These grips 80 may comprise pieces 81 referred to as “patches” and/or loops 82, for example. The grips 80 may be arranged alternately on either side of a strip 31 of the lifeline 30.

(42) FIG. 6 shows an assembly 1 according to the disclosure in the inactive operating mode MODINAC. At least one space may separate the handle 60 and the deployment section from the walls 161, 162, 17 of the panel 15 and indeed from the partition delimiting the recess 19. For example, two lateral spaces J1 and J3 separate, along a first axis AX1, the handle 60 and, respectively, the first side 161 and the second side 162, and a vertical space J2 separates the handle 60 and the bottom 17, along a second axis AX2 orthogonal to the first axis AX1.

(43) During the emergency operating mode MODSEC shown in FIG. 7, an individual maneuvers the panel 15. This panel 15 is removed with a rotational and/or translational movement MOV. The various spaces, if provided, make it possible to prevent contact between the panel 15 and the handle 60. The individual can take hold of the handle 60 in order to deploy the lifeline 30. The lifeline 30 can also be retained via its proximal end region by the structure 2 or indeed the housing 50.

(44) According to FIG. 8, such an arrangement 1 may be arranged on a vehicle 95, for example an aircraft. For example, two arrangements 1 are arranged on either side of a cabin 96 in order to ensure an arrangement 1 is available even when the vehicle is lying on one side. In particular, one arrangement 1 is situated on a first side 97 of the vehicle and another arrangement 1 is situated on a second side 98 of the vehicle 95.

(45) Each lifeline 30 may be dimensioned to reach the ground 100 according to both the position shown by a continuous line and the position shown by a dashed line. Alternatively, a lifeline 30 may be dimensioned to approach the ground without touching it and allow a human to safely reach the ground.

(46) Furthermore, it should be noted that, if required, the lifeline 30 may carry grips 80 only in useful areas.

(47) Naturally, the present disclosure is subject to numerous variations as regards its implementation. Although several embodiments are described above, it should readily be understood that it is not conceivable to identify exhaustively all the possible embodiments. It is naturally possible to envisage replacing any of the means described by equivalent means without going beyond the ambit of the present disclosure.
