DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(6) Hereinafter, longitudinal will refer to a direction or plane intended to extend, during use, orthogonally to the side wall of the railway vehicle, and transverse to a direction suitable for extending, during use, parallel to the side wall of the railway vehicle and in a horizontal plane.

(7) The table 10 comprises a tray 12, at least one extendible leaf 14, at least one rotatable leaf 16, and coupling means 18, such as a hinge.

(8) The tray 12 is suitable for being secured to the vehicle. It is fastened to a window (not shown in the figures) of the vehicle. In a variant, it is fastened to a floor (not shown in the figures) of the vehicle. In another variant, it is fastened to a window and to a floor of the vehicle at the same time.

(9) The tray 12 can represent a main part of the table 10.

(10) The tray 12 includes an upper surface 22 and a lower surface 24.

(11) The tray 12 further comprises at least one guideway 25.

(12) The upper and lower surfaces 22, 24 are substantially horizontal.

(13) The guideway 25 is configured to receive the extendible leaf 14. The guideway 25 allows a translational movement in a transverse direction of the extendible leaf 14 relative to the tray 12 between a deployed position of the extendible leaf 14 and a withdrawn position of the extendible leaf 14 to the exclusion of any other movement.

(14) The guideway 25 is configured to allow a free sliding of the extendible leaf 14.

(15) Advantageously, the tray 12 also has a protrusion 26 protruding horizontally from one edge 28 of the tray 12. The protrusion 26 is opposite the rotatable leaf 16.

(16) The protrusion 26 is capable of cooperating with the rotatable leaf 16, as described hereinafter.

(17) The protrusion 26 for example has a semi-cylindrical shape. In a variant, the protrusion 26 has at least two facets.

(18) The extendible leaf 14 extends, in the elongation direction of the tray 12, between a proximal end 30 and a distal end 32. In the deployed position of the extendible leaf 14, the distal end 32 is separated from the tray 12. In the withdrawn position of the extendible leaf 14, the distal end 32 is in contact with the tray 12.

(19) The extendible leaf 14 is mounted translatably on the tray 12 between a deployed position and a withdrawn position. Advantageously, the extendible leaf 14 is mounted movably in rectilinear translation along a directly parallel to an elongation direction of the tray 12.

(20) During use, the extendible leaf 14 is arranged opposite the abdomen of a seated passenger. More specifically, the distal end 32 of the extendible leaf 14 is arranged opposite the abdomen of a seated passenger.

(21) The rotatable leaf 16 is mounted rotatably on the extendible leaf 14 between an idle position and a deployed position. Advantageously, the rotatable leaf 16 is mounted rotatably around a longitudinal axis on the distal end 32 of the extendible leaf 14.

(22) The angle between the idle position and the deployed position of the rotatable leaf 16, relative to the extendible leaf 14, is between 80 and 95, and is preferably substantially equal to 90.

(23) The rotatable leaf 16 is in direct contact with the tray 12 during its rotation from its idle position to its deployed position.

(24) The rotatable leaf 16 comprises an upper surface 34 and a lower surface 36. The upper surface 34 is flush with the upper surface 22 of the tray 12 when the rotatable leaf 16 is in its idle position.

(25) The lower surface 36 is arranged opposite a surface of the extendible leaf 14 when the rotatable leaf 16 is in its idle position.

(26) The lower surface 36 of the rotatable leaf 16 is configured to come into contact with the tray 12 during the rotation of the rotatable leaf 16 from its idle position to its deployed position.

(27) Advantageously, the lower surface 36 has a convex curved profile.

(28) The lower surface 36 of the rotatable leaf 16 has a groove 40. The protrusion 26 is able to be housed in the groove 40 when the rotatable leaf 16 is in the deployed position.

(29) During use, when the rotatable leaf 16 is in its deployed position, the rotatable leaf 16 extends substantially parallel to the lower part of the thorax at the abdomen of a seated passenger.

(30) The coupling means 18 are configured to rotate the rotatable leaf 16 from its idle position to its deployed position when the extendible leaf 14 is translated from its deployed position to its withdrawn position.

(31) Thus, an impact of a passenger on the extendible leaf 14, driving the translation of the extendible leaf 14 toward its withdrawn position, is further able to drive a rotation of the rotatable leaf 16 toward its deployed position.

(32) The coupling means 18 comprise at least one hinge 38 that articulates the rotatable leaf 16 relative to the extendible leaf 14. Advantageously, the hinge 38 is mounted at the distal end 32 of the extendible leaf 14.

(33) The hinge 38 for example incorporates an inner stop, preventing a rotation of the rotatable leaf 16 relative to the extendible leaf 14 past its deployed position.

(34) Advantageously, the hinge 38 exerts a resisting torque between the extendible leaf 14 and the rotatable leaf 16.

(35) The torque is configured so as to be able to keep the rotatable leaf 16 in several intermediate positions strictly comprised between the idle position and the deployed position, and to be able to be manipulated easily by a person wishing to pivot the rotatable leaf 16 relative to the extendible leaf 14, independently of the position of the extendible leaf 14 relative to the tray 12.

(36) In one preferred configuration, the upper surface 34 of the rotatable leaf 16 has at least one stationary bar 42. The bar 42 is configured to maintain a tablet or mobile telephone on the upper surface 34 when the rotatable leaf 14 is in an inclined position, for example at 45.

(37) In one preferred configuration, four sets of two and three extendible and rotatable leaves 14 and 16 (respectively) are mounted on a tray, which serves as a common element 12, as illustrated in FIGS. 1 and 2. Each set of second and rotatable leafs 14, 16 is across from a seated passenger.

(38) The operation of a table 10 according to the invention will now be described.

(39) By default, during the use of the table 10, the rotatable leaf 16 occupies its idle position. A passenger is at a distance from the table 10.

(40) During a sudden acceleration or deceleration, the passenger is projected toward the table 10 in the transverse direction and comes into contact with the distal end 32 of the extendible leaf 14. In this case, the passenger exerts a substantially horizontal force on the extendible leaf 14.

(41) The extendible leaf 14 is translated relative to the tray 12, toward its withdrawn position, in particular into its withdrawn position.

(42) As a result, the rotatable leaf 16 is rotated relative to the extendible leaf 14, owing to the coupling means 18, toward its deployed position, in particular into its deployed position.

(43) Preferably, the extendible leaf 14 is not translated relative to the tray 12, toward its withdrawn position, unless the force exerted by the passenger on the table exceeds the threshold. In the illustrated embodiment, the extendible leaf 14 first translates the rotatable leaf 16, until the lower surface 36 of the rotatable leaf 16 comes into contact with the protrusion 26.

(44) This contact causes a rotation of the rotatable leaf 16 relative to the extendible leaf 14 when the translation of the extendible leaf 14 toward the withdrawn position continues, until the protrusion 26 of the tray 12 becomes housed in the groove 40. The resistance exerted by the tray 12 on the rotatable leaf 16 interrupts the movement of the extendible leaf 14 and the rotatable leaf 16.

(45) After such an incident, the table 10 can be returned to its initial configuration by exerting a horizontal force on the extendible leaf 14 toward the deployed position of the extendible leaf 14, and exerting a torque on the rotatable leaf 16 toward the idle position of the rotatable leaf 16.

(46) Owing to the invention described above, passenger safety is better ensured, in particular during accidents. The passenger impact surface is increased, which decreases the pressure exerted by the tables on the passengers in case of impacts, and decreases the risks of passenger injury.

(47) The table according to the invention further makes it possible to hold books or small electronic apparatuses with a selected incline of the rotatable leaf 16, and thus facilitates the activities of the passengers more ergonomically.

(48) When the rotatable leaf 16 is in its deployed position, additional spaces are thus created to facilitate access to seated places for passengers with reduced mobility.
