Definitions

  • the present invention relates to a rotary seat with improved movement, especially for rail vehicles.
  • a seat of the type comprising a mobile upper part for receiving at least one occupant carried by a part fixed lower forming base and turning means of the upper part back and forth and vice versa.
  • Seats of this type are arranged in particular in vehicles rail.
  • the means for reversing a seat make it possible to reverse the orientation front-rear of this seat so as to place this seat and the passenger (s) occupying it (s) in the direction of movement of the vehicle, regardless of the direction in which this vehicle travels a path.
  • the seats of a railway vehicle are arranged close a left or right side wall of this vehicle.
  • the space between the seats and the neighboring side wall is preferably the most reduced possible, the movement of a seat from front to back (and conversely) by simply rotating the movable upper part of the seat around a fixed vertical axis is hindered by the side wall. Because of this, generally the reversal a seat is made, first of all, by moving the movable upper part of the wall next to the seat, then by rotating this movable part around a vertical axis and finally by bringing this movable part closer to the wall next to the seat.
  • a seat according to the preamble of claim 1 is known from US-1,902,282.
  • the object of the invention is to provide a seat, in particular for a vehicle rail, equipped with space-saving turning means, light and simple to maneuver in order to quickly reverse the front-rear orientation of all the seats of a railway vehicle.
  • the invention relates to a seat according to claim 1.
  • the invention also relates to a rail vehicle comprising a seat as defined above.
  • FIG. 1 shows a seat 10, according to the invention, arranged in a rail vehicle 12.
  • the seat 10 comprises a movable upper part 14 carried by a part fixed lower 16 secured to a floor 18 of the vehicle 12.
  • the upper part 14 is intended to receive at least one occupant, for example two occupants as in the case shown in Figure 1.
  • the upper part 14 includes seat cushions 20 and backrest 22 as well as armrests 24.
  • the upper part 24 is arranged at proximity of a side wall 26 of the vehicle 12.
  • the seat 10 also includes means 28 for turning over the part upper 14 from front to back and vice versa. These turning means 28, illustrated in more detail in Figures 2 to 9, allow to place the seat 10 in one or the other of its two normal use positions shown in Figures 5 and 9.
  • the turning means 28 comprise a carriage 30 connecting the part upper 14 and the base 16 of the seat.
  • This carriage 30, integral with the upper part 14, is mounted movable in rotation about a substantially vertical axis Z, linked to this carriage, and in translation substantially perpendicular to this Z axis in a rectilinear light forming a guide 32 formed in a substantially horizontal wall 34 delimiting the base 16 (see especially Figures 2 to 4).
  • the wall 34 separates two parts of the carriage 30, respectively inner and external to the base 16, these two parts being interconnected by a part intermediate 36 forming pivot of axis Z.
  • Guide 32 extends substantially parallel to a transverse vertical plane of the vehicle, such as the plan in Figure 1.
  • the external part of the carriage 30 forms a head 38 for supporting this carriage on the wall 34 of the base.
  • the head 38 is in sliding contact with the wall 34.
  • the carriage 30 is resiliently returned to the rest position, against a first end 32A of the guide (on the left considering FIG. 4) by a spring traction 40 hung on the base 16 and the interior part of the carriage 30.
  • the first end 32A of the guide is closest to the side wall 26 of the vehicle, next to the seat, the second end 36B of the guide (on the right considering FIG. 2) therefore being the furthest from this side wall 26.
  • the inner part of this carriage is rotatably mounted around the Z axis on a sliding cross member 42 on a pair of rails 44 substantially parallel to the guide 32.
  • the rails 44, integral with the base 16, are arranged for example inside this base 16, on walls substantially vertical delimiting the base 16 (see in particular Figures 2 and 3).
  • the base 16 and the carriage 30 have complementary shapes for immobilizing this carriage in rotation when it is in its rest position such that shown in particular in Figures 2 and 4.
  • these shapes complementary are provided, one 46, on the contour of the head 38 of the carriage, and the other 48, on a base 50 arranged on the wall 34.
  • the complementary immobilization surfaces 46.48 can advantageously be delimited by bevelled edges favoring the vertical immobilization of the carriage 30.
  • the immobilization form 46 formed on the head 38 of the carriage has as axis of symmetry the axis Z.
  • the turning means 28 also include means 52 drive in translation of the carriage 30 along the guide 32, shown in particular in FIG. 2, and means 54 with gear for transforming this movement of translational movement in rotation about the Z axis of the carriage 30, shown especially in Figures 5 and following.
  • the drive means 52 comprise a cable traction device 56 having a first end connected to the inner part of the carriage 30 and a second end connected to a control lever 58.
  • This control lever 58 has a first support end 58A articulated inside the base 16 around a geometric axis substantially orthogonal to the Z axis, and a second operating end 58B extending outside of the base 16 through an opening 60 of the latter.
  • the cable extends between the carriage 30 and the control lever 58 on a return pulley 62.
  • the gear means 54 comprise a toothed pinion 64, integral in rotation of the carriage 30, intended to cooperate with first and second racks 66,68 carried by an articulated assembly 70.
  • the pinion 64 carried by the inner part of the carriage 30, has a coincident axis with the Z axis.
  • the assembly 70 is articulated around three axes Z1 to Z3 substantially parallel to the Z axis.
  • the assembly 70 comprises a frame forming a support 72, carrying the racks 66.68, and a member for selecting one or other of the racks provided with a first tip forming rocker 74 and a second end forming rod 76 deformable elastically.
  • the frame 72 is articulated on the base 16 around the first axis Z1 joint.
  • the rocker 74 is also articulated on the base 16 around the second axis of articulation Z2.
  • the rod 76 constituted for example by a spring of compression, has one end of connection with the flip-flop 74 and one end articulated on the frame 72 around the third axis of articulation Z3.
  • the third axis of articulation Z3, connecting the frame 72 and the member of selection, extends substantially between the two other axes of articulation Z1, Z2.
  • the racks 66,68 have facing teeth and are arranged roughly symmetrically with respect to a plane containing the Z axis, on either side of the pinion 64.
  • the pinion 64 is intended to mesh with the first rack 66 when it moves in translation from the first end 32A to the second end 32B of the guide and with the second rack 68 when it moves in the opposite direction, from the second end 32B towards the first end 32A of the guide.
  • Each rack 66,68 is selected in the engagement position with the pinion 64 by causing the third articulation axis Z3 to cross a position in which it is coplanar with the other two axes of articulation Z1, Z2. Crossing this position is obtained by actuating the selection member, more particularly the rocker 74 of this member, with a selection finger 78 carried by the carriage 30.
  • the rocker 74 allows therefore to place the frame 72 in two stable positions which are substantially symmetrical by relative to the plane containing the first and second axes of articulation Z1, Z2.
  • the finger selection 78 is pivotally mounted around the Z axis on the inner part of the carriage 30.
  • the selection finger 78 is resiliently returned to a rest position, as shown in Figure 5, by a pair of counter tension springs 80 connecting this selection finger 78 to the sliding cross member 42.
  • the finger selection plane 78 In the rest position, the finger selection plane 78 has for plane of symmetry the plane containing the first and second axes Z1, Z2.
  • the selection finger 78 is therefore movable on either side of this plane of symmetry against the elastic restoring force of one or other of the springs antagonists 80.
  • the upper part 14 of the seat is in a first position normal use of this seat as shown in Figure 5.
  • the carriage is biased by the spring 40 against the first end 32A of the guide. Shapes complementary 46,48 immobilization in rotation of the carriage cooperate with each other.
  • the control lever 58 is in its high position (see FIG. 2). Pinion 64 is the distance from the racks 66,68.
  • Lowering the control lever 58 has the effect of moving the carriage 30 in translation, substantially parallel to a transverse vertical plane of the vehicle 12, the first end 32A towards the second end 32B of the guide.
  • the pinion 64 meshes with the first rack 66 which has the effect of turning the carriage 30 and the upper part 14 around the axis Z, clockwise when considering the figure 6.
  • the finger selection 78 cooperates with a ramp of the scale 74 in order to rotate the latter around the axis Z2, as shown in Figures 7 and 8.
  • the pivoting of the flip-flop 74 which goes against the elastic return force of the selection finger 78 (antagonistic springs 80), allows the third articulation axis Z3 to cross its position in which it is coplanar with the other two axes of articulation Z1, Z2 and thus making the pinion 64 mesh with the second rack 68.
  • the pinion 64 meshing with the second rack 68, rotates around the Z axis the carriage 30 and the upper part 14 of the seat, always in the same clockwise considering Figures 5 to 9.
  • the pinion 64 cooperates with the second rack 68 until completion of the inversion of the upper part 14 of the seat.
  • the carriage 30, always recalled elastically by the spring 40, completes its displacement by a translation along the guide 32 to the first end 32A of this guide so as to bring the part upper 14 of the seat of the side wall 26, to reach the second normal position of use of the seat shown in FIG. 9.
  • the head 38 having the axis of symmetry the axis Z, cooperates again with the base 50 to immobilize the carriage 30 in rotation.
  • the operator moves the upper part 14 according to a path necessarily opposite to that described previously.
  • electrical means for example motorization means intended for drive the upper part 14
  • the electric cables extending if necessary between this part 14 and this base 16 are not liable to accidentally wrap around the carriage 30 following successive rotations of the upper part 14 still in the Same direction.
