By forgetfulness or laziness, he these manual operations may not be performed, so that the seat structure can move with its occupant when braking violent or in the event of a rear impact, with the risk of injuring this occupant.
  • the object of the present invention is to remedy these drawbacks by providing equipment that does not require any additional operations to connect the seat structure, first with the arm of the transfer structure and then with the cradle arranged in the vehicle.
  • the structure of seat comprises, in its part cooperating with the positioning means and the pallet connecting means, a locking mechanism on the pallet actuated automatically by the extraction of one of the wheels of the seat, while the cradle is provided with a) at the front, at least one hook pivoting in the vertical plane and able to cooperate with a ring projecting towards the low from the seat structure, this hook being wedged on a transverse shaft horizontal, connected on the one hand to the rod of an electric control cylinder and, on the other hand, at the front end of a longitudinal connecting rod, b) to the rear, of a transverse shaft linked in rotation to the other end of the connecting rod connection and carrying at least one hook pivoting in the vertical plane and suitable for cooperate with a ring projecting downwards from the seat structure, and c) of a contactor arranged in the vertical path of installation of the seat structure on the cradle and arranged on the supply circuit of the electric actuator.
  • the seat structure is perfectly secured to its cradle, therefore to the vehicle, which improves the safety of the disabled person sitting in this seat.
  • the positioning between pallet and seat structure is ensured by engagement of a vertical finger, protruding upwards from the pallet, into a hole in the bottom of the seat structure, and the locked connection of this seat structure to the pallet is provided by a flat lock cooperating with a groove in the finger of the pallet, this lock being slidably mounted relative to the bottom of the structure, subjected to the action of spring means tending to engage it in the finger and held in the retracted position by a set of levers subjected to the thrust of a pin ensuring positioning in the seat structure of one of the rolling means of this seat.
  • the only disassembly of the front rolling means releases the levers and allows the lock spring, which has become preponderant, to engage the lock in the throat of the vertical finger, blocking the connection of the structure seat with transfer structure.
  • this equipment is composed of a transfer structure A able to cooperate with the structure of seat B to bring it on a cradle C arranged on the floor 2 of a vehicle 3 or on the contrary to move the seat structure of the vehicle to outside.
  • the seat structure B comprises a quadrangular chassis 4 carrying a rear transverse axle 5 on the ends of which are mounted, removably, but with the possibility of rotation, two large wheels 6.
  • the chassis 4 also carries two transverse bearings 7 in each of which is engaged a stud 8, integral front rolling means and, in particular, a swan neck 9 bearing, by a fork 10, a caster 12.
  • the tenon 8 has a cross section not circular for stalling in rotation these rolling means relative to the bearing 7 which has a spring lock 13 cooperating with the lug 8 to wedge it in translation.
  • the transfer structure A comprises a vertical column 14 mounted freely in rotation between a plate 15 (shown in Figure 1) arranged in the floor, and a bearing 16 fixed against the door pillar 17 of the vehicle.
  • This rotary column is integral two bent levers 18 disposed substantially radially and bearing, each at their end, a bearing 19 for a vertical articulation.
  • On this last, are mounted free in rotation of the legs 20, projecting substantially radially of an upright 22 forming part of an articulated quadrilateral and deformable.
  • This amount is linked to another amount 23, smaller than it, by two levers 24a, 24b, articulated around horizontal axes 25, arranged respectively on the large upright 22 and on the small upright 23.
  • the small upright 23 carries, at the end of two substantially radial lugs 26, bearings 27 used for guiding in rotation a vertical axis 28, integral with a horizontal and pivoting arm 29.
  • a pallet 30 is mounted in translation longitudinal on this arm. This palette presents, in cross section, a trapezoidal shape with the short side facing up.
  • the horizontal wall 30a of the pallet 30 comprises, projecting from its rear edge and upwards, a stop ring 32 and projecting from its central part, a vertical finger 33 with throat 33a.
  • the transfer structure can rotate around three vertical axes, namely that of column 14, that of joints 19 and that of axis 28, which facilitates its movements inside of the passenger compartment of the vehicle, when traveling through the passage of the front door 11 (in FIG. 1), and during the gripping and removing the chair.
  • These last maneuvers are carried out with the help of a electric actuator 34 whose body is linked by a horizontal articulation 35 to a bent extension 22a of the large upright 22 and the rod of which is linked, by a articulation 36, at the small upright 23.
  • the power supply to the jack 34 is controlled by a manual box, not shown, and allowing control the up and down movement of the cylinder rod by relative to its body, and consequently of the arm 29 with the pallet 30.
  • the chassis 4 of the seat structure B is secured to a bottom 40 which, as shown in FIG. 4, presents in section transverse, a central part of trapezoidal shape complementary to that of the pallet 30 with two lateral protective wings 40a giving it a Omega shape.
  • the horizontal wall 40b of this bottom comprises substantially in the middle, a hole 42, visible in FIG. 3, and for example a hole formed in a bearing not shown. This hole is intended to cooperate with the vertical finger 33 of the pallet 30. Above this hole, is disposed a housing 43 containing a latch 44 and a spring 45 permanently urging the latch towards a hole 41, formed in this case in coincidence with that 42 of the wall 40a.
  • the latch 44 protrudes, by its other end, of the housing 43, and by a hinge 46, is hinged to one of the ends of a connecting rod 47 whose other end is coupled, by an axis 48, to the end of one of the branches of a bent lever 49, articulated around an axis 50 on a tab 52 of the chassis 4, as shown in FIGS. 1, 3 and 4.
  • the other branch 49a of lever 49 is arranged so that its end is in the engagement path of the pin 8 of one of the rolling means, by example the right one, and comes into contact with the end of this tenon 8, when its engagement in the bearing 7 to ensure by the connecting rod 47, the retraction of the latch 44 in its housing 43.
  • chassis 4 of the seat structure B comprises, in its front part, and projecting downwards, a ring 53 and, in its rear part, two lateral rings 54 also projecting downwards.
  • Cradle C is composed, as shown in detail in Figure 4, of a chassis 60, from the rear part of which two guide flanges 62 project of the ends of the axle 5 of the seat structure.
  • This chassis carries, the front, a double bearing 63 in which a shaft is mounted to rotate freely transverse and horizontal 64, integral with a hook 65.
  • the lower end 65a of the hook is connected, by a transverse axis 66, to the rod 67a of a jack electric 67.
  • the shaft 64 is connected, by a lever 68, to a connecting rod 69 extending longitudinally backwards.
  • two bearings 70 carried by the flanges 62, guide in rotation a transverse and horizontal shaft 72 carrying two hooks 73.
  • This shaft is integral with a lever 74 whose free end is linked, by an articulation 75, to the longitudinal rod 69.
  • the cylinder 34 is again powered in the direction of vertical movement upwards of the assembly armrest structure 29 and this until this arm is at a level higher than the position of the cradle C.
  • the transfer structure C is re-engaged in the passenger compartment of the vehicle by carrying with it the seat structure and its occupant.
  • the arm 29 and the seat are inserted into the passenger compartment at closer to the door jamb, avoiding, as is the case in current devices, that the occupant is forced to contort to avoid his knees hit the padding 71 of the dashboard.
  • the electric actuator 34 is supplied in the direction of descent.
  • the ends of the axle 5 of the rear wheels cooperate with the upper profiles of the flanges 62 for position the seat structure longitudinally and transversely by relation to the cradle.
  • an element of the seat structure and for example one of the lateral wings 30b of the pallet 30, comes into contact with a contactor 75, arranged on the cradle, as shown in FIG. 4, and on the electrical supply circuit of the electric actuator 67.
  • This cylinder being supplied, it directly controls the tilting of the hook 65 and indirectly by the connecting rod 69, that of the hooks 73.
  • unlocking the hooks 65 and 73 that is to say the temporary supply of the electric actuator 67, is controlled by reverse direction by the manual control unit.
  • a other contactor not shown and cooperating with the connecting rod 69 or with one hooks 65, 73, detects this unlocking and triggers the supply of the vertical displacement cylinder 34 in the direction of elevation of the arm 29 by relative to cradle C.
  • the placement of the front wheel allows the lug 8 to take support on the branch 49a of the lever 49, and consequently generate the movement causing the retraction of the lock in its casing 23 by releasing the vertical finger 33.
  • the seat structure which in the interval was fitted with its other wheels, can be placed on the ground, then detached from the pallet 30.
  • the locking of the seat structure on the pallet is controlled by the removal of one rear wheels.
