- the connection wires 22 selectively supply the excitation coil 27 with a current of command noted i.
- the magnetic member 20 is integrated in the backrest 19 in such a way that the permanent magnet 24 faces the element 21 made of magnetic material when the passenger 17 is seated.
- FIG. 2 illustrates the first example of a safety system when the magnetic member 20 is placed in a state of attraction, which state is controlled when the seat 10 is outside the landing areas.
- the control current i is zero and the excitation coil 27 is not energized.
- the permanent magnet 24, by generating a magnetic field resulting in attractive forces F, attracts the element 21 in magnetic material.
- the onboard passenger 17 is firmly held by the back. The risks of accidental fall of the passenger 17 by sliding towards the front below the bar 15 are completely removed, regardless of the position of the railing 13.
- Figure 3 shows the system of Figure 2 when the magnetic member 20 is put into a release state, which state is controlled when the seat 10 passes into a landing area.
- the current source disposed in the station supplies the excitation coil 27 with a non-zero control current i via the pick-up device and the connection wires 22, after a possible passage in an on-board electronic filtering circuit.
- the excited electromagnet 25 generates a magnetic field that compensates for the magnetic field created by the permanent magnet 24.
- the attraction forces F are zero and the element 21 is released in order to be able to move in a direction of movement D. away from the backrest 19.
- the passenger 17 is released and can disembark.
- the magnetic member 20 and the element 21 of magnetic material constitute magnetic means capable of occupying a retaining position of a passenger 17 embarked on the seat 10 when the seat 10 is outside the landing areas, and a position of liberation when passing through a landing zone.
- FIGs 4 and 5 illustrate a second example of a security system, in which the magnetic member 20 is modified.
- the magnetic member 20 comprises an electromagnet 25 identical to that of Figures 2 and 3, but the permanent magnet 24 is removed.
- the connection wires 22 selectively supply the excitation coil 27 with a control current denoted i.
- the magnetic member 20 is integrated in the backrest 19 so that the ends of the branches of the core 26 are opposite the element 21 of magnetic material.
- the current source is, in this case, embedded on the seat 10 and includes accumulators and possibly an electronic processing circuit. Any means of recharging accumulators may be considered.
- the assembly is controlled by an onboard control unit (not shown).
- the capturing device is deleted.
- FIG. 4 illustrates the second example of a safety system when the magnetic member 20 is put in a state of attraction, which state is controlled when the seat 10 is outside the landing areas.
- the on-board control unit controls the current source so as to supply the excitation coil 27 with a non-zero control current.
- the energized electromagnet attracts the element 21 of magnetic material, generating in a known manner a magnetic field resulting in attraction forces F.
- the onboard passenger 17 is firmly held by the back. The risks of accidental fall of the passenger 17 by sliding forward below the bar 15 are completely eliminated, regardless of the position of the railing 13.
- FIG. 5 shows the system of FIG. 4 when the magnetic member 20 is put into a release state, which state is controlled when the seat 10 passes into an unloading area.
- the on-board control unit controls the current source so as to cancel the control current i.
- the electromagnet 25 no longer generates a magnetic field.
- the attraction forces F are zero and the element 21 is released to be able to move in a direction of movement D away from the backrest 19.
- the passenger 17 is released and can disembark.
- the control unit can communicate, for example by radio, with transmitters or sensors arranged in the stations so as to know at each instant the position of the seat 10 (in a landing zone or not) or at least the state to which the magnetic member 20 is to be controlled.
- the magnetic member 20 comprises only a permanent magnet 24 and the electromagnet 25 is removed.
- the permanent magnet 24 is mounted at the end of a rocker capable of moving it between a position remote from the element 21 of magnetic material with which it cooperates, and a close position, respectively when the Seat 10 is in an unloading area and outside the landing areas.
- the passage from the close position to the remote position makes it possible to increase the gap separating the permanent magnet 24 and the element 21 made of magnetic material sufficiently to reduce or even cancel the attraction forces F applied to the element 21 when the permanent magnet 24 is in close position. Conversely, the passage from the remote position to the close position makes it possible to reduce the air gap sufficiently to generate large attraction forces F in a close position.
- the movements of the rocker are actuated by any suitable control mechanism, mechanical or electrical, for example.
- the magnetic member 20 of the three variants described above can indifferently be integrated into the seat 18 of the seat 10.
- the element 21 of magnetic material with which it cooperates is integrated into the garment of the passenger 17 at the level of the buttocks and / or thighs.
- Some variants have magnetic members 20 simultaneously in the seat 18 and in the folder 19, as shown in Figure 1.
- the magnetic member 20 of the three variants described above is carried by the passenger 17 while the element 21 of magnetic material is secured to the seat 10. If the magnetic member 20 involves an electromagnet 25, the current source. generating the control current i, as well as the associated control unit, are integrated into the clothes of the passenger 17. The control communicates then, for example by radio, with transmitters or sensors arranged in the stations so as to know at any time the position of the seat 10 (in a landing area or outside the landing areas) or at least l state to which the magnetic member 20 is to be controlled.
- the element 21 of magnetic material can be mounted at the end of a rocker capable of moving it between a position remote from the permanent magnet 25 with which it cooperates, and a close position, respectively when the seat 10 is in a landing zone and outside the landing areas.
- any other equivalent means for constituting magnetic means according to the invention can be envisaged.
- any technology can be used to either compensate the magnetic field created by a permanent magnet 24, or to demagnetize the magnet 24, for example from a specific power supply.
- Element 21 of magnetic material ' can be integrated in the mesh of the fabric forming the clothing of the passenger 17. Further, the shape of the permanent magnet 24 and the electromagnet 25 may vary subject to maintain a similar operation.
- the invention covers all the materials, systems and mechanisms (mechanical, electronic, electrical, radio ...) associated with the magnetic member 20 and the element 21 so that the latter can operate in accordance with the invention.
- the element 21 is of any shape, advantageously ergonomic so as not to interfere with the passenger 17 when it is integrated into the clothing, and made of any suitable magnetic material (iron, cobalt, nickel, alloys of these magnetic materials with possibly non-magnetic compounds).
