- One embodiment of this chair provides that the piston is linked to an axial rod on which the seat is placed, the position of the latter being adjusted by action on the dispenser to introduce water. under pressure in the cylinder by driving the water in it towards the wastewater network.
- the underside of the chair is provided with: - a return spring urging the chair forward, - means allowing the chair to slide relative to a plate linked to the axial rod at least one non-cable elastic connecting the chair to a fixed point, the upward movement of the plate causing the chair to move backwards.
- the underside of the seat has at least three rollers guided in rails provided in the plate.
- the plate has on its rear face a pulley for guiding the non-elastic cable.
- the footrest articulated with respect to the chair comprises a tray on which slides a support element, a jack being capable of pivoting the footrest between a retracted position in which the support element is superimposed on the plate and an extension position in which the support element is in line with the plate
- the support element is at its end close to the articulation relative to the armchair connected to a fixed point of the armchair by a cable circulating in a sheath fixed on the tray at its end furthest from the articulation by report to the chair.
- a spring ensures the return of the support element.
- Figure 1 is a side view with partial cutaway of a hairdresser chair incorporating the adjustment device.
- Figures 2 to 4 show a side view of an adjustment device during operation.
- Figures 5 and 6 are side views of an alternative embodiment of a chair using the adjustment device.
- Figures 7 and 8 are side views of a second embodiment of the adjustment device.
- Figures 9 and 10 are side views of a third embodiment of the adjustment device.
- Figure 11 shows a side view of an alternative embodiment of a chair incorporating the adjustment device.
- Figure 12 is a sectional view along XII-XII of Figure 11.
- Figures 13 and 14 show during operation an adjustable footrest.
- Figures 15 and 16 show two other applications of the adjustment device.
- Figure 1 shows an assembly for a hairdressing salon comprising a chair 2 and a tray 3 for washing the hair and a cylinder 4 acting on the chair.
- a base 5 receives the chair 2 and the tray 3.
- the evacuation pipe 6 for the waste water from the tank 3 is hidden inside the base 5. This pipe opens into a siphon 7.
- a three-way distributor 8 is also arranged inside the base 5.
- the distributor 8 controlled by a lever 9 comprises a supply path 10 connected to the public water network, a use path 11 connected to the jack 4 and a return path 12 connected to the siphon 7.
- the jack 4 comprises a cylinder 13 in which a piston 14 moves.
- An axial rod 16 is linked at one of its ends to the piston 14 and at the other of its ends to a plate 17 on which the seat 18 of the chair 2 rests.
- the axial rod 16 has a groove blocking the rod in rotation.
- the height adjustment of the position of the chair 2 is carried out as follows.
- the lever 9 of the distributor 8 is pushed into the position supplying the jack 2.
- the chair 2 on which a person is seated rises to a position in which the head of this person is at the level of the tank 3.
- the lever 9 of the dispenser is placed in a position shown in Figure 3 in which the water introduced into the cylinder 13 is blocked therein.
- Figure 4 shows the descent phase of the chair 2.
- the handle 9 is pushed into a position controlling the flow of water present in the cylinder 13 to the siphon 7 leading to the wastewater network.
- Figures 5 and 6 show an alternative embodiment in which the plate 17 comprises two parallel rails 19, oriented in the direction of the seat of the chair 2 and in which the underside of the seat 18 is provided with four guided rollers 21 in the rails 19.
- the seat 18 of the chair is, on the one hand, subjected to a restoring force by means of a spring 23, parallel to the rails 19 and, on the other hand, is connected by a cable 24 to the base 5, the cable 24 being guided by a pulley 25 located on the rear face of the plate 17.
- the traction spring 23 keeps the chair forward, that is to say in a position in which the chair is furthest from the tray 3.
- the latter is biased towards the rear, that is to say in a position approaching the tray 3 since the cable 24 has a fixed length.
- This alternative embodiment makes it possible to combine a vertical movement upwards and a horizontal movement back and forth. The combination of these two movements therefore brings the chair 2 closer to the tray 3.
- Figures 7 to 10 show two other embodiments of the actuator ensuring the height adjustment of the chair.
- the actuator comprises a flexible bellows 30, associated with the guide structure.
- the bellows 30 made of flexible elastomeric material is connected to the supply path 11 coming from the distributor 8.

- the plate 17 is connected by pivot links 36 to the lower plate 34 by four uprights 37, the two plates and the uprights thus forming a deformable parallelogram.
- FIG. 9 shows the bellows 30 in the low position. When the pressurized water is introduced into the bellows 30, the latter deploys and exerts a thrust on the plate 17 which moves in vertical and horizontal components while remaining parallel to the plate 34.
- FIGS 13 and 14 show this leg rest in detail. It includes a plate 30 articulated in rotation relative to the seat.
- the plate 30 is driven by a rod 16 projecting from a jack 4 operating as described above by pressurized water coming from the network of the water distributor.
- a support element 32 is superimposed on the plate 30.
- Slides having a structure such as that shown in section in FIG. 12 allow the support element 32 to slide relative to the plate 30 between a position in which the element the support 32 is above the plate 30 and an extension position in which the support element 32 is in the extension of the plate 30.
- the displacement of the support element 32 is achieved by a cable 34 connected to a fixed point of the chair and to one end of the support element closest to the axis of articulation.
- the cable 34 slides in a sheath 35, one end of which is located on the plate 30 near the axis of rotation 31 and the other end is situated at its end furthest from the axis of articulation 31
- a return spring 37 connected the support element to the plate.
- the leg rest 29 whose rotation causes an elongation adapts to the morphology of the person sitting on the chair and in particular avoids the drawback of known leg rests, the end of which reaches the level of the person's calves. sitting on the chair.
- the leg rest as described, on the contrary lengthens and thus supports all of the legs.
- the bellows can be provided with mechanical strapping.
- the invention thus provides a device for adjusting the position of objects such as the seat of a hairdresser's chair, in a particularly simple and reliable manner.
