This wash basin can be fixed above the back for hair washing. and when it is not being used. it can be placed in the back. A channel system. usually of flexible tubing connects the wash basin to the interior of the back. which acts as a slop basin for the used water and communicates by piping with a sink which receives the water from the locality of the chair.  
  The invention relates to this type of chair. It has for its object to provide a hairdressers chair in the back of which there is a water tank connected to a pipe-line for the disposal of used water and equipped to receive a wash-basin, and also a shampooing scoop, the said basin being extractable from the tank and fixed above the back, the shampooing scoop being pivotedly mounted on the wash basin.  
  The accompanying drawings represent two embodiments of the invention.  
 FIG. I is a side view of one embodiment;  
  FIGS. 2 and 3 are respectively an elevation from the rear and a view from above of FIG. 1;  
 FIG. 4 is an enlarged view of detail A of FIG. I;  
  FIG. 5 illustrates the functioning of the detail of FIG. 4; and  
  FIG. 6 is a partial schematic side view illustrating an alternative embodiment.  
  The hairdressing chair represented in FIGS. 1-5 comprises a pedestal l on which there is a frame 2 carrying a seat 3, a back 4 and two arm rests 5. The back 4 is tiltable and its movements are effected by a mechanism not shown, controlled by a pedal 6 placed on the pedestal l.  
  The back 4 includes a water-right tank 7, the upper part of which is covered by a rocking cover 8 pivoted on a hinge 9, whilst the base 10 on the said tank is connected to a pipe line 11 for running off used water and passing into the pedestal 1. On the tank 7 are a hose ferruk 12 connected to a flexible pipe (not shown) and mixer taps 13 connected to hot and cold water pipes passing into the pedestal I and schematically shown at 14 (FIG. 3).  
  The upper part of the tank 7 carries a wash basin 15 open at its front end 16 (FIG. 4), which is located over the tank, the lateral walls 17 of which each carry a slotted bar 18, the rear end I9 of which is terminated by a transverse bar 20 forming a manoeuvring handle. Each of these bars has a guiding and positioning groove 21 closed at its two ends (FIG. 4) which can slide along a pin 22 fixed on a transverse partition 23 of the tank 7, this groove being rectilinear along a part of its length and curved along the remainder.  
  At the front end of the basin IS, a shampooing scoop 24 is pivoted on two pins 25 extending respectively to the inside of the lateral wall 17. In this way the shampooing scoop 24 can be tilted so that its contents flow into the basin 15, the rear part 24 of the shampooing scoop 24 being shaped to permit this movement. The  
 rear part of the base of the shampooing scoop 24 is located above the front part I6 of the basin 15.  
  The chair as shown is used as follows. When the wash basin 15 is not in use, the shampooing scoop 24 is turned in the direction of the arrow 27 (FIG. 5) so as to lie above the basin 15. The basin 15 can then be displaced by making the grooves 2I slide on the pins 22 of the partitions 23 of the tank 7, so that it follows a tra- 5 jectory in accordance with the arrows 28 and 29 to enter the tank 7 where it is retained by the closed ends of the groove 21. The cover 8 is then turned down against the tank 7.  
  When it is desired to use the chair for washing hair, the cover 8 is opened and the basin [5 is pulled out by the handle 20 from the tank 7. The basin I5 is pulled out of the tank, guided and positioned by the engagement of grooves 21 on the pins 22, in a direction against the arrows 28, 29, and it is then guided towards the rear of the said tank. The basin I5 now rests on the cover 8 of the tank 7, and the shampooing scoop 24 is pivoted towards the front of the back 4 (direction contrary to that of the arrow 27 of FIG. 5) to rest against the back. The assembly is now operational. During the hair washing operation, wash water runs out into the basin l5 and thence into the tank 7, from where is passes into the discharge pipe-line 11; also water running into the shampooing scoop 24 pours from the base 30 of this latter into the sink l5 and thence into the tank 7.  
  It is to be noted that the form of the guide and positioning grooves 21 such as are shown, is not limitative; these grooves can be entirely rectilinear or curved, in accordance with the relative proportions of the basin and of the tank.  
  It is likewise to be noted that although it has been indicated that the basin l5 rests on the cover 8 when it is ready for use and that this is preferable, it may be modified so that the basin rests on any other structure such as for example a console or a strand integral with the tank, or even on the upper edge of the tank.  
  When the basin is ready for use, its position with respect to the tank can be chosen at will by displacement of the grooves along the pins. Any change in the position of the basin 15 will effect a corresponding change in the position of the shampooing scoop 24, since this is pivoted on the basin I5 and rests on the back 4. It is thus possible to adjust the inclination of the shampooing scoop as well as its transverse position with respect to the back 4, so that it can be adjusted to suit any user.  
  The chair described is of simple and efficacious manufacture, since movements of the wash basin and of the shampooing scoop does not involve any mechanism susceptible to be fouled or corroded by water or wash products. Moreover it is easy to remove the basin and the shampooing scoop by lightly pushing the partitions 23 away from each other to disengage the pins 22 from the grooves 21. This permits cleaning of the tank 7 as well as the basin l5 and its shampooing scoop 24, or even replacement of these latter.  
  Whilst the structure described is preferred, it is not however, limitative. The basin and the shampooing scoop can be guided in any other suitable manner with respect to the tank. The basin and the shampooing scoop may be pivoted relative to a support sliding in the tank. In this case. the vertical displacement of the support in the tank would permit the basin and its shampooing scoop to slide in or out of the tank, and when they are out of the tank and the shampooing scoop is turned down, vertical displacement of the support would enable the inclination of the basin and the shampooing scoop to be varied.  
  FIG. 6 illustrates this arrangement. There is a back 4 of the chair and a tank 7 in which slides a support 40 presenting two lugs 41 between which are pivoted the basin and its down turning shampooing scoop 24, these latter pivoting between the lugs 41 on a shaft 25.
