ABSTRACT:
A shampoo chair for positioning its occupant comfortably for a shampoo at a shampoo bowl includes a base which rests on a floor in front of the shampoo bowl and has tracks, a carriage which moves along the tracks of the base, a fluid-operated cylinder which is mounted on the carriage, and a chair form which is supported on the cylinder and has a seat panel over which a seat cushion lies and a back panel to which a backrest is attached. The carriage gives the chair form horizontal movement toward and away from the shampoo bowl, while the cylinder elevates the chair form generally vertically. Between the two movements the chair form may be positioned to accommodate individuals of varying stature to the shampoo bowl. The carriage is provided with a carriage lock which includes eccentric elements that lie over the tracks. When the elements are turned, they bear against the tracks and prevent the carriage from moving along the base. In the alternative, the locking elements may be mounted on the base, so that when they are turned, they bear against the carriage.
