Additionally a drive rail, namely a rope, is provided to drive the brush, on which one on the shaft The roller arranged on the brush runs, which thus drives the brush. This embodiment has the disadvantage in the fact that only one brush is available for use as a massage device. It is also disadvantageous that a drive taking place via a rope is prone to failure, is subject to high wear and a a positive connection between the drive roller and the rope is by no means guaranteed. It is too disadvantageous that the various pull ropes and also the actual drive rope for the rotary movement of the brush Attack on the side of the unit with the guide rope and thereby impair the function Tilting of the guide part is to be feared.

In another known massage device (DE-OS 24 29 808) a guide tube is provided in which a ίο Piston / cylinder unit is provided on which a brush is held on one arm, which has a separate Motor is driven. This at the guide for the brush unit is not very torsionally stable, because to achieve the massage effect, pressure is exerted against the brushes, which leads to tilting and clamping of the brush unit on the guide column komrcu. There is also a rotor drive not suitable for bathroom units via electrical energy, even with low voltage. Also the an-order the brush itself is not suitable for achieving a special massage effect.

In another such massage device (DE-GM 77 29 478), a motor is on the shaft of the brush arranged with changeover gear, wherein the drive engages in a rack, which is located inside a guide column is located. The rail serves to guide the brush unit and not directly to the Drive,, whereby the electrical cable necessary to power the motor is constantly dragged along will.

A brush unit is also known (US Pat. No. 3,042,949), in which a brush is pivoted back and forth on a crank mechanism, with a rotational movement also being possible.
The invention is based on the object of designing a massage device of the type mentioned at the beginning in such a way that a robust drive of the brushes is ensured while achieving an improved massage effect.

This object is achieved according to the invention in that the brush unit is driven in two opposite directions Has brushes which are each arranged on a shaft with a pinion and mounted in a housing, that the pinions engage in racks attached to the side of the guide column, and that the housing encloses the guide column.

An advantageous embodiment consists in that the piston, which is arranged on a piston rod, is fastened to a cross member which is connected to the housing with the aid of connecting rods.
According to another special embodiment it is proposed that stops for reversing the valve are provided on the cross member and the housing.

According to a further embodiment, it is also advantageous that in a housing cover accordingly The displacement path is provided with slots for the brushes to pass through and the brush bodies in protective housings are arranged, which have a guided in the slot approach.

Finally, according to a last embodiment, it is proposed that the guide column be attached to a wall bracket Is arranged adjustable in height.

The invention has the essential advantage that an automatically working, particularly stable and with simple constructive means built up massage device is present, with the two working in opposite directions Brushing a particularly good massage effect is achieved. The particular constructive advantage

also results from the fact that the KolbeiW cylinder unit is centered by the brush unit itself in connection with the guide column.
