On the base of the upper carriage, a roller width motion motor is fixed, the rotation shaft of which is connected to the roller width motion reduction gear, which is connected to the corresponding crank mechanism, which through the connecting rod is connected to the plane of the support arm of the massage rollers. Also, on the base there is a motor for forward movement of rollers, the rotation shaft of which is connected to a reduction gear for forward movement of rollers, which is connected by the moment of rotation to the shaft of rotation of gear wheels displacing the rollers forward. At the same time gear wheels are located on toothed racks, which are fixed perpendicular to base of upper carriage. Also, on the base of the upper carriage there is a motor for displacement of the carriage, the rotation shaft of which is connected to the reduction gear of vertical movement of the carriage, which is connected by the moment of rotation to the rotation shaft of toothed-round wheels located at the ends of the shaft. On both sides of the base of the lower carriage there are freely rotating wheels. Also described is a second version of the massage carriage for the massage chair.
