  • Relaxation apparatus
    Patent number: 6695799
    Abstract: A relaxation apparatus which comprises a reclining chair for supporting thereon a whole body of a person who desires relaxation. The person resting on the reclining chair is cyclically vibrated at a frequency not higher than 25 Hz. A control is provided for controlling the vibrating device. The maximum absolute value of acceleration of the vibration produced by the vibrating device to vibrate the person supported on the reclining chair is not greater than 0.1 G. The control controls the acceleration in dependence on the frequency of vibrations outputted by the vibrating device such that the acceleration is small when the frequency of vibrations outputted by the vibrating device is low while the acceleration is large when the frequency of vibrations is high.
    Type: Grant
