ABSTRACT:
A health bed capable of adjusting the spine curve of a human body mainly comprises a plurality of elevators. Each of the elevators includes a lower plate having several upholders extending therefrom wherein a motor is fixed on the center of the lower plate and the axle of the motor is a screw engaged with the middle of a motor-driven base such that the motor-driven base can be moved upward or downward by a drive of the screw. The upholders support the motor-driven base is disposed above the lower plate and supported by upholders. A plurality of elastic objects is disposed on the motor-driven base in which the elastic object has a sense stick inside and the sense stick penetrates out of the bottom of the motor-driven base. A height sensor lateral the base may thus measure a downside movement of the elastic objects. The height sensor and the motor are connected to a control circuit that actuates the motors to drive the motor-driven bases upwardly to a desired height by receiving signals from the height sensors. When a user lies on the bed, each of the elevators actively sustains the spine curve of human body, achieving a comfortable sleep.
