1. A lower-back supporting structure for a bed or a chair comprising:
a sliding base forming a rectangular frame, front ends and rear ends of two length-wise sides respectively having a pair of slide slots and a pair of rotating pins, a securing portion disposed on a down-extended portion between the two rotating pins, and the sliding base including a plurality of the locking apertures;
two scissor lifts both forming an X-shaped frame having a pivot, two bottom ends of each having a first front cotter hole and a rear cotter hole, two top ends of each having a second front cotter hole and rear rotating pin, the first front cotter hole of each scissor lift aligned with the slide slot of the sliding base, the rear cotter hole of each scissor lift pivoted to the rotating pin, and a sliding pin is placed through the two second front cotter holes of the two scissor lifts;
a driver having a positioning end, the positioning end pivoted to the securing portion of the sliding base, another end of the driver having an extendable rod and a through hole disposed at an end of the extendable rod, the through hole aligned with the slide slot of the sliding base; and a sliding rod is placed through the slide slot, the through hole and the first front cotter holes; and
a supporting member having four corners corresponding to the four top ends of the two scissor lifts, a pair of slide tracks and a pair of rotating holes, each slide track corresponding to the sliding pin, and each rotating hole pivoted to the rear rotating pins;
wherein the driver drives the sliding rod along the slide slot of the sliding base to shorten the extendable rod, the scissor lifts rotate around the pivots to lift such that the supporting member is pushed away from the sliding base.
