Title: CUSHION WITH ALTERNATING LOAD-BEARING PARTS
Abstract:
Disclosed is a cushion with alternating load-bearing parts, comprising a cushion housing (1), wherein an upper supporting seat board (2) and a lower supporting seat board (3) are arranged sequentially from the top to the bottom in the cushion housing (1). The upper supporting seat board (2) is provided with a plurality of through holes (21) between the upper surface and the lower surface, and the upper surface of the lower supporting seat board (3) is provided with a plurality of supporting protrusions (31), positioned in one-to-one correspondence with the through holes (21), and can run through the through holes (21) from the bottom to the top and protrude beyond the upper surface of the upper supporting seat board (2). The upper supporting seat board (2) and the lower supporting seat board (3) are respectively mounted one above the other in the upper opening of the cushion housing (1) in a slidable manner. A plurality of upper supporting seat board lead screws (22) and a plurality of lower supporting seat board lead screws (32) are arranged longitudinally in the cushion housing (1), and each of the upper supporting seat board lead screws (22) and the lower supporting seat board lead screws (32) matches a lead screw hole in the respective upper supporting seat board (2) and lower supporting seat board (3). An upper supporting seat board driving device (4) and a lower supporting seat board driving device (5) are arranged in the cushion housing (1). The cushion can alternate the compressed parts of the human body that are in contact with the cushion, so that the skin and muscle tissues of the load-bearing parts can take a rest, consequently, the pressure can be relieved, circulation can be improved, fatigue can be relieved, and physical health can be improved.
