Abstract:
1. A dynamic cushion, comprising: a frame; a driving source; a transmission assembly with a first and a second longitudinal strip-tail connector respectively connecting a first strip cluster representing a first, or odd, phase and a second strip cluster representing a second, or even, phase, via each corresponding strip cluster's tail, wherein said driving source's movements are converted into back-and-forth movements to drive said two strip-tail connectors evenly-spaced inside said frame and said two strip clusters are interleaved in parallel with said first strip cluster's head being fastened to said frame's one transverse side and said first strip cluster being transversely wrapped across said frame's top surface and other transverse side so as to fasten said tail of said first strip cluster to said first strip-tail connector and with said second strip cluster's head being fastened to said frame's said other transverse side and said second strip cluster being transversely wrapped across said frame's top surface and said one transverse side so as to fasten said tail of said second strip cluster to said second strip-tail connector, in order to produce periodic two-phase alternating tension and relaxation in said two strip clusters to avert any health hazards such as pressure ulcers.
