Abstract

The invention provides a multiple-phase dynamic cushion comprising a frame, at least a driving source, at least a transmission assembly, and clusters of plural strips interleaved in parallel. Taking a two-phase embodiment as an example, the two-phase strips interleave with each other, in parallel, to form the cushion's surface and alternate their tensions in turn; when one phase's strips periodically tighten to support the user's body, the other phase's strips will loosen, allowing the user's body covered by the loosened strips to take a rest, averting a pressure-ulcer risk. The driving source is energized by an altering energy, making the two strip groups alternate in loosening and tightening states periodically in turn. This invention can be converted into a portable dynamic chair when the four holes on the bottom of its four corners are inserted with legs; it can also be converted into a dynamic support for a lying human body.

Description

technical field

[0001] The invention relates to the field of furniture, in particular to a dynamic seat cushion structure which can be used as a chair or as an independent seat cushion and can effectively prevent the occurrence of pressure sores. Background technique

[0002] Seat cushions currently on the market include various natural materials and seat cushions made of artificial materials such as foam, gel, water bladders, and air bladders. Their structures are static and their surfaces are mostly difficult to breathe. After the user sits for a long time, the buttocks / pubic area often feel uncomfortable due to the accumulated moisture. The small blood vessels in the skin in this area will be oppressed for a long time and will gradually block and become ischemia, which will cause the skin in this area to feel hot and uncomfortable. If the pressure is not relieved for a long time, it will cause skin itching and eczema in mild cases, and in severe cases Can develop pressur...

Embodiment Construction

[0054] In order to enable your examiners to clearly understand the content of the present invention, the following descriptions are provided together with the drawings, please refer to them.

[0055] two-phase embodiment

[0056] see figure 1 , Figure 2A , Figure 2B , image 3 and Figure 4 , is a three-dimensional structure diagram of the two-phase embodiment of the present invention, and various structural schematic diagrams, top views and front views of another embodiment thereof. As shown in the figure, the description of the present invention is consistent with the direction definition of the scope of the patent, that is: when facing the front of the seat cushion, the front and rear direction of the seat cushion is called "longitudinal", and our left and right direction Call it "horizontal". The present invention mainly includes a frame 1 , a power source 2 , a power transmission group 3 and a plurality of strip groups 4 representing multi-phases and interwoven in...
