<p>A columnar air belt-type gas spring comprising a spring body. The spring body is constituted by multiple columnar air belts (1) having a pressurized gas accommodation cavity. The columnar air belts (1) are connected at the upper and lower ends thereof to a positioning element (2). The pressure of a gas within the accommodation cavity is adjustable. The columnar air belt-type gas spring adjusts the softness and firmness thereof by filling in a pressurized gas, has the advantages of a large deformation range and of great horizontal and vertical ventilations, is applicable in manufacturing mattresses, sofas, massage chairs, and seats, allows for easy dehumidification, thus eliminating adverse effects to the human body, provides convenient softness/firmness adjustment and the large unidirectional deformation range, thus meeting requirements of various scenarios, allows for real-time adjustments, thus increasing the level of comfort, and is convenient to be packaged by being rolled up, thus conserving transportation costs.</p> |
