摘要： A suspension unit includes a lower frame, an upper frame vertically movably mounted on the lower frame, and two link mechanisms disposed on respective sides of the upper and lower frames for connecting them to each other. Each of the two link mechanisms includes a parallel link mechanism having two arms extending generally parallel to each other and a pantograph-shaped link mechanism having a plurality of arms. The suspension unit further includes two permanent magnets each fixedly mounted on one of the upper and lower frames with like magnetic poles opposed to each other, a metallic spring engaged with one of the pantograph-shaped link mechanisms, and a shock absorber engaged with the other of the pantograph-shaped link mechanisms that has spring properties. With such construction, vibration below a predetermined amplitude is absorbed by the spring properties of the other of the pantograph-shaped link mechanisms with the shock absorber not operated.

摘要： A vibration mechanism having a magnetic spring includes a lower frame, an upper frame vertically movably mounted on the lower frame via a plurality of link mechanisms, and at least two permanent magnets mounted on the lower frame and the upper frame, respectively, with the same magnetic poles opposed to each other. A plurality of springs are connected to the link mechanisms to produce a lifting force of the upper frame. The total spring constant of the permanent magnets and the springs is partially set to a negative value or substantially zero.

摘要： A seat or bed partly includes frames 8, 14 and net-shaped skins 10, 16 held by the frames 8, 14 under tension, respectively. Each of the net-shaped skins 10, 16 is made of an upper mesh layer 24, a lower mesh layer 26, and a pile layer having a large number of piles 28 that connect the upper and lower mesh layers 24, 26 to each other. Each pile 28 is made of a single string.
