PROBLEM TO BE SOLVED: To provide a seat suspension that can withstand input vibration not only in a vertical direction but also in six-axis directions, and further has a compact constitution.SOLUTION: In a seat suspension, three sets of pantograph type links 11 are employed between the vehicle body floor side and the seat side. This enables a control in six-axis directions and allows the suspension to be constituted more simply than before. The seat suspension has an active control mechanism 10 employing the pantograph type links 11, and further has a compressed coil spring 21 and a magnetic spring 22 as a first and a second elastic members. Specifically, the seat side is controlled in an anti-phase to the vehicle body floor side by the active control mechanism 10 relative to an input direction of vibration and the vibration is passively removed by the elastic members so that the vibration can be removed with high efficiency. |
