    Abstract: A threshold-activated piston device with dampened response for use an aircraft seat, includes a chamber, a piston, a releasable fastener and a coupler, wherein the fastener is configured to release the piston for a stroke in response to an impact force that exceeds a predetermined threshold. The predetermined threshold may be set by a friction member, spring, a tension fastener, a check valve mechanism and/or a catch mechanism. Motion of the piston device resulting from the impact force imparted is dampened by conversion of kinetic energy into thermal energy. The method of energy conversion may be through, but not limited to, friction, viscous damping or velocity squared damping. The piston device may be configured for reuse in allowing the stroke to be reset. Additional fluid ports and/or a spring enables resetting of the stroke.

    Abstract: 簡易な構造で、相対変位量に応じた適切な減衰力を機能させる。 シリンダ2内を相対運動するピストン3の外周面に巻き付けられた線状部材32と、線状部材32に付着され、粘性減衰力を発揮する粘性流体とを有している。シリンダ2及びピストン3の相対運動により張力が生じ、振幅が小さいほど、線状部材32は、隣り合って巻き付けられた部位それぞれが該線状部材32自体の円周方向に沿ってねじれるように変形しようとし、振幅が大きいほど、隣り合って巻き付けられた部位同士が一体となった状態で変形しようとする傾向が強くなる。振幅が小さい場合には、摩擦抵抗の低下によってピストン3の運動がスムーズになり、粘性流体の粘性減衰力により、適切な減衰力が得られる。振幅が大きい場合には、線状部材32の隣り合って巻き付けられた部位が一体的に変形しようとする傾向が高まり、摩擦減衰力の作用が相対的に大きくなる。

    Abstract: A shock absorption device is comprised of an inner cylinder assembly threadably engaged within an outer cylinder assembly. The outer cylinder assembly includes a cap shaped member, at least one protruding member, and at least one first spring member. The inner cylinder assembly includes at least one compressive member, at least one second spring member, and at least one movable piston member. When an external impact force F1 is applied to the cap shaped body member, the first threaded portion of the outer cylinder assembly jumps over the second threaded portion of the inner cylinder assembly as provided by elastic movement of the resilient ring member about the cap shaped body member. The thread jumping results in the first spring member compressing and the protruding member pushing the piston member which pushes and compresses the second spring member and the compressive member providing a reactive force F2 to absorb the external impact force F1.
