Abstract

See full text

A compact and failsafe magnetorheological energy absorber design including both a light weight piston (LWP) embodiment in which linear motion is subjected to a linear damping force, and a light weight rotary vane (LWRV) embodiment in which linear motion is converted into rotary motion and is subjected to a rotary damping force. Both embodiments allow increased damper stroke within a compact mechanical profile. A new lightweight Magnetorheological energy attenuation system (LMEAS) for a vehicle seat is also disclosed using the new LMRW MREA.
