Abstract
Impact absorption devices and methods for a vehicle's seat are provided. Devices comprise vertical support(s), energy absorbing element(s) hingedly connected to the seat and hingedly connected to the vertical support; and at least four rods hingedly connected to the seat and hingedly connected to the vertical support. The rods are positioned to geometrically guide a relative motion of the seat with respect to the vertical support upon impact, and to direct the impact energy absorption by the energy absorbing element(s). The rods may be configured according to prevailing spatial relations and required energy absorption with respect to expected intensities and directions of impacts. The devices may be configured with any energy absorption element(s), may be augmented by vibration damping or implemented using electromagnetic dampers.
