Abstract (en)
[origin: WO2021126768A1] A shock absorbing system (128) for force attenuation, impact modification or reduction, employs an envelope (140) having a chamber (145) containing a first working fluid, the envelope deformable in response to the impulse to attenuate impact force. A plurality of resilient supplemental absorber elements (136, 138) dispersed within the chamber. The plurality of resilient supplemental absorber elements are deformable in response to the force to assist in attenuating impact force and provide additional resilient restoring force to return the envelope to a pre-impact shape. In alternative implementations, a unitary cell (128) for energy dissipation employs an envelope (140) having a chamber (145) containing a first working fluid and an inner element (150) contained within the chamber and having an inner chamber (152) containing a second working fluid.
