Title
(EN) SHOCK ISOLATOR AND ABSORBER APPARATUS
(FR) APPAREIL ISOLATEUR DE CHOCS ET AMORTISSEUR
Abstract
(EN)
An apparatus and methods for isolating and absorbing energy associated shock forces that are exerted upon an object is discloded. The apparatus generally has: a housing (36) defining an enclosure (38); at least one segment of non-liquid material (42) contained within the enclosure (38); and a piston (40) placed within the enclosure (38). When the shock or impact force is applied to either the piston (40) or housing (36), the piston (40) urges the non-liquid (42) material to pass or extrude through an aperture, orifice, channel or slot (44) located either within the piston or the housing. The non-liquid (42) material passes or extrudes through the aperture, orifice, channel or slot (44) in a direction that is generally transverse to the relative movement of the piston within the enclosure. The passage or extrusion of the non-liquid material through the aperture, orifice, channel or slot (44) absorbs or dissipates at least a portion of the energy attendant to the shock or impact force.

L'invention concerne un appareil et un procédé pour isoler et absorber l'énergie associée aux forces induites par les chocs, exercées sur un objet. Ledit appareil comporte généralement : un boîtier (36) définissant une enceinte (38) ; au moins un segment de matière non-liquide (42) placé dans l'enceinte (38) ; et un piston (40) installé dans l'enceinte (38). Lorsque la force du choc ou de l'impact est appliquée sur le piston (40) ou le boîtier (36), le piston (40) pousse la matière non-liquide (42) de sorte qu'elle passe dans une ouverture, un canal ou une fente (44) situé(e) dans le piston ou le boîtier, ou qu'elle en soit extrudée. La matière non-liquide (42) passe dans l'ouverture, l'orifice, le canal ou la fente (44), ou en est extrudée, dans un sens qui est généralement transversal au mouvement relatif du piston dans l'enceinte. Le passage ou l'extrusion de la matière non-liquide par l'ouverture, l'orifice, la canal ou la fente (44) permet l'absorption ou la dissipation d'au moins une partie de l'énergie associée à la force du choc ou de l'impact.
