Abstract

Cette invention se rapporte à une chaussure absorbant les chocs, qui comprend : un élément supérieur qui enveloppe et protège le coup-de-pied et la cheville ; un coussinet qui est cousu à l'élément supérieur, qui améliore la force de friction entre la sole plantaire et le sol, et qui se compose d'une partie avant-pied et d'une partie talon ayant chacune un évidement d'une profondeur prédéterminée ; une unité de rembourrage qui est placée dans les évidements correspondants des partie avant-pied et talon du coussinet et qui est destinée à absorber les chocs pendant que l'utilisateur marche ou court ; une unité de pompage d'air qui est placée dans l'évidement de la partie talon, pour remplir une fonction de rembourrage auxiliaire et qui fournit de l'air sur la partie avant-pied ; et une semelle de fond qui est montée sur la partie supérieure du coussinet et à laquelle la sole plantaire de l'utilisateur est fermement attachée. Ainsi, on obtient un effet de rembourrage complémentaire mutuel sous l'action des ressorts hélicoïdaux et de l'unité de rembourrage auxiliaire, ce qui multiplie par deux l'effet d'absorption des chocs. Par conséquent, l'utilisateur qui porte cette chaussure ne subit aucun effort de contraintes au niveau du genou ou des articulations, ce qui en améliore la commodité d'utilisation et les possibilités de commercialisation.
