Abstract

Le présente invention concerne un dispositif amortisseur de choc pour une chaussure, le dispositif amortisseur de choc comportant : une chambre à air avant et une chambre à air arrière dans lesquelles un certain volume d'air est chargé ; et un profilé d'écoulement d'air qui connecte ladite chambre à air avant et la chambre à air arrière : la chambre à air avant et la chambre à air arrière se contractant et se dilatant de manière répétée tour à tour par pression dans une partie pied avant et par pression dans une partie pied arrière d'un utilisateur, agissant en alternance ; et ledit profilé d'écoulement d'air comportant un moyen de réduction en coupe du profilé d'écoulement d'air, permettant d'empêcher un écoulement soudain d'air en réduisant une coupe du profilé d'écoulement d'air si l'air s'écoule soudainement dans une direction. Selon la présente invention, si le poids de l'utilisateur est fourni sur un espace amortisseur de choc particulier dans lequel une certaine quantité d'air est chargée, l'air s'écoule selon un écoulement stable sans que l'air ne s'échappe rapidement vers un autre espace amortisseur de choc, pour ainsi augmenter la fonction d'amortissement de choc. Par ailleurs, étant donné que des parties saillantes d'acupression sont formées sur une surface de l'espace amortisseur de choc, le pied de l'utilisateur est constamment stimulé à des fins de diminution de la fatigue.
