Abstract

La présente invention se rapporte à une attelle de protection d'articulation (1), comprenant un premier élément (2) pouvant être fixé sur la face supérieure d'un avant-bras permettant la stabilisation du poignet ou la face arrière d'une cuisse permettant la stabilisation de l'articulation du genou ou la face interne du coude d'un bras supérieur permettant la stabilisation de l'articulation du coude, un second élément (3) pouvant être fixé, correspondant au premier élément (2) en termes de stabilisation d'articulation, sur la face supérieure d'une main permettant la stabilisation du poignet ou la face arrière d'une jambe inférieure permettant la stabilisation de l'articulation du genou ou la face interne du coude d'un avant-bras permettant la stabilisation de l'articulation du coude, et un élément mobile de liaison de type articulation (4) entre le premier élément (2) et le second élément (3), des dents et/ou des pointes (6) étant disposées sur le premier élément (2) pouvant être fixé et sur le second élément (3) pouvant être fixé, dans chaque cas sur le côté dirigé vers l'élément de liaison (4), ces dents et/ou pointes (6) étant mutuellement orientées par rapport au premier élément (2) pouvant être fixé et au second élément (3) pouvant être fixé de sorte que, lors de la flexion du premier élément (1) au second élément (2), elles viennent en butée l'une contre l'autre dans l'élément de liaison (4) et lors de la butée, en commençant à partir d'un angle de flexion maximal prédéfini des deux éléments, se bloquent les unes les autres, et une flexion/hyperextension ultérieure est empêchée/bloquée. L'invention se rapporte en outre à une utilisation de l'attelle de protection d'articulation (1) comme attelle fournissant la protection contre la flexion/l'hyperextension du poignet ou attelle fournissant la protection contre la flexion/l'hyperextension de l'articulation du genou ou comme attelle fournissant la protection contre la flexion/l'hyperextension de l'articulation du coude.
