Abstract

La présente invention concerne un dispositif automatique de protection contre les chutes pour personnes âgées, le dispositif comprenant une ceinture de taille gonflable (2), un tube de raccordement (3), une soupape (4), une corde de traction (5), un récipient d'air (7) et un capteur de gravité (8). Le tube de raccordement (3) est relié à la ceinture de taille gonflable (2). La corde de traction (5) est reliée à la soupape (4). La soupape (4) est reliée au tube de raccordement (3) et au récipient d'air (7). Le capteur de gravité (8) est prévu sur la surface du récipient d'air (7). Le capteur de gravité (8) est utilisé pour détecter l'accélération du dispositif automatique de protection contre les chutes pour personnes âgées. Un dispositif de commande (70) est prévu à l'intérieur du récipient d'air (7). La corde de traction (5) est utilisée pour tirer la soupape (4) afin d'entraîner l'air dans le récipient d'air (7) pour qu'il s'écoule dans la ceinture de taille gonflable (2). Le dispositif de commande (70) est électriquement connecté à la soupape (4) et au capteur de gravité (8), et est utilisé pour commander l'ouverture de la soupape (4) lorsque l'accélération du dispositif automatique de protection contre les chutes pour personnes âgées est égale à l'accélération gravitationnelle, de telle sorte que l'air dans le récipient d'air (7) s'écoule dans la ceinture de taille gonflable (2). Grâce au gonflage de la ceinture de taille gonflable (2) avec le récipient d'air (7), la présente invention réduit une force d'impact d'une chute sur un utilisateur, ce qui empêche ainsi l'utilisateur d'être blessé et facilite la protection en cas de chute accidentelle.
