Abstract

La présente invention concerne une machine d'exercice conçue pour augmenter la flexibilité et permettre un étirement contrôlé des muscles du torse. La machine comprend un coussin matelassé sur lequel un utilisateur est situé en position assise. La machine comprend en outre une traverse matelassée qui se déplace dans un arc circulaire contre lequel l'utilisateur pousse avec son dos, son thorax, ou son côté, suivant la position assise. La traverse soutient et guide l'utilisateur par l'intermédiaire d'un mouvement arqué complet depuis une position verticale vers le bas dans la direction du sol. La machine comprend un deuxième coussin stationnaire qui soutient la région du bassin ou de la taille d'un utilisateur pendant la thérapie d'étirement. Les positions de la traverse et du coussin stationnaire sont réglables afin de s'adapter à la taille de l'utilisateur. L'appareil d'exercice utilise une série de ressorts compensés logés dans une enceinte principale pour permettre à l'utilisateur de retourner aisément à une position assise.
