Abstract

Afin d'en faciliter l'utilisation, des sièges, chaises et fauteuils peuvent être dotés de coussins, de dossiers et d'appui-jambes inclinables, articulés et à ressorts. On peut régler l'inclinaison et/ou l'effet de ressort à l'aide de vis ou de barrettes. On utilise un dispositif de blocage pour immobiliser le siège ou analogue dans la position voulue. Afin d'abaisser rapidement le siège, le dossier ou l'appui-jambes, on peut utiliser un variateur de vitesse permettant l'enclenchement ou le désenclenchement du point d'application de la puissance (du siège) et/ou de la résistance aux ressorts.
