SEDENTARISM-PREVENTING DESK CHAIR

The invention relates to a work chair used by individuals working exclusively at a desk or a computer, individuals who are exposed to a long assumed immobility of the their own body, facing the risk of occurrence and onset of effects specific to sedentary lifestyle. According to the invention, the chair consists of a seat (1) supporting the weight of the human body while working at a desk in the sitting position, which also has the role of imparting the human pelvis an oscillating rotation movement in the horizontal plane, with a small angle of 10° in one sense and 10° in the opposite sense, two semi-belts (12) clamped with one end onto a back rest (10) by means of some hooks (11), the semi-belts (12) being passed below the armpits and joined in front of the chest through a buckle (13), aiming at suspending the human body when the seat (1) is lowered at its back part, upon an electric command, two handles (19) which allow the user's body to be lifted by a few centimeters, using the force of his own arms, and detached from the seat (1), by resting his hands on these handles (19), a weight sensor (24) being placed under the seat (1) to transmit information to an electronic circuit, the weight of the human body sitting on the seat (1) being measured and displayed on a display device (25) placed on one of the elbow rests (16), the weight value displayed decreasing when the human pelvis partially or totally detaches from the seat (1), the display (25) offering number indications on the extension force applied to the spine. Invenţia se referă la un scaun de lucru utilizat de către persoanele a căror muncă se desfăşoară exclusiv la o masă de birou sau la un calculator, persoane care se expun unei imobilităţi îndelungate, asumate, a corpului uman propriu, cu risc de apariţie şi instalare a efectelor specifice sedentarismului. Scaunul conform invenţiei se compune dintr-un şezut (1) care susţine greutatea corpului uman în lucrul la birou în poziţia şezând, având şi rolul de a imprima bazinului uman o mişcare oscilantă de rotaţie în plan orizontal cu un unghi mic de 10° într-un sens şi cu 10° în sens invers, două semicenturi (12) prinse cu un capăt de un spătar (10) cu ajutorul unor cârlige (11); semicenturile (12) se petrec pe sub subsuori şi se unesc la piept printr-o cataramă (13), în scopul suspendării cu ele a corpului uman, atunci când şezutul (1) este coborât de partea lui din spate la o comandă electrică, două mânere (19) care permit ridicarea cu forţele braţ
