Abstract

La présente invention concerne un module (10) d'ordinateur station de travail, de conception ergonomique, sans contrainte, qui peut s'adapter universellement à la plupart des claviers et des souris. Ce module comprend une découpe en forme se prolongeant en direction de l'opérateur de façon à lui offrir un support pour les avant-bras et les poignets confortable. Un plateau inférieur télescopique partant de dessous un élément plan supérieur coopère par articulation et glissement avec un plateau en pente réglable destiné à supporter un clavier. Ce dispositif fourni une position bio-mécanique solide permettant de placer une souris d'ordinateur de manière centrale. Cette invention offre une solution qui s'avère efficace et économique au problèmes liés au syndrome du canal carpien et à l'inclinaison cubitale.
