An anti-tipping chair base has a central support member (2) with a generally upright axis, and a plurality of arms (3) that extend generally radially outwardly from the axis and each of which is provided with a caster (4). An outer end portion (3A) of the arm has a shape that curves downwardly around the caster to an end edge (3B) outwardly of the caster. As seen in plan, the outer end portion of the arm has side edges (3C) that diverge in a direction towards the end edge and between which the end edge extends generally normal to the radial direction of the arm. The end portions (3A) of the arm comprise support elements that contact a surface on which the base is disposed in the event that the base tips in use.
L'invention concerne un pied de siège anti-basculement comportant un support central dont l'axe est en règle générale vertical et une pluralité de bras qui, en règle générale, s'étendent radialement vers l'extérieur à partir de l'axe, chacun d'eux étant doté d'une roulette. L'extrémité extérieure desdits bras a une forme incurvée vers le bas entourant la roulette et se terminant par un bord terminal extérieur à la roulette. Comme l'indique le schéma, l'extrémité extérieure d'un bras est dotée de bords latéraux divergeants, orientés vers le bord terminal et entre lesquels ce dernier s'étend, en règle générale, perpendiculairement au rayon du bras. Les parties terminales des bras comportent des éléments supports qui s'appuient sur la surface où le pied de siège est posé lorsque celui-ci bascule.
