Another advantage results The fact that the depth of the recess varies either step-wise or continuously, and thus the seat can be individually adapted to the needs of the user, with the possibility of regular acclimatization and adaptation to two-point seating due to the adjustability of the insert in a transition phase consists. In this way, an existing lordosis may be at least partially eliminated.

Abstract

L'invention concerne une surface de siège (3), destinée notamment à une chaise de travail, un siège de conducteur ou similaire. Cette surface de siège (3) présente un évidement central (14) dans la zone postérieure et est fixée sur un châssis inférieur (2). L'invention vise à créer une surface de siège (3) pouvant s'adapter à différentes façons de s'asseoir, et le cas échéant pouvant servir de surface permettant à l'utilisateur de s'entraîner à adopter une position assise à 'deux points d'appui'. A cet effet, l'évidement (14) peut être obturé au moins partiellement par un insert correspondant (13), de sorte que la différence de hauteur entre la surface de siège (3) et l'insert (13) puisse être modifiée progressivement et/ou de façon continue. L'introduction d'un insert (13) dans l'évidement (14) de la surface de siège (3) permet à une personne de s'asseoir dans une position préférée connue, à 'trois points d'appui', ou bien de s'entraîner à s'asseoir, de temps à autre, uniquement dans une position à 'deux points d'appui'.
