Abstract
The invention relates to a load-bearing frame for a chair, in particular for an office chair, which can be adjusted in terms of its height and inclination and comprises a seat carrier (1), a backrest carrier (2), a load-bearing and pivoting device (80) and a standing column (5). By means of struts (46, 32) arranged on the knee side and backrest side and supported on a spindle body, the seat carrier and backrest carrier (1, 2) are mounted on a spindle body such that they can pivot about a horizontal axis (X), oriented transversely to the seat direction, against the restoring force at least of a first spring element (40, 40'), and, in any position, can be fixed, and released again, by a second spring element. On the standing column (5) there is arranged a retaining device (10) through which the spindle body passes in the horizontal direction and on which a bracing element (20), by means of which the restoring force of the first spring elements (40, 40') can be adjusted, is mounted such that it can pivot about a bolt (15).
