<p>The chair has a lifting device with a support bar connected with a seat (101), and a bar hingedly connected with the support bar. A pivoting axis is hingedly connected with a firm bar element, and drive devices e.g. electro motors (150L, 150R) are pivotably arranged at the bar element. The drive devices move a spindle drive that is hingedly connected with the support bar, and another pivoting axis is arranged at a distance from the former pivoting axis. A pivot point of the drive devices is formed at the firm bar element, such that the drive devices are pivotable around a third pivoting axis.</p> |
