摘要:
Height adjustable object carrier column for use as a chair column of a revolving chair. The head area of the chair is moved back to a rest height and angular orientation with respect to the foot area of the chair upon relief of the chair load. The head area can be adjusted with respect to the foot area, by height adjustment apparatus, to different rest heights. Height adjustment is provided in the form of a hydraulic or a hydropneumatic or a spring-hydraulic or a pneumatic actuator with a cylinder assembly and a piston rod assembly which are coaxial to a telescope axis. The height adjustment apparatus includes internal biasing structure and first arbitrarily adjustable and second automatic blocking devices, whereby following a reduction of the load on the object carrier column, the second blocking device is released, and the height adjustment apparatus is moved toward a specified limit position, and the stop moves the object carrier column into the specified rest angular orientation.
