Abstract
A telescopic lifting column (1) preferably for furniture, such as height adjustable tables and beds, and comprising at least two mutually telescopic members (2,3,4) and an electric drive unit (5, 10;41,42) for adjusting the telescopic members. The lifting column comprises a telescopic cable guiding device (22;45, 58, 80, 103) for guiding at least one electric cable (29), where the telescopic cable guiding device extends between or in all essentials between the lower and upper end of the lifting column and is connected thereto so that the telescopic cable guiding device collaborates in the telescopic adjustment of the lifting column. Thus the cables may be guided in a protected manner.
