Abstract (en)
[origin: EP0511500A1] In a blockable lifting device for the infinitely variable adjustment of a chair seat, a guiding tube (1) is provided, on whose end plate (5) a piston rod (10) of a longitudinally adjustable gas spring (8) is fixed. The guiding tube (1) is provided with an additional tube (20) which can be extended telescopically and is guided in a guiding bush (22) which is fixed in the guiding tube (1). The housing (9) of the gas spring (8) is also guided in a guiding bush (27) which is fixed in the additional tube (20). Provided between the guiding tube (1) and the additional tube (22) is a mechanical spring (26) which forces the additional tube (20) out of the guiding tube (1). <IMAGE>
