Abstract (en)
[origin: US4899969A] A lockable elevating mechanism for the continuous adjustment of chair seats or the like comprises a guide tube, in which a length-adjustable, lockable gas spring is slidably guided. The piston rod of the gas spring is connected to the bottom plate of the guide tube. The housing of the gas spring is guided by means of a guide sleeve in the guide tube, the guide sleeve having a central carrying tube, in which slide sleeves are arranged with space. The carrying tube is surrounded by a carrying sleeve held in the guide tube. Thus a gas spring is obtained, on the one hand, which is free of bracing, resistant to wear and with good sliding qualities, and, on the other hand, the manufacturing of the guide sleeve is favorable in terms of material expenditure.
