Abstract
A telescopic tube for use in a linear drive to be applied in articles of furniture such as beds, chairs and the like has an outer tube accommodating an inner lift tube which is longitudinally displaceable within the outer tube by the linear drive and projects from the outer tube at a front end opposite to the linear drive. An end cover having a seal closes and seals the front end and prevents any media from entering the outer tube and the linear drive.
