PCT No. PCT/SE89/00344 Sec. 371 Date Aug. 12, 1991 Sec. 102(e) Date Aug. 12, 1991 PCT Filed Jun. 16, 1989 PCT Pub. No. WO90/07070 PCT Pub. Date Jun. 28, 1990.A gas-spring arrangement includes a gas-spring which has a substantially tubular, external casing (2) and a rod (3) which is guided for axial movement in the casing, between two terminal positions and is dampened by means of gas constrictions. The gas-spring includes attachment links at each end for attachment of the gas-spring between mutually movable devices or structures, such as a pivoted hood on a sunbed. The gas-spring arrangement includes a friction device (6) which is operative to brake the relative axial movement between the gas-spring casing (2) and the gas-spring rod (3), and also to fix the casing (2) and the rod (3) in selective relative positions, i.e., positions between the terminal positions, and when combined with a hooded sunbed, can maintain the hood in a desired raised position. |
