Abstract (en)
[origin: EP0521762A1] Column intended to be a part of a furniture support, in particular for a chair, and formed by a sliding tube (6) whose upper frustoconical end is intended to be fitted, by its upper part, into a matching frustoconical cavity in the upper part of the piece of furniture (5), which slides in a support tube (2) which is integral with a leg (3) of the piece of furniture. The sliding tube traps, with radial play, the body (7) of a gas spring, whose piston rod (9) is fastened to the bottom of the support tube (2). A reinforcing metal sleeve is force-fitted inside the frustoconical end part. Its lower edge (14) acts as a bearing surface for the upper edge of the body (7) of the gas spring. Advantageously, it consists of a split socket bearing a tongue which immobilises in rotation a thruster (19) inserted between the locking control finger (16) and an actuating lever (17). <IMAGE>
