The present invention relates to a cargo support comprising a pair of sections (1, 2), which are telescopically displaceable relative to one another, an actuator (6, 7) mounted on said sections (1, 2) in order to produce a relative movement of said sections, and locking means (5) for blocking the sections in the desired relative position. The characterising features of the invention are that the actuator comprises a gas spring (6, 7) and that the locking means comprises a shut-off valve (5), which is connected with the gas-actuated spring and which, when in its closed position, locks the gas-actuated spring (6, 7) in the then position of said spring but when in its open position allows expansion and contraction of said spring (6, 7).
L'invention concerne un appui au transport du marchandises comprenant une paire de segments (1, 2) qui se déplacent de façon télescopique l'une par rapport à l'autre ; un actionneur (6, 7) monté sur ces segments (1, 2) et permettant de produire un mouvement relatif de ces segments, et un moyen de verrouillage (5) permettant de verrouiller les segments dans la position relative souhaitée. L'invention est caractérisée en ce que l'actionneur comprend un ressort à gaz (6, 7) et le moyen de verrouillage comprend une valve de fermeture (5) raccordée à un ressort à gaz. En position fermée, cette valve bloque le ressort à gaz (6, 7) dans la position actuelle et, en position ouverte, elle permet l'expansion ou la compression de ce ressort (6, 7).
