Abstract

A progressive gas spring device, designed e.g. for drivers' seats in trucks. This device includes a gas spring (18, 18c), a gas-tight vessel (5, 5c) as well as between the gas spring and the vessel, a pneumatic connection (9a, 9b, 9c), which comprises elements (14, 3, 3c), designed to maintain said pneumatic connection, when the strokes of the spring are moderate, and to disconnect said pneumatic connection, when the strokes of the spring are larger.
