Gas spring suspension unit e.g. for seats - allows adjustment by switching over valve without changing length setting

摘要

A fluid volume (34, 42) is supported on the group (12) and when the valve (48) is open stands in pressure-transferring connection with at least one elastically pliable reaction face (40). In this balanced state of the piston/piston rod group, the valve (48) can be converted into a second position, i.e. closed, so that at least one closed partial volume (34) supported on the group (12) is removed from the pressure-transferring connection. The elastically pliable reaction face (40) is formed by the boundary face (40) between the fluid volume and a gas volume, which (boundary face) can be formed by a displaceable partition (40). USE - Gas spring suspension unit for seat.
