Spring device

A spring device for the motion drive of a movable component from a rest position into a displaced position, comprising:

• a preloaded spring configured to urge the movable component from the rest position of the movable component into the displaced position of the movable component, the preloaded spring is under a greater tension in the rest position than in the displaced position,
• a gas spring including a pressurized gas-filled cylinder filled with a gas under pressure, the cylinder having a first end closed by a first end plate and a second end closed by a second end plate, the gas spring further including an axially displaceable piston subdividing an interior of the cylinder into a first working chamber and a second working chamber, the first working chamber and the second working chamber being connected to each other via a restrictor, a first piston rod connected to the piston and extending through the first working chamber, the first piston rod being led to the outside of the cylinder through the first end plate in a sealed manner, the first piston rod having free end connectable to one of the movable component or a stationary component, and a second piston rod connected to the piston and extending through the second working chamber, the second piston rod being led to the outside of the cylinder through the second end plate in a sealed manner, wherein the first piston rod and the second piston rod have the same cross section, and
• wherein the piston interacts with the first end plate at the displaced position of the movable component and interacts with the second end plate in the rest position of the movable component.
