1. A suspension device for a vehicle seat, comprising: an upper suspension portion and a lower suspension portion, said suspension portions being connected to one another by a first swivel connector and a second swivel connector, said first swivel connector being arranged on the lower suspension portion in such a way that said first swivel connector can swivel about a first swivel pin, and the second swivel connector being arranged on the lower suspension portion in such a way that said second swivel connector can swivel about a second swivel pin, a first tension spring and a second tension spring being respectively connected to the first swivel connector by a first end region and to the upper suspension portion or the lower suspension portion by a second end region,wherein the first end region of the first tension spring is attached to the first swivel connector at a first distance, and the first end region of the second tension spring is attached to said first swivel connector at a second distance, the length of the first distance being variable, wherein the first distance between the first end region of the first tension spring and the first swivel connector can be adjusted by an adjustment device, which is connected to the first swivel connector at one end and to the first end region at the other end. 2. The suspension device according to claim 1, wherein the second distance between the first end region of the second tension spring and the first swivel connector remains constant. 3. The suspension device according to claim 1, wherein the adjustment device comprises a first and a second support element, which are rigidly connected to the first swivel connector, a spindle element that can be rotated about a first axis of rotation, said spindle element being connected to a first spindle bearing and a second spindle bearing, said first spindle bearing being connected in a stationary manner to the first and second support element, and said second spindle bearing being connected to an adjustment member that can be rotated about a second axis of rotation, said second axis of rotation being mounted in such a way that it can rotate on the first and second support element, and the first end region of the first tension spring being connected to the adjustment member, and the first end region of the second tension spring being connected to the first support element. 4. The suspension device according to claim 3, wherein the adjustment device can be actuated by an actuating lever, which is connected to the spindle element by rotating the actuating lever about the first axis of rotation, as a result of which the adjustment member can be rotated about the second axis of rotation. 5. The suspension device according to claim 3, wherein the adjustment device can be actuated by an actuating member driven by a motor, said actuating member being connected to the spindle element, by rotating the spindle element about the first axis of rotation, as a result of which the adjustment member can be rotated about the second axis of rotation.
