The support has a fastening part (2), a load-bearing part (3), and a spring system located between the fastening part and the load-bearing part to generate a constant bearing strength. The spring system includes a spring (5) for absorbing a load, a compensation device for compensating changing spring force over a support path and a pre-stressing device (7) for adjusting the compressing force of the spring. A correcting device (13) corrects the deviation of the pre-stressing force over the support path as the consequence of the changing pre-stressing force. |
