1. A bodywork frame for a motor vehicle, in particular a passenger car, comprising two lateral load bearing columns, which are supported on each other, at a roof side, via a pressure-stable roof cross member and, at a floor side, on a longitudinal tunnel, in each case via a pressure-stable seat cross member, wherein each load bearing column has a column-like hollow body, and wherein a tubular element, which extends substantially in a longitudinal direction of the load bearing column, is arranged within said column-like hollow body. 2. The bodywork frame according to claim 1, wherein each of the seat cross members is additionally supported on the other via a pressure-stable bridge beam, which bridges the longitudinal tunnel. 3. The bodywork frame according to claim 2, wherein at least one of the roof cross member, the seat cross member, and the bridge beam has a pressure-stable hollow profile. 4. The bodywork frame according to claim 1, wherein the load bearing columns are B columns. 5. The bodywork frame according to claim 1, wherein the tubular element is formed from at least one tube of a high-strength material and having a constant cross section. 6. The bodywork frame according to claim 1, wherein at least one of the roof cross member and the seat cross member has a pressure-stable hollow profile. 7. The bodywork frame according to claim 2, wherein the load bearing columns are B columns. 8. The bodywork frame according to claim 3, wherein the load bearing columns are B columns. 9. The bodywork frame according to claim 6, wherein the load bearing columns are B columns. 10. A process of providing a bodywork frame for a motor vehicle, in particular a passenger car, ensuring increased side impact protection comprising: providing two lateral load bearing columns, and supporting the two lateral load bearing columns on each other, at a roof side, via a pressure-stable roof cross member and, at a floor side, on a longitudinal tunnel, in each case via a pressure-stable seat cross member, wherein each load bearing column has a column-like hollow body, and wherein a tubular element, which extends substantially in a longitudinal direction of the load bearing column, is arranged within said column-like hollow body. 11. The process according to claim 10, and further comprising additionally supporting the seat cross members on each other via a pressure-stable bridge beam, which bridges the longitudinal tunnel. 12. The process according to claim 11, wherein at least one of the roof cross member, the seat cross member, and the bridge beam has a pressure-stable hollow profile. 13. The process according to claim 10, wherein the load bearing columns are B columns. 14. The process according to claim 10, wherein the tubular element is formed from at least one tube of a high-strength material and having a constant cross section.
