The invention relates to a safety system for motor vehicles having sensor devices for detecting an accident and an apparatus for reinforcing a carrying construction (1) of a motor-vehicle roof (6), in particular the A, B or C column of the motor vehicle, which protrudes beyond a lower edge of a window opening (4), in which an inflatable reinforcing element (2) is deployed which is fastened to the carrying construction (1) and can be filled with gas via a gas generator (3) if corresponding sensor data are present. The invention also relates to a carrying construction (1) per se.

1. A safety system for a motor vehicle comprising: a vehicle pillar adapted to support at least a portion of a roof of the motor vehicle, the vehicle pillar carrying a rail defining an opening; anda metal inflatable reinforcing element coupled to an exterior of the vehicle pillar, the metal inflatable reinforcing element inflatable to at least increase a cross-sectional area thereof, the metal inflatable reinforcing element including a first portion retained within the rail and a second portion disposed outside of the rail;wherein the vehicle pillar is coupled between the roof of the motor vehicle and a chassis of the motor vehicle, and the vehicle pillar defines a longitudinal extension between the roof and a hood of the motor vehicle; andwherein the second portion defines a folded region expandable upon inflation from a folded orientation to an expanded orientation. 2. The system of claim 1, wherein the first portion of the metal inflatable reinforcing element defines a coupling element that mates with the opening defined by the rail to retain the metal inflatable reinforcing element in a deployment direction. 3. The system of claim 1, wherein the rail is a trapezoidal rail and the first portion of the inflatable reinforcing element is a triangular projection. 4. The system of claim 1, further comprising: a gas generator responsive to a signal to generate an inflation gas to inflate the metal inflatable reinforcing element, the gas generator disposed within a cavity covered by the hood of the motor vehicle. 5. The system of claim 4, wherein the metal inflatable reinforcing element comprises a folded metal cushion in fluid communication with the gas generator to inflate in a plurality of directions upon receipt of the gas. 6. The system of claim 4, wherein the metal inflatable reinforcing element comprises a folded metal cushion in fluid communication with the gas generator and folded in an accordion-like manner such that the metal inflatable reinforcing element deploys in one plane upon receipt of the gas. 7. The system of claim 4, wherein when inflated the metal inflatable reinforcing element extends between a lower edge of a window opening in the motor vehicle and the vehicle pillar. 8. The system of claim 4, wherein the metal inflatable reinforcing element is flat against the vehicle pillar in a un-inflated state, and has a shape including a partially circular portion and a trapezoidal portion when inflated. 9. The system of claim 1, wherein the metal inflatable reinforcing element inflates to surround the vehicle pillar. 10. The system of claim 1, wherein the rail carried by the pillar is trapezoidal in cross section including a closed first side adjacent the pillar and an opposing, open second side, and further wherein the first portion of the metal inflatable reinforcing element is generally triangular with a base having a length greater than the second side. 11. A safety system for a motor vehicle comprising: a vehicle pillar coupled between a roof of the motor vehicle and a chassis of the motor vehicle to support at least a portion of a roof of the motor vehicle, the vehicle pillar defining a longitudinal extension between the roof and a hood of the motor vehicle;a holder coupled to an exterior of a portion of the longitudinal extension, the holder defining an open channel;an inflatable reinforcing element received within the holder, the inflatable reinforcing element inflatable to reinforce at least the portion of the longitudinal extension of the vehicle pillar to absorb a bending torque present on the longitudinal extension in a roll-over collision, the inflatable reinforcing element including a first portion retained within the channel of the holder and a second portion disposed outside of the channel; anda gas generator responsive to a signal to generate an inflation gas to inflate the inflatable reinforcing element, the gas generator disposed within a cavity covered by the hood of the motor vehicle. 12. The system of claim 11, wherein the inflatable reinforcing element comprises a folded metal cushion in fluid communication with the gas generator to inflate in a plurality of directions upon receipt of the gas. 13. The system of claim 11, wherein the inflatable reinforcing element comprises a folded metal cushion in fluid communication with a gas generator and folded in an accordion-like manner such that the metal inflatable reinforcing element deploys in one plane upon receipt of a gas. 14. The system of claim 11, wherein the first portion of the inflatable reinforcing element mates with the holder to retain the inflatable reinforcing element in a deployment direction. 15. The system of claim 14, wherein the holder is a trapezoidal rail and the first portion of the inflatable reinforcing element is a triangular projection. 16. The system of claim 11, wherein when inflated the inflatable reinforcing element extends between a lower edge of a window opening in the motor vehicle and the vehicle pillar. 17. The system of claim 11, wherein the inflatable reinforcing element is flat against the vehicle pillar in a un-inflated state, and has a shape including a partially circular portion and a trapezoidal portion when inflated. 18. The system of claim 11, wherein the holder is trapezoidal in cross section including a closed first side adjacent the pillar and an opposing, open second side, and further wherein the first portion of the metal inflatable reinforcing element is generally triangular with a base having a length greater than the second side. 19. A safety system for a motor vehicle comprising: a vehicle pillar coupled between a roof of the motor vehicle and a chassis of the motor vehicle to support at least a portion of a roof of the motor vehicle, the vehicle pillar defining a longitudinal extension between the roof and a hood of the motor vehicle;a holder coupled to an exterior of a portion of the longitudinal extension, the holder defining an open channel;a gas generator responsive to a signal to generate an inflation gas, the gas generator disposed beneath the hood of the motor vehicle;a metal inflatable reinforcing element in fluid communication with the gas generator to inflate and deploy upon receipt of the inflation gas, the metal inflatable reinforcing element including a coupling element retained within the channel to positively hold the metal inflatable reinforcing element in a deployment direction; andwherein the deployment of the metal inflatable reinforcing element reinforces the portion of the longitudinal extension of the vehicle pillar and at least a portion of the vehicle pillar disposed between the hood of the motor vehicle and the chassis of the motor vehicle. 20. The system of claim 19, wherein the holder is trapezoidal in cross section including a closed first side adjacent the pillar and an opposing, open second side, and further wherein the coupling element of the metal inflatable reinforcing element is generally triangular with a base having a length greater than the second side. 21.
