A vehicle impact protection system ( 10 ) includes a vehicle outer wall ( 16 ), a vehicle inner wall ( 14 ), the vehicle outer wall ( 16 ) and the vehicle inner wall ( 14 ) defining a mounting space ( 18 ) between them, and an elongated reinforcing profile ( 20 ) housed in the mounting space ( 18 ) and having a profile longitudinal axis (A), the reinforcing profile ( 20 ) being connected with an actuator device ( 28 ), an activation of the actuator device ( 28 ) leading to a change in curvature of said profile longitudinal axis (A) such that the profile longitudinal axis (A) is curved more intensively outwards towards the vehicle outer wall ( 16 ) after the activation of the actuator device ( 28 ) than before the activation. In one embodiment, an activation of the actuator device ( 28 ) leads to a change in curvature of the profile longitudinal axis (A) such that the profile longitudinal axis (A) is curved more intensively outwards towards the vehicle outer wall ( 16 ) after the actuator device ( 28 ) has been activated than before the activation. In another embodiment, the reinforcing profile ( 20 ) has different section moduli transverse to a rotation axis (B) which runs through a first fastening point ( 22 ) and a second fastening point ( 24 ) of the reinforcing profile ( 20 ), the actuator device ( 28 ) being able to swivel the reinforcing profile ( 20 ) about the rotation axis (B) starting from an initial position, such that the section modulus of the reinforcing profile ( 20 ) from the vehicle outer wall ( 16 ) towards the vehicle inner wall ( 14 ) is greater after the activation of the actuator device than in the initial position.
