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.
