The chassis side structure has a front door (1) and a rear door (3) that are arranged in vehicle longitudinal direction (x). An intermediate column (B) is not arranged between the front and rear doors. The reinforcing elements (15,17) are respectively integrated in the front door and rear door, for protection against a side collision. The reinforcing elements are joined together to form a deflector (19). The front and rear doors are clamped between a front column (5) and a rear column (11).
