A motor vehicle (1) has a seat (7), a seatbelt (8), a deflector (5), longitudinal and vertical guide rails (2, 4), and first and second guide elements (3, 9). The seatbelt (8) is configured to secure a person seated in the seat (7) and is deflected by the deflector (5). The first guide element (3) is guided displaceably in a longitudinal direction (L) of the motor vehicle (1) in the longitudinal guide rail (2). The vertical guide rail (4) is fastened to the first guide element (3) and is displaced upon displacement of the first guide element (3). The second guide element (9) is guided displaceably in a vertical direction of the motor vehicle (1) in the vertical guide rail (4). The deflector (5) is fastened to the second guide element (9) so that the deflector (5) also is displaced upon displacement of the second guide element (9).
