Seat belt system (10) for a vehicle including: a 3-point seat belt (12) that comprises a first section (12a) that is arranged to diagonally cross the chest of a vehicle occupant (14) and a second section (12b) that is arranged to cross the pelvis of a vehicle occupant (14), and a 2-point seat belt (16) that is arranged to diagonally cross the chest of a vehicle occupant (14) in a direction that crosses said first section (12a) of said 3-point seat belt (12) so as to form an X-shape. The seat belt system (10) also comprises a first locking means (24) that is arranged to lock said 2-point seat belt (16) when the force on said 2-point seat belt (16) exceeds a predetermined first force (F1), and a first force limiter (29) that is arranged to substantially maintain the force exerted by the 2-point seat belt (16) on the vehicle occupant (14) at said predetermined first force (F1). The seat belt system (10) also comprises a second locking means (26) that is arranged to lock said 3-point seat belt (12) when the force on said 3-point seat belt (F) exceeds a predetermined second force (F2), and a second force limiter (27) that is arranged to substantially maintain the force exerted by the 3-point seat belt (12) on the vehicle occupant (14) at said predetermined second force on the seat belt (F2). The predetermined first force (F1) is less than the predetermined second force (F2).
