Embodiments herein relate to a method and apparatus for vehicle (1) occupant (2) protection in unintentional roadway departure by a vehicle (1) having at least one vehicle seat (6) with a seat cushion (6a) mounted on a seat frame (6b), the height of which is adjustable through a motor operated height adjustment device (6c), and a vehicle comprising such an apparatus. Vehicle (1) travel is monitored using at least one of a remote sensor (3) and a vehicle dynamics sensor (4). The remote sensor (3), when present, at least detecting edges of the road (9). The vehicle dynamics sensor (4), when present, determining vehicle dynamics parameters. At least one of road edge signals (3a) and vehicle dynamics signals (4a) are processed to determine whether the vehicle (1) is about to leave the road (9). Operation of the height adjustment device (6c) to move a seat cushion (6a) towards a crash-position is triggered in response to an off-road signal (5a) indicating that the vehicle (1) is about to leave the road (9).
