Embodiments herein relate to an apparatus and method for vehicle (1) occupant (2) protection in large animal (3) collisions. Objects forward of the host vehicle are monitored using at least one forward looking remote sensor (4) and object signals (4a) output. A velocity of the host vehicle (1) is determined and velocity signals (5a) output. The object signals (4a) and the velocity signals (5a) are processed to determine whether the host vehicle (1) unavoidably will suffer a collision with a large animal (3) while travelling at or above a threshold velocity and a collision signal is output (6a). Operation of at least one of a motor operated height adjustment device (7c), inclination adjustment device (7e) and longitudinal position adjustment device (7f) of at least one vehicle seat (7) is triggered to move at least one of a seat cushion (7a) and a backrest (7d) thereof away from a leading edge of a roof (1 a) of the host vehicle (1) in response to the collision signal (6a).
