In one embodiment, a device is configured to counteract the occurrence of whiplash injury to a person sitting in a seat, which can occur due to a rapid change in velocity, such as in a rear-end collision. The device comprises guide means that, during a change in motion of a vehicle, provide for a change in position of the seat in the form of translation and rotational movement of the seat in a generally backward direction opposite the direction of travel of the vehicle. As the seat and the occupant of the seat move backward relative to the vehicle, the head of the occupant accelerates over a longer distance than the hips of the occupant.
