A seat component to prevent whiplash injury during a rapid motion change of a vehicle comprises means allowing a displacement of the seat and a person sitting thereon backwards ( 22 ) in relation to the direction of movement at the motion change. These means comprise a body ( 11, 18 ) to be affixed to or being part of the seat, a slide element ( 16 ) affixed to the vehicle and being in guiding contact with said body to guide a translational displacement of the seat over a predetermined distance. It further comprises a trigger system ( 13 ) to detect a acceleration threshold, a release mechanism ( 14 ) controlled through the trigger system ( 13 ) to enable said translational displacement ( 22 ) and a damping component ( 17 ) to damp said translational displacement ( 22 ). The trigger system ( 13 ) opens the release mechanism ( 14 ) only upon detection of an acceleration value above a predetermined threshold. The NIC experienced when using a conventional seat can be reduced by 40% if said seat is equipped with the device according to the invention.
