Abstract
A seat for use in a vehicle has a squab and a seat-back element, the seat-back element is mounted so that when the vehicle is subjected to a rear impact, initially the lower part of the seat-back element moves rearwardly relative to the squab and relative to the upper part or head-rest provided on the seat, so that the head of the occupant of the vehicle is brought into contact with the head-rest. Subsequently, the entire seat-back may move rearwardly, for example by pivoting about an axis defined by the recliner mechanism.
