A head-rest arrangement (4) for a seat in a motor vehicle has a main part (6) and a front part (7). Releasable connection means are provided to connect the front part to the main part and to release the front part in response to a rear impact. A resilient spring (21) is provided to bias the front part (7) forwardly while simultaneously drawing air through non-return valves (24) into a chamber formed by a concertina tube (22) of which the spring forms a part. The front part (7) of the head-rest engages the rear of the head of an occupant of the seat, preventing the head of the occupant of the seat moving rearwardly relative to the torso of the occupant of the seat, thus minimising whiplash injuries.
