The invention relates to a headrest for installation in vehicles, in particular in road vehicles. Headrests of the known type are attached to the backrests of the vehicle seats. The greater the inclination of the backrests, the greater the distance of the headrest from the head of the vehicle occupant. If the rear of the vehicle is rammed due to a rear-end collision, the heads of the occupants are thrown backwards against the headrests. The longer this distance of throw, that is to say the distance between head and headrest, the greater the impact of the head on the headrest. By means of a head rest which is independent of the backrests of the vehicle, which for example is attached to the roof of the vehicle, and can be adjusted in the longitudinal axis of the vehicle within a large range, this distance, that is to say the distance between the head of the vehicle occupant and the head rest - can be reduced to zero so that injuries are excluded. <IMAGE>
