Abstract
A head-rest arrangement for a vehicle seat includes a head-rest mounted in position on a vehicle seat so that it can move forwardly from an initial position to a final position. A spring mechanism is provided to move the head-rest. A release mechanism is actuated by movement of a pressure responsive element within the back of the seat to initially prevent operation of the spring mechanism, and to release the spring mechanism when pressure is applied during a rear impact.
