A head and neck rest for vehicle seats comprises a head piece secured to a supporting rod which is mounted by the intermediary of an articulated joint on a saddle or supporting frame on the back rest of a seat. The joint allows a pivoting or tilting movement of the head piece and its supporting rod. A clamping rod traverses the joint and is arranged for exerting a predetermined clamping force on the members of the joint for controlling the tilting movement of the head piece due to the action of a shock received by the head or neck of a passenger, for example when the vehicle is hit in the rear by another vehicle driving in the same direction.
