Abstract
An active headrest device, for a vehicle, provided with at least a headrest portion () supported, through rotation means (), by at least a support member () in order to allow the headrest portion () to swing between an extreme front and an extreme back position in respect to the vehicle. The device () comprises at least a pushing means () associated to at least a first elastic means () and which may be blocked or released by at least a swinging blocking arm () connected to at least an inertial mass (); in an active condition (A), the blocking arm () blocks the pushing means () in a retracted condition allowing the headrest portion () to swing between the extreme front and extreme back positions, and in which the first elastic means () transmits to the pushing means () an elastic force directed in the direction of the extreme front position of the headrest portion (), the inertial mass (), in case of a stress bigger than a predefined threshold in a front or back direction, causes the rotation of the blocking arm () which releases the pushing means () which, as a result of the elastic force of the first elastic means (), rotates and/or stops the headrest portion () in the extreme front position.
