Abstract
A headrest assembly including a headrest pad having a front surface and side portions that are movable between a first position and a second position wherein the side portions are forward of the front surface of the headrest pad. A shift mechanism is provided for moving the side portion to the second position. A trigger is actuated in response to an impact that causes the shift mechanism to move the side portion from the first position to the second position. The headrest pad preferably has a central section that is flanked by right and left side portions. The side portions pivot on a shaft or hinge mechanism that includes a spring that biases the side portions toward the second position. The trigger is preferably a hook that is mounted on a slide secured to the headrest pad. A torsion spring is secured between the hook and the slide so that the hook may be displaced relative to the headrest pad when the impact exerts an inertial load to the headrest pad above a predetermined level. The right and left side portions may pivot independently relative to each other. A ratchet may be provided between the side portions and the headrest pad that permits the side portions to be locked in one of a plurality of angular positions relative to the headrest body. The headrest pad may alternatively have a central section that is flanked by right and left side portions that are shifted in a fore and aft linear direction independently relative to a central section.
