Patent ID: 8256838

Claim:
An active headrest comprising: a guide bar installed at an upper side of a seat back; a pair of sliders that are slidable on the guide bar upwardly and downwardly; a moving bar pivotably coupled to the sliders so that the moving bar is pivoted around the guide bar forwardly and rearwardly; a front cover coupled to an upper side of the moving bar; a pivoting guide unit pivoting an upper side of the moving bar forwardly as the sliders are raised toward the guide bar; a driving spring providing an elastic force for pushing the sliders upwardly; and a latch unit maintaining a state where the sliders compress the driving spring and are fallen, wherein a stay rod is installed at the upper side of the seat back, and the guide bar is integrated with the stay rod, and wherein the sliders are slidable on the stay rod upwardly and downwardly, and the front cover is coupled to the moving bar by a friction pivoting bracket that surrounds an upper side of the moving bar elastically and generates a friction force between the moving bar and the friction pivoting bracket so that the moving bar is pivoted around the stay rod forwardly and rearwardly.
