Zusammenfassung:A free hinge drive system for a link of a vehicle seat such as a relaxation seat includes a first pinion gear of a motor and a second pinion gear of a brake device that are connected by an interconnection member, and a first sector gear gear-coupled to a first pinion gear and a second sector gear gear-coupled to a second pinion gear have symmetric shapes. In operation, a free hinge of the link is rotated by release of a braking force of the brake device during a relaxation operation, and the free hinge of the link is restrained by a braking force when the relaxation operation is not performed, thereby preventing lift of a second front height link corresponding to another side output (outer side) in the event of a rear collision, improving passenger safety, and minimizing forward and rearward movements of the vehicle seat.
