A movement structure for a vehicle's active headrest is provided to inject the headrest by using a spring for supporting a head part of a passenger even when a passenger having a different weight rides on a collided vehicle. A movement structure for a vehicle's active headrest includes a headrest(10), a piston housing(20), a piston(30), a stopper(40), and an operation wire. The headrest is divided into a front headrest(10a) and a rear headrest(10b). The piston housing is at center of a headrest fixing stay(6) and included in the rear headrest. The piston is inside the piston housing and is injected to front by elastic force of a spring(35). The stopper is at bottom of the piston housing and constraints front movement of the piston. One end of the operation wire connects the left and right frame of a seat back to top of the operation plate(2). Other end of the operation wire connects to the stopper. |
