Headrest system and method of adjusting a headrest

摘要

A headrest system comprises a headrest, a guide bracket to which the headrest is mounted and an actuator coupled to the headrest and the guide bracket. The actuator is configured to displace the headrest relative to the guide bracket. The actuator comprises a spindle transmission and a power drive coupled to the spindle transmission. The spindle transmission comprises a spindle and a spindle nut engaged with the spindle. The power drive is arranged in a cavity defined within an outer shell of the headrest.
