Abstract

The invention relates to a functional seat headrest and discloses a simple, rapid and effective protection measure for preventing cervical vertebra whiplash injuries. Specifically, the headrest is mainly composed of a movable headrest body, a supporting headrest body and a trigger connecting rod mechanism. The movable headrest body can rotate relative to the supporting headrest body, and the supporting headrest body is fixed to a seat back through a supporting frame. The movable headrest body is hinged to the trigger connecting rod mechanism through a connecting rod and is mainly used for preventing the cervical vertebra whiplash injuries. The supporting headrest body is used for supporting the movable headrest body, and a protruding neck-rest part is arranged on the lower front portion of the supporting headrest body and used for supporting parts under head occipital bones and preventing cervical vertebra fatigue damages. The cervical vertebra protection measure is achieved through inertia triggering; and meanwhile, the protruding neck-rest part used for supporting necks is added to the headrest, heads of passengers are effectively supported, and cervical vertebra fatigue damages are reduced, so that riding comfortableness of the vehicle passengers is improved.
