The automobile headrest is characterized in that a headrest holder is arranged at the rear part of the headrest; the headrest holder is connected with the headrest support frame via a retracting mechanism capable of retracting in horizontal direction; a trigger mechanism is arranged on the backrest, and the retracting mechanism is connected with the trigger mechanism.
Description
Technical field
The present invention relates to a kind of headrest, relate in particular to a kind of car seat headrest.
Background technology
The car seat headrest that is located at the automotive seat top generally is to play the support occupant's head; the effect of alleviating fatigue; main is plays the effect that protection occupant's neck is avoided damaging when crashing; but the car seat headrest that generally uses can only carry out up-down adjustment according to the position of occupant's head at present; and can't level move forward; like this when automobile crashes; the occupant is under the effect of impulsive force; move with car seat headrest behind the head inertia and contact; though this moment, car seat headrest played the effect of supporting to occupant's head; protection to a certain degree occupant's neck; but often owing to move behind the inertia of occupant's head, occupant's neck is produced the phenomenon of whipping injury simultaneously and car seat headrest occurs.
Chinese patent " a kind of automotive headrest (CN101331035A) " discloses a kind of car seat headrest, described automotive headrest comprises having the strut that is used for fixing the vertical component effect on the seat, and with the interconnective horizontal part of described vertical component effect, horizontal guide frame is fixed in the horizontal part of described strut, ratchet slider is movably mounted in described horizontal guide frame, ratchet pawl locking or discharge described ratchet slider, extension spring makes the ratchet slider after moving return its initial position, and the ratchet spring provides pulling force for described ratchet pawl.Though this car seat headrest can move forward the headrest level according to occupant's needs; but this apparatus structure complexity; and can't be according to the needs of emergency case; automatically chair headrest is in time moved forward fast when especially automobile collision accident taking place; avoiding occupant's neck to be whipped injury, thus more effective protection occupant.
Summary of the invention
The present invention has overcome car seat headrest apparatus structure complexity in the prior art; can't be according to the needs of emergency case; when especially automobile collision accident taking place chair headrest is in time moved forward automatically fast; occur car seat headrest to occupant's neck produce whip injury shortcoming; provide a kind of simple in structure; be skillfully constructed; and can be according to emergency case; can be when especially automobile collision accident taking place automatically with chair headrest reach fast in time; avoiding occupant's neck to be whipped injury, thus a kind of car seat headrest of more effective protection occupant.
