The relative position worked in coordination for limiting and adjusting the two；Wherein unidirectional locking groove 331 allows lateral strut 33 to Forward
Dynamic, bidirectional locking groove 332 then limits that 33 front and back of lateral strut is irremovable, and its purpose is to headrest foaming 4 before preventing
Because maloperation is separated with rear headrest foaming 5.
The front end of lateral strut 33 is relatively fixed with fixing bolt 35 with support plate 34, and support plate 34 is used to support preceding headrest
Foaming.
When needing the upper and lower position to chair headrest to be adjusted, pass through the strut groove 211 and peace on left branching rod 21
Locking system (usually positive stop spring plate) on the headrest guide sleeve on motor vehicle seat back is worked in coordination, and headrest guide sleeve is passed through
On unblock button (or unlocker device of other forms) carry out height adjusting.
Locking system can be had in headrest guide sleeve, most common locking system is positive stop spring plate, such as patent
CN201720493081.2 discloses a kind of chair headrest guide sleeve, patent CN201420824278.6 discloses a kind of automotive seat
Headrest guide sleeve, patent CN200720068253.8 disclose a kind of automobile seat headrest guide sleeve etc.；Due to the relevant criterion of country
And the limitation of professional etiquette, standard in automobile industry etc., it will be installed headrest guide sleeve on existing automotive seat, and this is practical new
Type is not related to the change of headrest guide sleeve structure, therefore does not occur headrest guide sleeve in the accompanying drawings.
When needing to adjust the horizontal position of chair headrest forward by taking the gear after as an example, i.e., as shown in Figure 3.This
When apply external force and 4 be pulled along the foaming of preceding headrest, the drive lateral strut 33 of support plate 34 in preceding headrest foaming 4 is to Forward
It is dynamic, at this time since the locking baffle 312 on locking elastic slice 31 is worked in coordination with the unidirectional locking groove 331 of lateral strut 33,
It is not hindered so being pulled along.Headrest foaming 4 before unclamping after adjusting to suitable position, locking spring 32 is by locking elastic slice 31
On locking baffle 312 in lateral strut 33 unidirectional locking groove 331 or bidirectional locking groove 332 work in coordination, will before
The position of headrest foaming 4 is fixed；
When needing the horizontal position to chair headrest to adjust backward, since unidirectional locking groove 331 or bidirectional locking are recessed
The limitation of slot 332 can not directly promote preceding headrest foaming 4 immediately rearward.So pressing solution firstly the need of external force is applied
Button 37 is locked, so that the unidirectional locking groove 331 or bidirectional locking groove 332 in locking baffle 312 and lateral strut 33 are mutual
After disengaging, headrest foaming 4 is moved backward before capable of just making, and after being adjusted to suitable position, unclamps unblock button 37, locking spring 32
Locking baffle 312 on locking elastic slice 31 is worked in coordination with the locking groove in lateral strut 33, by the position of preceding headrest foaming 4
Set fixation.
The above embodiments of the present invention is not the restriction to scope of protection of the utility model, the reality of the utility model
It is without being limited thereto to apply mode, all this kind above content according to the present utility model, according to the ordinary technical knowledge of this field and used
With means, under the premise of not departing from the utility model above-mentioned basic fundamental thought, the utility model above structure is made its
The modification, replacement or change of its diversified forms, shall fall within the scope of the present invention.
