Embodiment
In actual production process, the draw-in groove 14 of pole 2 has three, when needing the height of regulation headrest when, by head
Pillow up moves, and headrest stay 2 is relative down, and one end of upper and lower locating piece 6 and draw-in groove 14 snapping can be along pole 2
Sidepiece sequentially enters in draw-in groove 14, and is positioned by draw-in groove 14, due to opening that the top employing of draw-in groove 14 tilts upward
Mouthful so that headrest can be moved upwardly by, and each draw-in groove 14 is a gear of height of headrest, when needing the height of headrest
The when that degree resetting, it is necessary first on gear when headrest is adjusted to the highest, afterwards headrest is up moved,
Alignment pin up and down 10 on headrest stay 2 can collide with the extension of upper and lower locating piece 6 so that up and down locating piece 6 around
Steady pin 23 rotates up and down, and upper and lower locating piece 6 lower end departs from the draw-in groove 14 of pole 2, and reset steel wire 8 is along with fixed up and down
Position block 6 rotates and moves down so that headrest up-down adjustment unlocks, afterwards due to the uprighting spring 9 on upper and lower alignment pin 10
The produced elastic force of compression, headrest can be moved on upper and lower alignment pin 10 when of reset by elastic returning, promotes reset steel
The upper end kink of silk 8 is collided with noise reduction cushion block 13 lower end, reset steel wire 8 moves and pulls upper and lower locating piece 6 to rotate,
Upper and lower locating piece 6 is made to complete locking with draw-in groove 14 snapping by the elastic force of upper and lower back-moving spring 12.
When headrest is under the effect of compression spring, when head rest body working of plastics 5 can down move, in order to avoid reset steel wire 8
Noise is produced with head rest body working of plastics 5 collision, so installing in head rest body working of plastics 5 upper end with upper and lower alignment pin 10
The noise reduction cushion block 13 corresponding with upper and lower alignment pin 10 front end.
Before and after needs regulation headrest during position, need to be moved along headrest, the when of mobile before and after locating piece 7 end
A mobile position on boss 18 both sides lines groove 20, when headrest is adjusted to position foremost when, again by head
Pillow is moved along so that front and back locating piece 7 departs from boss 18 both sides under the pressing of spacing preiection 19, now the most fixed
Position block 7 is in released state, by front and back regulating the elastic force of extension spring 11, is returned to by headrest on script position, Qian Houding
The arcwall face of the arc-shaped limit boss 21 on the lug bosses at end part 18 of position block 7 is collided, under the effect of front and back's back-moving spring 15
Locating piece 7 and boss 18 both sides lines groove 20 buckle again front and back.
