Further, in the utility model in another feasible embodiment, those skilled in the art can also be according to need It wants, saves the first lock banking stop 322 and the second lock banking stop 332, and the edge of the first strip-shaped hole 321 is arranged to snap-fit into Structure in one lock groove 2111, and the edge of the second strip-shaped hole 331 is arranged to snap-fit into the second lock groove 2121 Interior structure.

As shown in Figure 7 to 9, the first spring 34 and second spring 35 are tension springs, the both ends of the first spring 34 respectively with 32 hook joint of pedestal 31 and the first sliding component, the both ends of second spring 35 respectively with 33 hook joint of pedestal 31 and the second sliding component.

In addition, those skilled in the art also can according to need, the first spring 34 and second spring 35 are arranged to pressure spring, Crimp the both ends of the first spring 34 with pedestal 31 and the first sliding component 32 respectively, make the both ends of second spring 35 respectively with base Seat 31 and the second sliding component 33 crimp.

With continued reference to Fig. 7 to Fig. 9, it is provided with buckle on operating member 36, is provided on pedestal 31 for accommodating the card The strip-shaped clamp groove of button.Operating member 36 is inserted into after pedestal 31, and described to snap onto the strip-shaped clamp groove interior and being capable of edge The strip-shaped clamp groove length direction sliding.

To carry out the automotive seat of the utility model and the working principle of locking device 3 below with reference to Fig. 8 and Fig. 9 detailed Explanation.

As shown in figure 8, in a latched condition, the first slide bar 211 passes through the first pore structure 311 and the first strip-shaped hole 321, the Two slide bars 212 pass through the second pore structure 312 and the second strip-shaped hole 331.First spring 34 tenses the first sliding component 32 to the left, makes First lock banking stop 322 sticks into the first lock groove 2111, by 211 axial lock of the first slide bar.Second spring 35 tenses to the left Two sliding components 33 stick into the second lock banking stop 332 in second lock groove 2121, by 212 axial lock of the second slide bar.At this point, Headrest 2 is locked into fixed height, cannot move up and down.

It is not difficult to find out that, have between the first sliding component 32 and the second sliding component 33 are at lock position from Fig. 8 There is certain gap, to interfere the first sliding component 32 and the second sliding component 33 will not each other, Neng Goufen The first slide bar 211 and the second slide bar 212 are not locked.

When the operating member 36 in Fig. 8 is pressed, when moving right, operating member 36 can overcome the bullet of the first spring 34 Power, the first sliding component 32 of driving move right.After the first sliding component 32 and the second sliding component 33 to move right offsets The elastic force of second spring 35 can be overcome, the second sliding component 33 of driving moves right.Until the first sliding component 32 and second Sliding component 33 all slides into unlocked position shown in Fig. 9.

As shown in figure 9, in the unlocked state, the first lock banking stop 322 is separated with the first lock groove 2111, the second lock banking stop 332 separate with the second lock groove 2121, and the axial lock of the first slide bar 211 and the second slide bar 212 is released from.At this point, user can Move up and down it by pulling headrest 2.

When user will rest the head on 2 adjust to appropriate height when, unclamp operating member 36, the first sliding component 32 and operating member 36 are restored to lock position under the action of the first spring 34, by 211 axial lock of the first slide bar.Second sliding component 33 is It is restored to lock position under the action of two springs 35, by 212 axial lock of the second slide bar.Therefore headrest 2 is also locked into current Highly.

It will be appreciated to those of skill in the art that the first sliding component 32 and the second sliding component 33 can be made to keep In the case where lock position, the first spring 34 and second spring 35 can also be substituted by any other feasible holding member, Such as elastic slice, air bag, cylinder etc..Alternatively, those skilled in the art can according to need, the first spring 34 and second spring are saved 35, so that the first sliding component 32 and the second sliding component 33 oneself is maintained at lock position.Illustratively, in the first sliding Groove is respectively set on component 32 and the second sliding component 33, it is respectively corresponding in the first sliding component 32 and the second sliding component 33 Lock position at protrusion is respectively set.When corresponding protrusion is embedded into corresponding groove, the first sliding component 32 and Two sliding components 33 are locked to lock position respectively.

Based on description above, locking device 3 is fixed it will be appreciated to those of skill in the art that the utility model passes through Ground is installed in seat body 1, for traditional be installed to locking device on headrest 2, can be effectively reduced headrest 2 Complex degree of structure reduces the volume of headrest 2, so that headrest 2 is arranged to the shape created an aesthetic feeling by those skilled in the art.Together When, the utility model is by being arranged to component independent of each other for the first sliding component 32 and the second sliding component 33, so that One sliding component 32 and the second sliding component 33 can be non-interference the first slide bar 211 and the second slide bar 212 are carried out respectively Locking prevents the first slide bar 211 and/or the second slide bar 212 from occurring relative to locking device to make each slide bar all be locked 3 shaking, and then avoid the shaking of headrest 2.

Although in addition, do not showed that in figure, in the utility model in another feasible embodiment, art technology Personnel can also be as needed, fixes the pedestal 31 of locking device 3 using other any feasible connection types with seat body 1 To together.For example, pedestal 31 is made directly to weld, be threadedly coupled or be riveted together with the skeleton of seat body 1.Alternatively, ability Field technique personnel can also be be made into integration pedestal 31 and the skeleton of seat body 1.

Further, those skilled in the art also can according to need, and locking device 3 is installed on headrest 2.

So far, it has been combined preferred embodiment shown in the drawings and describes the technical solution of the utility model, still, this Field technical staff is it is easily understood that the protection scope of the utility model is expressly not limited to these specific embodiments.? Under the premise of the principles of the present invention, those skilled in the art can make equivalent change to the relevant technologies feature Or replacement, the technical solution after these changes or replacement are fallen within the protection scope of the utility model.
