Meanwhile, the seat can be actively adjusted forwards and backwards, and can be suitable for various conditions by matching with a linkage adjusting mechanism.

In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a seat is against linkage structure, including backing back, the seat skeleton, sliding base, initiative regulation slide rail and PMKD, seat skeleton rear end is equipped with the regulator that is equipped with bilateral symmetry, be connected with the connecting rod middle part on the angle modulation ware, the connecting rod upside is connected to be backed the downside and is articulated in proper order and have first connecting rod, second connecting rod and third connecting rod, the third connecting rod is fixed with the sliding base rear end, second connecting rod middle part is articulated with the seat skeleton, seat skeleton slidable sets up on sliding base, sliding base sets up on the initiative regulation slide rail.

Furthermore, the bottom side of the seat framework is provided with a slide rail connected with a slide groove on the slide base.

Further, the angle adjuster controls the adjusting angle of the backrest and the seat framework to be 100-180 degrees.

Furthermore, the active adjusting slide rail is an electric active adjusting slide rail, and the motor controls the sliding base to slide and adjust on the slide rail.

To sum up, the utility model discloses possess following advantage:

the utility model discloses a configuration optimization makes the back slide forward through link gear at the back in-process cushion side slide of falling, both links for adjustable stroke strengthens, and user experience degree is high, and realization back row seat that can be complete is fallen completely.

FIG. 2 is an exploded view of the structure of the present invention;

fig. 3 is a schematic view of the linkage part structure of the present invention.

Detailed Description

The invention will be further described with reference to the following drawings and examples:

example 1:

referring to fig. 1-3, a seat back linkage structure comprises a back rest 1, a seat frame 2, a sliding base 3, an active adjusting slide rail 4 and a fixed bottom plate 5.

The seat framework 2 is slidably disposed on the sliding base, specifically, a sliding rail 22 is disposed on the bottom side of the seat framework 2 and connected to a sliding groove 31 on the sliding base 3, the sliding base 3 is disposed on an active adjusting sliding rail 4, the active adjusting sliding rail 4 is an electric active adjusting sliding rail, and the sliding base 3 is controlled by a motor to slide and adjust on the electric active adjusting sliding rail.

With reference to fig. 1 and fig. 2, the rear end of the seat frame 2 is provided with two symmetrically-arranged adjusters 21, the angle adjusters 21 are connected with the middle of the connecting rod 6, the connecting rod 6 is used as a main part of linkage transmission, the upper side of the seat frame is connected with the lower side of the backrest 1, and the seat frame is sequentially hinged with a first connecting rod 7, a second connecting rod 8 and a third connecting rod 9, namely, the tail end of the first connecting rod 7 is hinged with the front end of the second connecting rod 8, and the tail end of the second connecting rod 8 is hinged with the front end of the third connecting rod 9.

The third connecting rod 9 is fixed with the rear end of the sliding base 3, specifically, the tail end of the third connecting rod 9 is hinged with the rear end of the sliding base, and a fixed structure is formed.

The middle part of the second connecting rod 8 is hinged with the seat framework 2.

The working mechanism of the structure is further explained, the angle adjuster obtains power through the driving motor and can control the adjustment of the backrest 1 and the seat framework 2 at 100-180 degrees.

In the working process of the angle adjuster, the connecting rod 6 drives the first connecting rod to the third connecting rod to act, and under the action that the middle part of the second connecting rod 8 is hinged with the seat framework 2, when the angle is adjusted, the connecting rod is displaced, at the moment, the seat framework 2 is displaced in the sliding groove 31 through the sliding rail on the seat framework, namely, linkage adjustment is formed, and the adjustable stroke in the front-back direction can be increased under the condition that the installation space is not changed.

Moreover, the electric active adjustment slide rail 4 can realize the overall adjustment of the seat, and the linkage adjustment is more reasonably applied to the space in the vehicle under the condition that the active adjustment is not carried out.
