Specific embodiment
Be referred to accompanying drawing Fig. 1～Figure 10 below and word content understand present disclosure and the present invention with existing
Distinctive points between technology.Hereafter by accompanying drawing and enumerate the present invention some alternative embodiments by way of, to the present invention's
Technical scheme（Including optimal technical scheme）It is described in further detail.It should be noted that：Any skill in the present embodiment
Art feature, any technical scheme are all one or more of the technical characteristic of plurality of optional or optional technical scheme, in order to
Description is succinct, and need in presents cannot all alternative technical characteristic of the exhaustive present invention and alternative technical side
Case, the embodiment being also not easy to each technical characteristic all emphasizes that it is one of optional numerous embodiments, so this area
Technical staff should know：Any two arbitrary technological means that the present invention provides being replaced or the present invention being provided
Individual or more technological means or technical characteristic are combined mutually and obtain new technical scheme.Any skill in the present embodiment
Art feature and any technical scheme all do not limit the scope of the invention, and protection scope of the present invention should include this area
Technical staff does not pay the creative work thinkable any alternate embodiments of institute and those skilled in the art by the present invention
Any two providing or more technological means or technical characteristic be combined mutually obtained from new technical scheme.
Embodiments provide and a kind of be difficult tong, folding convenient and safety and more preferably can interlock to fold
Stroller seat.
Illustrated in more detail with reference to the technical scheme that Fig. 1～Figure 10 provides to the present invention.
As shown in Fig. 1～Figure 10, what the embodiment of the present invention was provided interlocks the stroller seat folding, including backrest
Pipe（Or claim：Handle pipe）1st, mounting pipe 3, interlocked folding mechanism and limitation locking mechanism.
It is flexibly connected by interlocked folding mechanism between the seat portion that the back-rest that backing tube 1 is formed is formed with mounting pipe 3,
Back-rest and seat portion around active connection place make back-rest and seat portion front away from but the direction close with the seat portion back side even
Dynamic rotation folds, and this gearing folds the portion without the armrest being clipped between back-rest and seat portion or similar armrest
Part, will not form tong gap, so also there is not tong.And the back-to-back process that folds is limited in default model
In enclosing.
In addition, expansion seat portion can be interlocked during back-rest launches to form seat configuration, so that seat is rendered as
The use angle setting.Can be seen that from Fig. 1～Figure 10 and be between the back-rest of collapsed position and the front of seat portion
Angle be more than angle between back-rest in an open position and the front of seat portion.
Therefore, the back-rest interlocking the stroller seat folding provided in an embodiment of the present invention and seat portion
Either turn to open mode from folded position, or turn to folded position all without going past being clipped in backrest from open mode
Armrest between portion and seat portion or the part of similar armrest, so tong gap will not be formed, and then also will not
Tong, so improve the safety in utilization of the stroller seat that can convert into.
