Specific embodiment
Be referred to accompanying drawing Fig. 1～Figure 10 below and word content understand present disclosure and the present invention with it is existing
Distinctive points between technology.Hereafter accompanying drawing and enumerate the present invention some alternative embodiments by way of, to the present invention
Technical scheme (including optimal technical scheme) is described in further detail.It should be noted that：Any skill in the present embodiment
Art feature, any technical scheme are one or more in the technical characteristic or optional technical scheme of plurality of optional, in order to
Description is succinct need in presents cannot the exhaustive present invention all alternative technical characteristic and alternative technical side
Case, the embodiment for being also not easy to each technical characteristic emphasizes that it is one of optional numerous embodiments, so this area
Technical staff should know：Any two for arbitrary technological means that the present invention is provided being replaced or providing the present invention
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 are not limited the scope of the invention, and protection scope of the present invention should include this area
Technical staff does not pay the thinkable any alternate embodiments of creative work institute and those skilled in the art by the present invention
Any two of offer or more technological means or technical characteristic technical scheme new obtained from being combined mutually.
Embodiments providing a kind of tong, folding convenient and security of being difficult can more preferably interlock what is folded
Stroller seat.
The technical scheme that the present invention is provided is illustrated in more detail with reference to Fig. 1～Figure 10.
As shown in Fig. 1～Figure 10, what the embodiment of the present invention was provided interlocks the stroller seat for folding, including backrest
Pipe (or claim：Handle pipe) 1, 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 that is close to the seat portion back side connect
Dynamic rotation is folded, and the 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 not there is a problem of tong yet.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 be formed seat configuration, seat is rendered as
The use angle of setting.Between the front that can be seen that both back-rests and seat portion in collapsed position from Fig. 1～Figure 10
Angle more than the angle between the front of both back-rest and seat portion in an open position.
Therefore, the back-rest and seat portion for interlocking the stroller seat for folding provided in an embodiment of the present invention
Either turn to open mode from folded position, or folded position is turned to without going past being clipped in backrest from open mode
The part of armrest or similar armrest between portion and seat portion, 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 be converted into.
