Specific embodiment
Be referred to attached drawing Fig. 1~Figure 10 below and word content understand the contents of the present invention and the present invention with it is existing
Distinctive points between technology.Hereafter attached drawing and by way of enumerating some alternative embodiments of the invention, to of the invention
Technical solution (including optimal technical scheme) is described in further detail.It should be understood that any skill in the present embodiment
Art feature, any technical solution are the technical characteristic or one or more of optional technical solution of plurality of optional, in order to
Description it is succinct need all alternative technical characteristics of the invention impossible to exhaust and alternative technical side in this document
Case, the embodiment for being also not easy to each technical characteristic emphasize it for one of optional numerous embodiments, so this field
Technical staff should know: any technological means provided by the invention can be replaced or by provided by the invention any two
A or more technical means or technical features, which are combined with each other, obtains new technical solution.Any skill in the present embodiment
Art feature and any technical solution do not limit the scope of the invention, and protection scope of the present invention should include this field
Technical staff does not make the creative labor the thinkable any alternate embodiments of institute and those skilled in the art will be of the invention
Any two or more technical means or technical features of offer technical solution new obtained from being combined with each other.
It is not easy clamp hand, folding convenient and safety and can more preferably interlock to fold the embodiment of the invention provides a kind of
Stroller seat.
Technical solution provided by the invention is illustrated in more detail below with reference to Fig. 1~Figure 10.
As shown in Fig. 1~Figure 10, the stroller seat folded, including backrest can be interlocked provided by the embodiment of the present invention
Pipe (or: handle pipe) 1, mounting pipe 3, interlocked folding mechanism and limitation locking mechanism.
It is flexibly connected between the seat portion that the backrest portion that backing tube 1 is formed is formed with mounting pipe 3 by interlocked folding mechanism,
Backrest portion and seat portion are made backrest portion and seat portion front around active connection place and are connected far from but with the close direction in the seat portion back side
Turn is dynamic to be folded, which folds the portion without the armrest or similar armrest that are clipped between backrest portion and seat portion
Part not will form clamp hand gap, so the problem of clamp hand is also not present.And the back-to-back process that folds is limited in default model
In enclosing.
In addition to this, expansion seat portion can be interlocked during backrest portion is unfolded to be formed seat configuration, be rendered as seat
The use angle of setting.From between the front that Fig. 1~Figure 10 can be seen that the backrest portion and both seat portions in collapsed position
Angle be greater than backrest portion and both seat portions in an open position front between angle.
Therefore the backrest portion and seat portion provided in an embodiment of the present invention for interlocking the stroller seat folded
Opening state either is turned to from folded position, or turns to folded position without going past being clipped in backrest from opening state
The component of armrest or similar armrest between portion and seat portion, so not will form clamp hand gap, and then will not
Clamp hand, so improve the safety in utilization for the stroller seat that can be converted into.
