[ detailed description ] of the utility model
The utility model is further described below with reference to the accompanying drawings:
as shown in fig. 1 to 11, the present utility model provides a child seat, which comprises a seat part 1, wherein a backrest part 2 capable of rotating around a first axis a is connected to the seat part 1, a leg rest 3 is rotatably connected to the seat part 1 around a second axis B, and a transmission assembly 4 capable of driving the leg rest 3 to rotate along with the backrest part 2 when the backrest part 2 rotates is arranged between the leg rest 3 and the backrest part 2.
This children's seat can switch between position of sitting and lying, when back 2 is being near vertical state with seat portion 1, whole children's seat is the position of sitting state, when back 2 is being close parallel state with seat portion 1, whole children's seat is the position of lying state, when back 2 rotates to the position of lying state by the position of sitting state relatively seat portion 1, transmission assembly 4 makes leg fagging 3 follow the rotation and expand under the drive of back 2, children just can lie on children's seat this moment, the shank can be placed on leg fagging 3, when back 2 rotates to the position of sitting state relatively seat portion 1 by the position of lying state, transmission assembly 4 makes leg fagging 3 follow the rotation under the drive of back 2, children sit on seat portion 1, the shank is unsettled, the state conversion of children's seat only need rotate back 2 can, the simple operation.
When the backrest part 2 rotates backwards, the transmission component 4 drives the leg support plate 3 to rotate upwards relative to the seat part 1; when the backrest 2 rotates forwards, the transmission assembly 4 drives the leg rest 3 to rotate downwards relative to the seat 1.
When the backrest part 2 rotates backwards, the child seat rotates from a sitting position to a lying position, the transmission assembly 4 drives the leg supporting plates 3 to rotate upwards relative to the seat part 1, a child can put legs on the leg supporting plates 3, when the backrest part 2 rotates forwards, the child seat rotates from the lying position to the sitting position, the transmission assembly 4 drives the leg supporting plates 3 to rotate downwards relative to the seat part, the leg supporting plates 3 are located below the seat part 1, and the legs of the child are suspended when sitting.
