Detailed Description

The following detailed description of the preferred embodiments of the invention, taken in conjunction with the accompanying drawings, enables those skilled in the art to more readily understand the advantages and features of the invention.

The terms "front", "rear", "left", "right", "inner", "outer" and the like in the following embodiments are defined according to the normal use habit of the seat pocket, when the seat pocket is opened, a child is seated in the seat pocket, the child faces in the direction of "front" and faces back in the direction of "rear", the left and right sides of the child are respectively "left" and "right", the direction of "inner" and vice versa is toward the center of the seat pocket.

Referring to fig. 1 to 10, the child seat pocket of the embodiment includes a seat plate 1, a backrest 2, and armrests 3, which are rotatably connected by a rotating shaft 4, and the backrest 2 and the armrests 3 can be unfolded and folded with respect to the seat plate 1 by rotating themselves.

The child seat pocket further comprises a locking mechanism capable of locking both the armrest 3 and the backrest 2 in the unfolded position relative to the seat plate 1. It should be noted that the lock mechanism has two locking pieces for locking the position of the backrest 2 and the position of the armrest 3, respectively. Since the locking structure of the backrest 2 is not the focus of the present invention, and thus will not be described in detail, the locking member 5 mentioned hereinafter refers to a locking member for locking the position of the armrest 3.

The locking mechanism comprises a locking hole 32 arranged on the armrest 3, the locking piece 5 is movably arranged between the seat board 1 and the armrest 3 and is detachably inserted with the locking hole 32, and when the locking piece 5 is inserted with the locking hole 32, the position of the armrest 3 is locked. At least one of the locking member 5 and the backrest 2 has a slope, and during the rotation of the backrest 2 from its unfolded position relative to the seat plate 1 toward the seat plate 1, the backrest 2 and the locking member 5 are brought into sliding contact by the slope to move the locking member 5 away from the armrest 3 and out of the locking hole 32. In this embodiment, the moving direction of the locking member 5 is parallel to the rotation shaft 4.

In this embodiment, the specific structure of the inclined plane is as follows: the locking member 5 is provided with a first inclined surface 51, the backrest 2 is provided with a second inclined surface 22, and during the process that the backrest 2 rotates towards the seat plate 1 from the unfolded position relative to the seat plate 1, the second inclined surface 22 is in sliding contact with the first inclined surface 51 so as to push the locking member 5 to move. More specifically, the backrest 2 is provided with a convex rib 23, the second inclined surface 22 is provided on the rib 23, and the rib 23 is arc-shaped and has a center on the axis of the rotating shaft 4.

In a more preferred embodiment, the seat board 1, the backrest 2 and the armrests 3 rotate with each other in the following specific structure: the seat plate 1 is provided with a seat plate connecting part 11 extending upwards, the backrest 2 is provided with a backrest connecting part 21 extending forwards, the end part of the armrest 3 is provided with an armrest connecting part 31, the seat plate connecting part 11, the backrest connecting part 21 and the armrest connecting part 31 are rotatably connected through a rotating shaft 4, and the seat plate connecting part 11, the backrest connecting part 21 and the armrest connecting part 31 are sequentially arranged from outside to inside. More specifically, there are two seat plate connecting portions 11, two backrest connecting portions 21, and two armrest connecting portions 31 respectively disposed at the left and right sides of the child seat pocket, the seat plate connecting portion 11, the backrest connecting portion 21, and the armrest connecting portion 31 located at the same side are rotatably connected by a rotating shaft 4, and the axial lines of the rotating shafts 4 at the left and right sides coincide with each other. The two groups of locking mechanisms are also symmetrically arranged at the left side and the right side of the child seat pocket.

Preferably, the second inclined surface 22 is provided on a side of the back connection portion 21 facing the seat plate connection portion 11.

Since the backrest connecting portion 21 in this embodiment is disposed between the seat plate connecting portion 11 and the armrest connecting portion 31, the backrest connecting portion 21 is provided with an avoiding groove 24 for the locking member 5 to pass through to connect with the locking hole 32. The avoiding groove 24 is arc-shaped, and the center of the arc is on the axis of the rotating shaft 4.

In this embodiment, after the armrest 3 is unlocked, the armrest 3 can rotate toward the seat plate 1 under the action of gravity to be close to the seat plate 1. In another embodiment, when the armrest 3 and the backrest 2 are both in the unfolded position relative to the seat plate 1, the armrest 3 is located in front of the backrest 2, so that after the armrest 3 is unlocked, and after the backrest 2 is rotated to the armrest 3 and against the armrest 3, the backrest 2 is further rotated forward and downward, which pushes the armrest 3 together to rotate closer to the seat plate 1.

The seat plate 1 is further provided with an elastic member 6 for inserting the locking member 5 into the locking hole 32, and during the unfolding of the armrest 3, when the armrest 3 is rotated to the corresponding position, the locking member 5 is pushed by the elastic member 6 to be inserted into the locking hole 32.

The folding working principle of the seat pocket for children is as follows:

in folding the child seat pocket, the backrest 2 is first unlocked by an operation and then the backrest 2 is rotated forward and downward to be close to the seat plate 1. During the rotation of the backrest 2, the locking member 5 is driven to move by the sliding contact of the second inclined surface 22 and the first inclined surface 51, the locking member 5 is disengaged from the locking hole 32 of the armrest 3, so that the armrest 3 is unlocked, and the armrest 3 rotates closer to the seat plate 1 along with the backrest 2. When the backrest 2 and the armrests 3 are close to the seat board 1, the seat bag for children is folded.

The children's seat pocket in above-mentioned embodiment when folding, can drive the locking piece and remove and make the handrail unblock when rotating the back, behind the handrail unblock, follows the back and rotates and accomplish the folding whole process of children's seat pocket together. This children's seat pocket has simplified folding operation step to simple structure, manufacturing cost is lower.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
