The seat assembly includes a seat 21 and a backrest 22. The front part of the seat 21 is pivotally connected to the upper part of the front bracket 11 or the lower part of the side bar 13, preferably the upper part of the front bracket 11, the lower part of the side bar 13 and the front part of the seat 21 are pivotally connected to each other coaxially, and the rear part of the seat 21 is pivotally connected to the second link 16. The backrest 22 is rotatably and slidably provided on the seat 21.

Specifically, the stroller further includes a slider 5, and the slider 5 is slidably provided on the seat 21 in the front-rear direction. The upper part of the rear bracket 12 is pivotally connected to the slider 5 by a first shaft 61, and the lower part of the backrest 22 is pivotally connected to the slider 5 by a second shaft 62.

In this embodiment, the first shaft 61 and the second shaft 62 extend in the left-right direction, and are disposed in parallel, and when the stroller is in the unfolded state, the second shaft 62 is located above the first shaft 61 and behind the first shaft 61, as shown in fig. 1 to 3.

Of course, the axes of the first shaft 61 and the second shaft 62 may extend in the same straight line direction, that is, the three components of the slider 5, the rear bracket 12, and the backrest 22 are pivotally connected coaxially.

In this embodiment, the seat 21 takes the form of a seat plate, and the left and right sides of the front portion of the seat plate 21 are pivotally connected coaxially with the upper portion of the front bracket 11 and the lower portion of the side bar 13, respectively, on the corresponding side, and the left and right sides of the rear portion of the seat plate 21 are pivotally connected with the second link 16, respectively, on the corresponding side.

The seat plate has a seating surface 211 contacting buttocks of the child, and the sliders 5 are slidably provided at left and right sides of the seat plate, respectively. The slider 5 of each side includes a body 51, a first connection portion 52, and a second connection portion 53. The body 51 is slidably provided on the seat plate in the front-rear direction, and is located below the seating surface 211. The first connecting portion 52 is located at the front end portion of the body 51 and extends downward of the body 51, and the upper portion of the rear bracket 12 is pivotally connected to the first connecting portion 52 by a first shaft 61. The second connecting portion 53 is located at the rear end portion of the body 51 and extends upward of the body 51, and the lower portion of the backrest 22 is pivotally connected to the second connecting portion 53 by a second shaft 62.

The seat plate 21 has slide grooves 212 extending in the front-rear direction on the left and right sides, the slide grooves 212 on the left and right sides are parallel to each other, and the second connecting portion 53 is provided so as to pass through the slide grooves 212 and slidably extend in the longitudinal direction of the slide grooves 212.

When the stroller is in the unfolded state, as shown in fig. 1 and 2, the left and right sliders 5 are both positioned at the rear end of the seat 21, and the second connecting portion 53 is positioned at the rear end of the chute 212 in the chute 212 so that the backrest 22 is far from the seat 21, which is supported at the rear of the seat 21, and the rear bracket 12 is far from the front bracket 11. On the front frame 11, the pivotal connection of the front frame 11, the side bars 13 and the seat 21 is located above the pivotal connection of the first link 15 with the front frame 11. On the rear bracket 12, the pivotal connection of the rear bracket 12 to the slider 5 is located above the pivotal connection of the second link 16 to the rear bracket 12. On the push rod assembly 14, the pivotal connection of the first link 15, the push rod assembly 14 and the second link 16 is located below the pivotal connection of the side bar 13 and the push rod assembly 14. On the second link 16, the pivotal connection of the first link 15, the push rod assembly 14 and the second link 16, the pivotal connection of the seat 21 and the second link 16, and the pivotal connection of the second link 16 and the rear bracket 12 are disposed in this order from the top down.

When the stroller is folded from the unfolded state, the sliding part 5 is lifted to slide forwards relative to the seat 21, the upper end part of the rear bracket 12 is driven to slide forwards and close to the front bracket 11, the backrest 22 moves forwards synchronously with the sliding part 5, in the process, the front bracket 11 and the side rods 13 rotate relative to the seat 21 around the pivot joint with the seat 21 and close to the seat 21, the push rod assembly 14 rotates forwards and downwards, the folding process is shown in fig. 4, and after the sliding part 5 slides forwards, the backrest 22 can rotate downwards under the action of self gravity and close to the seat 21, and finally the stroller is folded as shown in fig. 5.

The child stroller can be synchronously folded by linking the seat assembly when the stroller frame is folded, and the folding seat assembly does not need to be independently operated, so that the folding operation of the child stroller is convenient. Moreover, when the stroller is in the folded state, the backrest 22 is close to the seat 21 and is close to the stroller frame, so that the folded stroller is compact in structure, small in size and convenient to carry and store.

Example 2

As shown in fig. 6 to 10, in this embodiment, the backrest 22 is not pivotally connected to the slider 5, i.e., the slider 5 does not need to be provided with the second connecting portion 53. The backrest 22 is pivotally connected to the rear bracket 12 by a third shaft 63, the third shaft 63 being arranged parallel to the first shaft 61. The remainder was the same as in example 1.

When the stroller is in the unfolded state, on the rear bracket 12, the third shaft 63 is located below the first shaft 61 and behind the first shaft 61, and the third shaft 63 is located above the pivotal connection of the second link 16 and the rear bracket 12, as shown in fig. 6 to 8.

In this embodiment, when the stroller is folded from the unfolded state, as in embodiment 1, the sliding member 5 is slid forward relative to the seat 21, so that the upper end portion of the rear bracket 12 is slid forward to be close to the front bracket 11, and when the upper end portion of the rear bracket 12 is moved forward, the backrest 22 is driven to move forward synchronously, in the process, the front bracket 11 and the side bar 13 are both rotated relative to the seat 21 around the pivot connection with the seat 21 to be close to the seat 21, so that the push rod assembly 14 is rotated forward and downward, the folding process is as shown in fig. 9, and when the sliding member 5 is slid forward to be in place, the backrest 22 can be rotated downward to be close to the seat 21 under the action of self gravity, and finally the stroller is folded as shown in fig. 10.

The above embodiments are provided to illustrate the technical concept and features of the present invention and are intended to enable those skilled in the art to understand the content of the present invention and implement the same, and are not intended to limit the scope of the present invention. All equivalent changes or modifications made in accordance with the spirit of the present invention should be construed to be included in the scope of the present invention.
