[0045] See Figures 1 to 8 The present application provides a seat assembly 1000 for a child to ride on, and is typically mounted on a child carrier, such as a stroller. The seat assembly 1000 includes a seating portion 100 and a leg rest portion 200 that are arranged to rotate relative to each other along a front-to-back direction (the X direction in the figure). The leg rest portion 200 is located at the front of the seating portion 100. The seating portion 100 and the leg rest portion 200 are respectively used to support the child's buttocks and legs.

[0046] Among them, the rotation axis of the leg rest portion 200 extends in the left-right direction (Y direction in the figure), one of the seating portion 100 and the leg rest portion 200 is provided with a pivot 110 that can slide in the left-right direction, and the other is provided with an axis hole 211. The pivot 110 has a first position in which it extends into the axis hole 211 to realize the rotational connection between the seating portion 100 and the leg rest portion 200, and a second position in which the pivot 110 exits the axis hole 211 to realize the separation of the seating portion 100 and the leg rest portion 200.

[0047] In actual use, the user can remove the leg rest based on the passenger's leg length (e.g., if the legs are too short or too long) and the passenger does not need the leg rest, thereby reducing the weight of the child carrier and making it easier to carry. After removal, the leg rest can also be stacked with the seating portion for easier packaging and transportation. When the passenger needs the leg rest, the leg rest is installed and rotated as needed.

[0048] The figure shows one configuration of the seating portion 100. The seating portion 100 includes a frame-structured base 120 and a support plate (not shown). The base 120 includes connecting seats 121 and crossbars. There are two connecting seats 121, symmetrically arranged along the left and right sides. The crossbars are connected between the two connecting seats 121. There are at least two crossbars, including a front crossbar 122 and a rear crossbar 123. The pivot 110 is slidably mounted within the front crossbar 122. The support plate is made of a hard plate, a soft layer of material, or a combination of both.

[0049] In one embodiment, the seating portion 100 is provided with a slot 124, and the pivot 110 is slidably mounted within the seating portion 100. When in the first position, the pivot 110 extends into the corresponding slot 124. The legrest portion 200 is provided with a socket 212 that mates with the slot 124, and the shaft hole 211 is disposed on the socket 212. In conjunction with the foregoing, the slot 124 is disposed in the connecting seat 121, and the legrest portion 200 has a U-shaped structure. The sockets 212 are disposed at both ends of the U-shaped structure. When the sockets 212 and the slot 124 are engaged, they restrict the legrest portion 200 from rocking in the left-right direction relative to the seating portion 100. Accordingly, there are two pivots 110, symmetrically arranged along the left-right direction.

[0050] In one embodiment, the seat assembly 1000 further includes a first unlocking member 130 and a first elastic member 140. The first unlocking member 130 is movably mounted on the seating portion 100 and is in transmission engagement with the pivot 110. The first unlocking member 130 is used to drive the pivot 110 to switch to the second position, and the first elastic member 140 acts on the pivot 110 to return it to the first position. In conjunction with the specific structure of the seating portion 100 described above, there are two first unlocking members 130, symmetrically arranged along the left-right direction. The first unlocking members 130 are slidably mounted on the front crossbar 122 and fixedly connected to the corresponding pivot 110 therein via a latch. The front crossbar 122 is provided with a slot that engages with the latch. The first elastic member 140 is a spring, disposed between the two pivots 110, with its two ends acting on the ends of the two pivots 110, respectively.

[0051] The actual operation is: when the leg support 200 is disassembled, Figure 6 As shown, two fingers of one hand press the two first unlocking members 130 to bring them closer to each other, driving the pivot 110 to switch to the second position, and the other hand disassembles the leg support 200 from the slot 124, releasing the first unlocking member 130, and the first elastic member 140 is reset to restore the pivot 110 to the first position.

[0052] In one embodiment, the seating portion 100 is provided with a positioning portion for limiting the rotation range of the leg rest portion 200, wherein the seating portion 100 has a horizontal top surface, and the leg rest portion 200 has a substantially horizontal first posture (eg, Figure 1 ), and a second posture tilted relative to the horizontal state (such as Figure 3 ), the second posture can be one or more, and the multiple postures are reflected in different tilt angles. The figure only shows one of the second postures. The positioning part includes:

[0053] The first positioning portion 151, such as Figure 9 When the seating portion 100 switches to the first posture, the first positioning portion 151 abuts against the leg rest portion 200 to bring it to the first posture;

[0054] The second positioning portion 152, such as Figure 10 When the seating portion 100 switches to the second posture, the second positioning portion 152 abuts against the leg rest portion 200 to bring it to the second posture.

[0055] See also Figure 1 、 Figure 2 、 Figure 11 and Figure 12 In another embodiment, a locking mechanism is provided between the leg rest portion 200 and the seating portion 100 to keep the leg rest portion 200 in the first posture. The locking mechanism includes:

[0056] A locking slot 125 is provided on the front crossbar 122;

[0057] The locking member 220 is slidably mounted on the U-shaped structure and has a locked state where it extends into the locking slot 125 , and a released state where it exits the locking slot 125 .

[0058] In combination with the above embodiment, when there are multiple second postures, the locking slots 125 are correspondingly provided in multiple numbers and are arranged around the pivot on the front crossbar 122. That is, the locking mechanism can also keep the leg rest portion 200 in the second posture.

[0059] Among them, the leg rest portion 200 includes a U-shaped rod 231 (that is, the aforementioned U-shaped structure), and a slide 232 slidably installed on both sides of the U-shaped rod 231, and a roughly U-shaped rod structure 233 is fixedly connected between the two slides. The two ends of the rod structure 233 extend out of the slide 232 as a locking member 220, and a handle 234 for easy gripping is provided in the middle of the rod structure 233.

[0060] See also Figure 13 The present application also provides a child carrier 5000, comprising two opposing side frames 500 and a seat assembly 1000 mounted between the side frames 500. The structure of the seat assembly 1000 is similar to that of the previous embodiment. As shown, the side frames 500 include a front leg assembly 510, a rear leg assembly 520, and a push handle assembly 530.

[0061] The seat assembly 1000 also includes a flexible cloth cover 160 (the bold dashed portion in the figure), which is connected between the seating portion 100 and the two side frames 500 (for example, connected to the push handle assembly 530) to form a seat backrest 300, which is used to support the child's back.

[0062] The seat assembly of the present application has a detachable connection between the legrest and the seating portion. Specifically, when the legrest is mounted on the seating portion, it can be rotated relative to the seating portion to meet different usage requirements. When the legrest is not in use by the passenger, the legrest can be removed to reduce the weight of the seat assembly. Furthermore, the detachable legrest facilitates packaging and transportation.

[0063] The technical features of the above embodiments may be combined in any manner. To simplify the description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there are no conflicts in the combination of these technical features, they should be considered to be within the scope of this specification. When technical features in different embodiments are reflected in the same figure, it can be regarded as that figure also discloses the combination examples of the various embodiments involved.

[0064] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art could make numerous variations and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application.
