[0065] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. It is understood that, without conflict, some technical means of the various embodiments described herein can be substituted for or combined with each other.

[0066] In the description of this utility model specification and claims, the terms "first," "second," etc., are used only to distinguish the described objects and do not have any sequential or technical meaning.

Furthermore, the words "a" or "one," etc., do not indicate a quantity limitation, but rather indicate the presence of at least one, while "multiple" indicates at least two.

[0067] In the description of this utility model and its claims, terms such as "connect," "install," "fix," and "retain" should be interpreted broadly unless otherwise specified. For example, "connect" can mean a separate connection or an integral connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean a non-detachable connection or a detachable connection. As another example, "retain" does not necessarily mean complete containment; this concept also includes the containment of parts that protrude externally. Those skilled in the art can understand the specific meaning of the aforementioned terms in this utility model according to the specific circumstances.

[0068] In the description of this utility model and its claims, the terms "upper," "lower," "horizontal," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the drawings, are only for the purpose of clearly and simply describing this utility model, and do not indicate or imply that the elements referred to must have a specific orientation or be constructed and operated in a specific orientation. These directional terms are relative concepts used for relative description and clarification, and can change accordingly depending on the orientation of the components in the drawings. For example, if the device in the drawings is flipped, an element described as "below" other elements will be positioned "above" other elements.

[0069] In the description of this utility model specification and claims, the term "if" is generally interchangeable with "when," "at," "in response to determination," or "in response to detection," depending on the context.

[0070] In the description of this utility model specification and claims, if there is a "direction" of motion, including motion with a directional component, the term "in direction" is not necessarily understood as motion only in that one direction. Those skilled in the art can understand the specific meaning of the aforementioned terms in this utility model according to the specific circumstances.

[0071] This utility model discloses a seat saddle installed on the frame of a baby stroller, including a seat saddle frame and a seat saddle cover fitted over the seat saddle frame. The seat saddle frame includes a seat cushion assembly and a support assembly, wherein the support assembly includes a backrest panel and a support rod, the backrest panel is connected to the seat cushion assembly and can rotate relative to it, and the support rod is fixed relative to the seat saddle cover.

[0072] The support rod is movably connected to the push handle assembly of the frame via a side rod. When the side rod and the push handle assembly are locked, the seat is mounted on the frame in the opposite direction via the side rod. When the side rod and the push handle assembly are unlocked, the seat is moved closer to the push handle assembly via the side rod and folds in.

[0073] Here, the seat is mounted backwards on the frame. The distinction is made by whether the direction the seat opening faces is the same as the direction the stroller is being pushed: when both are facing the same direction, see [link to relevant documentation]. Figure 1 The seat is mounted facing forward on the frame (in this case, the infant or child is usually facing the direction of travel); when the two are reversed, see [reference needed]. Figure 7 and Figure 8 The seat 10 is mounted backwards on the frame 3 (at which point the infant or child is usually facing away from the direction of travel).

[0074] The side bar 130 of this utility model not only provides reverse mounting of the seat 10 to the frame 3, but also provides support and side protection for the seat 10.

[0075] Here, the side bar, as the connecting component between the strut and the push handle assembly of the frame, can be implemented in various ways.

[0076] According to one example of this utility model, the side rod can be a folding rod, comprising at least two sub-rods capable of folding together. (See also...) Figures 16 to 20 According to a specific example of this utility model, one end of the side rod 130 is rotatably connected to the support rod 121, and the other end is rotatably connected to the push rod 310; the side rod 130 includes sub-rods 131 and 132, and a folding joint 133 is provided between the sub-rods 131 and 132. When the seat 10 is in the unfolded state, the sub-rods 131 and 132 are locked by the folding joint 133, the side rod 130 is straightened, and the seat 10 unfolds in a direction away from the push handle assembly 30. When the seat 10 is in the folded state, the sub-rods 131 and 132 fold together with each other by the folding joint 133, and the seat 10 moves closer to the push handle assembly 30.

[0077] According to one example of this utility model, the side rod can be a telescopic rod, comprising two or more rod segments, wherein at least two rod segments are capable of sliding and telescopically extending relative to each other. (See also...) Figures 21 to 25 According to a specific example of this utility model, one end of the side rod 130 is rotatably connected to the support rod 121, and the other end is rotatably connected to the push rod 310; the side rod 130 includes two rod segments 135 and 136 that can slide and extend relative to each other. When the seat 10 needs to be unfolded, the rod segments 135 and 136 move in opposite directions to stretch the side rod 130, thereby opening the seat 10 away from the push handle assembly 30. When the seat 10 needs to be retracted, the rod segments 135 and 136 move towards each other to retract the side rod 130, thereby bringing the seat 10 closer to the push handle assembly 30.

[0078] According to one example of this invention, a side bar can be detachably connected to the push handle assembly. One end of the side bar is rotatably connected to a strut, and the other end is connected to the push handle assembly via a detachable connector. When the seat needs to be extended, the side bar is connected to the push handle assembly via this connector, thereby providing support and connection to the seat, allowing the seat to open away from the push handle assembly. When the seat needs to be retracted, the connector is detached from the push handle assembly, and the seat will close towards the push handle assembly without the support provided by the side bar. As the seat's support assembly closes to the frame's push handle assembly, the side bar rotates about its connection point with the strut until it is approximately parallel to the strut.

[0079] According to one example of this invention, the side rod can be connected to the push handle assembly via a sliding connector at its end. (See also...) Figures 7 to 15According to a specific example of this utility model, one end of the side rod 130 is rotatably connected to the support rod 121, and the other end is connected to the push rod 310 via a sliding connector 140. When the sliding connector 140 is locked to the push rod 310, the side rod 130 supports the seat 10 away from the push handle assembly 30 and enters the unfolded state; when the locking of the sliding connector 140 and the push rod 310 is released, the sliding connector 140 can slide along the push rod 310, thereby the seat 10 moves closer to the push handle assembly 30 via the side rod 130.

[0080] Here, the frame structures suitable for a reverse-facing seat include two-fold and three-fold bicycles. See also Figures 26 to 31 The frame 4 shown is a folding bicycle, with a side bar 130 movably connected between the support rod 121 and the push handle assembly 30 of the frame 4, allowing the seat 10 to be opened or closed relative to the frame 4. (See also...) Figure 7 The frame 3 shown is a three-fold bicycle, with a side bar movably connected between the support rod 121 and the push rod 310 of the push handle assembly 30, so that the seat 10 can be opened or closed relative to the frame 3.

[0081] Here, the push handle assembly includes a one-piece push handle, a telescopic push handle, or a folding push handle consisting of two or more sets of rods rotatably connected to each other. See also Figure 26 The push handle assembly 30 is a one-piece push handle. (See also...) Figure 7 and Figure 8 The push handle assembly 30 is a folding push handle, and the push handle 320 and the push rod 310 have a folding joint.

[0082] See also Figures 2 to 12 The illustration shows a seat and a stroller having the seat according to one embodiment of the present invention.

[0083] The seat 10 includes a seat frame 1 and a seat cover 2 fitted over the seat frame 1. The seat frame 1 includes a seat cushion assembly 110 and a support assembly 120. The support assembly 120 further includes a backrest 122 and a support rod 121. The backrest 122 is connected to the seat cushion assembly 110 and can rotate relative to it. The support rod 121 is fixed relative to the seat cover 2.

[0084] A side rod 130 is movably connected between the support rod 121 and the push handle assembly 30 of the frame 3. When the side rod 130 and the push handle assembly 30 are locked, the seat 10 is mounted on the frame 3 in the opposite direction via the side rod 130. When the side rod 130 and the push handle assembly 30 are unlocked, the seat 10 moves closer to the push handle assembly 30 via the side rod 130 and retracts.

[0085] One end of the side rod 130 is rotatably connected to the support rod 121, and the other end is connected to the push handle assembly 30 of the frame 3 via a sliding connector 140. The sliding connector 140 can at least partially expose the seat cover 2, rather than being completely covered by the seat cover 2, thereby facilitating installation and removal.

[0086] See Figure 4 , 7 In example 8, the end of the side rod 130 does not extend beyond the support rod 121, and the connection between the side rod 130 and the support rod 121 is inverted V-shape, allowing the side rod 130 to rotate relative to the support rod 121. In other examples not shown in the figures, the connection between the side rod 130 and the support rod 121 can also be in a positive V-shape, i.e., the connection point is closer to the seat cushion assembly 110, and the connection point between the sliding connector 140 and the push rod 310 is higher than the connection point between the side rod 130 and the support rod 121.

[0087] A sliding connector 140 is movably connected between the side rod 130 and the push handle assembly 30. When the side rod 130 and the push handle assembly 30 are in the unlocked state, the side rod 130 is slidably connected to the push handle assembly 30 via the sliding connector 140. In some examples, the push handle assembly includes a push rod 310 and a push handle 320, and the side rod 130 can be connected to the push rod 310 via the sliding connector 140.

[0088] The sliding connector 140 performs two structural functions on the push rod 310: 1) it limits the side rod 130 by locking it with the push rod 310; 2) after unlocking it from the push rod 310, it can drive the side rod 130 to slide along the push rod 310.

[0089] This can be achieved using a variety of structures.

[0090] In an example not shown in the figure, a typical structure is that the sliding connector 140 includes a sliding structure and a locking structure. The sliding structure can be, for example, a sleeve that sleeves the sliding connector 140 over the push rod 310 and allows it to slide along the push rod 310. The locking structure is used to lock the sliding connector 140 to a specific position on the push rod 310. For example, a buckle can be used to fasten the sleeve to the push rod 310 to limit the side rod 130.

[0091] In another example, see reference. Figures 7 to 9 The side rod 130 can be connected to the push rod 310 via a sliding connector 140. The push rod 310 is provided with a sliding locking member 312 corresponding to the sliding connector 140. The sliding connector 140 is rotatably connected to the end of the side rod 130 and locked to the fixed position of the push rod 310 by the sliding locking member 312. When the lock with the sliding locking member 312 is released, the sliding connector 140 can slide along the push rod 310.

[0092] At this time, the sliding connector 140, in conjunction with the sliding locking member 312, achieves the limiting and sliding functions on the push rod 310: 1) The sliding locking member 312 arranged on the push rod 310 limits and locks the sliding connector 140, thereby also limiting and locking the side rod 130; 2) After the sliding connector 140 and the sliding locking member 312 are unlocked, the sliding connector 140 can slide along the push rod 310, thereby driving the side rod 130 to slide along the push rod 310.

[0093] The sliding connector 140 and the sliding locking member 312 have corresponding snap-fit ​​structures to lock the sliding connector 140, and after the snap-fit ​​structure releases the lock on the sliding connector 140, the sliding connector 140 can slide along the push rod 310. (See also...) Figures 7 to 9 In a specific example, the sliding connector 140 can be a sliding buckle, and the sliding locking member 312 is a limiting structure, such as a pair of limiting protrusions. The sliding buckle locks the sliding connector 140 by engaging with the limiting protrusions. When the sliding buckle is released from the limiting protrusions, it can slide along the push rod 310. Alternatively, the sliding locking member 312 can also use other structures to limit the sliding connector 140, such as limiting grooves, limiting holes, or limiting protrusions.

[0094] Furthermore, in an example not shown in the illustration, the sliding connector 140 can also be a composite structure, including a slider structure and a locking structure. The slider structure allows the sliding connector 140 to slide along the push rod 310, and the locking structure cooperates with the sliding locking member 312 to lock the sliding connector 140 to a specific position on the push rod 310. The locking structure and the sliding locking member 312 are corresponding structures, such as a locking pin and a limiting slot / hole for receiving the locking pin, so that the two lock the sliding connector 140 by a pin connection.

[0095] This invention does not limit the specific structure of the sliding connector 140 and the sliding locking member 312, and any specific structure that can realize the above-mentioned structural functions of the sliding connector 140 is referenced and included herein.

[0096] In some examples, the seat assembly 110 is movably connected to the frame 3 via a connector.

[0097] See Figures 2 to 8 The seat 10 is mounted backwards on the stroller frame 3. The seat 10 can be quickly mounted to or removed from the frame 3 via the connector of the seat assembly 110 and the sliding connector 140 of the side bar 130.

[0098] The frame 3 is a three-fold frame, including a push handle assembly, a front support assembly, and a rear support assembly. The push handle assembly 30 includes a push rod 310 and a push handle 320, the front support assembly includes a front support 330 and a front wheel, and the rear support assembly includes a rear support 340 and a rear wheel.

[0099] The upper end of the push rod 310 is rotatably connected to the push handle 320, and the lower end of the push rod 310 is rotatably connected to the front bracket 330 and the rear bracket 340. The front end of the connecting rod 360 is rotatably connected to the front bracket 330, and the rear end of the connecting rod 360 is rotatably connected to the lower end of the rear support rod 350. The upper end of the rear support rod 350 is rotatably connected to the push handle assembly 30, and the lower part of the rear support rod 350 is rotatably connected to the rear bracket 340.

[0100] See Figure 6 The upper part of the frame 3 serves as the push part, including the push handle assembly 30, and the lower part serves as the support part, including the front support assembly and the rear support assembly. The push rod 310 is rotatably connected to the front support 330 and the rear support 340, and the connecting part serves as the seat support part for placing the seat 10.

[0101] The seat cushion assembly 110 can be movably connected to the seat support via a connector.

[0102] In a specific example, the intersection of the push rod 310 with the front support 330 and the rear support 340 on both sides of the frame 3 is the seat support portion, which is supported by a first crossbar 311 connecting the intersection of the two sides. The seat cushion assembly 110 can be movably or fixedly connected to the first crossbar 311 by a connector, such as a buckle.

[0103] Furthermore, the connecting parts of the seat cushion assembly 110 may also include a first connecting part and a second connecting part, which are connected to the seat support portion of the frame 3 in a non-collinear manner. For example, the first connecting part and the second connecting part are respectively connected to the front and rear sides of the seat support portion of the frame 3, thereby ensuring that the seat 10 is securely connected to the frame 3 and will not tip over.

[0104] Continue reading Figure 6 The frame 3 is reinforced with a rear strut 350 between the upper and lower parts on both sides, which also improves the stability of the frame structure. This is very effective in an inverted Y-shaped frame. Therefore, the rear strut serves as an intermediate support structure, providing support between the push handle assembly 30 and the rear support 340, and is rotatably connected to both.

[0105] See Figure 8In one specific example, the upper end of the rear support rod 350 is rotatably connected to the push handle assembly 30, the middle of the rear support rod 350 is rotatably connected to the rear support 340, and the lower end of the rear support rod 350 is rotatably connected to the end of the connecting rod 360 near the rear support 340. A second crossbar 351 is provided between the rear support rods 350 on both sides of the frame 3. The seat cushion assembly 110 can be connected to the first crossbar 311 on the front side of the seat support portion via a first connector, and to the second crossbar 351 on the rear side of the seat support portion via a second connector.

[0106] The seat cushion assembly 110 includes a seat plate, which can be fitted with a removable cushion for better comfort, or feature an ergonomically curved seat plate to alleviate fatigue during long journeys. A first connector and a second connector can be located at the bottom of the seat plate. The first connector can be, for example, a snap fastener 111, which achieves a fixed or rotatable connection to the first crossbar 311 by fastening at both ends. The second connector can be, for example, a retaining strap 112, at least one end of which can be detachably connected to the bottom of the seat cushion assembly 110. The retaining strap 112 is fitted onto the second crossbar 351 and can rotate relative to the second crossbar 351, thereby preventing the seat cushion assembly 110 from flipping upwards.

[0107] In some examples, the seat cover 2 is provided with a connecting part, and the support rod 121 is connected to the connecting part, thereby fixing it relative to the seat cover.

[0108] The connecting part can have various specific structures. For example, it can be a channel through which the support rod 121 can pass, arranged on the top or sides of the seat cover 2. Alternatively, the connecting part can be a buckle arranged on the top or sides of the seat cover 2 for fixing the support rod 121. This utility model does not limit the specific structure of the connecting part; any structure that can fix the support rod 121 to the seat cover 2 can be used here and is included within the protection scope of this utility model.

[0109] See Figure 4 and Figure 5 In a specific example, the support rod 121 is a U-shaped rod, and the connecting part of the seat cover 2 is a channel 21 arranged on both sides of the seat cover 2. The two sides of the support rod 121 pass through the channel 21 to fix and connect with the seat cover 2, and at the same time, it can also provide lateral support for the seat cover 2.

[0110] The support rod 121 is located between the backrest panel 122 and the canopy rod 150, and together with the backrest panel 122 and the canopy rod 150, it supports the seat cover 2, thereby forming the internal space of the seat cover 10.

[0111] The seat cover 2 has a folding part. When the folding part is folded up, the seat 10 is in a sitting position. When the folding part is unfolded, the seat 10 is in a lying position.

[0112] When folded up, the folded portion of the seat cover 2 can be positioned behind the support rod 121. This rear area can be broadly interpreted as follows: depending on the orientation of the seat 10, with the opening of the seat 10 as the front, the canopy rod 150, the support rod 121, and the backrest panel 122 sequentially move backward. Therefore, the rear area of ​​the support rod 121 includes the area between the support rod 121 and the backrest panel 122, as well as the rear area of ​​the backrest panel 122. For example, when folded up, the folded portion of the seat cover 2 can be positioned between the support rod 121 and the backrest panel 122, or behind the backrest panel 122 (i.e., the back area of ​​the backrest panel 122).

[0113] The folded portion of the seat cover 2 can be folded up using a locking mechanism. This locking mechanism is typically a zipper assembly, but can also be a strap, buckle, Velcro, magnetic assembly, etc. This utility model does not specifically limit the specific type of locking mechanism, and any locking mechanism that can be used for the folded portion of the seat cover 2 is incorporated herein by reference.

[0114] For example, the locking structure uses a zipper assembly located on the rear outer periphery of the backrest panel 122. When the zipper assembly is closed, the folded portion of the seat cover 2 is folded up, at which point the backrest panel 122 and the seat cushion assembly 110 are at an angle, and the seat cover 10 is in a sitting position. When the zipper assembly is opened, the folded portion of the seat cover 2 is opened, at which point the backrest panel 122 flips backward relative to the seat cushion assembly 110, and the two are at a reclining angle, and the seat cover 10 is in a reclining position. Due to the separate design of the backrest panel 122 and the support rod 121, the backrest panel 122 can flip backward to a larger angle, for example, up to 150°, thus the seat cover 10 of this invention can provide a larger reclining space 210.

[0115] See also Figure 4 and Figure 5 ,like Figure 4 As shown, when the folded portion of the seat cover 2 is folded up, the seat cover 2 surrounds the seat cushion assembly 110, the backrest 122, the support rod 121, and the canopy rod 150, forming a seating space within the seat cover 10; then refer to Figure 5 When the folding part of the seat cover 2 is opened, the backrest 122 flips back away from the support rod 121 to a reclining angle. The seat cover 2 is also provided with a strap 22 to limit the backrest 122. The folding part provides a reclining space 210 between the backrest 122 and the support rod 121, so that the seat 10 changes from a sitting position to a reclining position.

[0116] In some examples not shown in the illustrations, the backrest 122 and the seat cushion assembly 110 are designed separately. The connection between the backrest 122 and the seat cushion assembly 110 can be achieved via the seat cover 2, and the backrest 122 and the seat cushion assembly 110 can rotate relative to each other when switching between a sitting angle and a reclining angle. The backrest 122 and the seat cushion assembly 110 can be respectively fitted into specific positions within the seat cover 2. When the folded portion of the seat cover 2 is folded up, the connection position between the backrest 122 and the seat cushion assembly 110 is at a sitting angle; when the folded portion of the seat cover 2 is unfolded, the backrest 122 flips backward relative to the seat cushion assembly 110, and the connection position with the seat cushion assembly 110 changes to a reclining angle. In this example, the folded portion of the seat cover 2 can be placed in front of the backrest 122 when folded up, such as in the area between the support rod 121 and the backrest 122, so that the backrest 122 fixed inside the seat cover 2 can be flipped back to a reclining angle as the folded portion is opened.

[0117] See Figures 7 to 12 When the side rod 130 and the push handle assembly 30 are in the locked state, that is, the sliding locking member 312 locks the sliding connector 140, so that the sliding connector 140 together with the side rod 130 is kept in the locked position of the push rod 310 and cannot slide relative to the push rod 310; the side rod 130 tightens the support rod 121 and, together with the seat cushion assembly 110 and the support assembly 120, supports the seat cover 2. The seat 10 is mounted in reverse on the frame 3.

[0118] When folding the stroller, it is necessary to unlock the frame and release the locking state of the side bar 130 and the push handle assembly 30. This utility model does not limit the unlocking order of the two; different unlocking orders are possible under different folding methods.

[0119] The push handle 320 has a frame folding handle, which is used to unlock the frame and fold it.

[0120] When folding the stroller, the sliding locking piece 312 on the push rod 310 must be released from its lock on the sliding connecting piece 140 on the side rod 130. The sliding connecting piece 140 slides downward along the push rod 310, and the support assembly 120 moves closer to the push rod 310 to retract. The frame 3 also folds simultaneously. The push rod 310 is subjected to a downward force, which causes the support assembly 120 and the seat cushion assembly 110 to retract towards the rear support 340, and the front support 330 also retracts towards the rear support 340, thus completing the folding and retraction of the stroller.

[0121] Depending on the position of the rotational connection point of the side rod 130 on the support rod 121, if the connection point is closer to the seat cushion direction, the sliding connector 140 will slide upward along the push rod 310 after unlocking, and at the same time the support component 120 will move closer to the push rod 310 via the side rod 130.

[0122] After folding, refer to Figure 10 and Figure 11 The push rod 310 and push handle 320 are folded and tucked behind the rear support 340, the front support 330 is tucked in front of the rear support 340, and the support assembly 120 and seat assembly 110 are folded and tucked in with the frame 3 and tucked between the push rod 310 and push handle 320.

[0123] The folding of the frame can be achieved in the following two ways:

[0124] Folding method 1:

[0125] See Figure 9 First, the sliding locking piece 312 is released from locking the sliding connecting piece 140, causing the backrest panel 122 and support rod 121 to retract towards the push rod 310. During the retraction process, the sliding connecting piece 140 slides downward along the push rod 310 under the action of the side rod 130 until the support assembly 120 approaches the push rod 310. Then, the frame 3 is unlocked by squeezing the handle on the push handle 320, which rotates forward. By applying a downward force to the push rod 310, the push rod 310 causes the support assembly 120 and the seat cushion assembly 110 to retract towards the rear support 340. Under the linkage of the rear support rod 350 and the connecting rod 360, the front support 330 also retracts towards the rear support 340, thus completing the folding and retraction of the trolley. See the image for the folded and retracted state of the trolley. Figure 10 and Figure 11 .

[0126] Folding method 2:

[0127] First, unlock frame 3 and sliding connector 140, then turn push handle 320 forward to begin folding the frame. See below. Figure 12 During the folding process, push rod 310 and rear support rod 350 rotate downwards, causing support assembly 120 to tilt backwards (towards the frame). When the tilt reaches a certain degree, the weight of support assembly 120 acts on side rod 130, causing sliding connector 140 to slide downwards along push rod 310, further driving support assembly 120 to fold towards push rod 310. Push rod 310 continues to rotate downwards, driving support assembly 120 and seat cushion assembly 110 to fold towards rear support 340. Under the combined action of rear support rod 350 and connecting rod 360, front support 330 also folds towards rear support 340, thus completing the folding of the trolley. See the image for the folded state of the trolley. Figure 10 and Figure 11 .

[0128] See also Figures 13 to 15 The illustration shows a seat and a stroller having the seat according to one embodiment of the present invention.

[0129] The seat 10 includes a seat frame 1 and a seat cover 2 fitted over the seat frame 1. The seat frame 1 includes a seat cushion assembly 110 and a support assembly 120. The support assembly 120 further includes a backrest 122 and a support rod 121. The backrest 122 is connected to the seat cushion assembly 110 and can rotate relative to it. The support rod 121 is fixed relative to the seat cover 2.

[0130] A side rod 130 is movably connected between the support rod 121 and the push handle assembly 30 of the frame 3. When the side rod 130 and the push handle assembly 30 are locked, the seat 10 is mounted on the frame 3 in the opposite direction via the side rod 130. When the side rod 130 and the push handle assembly 30 are unlocked, the seat 10 moves closer to the push handle assembly 30 via the side rod 130 and retracts.

[0131] One end of the side rod 130 is rotatably connected to the support rod 121 at a non-end position, while the other end is connected to the push handle assembly 30 via a sliding connector 140. The end of the side rod 130 extends beyond the support rod 121, and the side rod 130 and the support rod 121 are connected in an X-shape at their connection point, allowing the side rod 130 to rotate relative to the support rod 121.

[0132] A sliding connector 140 is movably connected between the side rod 130 and the push handle assembly 30. When the side rod 130 and the push handle assembly 30 are in the unlocked state, the side rod 130 is slidably connected to the push handle assembly 30 via the sliding connector 140. In some examples, the push handle assembly 30 includes a push rod 310 and a push handle 320, and the side rod 130 can be connected to the push rod 310 via the sliding connector 140.

[0133] In some examples, the seat assembly 110 is movably connected to the frame 3 via a connector. The frame 3 is a three-fold frame, including a handlebar assembly, a front support assembly, and a rear support assembly, wherein the front support assembly includes a front support 330 and a front wheel, and the rear support assembly includes a rear support 340 and a rear wheel.

[0134] In some examples, the support rod 121 is a U-shaped rod that is threaded through the channels 21 on both sides of the seat cover 2, thereby fixing it relative to the seat cover 2. The support rod 121, together with the backrest plate 122, supports the seat cover 2, thereby forming the internal space of the seat cover 20.

[0135] See also Figures 16 to 20 The illustration shows a seat and a stroller having the seat according to one embodiment of the present invention.

[0136] The frame 3 is a three-fold frame, including a push handle assembly, a front support assembly, and a rear support assembly. The push handle assembly 30 includes a push rod 310 and a push handle 320, the front support assembly includes a front support 330 and a front wheel, and the rear support assembly includes a rear support 340 and a rear wheel.

[0137] The seat 10 includes a seat frame 1 and a seat cover 2 fitted over the seat frame 1. The seat frame 1 includes a seat cushion assembly 110 and a support assembly 120. The support assembly 120 further includes a backrest 122 and a support rod 121. The backrest 122 is connected to the seat cushion assembly 110 and can rotate relative to it. The support rod 121 is fixed relative to the seat cover 2.

[0138] A side rod 130 is movably connected between the support rod 121 and the push handle assembly 30 of the frame 3. When the side rod 130 and the push handle assembly 30 are locked, the seat 10 is mounted on the frame 3 in the opposite direction via the side rod 130. When the side rod 130 and the push handle assembly 30 are unlocked, the seat 10 moves closer to the push handle assembly 30 via the side rod 130 and retracts.

[0139] One end of the side rod 130 is rotatably connected to the support rod 121, and the other end is rotatably connected to the push rod 310 of the push handle assembly 30 via a connecting block 134. The connecting block 134 can at least partially expose the seat cover 2, rather than being completely covered by the seat cover 2, thereby facilitating installation and removal.

[0140] The side bar 130 includes sub-bars 131 and 132, with a folding joint 133 between them. When the folding joint 133 locks the sub-bars 131 and 132, the side bar 130 supports the seat 10 to unfold relative to the frame 3; when the sub-bars 131 and 132 fold together with each other via the folding joint 133, the seat 10 retracts relative to the frame 3.

[0141] The intersection of the push handle assembly, front support assembly, and rear support assembly on both sides of the frame 3 forms the seat support area, which is supported by a first crossbar 311 connecting the intersection of the two sides. A rear support rod 350 is arranged between the push handle assembly 30 and the rear support 340. The upper end of the rear support rod 350 is rotatably connected to the push handle assembly 30, the middle of the rear support rod 350 is rotatably connected to the rear support 340, and the lower end of the rear support rod 350 is rotatably connected to the end of the connecting rod 360 near the rear support 340. A second crossbar 351 is provided between the rear support rods 350 on both sides of the frame 3. The seat cushion assembly 110 can be movably or fixedly connected to the first crossbar 311 on the front side of the seat support area via a buckle 111, and is connected to the second crossbar 351 on the rear side of the seat support area via a limiting strap 112.

[0142] The support rod 121 is a U-shaped rod, and the connecting part of the seat cover 2 is a channel 21 arranged on both sides of the seat cover 2. The two sides of the support rod 121 pass through the channel 21 to connect with the seat cover 2, ensuring that the position of the support rod 121 is fixed inside the seat cover 2, and at the same time, it can also provide lateral support for the seat cover 2.

[0143] The support rod 121 is located between the backrest panel 122 and the canopy rod 150, and together with the backrest panel 122 and the canopy rod 150, it supports the seat cover 2, thereby forming the internal space of the seat cover 10.

[0144] The seat cover 2 has a folding part. When the folding part is folded up, the seat 10 is in a sitting position. When the folding part is unfolded, the seat 10 is in a lying position.

[0145] When the side bar 130 and the push handle assembly 30 are locked, that is, when the folding joint 133 locks the sub-bar 131 and sub-bar 132, the side bar 130, which is between the push rod 310 and the support rod 121, supports the seat basket 10 away from the frame 3, so that the seat basket 10 is unfolded and mounted on the frame 3 in the opposite direction.

[0146] When folding the stroller, the frame 3 and folding joint 133 need to be unlocked. When the sub-rods 131 and 132 fold together via the folding joint 133, the seat 10 moves towards the push rod 310 via the side rod 130. The frame 3 also folds at the same time, and the push rod 310 is subjected to a downward force, which drives the support assembly 120 and the seat cushion assembly 110 to retract towards the rear support 340. Under the linkage of the rear support rod 350 and the connecting rod 360, the front support 330 also retracts towards the rear support 340, thus completing the folding and collapsing of the stroller.

[0147] Figure 13 The X-shaped rotatable connection between the support rod 121 and the side rod 130 shown can also be applied to cases where the side rod 130 is a folding rod. The portion of the side rod 130 between the rotatable connection point and the rear support rod 350 can be folded. By folding and stretching the side rod in this portion, the distance between the seat and the frame can be adjusted, thereby enabling the seat to be folded up or unfolded for installation.

[0148] See also Figures 21 to 25 The illustration shows a seat and a stroller having the seat according to one embodiment of the present invention.

[0149] The frame 3 is a three-fold frame, including a push handle assembly, a front support assembly, and a rear support assembly. The push handle assembly 30 includes a push rod 310 and a push handle 320, the front support assembly includes a front support 330 and a front wheel, and the rear support assembly includes a rear support 340 and a rear wheel.

[0150] The seat 10 includes a seat frame 1 and a seat cover 2 fitted over the seat frame 1. The seat frame 1 includes a seat cushion assembly 110 and a support assembly 120. The support assembly 120 further includes a backrest 122 and a support rod 121. The backrest 122 is connected to the seat cushion assembly 110 and can rotate relative to it. The support rod 121 is fixed relative to the seat cover 2.

[0151] A side rod 130 is movably connected between the support rod 121 and the push handle assembly 30 of the frame 3. When the side rod 130 and the push handle assembly 30 are locked, the seat 10 is mounted on the frame 3 in the opposite direction via the side rod 130. When the side rod 130 and the push handle assembly 30 are unlocked, the seat 10 moves closer to the push handle assembly 30 via the side rod 130 and retracts.

[0152] One end of the side rod 130 is rotatably connected to the support rod 121, and the other end is rotatably connected to the push rod 310 of the push handle assembly 30 via a connecting block 134. The connecting block 134 can at least partially expose the seat cover 2, rather than being completely covered by the seat cover 2, thereby facilitating installation and removal.

[0153] The side bar 130 is a telescopic bar, comprising two segments 135 and 136 that can slide and extend relative to each other. When segments 135 and 136 move in opposite directions, the side bar 130 extends, and the seat 10 is deployed away from the frame 3; when segments 135 and 136 move towards each other, the side bar 130 retracts, and the seat 10 moves closer to the frame 3 and closes in.

[0154] The intersection of the push handle assembly, front support assembly, and rear support assembly on both sides of the frame 3 forms the seat support area, which is supported by a first crossbar 311 connecting the intersection of the two sides. A rear support rod 350 is arranged between the push handle assembly 30 and the rear support 340. The upper end of the rear support rod 350 is rotatably connected to the push handle assembly 30, the middle of the rear support rod 350 is rotatably connected to the rear support 340, and the lower end of the rear support rod 350 is rotatably connected to the end of the connecting rod 360 near the rear support 340. A second crossbar 351 is provided between the rear support rods 350 on both sides of the frame 3. The seat cushion assembly 110 can be movably or fixedly connected to the first crossbar 311 on the front side of the seat support area via a buckle 111, and is connected to the second crossbar 351 on the rear side of the seat support area via a limiting strap 112.

[0155] The support rod 121 is a U-shaped rod, and the connecting part of the seat cover 2 is a channel 21 arranged on both sides of the seat cover 2. The two sides of the support rod 121 pass through the channel 21 to connect with the seat cover 2, ensuring that the position of the support rod 121 is fixed inside the seat cover 2, and at the same time, it can also provide lateral support for the seat cover 2.

[0156] The support rod 121 is located between the backrest panel 122 and the canopy rod 150, and together with the backrest panel 122 and the canopy rod 150, it supports the seat cover 2, thereby forming the internal space of the seat cover 10.

[0157] The seat cover 2 has a folding part. When the folding part is folded up, the seat 10 is in a sitting position. When the folding part is unfolded, the seat 10 is in a lying position.

[0158] When the side rod 130 and the push handle assembly 30 are locked, that is, when the rod segments 135 and 136 do not retract to each other, the side rod 130 is in a stretched state between the support rod 121 and the push rod 310. The side rod 130 supports the seat 10 away from the frame 3, so that the seat 10 is unfolded and mounted on the frame 3 in the opposite direction.

[0159] When folding the stroller, the frame 3 needs to be unlocked and the locking between the side rod 130 and the push rod 310 released. Rods 135 and 136 are slid together to retract, causing the side rod 130 to be in a retracted state between the support rod 121 and the push rod 310. The retraction of the side rod 130 causes the seat 10 to move closer to the frame 3 and fold together. Simultaneously, the frame 3 folds, and the push rod 310 experiences a downward force, causing the support assembly 120 and the seat cushion assembly 110 to fold together towards the rear support 340. Under the combined action of the rear support rod 350 and the connecting rod 360, the front support 330 also folds together towards the rear support 340, thus completing the folding and collapsing of the stroller.

[0160] Alternatively, the opening and closing of the seat 10 can be achieved in other ways. For example, by unfolding the support assembly 120 away from the push rod 310, the seat 10 unfolds away from the frame 3. At this time, the rod segments 135 and 136 are stretched in opposite directions, so that the side rod 130 is fully stretched between the support rod 121 and the push rod 130, providing support for the seat 10. When it is necessary to close the seat 10, the support assembly 120 is closed towards the push rod 310, and the seat 10 moves closer to the frame 3. At this time, the rod segments 135 and 136 are contracted in opposite directions, so that the side rod 13 is contracted between the support rod 121 and the push rod 130, and the seat 10 moves closer to the push rod 130.

[0161] Figure 13 The X-shaped rotatable connection between the support rod 121 and the side rod 130 shown can also be applied to cases where the side rod 130 is a telescopic rod. The portion of the side rod 130 between the rotatable connection point and the rear support rod 350 is telescopic. By extending or retracting this portion of the side rod, the distance between the seat and the frame can be adjusted, thereby enabling the seat to be folded or unfolded for installation.

[0162] See Figures 26 to 33The illustration shows a baby stroller according to one embodiment of the present invention. The stroller includes a seat 10 and a frame 4, with the seat 10 mounted in reverse on the frame 4.

[0163] The frame 4 is a two-fold frame, including a push handle assembly 30, a front support assembly, and a rear support assembly. The push handle assembly 30 can be a one-piece push handle or a telescopic push handle. The front support assembly includes a front support 330 and a front wheel, and the rear support assembly includes a rear support 340 and a rear wheel.

[0164] The seat 10 includes a seat frame and a seat cover fitted over the seat frame. The seat frame includes a seat cushion assembly 110 and a support assembly 120. The support assembly 120 further includes a backrest 122 and a support rod 121. The backrest 122 is connected to the seat cushion assembly 110 and is rotatable relative to it. The support rod 121 is fixed relative to the seat cover.

[0165] A side rod 130 is movably connected between the support rod 121 and the push handle assembly 30 of the frame 4. When the side rod 130 and the push handle assembly 30 are locked, the seat 10 is mounted on the frame 4 in the opposite direction via the side rod 130. When the side rod 130 and the push handle assembly 30 are unlocked, the seat 10 moves closer to the push handle assembly 30 via the side rod 130 and retracts.

[0166] Among them, a first crossbar 311 is provided between the lower ends of both sides of the push handle assembly 30 and the rotatable connection between the front bracket 330 and the rear bracket 340. The seat cushion assembly 110 is installed on the first crossbar 311 by a buckle 111. When the buckle is rotated, the seat cushion assembly 110 can also rotate relative to the first crossbar 311.

[0167] The support rod 121 is inserted into the channel of the seat cover to ensure that the position of the support rod 121 remains unchanged inside the seat cover.

[0168] See Figures 26 to 27 The side bar 130 is a telescopic bar, which includes bar segments 135 and 136 that can extend and retract relative to each other. The relative extension and retraction of the bar segments 135 and 136 between the support bar 121 and the push handle assembly 30 is used to link the unfolding or folding of the seat basket 10 relative to the frame 4.

[0169] See Figures 28 to 29 The side bar 130 is a folding bar, including sub-bars 131 and 132. Sub-bars 131 and 132 have a folding joint 133. The folding or straightening of the sub-bars 131 and 132 between the support rod 121 and the push handle assembly 310 is used to link the folding or unfolding of the seat basket 10 relative to the frame 4.

[0170] See Figures 30 to 31The side rod 130 is connected to the push handle assembly 30 via a sliding connector 140, and the side rod 130 can slide along the push handle assembly 30 when the sliding connector 140 is unlocked. The push handle assembly 30 may also be provided with a sliding locking member 312 for limiting and locking the sliding connector 140.

[0171] When the side bar 130 and the push handle assembly 30 are in the locked state, that is, the sliding locking member 312 locks the sliding connector 140, so that the sliding connector 140 together with the side bar 130 is kept in the locked position of the push handle assembly 30 and cannot slide relative to the push handle assembly 30. Thus, the side bar 130 supports the seat 10 away from the frame 4, so that the seat 10 is unfolded and mounted on the frame 4 in the opposite direction.

[0172] When folding the stroller, the frame 4 needs to be unlocked and the locking between the side bar 130 and the push handle assembly 30 needs to be released. The sliding connector 140 slides along the push handle assembly 30, and the support assembly 120 moves closer to the push handle assembly 30 to retract. The frame 4 is also folding at the same time. The push handle assembly 30 is subjected to a downward force, which causes the support assembly 120 and the seat assembly 110 to retract towards the rear support 340. The front support 330 also retracts towards the rear support 340, thus completing the folding and collapsing of the stroller.

[0173] After folding, refer to Figure 32 and Figure 33 The push handle assembly 30 is folded and stowed behind the rear support 340, the front support 330 is stowed in front of the rear support 340, and the support assembly 120 and the seat assembly 110 are folded and stowed along with the frame 4 and stowed behind the push handle assembly 30.

[0174] In some other examples, Figure 13 The seat shown, with its X-shaped connection between the side rod 130 and the support rod 121, can also be used for Figures 26 to 31 The two-fold trolley shown.

[0175] The seat structure of this utility model is novel and simple. The side rod provides connection and support for the reverse installation of the seat to the frame, which can realize quick assembly and disassembly of the seat. The operation is convenient and quick, and it greatly reduces production and maintenance costs.

[0176] The seat of this invention can be used as an accessory for baby strollers, serving as a rear-facing seat (seat facing backward). The rear-facing seat design not only enhances parent-child interaction and sense of security, but also improves safety by reducing strong winds or direct sunlight. If obstacles (such as steps or walls) are encountered during the stroller, the baby's body is supported by the backrest, reducing the risk of forward momentum.
