[0041] See Figures 1 to 3 The illustration shows a child seat 100 provided in the first embodiment of the present invention. The child seat 100 is described using a stroller 1000 as an example. The child seat 100 is mounted on a frame 200. It is understood that the child seat 100 can also be used in various suitable child vehicles such as child safety seats, infant carriers, etc. As shown in the figure, the child seat 100 may include a seat body 1, a first shoulder strap 41 and a second shoulder strap 42, a first shoulder strap buckle 51 and a second shoulder strap buckle 52, a first waist belt 61 and a second waist belt 62, a crotch strap assembly 2, and a crotch strap buckle 3. That is, a five-point harness system is configured on the seat body 1.

[0042] See Figure 1 and Figure 3 The seat body 1 may include a seat cushion 11 and a backrest 12. The seat cushion 11 is used to support the child's buttocks, and the backrest 12 is used to support the child's back. The first shoulder strap 41 and the second shoulder strap 42 are respectively connected to the upper sides of the backrest 12, and the first waist belt 61 and the second waist belt 62 are respectively connected to the lower sides of the backrest 12. The first shoulder strap 41 and the first waist belt 61 are respectively connected to the holes 341 and 361 of the first shoulder strap buckle 51, and the second shoulder strap 42 and the second waist belt 62 are respectively connected to the holes 342 and 362 of the second shoulder strap buckle 52.

[0043] The seat cushion 11 has a crotch strap connection 110 in the middle. The crotch strap assembly 2 is connected to the crotch strap connection 110, and the crotch strap buckle 3 is adjustablely connected to the crotch strap assembly 2, allowing the distance between the crotch strap buckle 3 and the crotch strap connection 110 to change. It should be noted that the distance between the crotch strap buckle 3 and the crotch strap connection 110 refers to the straight-line distance between the crotch strap buckle 3 and the crotch strap connection 110 when the crotch strap buckle 3 is pulled outwards. The distance between the crotch strap buckle 3 and the crotch strap connection 110 can also be called the height of the crotch strap buckle 3, and the greater or lesser distance corresponds to the height of the crotch strap buckle 3. Therefore, when a child is seated in the child seat 100, in addition to the adjustable lengths of the shoulder straps and lap belts, the height of the crotch strap buckle 3 can also be adjusted, providing more adjustment options for the five-point harness system and allowing the child seat 100's harness system to better accommodate children of different body types. It should be noted that although... Figure 1 The child seat 100 shown is equipped with a five-point harness system, but the aforementioned crotch strap buckle 3 and crotch strap assembly 2 are also applicable to a three-point harness system that includes two shoulder straps and a crotch strap.

[0044] See Figure 1 and 2 This embodiment illustrates a preferred implementation of the crotch strap assembly 2, which may include a first crotch strap guard 21 and an adjusting strap 23. The first crotch strap guard 21 is connected to the crotch strap connection portion 110, for example, at its bottom by sewing. The adjusting strap 23 is connected to the first crotch strap guard 21, preferably at the front of the first crotch strap guard 21 to prevent contact with the child. The crotch strap buckle 3 is adjustablely connected to the adjusting strap 23. The first crotch strap guard 21 may have an appropriate width to provide a sufficiently large contact area for the child; in some embodiments, the width of the first crotch strap guard 21 is narrowest at its bottom, with the narrowest point W being, for example, not less than 50 mm. The adjusting strap 23 may be made of webbing and have a relatively narrow width. The crotch strap buckle 3 is adjustablely connected to the adjusting strap 23, allowing the distance between the crotch strap buckle 3 and the crotch strap connection portion 110 to be changed.

[0045] See Figure 1 and 2This embodiment illustrates a preferred connection method between the crotch strap buckle 3 and the adjusting belt 23. The adjusting belt 23 is arranged along the longitudinal direction of the first crotch strap guard 21 at the middle of the first crotch strap guard 21, and the longitudinal length of the adjusting belt 23 is less than the longitudinal length H of the first crotch strap guard 21. The first end 23a and the second end 23b of the adjusting belt 23 are respectively connected to the first crotch strap guard 21, for example, by sewing. The lower edge of the crotch strap buckle 3 includes an adjusting buckle portion 31, which is adjustablely mounted on the adjusting belt 23. When the crotch strap buckle 3 is not adjusted, the position of the adjusting buckle portion 31 on the adjusting belt 23 can remain relatively fixed, and a certain distance is maintained between the crotch strap buckle 3 and the crotch strap connecting portion 110. When the crotch strap buckle 3 is adjusted, the adjusting buckle portion 31 can be moved along the adjusting belt 23 to a suitable position, so that the distance between the crotch strap buckle 3 and the crotch strap connecting portion 110 is adjusted to a suitable distance.

[0046] See Figure 3 This diagram illustrates a preferred embodiment of the adjusting buckle 31, located at the edge of the body of the crotch strap buckle 3. It is, for example, a four-position buckle (also called a tic-tac-toe buckle), comprising a mounting hole 310 and two spaced crossbars 311 within the mounting hole 310. The two crossbars 311 divide the mounting hole 310 into a first through hole 3111, a second through hole 3112, and a third through hole 3113. The adjusting strap 23 passes sequentially through the first through hole 3111, the second through hole 3112, and the third through hole 3113, and then wraps around the two crossbars 311 as it passes through these through holes. This structure of the adjusting buckle 31 offers advantages such as simple structure and low cost, and its position on the adjusting strap 23 is easily adjustable. When the position of the adjusting buckle 31 on the adjusting strap 23 is adjusted to a suitable position, the adjusting buckle 31 can reliably engage with the adjusting strap 23, preventing undesirable displacement relative to the adjusting strap 23.

[0047] See Figures 4 to 6 The image shows a child seat 100 provided in the second embodiment of the present invention. This embodiment is a variation of the first embodiment described above. The differences between this embodiment and the first embodiment described above are mainly described below.

[0048] Depend on Figures 4 to 6As can be seen, the crotch strap buckle 3 includes a connecting hole 301, which is located at the lower edge of the crotch strap buckle 3. The first end 23a of the adjusting strap 23 is connected, for example, to the bottom of the first crotch strap guard 21, and the second end 23b passes through the connecting hole 301 and then folds back to connect to the appropriate position of the adjusting strap 23. In this text, the corner position where the second end 23b folds back is referred to as the folding position of the second end 23b. It can be understood that the crotch strap buckle 3 slides to the folding position of the second end 23b of the adjusting strap 23 in use and connects to each shoulder strap buckle. Thus, by connecting the second end 23b to different positions of the adjusting strap 23, the folding position of the second end 23b can be changed, that is, the distance between the crotch strap buckle 3 and the crotch strap connecting part 110 can be changed.

[0049] Figure 5 The diagram illustrates a connection method between the second end 23b of the adjusting band 23 and the adjusting band 23 after folding back. A hook and loop fastener 233 is provided near the first end 23a of the adjusting band 23, and a hook and loop fastener 234 is provided near the second end 23b of the adjusting band 23. The hook and loop fastener 234 and the hook and loop fastener 233 are detachably adhered together. By changing the adhesion position of the hook and loop fastener 234 and the hook and loop fastener 233, the folding position of the second end 23b can be changed.

[0050] Figure 6 Another connection method is shown where the second end 23b of the adjustment band 23 is connected to the adjustment band 23 after being folded back. The adjustment band 23 is provided with at least one protrusion 231 and a plurality of adjustment holes 232. For example, multiple protrusions 231 may be provided and positioned close to the second end 23b of the adjustment band 23, with the multiple protrusions 231 spaced apart along the longitudinal direction of the adjustment band 23. The multiple adjustment holes 232 are positioned close to the first end 23a of the adjustment band 23, with the multiple adjustment holes 232 spaced apart along the longitudinal direction of the adjustment band 23. The multiple protrusions 231 and the multiple adjustment holes 232 can be selectively engaged, i.e., the folded-back position of the second end 23b can be changed. In some embodiments not shown, the multiple protrusions 231 and the multiple adjustment holes 232 may be replaced with a snap-on structure or a button structure.

[0051] Reference Figure 4 and Figure 7Preferably, the first crotch strap guard 21 may also be configured with a limiting structure. The limiting structure is used to limit the left and right movement range of the adjusting belt 23 and the crotch strap buckle 3 relative to the first crotch strap guard 21. This can prevent the adjusting belt 23 and the crotch strap buckle 3 from sliding out of the range of the first crotch strap guard 21 in the left and right direction (corresponding to the width direction of the first crotch strap guard 21) and coming into direct contact with the child. In this embodiment, the limiting structure may include a blocking part 293 and a movable sleeve 294. The blocking part 293 is located in front of the first crotch strap guard 21, and the two side edges of the blocking part 293 are fixed to the first crotch strap guard 21, for example, by sewing. The movable sleeve 294 is connected to the upper edge of the blocking part 293, for example, by sewing, and is fitted over the outside of the first crotch strap guard 21. The adjusting strap 23 can pass through the space between the front side of the first crotch strap guard 21 and the blocking part 293, and between the front side of the first crotch strap guard 21 and the movable sleeve 294. The crotch strap buckle 3 can be located between the front side of the first crotch strap guard 21 and the movable sleeve 294. The movable sleeve 294 can be folded downwards to facilitate the user's adjustment of the adjusting strap 23 and the crotch strap buckle 3. Preferably, the movable sleeve 294 may include a shield 2941 located in front of the first crotch strap guard 21 and an elastic band 2942 located behind the first crotch strap guard 21. The use of the elastic band 2942 allows the diameter of the movable sleeve 294 to be elastically increased or decreased.

[0052] See Figure 8 The image shows a child seat 100 provided in the third embodiment of the present invention. This embodiment is a variation of the second embodiment described above. The differences between this embodiment and the second embodiment described above are mainly described below.

[0053] In this embodiment, an adjusting buckle 24 is installed in the middle of the adjusting belt 23. The first end 23a of the adjusting belt 23 is connected to the bottom of the first crotch strap guard 21, for example. The second end 23b of the adjusting belt 23 passes through the connecting hole 301 of the crotch strap buckle 3 and then folds back to connect with the adjusting buckle 24. By changing the position of the adjusting buckle 24 on the adjusting belt 23, the folding position of the second end 23b can be changed, thereby changing the distance between the crotch strap buckle 3 and the crotch strap connecting part 110. It can be understood that the adjusting buckle 24 can be configured such that when no adjustment operation is performed on the adjusting buckle 24, the position of the adjusting buckle 24 on the adjusting belt 23 remains relatively fixed. When the adjusting buckle 24 is adjusted, the adjusting buckle 24 can move along the adjusting belt 23 to a suitable position, so that the crotch strap buckle 3 and the crotch strap connecting part 110 are at a suitable distance.

[0054] See Figure 9The diagram illustrates a preferred embodiment of the adjusting buckle 24, which is, for example, a three-position buckle (also known as a D-ring buckle), comprising a rectangular frame 241 and a crossbeam 242 located in the middle of the rectangular frame 241. The crossbeam 242 divides the central hole of the rectangular frame 241 into a first half-hole 2411 and a second half-hole 2412. The second end 23b of the adjusting strap 23 passes sequentially through the first half-hole 2411, the second half-hole 2412, and the connecting hole 301 before connecting to the crossbeam 242.

[0055] Additionally, see Figure 8 and Figure 9 In this embodiment, the structure of the connecting hole 301 of the crotch strap buckle 3 is modified based on the connecting hole 301 in the second embodiment described above. For ease of explanation, Figure 9 In the middle, the adjusting belt 23 and the crotch belt buckle 3 are removed from the limiting structure. For example... Figure 9 As shown, a crossbar 3013 is provided in the connecting hole 301, dividing the connecting hole 301 into a first through hole portion 3011 and a second through hole portion 3012. The second end 23b of the adjusting belt 23 passes through the first through hole portion 3011 and the second through hole portion 3012 in sequence and then connects to the crossbeam 242 of the adjusting buckle 24. This configuration of the connecting hole 301 helps to increase the friction between the crotch strap buckle 3 and the adjusting belt 23, thereby helping to prevent relative movement between the crotch strap buckle 3 and the adjusting belt 23.

[0056] See Figures 10 to 12 This embodiment also shows another structure of the crotch strap buckle 3. The crotch strap buckle 3 may be provided with a groove 303 that communicates with the connecting hole 301. The groove 303 has an open end 3030 and a bottom wall (not labeled in the figure) opposite to the open end 3030. The crotch strap buckle 3 also includes a push rod 32 and an elastic member 33. The push rod 32 is inserted into the groove 303 through the open end 3030 to divide the connecting hole 301 into a first through hole portion 3011 and a second through hole portion 3012. The adjusting strap 23 passes through the first through hole portion 3011 and the second through hole portion 3012. The elastic member 33 is used to apply force to the push rod 32 to clamp the adjusting strap 23 between the hole wall of the connecting hole 301 and the push rod 32, so as to effectively prevent the crotch strap buckle 3 from moving relative to the adjusting strap 23. When it is necessary to change the relative position of the crotch belt buckle 3 and the adjusting belt 23, the push rod 32 can be manually operated to overcome the elastic force of the elastic element 33 and move away from the open end 3030, and then the adjusting belt 23 can be pulled freely.

[0057] See Figure 11 and Figure 12The push rod 32 may also be provided with an anti-slip portion 321 protruding toward the open end 3030. The anti-slip portion 321 may have a large coefficient of friction, which can further increase the friction between the adjusting belt 23 and the crotch strap buckle 3. Preferably, the push rod 32 may have a pressing portion 322 extending outside the open end 3030. The pressing portion 322 can be used to easily push the push rod 32, causing the push rod 32 to move away from the open end 3030. In some embodiments, the push rod 32, the anti-slip portion 321, and the pressing portion 322 may be integrally formed.

[0058] In some embodiments, the elastic member 33 may include a first elastic arm extending from the push rod 32 to abut against the bottom wall of the groove 303. Alternatively, as shown in this embodiment, the elastic member 33 may include a second elastic arm extending from the wall of the groove 303 to abut against the push rod 32, and the push rod 32 may be provided with a groove 3202 for receiving the second elastic arm. In other embodiments, the elastic member 33 may be a separate component and clamped between the push rod 32 and the bottom wall of the groove 303.

[0059] See Figure 13 This embodiment illustrates another preferred implementation of the limiting structure. The limiting structure includes two side wings 291 and 292 located on both sides of the first crotch strap guard 21. The two side wings 291 and 292 can be folded relative to the first crotch strap guard 21 and then detachably connected together to enclose the crotch strap adjustment strap 23. In some embodiments, the two side wings 291 and 292 are attached together, for example, by Velcro 2911 and 2922 that cooperate with each other. Alternatively, in other embodiments, the two side wings 291 and 292 can be connected together by snaps or hooks.

[0060] See Figure 14 This embodiment illustrates another preferred implementation of the limiting structure. The limiting structure may include a sleeve 292 movably fitted over the outside of the first crotch strap guard 21, an adjusting strap 23 adapted to pass through the sleeve 292, and the sleeve 292 can be removed from the first crotch strap guard 21.

[0061] It is understood that the limiting structure in this embodiment is also applicable to the second embodiment described above, and the limiting structure in the second embodiment described above is also applicable to this embodiment. It is understood that the limiting structure can have various other implementations, and is not limited to the examples given herein.

[0062] See Figure 15 The image shows a child seat 100 provided in the fourth embodiment of the present invention. This embodiment is a variation of the first embodiment described above. The differences between this embodiment and the first embodiment described above are mainly described below.

[0063] See Figure 15The two ends of the adjusting strap 23 are fixed to the front side of the first crotch strap guard 21, for example. The adjusting strap 23 can be fixed to the first crotch strap guard 21 by sewing it around the perimeter. The adjusting strap 23 is arranged longitudinally along the first crotch strap guard 21. Multiple first adjusting rings 2301 can be provided on the adjusting strap 23, and these rings are spaced apart longitudinally along the adjusting strap 23. Each first adjusting ring 2301 is, for example, a webbing ring or a fabric loop. The crotch strap buckle 3 can be provided with a first connecting hook 391, which selectively engages with one of the multiple first adjusting rings 2301, allowing for convenient detachable adjustment of the distance between the crotch strap buckle 3 and the crotch strap connection 110.

[0064] See Figure 16 This illustration shows a child seat 100 according to a fifth embodiment of the present invention, which is a variation of the fourth embodiment described above. In this embodiment, the crotch strap assembly 2 includes a second crotch strap guard 22, which is connected to the crotch strap connection portion 110, for example, at its bottom position, by means of sewing. Unlike the fourth embodiment, the second crotch strap guard 22 does not have an adjustment strap; instead, for example, a plurality of second adjustment rings 220 are directly provided on the front side of the second crotch strap guard 22, arranged longitudinally along the second crotch strap guard 22. The crotch strap buckle 3 may be provided with a second connecting hook 392, which selectively engages with one of the plurality of second adjustment rings 220, thereby facilitating the adjustment of the distance between the crotch strap buckle 3 and the crotch strap connection portion 110.

[0065] This invention also provides a child vehicle 1000, which may be, for example, but not limited to, a child safety seat, a stroller, or an infant carrier, and may be equipped with the aforementioned child seat 100.
