DETAILED DESCRIPTION OF THE INVENTION

[0071] The crotch belts of typical child carriers cannot be adjusted in length, so when adjusting the child carrier's safety belt (shoulder belt), the crotch belt may be too short and the buckle may be set too low, which affects the comfort and safety of the child when seated.

[0072] Therefore, the present disclosure provides a crotch belt length adjuster that allows the length of the crotch belt to be adjusted at different adjustment positions to accommodate children of different physiques, and allows the adjustment position of the crotch belt to be conveniently and quickly adjusted.

[0073] It should be noted that, as used herein, child carrier refers to a variety of child carrying devices, including, but not limited to, car seats, carts, dining chairs, rocking chairs, etc. For ease of explanation, the child carrier is illustrated as a car seat.

[0074] The present specification will now be described in detail with reference to the accompanying drawings. First embodiment of crotch belt length adjustment device

[0075] 1 to 16 show a child carrier 1 equipped with a crotch belt length adjuster according to a first embodiment of the present disclosure. The child carrier 1 includes a seat portion 10, a backrest, and a headrest. Note that the seat portion 10 in the present disclosure refers to a seat housing.

[0076] A crotch belt length adjustment device 100A according to the present disclosure includes a crotch belt 100 having a first end 101 and a second end 102.

[0077] To adjust the crotch belt 100, the crotch belt length adjustment device 100A further includes a first hole 15, an adjustment hole 12, and a plurality of second holes 13 formed through the seat portion 10 of the child carrier 1.

[0078] As shown in FIGS. 1 to 6 and 9 to 12, the first end 101 of the crotch belt 100 passes through the first hole 15 from the upper surface 11A of the seat 10 and is exposed on the lower surface 11B of the seat 10 (see FIGS. 2, 4, 6, 10, 12, and 16). A first end inhibition member 101A is provided on a portion of the first end 101 exposed on the lower surface 11B (see FIGS. 2, 4, 6, 10, and 12). The first end inhibition member 101A is arranged so that it cannot pass through the first hole 15. In other words, the first end 101 of the crotch belt 100 can be exposed on the lower surface 11B of the seat 10 after passing through the first hole 15, and the first end inhibition member 101A is provided on the exposed portion of the first end 101.

[0079] Therefore, when the first end 101 passes through the first hole 15 from the upper surface 11A of the sheet portion 10, it is not blocked by the first hole 15 due to the first end blocking member 101A. However, after the first end 101 passes through the first hole 15 and is exposed on the lower surface 11B of the sheet portion 10, the exposed portion of the first end 101 is provided with the first end blocking member 101A. This is because the first end blocking member 101A is blocked by the first hole 15 on the lower surface 11B of the sheet portion 10. The first end 101 with the first end 101A cannot pass through the first hole 15 from the lower surface 11B of the sheet portion 10 to the upper surface 11A. As a result, when the middle portion of the crotch belt 100 moves upward, the first end portion 101 can only move upward until it is blocked by the first end portion inhibiting member 101A, thereby ensuring that the first end portion 101 does not come off the seat portion 10 and realizing the connection between the first end portion 101 and the seat portion 10.

[0080] The size of the first end inhibition member 101A can be set to be larger than the first hole 15, so that the first end inhibition member 101A cannot pass through the first hole 15. In the embodiment shown in Figures 1-6, 9-14 and 16, the first end inhibition member 101A is a frame buckle having a central crossbar that is larger than the size of the first hole 15.

[0081] In this embodiment, a "frame buckle having a central crossbar" includes a substantially rectangular ring with at least one central crossbar or the like, although the present disclosure is not limited thereto.

[0082] For example, in another embodiment, the first end inhibition member 101A is a bow knot formed by folding a portion of the crotch belt 100 adjacent to the first end 101 back over itself multiple times, and the bow knot may be larger than the first hole 15 and configured so as not to be able to pass through the first hole 15.

[0083] In some embodiments, the first end inhibition member 101A located below the seat portion 10 sags under its own weight, causing the first end 101 of the crotch belt 100 to sag as well, resulting in the portion of the crotch belt 100 below the seat portion 10 becoming excessively long, which may affect the use of the crotch belt 100.

[0084] 21, a first end stopper structure 101B is provided in a portion adjacent to the first end 101 of the crotch belt 100, and the first end stopper structure 101B is located above the upper surface 11A of the seat portion 10 and is arranged so as not to pass through the first hole 15. Therefore, the first end stopper structure 101B restricts the first end 101 of the crotch belt 100 from dropping downward.

[0085] Specifically, when the first end inhibition member 101A has at least one (two as shown in Figure 15B) first end inhibition member through-slot 101A1, 101A2, as shown in Figure 21, the first end stopper structure 101B is formed by the first end 101 of the crotch belt 100 passing from the upper surface 11A of the seat portion 10 through the first hole 15 and the first end inhibition member through-slot 101A1, 101A2 in order, and then passing through the first hole 15 in the opposite direction to reach above the upper surface 11A of the seat portion 10, and connecting with another portion of the crotch belt 100 located on the upper surface 11A of the seat portion 10.

[0086] To prevent the first end stop structure 101B from passing through the first hole 15, as shown in FIG. 21, the first end stop structure 101B is formed as a half bow knot having wings larger than the first hole 15, and is positioned so that the free end of the half bow knot abuts the upper surface 11A of the sheet portion 10.

[0087] In another embodiment, the first stopper structure 101B may be formed as a bow knot with two wings that are larger than the first hole 15.

[0088] Alternatively, the first end 101 of the crotch belt 100 may be connected to the seat portion 10 in other ways.

[0089] In another embodiment, the crotch belt length adjustment device 100A according to the present disclosure may not have a first hole 15, and a fixing structure such as a hanging hook or a hanging ring is provided on the upper surface 11A of the seat portion 10, and the first end 101 of the crotch belt 100 is connected to this fixing structure so that the first end 101 does not separate from the seat portion 10.

[0090] In yet another embodiment, the first end 101 of the crotch belt 100 may be configured to be removably fastened to the seat portion 10 in only one direction. For example, the first end 101 may be configured to be removably fastened to the seat portion 10 in a downward direction.

[0091] 1 to 6 and 9 to 12, the second end 102 of the crotch belt 100 passes through the adjustment holes 12 from the upper surface 11A to the lower surface 11B of the seat portion 10 (see FIGS. 2, 4, 6, 10, 12, and 16). Thereafter, it passes through one of the second holes 13 from the lower surface 11B to the upper surface 11A and is exposed at the upper surface 11A.

[0092] In the crotch belt length adjustment device 100A according to the present disclosure, the crotch belt 100 is adjusted to different adjustment positions, and conversion between the multiple adjustment positions is achieved using multiple second holes 13. By moving the second end 102 between the different second holes 13, the length of the used portion of the crotch belt 100 can be changed.

[0093] The second end 102 of the crotch belt 100 is exposed on the upper surface 11A of the seat portion 10, which makes it easy for the user to move the second end 102 from one of the second holes 13 to another second hole 13, thereby achieving adjustment to an adjustment position (described below).

[0094] Furthermore, after the second end 102 of the crotch belt 100 passes through the adjustment hole 12 and one second hole 13 in sequence, the moving direction of the second end 102 is different from the moving direction of the middle portion of the crotch belt 100. For example, when the middle portion of the crotch belt 100 moves upward, the second end 102 may move downward.

[0095] 1 to 6 and 9 to 12, a second end inhibiting member 102A is provided on a portion of the second end 102 exposed on the upper surface 11A, and the second end inhibiting member 102A is arranged so as not to pass through the second hole 13. That is, after the second end 102 of the crotch belt 100 is exposed on the upper surface 11A of the seat portion 10 through one second hole 13, the exposed second end 102 is provided with the second end inhibiting member 102A.

[0096] Therefore, when the second end 102 passes through the adjustment hole 12 from the upper surface 11A of the sheet portion 10, and then passes through one of the second holes 13 from the lower surface 11B, the second end 102 is not blocked by the adjustment hole 12 and the second hole 13 due to the second end blocking member 102A. However, after the second end 102 passes through the second hole 13 and is exposed on the upper surface 11A of the sheet portion 10, if the second end blocking member 102A is provided on the exposed portion, the second end blocking member 102A is blocked by the second hole 13 on the upper surface 11A of the sheet portion 10, and therefore the second end blocking member 102A of the second end 102 cannot pass through the second hole 13 from the upper surface 11A of the sheet portion 10 and retract to the lower surface 11B. As a result, when the middle portion of the crotch belt 100 moves upward, the second end portion 102 only moves downward until it is blocked by the second end portion inhibiting member 102A, thereby ensuring that the second end portion 102 does not separate from the seat portion 10.

[0097] The size of the second end inhibition member 102A can be set larger than the size of the second hole 13, thereby preventing the second end inhibition member 102A from passing through the second hole 13. In the embodiment shown in FIGS. 1-6 and 9-12, the second end inhibition member 102A is a frame buckle having a central crossbar that is larger than the second hole 13. Furthermore, to ensure that the frame buckle 102A having the intermediate crossbar abuts more securely against the upper surface 11A of the seat portion 10, a limiting rib 111 is formed around each second hole 13 on the upper surface 11A (see FIGS. 1, 3, 5, 7, 9, 11, and 13). The contour of each limiting rib 111 corresponds to the shape of the frame buckle having the intermediate crossbar 102A, thereby limiting the position of the frame buckle having the intermediate crossbar 102A on the upper surface 11A of the seat portion 10. The limiting rib 111 protrudes from the upper surface 11A of the seat portion 10.

[0098] Of course, the disclosure is not limited to this.

[0099] For example, in another embodiment, the second end inhibition member 102A may be a bow knot formed by folding a portion of the crotch belt 100 adjacent the second end 102 over itself multiple times, and the bow knot is larger than the second hole 13 and therefore cannot pass through the second hole 13.

[0100] Furthermore, the second end 102 of the crotch belt 100 may be connected to the seat portion 10 in other ways.

[0101] In another embodiment, the crotch belt 100 passes through the adjustment holes 12, and the second end 102 of the crotch belt 100 is configured to be releasably secured in one direction to one of the second holes 13. For example, the second end 102 is configured to be releasably secured in an upward direction to one of the second holes 13.

[0102] After the second end 102 passes through the adjustment hole 12, the crotch belt 100 can move in both directions through the adjustment hole 12, so the length of the usable section of the crotch belt 100 between the first end 101 and the adjustment hole 12 can be increased or decreased as needed.

[0103] The use section of the crotch belt 100 refers to the section of the crotch belt 100 located between the first end 101 and the adjustment hole 12. The buckle 20 is slidably connected to the use section of the crotch belt 100, and is used to connect to a safety belt 200 of the child carrier 1, which will be described later.

[0104] Because the crotch belt 100 is not fixedly connected to the adjustment holes 12, the crotch belt 100 can move in both directions through the adjustment holes 200, thereby changing the length of the usable section of the crotch belt 100. The user can increase the length of the usable section of the crotch belt 100 by moving any portion of the usable section of the crotch belt 100 upward until the second end 102 of the crotch belt 100, which is moving downward, is blocked by the second end blocking member 102A. Furthermore, the user passes the second end 102 of the crotch belt 100 through the second holes 13, and the distance between the different second holes 13 and the adjustment holes 12 changes, changing the length of the section of the crotch belt 100 between the second end 102 and the adjustment holes 12. This changes the length of the usable section of the crotch belt 100 accordingly, making it possible to adjust the length of the usable section of the crotch belt 100. Furthermore, because the height of the buckle 20 in the usable section of the crotch belt 100 can be adjusted relative to the seat portion 10, the crotch belt 100 can be adapted to children of various sizes.

[0105] In order to prevent the crotch belt 100 from causing discomfort to a child sitting in the child carrier 1, the crotch belt 100 is usually a flat, wide belt. Correspondingly, as shown in FIGS. 1-6 and 9-12, the first hole 15, the plurality of second holes 13, and the adjustment hole 12 can be formed as elongated holes, respectively, so that the crotch belt 100 can pass through these holes more smoothly. Furthermore, the elongated holes prevent the crotch belt 100 from twisting, thereby preventing a twisted crotch belt 100 from causing discomfort to a child sitting in the child carrier 1.

[0106] The first hole 15, the plurality of second holes 13, and the adjustment hole 12 may have the same shape and size, which facilitates processing.

[0107] In one embodiment, as shown in Figures 7, 8, 13 and 14, the extension directions E of the first hole 15, the multiple second holes 13 and the adjustment hole 12 are parallel to each other and perpendicular to the width direction W of the seat portion 10.

[0108] Furthermore, the first hole 15, the plurality of second holes 13, and the adjustment hole 12 are arranged in parallel and sequentially at intervals along the width direction W of the seat portion 10. In this configuration, the plurality of second holes 13 are located between the first hole 15 and the adjustment hole 12. When the second end 102 of the crotch belt 100 moves from one of the second holes 13 to another second hole 13, the spacing distance between the two second holes 13 is equal to the amount of change in the length of the usage section of the crotch belt 100 at two different adjustment positions, i.e., the adjustment stroke between the two adjustment positions of the crotch belt 100.

[0109] In yet another embodiment, the spacing distance between two adjacent second holes 13 may be 40 mm.

[0110] To make it easier for the user to move the second end 102 of the crotch belt 100 from one of the second holes 13 to another, in the embodiment shown in Figures 1 to 14, the multiple second holes 13 can be connected to each other via connecting holes 14 formed through the seat portion 10. Therefore, the user can move the second end 102 between the multiple second holes 13 via the connecting holes 14 simply by operating the frame buckle having the intermediate crossbar 102A, thereby making it possible to conveniently and quickly adjust the adjustment position.

[0111] As shown in Figures 7, 8, 13 and 14, the connection holes 14 may be arranged as elongated holes and extend in a direction intersecting the extension direction E of the second holes 13. In one embodiment, the connection holes 14 are arranged to extend in a direction perpendicular to the extension direction E of the second holes 13. This configuration can prevent the crotch belt 100 from accidentally slipping off from the first hole 13 to another second hole 13 through the connection holes 14.

[0112] Of course, the present disclosure is not limited thereto. Specifically, the first hole 15, the plurality of second holes 13, and the adjustment hole 12 may be formed as holes of other shapes. Furthermore, their respective extension directions do not have to be parallel to each other or perpendicular to the width direction W of the sheet portion 10. Furthermore, the first hole 15, the plurality of second holes 13, and the adjustment hole 12 may be formed in other arrangements in the sheet portion 10. Furthermore, the spacing distance between two adjacent second holes 13 may be set to 30 mm, 50 mm, or other values ​​as necessary.

[0113] The connecting hole 14 may not be arranged among the multiple second holes 13, and instead, the second end 102 and the second end inhibition member 102A are separated, and the second end 102 retreats from the upper surface 11A of the sheet portion 10 through the second hole 13, retreats to the lower surface 11B, and is exposed from the lower surface 11B to the upper surface through another second hole 13, thereby moving the second end 102 from one of the second holes 13 to another second hole 13, and after the second end 102 is moved to another second hole 13, the second end 102 and the second end inhibition member 102A are connected to each other.

[0114] 1 to 8, examples of the disclosed crotch belt length adjusting device 100A at each adjustment position will be described, exemplifying the plurality of second holes 13 as three second holes 13. For ease of explanation, the three second holes 13 are a first hole 131 at the first adjustment position, a second hole 132 at the second adjustment position, and a third hole 133 at the third adjustment position, thereby allowing the crotch belt length adjusting device 100A to perform adjustment for three adjustment positions.

[0115] 1 and 2, the second end 102 of the crotch belt 100 is exposed through the second hole 131 in the first adjustment position, and is in contact with the upper surface 11A of the seat portion 10 by the second end inhibiting member 102A at the second hole 131 in the first adjustment position. Because the distance between the second hole 131 and the adjustment hole 12 in the first adjustment position is shortest, when the crotch belt 100 is fastened, the length of the section between the second end 102 of the crotch belt 100 and the adjustment hole 12 is shortest, and therefore the usable section of the crotch belt 100 between the first end 101 and the adjustment hole 12 is longest, making it suitable for larger children.

[0116] 3 and 4, the second end 102 of the crotch belt 100 is exposed through the second hole 132 in the second adjustment position and abuts against the upper surface 11A of the seat member 10 by the second end blocking member 102A in the second adjustment position. Because the distance between the second hole 132 and the adjustment hole 12 in the second adjustment position is relatively long, when the crotch belt 100 is fastened, the length of the section of the crotch belt 100 between the second end 102 and the adjustment hole 12 is relatively long. Accordingly, the usable section of the crotch belt 100 between the first end 101 and the adjustment hole 12 is relatively short, which may be suitable for children of medium body size.

[0117] 5 and 6, the second end 102 of the crotch belt 100 is exposed through the second hole 133 in the third adjustment position, and is attached to the upper surface 11A of the seat member 10 by the second end blocking member 102A at the second hole 133 in the third adjustment position. Because the distance between the second hole 133 and the adjustment hole 12 is the farthest in the third adjustment position, when the crotch belt 100 is fastened, the length of the section of the crotch belt 100 between the second end 102 and the adjustment hole 12 is the longest, and therefore the usable section of the crotch belt 100 between the first end 101 and the adjustment hole 12 is the shortest, which may be suitable for children with small body sizes.

[0118] The plurality of second holes 13 can include two or more second holes to meet different practical requirements.

[0119] For example, Figures 9-14 show an embodiment in which the multiple second holes 13 are implemented as two second holes 13 (i.e., second hole 131 in a first adjustment position and second hole 132 in a second adjustment position).

[0120] Compared with the above embodiment with three second holes 13, the number of second holes 13 in this embodiment is reduced to two, so that the crotch belt length adjustment device 100A can perform adjustment for two adjustment positions.

[0121] Furthermore, when there are two second holes 13, the connecting hole 14 between the two second holes 13 can be arranged longer, and therefore, it can be more effective to prevent the crotch belt 100 from accidentally sliding from one of the second holes 13 to another second hole 13 via the connecting hole 14.

[0122] To make the child carrier 1 more beautiful and comfortable, the seat portion 10 is provided with a removable cushion, which covers the upper surface 11A of the seat portion 10. When it is necessary to perform an adjustment for adjusting the position of the crotch belt length adjuster 100A, the user can remove the cushion and thereby operate the frame buckle having the central crossbar 102A to move the second end 102 between the plurality of second holes 13 through the connecting holes 14.

[0123] In the process of using the crotch belt length adjustment device 100A, the thickness T of the second end inhibition member 102A may be smaller than the width B13 of the second end hole 13 or the width B14 of the connecting hole 14, so that the second end inhibition member 102A and the second end 102 of the crotch belt 100 connected thereto can unexpectedly pass through the second hole 13 or the connecting hole 14, resulting in the second end inhibition member 102A of the crotch belt 100 and its connected second end 102 falling below the lower surface 11B of the seat portion, and the user cannot adjust the crotch belt 100.

[0124] To avoid such accidental collapse, in the embodiment, the thickness T of the second end inhibition member 102A (see FIG. 15A) is arranged to be larger than the width B13 of the second hole 13 (see FIGS. 8, 13, and 14) and larger than the width B14 of the connection hole 14 (see FIGS. 8, 13, and 14).

[0125] In the specifications, the width B13 of the second hole 13 and the width B14 of the connection hole 14 refer to the smallest of the opening sizes of the second hole 13 and the connection hole 14, respectively, such as the widths shown in Figures 8, 13, and 14.

[0126] The thickness T of the second end inhibitor 102A refers to the smallest dimension of the overall external dimensions of the second end inhibitor 102A, such as the thickness T of the frame buckle with a central crossbar 102A shown in FIG. 15A.

[0127] Since the thickness T of the second end inhibition member 102A is the smallest in the overall external size, if the minimum size (i.e., thickness T) of the second end inhibition member 102A is larger than the width B13 of the second end hole 13 and the width B14 of the connecting hole 14, the second end inhibition member 102A cannot pass through the second end hole 13 or the connecting hole 14, thereby avoiding the above-mentioned accidental dropping.

[0128] It should be understood that in the embodiment shown in Figure 15A, the thickness T of the second end obstruction element 102A can refer to the thickness of the second end obstruction element 102A itself. In other embodiments, the thickness T of the second end obstruction element 102A can be the overall thickness of the second end obstruction element 102A, formed by welding, screwing, riveting, gluing, etc., or by adding thickened portions (not shown), such as bosses or pins, to the second end obstruction element 102A.

[0129] 16 to 20, the portion of the second end 102 of the crotch belt 100 exposed on the upper surface 11A may form a multi-layer folded structure 102B. That is, the portion of the second end 102 of the crotch belt 100 exposed on the upper surface 11A is folded over itself multiple times and maintained in the folded state by sewing, bonding, or the like.

[0130] The second end inhibition member 102A may be disposed on the multilayer folding structure 102B such that the combined thickness of the second end inhibition member 102A and the multilayer folding structure 102B is greater than the width B13 of the second hole 13 and the width B14 of the connecting hole 14. As a result, the second end inhibition member 102A is connected to the multilayer folding structure 102B and cannot pass through the second hole 13 or the connecting hole 14, thereby preventing the above-mentioned accidental dropping.

[0131] In one embodiment, the second edge blocking member 102A is disposed between the upper surface 11A and the multilayer folded structure 102B, and the multilayer folded structure 102B may have a thickness greater than the width B13 of the second hole 13 and greater than the width B14 of the connecting hole 14. This prevents the multilayer folded structure 102B from passing through the second hole 13 or the connecting hole 14, thereby preventing the multilayer folded structure 102B from accidentally dropping.

[0132] In the embodiment of FIGS. 16 to 20, the multi-layer folded structure 102B is a bow knot, which is more aesthetically pleasing.

[0133] 16 to 20, the bow knot has two wings 102B1 and 102B2. By using the wings 102B1 and 102B2 to greatly expand the size of the multiple multi-layer folded structures 102B, not only the thickness but also the length of the multiple multi-layer folded structures 102B can be made larger than the width B13 of the second hole 13 and the width B14 of the connecting hole 14. On the other hand, in the open state, even if the thickness is relatively thin, the length of the multiple multi-layer folded structures 102B is longer than the width B13 of the second hole 13 and the width B14 of the connecting hole 14. This prevents the multiple multi-layer folded structures 102B from passing through the second hole 13 or the connecting hole 14.

[0134] Of course, the present application is not limited to this.

[0135] The wings can be made separately and connected to the multi-folded structure 102B.

[0136] The material of the wings 102B1, 102B2 may be the same as that of the multi-layered folded structure 102B. For example, a part of the crotch belt 100 may be the multi-layered folded structure 102B, and another part may be a ring-shaped structure extending from the multi-layered folded structure 102B, and the ring-shaped structure may constitute the wings 102B1, 102B2.

[0137] Furthermore, the material of the wings 102B may be different from the material of the multi-layered folding structure 102B, and for example, the wings 102B made of a different material may be connected to the multi-layered folding structure 102B by sewing, gluing, or the like.

[0138] In one embodiment, the thickness T of the second end inhibition member 102A, the thickness of the multi-layer folding structure 102B, or the sum of the thickness T of the second end inhibition member 102A and the thickness of the multi-layer folding structure 102B is greater than the width B13 of the second hole 13, thereby preventing the second end inhibition member 102A and the second end 102 of the crotch belt 100 connected thereto from accidentally passing through the second hole 13 and falling below the lower surface 11B of the seat portion 10.

[0139] In one embodiment, the thickness T of the second end inhibition member 102A, the thickness of the multi-layer folding structure 102B, or the sum of the thickness of the second end inhibition member 102A and the thickness of the multi-layer folding structure 102B is greater than the width B14 of the connection hole 14, thereby preventing the second end inhibition member 102A and the second end 102 of the crotch belt 100 connected thereto from accidentally passing through the connection hole 14 and falling off from the lower surface 11B of the seat portion 10.

[0140] Furthermore, if the second end inhibition member 102A, such as a frame buckle having an intermediate crossbar, and the multi-layer folding structure 102B are not fixed together, when the user adjusts the crotch belt 100, the thickness T of the second end inhibition member 102A is smaller than the width B13 of the second hole 13 or the width B14 of the connecting hole 14, and therefore there is a risk that the second end inhibition member 102A may mistakenly pass through the second hole 13 or the connecting hole 14 and fall below the seat portion 10.

[0141] The present application provides a mechanism for holding the multi-layer folded structure 102B and the second end inhibition member 102A together to prevent the second end inhibition member 102A from falling below the seat portion 10.

[0142] Specifically, the second end inhibition member 102A has at least one (two in Figure 15) second end inhibition member through-slot 102A1, 102A2, and the multi-layer folded structure 102B has at least one (two in Figures 16 to 20) wing portion 102B1, 102B2, and the wing portions 102B1, 102B2 are arranged to pass through the second end inhibition member through-slot 102A1, 102A2, as shown in Figures 19 and 20, thereby holding the multi-layer folded structure 102B and the second end inhibition member 102A together, and the second end inhibition member 102A cannot pass through only the second hole 13 or the connecting hole 14, but can fall below the sheet portion 10.

[0143] Of course, if the multi-layered folding structure 102B has multiple wing portions, the multiple wing portions may each pass through a different second end inhibitor member through slot, or the multiple wing portions may all pass through the same second end inhibitor member through slot. Second embodiment of crotch belt length adjustment device

[0144] 22A to 28 show a child carrier 1 employing a crotch belt length adjusting device 100A according to a second embodiment of the present invention.

[0145] The second embodiment of the crotch belt length adjusting device 100A according to the present application also includes a crotch belt 100 having a first end 101 and a second end 102.

[0146] The first end 101 of the crotch belt 100 can be connected to the seat portion 10 of the child carrier 1 in various ways. For example, a fixing structure such as a hanging hook, a hanging ring, or a hole may be provided on the lower surface 11B of the seat portion 10, and the first end 101 of the crotch belt 100 may be connected to the fixing structure so that the first end 101 does not come off the seat portion 10.

[0147] 22A to 28 show an embodiment in which the first end 101 of the crotch belt 100 is connected to the seat portion 10 of the child carrier 1. In one embodiment, the first end 101 of the crotch belt 100 is detachably fixed to the seat portion 10 in one direction. For example, the first end 101 may be detachably fixed to the seat portion 10 in an upward direction.

[0148] Here, the crotch belt length adjusting device 100A further has a first hole 15 formed so as to penetrate the seat portion 10 (see FIGS. 24 to 26, 28). A first end portion 101 of the crotch belt 100 is exposed from the lower surface 11B of the seat portion to the upper surface 11A of the seat portion through the first hole 15. A first end portion inhibiting member 101A (see 22A, 22B, 23, 26) is provided at the portion of the first end portion 101 exposed at the upper surface 11A of the seat portion 10, which prevents the first end portion 101 from passing through the first hole 15 from the upper surface 11A of the seat portion 10 and retracting below the lower surface 11B, thereby preventing the first end portion 101 from detaching from the seat portion 10 and realizing the connection between the first end portion 101 and the seat portion 10. Furthermore, the first end 101 of the crotch belt 100 is exposed on the upper surface 11A of the seat portion 10 after passing through the first hole 15, and a first end inhibition member 101A is provided on the exposed portion.

[0149] The first end inhibition member 101A in the second embodiment may be the same as or different from the first end inhibition member 101A in the first embodiment. For example, the first end inhibition member 101A may be a frame buckle with an intermediate crossbar or a multi-layer folding structure larger than the first hole 15.

[0150] In one embodiment, the first end inhibition member 101A is arranged with a length and width greater than the width of the first hole 15 so that it cannot pass through the first hole 15 along the normal direction of the plane formed by the longitudinal edge and width edge of the first end inhibition member 101A, and the first end inhibition member 101A is obstructed by the first hole 15 on the upper surface 11A of the sheet portion 10, so that the first end 101 on which the first end inhibition member 101A is provided cannot pass through the first hole 15.

[0151] In this embodiment, the sum of the thickness of the first end inhibition member 101A and the thickness of the crotch belt 100 may be greater than or equal to the width of the first hole 15. If the sum of the thicknesses of the first end inhibition member 101A and the crotch belt 100 is greater than the width of the first hole 15, the overall dimensions (length, width, and thickness) of the first end inhibition member 101A and the crotch belt 100 are all greater than the width of the first hole 15. Therefore, the first end inhibition member 101A arranged together with the crotch belt 100 cannot pass through the first hole 15 at any angle, and the first end 101 of the crotch belt 100 must be separated from the first end inhibition member 101A before passing through the first hole 15. When the sum of the thicknesses of the first end inhibition member 101A and the crotch belt 100 is equal to the width of the first hole 15, preferably smaller than the width of the first hole 15, the first end inhibition member 101A arranged together with the crotch belt 100 can pass through the first hole 15 along the thickness direction of the first hole 15, so that the crotch belt 100 provided with the first end inhibition member 101A can be selectively inhibited by the first hole 15 or passed through the first hole 15 without being separated from the first end inhibition member 101A, which is useful for connecting and disconnecting the first end 101 of the crotch belt 100 to the seat portion 10.

[0152] The crotch belt length adjusting device 100A of the second embodiment also has a plurality of second holes 13 penetrating the seat portion 10 for adjusting the crotch belt 100.

[0153] As shown in Figures 22A to 28, the second end 102 of the crotch belt 100 is exposed from the lower surface 11B of the seat portion 10 to the upper surface 11A of the seat portion 10 through the second hole 13 and is connected to the safety belt 200 of the child carrier 1.

[0154] In the present application, the second end 102 of the crotch belt 100 can be connected to the safety belt 200 of the child carrier 1 in various common ways. For example, in the embodiment shown in Figures 22A and 22B, the buckle 20 is provided at the second end 102 of the crotch belt 100, and the connecting clap 40 is disposed between the first end 201 and the second end 202 of the safety belt 200 (see Figure 22B), and the second end 102 of the crotch belt 100 can be connected to the safety belt 200 by engagement of the connecting clap 40 with the buckle 20. Of course, the buckle 20 does not necessarily have to be disposed at the second end 102, and may be disposed at another position of the portion of the crotch belt 100 exposed from the upper surface 11A of the seat portion 10.

[0155] In the second embodiment of the crotch belt length adjusting device 100A according to the present application, the crotch belt 100 is also adjusted at each adjustment position, and conversion between the multiple adjustment positions is realized using multiple second holes 13. By moving the crotch belt 100 between different second holes 13, the length of the used portion of the crotch belt 100 can be changed differently.

[0156] In both the first and second embodiments of the crotch belt length adjusting device 100A, the length of the usage session of the crotch belt 100 is adjusted by changing the length of a hidden section 1001 (described later) of the crotch belt 100 that is hidden under the seat part 10. However, the crotch belt length adjusting device 100A of the second embodiment differs from the first embodiment in the following points.

[0157] 1. The crotch belt length adjustment device 100A of the second embodiment can accommodate children of different body sizes by changing the position of the crotch belt 100 that protrudes along the front-to-back direction perpendicular to the width direction of the seat portion 10, and can also adjust the length of the used portion of the crotch belt 100 and the position of the crotch belt 100 in the front-to-back direction of the seat portion 10 by exposing the second end 102 of the crotch belt 100 to the upper surface 11A of the seat portion 10 through a different second hole 13.

[0158] 2. Due to differences in structure, in the second embodiment, the used portion of the crotch belt 100 refers to the portion of the crotch belt 100 between the second holes 13 of the second end 102, i.e., the portion of the crotch belt 100 exposed on the upper surface 11A of the seat portion 10.

[0159] In the crotch belt length adjusting device 100A of the second embodiment, the position of the crotch belt 100 can also be adjusted by moving the crotch belt 100 from one second hole 13 to the other second hole 13.

[0160] That is, because the crotch belt 100 is not fixedly connected to the second hole 13, the crotch belt 100 can move in both directions through the second hole 13, which may change the length of a usage session of the crotch belt 100. The user can increase the length of the usage section of the crotch belt 100 by moving the second end 102 of the crotch belt 100 upward until the downward movement of the first end 101 of the crotch belt 100 is blocked by the first end blocking member 101A. Furthermore, when the user passes the second end 102 of the crotch belt 100 through different second holes 13, the distances between the different second holes 13 and the first hole 15 are different, and therefore the length of the portion between the second end 102 of the crotch belt 100 and the second hole 13 (i.e., the portion of the crotch belt 100 exposed to the upper surface 11A of the seat portion 10) changes, and the length of the usage session of the crotch belt 100 changes accordingly. This allows the length of the used portion of the crotch belt 100 to be adjusted, and also allows, for example, the height of the buckle 20 (see FIG. 22 ) located at the second end 102 of the crotch belt 100 relative to the seat portion 10 to be adjusted, making the crotch belt 100 suitable for children of different physiques. On the other hand, because the different second holes 13 are located at different positions in the front-to-rear direction of the seat portion 10, the crotch belts 100 passing through the different second holes 13 are located at different positions in the front-to-rear direction of the seat portion 10, making the crotch belt 100 suitable for children of different physiques.

[0161] 22A to 27, when the second end 102 of the crotch belt 100 passes through the second hole 13 farther from the first hole 15 and is exposed on the upper surface 11A of the seat 10, the distance between the second hole 13 farther from the first hole 15 and the first hole 15 is relatively long. Therefore, when the crotch belt 100 is fastened, the length of the portion of the crotch belt 100 between the second end 102 and the second hole 13 becomes relatively short. In other words, the length of the portion of the crotch belt 100 exposed on the upper surface 11A of the seat 10 becomes relatively short. This makes it possible to relatively lower the height of the buckle 20 (see FIG. 22) disposed at the second end 102 of the crotch belt 100 relative to the seat 10. At the same time, the crotch belt 100 passing through the second hole 13 farther from the first hole 15 is positioned closer to the backrest 30 in the front-to-rear direction of the seat 10, making it suitable for children with small builds.

[0162] When the second end 102 of the crotch belt 100 passes through the second hole 13 adjacent to the first hole 15 and is exposed on the upper surface 11A of the seat portion 10, the distance between the second hole 13 adjacent to the first hole 15 and the first hole 15 is relatively short. Therefore, when the crotch belt 100 is fastened, the length of the portion of the crotch belt 100 between the second end 102 and the second hole 13 becomes relatively long. In other words, the portion of the crotch belt 100 exposed on the upper surface 11A of the seat portion 10 becomes relatively long, and the height of the buckle 20 (see FIG. 22 ) arranged at the second end 102 of the crotch belt 100 relative to the seat portion 10 can be made relatively high. On the other hand, the crotch belt 100 passing through the second hole 13 adjacent to the first hole 15 is located farther from the backrest portion 30 in the front-to-rear direction of the seat portion 10, and is therefore suitable for children with a larger build.

[0163] Of course, the plurality of second holes 13 may include two or more second holes 13 to meet different practical requirements.

[0164] In the second embodiment of the crotch belt length adjusting device 100A, a flat, wide belt may be used as the crotch belt 100. The first hole 15 and the plurality of second holes 13 may cooperate to form an elongated hole so that the crotch belt 100 can pass through these holes more smoothly.

[0165] The first hole 15 and the plurality of second holes 13 may have the same shape and size.

[0166] In one embodiment, as shown in Figures 24, 25 and 28, the extension directions E of the first holes 15 and the multiple second holes 13 are parallel to each other and parallel to the width direction W of the sheet portion 10.

[0167] The first hole 15 and the plurality of second holes 13 may be arranged at intervals along the front-rear direction perpendicular to the width direction W of the seat portion 10.

[0168] According to this configuration, when the crotch belt 100 moves from one second hole 13 to the other second hole 13, the separation distance between the two second holes 13 becomes equal to the change in length of the used portion of the crotch belt 100 at two different adjustment positions, i.e., the adjustment stroke of the crotch belt 100 between the two adjustment positions of the crotch belt 100.

[0169] Furthermore, with this configuration, the first hole 15 is closer to the front end of the seat portion 10 (i.e., the end of the seat portion 10 farther from the backrest portion 30) than the plurality of second holes 13, and furthermore, the first end 101 of the crotch belt 100 is exposed on the upper surface 11A of the seat portion 10 at a position closer to the front end of the seat portion 10 than the first end 101 is blocked by the first hole 15 and the second end 102 passes through one of the second holes 13 and is exposed on the upper surface 11A of the seat portion 10. Therefore, a hidden section 1001 (described later) of the crotch belt 100 between the first hole 15 and the second hole 13 is positioned below the lower surface 11B of the seat portion 10 and is arranged along the front-to-rear direction of the seat portion 10, and the arrangement direction is offset from the direction of stress that tightens the crotch belt 100 (generally tightens upward) to restrain an infant, so that the user can operate the crotch belt 100 more easily.

[0170] 22A to 23, in order to make it easier for the user to move the crotch belt 100 from one second hole 13 to the other second hole 13, the plurality of second holes 13 can be connected to one another via connecting holes 14 formed through the seat portion 10. Therefore, the user can easily and quickly adjust the position by simply moving the crotch belt 100 between the plurality of second holes 13 via the connecting holes 14.

[0171] As shown in Figures 22A to 23, the connection holes 14 can also be arranged as elongated holes, and extend in a direction intersecting the extension direction E of the second holes 13 (see Figures 24 and 25). In one embodiment, the connection holes 14 extend in a direction perpendicular to the extension direction E of the second holes 13. This prevents the crotch belt 100 from accidentally sliding from one second hole 13 to the other second hole 13 via the connection holes 14.

[0172] Of course, the present application is not limited to this. The first holes 15 and the plurality of second holes 13 may be formed as holes of other shapes. Furthermore, the extending directions of the first holes 15 and the plurality of second holes 13 do not have to be parallel to each other or to the width direction W of the sheet portion 10. Furthermore, the first holes 15 and the plurality of second holes 13 may be formed in the sheet portion 10 in other arrangements.

[0173] In the embodiment shown in FIGS. 27 and 28, the connection holes 14 do not have to be arranged between the plurality of second holes 13.

[0174] In one embodiment, when it is necessary to attach or detach the crotch belt 100 to or from the seat portion 10 or to adjust the length of the usage session of the crotch belt 100, the first end 101 is moved away from the first end inhibition member 101A so that the first end 101 can freely pass through the first hole 15 and the second hole 13, and the crotch belt 100 is moved from one second hole 13 to the other second hole 13, and after the first end 101 of the crotch belt 100A passes through the other second hole 13 and passes from the lower surface 11B of the seat portion 10 through the first hole 15 to reach the upper surface 11A, the first end 101 and the first end inhibition member 101A are connected.

[0175] In addition, in order to avoid the inconvenience caused by the first end 101 and the first end inhibition member 101A being connected at a distance, the first end inhibition member 101A may be positioned so that the sum of its thickness and the thickness of the crotch belt 100 is equal to, and preferably smaller than, the width of the first hole 15 and the second hole 13. When the total thickness of the first end inhibition member 101A and the crotch belt 100 is equal to, or preferably smaller than, the width of the first hole 15 and the second hole 13, the first end inhibition member 101A arranged together with the crotch belt 100 can pass through the first hole 15 in a direction in which the end surface in the thickness direction coincides with the first hole 15, and can pass through the second hole 13 in a direction in which the end surface in the thickness direction coincides with the second hole 13, and the first end 101 of the crotch belt 100 provided with the first end inhibition member 101A can be selectively obstructed by the first hole 15 or can pass through the first hole 15 and the second hole 13 without moving away from the first end inhibition member 101A, allowing adjustment for position adjustment.

[0176] In addition, the first end inhibition member 101A in the second embodiment of the crotch belt length adjustment device 100A can be arranged so that its thickness is the sum of its thickness and the thickness of the crotch belt 100, and preferably, the widths of the first hole 15 and the second hole 13 can also be applied to the first end inhibition member 101A and / or the second end inhibition member 102A, and the first end 101 of the crotch belt 100 provided with the first end inhibition member 101A in the first embodiment can be selectively inhibited by or pass through the first hole 15, and / or the second end 102 of the crotch belt 100 provided with the second end inhibition member 102A in the first embodiment can be selectively inhibited by or pass through the second hole 13 and the connecting hole 14.

[0177] In addition, the crotch belt 100 of the crotch belt length adjustment device 100A of the present application can also be said to have a hidden section 1001 (the part of the crotch belt 100 that is hidden below the seat part 10) located below the lower surface 11B of the seat part 10, and an exposed section 1002 (the part of the crotch belt 100 that is exposed above the seat part 10) located above the upper surface 11A of the seat part 10.

[0178] Specifically, the crotch belt length adjustment device 100A of the present application is a crotch belt 100 having a plurality of second holes 13 formed to penetrate the seat portion 10, and the crotch belt 100 is arranged to pass through the second holes 13, and has a hidden section 1001 located below the lower surface 11B of the seat portion 10 and an exposed section 1002 located above the upper surface 11A of the seat portion 10.

[0179] The crotch belt 100 has a first end 101 and a second end 102 . When the first end 101 of the crotch belt 100 is connected to the seat portion 10, the distance between the first end 101 of the crotch belt 100 and different second holes 13 changes as the crotch belt 100 passes through different second holes 13. (The usable length of the hidden section 1001 is the length of the hidden section 1001 when the crotch belt 100 is fastened, and this length corresponds to the distance between the first end 101 of the crotch belt 100 and the second hole 13 through which the crotch belt 100 is passed along the lower surface 11B of the seat portion 10.) Accordingly, the usable length of the exposed section 1002 also changes. (The usable length of the exposed section 1002 is the length of the exposed section 1002 when the crotch belt 100 is fastened, and this length corresponds to the distance between the second end 102 of the crotch belt 100 and the second hole 13 through which the crotch belt 100 is passed.)

[0180] In embodiments in which the safety belt 200 of the child carrier 1 is provided with a connection clap 40 , the exposed section 1002 of the crotch belt 100 may be provided with a buckle 20 engageable with the connection clap 40 .

[0181] When the crotch belt 100 passes through the second hole 13 adjacent to the first end 101, the distance between the second hole 13 adjacent to the first end 101 and the first end 101 is relatively short. Therefore, when the crotch belt 100 is fastened, the usable length of the hidden section 1001 becomes relatively short, and correspondingly, the usable length of the exposed section 1002 becomes relatively long. Therefore, the height of the buckle 20 arranged in the exposed section 1002 of the crotch belt 100 relative to the seat portion 10 can be made relatively high, which is suitable for children with large builds.

[0182] When the crotch belt 100 passes through the second hole 13 farther from the first end 101, the distance between the second hole 13 farther from the first end 101 and the first end 101 is relatively long. Therefore, when the crotch belt 100 is fastened, the usable length of the hidden section 1001 becomes relatively long, and correspondingly, the usable length of the exposed section 1002 becomes relatively short. This allows the height of the buckle 20 arranged in the exposed section 1002 of the crotch belt 100 relative to the seat portion 10 to be relatively low, making it suitable for children.

[0183] In one embodiment, the first end 101 of the crotch belt 100 may be the end of the hidden section 1001 and connected to the lower surface 11B of the seat portion 10 of the child carrier, and the second end 102 may be the end of the exposed section 1002.

[0184] 22A and 22B, the first end 101 may extend from the end of the hidden section 1001, and the second end 102 may be the end of the exposed section 1002. The crotch belt length adjustment device 100A further has a first hole 15 formed through the seat portion 10, and the first end 101 of the crotch belt 100 is exposed from the lower surface 11B of the seat portion 10 to the upper surface 11A of the seat portion 10 through the first hole 15.

[0185] A first end inhibition member 101A may be provided on a portion of the first end 101 exposed on the upper surface 11A. The same applies to the first end inhibition member 101A. For example, the first end inhibition member 101A may have a length and width greater than the width of the first hole 15 so that it cannot pass through the first hole 15 along the normal direction of the plane formed by the edge in the length direction and the edge in the width direction.

[0186] Furthermore, the first end inhibition member 101A is positioned so that the sum of its thickness and the thickness of the crotch belt 100 is greater than, or the same as, or smaller than the width of the first hole 15 including the second hole 13, and the first end 101 of the crotch belt 100 provided with the first end inhibition member 101A is selectively obstructed by the first hole 15 or can pass through the first hole 15 and the second hole 13 without moving away from the first end inhibition member 101A.

[0187] The arrangement of the first holes 15 and the second holes 13 may be the same as above.

[0188] For example, the first hole 15 and the plurality of second holes 13 may all be elongated holes, and the extending directions thereof are parallel to each other and parallel to the width direction W of the sheet portion 10.

[0189] In another example, the plurality of second holes 13 may be arranged at intervals along a direction perpendicular to the width direction W of the sheet portion 10.

[0190] In another example, the second holes 13 may be connected to one another via connecting holes 14 formed through the sheet portion 10. The connecting holes 14 may also be elongated holes extending in a direction perpendicular to the direction in which the second holes 13 extend. Waist belt distance adjustment device

[0191] The child carrier 1 also generally has two safety belts, each of which is divided into a shoulder belt and a waist belt. Referring to Figures 22A and 22B, when the lower end of the safety belt 200 is fixed to the seat part 10 of the child carrier 1, the upper part of the safety belt 200 is the shoulder belt, and the lower part of the safety belt 200 is the waist belt.

[0192] In addition, the distance between the lower parts (waist belts) of the two safety belts 200 must also be designed in an adjustable manner suitable for children of different physiques, particularly premature babies.

[0193] 22A and 22B, a buckle 20 is provided at the second end 102 of the crotch belt 100, and a connecting clap 40 is disposed between the first end 201 and the second end 202 of the safety belt 200 (see FIG. 22B). When the connecting clap 40 and the buckle 20 engage with each other, the second end 102 of the crotch belt 100 is connected to the safety belt 200. Here, as shown in FIG. 22B, the portion between the second end 202 of the safety belt 200 and the connecting clap 40 constitutes a waist belt.

[0194] Furthermore, the waist belt distance adjusting device 200A according to the present invention can also be suitably used in cases where a waist belt is separately arranged instead of using a part of the safety belt 200 as a waist belt.

[0195] 22A to 29 show a child carrier 1 that employs a waist belt distance adjusting device 200A according to the present application. Here, the child carrier 1 includes a seat portion 10 and a backrest portion 30 that is inclined relative to the seat portion 10.

[0196] The waist belt distance adjusting device 200A according to the present application includes two safety belts 200 each having a first end 201 and a second end 202 (see FIGS. 22A and 22B).

[0197] The first end 201 of the safety belt 200 may be connected to the backrest portion 30 of the child carrier 1 in various ways. For example, the backrest portion 30 may be provided with a fixing structure such as a hanging hook, a hanging ring, or a hole, and the first end 201 of the safety belt 200 may be connected to this fixing structure to prevent the first end 201 from coming off the backrest portion 30.

[0198] In one embodiment, in order to make the usage length of the safety belt 200 adjustable, a fixed opening (shown in Figures 22A and 22B) is provided in the backrest portion 30, and a first end portion 201 of the safety belt 200 passes through the fixed opening in the backrest portion 30 from the front surface of the backrest portion 30 to the rear surface of the backrest portion 30 and is connected to an adjustment belt (not shown), and by adjusting the length of the adjustment belt, the usage length of the safety belt 200 exposed at the front surface of the backrest portion 30 can be adjusted.

[0199] To adjust the safety belt 200, the waist belt distance adjustment device 200A of the present application further includes at least one set (shown as two sets) of waist belt adjustment slots, as shown in Figures 22A to 29, and each set of waist belt adjustment slots includes a plurality (two) of waist belt adjustment slots 16, which are formed through the seat portion 10.

[0200] 22A and 22B, the second ends 202 of the two safety belts 200 each pass through one of a set of waistbelt adjustment slots 16 extending from the upper surface 11A of the seat 10 to the lower surface 11B of the seat 10, and a waistbelt obstructing member 203 is provided on a portion of the second end 202 of the safety belt 200 exposed on the lower surface 11B. The waistbelt obstructing member 203 has a length and width greater than the width of the waistbelt adjustment slot 16, and is thus positioned so as not to pass through the waistbelt adjustment slot 16 in the normal direction to a plane formed by the longitudinal ends and lateral ends of the waistbelt adjustment slot 16, and the waistbelt obstructing member 203 can be obstructed by the waistbelt adjustment slot 16 on the lower surface 11B of the seat 10.

[0201] In one embodiment, the waistbelt inhibiting member 203 may be arranged so that the sum of its thickness and the thickness of the crotch belt 100 is greater than, or the same as, or smaller than the width of the waistbelt adjustment slot 16. When the sum of the thicknesses of the waistbelt inhibiting member 203 and the safety belt 200 is greater than the width of the waistbelt adjustment slot 16, the waistbelt inhibiting member 203 arranged together with the safety belt 200 cannot pass through the waistbelt adjustment slot 16 at any angle because the overall dimensions (length, width, thickness) of the waistbelt inhibiting member 203 and the safety belt 200 are greater than the width of the waistbelt adjustment slot 16, and the second end 202 of the safety belt 200 can pass through the waistbelt adjustment slot 16 away from the waistbelt inhibiting member 203. When the sum of the thicknesses of the waistbelt inhibiting member 203 and the safety belt 200 is the same as the width of the waistbelt adjustment slot 16, preferably smaller than the width of the waistbelt adjustment slot 16, the waistbelt inhibiting member 203 arranged together with the safety belt 200 can pass through the waistbelt adjustment slot 16 along the thickness direction of the waistbelt adjustment slot 16, so that the safety belt 200 provided with the waistbelt inhibiting member 203 can be selectively inhibited by or pass through the waistbelt adjustment slot 16, and the safety belt 200 provided with the waistbelt inhibiting member 203 can be selectively inhibited by or pass through the waistbelt adjustment slot 16 without separating the waistbelt inhibiting member 203 from the waistbelt inhibiting member 203, which is useful for connecting and disconnecting the second end 202 of the waistbelt 200 to and from the seat portion 10.

[0202] In one embodiment, the waistbelt inhibiting member 203 may employ a frame buckle with an intermediate crossbar and a multi-layered folded structure that is larger than the waistbelt adjustment slot 16 .

[0203] In addition, the waist belt inhibiting member 203 located below the seat portion 10 may fall under its own weight, causing the second end 202 of the safety belt 200 to fall along with it, increasing the length of the portion of the safety belt 200 that falls below the seat portion 10, which may affect the user's use of the safety belt 200.

[0204] Here, the waist belt distance adjusting device 200A has a waist belt limiting structure, and the waist belt limiting structure is configured to limit the movement of the waist belt inhibiting member 203 relative to the lower surface 11B of the seat portion 10.

[0205] 24 and 25, the waist belt restricting structure may be an obstructing member engaging structure 18 provided on the lower surface 11B of the seat unit 10. In the embodiment shown in FIGS. 24 and 25, the obstructing member engaging structure 18 is an elastic finger-shaped protrusion around the waist belt adjustment slot 16, and restricts movement of the waist belt obstructing member 203 relative to the lower surface 11B of the seat unit 10 by engaging with edges (for example, two opposing edges) of the waist belt obstructing member 203. In addition, an engagement structure avoidance hole 18A is formed in the seat unit 10 at a position corresponding to the obstructing member engaging structure 18, penetrating the seat unit 10, to provide a space for elastically deforming the elastic fingers of the obstructing member engaging structure 18.

[0206] Of course, the obstructing member engaging structure 18 may have other shapes and structures as long as it can engage with the waist belt obstructing member 203 and restrict movement of the waist belt obstructing member 203 relative to the lower surface 11B of the seat portion 10.

[0207] In another embodiment, the waistbelt inhibiting member 203 has at least one waistbelt inhibiting member through-slot 203A (the waistbelt inhibiting member 203 shown in Figures 24 and 25 has two waistbelt inhibiting member through-slots 203A). The waistbelt restricting structure can be formed by the second end 202 of the safety belt 200 passing from the upper surface 11A of the seat portion 10 through the waistbelt adjustment slot 16 and the waistbelt inhibiting member 203 in sequence, then passing reversibly through the waistbelt adjustment slot 16 and returning above the upper surface 11A of the seat portion 10, and being connected to another portion of the safety belt 200 above the upper surface 11A of the seat portion 10.

[0208] 29, the waistbelt restricting structure may be formed as a half bow knot 204 having one wing and being larger than the waistbelt adjustment slot 16. The free end of the half bow knot 204 is positioned to abut against the upper surface 11A of the seat portion 10, thereby restricting movement of the waistbelt inhibiting member 203 relative to the lower surface 11B of the seat portion 10.

[0209] Of course, the waist belt restricting structure according to the present application may take other forms as long as it can restrict the movement of the waist belt inhibiting member 203 relative to the lower surface 11B of the seat portion 10.

[0210] 22A to 29, the waist belt distance adjustment device 200A has two sets of waist belt adjustment slots, and each set of waist belt adjustment slots has two waist belt adjustment slots 16. Also, FIGS. 22A and 22B show that the second ends 202 of the two safety belts 200 each pass through one waist belt adjustment slot 16 of one set of waist belt adjustment slots.

[0211] However, the present application is not limited to this.

[0212] The waist belt distance adjusting device 200A may have only one set of waist belt adjustment slots, or may have two or more sets of waist belt adjustment slots.

[0213] When the waist belt distance adjustment device 200A has only one set of waist belt adjustment slots, the second end 202 of only one of the two safety belts 200 may pass through a different waist belt adjustment slot 16 of the set of waist belt adjustment slots. The second end 202 of the other safety belt 200 may be movably or fixedly connected to the seat unit 10 in another manner. For example, a fixing structure such as a hanging hook, hanging ring, or hole may be provided on the seat unit 10, and the second end 202 of the other safety belt 200 may be connected to this fixing structure to prevent the second end 202 of the other safety belt 200 from coming off the seat unit 10. In this case, the second end 202 of one of the two safety belts 200 can pass through a different waist belt adjustment slot 16 of the set of waist belt adjustment slots, so that the distance between the two safety belts 200 can also be adjusted.

[0214] Also, if each set of waist belt adjustment slots includes three or more waist belt adjustment slots 16, the distance adjustment range between the safety belts 200 may be increased.

[0215] 22A to 29, two sets of waist belt adjustment slots can be arranged on both sides of the seat portion 10 along the width direction W of the child carrier 1, that is, two safety belts 200 can be arranged symmetrically, and a child secured by the safety belts 200 feels more comfortable. Of course, the two sets of waist belt adjustment slots can also be arranged at other positions on the seat portion 10.

[0216] In the waist belt distance adjustment device 200A according to the present application, a flat, wide belt may be adopted as the safety belt 200. In response to this, the waist belt adjustment slot 16 may be formed as an elongated hole so that the safety belt 200 can pass through the waist belt adjustment slot 16 more smoothly.

[0217] In one embodiment, as shown in FIGS. 22A to 29, the extension directions of the plurality of waist belt adjustment slots 16 are parallel to each other and perpendicular to the width direction W of the seat portion 10.

[0218] The plurality of waist belt adjustment slots 16 are arranged at intervals along the width direction W of the seat portion 10.

[0219] In order to make it easier for the user to move the safety belt 200 from one waist belt adjustment slot 16 to the other waist belt adjustment slot 16, in the embodiment shown in Figures 22A to 29, the multiple waist belt adjustment slots 16 may be connected to each other via waist belt connection slots 17 formed through the seat portion 10. This allows the user to easily and quickly adjust the position adjustment by simply moving the safety belt 200 between the multiple waist belt adjustment slots 16 via the waist belt connection slots 17.

[0220] 22A to 29, the waist belt connection slot 17 is also formed as an elongated hole and extends in a direction intersecting the extension direction of the waist belt adjustment slot 16. In one embodiment, the waist belt connection slot 17 is arranged to extend in a direction perpendicular to the extension direction of the waist belt adjustment slot 16. This configuration makes it possible to prevent the safety belt 200 from accidentally sliding from one waist belt adjustment slot 16 to the other waist belt adjustment slot 16 via the waist belt connection slot 17.

[0221] Of course, the present application is not limited to this. The multiple waist belt adjustment slots 16 and the waist belt connection slots 17 may be holes of other shapes. Furthermore, the extension directions of the multiple waist belt adjustment slots 16 do not have to be parallel to each other or perpendicular to the width direction W of the seat portion 10. Furthermore, multiple waist belt adjustment slots 16 may be formed in the seat portion 10.

[0222] The waist belt distance adjustment device 200A of the present application also allows adjustment of the safety belt 200 at different adjustment positions, and conversion between the multiple adjustment positions is realized using multiple waist belt adjustment slots 16. The safety belt 200 can pass through the different waist belt adjustment slots 16 in various ways, thereby changing the distance between the two safety belts 200, i.e., adjusting the position.

[0223] That is, in one embodiment in which multiple waist belt adjustment slots 16 are connected via waist belt connection slots 17, as shown in Figures 22A to 29, the user can move the waist belt 200 between the multiple waist belt adjustment slots 16 via the waist belt connection slots 17 to adjust the waist belt inhibiting member 203 arranged at the second end 202 of the waist belt 200 from one inhibiting position to the other inhibiting position on the lower surface 11B of the seat portion 10, and then place it at the other inhibiting position via the waist belt regulating structure, thereby making it possible to perform adjustments for position adjustment easily and quickly.

[0224] In an embodiment where the waistbelt connection slot 17 is not disposed between the waistbelt adjustment slots 16, the way in which the safety belt 200 passes through a different waistbelt adjustment slot 16 is as follows: the second end 202 of the safety belt 200, which is positioned below the lower surface 11B of the seat portion 10, moves away from the waistbelt inhibiting member 203, then passes through the current waistbelt adjustment slot 16 and retreats above the upper surface 11A of the seat portion 10; then, the second end 202 of the safety belt 200 passes through another waistbelt adjustment slot 16 from the upper surface 11A of the seat portion 10 and reaches below the lower surface 11B of the seat portion 10; and finally connects with the waistbelt inhibiting member 203, and positions the waistbelt inhibiting member 203 at a corresponding inhibiting position on the lower surface 11B of the seat portion 10 via the waistbelt limiting structure, thereby realizing position adjustment.

[0225] Furthermore, when the safety belt 200 passes through different waist belt adjustment slots 16, the waist belt inhibiting member 203 is configured so that the sum of the thicknesses of the waist belt inhibiting member 203 and the safety belt 200 is the same as the width of the waist belt adjustment slot 16, and preferably smaller than the width of the waist belt adjustment slot 16. In this case, the waist belt inhibiting member 203 arranged together with the safety belt 200 can be pulled back from below the lower surface 11B of the seat portion 10 to above the upper surface 11A in a direction in which the thickness direction end surfaces of the waist belt inhibiting member 203 and the seat portion 10 coincide with the waist belt adjustment slot, and then the waist belt inhibiting member 203 arranged together with the safety belt 200 can pass through another waist belt adjustment slot 16 from the upper surface 11A of the seat portion 10 and reach below the surface 11B of the seat portion 10 in a direction in which the thickness direction end surfaces of the waist belt inhibiting member 203 and the seat portion 10 coincide with the waist belt adjustment slot, and finally, the waist belt inhibiting member 203 is positioned at a corresponding obstructing position on the lower surface 11B of the seat portion 10 via the waist belt limiting structure, thereby realizing adjustment for position adjustment.

[0226] 22A and 22B, when the two safety belts 200 pass through the two waist belt adjustment slots 16 adjacent to the center of the seat unit 10, the two waist belt adjustment slots 16 corresponding to the second ends 202 of the two safety belts 200 are respectively fixed to the waist belt adjustment slots 16 adjacent to the center of the seat unit 10. At this time, the waist belt inhibiting member 203 arranged at the second ends 202 of the safety belts 200 can be positioned at a first inhibiting position on the lower surface 11B of the seat unit 10 via the waist belt limiting structure. In addition, since the distance between the two waist belt adjustment slots 16 is relatively short, the distance between the two portions of the two safety belts 200 exposed on the upper surface 11A of the seat unit 10 is also relatively short, making it suitable for small children.

[0227] When the two safety belts 200 pass through the two waist belt adjustment slots 16 that are far from the center of the seat 10, respectively, that is, the two waist belt adjustment slots 16 that correspond to the second ends 202 of the two safety belts 200 are respectively fixed to the two waist belt adjustment slots 16 that are far from the center of the seat 10. At this time, the waist belt inhibiting members 203 arranged at the second ends 202 of the safety belts 200 can be positioned at second shielding positions on the lower surface 11B of the seat 10 via the waist belt limiting structure. Because the distance between the two waist belt adjustment slots 16 is relatively long, the distance between the two portions of the two safety belts 200 exposed on the upper surface 11A of the seat 10 is also relatively long, which can accommodate larger children.

[0228] Since the features of the present application can be implemented in various ways without departing from the features of the present application, the above embodiments are not particularly limited, but are indicated by the scope of the claims, and are intended to include all modifications within the meaning and scope equivalent to the scope of the claims.
