Description

[Technical Field]

[0001] The present invention relates to a baby carrier. [Background technology]

[0002] Baby carriers are devices that safely support an infant and reduce the burden on the user when carrying an infant while moving or performing some work. Baby carriers are capable of supporting the infant's weight and posture by using a seat on which the infant's buttocks rest and a waist belt that secures the seat.

[0003] Such baby carriers have a tightening unit (corresponding to a length adjusting means) for adjusting the length of the waist belt when the user wears it. The waist belt is composed of a first waist belt portion and a second waist belt portion, and the tightening unit adjusts the length of the waist belt by winding in an adjuster a wire connecting the first waist belt portion and the second waist belt portion. The tightening unit is positioned so that it is in the center of the back when the baby carrier is worn (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 2] International Publication No. WO2020 / 122347 Summary of the Invention [Problem to be solved by the invention]

[0005] The baby carrier in Patent Document 1 has a problem in that when the user wears it, the wire that adjusts the length of the waist belt is located almost in the center of the back, so even if the waist belt is tightened by operating the adjustment tool, a gap is likely to form between the seat and the user's abdomen near the connection point between the seat and the waist belt, making it impossible to bring the seat into close contact with the abdomen, making the seat prone to wobbling and unable to stably support the infant. If the waist belt is tightened too much to prevent this gap from forming, the seat may press against the abdomen, causing abdominal pain.

[0006] When using a baby carrier, the user may place the seat in the center of the abdomen, or may hold the baby with the seat shifted to the left or right from the center of the abdomen, allowing the free arm to do some work. If the seat is shifted from the center of the abdomen, the tightening unit will also be shifted, making it difficult to place the seat tightly against the abdomen and preventing the baby from being supported stably.

[0007] In addition, the adjuster for adjusting the length of the waist belt is located in one place on the right side. For example, if the user is left-handed, there is the problem that adjusting the length (tightening) of the waist belt using the adjuster on the right side can be cumbersome.

[0008] Therefore, the present invention has been made to solve at least one of these problems, and aims to realize a baby carrier that can stably support an infant while reducing the burden on the user, and that allows the length of the waist belt to be easily adjusted (tightness adjustment). [Means for solving the problem]

[0009] [1] The baby carrier of the present invention comprises a seat portion having a seat surface on which an infant's buttocks are placed, a first waist belt portion extending leftward from the seat portion when worn by a user, and a second waist belt portion extending rightward, a first length adjustment means arranged near the seat portion of the first waist belt portion for adjusting the length of the first waist belt portion, and a second length adjustment means arranged near the seat portion of the second waist belt portion for adjusting the length of the second waist belt portion, wherein the first length adjustment means has a first adjustment tool that can be operated to adjust the length, and the second length adjustment means has a second adjustment tool that can be operated to adjust the length, and the first adjustment tool and the second adjustment tool are each configured to be able to independently adjust the lengths of the first waist belt portion and the second waist belt portion.

[0010] [2] In the baby carrier of the present invention, it is preferable that the first length adjustment means has a first movable part at one end of the first length adjustment region of the first waist belt part, the first adjustment device is fixed to the other end, and a connecting member between the first movable part and the first adjustment device is provided to adjust the length of the first length adjustment region, and the second length adjustment means has a second movable part at one end of the second length adjustment region of the second waist belt part, the second adjustment device is fixed to the other end, and a connecting member between the second movable part and the second adjustment device is provided to adjust the length of the second length adjustment region.

[0011] [3] In the baby carrier of the present invention, it is preferable that the first moving part is arranged on the seat side of the first length adjustment area, and the second moving part is arranged on the seat side of the second length adjustment area.

[0012] [4] In the baby carrier of the present invention, it is preferable that the first adjustment device is arranged on the seat side of the first length adjustment area, and the second adjustment device is arranged on the seat side of the second length adjustment area.

[0013] [5] In the baby carrier of the present invention, it is preferable that the connecting member is a wire that spans between the first moving part and the first adjustment device, and between the second moving part and the second adjustment device, the first moving part and the second moving part have wire support parts that support the wire so that it can slide, and the first adjustment device and the second adjustment device are configured to be able to wrap around the wire.

[0014] [6] In the baby carrier of the present invention, it is preferable that the first adjustment device and the second adjustment device have dials that can be grasped and rotated with fingers, and that the first adjustment device and the second adjustment device are configured so that the winding directions of the wire are opposite to each other.

[0015] [7] In the baby carrier of the present invention, it is preferable that the first adjustment device and the second adjustment device are configured so that the wire can be wound in when the dial is pushed in the thickness direction toward the first waist belt portion or the second waist belt portion, and the wire is released from the winding in when the dial is pulled away in the thickness direction from the first waist belt portion or the second waist belt portion. [Effects of the Invention]

[0016] The baby carrier of the present invention described above has first and second length adjustment means for adjusting the lengths of the first and second waist belts extending on either side of the seat on which the infant is placed. The first and second length adjustment means allow the lengths of the first and second waist belts to be adjusted in first and second length adjustment regions, respectively, located near the seat. This configuration allows the first and second waist belts to be tightened in a balanced manner near the connection between the seat and the first and second waist belts, thereby allowing the seat to be closely fitted to the user's abdomen with a suitable tightening force, thereby stably supporting the infant while reducing the user's load. Note that "nearby" refers to a position closer to the connection between the seat and the first and second waist belts.

[0017] Furthermore, the baby carrier of the present invention can simultaneously tighten the seat on both sides in a balanced manner, thereby reducing the feeling of pressure from the seat.

[0018] Furthermore, since the first length adjustment means is provided on the left side and the second adjustment means is provided on the right side when the user wears the baby carrier, even if the user shifts the seat to the left or right, the first and second adjustment devices are located in easy-to-operate positions, making it easy to adjust the length of the waist belt, i.e., the tightness.Also, whether the user is right-handed or left-handed, the tightness can be easily adjusted.

[0019] As described above, the baby carrier of the present invention is capable of stably supporting an infant while reducing the burden on the user, and allows for easy adjustment of the length of the waist belt (adjustment of tightness). [Brief explanation of the drawings]

[Figure 3] 10 is an explanatory diagram illustrating a method for adjusting the length of the first waist belt portion 14. FIG. [Figure 4] FIG. 2 is a partial plan view showing the baby carrier 2 in an unfolded state. DETAILED DESCRIPTION OF THE INVENTION

[0021] Baby carriers 1 and 2 according to the embodiments will be described below with reference to Figures 1 to 4. Note that the figures described below are schematic diagrams in which the scale and shape differ from the actual ones.

[0022] (Baby Carrier 1 Configuration) FIG. 1 is a perspective view showing the schematic configuration of a baby carrier 1. Baby carrier 1 is a baby carrier that can carry an infant while providing stable support. Baby carrier 1 is composed of a seat section 11 with a seat surface 10 on which the infant's buttocks are placed, a waist belt 12 that is wrapped around the waist of the user, a torso support section 13 that is detachable from the tip of seat section 11, and a waist support section 23 to which seat section 11 is attached and that comes into contact with the abdomen. In FIG. 1, the torso support section 13 side (the side in front of the user) is referred to as the front, the opposite side (the side behind the user) is referred to as the rear, and the left side facing the front is referred to as the left side, and the opposite side is referred to as the right side.

[0023] When the user wears the baby carrier 1, the waist belt 12 is composed of a first waist belt portion 14 extending leftward from the seat portion 11 and a second waist belt portion 15 extending rightward. The first waist belt portion 14, the second waist belt portion 15, and the waist support portion 23 are integrated and are referred to separately to explain the left and right configurations. The first waist belt portion 14 and the second waist belt portion 15 are configured so that they can be attached to the user by overlapping their ends on the side opposite the seat portion 11 with a connector 16. A first length adjustment means 17 is located near the left side of the seat portion 11, and a second length adjustment means 18 is located near the right side of the seat portion 11.

[0024] The first length adjustment means 17 has a first adjustment tool 20 for adjusting (shortening) the length of the first waist belt part 14 in a first length adjustment region 19. The second length adjustment means 18 has a second adjustment tool 22 for adjusting (shortening) the length of the second waist belt part 15 in a second length adjustment region 21. The configurations of the waist belt 12, the first length adjustment means 17, and the second length adjustment means 18 will be described in detail with reference to FIG. 2.

[0025] Although not shown in the figures, the seat 11 houses a base inside a fabric bag, and the seat surface 10 on which the infant's buttocks rest is made of a non-slip material to stabilize the infant's posture. The seat 11 is fixed by the fabric bag to the lumbar support section 23 of the waist belt 12, which is the part that comes into close contact with the user's abdomen when worn. The inner surface of the waist belt 12, including the lumbar support section 23, is made of a non-slip and breathable material. Before an infant is placed on the baby carrier 1, the front end of the baby carrier 1 is attached at an angle above the upper end surface of the waist belt 12, and is configured so that it becomes nearly horizontal when an infant is placed on it. This allows for stable support of the infant.

[0026] The torso support section 13 supports the torso of an infant placed on the seat section 11. The torso support section 13 includes a planar support section 30 that supports the torso of the infant and two shoulder straps 31 that can be worn over the user's shoulders. The torso support section 13 is detachably attached to the front end of the seat section 11. For example, a buckle consisting of a plug and a receiving part, or a slide fastener, can be used as an attachment method. The two shoulder straps 31 are equipped with length adjusters 32, such as length-adjustable buckles, for adjusting their length. Although not shown, the two shoulder straps 31 can be worn across the user's back or crossed over to support the infant more stably. The baby carrier 1 can also be used as a hip seat, consisting of the seat section 11 and waist belt 12, without the torso support section 13. Next, the configuration of the waist belt 12 will be described with reference to FIG. 2.

[0027] Fig. 2 is a plan view showing the baby carrier 1 in an unfolded state. Fig. 2 shows the surface that faces outward when the baby carrier 1 is worn by a user, and does not include the torso support part 13. The baby carrier 1 is made up of a seat part 11 and a waist belt 12 that securely supports the seat part 11. The waist belt 12 is made up of a waist support part 23 (see Fig. 1) that secures the seat part 11 and brings it into close contact with the waist of the user when worn by the user, a first waist belt part 14 that extends to the left side, and a second waist belt part 15 that extends to the right side.

[0028] First, the configuration of the first waist belt 14 will be described. The first waist belt 14 includes a first length adjustment means 17 disposed near the left side of the seat 11 for adjusting the length of the first waist belt 14, and a receiving part 35 on one side of a connector 16 that connects the first waist belt 14 and the second waist belt 15 when the baby carrier 1 is worn. The receiving part 35 is a component on one side of the buckle. The first length adjustment means 17 includes a first moving part 37 on the seat 11 side of the first length adjustment area 19, a first adjusting tool 20 fixed to the other end, and a wire 38 serving as a connecting member stretched between the first moving part 37 and the first adjusting tool 20. Note that the connecting member is not limited to the wire 38, and a link mechanism or the like can also be used. The wire 38 can also be pulled manually to fix the wire in a predetermined position.

[0029] The first adjusting tool 20 has a dial 39 that can be rotated clockwise and is fixed to the first waist belt 14 via a fixing cloth member 40. The first moving part 37 has a tubular wire support part 41, through which a wire 38 is inserted. The wire support part 41 supports the wire 38 so that it can slide. The first length adjustment region 19 is a region of the first waist belt 14 whose length is shortened or restored by the first length adjustment means 17. The first length adjustment region 19 is preferably covered with a cloth cover 42. One side of a flat fastener 43 is provided on the back surface of the distal end of the first waist belt 14. The length adjustment (adjustment of tightness) of the first waist belt 14 using the first length adjustment means 17 will be described with reference to FIG. 3.

[0030] Next, the configuration of the second waist belt 15 will be described. The second waist belt 15 has a second length adjustment means 18 that adjusts the length of the second waist belt 15 and is located near the right side of the seat 11, and an insert part 45 on the other side of the connector 16 that connects the first waist belt 14 and the second waist belt 15 when wearing the baby carrier 1. The insert part 45 is a component of a buckle that is attached to the receiving part 35. The second length adjustment means 18 is composed of a second moving part 46 on the seat 11 side of the second length adjustment area 21, a second adjustment tool 22 fixed to the other end, and a wire 38 that serves as a connecting member that spans between the second moving part 46 and the second adjustment tool 22.

[0031] The second adjustment tool 22 has a dial 47 that can be rotated counterclockwise and is fixed to the second waist belt 15 via the fixing cloth material 40. The second movement section 46 has two tubular wire support sections 41, through which the wire 38 is inserted. The wire support sections 41 support the wire 38 so that it can slide. The second length adjustment region 21 is a region of the second waist belt 15 whose length is shortened or restored by the second length adjustment means 18. The second length adjustment region 21 is preferably covered with a cloth cover 42. The other end of the flat fastener 43 is provided on the back surface of the second waist belt 15. Length adjustment (adjustment of tightness) of the second waist belt 15 using the second length adjustment means 18 will be described with reference to FIG. 3.

[0032] (How to wear Baby Carrier 1) The method of wearing the baby carrier 1 will be described with reference to Figures 1 and 2. First, place the waist support part 23 of the waist belt 12 against the abdomen, and overlap the tip of the first waist belt part 14 over the second waist belt part 15 so that the baby carrier 1 is tight enough to prevent it from slipping off, and temporarily secure them with the flat fastener 43. Next, insert part 45 is inserted into the receiving part 35 (see the part indicated by connector 16 in Figure 1). The insert part 45 is attached to the tip of the fixing belt 48, and the other end of the fixing belt 48 is fixed near the second adjustment tool 22 of the second waist belt part 15.

[0033] The insert part 45 is configured to allow the length of the fixing belt 48 to be adjusted, and after attaching the insert part 45 to the receiving part 35, the tightening force can be adjusted appropriately by pulling the end 48a of the fixing belt 48. If sufficient tightening force can be obtained with the surface fastener 43, the fixing belt 48 and the connector 16 can be omitted. However, simply fastening the waist belt 12 with the surface fastener 43 and the fixing belt 48 tends to leave gaps at the connection between the seat 11 and the first and second waist belt parts 14 and 15. Therefore, after wearing the baby carrier 1 around the waist, the waist belt 12 is further tightened using the first adjustment tool 20 and the second adjustment tool 22 to reduce the gaps.

[0034] Figure 3 is an explanatory diagram illustrating a method for adjusting the length of the first waist belt 14. Adjusting the length of the first waist belt 14 means fastening the first waist belt 14 in advance so that the seat 11 does not wobble when the baby carrier 1 is worn and an infant is placed on the seat 11. Figure 3(a) is a diagram before the length is adjusted, and Figure 3(b) is a diagram when the first waist belt 14 is fastened.

[0035] Immediately after putting on the baby carrier 1, the first adjustment device 20 is in a free state, and as shown in Figure 3(a), there is no tension on the wire 38, so it is slack, and there is no change in the first length adjustment region 19, which is part of the first waist-mounted belt part 14, and it is generally in the stretched state it was in before putting on the baby carrier 1. Therefore, after putting on the baby carrier 1, rotate the dial 39 clockwise until the appropriate tightening force is reached so that the seat part 11 does not wobble.

[0036] As shown in FIG. 3(b), when the dial 39 is rotated clockwise, the first adjustment tool 20 winds the wire 38 inside. Because the wire 38 is connected in a ring shape between the wire support part 41 and the first adjustment tool 20, it shortens the distance between the first moving part 37 and the first adjustment tool 20, i.e., the first length adjustment region 19. This makes it possible to shorten the length of the first waist belt part 14 being worn, i.e., the length around the waist belt 12. The first length adjustment region 19 shortens its lengthwise distance by forming vertical wrinkle-like irregularities in the thickness direction across the entire width.

[0037] The first adjusting tool 20 has a mechanism, such as a ratchet mechanism, that allows it to rotate in one direction but not in the opposite direction. Although not shown, the first adjusting tool 20 has a ratchet gear with teeth tilted in one direction, a pawl member that allows the ratchet gear to rotate in one direction but prevents it from rotating in the opposite direction, and a dial 39 that can rotate the ratchet gear. The dial 39 is gripped with the hand (fingers) and rotated.

[0038] Both ends of the wire 38 are fixed to a portion of the ratchet gear. When the dial 39 is rotated in the direction opposite to the inclination of the teeth, the pawl member swings, allowing the ratchet gear to rotate and winding in the wire 38, shortening the distance between the first moving part 37 and the first adjustment tool 20. When the dial 39 is rotated in the reverse direction, the pawl member engages with the teeth of the ratchet gear, preventing reverse rotation. Therefore, even if the dial 39 is released, the pawl member remains engaged with the teeth of the ratchet gear, so the wire 38 slackens, the first length adjustment region 19 does not return to its original length, and the waist belt 12 does not loosen.

[0039] The first adjusting tool 20 is configured to be switchable between a state in which the ratchet gear is rotated, i.e., a state in which the wire 38 can be wound in, and a state in which the wire 38 can be loosened. This switching can be achieved by engaging and disengaging the dial 39 with the ratchet gear. In this example, when the dial 39 is pushed toward the first waist belt part 14, the dial 39 and the ratchet gear engage, allowing the wire 38 to be wound in, and when the dial 39 is pulled away from the first waist belt part 14 in the thickness direction, the winding of the wire 38 is released. In other words, the configuration allows a switching operation in which the dial 39 is pushed in to engage with the ratchet gear and pulled out to disengage from the ratchet gear. Note that if the dial 39 is not operated, the state prior to the operation is maintained.

[0040] The second length adjustment means 18 is oriented differently relative to the seat portion 11 than the first length adjustment means 17, but the configuration itself is the same, so detailed description will be omitted. For example, the first adjustment tool 20 can be replaced with the second adjustment tool 22, the first length adjustment area 19 with the second length adjustment area 21, the first moving part 37 with the second moving part 46, and the dial 39 with the dial 47.

[0041] However, the inclination direction of the teeth of the ratchet gear of the second adjustment tool 22 is opposite to the inclination direction of the teeth of the ratchet gear of the first adjustment tool 20. In other words, by rotating the dial 47 counterclockwise, it is possible to wind in the wire 38 and shorten the length of the second length adjustment region 21. Furthermore, like the first adjustment tool 20, the second adjustment tool 22 is configured to be switchable between a state in which the ratchet gear is rotated, i.e., a state in which the wire 38 can be wound in, and a state in which the wire 38 can be loosened.

[0042] When the baby carrier 1 is worn on the body, the first adjustment device 20 is located on the user's left side, and the second adjustment device 22 is located on the user's right side, with the seat portion 11 sandwiched between them. The first adjustment device 20 is rotatable clockwise, and the second adjustment device 22 is rotatable counterclockwise. This means that when the user tries to fit the seat portion 11 tightly against their abdomen, they can simultaneously rotate the dials 39 and 47 in the same direction on both the left and right sides to fit the seat portion 11 tightly against their abdomen with an appropriate tightening force. Because the first adjustment device 20 and the second adjustment device 22 are located near the seat portion 11, for example, it is possible to easily adjust the tightening force when the seat portion 11 is worn offset to the left or right, or regardless of whether the user is right-handed or left-handed. Furthermore, if the user feels that the tightness is different between the left and right sides, they can adjust the tightness on either the left or right side.

[0043] (Baby Carrier 2 Configuration) In the baby carrier 1 described above, the first length adjustment means 17 and second length adjustment means 18 are arranged such that the first moving section 37 and second moving section 46 are located on the seat 11 side of the first length adjustment area 19 or the second length adjustment area 21, respectively, and the first adjusting tool 20 and second adjusting tool 22 are located at a position away from the seat 11. However, a configuration is also possible in which the first adjusting tool 20 and second adjusting tool 22 are located on the seat 11 side, and the first moving section 37 and second moving section 46 are located at a position away from the seat 11. This will be described as a second example with reference to Figure 4.

[0044] Fig. 4 is a partial plan view showing the unfolded state of baby carrier 2 according to the second example. Fig. 4 shows the surface that faces outward when baby carrier 2 is worn by a user, and does not include torso support section 13. Here, differences from baby carrier 1 will be mainly explained. Parts in common with baby carrier 1 are given the same reference numerals as in Fig. 2. Waist belt 12 is made up of first waist belt section 53 that extends to the left and second waist belt section 54 that extends to the right when worn by a user.

[0045] The first waist belt part 53 has a first length adjustment means 50 for adjusting the length of the first waist belt part 53, which is arranged near the left side of the seat part 11. The first length adjustment means 50 is composed of a first adjustment tool 20 fixed to the seat part 11 side of the first length adjustment region 19, a first moving part 37 arranged at the right end part of the first length adjustment region 19, and a wire 38 as a connecting member stretched between the first moving part 37 and the first adjustment tool 20.

[0046] The first adjusting tool 20 has a dial 39 that can be rotated clockwise, and is fixed to the first waist belt part 14 via a fixing cloth material 40. The first moving part 37 has a cylindrical wire support part 41, through which the wire 38 is inserted. The wire support part 41 supports the wire 38 so that it can slide.

[0047] When the dial 39 is rotated clockwise, the first adjustment tool 20 winds the wire 38 inside. Because the wire 38 is connected in a ring shape between the wire support part 41 and the first adjustment tool 20, the distance between the wire support part 41 and the first adjustment tool 20, i.e., the first length adjustment region 19, is shortened. This makes it possible to shorten the length of the first waist belt part 14 being worn, i.e., the length around the waist belt 12. The first length adjustment region 19 shortens its longitudinal distance by forming vertical wrinkles in the thickness direction across the entire width. As described above, the first length adjustment means 50 has the same function as the first length adjustment means 17 described above, except for the positions of the first adjustment tool 20 and the first moving part 37.

[0048] Like the first length adjustment means 50, the second length adjustment means 51 has the same configuration and function as the previously described second length adjustment means 18, except for the orientation of the first adjustment tool 20 and the first moving part 37. The inclination direction of the teeth of the ratchet gear of the second adjustment tool 22 is opposite to the inclination direction of the teeth of the ratchet gear of the first adjustment tool 20. Therefore, by rotating the dial 47 counterclockwise, the wire 38 can be wound in and the length of the second length adjustment region 21 can be shortened. Furthermore, like the first adjustment tool 20, the second adjustment tool 22 can be switched between a state in which the ratchet gear is rotated, i.e., a state in which the wire 38 can be wound in, and a state in which the wire 38 can be loosened.

[0049] Although not shown, it is preferable that the baby carrier 2 also be provided with a cover 42 (see FIG. 2) on the first length adjustment means 17 and the second length adjustment means 18.

[0050] The baby carrier 1 of the present invention described above comprises a seat 11 with a seat surface 10 on which an infant's buttocks rest, a first waist belt 14 extending leftward from the seat 11 when worn by a user, and a second waist belt 15 extending rightward. The first waist belt 14 has a first length adjustment means 17 arranged near the seat 11 for adjusting the length of the first waist belt 14. The second waist belt 15 has a second length adjustment means 18 arranged near the seat 11 for adjusting the length of the second waist belt 15. The first length adjustment means 17 has a first adjustment tool 20 that can be operated to adjust the length, and the second length adjustment means 18 has a second adjustment tool 22 that can be operated to adjust the length. The first adjustment tool 20 and the second adjustment tool 22 are configured to allow the length adjustment (adjustment of the tightness) of the first waist belt 14 and the second waist belt 15 to be operated independently.

[0051] With the above-described configuration, the baby carrier 1 can tighten the seat 11 in a balanced manner on both sides near the connection between the seat 11 and the first and second waist belts 14, 15. This allows the connection between the seat 11 and the first and second waist belts 14, 15 to be brought into close contact with the user's abdomen, making it possible to stably support the infant. Furthermore, because the baby carrier 1 can tighten the seat 11 in a balanced manner on both sides near the connection between the seat 11 and the first and second waist belts 14, 15, it is possible to reduce the feeling of partial pressure on the abdomen caused by the seat 11.

[0052] Furthermore, the baby carrier 1 is equipped with a first length adjustment means 17 on the left side and a second length adjustment means 18 on the right side. Therefore, even when the user shifts the seat portion 11 to the left or right, the length of the waist belt 12, i.e., the tightness, can be easily adjusted. Alternatively, whether the user is right-handed or left-handed, the tightness can be easily adjusted. Furthermore, it is also possible to adjust the tightness on the right or left side separately.

[0053] As described above, baby carriers 1 and 2 of the present invention are capable of stably supporting an infant while reducing the burden on the user, and allow for easy length adjustment (tightness adjustment) of waist belt 12. Note that baby carrier 2 can also achieve the same effects as baby carrier 1.

[0054] The first waist belt part 14 has a first adjustment tool 20 and a first moving part 37 at both ends in the length direction of the first length adjustment region 19 suspended by a wire 38, which is a connecting member, and the length of the first length adjustment region 19 is adjusted by this wire 38. The second waist belt part 15 has a second adjustment tool 22 and a second moving part 46 at both ends in the length direction of the second length adjustment region 21 suspended by a wire 38, which is a connecting member, and the length of the second length adjustment region 21 is adjusted by this wire 38.

[0055] By adopting such a configuration, the gap between the user's abdomen and the joints between the seat 11 and the first waist belt portion 14 and the second waist belt portion 15 on both sides of the seat 11 is minimized, meaning that the tightness can be adjusted in a balanced manner on the left and right, and the posture of the seat 11 can be stabilized when the infant's buttocks are placed on it.

[0056] In the baby carrier 1, the first moving section 37 is arranged on the seat 11 side of the first length adjustment area 19, and the second moving section 46 is arranged on the seat 11 side of the second length adjustment area 21. With this configuration, it is possible to bring the first length adjustment area 19 and the second length adjustment area 21 closer to the seat 11. As a result, in contrast to the length adjustment area in Patent Document 1 mentioned above, which is arranged on the back of the user, it is possible to bring the seat 11 into close contact with the abdomen of the user in a balanced manner on both sides of the seat 11 at a position closer to the seat 11, and it is possible to maintain a balanced posture of the seat 11 even when the seat 11 is worn shifted left or right.

[0057] In the baby carrier 2, the first adjustment tool 20 is located on the seat 11 side of the first length adjustment area 19, and the second adjustment tool 22 is located on the seat 11 side of the second length adjustment area 21. With this configuration, the first adjustment tool 20 and the second adjustment tool 22, which are the tightening operation parts, are located closer to the seat 11, making it even easier for the user to tighten the seat 11 regardless of the position of the seat 11.

[0058] The first moving section 37 and the second moving section 46 have a wire support section 41 that slidably supports a wire 38 serving as a connecting member, and the first adjusting tool 20 and the second adjusting tool 22 are configured to be able to wind up the wire 38. By winding up the wire 38, the first adjusting tool 20 and the second adjusting tool 22 make it possible to easily adjust the length of the waist belt 12, i.e., the tightness, in the first length adjustment region 19 and the second length adjustment region 21.

[0059] In baby carriers 1, 2, the first adjustment tool 20 and the second adjustment tool 22 have dials 39, 47 that can be grasped and rotated with the fingers. The first adjustment tool 20 and the second adjustment tool 22 are configured so that the winding direction of the wire 38 is opposite to each other. If the winding direction of the first adjustment tool 20 is clockwise, the winding direction of the second adjustment tool 22 is counterclockwise. In this way, when a user puts on the baby carrier 1, 2 and performs a tightening operation, they can rotate the first adjustment tool 20 and the second adjustment tool 22 with both hands in the same ergonomic sense, and can perform the tightening operation without being conscious of left or right.

[0060] The first and second adjusting tools 20 and 22 are configured so that the wire 38 can be wound in when the dials 39, 47 are pressed in the thickness direction toward the first or second waist belt part 14, 15, and the wire 38 is released from the wound state when the dials 39, 47 are pulled away in the thickness direction from the first or second waist belt part 14, 15. This configuration allows the first and second adjusting tools 20 and 22 to be easily switched between two states: a tightening state and a release state. Furthermore, the first and second adjusting tools 20 and 22 can be maintained in either of the two states, the tightening state and the release state, even when released.

[0061] As described above, the baby carriers 1 and 2 of the present invention are capable of stably supporting an infant while reducing the burden on the user, and allow for easy length adjustment (tightness adjustment) of the waist belt 12. [Explanation of symbols]
