Description

Technical Field

[0001] One aspect of the present disclosure relates to a stroller. Background Art

[0002] Conventionally, there is known a stroller having a stroller body and a seat supported by the stroller body (for example, Patent Document 1). In the stroller described in Patent Document 1, the seat is configured to be detachable from the stroller body. In a stroller in which the seat is detachable as described above, in order to fix the seat to the stroller body, a structure is generally adopted in which a plurality of fixing members such as buckle straps provided on the seat surface and backrest of the seat are fixed to the stroller body (frame).

[0003] Prior art literature Patent Literature Patent Document 1: Japanese Patent Application Publication No. 2013-241138 Summary of the invention

[0004] Technical issues In the structure in which the seat cushion is fixed to the stroller body using multiple buckle straps as described above, when installing and removing the seat cushion, all the buckle straps need to be installed and removed, which is time-consuming and laborious. In addition, if buckle straps are provided at multiple locations, it is difficult for the user to accurately grasp and remember the installation position of each buckle strap relative to the stroller body when installing the seat cushion.

[0005] One aspect of the present disclosure aims to provide a baby stroller capable of improving the convenience of attaching and detaching a seat cushion.

[0006] Technical Solution The stroller of one aspect of the present invention comprises a stroller main body having a seat cushion support portion, and a seat cushion supported by the seat cushion support portion, the seat cushion having a seat portion portion and a backrest portion connected to the seat portion portion, the seat cushion support portion having a seat surface support portion supporting the seat portion portion, and a backrest support portion supporting the backrest portion, the seat portion portion having a first surface fastener portion, the first surface fastener portion including one or more surface fasteners arranged on a surface opposite to the seat surface support portion, the backrest portion having a second surface fastener portion, the second surface fastener portion including one or more surface fasteners arranged on a surface opposite to the backrest support portion, the seat surface support portion having a third surface fastener portion including one or more surface fasteners arranged at positions corresponding to the first surface fastener portion, and the backrest support portion having a fourth surface fastener portion including one or more surface fasteners arranged at positions corresponding to the second surface fastener portion.

[0007] In a baby stroller of one aspect of the present disclosure, the seat portion of the seat cushion is fixed to the seat surface support portion of the seat cushion support portion via the first surface hook and loop fastener portion and the third surface hook and loop fastener portion, and the backrest portion of the seat cushion is fixed to the backrest support portion of the seat cushion support portion via the second surface hook and loop fastener portion and the fourth surface hook and loop fastener portion. In this way, by fixing both the seat portion and the backrest portion of the seat cushion to the seat cushion support portion using the surface hook and loop fastener, the seat cushion can be fixed to the seat cushion support portion in a well-balanced and stable manner. In addition, since the number of fixing parts such as buckle belts that are commonly used in the past can be reduced, the disassembly operation of the seat cushion can be simplified. Furthermore, the user can fix the seat cushion to the seat cushion support portion by only pressing the seat portion and the backrest portion of the seat cushion to the position corresponding to the seat cushion support portion, and can disassemble the seat cushion from the seat cushion support portion by only pulling the seat cushion away from the seat cushion support portion (pulling). Therefore, according to the above-mentioned baby stroller, the convenience of loading and unloading operations of the seat cushion can be improved.

[0008] The one or more surface fasteners included in the first surface fastener portion can also be formed into a shape in which the length in the left-right direction is longer than the length in the front-back direction, and the one or more surface fasteners included in the third surface fastener portion can also have a shape corresponding to the one or more surface fasteners included in the first surface fastener portion. Usually, the frame of the baby carriage body is arranged on both sides of the left-right direction of the seat surface support portion of the seat support portion. In contrast, the above-mentioned frame is not arranged in front of the seat surface support portion. Therefore, when the seat portion of the seat cushion is fixed (mounted) on the seat surface support portion, the concern that the seat portion relative to the position of the seat surface support portion is offset in the left-right direction is small, and on the other hand, there is a concern that the seat portion relative to the position of the seat surface support portion is offset in the front-back direction. Assuming that the surface fastener included in the first surface fastener portion or the surface fastener included in the third surface fastener portion is formed into a shape in which the length in the front-back direction is longer than the length in the left-right direction, even if the seat portion of the seat cushion relative to the position of the seat surface support portion is slightly offset in the front-back direction, the first surface fastener portion and the third surface fastener portion will contact and be fixed to each other. In contrast, by forming the surface fasteners included in the first surface fastener portion and the third surface fastener portion into a shape whose length in the left-right direction is longer than that in the front-back direction, when the seat portion portion is offset in the front-back direction relative to the seat surface support portion, the first surface fastener portion and the third surface fastener portion are difficult to contact each other. As a result, it is possible to prevent the seat portion portion from being fixed to the seat surface support portion in a state where it is offset in the front-back direction relative to the seat surface support portion.

[0009] The seat cushion may also have a connecting component provided near the boundary portion where the seat portion and the backrest portion are connected, and the stroller body may also have a frame component connected to the connecting component. According to the above configuration, the seat cushion can be fixed to the seat cushion support portion by using the connecting component while aligning the boundary portion between the seat portion and the backrest portion of the seat cushion at an appropriate position. Thus, for example, by causing the seat portion to swing with the above boundary portion as a swing axis and press against the seat surface support portion, the seat portion can be easily fixed at an appropriate position relative to the seat surface support portion. Similarly, by causing the backrest portion to swing with the above boundary portion as a swing axis and press against the backrest support portion, the backrest portion can be easily fixed at an appropriate position relative to the backrest support portion.

[0010] The second surface fastener portion may also include a plurality of surface fasteners, and the fourth surface fastener portion may also include a plurality of surface fasteners corresponding to the plurality of surface fasteners included in the second surface fastener portion. According to the above configuration, the area of ​​each surface fastener required to fix the backrest relative to the backrest support portion with sufficient strength can be miniaturized. Thus, it is possible to avoid obstructing the air permeability of a specific part of the backrest due to the provision of a large surface fastener, thereby maintaining the comfort of the infant riding in the stroller.

[0011] The second surface fastener portion may also be provided along the edge of the backrest. According to the above configuration, by not providing the surface fastener in the area overlapping the central portion of the backrest, the air permeability of the portion of the backrest that mainly contacts the back of the infant can be ensured, thereby maintaining the comfort of the infant riding in the stroller.

[0012] The second surface fastener portion may also include at least a surface fastener provided along the edge of the backrest portion on the side opposite to the side connected to the seat surface portion. According to the above configuration, the backrest portion is fixed to the backrest support portion at a position as far away from the seat surface portion as possible, so that the backrest portion can be stably supported relative to the backrest support portion.

[0013] The seat cushion support portion may also include a support frame, which is formed along the second portion of the edge of the backrest except for the first portion connected to the seat surface portion, and a suppression component for suppressing deformation of the edge may also be provided on the second portion of the backrest. According to the above configuration, the backrest can be easily and appropriately aligned with the backrest support portion by pressing the backrest against the backrest support portion in such a manner that the second portion of the edge of the backrest is along the support frame. In addition, the suppression component provided on the second portion suppresses the deformation of the second portion, so that the above operation can be easily performed and the support stability of the backrest can be improved.

[0014] The restraining member may also be a covering member that is rolled on the second portion. According to the above configuration, the restraining member can be easily and reliably arranged by using the covering member that is rolled on the second portion. In addition, the visual recognition and appearance of the backrest portion along the portion relative to the support frame are improved by the rolling, so that the user can easily arrange the backrest portion at an appropriate position relative to the seat cushion support portion by using the rolling portion (covering member) as a mark.

[0015] Technical Effects According to one aspect of the present disclosure, it is possible to provide a baby stroller capable of improving the convenience of attaching and detaching a seat cushion. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In this specification, unless otherwise specified, the terms "front", "rear", "left", "right", "up", "down", "front-rear direction", "left-right direction", and "up-down direction" with respect to the baby carriage 1 refer to the "front", "rear", "left", "right", "up", "down", "front-rear direction", "left-right direction", and "up-down direction" based on the infant riding in the unfolded baby carriage 1. When the ground contact surface of the baby carriage 1 is a horizontal plane, the "front-rear direction" is the forward and backward direction of the baby carriage 1 parallel to the ground contact surface. In addition, the "up-down direction" is a direction perpendicular to the front-rear direction and perpendicular to the ground contact surface. In addition, the "left-right direction" is a direction perpendicular to both the front-rear direction and the up-down direction.

[0027] exist Figure 1~Figure 4 , the "front and rear direction" is represented by the X-axis direction, the "left and right direction" is represented by the Y-axis direction, and the "up and down direction" is represented by the Z-axis direction. The negative direction side of the X-axis direction is equivalent to the "front", and the positive direction side of the X-axis direction is equivalent to the "back". In addition, the positive direction of the Y-axis direction is equivalent to the "right", and the negative direction side of the Y-axis direction is equivalent to the "left". In addition, the positive direction of the Z-axis direction is equivalent to the "up", and the negative direction of the Z-axis direction is equivalent to the "down". It should be noted that in the "left and right direction", the side closer to the infant riding in the stroller 1 (the center of the stroller 1 in the left and right direction) is called the inner side, and the side away from the infant is called the outer side.

[0028] like Figure 1 and Figure 2 As shown, the stroller 1 includes a stroller body 2 and a seat 3 attached to the stroller body 2. The stroller body 2 includes a main body frame 10, and a handle 20 connected to the main body frame 10 and a seat support 30. Figure 1 and Figure 2 Each of them is a perspective view showing the baby carriage 1 in the unfolded state. Figure 1 2 is a diagram showing a state where the seat cushion 3 is mounted on the stroller body 2. Figure 2The figure shows a state where the seat cushion 3 is detached from the stroller body 2 .

[0029] The main frame 10 has a pair of front legs 11 respectively arranged on the left and right sides, a pair of rear legs 12 respectively arranged on the left and right sides, and a pair of armrests 13 respectively arranged on the left and right sides. The upper end of each front leg 11 is connected to the front end of the armrest 13 in a rotatable manner, and the armrest 13 is arranged on the side (left or right) corresponding to each front leg 11. Similarly, the upper end of each rear leg 12 is connected to the front end of the armrest 13 in a rotatable manner, and the armrest 13 is arranged on the side (left or right) corresponding to each rear leg 12. The rear end of each armrest 13 is connected to the middle part of the rear leg 12 via a connecting rod member 14 and a rotating bracket 15, and the rear leg 12 is arranged on the side (left or right) corresponding to each armrest 13. A protrusion 14a is provided at the upper end of the connecting rod member 14, and the protrusion 14a is used to connect to a connecting member 101 provided on the side wall portion 80 described later. The protrusion 14 a is formed in a pin shape extending upward in parallel with the link member 14 .

[0030] The handle 20 is connected to the main frame 10 so as to be swingable relative to the main frame 10 constructed as described above. Figure 1 and Figure 2 As shown, the handle 20 is formed in a U shape. Figure 1~Figure 3 In the back-to-back pushing state shown in the figure (i.e., the state in which the operator (protector) holds the handle 20 from the back side of the infant riding in the baby carriage 1 to operate the baby carriage 1), each part at both ends of the handle 20 is connected to the link member 14 on the side (left or right) corresponding to each part in a manner that maintains a state parallel to the link member 14. It should be noted that the handle 20 can also be configured to be able to move along the main frame 10 in a manner that the handle portion of the handle 20 can be moved toward the front of the infant riding in the baby carriage 1. Figure 3 In this case, the operator can hold the handle 20 from the side of the front leg 11 facing the infant to operate the stroller. That is, the stroller 1 can be driven in such a way that the side of the rear leg 12 of the stroller 1 is in front of the traveling direction. In such a face-to-face pushing state, the handle 20 and the link member 14 are not parallel. An operating portion 20a for switching between the unfolded state and the folded state is provided in the central portion of the handle 20. By operating the operating portion 20a, it is possible to switch between a locked state for maintaining the unfolded state or the folded state and an unlocked state for switching between the unfolded state and the folded state.

[0031] As described below, the baby carriage 1 can be changed from the unfolded state (see FIG. Figure 1~Figure 3 ) to the folded state (refer to Figure 4 ).

[0032] In this embodiment, as an example, Figure 1~Figure 3 When the baby carriage 1 in the unfolded state shown in the figure is folded, the handle 20 is temporarily lifted upward and then pushed downward while the operation portion 20a is operated to be in the unlocked state. With the folding operation, the link member 14 and the rotating bracket 15 are separated from the rear legs 12, and the rotating bracket 15 is moved relative to the rear legs 12. Figure 3 and Figure 4 In addition, with this action, the armrest 13 and the seat support frame 31 are rotated in the clockwise direction relative to the link member 14. Figure 3 and Figure 4 It should be noted that since the link member 14 is arranged in parallel with the handle 20, the link member 14 is Figure 3 and Figure 4 The handle 20 is hidden inside.

[0033] like Figure 4 As shown, the baby carriage 1 can be folded by the above-mentioned folding operation. Figure 4 As shown, by placing the baby carriage 1 in the folded state, the size of the baby carriage 1 in the front-rear direction (X-axis direction) can be made smaller than the size of the baby carriage 1 in the unfolded state. It should be noted that to unfold the baby carriage 1 from the folded state, the reverse operation of the folding operation can be performed.

[0034] like Figure 2 As shown, the seat cushion support portion 30 supports the seat cushion 3 in a tiltable manner. The seat cushion support portion 30 includes a seat surface support frame 31 , a backrest support frame 32 , a base cushion 33 , an upper frame 34 , and a connection frame 35 .

[0035] The seat support frame 31 is a frame member located below the buttocks of an infant riding in the baby carriage 1. The backrest support frame 32 is connected to the seat support frame 31 in a swingable manner and is located behind the back of the infant riding in the baby carriage 1. For example, each of the seat support frame 31 and the backrest support frame 32 can be formed of a metal pipe having a U-shape as a whole.

[0036] The base cushion 33 is a fabric member extended over the seat support frame 31 and the backrest support frame 32. The base cushion 33 includes a seat support portion 331 supporting a seat portion 40 of the seat cushion 3 described later and a backrest support portion 332 supporting a backrest portion 50 of the seat cushion 3 described later.

[0037] The upper frame 34 is a U-shaped frame member disposed substantially parallel to the back support frame 32 at a position above the back support frame 32. The connecting frame 35 is a frame member connecting the back support frame 32 and the upper frame 34.

[0038] use Figure 5 and Figure 6 , the seat cushion 3 mounted on the seat cushion support portion 30 will be described. Figure 5 This is a plan view of the seat cushion 3 viewed from the front 4a side (the side where infants sit) in a state where the seat portion 40 and the backrest portion 50 are stretched to be parallel to each other. Figure 6 is viewed from the back side 4b Figure 5 This is a top view of the seat cushion 3 in the same state.

[0039] The seat cushion 3 is made of a cushioning material, for example, and provides a comfortable ride for an infant sitting on the front surface 4a of the seat cushion 3. The seat cushion 3 includes a seat surface 40, a backrest 50, a surrounding portion 60, a cover 70, and a pair of side walls 80.

[0040] The seat surface portion 40 is supported by a seat surface support portion 331 of a base cushion 33 held by the seat surface support frame 31 , and mainly supports the buttocks of an infant riding in the stroller 1 .

[0041] The backrest portion 50 is connected to the seat portion 40 and is located behind the seat portion 40. The backrest portion 50 is supported by the back support portion 332 of the base cushion 33 held by the back support frame 32 and is disposed at a position facing the back of an infant sitting in the stroller 1.

[0042] The seat portion 40 and the backrest portion 50 are connected to each other by, for example, sewing each other. In this case, a connection line L1 formed by a seam is formed between the seat portion 40 and the backrest portion 50. The seat portion 40 and the backrest portion 50 approach each other as the baby carriage 1 is tilted or folded. At this time, the seat portion 40 and the backrest portion 50 swing relative to each other with the connection line L1 as the swing axis.

[0043] The surrounding portion 60 is connected to the edge of the backrest 50 except for the edge (connection line L1) connected to the seat surface 40. The surrounding portion 60 is a portion that covers and protects the upper and side parts of the upper body of the infant riding in the stroller 1. That is, the surrounding portion 60 includes a portion that functions as a headrest to protect the head of the infant. The surrounding portion 60 is, for example, sewn to the backrest 50, and the connection portion between the backrest 50 and the surrounding portion 60 is divided by a substantially U-shaped sewing line.

[0044] The cover portion 70 is a cover-shaped member connected to the edge of the surrounding portion 60 on the side opposite to the side connected to the backrest portion 50 and is provided to cover the back side of the surrounding portion 60. Figure 1As shown, when the seat cushion 3 is mounted on the seat cushion support portion 30, the connection portion between the surrounding portion 60 and the cover portion 70 is along the upper frame 34 (refer to Figure 2 ), and the cover portion 70 is covered in a manner covering the upper frame 34 and the connecting frame 35. Thus, the surrounding portion 60 is stably fixed.

[0045] The pair of side wall portions 80 are arranged on both sides of the seat portion 40 in the left-right direction (Y-axis direction). The side wall portion 80 is bridged between the seat portion 40 and the backrest portion 50. The side wall portion 80 is configured to be Figure 1 ) is not directly supported by the seat cushion support portion 30 and maintains a state of standing approximately vertically relative to the seat surface portion 40.

[0046] A protrusion 85 that extends toward the protrusion 14a of the link member 14 in the expanded state is provided at the end of each side wall portion 80 on the side away from the seat portion 40 and the backrest portion 50. A connecting member 101 connected to the protrusion 14a is provided on the back surface 4b of the protrusion 85. As an example, the connecting member 101 is a buckle belt having a belt portion 101a fixed to the protrusion 85 and a pair of buckles 101b (a pair of buckles that fit together) provided at both ends of the belt portion 101a. By wrapping the belt portion 101a around the side of the protrusion 14a and locking the pair of buckles 101b to each other (i.e., the concave portion and the convex portion to each other), the belt portion 101a can be connected to the protrusion 14a. Figure 1 As shown in FIG. 1 , the connecting member 101 is fixed to the protrusion 14 a . Thus, the standing posture of the side wall portion 80 in the expanded state becomes stable.

[0047] The seat surface 40, the backrest 50, and the surrounding portion 60 that can directly contact the infant riding in the stroller 1 can be formed using, for example, a cushioning fabric. Specific examples of such a fabric include a fabric formed by sandwiching a sponge or other material between two fabrics, a fabric formed by a cushioning fabric itself, and the like. In addition, at least the portion of the side wall 80 that is arranged on the inner side in the left-right direction can also directly contact the infant, and therefore can be formed of a cushioning fabric.

[0048] Next, the details of the mounting structure of the seat cushion 3 relative to the seat cushion support portion 30 will be described. Figure 6As shown, the seat surface portion 40 has a first surface fastener portion 91, which includes one or more surface fasteners provided on the back surface 4b (the surface opposite to the seat surface support portion 331). In this embodiment, the first surface fastener portion 91 includes only one surface fastener 911. The backrest portion 50 has a second surface fastener portion 92, which includes one or more surface fasteners provided on the back surface 4b (the surface opposite to the backrest support portion 332). In this embodiment, the second surface fastener portion 92 includes four surface fasteners 921~924.

[0049] The surface fastener 911 is formed in a laterally long rectangular shape extending in the left-right direction (Y-axis direction) slightly forward of the center portion of the seat surface portion 40 in the front-rear direction (X-axis direction).

[0050] The surface fasteners 921-924 are arranged at a position higher than the central portion in the vertical direction (direction orthogonal to the connection line L1) of the backrest 50 (in the present embodiment, near the upper end of the backrest 50). The surface fasteners 921-924 have substantially the same rectangular shape, and the area of ​​each surface fastener 921-924 is smaller than that of the surface fastener 911.

[0051] The surface fasteners 921 and 924 are arranged at positions symmetrical to each other with respect to the center line along the vertical direction of the backrest 50. The surface fasteners 921 and 924 are arranged along the side edges of the backrest 50 in the left-right direction (Y-axis direction). The surface fasteners 921 and 924 are arranged in a manner that the long side direction of the surface fasteners 921 and 924 is substantially parallel to the side edges of the backrest 50 in the left-right direction (Y-axis direction).

[0052] The surface fasteners 922 and 923 are arranged at positions symmetrical to each other with respect to the center line along the vertical direction of the backrest 50. The surface fasteners 922 and 923 are arranged along the edge 51a of the upper end of the backrest 50. The surface fasteners 922 and 923 are arranged so that the long side direction of the surface fasteners 922 and 923 is substantially parallel to the edge 51a.

[0053] like Figure 2 As shown, the seat surface support portion 331 has a third surface fastener portion 93 at a position corresponding to the first surface fastener portion 91, and the third surface fastener portion 93 includes one or more surface fasteners set to a shape corresponding to the first surface fastener portion 91. In the present embodiment, the third surface fastener portion 93 includes a surface fastener 931 corresponding to the surface fastener 911 included in the first surface fastener portion 91. In the present embodiment, the surface fastener 931 is formed in the same rectangular shape as the surface fastener 911, and is configured at a position overlapping with the surface fastener 911 when the seat surface portion 40 is configured at an appropriate position relative to the seat surface support portion 331.

[0054] The backrest support portion 332 has a fourth surface fastener portion 94 at a position corresponding to the second surface fastener portion 92, and the fourth surface fastener portion 94 includes more than one surface fastener set to a shape corresponding to the second surface fastener portion 92. In the present embodiment, the fourth surface fastener portion 94 includes four surface fasteners 941 to 944 respectively corresponding to the four surface fasteners 921 to 924 included in the second surface fastener portion 92. In the present embodiment, the surface fasteners 941 to 944 are formed in a rectangular shape identical to the surface fasteners 921 to 924, and are arranged at a position overlapping with the surface fasteners 921 to 924 when the backrest portion 50 is arranged at an appropriate position relative to the backrest support portion 332.

[0055] As an example, the surface fastener provided on the seat cushion 3 (i.e., the surface fastener 911 included in the first surface fastener portion 91 and the surface fasteners 921 to 924 included in the second surface fastener portion 92) can be configured as a loop portion (so-called concave portion, concave surface, etc.). On the other hand, the surface fastener provided on the seat cushion support portion 30 (the surface fastener 931 included in the third surface fastener portion 93 and the surface fasteners 921 to 924 included in the second surface fastener portion 92) can be configured as a hook portion (so-called convex portion, convex surface, etc.). Thus, when the seat cushion 3 is arranged on the seat cushion support portion 30, the surface fasteners facing each other (i.e., the group of the surface fastener provided on the seat cushion 3 and the surface fastener provided on the seat cushion support portion 30) are engaged with each other.

[0056] In the above-mentioned baby carriage 1, the seat surface 40 of the seat cushion 3 is fixed to the seat surface support portion 331 of the seat cushion support portion 30 via the first surface hook and loop fastener portion 91 and the third surface hook and loop fastener portion 93, and the backrest portion 50 of the seat cushion 3 is fixed to the backrest support portion 332 of the seat cushion support portion 30 via the second surface hook and loop fastener portion 92 and the fourth surface hook and loop fastener portion 94. In this way, by fixing both the seat surface 40 and the backrest portion 50 of the seat cushion 3 to the seat cushion support portion 30 using the surface hook and loop fastener, the seat cushion 3 can be fixed to the seat cushion support portion 30 in a well-balanced and stable manner. In addition, the number of fixing members such as zipper tapes (for example, the same fixing member as the above-mentioned connecting member 101) that are conventionally used to attach the seat cushion to the baby carriage body 2 can be reduced. For example, conventionally, a structure is generally adopted in which at least one set (a pair of left and right) of zipper tapes are provided on the seat surface 40 and the backrest portion 50, respectively, and the zipper tapes are attached to the base seat cushion 33. In the baby carriage 1, by providing the first surface fastener portion 91, the second surface fastener portion 92, the third surface fastener portion 93, and the fourth surface fastener portion 94, as described above, the buckle tapes that were previously provided on the seat surface portion 40 and the backrest portion 50 are omitted. As a result, the cost of the baby carriage 1 can be reduced by reducing the number of components, and the loading and unloading operation of the seat cushion 3 can be simplified. Furthermore, the user can fix the seat cushion 3 to the seat cushion support portion 30 only by pressing the seat surface portion 40 and the backrest portion 50 of the seat cushion 3 to the position corresponding to the seat cushion support portion 30, and can remove the seat cushion 3 from the seat cushion support portion 30 only by pulling (pulling) the seat cushion 3 from the seat cushion support portion 30. That is, by using the surface fastener as the main component for mounting the seat cushion 3 on the seat cushion support portion 30, the seat cushion 3 can be intuitively and easily mounted and dismounted relative to the seat cushion support portion 30. Therefore, according to the baby carriage 1, the convenience of mounting and unmounting the seat cushion 3 can be improved.

[0057] The one or more surface fasteners (the surface fasteners 911 in the present embodiment) included in the first surface fastener portion 91 are formed into a shape (a rectangular shape as an example in the present embodiment) whose length in the left-right direction (Y-axis direction) is longer than the length in the front-back direction (X-axis direction). In addition, the one or more surface fasteners (the surface fasteners 931 in the present embodiment) included in the third surface fastener portion 93 have a shape corresponding to the one or more surface fasteners (the surface fasteners 911 in the present embodiment) included in the first surface fastener portion 91. As in the present embodiment, typically, the frame of the stroller body 2 (for example, the armrests 13, etc.) is arranged on both sides of the seat surface support portion 331 of the seat cushion support portion 30 in the left-right direction (Y-axis direction). In contrast, as Figure 2As shown, the frame as described above is not arranged in front of the seat surface support part 331. Therefore, when the seat surface support part 331 fixes (carries) the seat surface 40 of the seat cushion 3, the possibility of the seat surface 40 relative to the seat surface support part 331 being offset in the left-right direction (Y-axis direction) is small, and on the other hand, the position of the seat surface 40 relative to the seat surface support part 331 may be offset in the front-back direction (X-axis direction). Assuming that the surface fastener 911 included in the first surface fastener part 91 or the surface fastener 931 included in the third surface fastener part 93 is formed into a shape in which the length in the front-back direction (X-axis direction) is longer than the length in the left-right direction (Y-axis direction), even if the position of the seat surface 40 of the seat cushion 3 relative to the seat surface support part 331 is offset to a certain extent in the front-back direction (X-axis direction), the first surface fastener part 91 (surface fastener 911) and the third surface fastener part 93 (surface fastener 931) will contact and fix each other. In contrast, by forming the surface fasteners 911 and 931 included in the first surface fastener portion 91 and the third surface fastener portion 93 into a shape in which the length in the left-right direction (Y-axis direction) is longer than the length in the front-back direction (X-axis direction), the first surface fastener portion 91 and the third surface fastener portion 93 are not easily in contact with each other when the seat surface portion 40 is offset in the front-back direction (X-axis direction) relative to the seat surface support portion 331. As a result, it is possible to prevent the seat surface portion 40 from being fixed to the seat surface support portion 331 in a state in which it is offset in the front-back direction (X-axis direction) relative to the seat surface support portion 331.

[0058] The seat cushion 3 includes a connecting member 102 (see FIG. 1 ) provided near the boundary (connection line L1) between the seat portion 40 and the backrest portion 50 (in the present embodiment, near both ends of the connection line L1 in the left-right direction (Y-axis direction)). Figure 6 ). In addition, the stroller body 2 has a frame member (in this embodiment, the connecting rod member 14) connected to the connecting member 102. In this embodiment, the connecting member 102 has the same structure as the connecting member 101. The connecting member 102 is a buckle belt, which has a belt portion 102a fixed to the back surface 4b of the seat cushion 3, and a pair of buckles 102b provided at both ends of the belt portion 102a. By winding the belt portion 102a around the side surface of the connecting rod member 14 and locking the pair of buckles 102b to each other (that is, the concave portion and the convex portion to each other), the baby stroller body 2 has a frame member (in this embodiment, the connecting rod member 14) connected to the connecting member 102. In this way, ... Figure 1As shown, the connecting member 102 is fixed relative to the link member 14. According to the above configuration, the seat cushion 3 can be fixed to the seat cushion support portion 30 by the connecting member 102, while the boundary portion (connecting line L1) between the seat portion 40 and the backrest portion 50 of the seat cushion 3 is aligned to an appropriate position. Thus, for example, by causing the seat portion 40 to swing with the above boundary portion as the swing axis and press against the seat support portion 331, the seat portion 40 can be easily fixed to an appropriate position relative to the seat support portion 331 (i.e., a position where the surface fastener 911 and the surface fastener 931 just overlap). Similarly, by causing the backrest portion 50 to swing with the above boundary portion as the swing axis and press against the backrest support portion 332, the backrest portion 50 can be easily fixed to an appropriate position relative to the backrest support portion 332 (i.e., a position where the surface fasteners 921~924 and the surface fasteners 941~944 just overlap). In this way, by using the connecting component 102 to properly align the boundary position between the seat portion 40 and the backrest portion 50, the position alignment of the seat portion 40 and the backrest portion 50 can be easily performed, thereby improving the convenience of the installation operation of the seat cushion 3. In addition, by using the surface fastener and the connecting component 102 together, the number of connecting components can be reduced to improve the convenience of the installation operation, and the stability of the seat cushion 3 can be improved. For example, the boundary between the seat portion 40 and the backrest portion 50 is suppressed from shifting in the front-to-back direction (X-axis direction) relative to the seat cushion support portion 30 by the connecting component 102. As a result, the entire seat cushion 3 can be prevented from moving significantly in the front-to-back direction (X-axis direction) due to the movement of an infant sitting on the seat cushion 3, and the fixation caused by the surface fastener of the seat portion 40 or the backrest portion 50 relative to the seat cushion support portion 30 can be suppressed from falling off.

[0059] The second surface fastener portion 92 includes a plurality of surface fasteners (four surface fasteners 921 to 924 in the present embodiment). In addition, the fourth surface fastener portion 94 includes a plurality of surface fasteners 941 to 944 corresponding to the plurality of surface fasteners 921 to 924 included in the second surface fastener portion 92. According to the above-mentioned structure, the area of ​​each surface fastener 921 to 924 and 941 to 944 required for fixing the backrest portion 50 with sufficient strength relative to the backrest support portion 332 can be miniaturized. Thus, since it is possible to avoid obstructing the air permeability of a specific part of the backrest portion 50 due to the provision of a large surface fastener, the comfort of the infant riding in the stroller 1 can be maintained.

[0060] The second surface fastener portion 92 is disposed at a position along the edge 51 of the backrest 50. Correspondingly, the fourth surface fastener portion 94 is disposed at a position along the edge of the backrest support portion 332. According to the above configuration, by not providing the surface fastener in the area overlapping with the central portion of the backrest 50, the breathability of the portion of the backrest 50 that mainly contacts the back of the infant can be ensured, thereby maintaining the comfort of the infant riding in the stroller 1. For example, in the case where the backrest 50 is formed of a raw material with good breathability such as a mesh fabric, the gaps in the mesh fabric are closed due to the surface fastener provided in the area overlapping with the central portion of the backrest 50, thereby preventing the breathability of the portion that mainly contacts the back of the infant from being obstructed.

[0061] The second surface fastener portion 92 includes at least a surface fastener (surface fasteners 922, 923 in this embodiment) provided along the edge 51a of the backrest portion 50 on the side opposite to the side connected to the seat portion 40. According to the above configuration, the backrest portion 50 is fixed to the backrest support portion 332 at a position as far away from the seat portion 40 as possible, so that the backrest portion 50 can be stably supported relative to the backrest support portion 332.

[0062] The seat cushion support portion 30 includes a support frame (a backrest support frame 32 in the present embodiment) which is formed along a second portion 51c (in the middle) of the edge 51 of the backrest portion 50 except for a first portion 51b (i.e., a portion along the connection line L1) connected to the seat surface portion 40. Figure 6 The edge 51 is formed in the form of an inverted U-shaped portion (including the edge 51a) other than the first portion 51b of the edge 51. In addition, a suppression component 103 for suppressing deformation of the edge 51 is provided in the second portion 51c of the backrest portion 50. According to the above-mentioned structure, the backrest portion 50 can be easily and appropriately aligned with the backrest support portion 332 by pressing the second portion 51c of the edge 51 of the backrest portion 50 along the backrest support frame 32. In addition, the suppression component 103 provided in the second portion 51c suppresses the deformation of the second portion 51c, so that the above-mentioned operation can be easily performed, and the support stability of the backrest portion 50 can be improved.

[0063] In the present embodiment, the suppression member 103 is formed by a covering member that is rolled along the second portion 51c. According to the above configuration, the suppression member 103 can be easily and reliably provided by using a covering member (e.g., a rolling tape) that is rolled along the second portion 51c. In addition, the visual recognition and appearance of the backrest portion 50 along the portion relative to the backrest support frame 32 are improved by the rolling, so that the user can easily arrange the backrest portion 50 at an appropriate position relative to the seat cushion support portion 30 by using the rolling portion (covering member) as a mark. It should be noted that in the present embodiment, as Figure 6 As shown, the suppression member 103 extends to the edge of the seat surface portion 40 that is continuous with the edge 51 of the backrest portion 50 , and is also formed between the seat surface portion 40 and the side wall portion 80 .

[0064] Although one embodiment of the present disclosure has been described above, the present disclosure is not limited to the above embodiment. The material and shape of each component are not limited to the above materials and shapes, and various materials and shapes can be adopted.

[0065] For example, the structure of the stroller body 2 of the stroller 1 in the above embodiment is only an example, and may have a frame structure different from that in the above embodiment. In addition, the seat cushion 3 only needs to have at least the seat surface 40 and the backrest 50, and other structures (such as the cover 70) may be omitted.
