In the illustrated example, the seat body 20 includes a seat surface portion 21 and a rear wall portion 22 connected to the seat surface portion 21 from the rear. The seat surface portion 21 is a portion facing the buttocks of the child seated in the child seat 10 . The rear wall portion 22 is a portion opposite to the back of the child. As shown in FIG. 2 , a locking recess 23 for locking the headrest 30 is formed in the rear wall portion 22 . In addition, the seat body 20 includes a pair of side wall portions 24 and 24 connected to the seat surface portion 21 and the rear wall portion 22 from the side surfaces.

Next, the headrest 30 will be described. The headrest 30 can move up and down with respect to the seat body 20 between the position shown in FIG. 2 and the position shown in FIG. 4 . As shown in FIGS. 1 to 4 , the headrest 30 has: a headrest main body 31 facing the head of the child seated in the child seat 10; and a headrest foot 35 extending from the headrest main body 31 into the seat main body 20 inside the rear wall portion 22;

The headrest main body 31 includes: a central wall part 32 facing the back of the head of the child seated in the child seat 10; and a pair of side wall parts 33 extending forward from both ends of the central wall part 32 to be opposite to the back of the head of the child seated in the child seat 10. The child's lateral brain is opposite. To the rear surface of the center wall portion 32, a headrest-side fastener 34 for fixing a canopy member 76 to be described later is fixed.

As shown in FIGS. 2 to 4 , the headrest leg portion 35 includes a leg portion main body 36 extending downward from the lower end of the central wall portion 32 , and a pair of leg portion engaging portions 37 extending from the foot portion main body 36 . The lower end extends downward. The pair of leg engaging portions 37 are separated from each other in the width direction. Each leg engaging portion 37 includes a leg extending portion 38 extending linearly downward from the leg main body 36 , and a leg protrusion 39 extending from the leg at the lower end of the leg extending portion 38 . The portion 38 protrudes inward and outward in the width direction. The leg extension portion 38 has flexibility and can bend in the width direction.

The headrest operating portion 40 is arranged to face the rear surface of the central wall portion 32 of the headrest main body 31 and the leg portion main body 36 of the headrest leg portion 35 , and is arranged along the leg portion engaging portion 37 at the pair of leg portion engaging portions 37 . extending up and down. Although the headrest operation part 40 is arranged to be movable up and down with respect to the center wall part 32 and the leg part main body 36 , the headrest operation part 40 is relative to the center wall part 32 and the feet by means of an urging device not shown. The main body 36 is urged downward. The lower end portion of the headrest operation portion 40 is provided with an operation portion protruding portion 41 protruding outward in the width direction toward each leg portion engaging portion 37 of the headrest leg portion 35 . The operation portion protruding portion 41 is provided corresponding to the leg portion protruding portion 39 of the leg portion engaging portion 37 . When the headrest operating portion 40 is not operated, the operating portion protruding portion 41 abuts the leg portion protruding portion 39 from the inner side in the width direction, and prevents the leg portion extending portion 38 from bending inward in the width direction. On the other hand, when the headrest operating portion 40 is operated to move upward relative to the leg engaging portion 37 , the operating portion protruding portion 41 is disposed at a position that does not face the leg protruding portion 39 when viewed in the width direction. , the leg extension 38 is allowed to flex inward in the width direction.

When the headrest operating part 40 is not operated in a state where the leg protrusions 39 of the headrest leg 35 are fitted into the locking recesses 23 provided in the rear wall 22 of the seat body 20, the headrest leg 35 Since the leg extension portion 38 cannot be bent inward in the width direction, the leg protrusion portion 39 cannot be pulled out from the locking recess 23 of the seat body 20 . Therefore, the headrest 30 is maintained in a locked state with respect to the seat body 20 . That is, the headrest 30 is prevented from moving relative to the seat body 20 . On the other hand, if the headrest operating portion 40 is operated to allow the leg extension portion 38 of the headrest leg portion 35 to bend inward in the width direction, the leg protrusion portion can be pulled out from the locking recess 23 of the seat body 20 . 39. Therefore, when an upward or downward force is applied to the headrest main body 31 and the headrest leg portion 35 in a state where the headrest operating portion 40 is operated, the movement of the leg portion protruding portion 39 relative to the locking concave portion 23 causes the The leg extending portion 38 is deflected inward in the width direction (see FIG. 3 ), and the leg protrusion 39 is pulled out from the locking recess 23 . Then, the headrest 30 moves upward or downward with respect to the seat body 20 .

In addition, as can be understood from FIGS. 2 to 4 , a plurality of locking recesses 23 of the seat body 20 are provided along the vertical direction. Therefore, when the headrest 30 is moved up and down with respect to the seat body 20 , the headrest 30 can be fixed at an arbitrary height with respect to the seat body 20 (see FIGS. 2 and 4 ).

Next, the canopy device 50 will be described. As shown in FIGS. 5 and 6 , the canopy device 50 can move up and down with the movement of the headrest 30 .

The canopy device 50 includes a pair of holders 51 respectively fixed to each of the pair of side wall portions 33 of the headrest 30 , and a canopy 60 held by the pair of holders 51 .

First, the holder 51 will be described with reference to FIG. 7 . The pair of holders 51 and 51 are fastened to the side wall portions 33 and 33 of the headrest by bolts, respectively. The holder 51 fixed to the one side wall portion 33 is configured in the same manner as the holder 51 fixed to the other side side wall portion 33 . Hereinafter, the holder 51 fixed to the one side wall portion 33 will be described as an example.

The holder 51 has: a base part 52 facing the side wall part 33 of the headrest 30; a front wall part 53 extending from the front end of the base part 52 to the outside in the width direction of the seat body 20; and a protruding part 54 from the front The wall portion 53 protrudes rearward and upward. The protruding portion 54 and the base portion 52 are connected by a connecting portion 55 extending in the width direction. Between the protruding portion 54 and the base portion 52, an upper groove portion 56a having the upper surface of the connection portion 55 as a bottom, and a lower groove portion 56b having the lower surface of the connection portion 55 as a bottom surface are formed. These grooves 56a and 56b accommodate a part of the canopy base member 61 described later in a state in which the canopy 60 is held by the holder 51 .

Regarding the protruding portion 54 , when the headrest 30 is at the position shown in FIG. 2 , in other words, when the headrest 30 is arranged at the position where the upper end 30a of the headrest 30 is closest to the upper end 20a of the seat body 20 In the position, the protruding portion 54 is along the edge portion 24 a of the side wall portion 24 of the seat body 20 . Thereby, the canopy 60 can be easily attached to and detached from the holder 51 from the rear of the child seat 10 .

Next, the canopy 60 will be described. 2 to 6 more clearly, the canopy 60 includes: a pair of canopy base parts 61, which are connected with the holding member 51; Part 61 is connected;

8, the tent base member 61 is demonstrated. The roof base member 61 connected to the holder 51 fixed to the one side wall portion 33 of the headrest 30 and the roof base member 61 connected to the holder 51 fixed to the other side wall portion 33 of the headrest 30 are configured similarly. Hereinafter, the tent base member 61 connected to the holder 51 fixed to the one side wall portion 33 will be described as an example.

The tent base part 61 has: a first base part 62 which is connected with the holder 51 ; and a second base part 63 which is pivotally connected with the first base part 62 .

The first base portion 62 has: a connecting portion 64 , which becomes a connecting portion with the holder 51 ; and a first pivot portion 62 a , which is pivotally connected with the second base portion 63 . A concave portion 65 for accommodating the protruding portion 54 of the holder 51 is formed on the side of the connection portion 64 facing the holder 51 . The concave portion 65 extends from the lower front to the upper rear. The inner side wall portion 66 facing the base portion 52 of the holder 51, the outer side wall portion 67 facing the inner side wall portion 66 in the width direction, and the upper wall connecting the inner side wall portion 66 and the upper edge portion of the outer side wall portion 67 part 68a, a lower wall part 68b connecting the lower edge parts of the inner side wall part 66 and the outer side wall part 67, and a rear wall part 69 connecting the rear end parts of these wall parts 66, 67, 68a, 68b, thereby dividing Recess 65 . By opening the front end portion of the recessed portion 65 , the protruding portion 54 of the holder 51 can be accommodated from the front of the first base portion 62 . In addition, the protruding portion 54 accommodated in the recessed portion 65 can be pulled out from the front of the first base portion 62 . Thereby, the canopy 60 can be easily attached and detached from the rear of the holder 51 (ie, of the bicycle 2 ). In addition, since the rear end part of the recessed part 65 is closed by the rear wall part 69, it can prevent that the 1st base part 62 connected to the holder 51 moves forward and falls off from the holder 51. The inner side wall portion 66 has an upper portion 66a extending downward from the upper wall portion 68a and a lower portion 66b extending upward from the lower wall portion 68b. In a state where the first base portion 62 is connected to the holder 51 , the upper portion 66 a and the lower portion 66 b of the inner side wall portion 66 are accommodated in the upper groove portion 56 a and the lower groove portion 56 b of the holder 51 , respectively. Thereby, it can prevent that the 1st base part 62 connected to the holder 51 moves in the width direction and falls off from the holder 51.

The first base portion 62 also has a claw portion 70 that engages with the holder 51 . The claw portion 70 has an extension portion 71 that extends forward and downward from the rear portion of the lower wall portion 68b of the first base portion 62 , and an abutting portion 72 that protrudes upward from the front end of the extension portion 71 to engage with the holder 51 . The front surface of the front wall portion 53 abuts. Such a claw portion 70 can prevent the first base portion 62 connected to the holder 51 from moving rearward and upward to be detached from the holder 51 . It should be noted that the extension portion 71 has flexibility, and by pressing the front end (contact portion 72 ) of the extension portion 71 downward, the extension portion 71 is flexed, and the engagement between the claw portion 70 and the holder 51 can be released. .

The second base portion 63 has: a second pivoting portion 63a pivotally connected with the first pivoting portion 62a of the first base portion 62 ; and a awning bone holding portion 63b holding the corresponding end of the awning bone 75 . The second pivot portion 63 a can rotate relative to the first base portion 62 about the rotation axis Ax extending in the width direction. The hood holding portion 63b extends from the outer peripheral surface of the second base portion 63 to the radially outer side of the circle centered on the rotation axis Ax. The hood holding portion 63b has a concave portion (not shown) extending in the radial direction. By accommodating the end portion of the awning bone 75 in the concave portion, the awning bone 75 is held on the second base portion 63 .

As shown in FIG. 9 , by rotating the second base portion 63 relative to the first base portion 62 , the hood 75 can be swung relative to the headrest 30 .

The hood 75 is formed of a substantially narrow plate-shaped or linear metal and/or resin or the like. A canopy member 76 is attached to the canopy bone 75 .

The canopy member 76 may be formed of a soft material capable of shielding sunlight. In the example shown in the figure, it is formed of a mesh material in order to ensure air permeability. Of course, the material for forming the canopy member 76 is not limited to the mesh material. Various known materials can be used for the canopy member 76 . For example, the canopy member 76 may be formed of a resin film material in order to effectively shield the wind, rain and/or dust. Moreover, you may form with the cloth which has water repellency and/or water repellency.

In the example shown in FIGS. 5 and 6 , the canopy member 76 is attached to the canopy bone 75 at its front end edge 76a. Moreover, the hood side fastener 77 is provided in the rear-end edge 76b of the hood member 76. As shown in FIG. The rear end edge 76b is detachably fixed to the headrest-side fastener 34 provided in the headrest 30 via the roof-side fastener 77 . Since the rear end edge 76b of the canopy member 76 is fixed to the rear surface of the headrest 30, and the front end edge 76a of the canopy member 76 is attached to the canopy bone 75, the canopy member 76 is moved as the canopy bone 75 swings relative to the headrest 30. Expand or collapse. In addition, as the roof side fastener 77 and the headrest side fastener 34, various fasteners can be employ|adopted, for example, a set of snaps, a hook-and-loop fastener surface, a hook-and-loop fastener, etc. can be used.

In a state where the canopy member 76 is unfolded, in order to prevent the canopy member 76 from loosening, an auxiliary core rod 78 rich in flexibility is built in the canopy member 76 . The auxiliary core rod 78 is different from the awning bone 75 in that it is not connected to the awning base member 61 .

The seating space of the child seat 10 is defined by the seat surface portion 21 of the seat body 20 , the pair of side wall portions 24 and 24 , and the canopy device 50 attached to the headrest 30 . As described above, the canopy device 50 is fixed to the headrest 30 that can move up and down with respect to the seat body 20 . Therefore, the seating space of the child seat 10 expands or contracts with the movement of the headrest 30 relative to the seat body 20 . That is, if the headrest 30 is moved upward with respect to the seat body 20, the above-mentioned seating space can be enlarged. On the other hand, if the headrest 30 is moved downward with respect to the seat body 20, the aforementioned seating space can be reduced. Therefore, children of various heights can be appropriately covered without using a large-sized canopy. That is, the canopy 60 can be downsized. In addition, by moving the headrest 30 downward with respect to the seat body 20, it is possible to reduce the size of the child seat 10 in the up-down direction in which the seating space is enlarged.

In addition, by removing the canopy 60 from the holder 51 and the headrest side fastener 34 , the size of the child seat 10 in the up-down direction can be further reduced. In particular, in the illustrated example, the protrusion 54 extending to the rear and upper side of the holder 51 is accommodated in the recess 65 of the canopy base member 61 so that the canopy 60 is held by the holder 51 . Therefore, the canopy 60 can be easily attached and detached from the rear of the bicycle 2 . This approach is advantageous in particular in the case where the child seat 10 is a rear child seat that is fixed to the rear portion of the bicycle 2 .

In addition, in the said example, although the child seat to which the canopy apparatus 50 is attached is the rear side child seat 10 attached to the rear part of the bicycle 2, it is not limited to this. The child seat to which the canopy device 50 is attached may be the front child seat 100 that is attached to the front portion of the bicycle 2 . That is, the canopy device 50 may be attached to the headrest 130 of the front child seat 100 . In this case, only by moving the headrest 130 up and down relative to the seat body 120 of the front child seat 100 , the seating space of the front child seat 100 can be enlarged and reduced. Furthermore, by moving the headrest 130 downward with respect to the seat body 120, the size of the child seat in the up-down direction with the enlarged seating space can be reduced.

In addition, the above-mentioned canopy base member 61 , the canopy bone 75 and the holder 51 constitute a support device 80 that supports the canopy member 76 . In the illustrated example, the support device 80 includes a holder 51 fixed to the side wall portion 33 of the headrest 30 , and a support structure 81 held by the holder 51 . The support structure 81 includes the awning base member 61 and the awning bone 75 . In the illustrated example, the support device 80 supports the canopy member 76, but it is not limited to this. For example, the support device 80 may be a member that supports a rain cover covering the seat body 20 . In this case, only by moving the headrest 30 up and down with respect to the seat body 20, the seating space divided by the seat body 20 and the rain cover can be enlarged and reduced. Furthermore, by moving the headrest 30 downward with respect to the seat body 20, the size in the up-down direction of the child seat 10 having an enlarged seating space can be reduced.

As described above, according to the present embodiment, the bicycle child seat 10 includes the seat body 20 , the headrest 30 that can move up and down with respect to the seat body 20 , and the canopy device 50 attached to the headrest 30 . According to the bicycle child seat 10 with the canopy device 50 , the seating space of the child seat 10 partitioned by the canopy device 50 and the seat body 20 can be expanded and reduced by simply moving the headrest 30 up and down. Therefore, the canopy 60 can be miniaturized. In addition, the size of the bicycle child seat 10 in which the seating space is enlarged can be reduced simply by moving the headrest 30 downward with respect to the seat body 20 .

In addition, according to the present embodiment, the canopy device 50 includes: the holder 51 fixed to the side wall portion 33 of the headrest 30; , the canopy 60 has a recess 65 that accommodates the protrusion 54 . Such a bicycle child seat 10 is easy to attach and detach the canopy 60 from the rear of the bicycle child seat 10 . This approach is advantageous in particular in the case where the child seat 10 is a rear child seat that is fixed to the rear portion of the bicycle 2 .

Alternatively, according to the present embodiment, the bicycle child seat 10 includes a seat body 20 , a headrest 30 that can move up and down with respect to the seat body 20 , and a support device 80 attached to the headrest 30 . According to the bicycle child seat 10 with the support device 80 , the seating space of the child seat 10 partitioned by the support device 80 and the seat body 20 can be enlarged and reduced simply by moving the headrest 30 up and down. Therefore, the size of the support device 80 can be reduced. In addition, the size of the bicycle child seat 10 in which the seating space is enlarged can be reduced simply by moving the headrest 30 downward with respect to the seat body 20 .

Further, according to the present embodiment, the support device 80 includes the holder 51 fixed to the side wall portion 33 of the headrest 30 , and the support structure 81 held by the holder 51 having a protrusion protruding toward the rear and upward part 54 , the support structure 81 has a concave part 65 that accommodates the protruding part 54 . Such a bicycle child seat 10 can be easily attached to and detached from the support structure 81 from the rear of the bicycle child seat 10 . This approach is advantageous in particular in the case where the child seat 10 is a rear child seat that is fixed to the rear portion of the bicycle 2 .

In addition, according to the present embodiment, when the headrest 30 is arranged at the position where the upper end 30a of the headrest 30 is closest to the upper end 20a of the seat body 20, the protruding portion 54 is along the edge of the side wall portion 24 of the seat body 20 part 24a.
