Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicular child seat, and more particularly to a child seat in which a surface back pad of a seat back is removed to form a recess and a child is seated in the recess.

[0002]

2. Description of the Related Art Conventionally, as this type of child seat, the one disclosed in Japanese Patent Application Laid-Open No. 5-162574 is known. 12 to 14 show the child seat. The seat surface of the seat back 1 is composed of a central pad 2 that supports the back surface along the spine and side pads 3 and 3 that support the seated person from the back side. The lower portion 2a of the central pad 2 has a lower end. As the fulcrum, the upper end is rotated and can be pulled down toward the front side.
b is divided into left and right parts, and the center side is rotatable about 90 degrees forward with the left and right end parts as fulcrums.

When a child is to be seated, as shown in FIG. 13, the lower portion 2a is pulled down to the front side and the left and right upper portions 2b and 2b are respectively turned to the front side to form a recess on the surface of the seat back 1. Then sit down there. Here, in order to rotate the left and right upper portions 2b, 2b and hold them in an upright state, metal hinge mechanisms 4, 4 as core materials are attached to the left and right ends.

[0004]

In the above-mentioned conventional child seat, the hinge mechanisms 4 and 4 made of metal are embedded on the side of the child's head, but the feeling is not good because it is made of metal and hard. There were challenges.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a child seat which can improve the feeling when a child is seated and can have a simple structure.

[0006]

In order to achieve the above object, the invention according to claim 1 is such that, when the front surface pad of the seat back is disengaged to form a concave portion as a seating position for a child, the upper portion of the front surface pad is formed. In a child seat that is divided into left and right to form a split pad, is supported on the side of the recess to form a wall body, and laterally supports the head of the child. It is configured so as to be overlapped and fixed to the side pads that are not removed from the seat back.

According to a second aspect of the present invention, in the child seat according to the first aspect, each of the division pads has a cloth-like side at a surface portion adjacent to the side pad in a state of being arranged in the recess. They are sewn to each other with a side connecting cloth, and when the center end of the split pad is pulled out, the connecting cloth becomes a hinge and the split pad is wound around and fixed to the side pad surface. It is a configuration to assist in. Further, the invention according to claim 3 is the child seat according to claim 1 or claim 2, wherein both of the split pads are connected to end portions in contact with each other, and the split pad is housed in the recess. When it is folded back outward to cover the surface, and when the same split pad is pulled out and wound around the surface of the side pad to be fixed, the end of the connected split pad is pulled to the rear of the seat back and the other end is used for the seat. The surface cloth fixed to the back surface of the back is provided.

Further, the invention according to claim 4 is the invention according to claim 1.
According to the third aspect of the present invention, in the child seat according to the third aspect, the split pads are provided with engaging members that can be attached to and detached from each other on the surfaces of the ends that are in contact with each other.

[0009]

In the invention according to claim 1 configured as described above, the split pad is removed from the seat back of the front pad when it is removed from the surface of the seat back to form a recess as a seating position for children. The child's head is supported by stacking and fixing it on a side pad that is not removed, and forming a wall on the side of the recess. In other words, the split pad is not erected with a hinge structure or the like, but is simply overlaid on the side pad, and this alone forms a wall body that is sufficiently tall if the surface of the recess is used as a reference. Will support the department.

Further, in the invention according to claim 2 configured as described above, since the side connecting cloths are sewn to each other at the surface portions adjacent to the respective division pads and the side pads, the center side of the division pad is the same. When the end part of the pad is pulled out, the connecting cloth serves as a hinge, and also acts to fix the end part when the split pad is wound around the surface of the side pad. That is, since the end of the split pad is fixed by sewing the cloth-like side connecting cloth, the split pad acts as a hinge and is fixed so that the end of the split pad does not lift from the side pad. And maintain it as a tall wall.

Further, in the invention according to claim 3 configured as described above, a surface cloth is connected to the end portions of the split pad which are in contact with each other, and when the split pad is housed in the recess, the same is applied. The surface cloth is folded back to cover the surface, and when pulling out the split pad and winding and fixing the split pad around the surface of the side pad, pull the end of the split pad connected to the rear of the seat back,
The other end is fixed to the back surface of the seat back. The surface of the split pad that is exposed when it is pulled out faces the inner surface of the recess when it is stored, and the surface that faces the side pad when it is pulled out faces the surface of the seat back when it is stored. Therefore, it is preferable that the pad insertion port is not formed on the entire surface. Since it is not possible to insert the pad into a place without an entrance, attach a surface cloth that can cover the surface facing the seat back during storage to expose or cover one surface of the split pad. It is possible to do. The insertion port can be formed.

Further, when the split pad is wound around the side pad surface, it must be fixed so as to be in close contact with the curved surface, and if the split pad and the side pad are directly fixed on the curved surface, the split pad is divided. Since the force of the pad to return to its original shape directly acts to peel off the fixed portion, it is necessary to fix the pad with a large force. However, the front cloth pulls the end of the split pad to the rear of the seat back and fixes it to the back of the seat back,
Since the dividing pad changes the direction of the force to return to the original shape, the fixing force can be small. further,
In the invention according to claim 4 configured as described above,
The locks provided on the surfaces of the end portions of both split pads that are in contact with each other face each other when the split pads are housed in the recesses and lock each other, and separate when pulled out. Since the attachment surface of the locking tool is not in a position facing the human body during storage and during withdrawal, a foreign object is not generated.

[0013]

As described above, the present invention provides a child seat that can improve the feeling because it forms a wall body that laterally supports the head of a child without using a core material. You can Further, according to the invention of claim 2, it is possible to make the operation difficult and the structure simple by only connecting with the cloth. Further, according to the invention of claim 3, the insertion position of the pad can be secured and the fixing to the side pad can be facilitated only by connecting the surface cloths. Further, according to the invention of claim 4, since the engaging member is provided at the position where the split pads face each other, it is possible to prevent the obstruction at any time.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a child seat according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along the i plane in FIG. In the figure,
The vehicle seat 10 includes a seat cushion 20 and a seat back 30 that is held so as to stand upright from a rear end of the seat cushion 20. A pad is attached to the outer surface of the seat back 30, and the seat surface pad 31 occupies most of the widthwise center of the seat surface.
Side pads 32, 32 are provided on both sides of the seat surface pad 31 so as to project slightly forward. Further, the seat surface pad 31 can be detached from the seat back 30 in a predetermined direction to form a recess 33 as a seating position for a child. That is, a portion from the lower end to slightly above the middle in the vertical direction is provided with a plate-shaped core material inside, and the upper end serves as a child seat cushion portion 34a that can be pulled down toward the front side, The portion above this is divided into left and right split pads 34b, 34b at the center in the width direction. As shown in FIG. 2, the seat back 30 includes a frame-shaped back frame 36 that supports a frame, and the back frame 36 supports the pad.

The split pad 34b is a thin box-shaped main pad portion 3 as shown in FIG. 2 and FIG.
7, a connecting cloth 38 for connecting one side of the main pad portion 37 to the adjacent side pad 32, and a surface cloth 39 sewn to the opposite side of the main pad portion 37. The main pad portion 37 sews a rectangular cloth and a cloth of the same shape with a gusset on its four sides as shown in FIG.
As shown in FIG. 5, it is configured to accommodate a thin box-shaped cushion member 37a. Here, the cushion material 3
Fasteners 37 on the side of the rectangular cloth to insert 7a.
B1 is sewn to form an opening 37b that can be opened and closed. The fastener 37b1 is provided on the side facing the front of the seatback 30 with the division pad 34b housed in the recess.

The connecting cloth 38 has the same width as the vertical direction of the main pad portion 37, and as shown in FIG. 6, one end of the connecting cloth 38 is on the front side when the main pad portion 37 is accommodated in the recess 33 on the side surface. Is sewn to the side, and the other end is sewn to the sewn portion of the recess and the side pad 32.
Therefore, the connecting cloth 38 overlaps the gusset in the main pad portion 37 and overlaps with the main pad portion 37 and the seat back 3.
0 and fixed. The surface cloth 39 also has the same width as the vertical width of the main pad portion 37, and as shown in FIG. 6, one end of the surface cloth 39 is in front of the inner side surface when the main pad portion 37 is stored in the recess 33. 2 and the other end is folded back and is pressed between the connecting cloth 38 and the side pad 32 as shown in FIG. A male side hook 39a is provided at the pushed-in end portion, and a female side hook 39b paired with the male side hook 39a is fixed to the back surface of the seat back 30 as shown in FIG. As for the mounting position, as shown in FIG.
When the main pad portion 37 is wound around the front surface of the side pad 32 from the side to the back surface as it is, the hook 3 on the male side is attached to the back surface of the seat back 30.
9a is a position facing each other.

A pair of Magic Fasteners (registered trademark) 37c serving as locking tools are attached to the side surfaces that come into contact with each other when the main pad portions 37, 37 are housed in the recess 33. In the present embodiment, the split pad 34b is wound around the side surface pad 32 by the connecting cloth 38 and the surface cloth 39, but it is removed from the recess 33 and fixed on the side surface pad 32. It suffices if it is designed to project forward. Therefore, the connecting cloth 3
Instead of providing 8 or the surface cloth 39, the fastener may be directly stopped by a magic fastener or a hook. However, in this case, the magic fastener needs to have a hook or the like attached to the seating surface, and if the magic fastener is configured to be wound around the side surface pad 32 by the connecting cloth 38 or the surface cloth 39, it is fixed to the seating surface. It is not necessary to attach the above-mentioned member, and there is an effect that there is no sense of foreign matter. The shape of the main pad portion 37 does not necessarily have to be a rectangular thin box shape, and the thickness does not have to be constant. For example, if the thickness of the end portion of the main pad portion 37 is tapered, the wall surface of the side pad 32 changes gently when fixed on the side pad 32, so that a corner cannot be formed. Further, an air bag may be formed inside in order to adjust the thickness, and the air bag may be inflated as necessary to increase the thickness.

Although the main pad portion 37 is connected to the side surface pad 32 via the connecting cloth 38, the main pad portion 37 can be directly sewn to the side surface pad 32 without necessarily via the connecting cloth 38. However, by interposing the connecting cloth 38, the sewing is performed in accordance with the stitching surface of the side pad 32, and the sewing can be performed at the same time. It can also be sandwiched between. Regarding the width of the connecting cloth 38, it is not necessary to cover the entire width of the main pad portion 37, and a plurality of belts may be used as a narrow width. The surface cloth 39 is not necessarily required if the end portion of the main pad portion 37 is fixed on the side surface pad 32. However, when forming the pad insertion opening 37 in the main pad portion 37, it is necessary to hide the fastener 37a, and the surface cloth 39 is effective also in the sense of hiding this.

In order to fix the main pad portions 37, 37 in the recess 33, there are various methods other than the fasteners provided on the abutting surfaces as in this embodiment. However, if the abutting surfaces are locked to each other, the abutting surfaces do not affect the seating surface and the foreign object feeling does not occur during storage and use. Of course, other than magic fasteners, hooks or fasteners can be used. Next, the operation of this embodiment having the above configuration will be described. When the child is not seated, as shown in FIGS. 1 and 2, the child seat cushion portion 34a stands up and is accommodated in the recess 33,
The split pads 34b, 34b are arranged side by side so that the recess 3
It is housed in 3. At this time, the main pad portions 37, 3
The magic fasteners 37c provided on the abutting surface of 7 are engaged with each other to prevent the recesses 33 from coming off. The surface cloth 39 is folded back on the surface of each main pad portion 37 to cover the surface, and the end portion is inserted between the bridge connecting cloth 38 of the main pad portion 37 and the side surface pad 32. Is held. The surface cloth 39 is the main pad portion 37
The insertion port 37b in is covered so that it cannot be seen from the outer surface. When the child is seated, as shown in FIG. 8, the upper end of the child seat cushion portion 34a is pulled down to the front side, and the surface cloth 39 is placed in front of the seatback 30 as shown in FIGS. While the main pad portion 37 is wound around the surface like the side surface pad 32, the hook 39a at the end portion is pulled out to the seat back 3
It is fixed to the hook 39b on the back of 0. Then, the main pad portion 37 is fixed on the side surface pad 32 while forming the recess 33 in the seat back 30 and protrudes forward to form a wall body that is retained laterally of the recess 33. Therefore, when the child is seated as shown in FIG. 11, the head of the child is laterally supported by the same wall body. Here, when fixing the main pad portion 37 onto the side surface pad 32, a skeleton structure is not required, and a foreign body sensation is not generated.

As described above, since the pads on the seat surface of the seat back 30 are removed to form the split pads 34b and 34b, which are fixed so as to be wound around the surface of the side pad 32, the thickness of the side pad 32 and the main pad Due to the thickness of the portion 37, a wall is formed on the side of the recess 33. Therefore, the child's head can be laterally supported without the need for a skeleton.
