Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat in which a child seat is integrally incorporated.

[0002]

2. Description of the Related Art Conventionally, there are various types of children's seats, which are roughly classified into a type that is separated from an adult seat and a type that is incorporated in an adult seat. An example of the latter type is disclosed in Japanese Utility Model Laid-Open No. 63-34632. Hereinafter, this structure will be briefly described with reference to FIGS. 10 to 12.

As shown in FIG. 10, the seat back 3
00 has its center portion excluding its lower end portion 300A, headrest 300B and both side portions 300C divided in the vehicle front-rear direction, and its front portion further divided in the vehicle up-down direction. The upper part on the front side is the abdomen protection pad 302 for children, and the lower part on the front side is the seat cushion 304 for children.

According to this structure, the state shown in FIG. 10 is the stored state of the child seat, that is, the used state as the adult seat. When used as a child seat, as shown in FIG. 11, the child seat cushion 304 is rotated around a support shaft 305 (see FIG. 12) to be embedded in the child abdomen protection pad 302. The plate 306 is adapted to be engaged with the buckle device 308 that stands upright from the child seat cushion 304.

Further, as shown in FIG. 12, a pair of child restraining belts 31 are provided on the child abdominal protection pad 302.
One end of 0 is locked. This child restraint belt 31
The other end of 0 passes through the upper portion of the seat back 300 in the thickness direction, passes through the back surface of the seat back 300, and is wound up by the winding device 314 arranged at the lower end portion of the seat cushion 312.

[0006]

However, according to this structure, the buckle device 308, which is one supporting position of the child restraint belt 310, and the winding device 314, which is the other supporting position, are separated from each other. . Therefore, the load applied to the child restraint belt 310 at the time of sudden deceleration of the vehicle is reduced by the buckle device 308 side, the support shaft 305 side of the child seat cushion 304 on which the buckle device 308 is erected, and the winding device 314 side. Must be supported in place.
Therefore, there is a problem that each part must be sufficiently reinforced in order to secure the supporting strength.

Further, in the case of this structure, it is necessary to pull out the child restraint belt 310 from the winding device 314 to penetrate the upper end portion of the seat back 300, and at the same time, the tongue plate 306 is attached to the front end portion of the child restraint belt 310.
Also, since the work of attaching the child's abdominal protection pad 302 is required, there is a problem that assembly workability is reduced.

In view of the above facts, an object of the present invention is to obtain a vehicle seat integrated with a child seat which can be lightly reinforced and can be improved in assembly workability.

[0009]

According to a first aspect of the present invention, one end portion of a winding device provided on an adult seat is locked and the upper body of a child seated on a child seat cushion is restrained. A vehicle seat integrated vehicle seat having a child restraint belt, wherein the child restraint belt is fixed to a member on the adult seat side at at least one location and at a location different from the one location. It is characterized in that it is guided along the upper body of the child and is connected in a loop shape as a whole.

According to a second aspect of the present invention, there is provided a child restraining belt for restraining an upper body of a child seated on the child seat cushion, and a child seat having an adult seat cushion and an adult seat back. An integrated vehicle seat, characterized in that the child restraint belt is integrally assembled to a panel assembled to the adult seat back.

According to a third aspect of the present invention, in the first aspect of the present invention, a fixing member to which the other end of the child restraint belt is locked is integrally formed with a member on the adult seat side. It is characterized in that it is arranged at a portion on the vehicle rear side of the provided frame having a predetermined strength.

According to a fourth aspect of the present invention, in the first aspect of the present invention, a fixing plate to which the other end of the child restraint belt is locked is arranged at the lower end of the member on the adult seat side. In addition, the locking portion of the other end of the child restraint belt in the fixing plate extends toward the vehicle front side, and the tip end of the fixing plate is curved toward the vehicle lower side.

[0013]

According to the first aspect of the present invention, the child restraint belt is fixed to the member on the adult seat side at at least one location, and along the upper body of the child at another location than the one location. Since it is guided like this and is connected in a loop as a whole, the number of attachment points on the seat side of the child restraint belt is reduced compared to the conventional structure in which the child restraint belt is not connected in a loop. . Moreover, since the child restraint belt is connected in a loop shape as a whole, the load applied to the child restraint belt is offset to some extent by the inertial movement of the child when the vehicle rapidly decelerates.

Further, since the child restraint belt is guided along the upper body of the child at a position different from the position fixed to the member on the adult seat side, the child restraint belt is properly worn. Is obtained.

According to the second aspect of the present invention, since the child restraint belt is integrally assembled to the panel that is assembled to the adult seat back, the child restraint belt winding device is conventionally used. After pulling out from the seat, the complicated work of penetrating the upper part of the adult seat back and further locking the tongue plate and the child's abdomen protection pad is eliminated.

According to a third aspect of the present invention, in the first aspect of the present invention, a fixing member to which the other end of the child restraint belt is locked is integrally provided on the adult seat side member. Since the child restraint belt is arranged at a portion on the vehicle rear side of the frame having a predetermined strength, the load applied to the child restraint belt by the inertial movement of the child during the vehicle rapid deceleration is efficiently transmitted to and supported by the frame.

According to a fourth aspect of the present invention, in the first aspect of the present invention, the locking portion of the other end of the child restraint belt in the fixing plate is extended to the front side of the vehicle.
When the child is seated, the cost of the child restraint belt on the child's abdomen (particularly near the flank) is reduced. Moreover, since the front end of the fixing plate is curved toward the vehicle lower side, it is possible to avoid the front end of the fixing plate being positioned close to the adult's buttocks when the adult is seated.

Next, the belt component 58 is assembled to the seat back panel 30. That is, the base portion 62A of the lower belt anchor 62 is fixed to the seat back panel 30 with the fixing bolt 70. At this time, the winding device 84 is also fastened together with the fixing bolt 70. Then
A base portion 60A of the upper belt anchor 60 is fixed to the seat back panel 30 with a fixing bolt 64. As a result, the belt component 58 and the seat back panel 3
0 and 1 are integrated.

Next, the tip portion 62 of the lower belt anchor 62.
Rear cloth hinge 1 of C and upper seat cushion 100
14 are connected by a hog ring 120. As a result, the child seat cushion 98 becomes lower belt anchor 6
Connected to 2.

Then, the seat back 18 is assembled to the seat back panel 30. Next, the child seat back board 42 is placed in contact with the upper end surface of the board fixing bracket 40. At this time, the shoulder belts 80 and 82 are attached to the pair of belt insertion holes 4 of the child seat back board 42.
Insert into Nos. 6 and 48. Then, in this state, the clip 44 is inserted and locked in the board fixing bracket 40, so that the child seat back board 42 is attached to the seat back panel 30.

Finally, the hook-and-loop fastener 28 under the seat back 18 and the child seat cushion board 122.
The seat fastener board 122 of the child is seated on the child seat back board 42 by combining the surface fastener 129 of the child seat back board 42 and the seat fastener 52 of the child seat back board 42 and the surface fastener 131 of the child seat cushion board 122. It is attached to the front.

As described above, the child seat-integrated vehicle seat 10 is assembled. After the assembly work is completed, the child seat cushion 98 is stored. That is, by fitting the hook-and-loop fasteners 110 of the hooks 108 of the lower seat cushion 102 with the hook-and-loop fasteners 24 at the lower part of the headrest rest of the seat back 18, the child seat cushions 98 are stored in a state of being vertically arranged on the front surface of the seat back panel 30. To be done.

Next, a child seat integrated vehicle seat 1
A method of using 0 will be described. When the child seat integrated vehicle seat 10 is used as an adult seat, FIG.
Sit in the illustrated state on the right side of. In this case, since the tip portion 62C of the lower belt anchor 62 is curved toward the vehicle lower side, the tip portion 62C of the lower belt anchor 62 is positioned away from the seated adult buttock.

On the other hand, a child seat-integrated vehicle seat 1
When 0 is used for children, it is in the illustrated state on the left side of FIG. That is, the hook fastener 11 of the hook 108
After 0 is peeled off from the hook-and-loop fastener 24 at the lower portion of the headrest, two sheets are stacked and placed in the recess 22 of the seat cushion 16. At this time, the crotch belt 90 and the buckle device 92 are passed through the opening 104 of the upper seat cushion 100. Then, the child seat cushion board 122 is peeled off from the child seat backboard 42 and attached to the surface of the upper seat cushion 100.

Thereafter, the child is seated on the child seat cushion board 122, and the tongue plates 94 and 96 of the shoulder belts 80 and 82 are engaged with the buckle device 92. As a result, the child is put on the shoulder belts 80 and 82. At this time, since the upper belt anchor 60 has a hanger shape, the shoulder belts 80, 82
Is guided to fit the child's upper body.

In this mounted state, since the tip portion 62C of the lower belt anchor 62 extends toward the front side of the vehicle through the intermediate portion 62B, the shoulder belts 80, 82 locked to the tip portion 62C are provided. Also, the locking portion of the crotch belt 90 is closer to the abdomen of the child. Therefore, the shoulder belts 80, 82 are less likely to be worn on the abdomen of the child.

Further, when the vehicle suddenly decelerates in this state,
The child inertially moves to the front side of the vehicle. Upon inertial movement, the child is restrained by shoulder belts 80 and 82. More specifically, the base portion 62A of the lower belt anchor 62 and the winding device 84
Since it is fastened together with the flange 84A of the frame of FIG.
0, 82 and the belt portion wound by the winding device 84, the belt formed into a loop as a whole,
The child will be detained. Therefore, the load applied to the shoulder belts 80 and 82 during sudden deceleration of the vehicle is offset to some extent by the load applied to the tip portion 62C of the lower belt anchor 62 and the load applied to the winding device 84 in the belt withdrawing direction. It becomes the load except. That is, the acting load on the seat back panel 30 side is reduced.

As described above, in this embodiment, the lower belt anchor 62 having the end portions of the shoulder belts 80 and 82 locked and the frame flange 84A of the winding device 84 are fastened together to the seat back panel 30, and the whole structure is secured. As the child restraint belt is made to be a loop, the shoulder belt 8
It is possible to concentrate the locking portions of 0 and 82 in almost one place. Therefore, as compared with the conventional structure, the number of parts that require a predetermined supporting strength is reduced, and thus the overall degree of reinforcement can be reduced to that extent. Moreover, since the child restraint belt is looped as a whole, the lower belt anchor 6
With the arrangement position of 2, it is possible to offset the load acting at the time of sudden deceleration of the vehicle to some extent. Therefore, also from this point, the degree of reinforcement can be reduced.

Further, in this embodiment, since the belt component 58 is manufactured in advance and assembled to the seat back panel 30 with the fixing bolts 64 and 70, the assembly of the child restraint system parts is completed. It is possible to eliminate complicated work such as inserting the shoulder belts 80 and 82. Therefore, the child seat integrated vehicle seat 10
It is possible to improve the workability of assembly. It should be noted that the hook-and-loop fasteners 24, 28, 52, 110, 129, 13 are everywhere.
Since 0, 131, and 132 are used, the assembling workability can be improved also from this point.

Further, in this embodiment, since the tip portion 62C of the lower belt anchor 62 extends toward the front side of the vehicle through the intermediate portion 62B, the engaging portions of the shoulder belts 80 and 82 and the crotch belt 90 are fixed. You can take it to the front of the vehicle. Therefore, the shoulder belts 80, 82 are less likely to be stretched over the child's abdomen, and therefore the feeling of pressure on the child's abdomen by the shoulder belts 80, 82 can be suppressed. Moreover, since the front end portion 62C of the lower belt anchor 62 is curved toward the vehicle lower side, even when an adult is seated when the child seat 14 is stored, a foreign body sensation does not occur.

In this embodiment, the lower belt anchor 6
Although the bent portion of the middle portion 60B of 0 is arranged on the front side of the lower end portion 32A of the seatback pipe frame 32, the present invention is not limited to this, and the configuration shown in FIGS. 7 and 8 may be adopted.
