Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to a child seat fixing structure for restraining the child seat with a seat belt in a vehicle interior.

<<Prior Art>> To ensure safety, a child seat used in a vehicle interior must be secured by fixing the child seat body to the vehicle seat so that it will not be moved, especially by vibrations.

In this case, a seat belt that is generally installed on a vehicle seat is used as the fixing means. When securing an occupant with a seat belt, the child seat itself is relatively small and easily slips out of the seat belt, so simply securing the occupant to a vehicle seat cannot securely restrain the occupant, which may cause vibrations, etc. There is a risk that the seat belt may become attached and come off the seat belt.

For this reason, in this type of fixing structure, belt insertion holes are provided on the sides and back of the child seat body, so that after the child seat body is placed on the vehicle seat facing forward or backward, ,
The pulled-out end of the seat belt had to be inserted into the belt insertion hole and then tightened and locked.

[Problems to be solved by the invention] Therefore, the fixing structure in which the pull-out end of the seat belt passes through the insertion hole in the child seat body not only requires more effort than restraining the occupant, but also This is extremely troublesome because it must be carried out indoors with the child seat main body set in a fixed position. The present invention was devised in view of the above circumstances, and aims to further improve the usability of this type of child seat by allowing smooth fixation with a seat belt.

<Means for Solving the Problems> In other words, the present invention is a fixed structure in which a child seat main body is restrained to a vehicle seat by a seat belt, and the child seat main body is rotatable to both outer sides thereof. A substantially Z-shaped locking member is provided, and the rotating end of the locking member is selectively locked to a locking member provided in front of the seat side portion and above the backrest side portion of the child seat main body. , the seat belt is hooked onto the Z-shaped bent portion.

<<Operation>> The child seat body is fixed by rotating the locking member and locking its rotating end to a locking member provided in front of the seat side or above the backrest side, and then folding the child seat into a substantially Z-shaped fold. This is done by hooking and locking the drawn end of the seat belt on the curved part.

It is also possible to carry the child seat by using the locking member whose rotating end is locked, or to hang an umbrella or the like on the approximately Z-shaped bent portion.

<<Example>> Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 3.

FIG. 1 is an overall perspective view showing the child seat fixing structure. In the figure, the child seat includes a bucket-type child seat main body 3 that integrates a seat part 1 and a backrest part 2, a pair of shoulder rest bands 4 pulled out from holes provided in the front of the backrest part 2, and each A breast pad 5 is provided which is detachably connected to the tip of the shoulder band 4, and the infant accommodated in the child seat body 2 can be appropriately held by the shoulder band 4 and the breast pad 5.

Further, on both outer sides of the child seat main body 3, substantially Z-shaped locking members 6 that are pivotally supported are provided. Then, the rotation end 6 of the locking member 6
1 is locked, the seat belt 12 attached to the vehicle seat 11 is attached to the bent portion 6a of the locking member 6.
The child seat body 3 is fixed to the seat 11 by inserting the tongue 13, which is the pull-out end of the seat, and then inserting and locking the tongue 13 into a buckle (not shown) provided on the floor side.

As shown in FIG. 2, the locking member 6 is formed by bending a pipe or the like into a substantially Z shape.
The seat belt 12 is hooked onto the bent portions 6a and 6b. A mounting hole 62a is provided in the pivot end 62 of the locking member 6, and the seat portion 1
It is rotatably attached to the end of the reinforcing reinforcement 7a, which is inserted in the left-right direction inside, by a pivot screw 8 inserted through a washer 81 or the like. Further, a locking pin 9 is provided at the rotating end 61 of the locking member 6, and this locking pin 9 is connected to a lock provided in front of the seat side portion 1a and above the backrest side portion 2a of the child seat body 3. Part 10
It is locked by selectively engaging with a and 10b.

The locking members 10a and 10b have a structure in which a locking pin 9 is inserted into an open bearing portion to lock them, and for example, a reinforcing reinforcement 7b is inserted inside the seat portion 1 and the backrest portion 2 in the left-right direction. , 7c with a set screw or the like. After the rotation of the locking member 6 is locked by the locking member 10b, the child seat body 3 is attached to the vehicle seat 11 by inserting the tongue 13, which is the pulled-out end of the seat belt 12, as shown in FIG. It can be easily and securely fixed to the side.

FIG. 3 is a side view showing a state in which the child seat main body 3 is fixed rearward.

When fixing the child seat main body 3 rearward in this way, the lower rear corner portion 3a of the child seat main body 3 is placed on the seat cushion 11a, and the lower front corner portion 3b is placed on the seat back 11b.
Then, the upper corner portions 3c are respectively locked to the dash board 14 of the automobile, and the Z-shaped folding is performed using the locking member 6 which is rotated clockwise and locked to the locking member 10a of the seat side portion 1a. Curved part 6b
The seat belt 12 is hooked and fixed in the same manner as described above.

FIG. 4 shows a modification of the locking members 10a, 10b. That is, in this modification, locking pins 100 are provided in place of the locking members 10a and 10b in front of the seat side 1a and above the backrest side 2a of the child seat body 3, respectively.
Grooves 90 are provided at the upper and lower positions of the rotating end 61 of the locking member 6.
a, 90b are provided, and the structure is such that the grooves 90a, 90b are engaged with the locking pin 100.

Furthermore, by moving the knobs 91a, 91b in the engaged state, the sealing members 92a, 92b connected to the knobs 91a, 91b seal the grooves 90a, 90b, and the grooves 90a, 90b do not come off from the locking pin 100. As a result, rotation of the locking member 6 is locked.

As described above, the locking member is not limited to that of this embodiment, and it goes without saying that various known locking means can be used.

<<Effect of the invention>> As explained above, according to the fixing structure of the invention, the pull-out end of the seat belt is hooked through the locking members rotatably provided on both outer sides of the child seat body. Therefore, even in a narrow vehicle interior, the child seat main body can be easily fixed in the forward or rearward position, and moreover, it can be fixed as securely as before.

Additionally, the child seat can be carried around using the locking member with its rotating end locked, or an umbrella, etc. can be hung on it, which further improves the usability of this type of child seat. .
