Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a child seat mounting structure for mounting a child seat on a seat.

[0002]

2. Description of the Related Art Generally, an anchor hook is provided at a lower portion of a child seat and a top tether is provided at an upper portion thereof. The anchor hook is connected to a lower anchor provided on a vehicle frame, and the top tether is connected to a tether anchor provided on a seat back frame of the seat, so that the child seat is attached to the seat.

[0003]

In the conventional vehicle, the tether anchor is welded and fixed to all the vehicles in advance. However, some vehicles do not require a child seat. In the case of such a vehicle, unnecessary parts are increased by the amount corresponding to the tether anchor, and extra work is required for welding the parts. Therefore, there is a problem that the manufacturing cost of the vehicle increases.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to FIGS. 1 to 3 show an embodiment of the present invention, in which a child seat 2 is placed on a seat portion 11 of a seat 1 of a vehicle.
As is well known, at the lower end of the child seat 2, two lower anchor hooks 21 are provided apart from each other in the left-right direction. The lower anchor hook 21 is inserted into the gap between the seat portion 11 and the backrest portion 12 of the seat 1. Two top tether belts 22 are provided on the upper end of the child seat 2 so as to be separated from each other in the left and right directions. The two top tether belts 22 pass through the upper end of the backrest 12 and extend downward. Each top tether belt 2
The tip (lower end) of 2 is connected to one tether hook (connector) 23.

A supporting member 3 is fixed to a frame (not shown) of a vehicle provided with a seat 1 slightly rearward of a seat 11. As shown in FIG. 3, the support member 3 includes a pair of left and right leg portions 3 each having a lower end fixed to a frame and extending vertically.
1, 31 and a support shaft portion 32 that is integrally bridged between the upper end portions of the pair of leg portions 31, 31.
Lower anchors 4 and 4 are fixed to both ends of the support shaft portion 32 in the left-right direction. A lower anchor hook 21 is detachably connected to the lower anchor 4. Thereby, the lower end portion of the child seat 2 is fixed to the frame.

Seatback frame 1 of backrest 12
A tether anchor 5 is provided at 3. That is, the seat back frame 13 includes a pair of side plates 13a, 13a arranged on both left and right sides inside the backrest portion 12.
And an upper connecting member 13b hung between the upper ends of the side plates 13a and 13a, and a lower connecting member 13c hung slightly above the lower ends of the side plates 13a and 13a. Two through-holes 13d and 13d are formed in the center of the lower connecting member 13c in the left-right direction so as to be separated left and right. On the surface of the lower connecting member 13c facing forward,
The female screw members 6 and 6 are fixed by welding or the like. Each screw member 6 is arranged with the axis of the screw hole 61 aligned with the through hole 13d.

The tether anchor 5 has a vertical width that is substantially the same as the vertical width of the lower connecting member 13c, a rectangular mounting plate portion 51 that is long in the horizontal direction, and an inverted concave shape, and extends downward. Engaging shaft 5 having both ends fixed to the mounting plate 51
2 and. Bolt insertion holes 51a, 51a penetrating in the front-rear direction are formed at both ends of the mounting plate portion 51 in the left-right direction. The interval between the bolt insertion holes 51a and 51a is the same as the interval between the through holes 13d and 13d. Therefore, when the mounting plate portion 51 is set at a predetermined position on the rearward facing surface of the lower connecting member 13, the axis lines of the bolt insertion holes 51a, 51a can be aligned with the axis lines of the through holes 13d, 13d, respectively. In this state, the leg portion 71 of the bolt (male screw member) 7 can be inserted into the bolt insertion hole 51a and the through hole 51a and screwed into the female screw member 6. Then, by tightening the bolts 7, the mounting plate portion 51 is detachably attached to the lower connecting member 13c, and by extension, the tether anchor 5 is detachably attached to the seat back frame 13. The tether hook 23 is detachably connected to the engagement shaft 52 of the tether anchor 5. As a result, the upper end portion of the child seat 2 is fixed to the backrest portion (frame) 22, and the lower end portion of the child seat 2 is fixed to the frame via the lower anchor hook 21 and the lower anchor 4. A child seat 2 is detachably fixed to the seat 1.

In the child seat mounting structure configured as described above, since the tether anchor 5 is mounted on the seat back frame 13 by the screw mechanism including the female screw member 6 and the bolt 7 that are screwed together, the child seat 2 is attached. The child seat 2 can be used by attaching the tether anchor 5 to a required vehicle in advance. On the other hand, for vehicles that do not require the child seat 2, the seat back frame 1
By not attaching the tether anchor 5 to 3, it is possible to reduce unnecessary parts, and it is possible to save the labor required to attach the tether anchor 5, thereby reducing the vehicle manufacturing cost. . Moreover, even in a vehicle that initially did not require the child seat 2,
After that, the child seat 2 may be required. In such a case, the tether anchor 5 is set at a predetermined position of the seat back frame 13, the bolt 7 is inserted into the bolt insertion hole 51a and the through hole 13d, and the female screw member 6 is inserted.
The tether anchor 5 can be easily attached to the seat back frame 13 by a simple operation in which the tether anchor 5 is screwed and tightened. Thereby, the vehicle can be changed to a vehicle to which the child seat 2 can be attached.

4 and 5 show another embodiment of the present invention. In this embodiment, the mounting portion 33 is provided at the center of the support shaft portion 32 of the support member 3. Threaded holes 33a, 33a are formed in the wall portion of the mounting portion 33 facing rearward, the distance in the left-right direction being the same as that of the bolt insertion holes 51a, 51a. Then, the bolt 7 that penetrates the bolt insertion hole 51a and is screwed into the screw hole 33a.
By tightening the
3 is detachably attached. Other configurations are
This is similar to the above embodiment. Of course, this embodiment also has the same effect as the above-mentioned embodiment.

The present invention is not limited to the above embodiment, but can be modified as appropriate. For example, in the above embodiment, the seat back frame 13
The female screw member 6 having the screw hole 61 is provided in the seat back frame 13 or the support member 3 is provided with the screw hole 33a. After inserting the tether anchor 5 into the seat back frame 1, the male screw member is screwed into the female screw member and tightened.
3 or the support member 3 may be attached.

[0012]

As described above, according to the present invention, it is possible to prevent the tether anchor from being attached to a vehicle that does not require a child seat, thereby reducing the vehicle manufacturing cost. And even if you didn't need a child seat at first,
A child seat may then be required, in which case the tether anchor can be easily attached to the frame by a screw mechanism, which easily transforms the vehicle into a vehicle in which the child seat can be attached. be able to.
