DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a child seat striker mounting structure which is provided at two places on a frame provided along the width direction of a seat and is engaged with a child seat lock mechanism.

[0002]

2. Description of the Related Art A child seat fixing method (ISO-Fix) conforming to the ISO (International Organization for Standardization) standards for the purpose of preventing misuse of a child seat, improving vehicle compatibility, and internationally unifying the mounting method was established in January 1999. It was decided.

[0003] The child seat fixing method of this standard is as follows.
As shown in FIG. 4, each end side of the substantially U-shaped strikers 1, 1 'having two ends and an intermediate portion engaged with the lock mechanism of the child seat is provided in the width direction of the seat. The two are fixed to each other by being wound around the peripheral surface of the frame 3 from above and welding the wound portion.

The strikers 1, 1 'are arranged between the seat back 5 and the seat cushion 7, as shown in FIG. On the other hand, the child seat 9 has a lock mechanism 11 that can be disengaged from the strikers 1 and 1 '.
Insert the child seat 9 in the direction of the arrow, and
The child seat 9 is fixed by engaging 1 with the strikers 1 and 1 '.

[0006] As shown in FIG. 6, the striker frame 3 is attached by winding the ends of the substantially U-shaped strikers 4, 4 ′ from below on the peripheral surface of the frame 3. In some cases, the two parts are fixed to each other by welding the wound parts.

[0006]

When a large force acts on the child seat 9 due to a vehicle collision or the like, the above configuration has the following problems.

(1) A striker 1 as shown in FIG.
In the case of 1 ′, as shown in FIG.
Acts on the child seat 9, a moment in the direction of arrow M1 is generated.

[0008] Due to the moment M1, an upward force f1 as shown in FIG. 8, ie, welding of the end portions of the strikers 1, 1 'and the frame 3, is applied to the intermediate portion of the strikers 1, 1'. A force acts in the direction of peeling the location.

Since the strength of welding is weak in the direction of peeling, in the above case, the welded portions are peeled and the strikers 1 and 1 'are easily deformed. (2) In the case of the strikers 4, 4 'as shown in FIG. 6 When a forward force acts on the child seat 9, a force for pushing the end portions of the strikers 4, 4' toward the frame 3 acts, and , 4 '.

[0010] However, as shown in FIG. 9, when a force F2 laterally (obliquely rightward) as viewed from the occupant is applied to the child seat 9, as shown in FIG. Moment is generated.

Due to the moment M2, a downward force f is applied to an intermediate portion of the striker 4 on the right side as viewed from the seated person.
2 has an upward force f in the middle of the left striker 4 '.
2 'acts.

In this case, there is a problem that the welded portion between the end portion of the striker 4 and the frame 3 is peeled off and the striker 4 'is easily deformed. Conversely, the child seat 9
When a force in the diagonally left direction acts on the striker 4, there is a problem that the striker 4 is easily deformed.

[0013] The present invention has been made in view of the above problems, and an object of the present invention is to provide a striker mounting structure in which the deformation of the striker is reduced even when a force is applied to the child seat in any direction. is there.

[0014]

According to the first aspect of the present invention,
In a child seat striker mounting structure provided at two places of a frame provided along the width direction of the seat and engaged with a child seat lock mechanism, each of the strikers has two ends, and an intermediate part is The lock mechanism of the child seat is substantially U-shaped, and each end side is wound along the peripheral surface of the frame, and the wound portion is welded to the frame to attach to the frame, and the end of each striker is The direction in which the side of the frame is wound around the peripheral surface is different from each other.

Each of the strikers has two ends, an intermediate portion having a substantially U-shape with which the lock mechanism of the child seat is engaged, and each end side being wound along the peripheral surface of the frame. By welding the attachment points, the striker is attached to the frame, and the direction of winding the end portion side of each striker with respect to the peripheral surface of the frame is made different from each other, so that an upward or downward force is applied to each striker. Even if it acts, one end side is wound around the frame in a direction in which the welding strength is strong, so that the amount of deformation of the striker is reduced.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view illustrating a mounting structure of a striker according to an embodiment of the present invention.

In the drawing, two strikers 21 and 23 are attached to a frame 13 provided in the width direction of the seat. The strikers 21 and 23 have two ends, and the intermediate portions 21a and 23a are substantially U-shaped with which a child seat lock mechanism is engaged.

Of the two ends of the striker 21, the outer end 21b in the width direction of the sheet is the frame 1
3 is wound from the upper side, and the inner end side 21c
Is wound around the frame 13 from below, and is attached to the frame 13 by welding the wound portion.

Of the two ends of the striker 23, the outer end 23b in the width direction of the sheet is the frame 1
3 is wound from the upper side, and the inner end side 23c
Is wound around the frame 13 from below, and is attached to the frame 13 by welding the wound portion.

That is, the directions in which the strikers 21 and 23 are wound around the peripheral surface of the frame 13 at the ends are different from each other. According to the above configuration, the direction of winding the strikers 21 and 23 around the peripheral surface of the frame 13 at the end portions is different from each other, so that an upward or downward force acts on each striker 21 and 23. However, one end side of the frame 1
3, the amount of deformation of the strikers 21, 23 is reduced.

The present invention is not limited to the above embodiment. In the above embodiment, the outer ends 21b and 23b of the strikers 21 and 23 are connected to the frame 1
3 from the upper side, the inner end side 21c, 2
Although the description has been given of the configuration in which the outer side 3c is wound around the frame 13 from the lower side, as shown in FIG.
b and 73b are wound around the frame 13 from below,
The strikers 71, 73 in which the inner end portions 71c, 73c are wound around the frame 13 from above may be used.

Even in such a configuration, each striker 7
Even if an upward or downward force is applied to the first and third ends, the one end side is wound around the frame 13 in a direction in which the welding strength is strong, so that the amount of deformation of the strikers 71 and 73 is reduced.

As shown in FIGS. 3 (a) and 3 (b), the strikers 121, 12 of the same shape in which the directions of winding around the peripheral surface of the end frame 13 are different from each other.
1 ′ and the strikers 221 and 221 ′ may be attached to the frame 13.

Even in such a configuration, each striker 1
Even if an upward or downward force is applied to the strikers 21 and 121 'and the strikers 221 and 221', one end is wound around the frame 13 in a direction in which the welding strength is strong. ', Striker 221,
221 'is less deformed.

[0025]

As described above, according to the first aspect of the present invention, each of the strikers has two ends, and the middle portion is substantially U with which the child seat lock mechanism is engaged.
It is in the shape of a letter, and each end is wound along the peripheral surface of the frame, and the winding portion is welded to the frame, and the striker is wound around the peripheral surface of the frame at the end side. Since the directions are different from each other, even if an upward or downward force is applied to each striker, one end is wound around the frame in the direction where the welding strength is strong, so the striker deformation The amount is reduced.
