[0003] [Patent Document 1] JP 2002-46517 A Summary of the Invention [Problem to be solved by the invention]

[0004] The striker for fixing the child seat is usually placed in a position that is difficult to see, for the sake of appearance. Therefore, when the mounting legs of the child seat are inserted through the opening of the seat, there is a risk that they will be inserted in a position that is misaligned with the striker, and the mounting legs will not be engaged with the striker. In this case, the mounting legs are inserted all the way, so even if they are not engaged with the striker, it is mistakenly believed that the child seat is installed completely. In addition, since electrical components such as the harness connector for the seat are installed near the striker, if the mounting legs are inserted in a misaligned position, the mounting legs may come into contact with the electrical components and cause damage to the electrical components.

[0005] In view of the above, an object of the present invention is to provide a protective structure for a child seat mounting portion that can prevent the mounting legs of the child seat from being inserted all the way into a position misaligned with the striker. [Means for solving the problem]

[0006] In the present invention, a striker for engaging the mounting legs of a child seat is provided on a mounting bar installed inside the vehicle cabin, and at the child seat mounting section where electrical components are arranged below the striker, a protective cover for protecting the electrical components from the mounting legs of the inserted child seat is attached to the mounting bar, and the protective cover is integrally formed from an engagement portion that engages with the mounting bar, a shielding portion that covers the electrical components, and a fitting portion that is fitted into the striker to position the protective cover.

[0007] If the mounting leg is inserted out of place, the mounting leg will not come into contact with the striker but will come into contact with the shielding portion and will not be inserted any further. This prevents the mounting leg from coming into contact with electrical components below. Effect of the Invention

[0008] According to the present invention, even if the mounting legs of the child seat are inserted misaligned from the striker, the mounting legs are prevented from coming into contact with the electrical components, thereby protecting the electrical components. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] 1 to 3 show an attachment portion of a child seat according to an embodiment of the present invention. A child seat 1 is attached to a rear seat 5 arranged in the vehicle interior and composed of a seat cushion 2, a seat back 3 and a headrest 4. An attachment portion 6 of the child seat 1 compatible with ISO-FIX is located behind the rear seat 5 and has an attachment bar 7 provided on the floor panel and a striker 9 for engaging an attachment leg 8 of the child seat 1. The striker 9 is fixed to the attachment bar 7, and an electrical component 10 is disposed below the striker 9.

[0011] A mounting bar 7 made of a metal pipe extending in the vehicle width direction is installed at the lower rear of the seat back 3, and its left and right ends are supported by support brackets 11 fixed to the floor panel. A plurality of strikers 9 made of sheet metal are attached to the mounting bar 7 by welding. Four strikers 9 are attached at predetermined intervals, resulting in two pairs of left and right strikers 9. The strikers 9 protrude forward, with their front ends facing a gap 12 formed between the seat back 3 and the seat cushion 2.

[0012] The electrical component 10 below the striker 9 is a harness connector for a seat belt reminder. Note that the electrical component 10 is not limited to this harness connector, and may be a harness connector for a battery, or the like.

[0013] A pair of left and right mounting legs 8 protrude rearward from the rear of the child seat 1. When the child seat 1 is placed on the rear seat 5, the mounting legs 8 are inserted into the gap 12 and engaged with the front end of the striker 9.

[0014] 4 and 5, a protective cover 20 is attached to the mounting bar 7 as a protective structure for the mounting portion 6 of the child seat 1 against the inserted mounting legs 8, and protects the electrical components 10 from the inserted mounting legs 8. The resin protective cover 20 is integrally formed with an engagement portion 21 that engages with the mounting bar 7, a shielding portion 22 that covers the electrical components 10, and a fitting portion 23 that fits into the striker 9 to position the protective cover 20.

[0015] The engagement portion 21 is formed in a semi-cylindrical shape extending in the vehicle width direction to match the external shape of the mounting bar 7, and is hollowed out to reduce weight. The protective cover 20 is attached to the mounting bar 7 by fitting and engaging the engagement portion 21 with the mounting bar 7. Ribs 24 are formed on both ends of the engagement portion 21 in the vehicle width direction, making it difficult for the semi-cylindrical engagement portion 21 to open and preventing the engagement portion 21 from coming off the mounting bar 7.

[0016] The shielding portion 22 is formed to protrude forward from the engaging portion 21, and the front side is bent downward. The shielding portion 22 is disposed on the outer side of the engaging portion 21 in the vehicle width direction in accordance with the position of the electrical component 10. The inner side of the engaging portion 21 faces the striker 9.

[0017] The fitting portion 23 has a U-shaped cross section so that it can be inserted into the outer side edge of the striker 9, and is formed so as to protrude forward from the center of the engaging portion 21 in the vehicle width direction and rise from the inner side edge of the shielding portion 22. Since the shielding portion 22 and the fitting portion 23 are integrally formed with the engaging portion 21 in this manner, it is possible to ensure sufficient rigidity around the engaging portion 21. Furthermore, since the fitting portion 23 is provided in the center of the engaging portion 21 in the vehicle width direction, it is possible to ensure a stable engagement force and make it difficult for the protective cover 20 to shift due to external disturbances.

[0018] When attaching the protective cover 20, the fitting portion 23 is inserted into the side edge of the striker 9 while aligning it with the side edge of the striker 9, and the engagement portion 21 is fitted into the mounting bar 7. The fitting portion 23 fits into the side edge of the striker 9, thereby positioning the protective cover 20 and preventing the engagement portion 21 from rotating. Furthermore, the fitting portion 23 covers the side edge of the striker 9 made of sheet metal, thereby hiding burrs and edges of the sheet metal and eliminating any adverse effects on other objects.

[0019] In addition, a shielding portion 22 is positioned above the electrical component 10, and the electrical component 10 is covered by the shielding portion 22. In this case, if liquid such as water is spilled onto the rear seat 5, it will flow down from the gap 12 to the mounting portion 6, but the liquid will not reach the electrical component 10 covered by the shielding portion 22, and the electrical component 10 can be prevented from getting wet and the electrical component 10 can be protected.

[0020] Next, when attaching the child seat 1 to the rear seat 5, the mounting legs 8 are inserted into the gaps 12 of the rear seat 5. When the mounting legs 8 come into contact with the strikers 9 and are further inserted, the mounting legs 8 are engaged with the strikers 9, and the child seat 1 is attached to the rear seat 5.

[0021] Here, if the child seat 1 is placed misaligned on the rear seat 5, the mounting legs 8 will be inserted at a position misaligned from the striker 9 and will come into contact with the shielding portion 22 of the protective cover 20. Since the mounting legs 8 cannot be inserted any further, it is possible to inform the user that the mounting legs 8 are not properly engaged, and to urge the user to reinstall the child seat 1. In particular, since the front side of the shielding portion 22 is bent downward, it is possible to prevent the mounting legs 8 from being inserted toward the electrical component 10, and the electrical component 10 can be protected by preventing the mounting legs 8 from coming into contact with the electrical component 10.

[0022] It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that many modifications and changes can be made to the above-described embodiment within the scope of the present invention. As shown in Fig. 6, a protective cover 20 may be provided on both the left and right sides of the striker 9. The left and right protective covers 20 are shaped to be line-symmetrical to each other. Providing two protective covers 20 is a suitable form when a plurality of electrical components 10 are provided below the striker 9. Here, the left and right separate protective covers 20 may be integrated. [Explanation of symbols]
