<First Embodiment>
In the first embodiment shown in FIGS. 1 to 6, a tip-up function is added to a so-called 6-4 divided seat for the rear seat of the vehicle, and a seat belt buckle 40 is arranged in the divided portion of the left and right divided seats. It is installed. In FIG. 1, 31A is a 4-side seat cushion, 31B is a 6-side seat cushion, 32A is a 4-side seat back, 32B is a 6-side seat back, 37A is a 4-side headrest, and 37B and 37C are 6-side seat cushions. Two headrests are shown. Reference numeral 20 denotes a link member disposed on both sides of the seat belt buckle 40. Reference numeral 60 denotes a luggage board (corresponding to a rear structure in the present invention) disposed behind a seat back (not shown).
FIG. 2 is a view of the 4-side sheet as viewed from the 6-side sheet side without describing the 6-side sheet of the 6-4 divided sheet. Here, the seat back 32A is fixed to the vehicle floor 50 via hinge brackets 33 disposed on both sides of the seat back 32A, and the seat cushion 31A is provided with a strength member 25 (see FIG. 6) and is rotatably fixed by a rotating shaft 35 on the hinge bracket 33.
A rear end of the seat back 32A is in contact with a front end portion of a luggage board 60 disposed in the luggage compartment of the vehicle, and the seat belt buckle 40 is attached to the cross member 37 disposed through the hinge bracket 33 in the vehicle width direction. Is fixed. The upper part of the hinge bracket 33 is covered with a hinge cover 34, and the strength member 25 is covered with the cover member 21 to constitute the link member 20.

As shown in FIG. 3, the link member 20 is provided with a shielding plate 10 on the lower side of the link member 20 in a state where the seat cushion 31 </ b> A is tipped up and set in the retracted position (see FIG. 6). The shielding plate 10 is fixed to the cover member 21 of the link member 20, and when the seat cushion 31 </ b> A is in the retracted position, a space between the link belt 20 and the seat belt buckle 40 positioned below the link member 20. It is set as the magnitude | size which shields from the side (refer FIG. 3, 5).
As shown in FIG. 6, the shielding plate 10 includes a plate 12 that defines the overall shape of the shielding plate 10 and a soft pad 13 for filling a space in the bag 11 inside a bag 11 made of woven fabric. And is wrapped. The bag body 11 is closed at the upper end portion of FIG. 6, and the end portion 14 is inserted into the cover member 21, and is hooked on a projecting piece 22 formed to project into the cover member 21.
In FIG. 6, on both outer sides of the pair of cover members 21, wall portions 23 (corresponding to suppression means in the present invention) are formed integrally with the cover member 21 so as to extend downward, and the shielding plate 10 is the cover member. The movement is suppressed so that it is not bent to the outside of 21.
Therefore, when the seat cushion 31 </ b> A is in the retracted position, the shielding plate 10 hangs down below the link member 20 due to gravity as shown in FIGS. 3 and 5, and the space between the seat belt buckle 40 and the link member 20. Is shielded from the side.

As shown in FIGS. 2 and 4, when the seat cushion 31A returns to the seating position, the link member 20 rotates together with the seat cushion 31A counterclockwise about the rotation shaft 35, and the shielding plate 10 The tip contacts the luggage board 60. Therefore, the shielding plate 10 is bent on the side opposite to the wall portion 23 with the end portion 14 where the bag 11 is inserted into the cover member 21 as a base point. Accordingly, the shielding plate 10 and the luggage board 60 are prevented from being damaged.
When the seat cushion 31A moves from the seating position to the retracted position, the shielding plate 10 hangs down again below the link member 20 to shield the space between the seat belt buckle 40 and the link member 20 from the side surface. At this time, an urging force may be applied between the shielding plate 10 and the cover member 21 so that the shielding plate 10 is surely in this form.

As described above, when the seat cushion 31A is in the retracted position by the tip-up function, the shielding plate 10 protrudes below the link member 20, so that the space formed below the link member 20 at the retracted position is lateral. Can be obscured from. On the other hand, at the seating position of the seat cushion 31A, the shielding plate 10 is bent so as not to protrude from the link member 20. Therefore, the luggage board 60, which is a member disposed around the link member 20 at the sitting position, interferes with the shielding plate 10. Thus, it is possible to suppress the occurrence of problems associated with interference.
If the seat cushion 31A is in the retracted position, the shielding plate 10 automatically protrudes below the link member 20 to cover and conceal the space below the link member 20, and the seat cushion 31A is placed in the seating position. Since the shielding plate 10 is automatically bent when the 10 abuts the luggage board 60, the problem is caused by the interference between the luggage board 60 and the shielding plate 10 at the seating position with a simple configuration. While being suppressed, the space formed below the link member 20 at the retracted position can be covered from the side.
Furthermore, since the shielding plate 10 is configured to be folded only in the direction of the opposite wall portion 23 by the wall portion 23, the folding direction of the shielding plate 10 can be always constant.

<Second Embodiment>
