2. Description of the Related Art Conventionally, various mounting structures (seat belt anchorages) have been used for a three-point seat belt for a rear row center seat.
Has been adopted. Among them, there is a structure in which a retractor is incorporated in a roof portion behind a rear-row center seat, and a seat belt fed out from the retractor is drawn into a vehicle interior from an opening in the roof portion, or is wound around the retractor. Further, since the seat belt is of a three-point type, it is provided with two tongue plates, and a space for accommodating these tongue plates is also secured on the roof near the retractor. This storage space has a structure in which two tongue plates are stacked in two layers and stored. When these tongue plates are stored, they are stored using the retracting force of the retractor or the elasticity of the seat belt (webbing). Has gained holding power.

[0003]

If two tongue plates are stored in an overlapping manner as described above, the size of the storage space in the thickness direction becomes large. The tongue plate is composed of a small tongue plate for anchoring and a large tongue plate for restraining the occupant. A large and large tongue plate is stored under the small tongue plate. Therefore, the width of the storage space protruding into the vehicle interior becomes large, and as a result, it is necessary to secure a large space in the roof part for storing the tongue plate.

[0004] With the structure in which the retractor is incorporated in the roof portion as described above, it is not impossible to secure a large storage space for the tongue plate. However, it is difficult to secure the space in the upper rear part of the rear seats in the rear row, which makes it difficult to secure a space for storing the tongue plate in the roof part with the structure in which the retractor is incorporated in the column on the side of the vehicle body. If the space is forcibly secured, the head clearance between the occupant and the roof cannot be sufficiently secured, or the design of the roof may be sacrificed.

An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to reduce a storage space for a tongue plate in both a thickness direction and a width direction to secure a sufficient head clearance and to improve a design of a roof portion. This is to increase the degree of freedom.
