However, in the configuration disclosed in Patent Document 1, when a worker who manufactures a vehicle, for example, grasps the second board and lays the interior material for the vehicle in the luggage room, the first board is set with reference to the first hinge portion. Due to its own weight, it may hang down on the back surface side (lower surface side) of the second board. In that case, the hanging first board is caught on the floor surface of the luggage room or other members, and the interior material for the vehicle cannot be laid smoothly, and the work efficiency is lowered. In order to prevent such sagging, for example, it is conceivable to attach a non-woven fabric so as to cover the back surface side of the first hinge portion, but since the number of parts increases, labor and cost are required at the time of manufacturing.

The present invention has been completed based on the above circumstances, and one of the objects of the present invention is to provide an interior material for a vehicle that can be smoothly laid on a vehicle. Another further object is to provide interior materials for vehicles that can suppress an increase in manufacturing costs.

A first groove portion which is provided linearly on one surface side and is formed by thinning a part of the plate thickness, which is the main body of the groove section of the hinge portion, and a portion in the middle of the first groove portion. It is characterized in that it is provided with a second groove portion formed of a groove having a depth shallower than that of the first groove portion.

According to such an interior material for a vehicle, since the first groove portion is provided on one surface side (the back surface side), the second plate portion is referred to the hinge portion as the reference to the first plate portion (or the first plate portion). The plate portion can be bent toward the other surface side (the surface side) of the second plate portion. A second groove portion, which is partially formed in the middle of the first groove portion and is composed of a groove shallower than the first groove portion, is provided on the back surface side, so that the second plate is based on the hinge portion. When the portion is bent toward the back surface side of the first plate portion, the second groove portion can be stretched so as to be sandwiched between the hinge portions, and the bending can be suppressed. Therefore, when a worker who manufactures a vehicle, for example, grasps the first plate portion and lays the interior material for the vehicle indoors with the back surface side facing downward, the second plate portion hangs down and the floor surface or the like. It can be laid indoors smoothly without getting caught in the members. Further, in order to prevent such sagging, it is not necessary to provide, for example, a non-woven fabric to be attached so as to cover the hinge portion, and an increase in manufacturing cost can be suppressed.

In the above configuration, the vehicle interior material is a slit that enters inward from the end portion of the vehicle interior material, and includes a slit portion that intersects the hinge portion, and the second plate portion is formed by the slit portion. It has a structure divided into a third plate portion and a fourth plate portion, and the second groove portion is between the first plate portion and the third plate portion, and the first plate portion and the fourth plate portion. It may be provided between the sections.

According to such an interior material for a vehicle, the third plate portion and the fourth plate portion are separated from each other with the hinge portion as a reference depending on the positional relationship between the other member provided in the interior of the vehicle and the interior material for the vehicle. Even if it can be bent separately, the second groove can be stretched so as to be sandwiched between the hinges connected to each plate, and the hinge can be used as a reference to the back side of each plate. Bending can be suppressed.

In the above configuration, the length of the second plate portion in the width direction may be longer than the end portion of the first plate portion on the hinge portion side. According to such an interior material for a vehicle, even the second plate portion, which tends to hang down due to its own weight, can be suppressed from bending toward the back surface side with respect to the hinge portion.

In the above configuration, the vehicle interior material is provided with a concave portion inward from the side end portion of the vehicle interior material so as to avoid other members, and the hinge portion extends inward from the concave portion. It can be said that it is. According to such a vehicle interior material, for example, even if the vehicle interior material has a recess due to the positional relationship with other members, the vehicle interior material has a shape that easily hangs down due to its own weight, but a hinge. It is possible to effectively suppress bending of each plate portion with respect to the portion toward the back surface side.

In the above configuration, the vehicle interior material is made of a plate-shaped base material, and the cross section of the base material can be exposed at the hinge portion. According to such an interior material for a vehicle, a vehicle capable of reducing the manufacturing cost can be realized as compared with the case where a non-woven fabric or the like is provided on the hinge portion so as to cover the cross section of the base material to prevent the plate portions from hanging down. Interior materials can be provided.

In the above configuration, the vehicle interior material is a luggage board laid in the luggage compartment of the vehicle with one surface side facing downward, and the second plate portion is arranged in front of the first plate portion. At the same time, it can be bent upward with respect to the hinge portion so as to be in contact with the rear side of the seat provided on the vehicle. According to such an interior material for a vehicle, when a worker who manufactures a vehicle grasps the first plate portion and lays the luggage board in the luggage compartment with the back surface side facing downward, for example, the second plate portion. Can be laid smoothly in the room without hanging down and getting caught on the floor surface or other members, and without the second plate part bending downward with reference to the hinge part and coming into contact with the rear side of the seat. ..
