  In general, a vehicle seat is divided into a seat cushion and a seat back, and the vehicle seat is roughly divided into those that do not tilt in the front-rear direction. In the type in which the seat back tilts in the front-rear direction, a reclining device is provided. However, when the seat back tilts in the front-rear direction, the peripheral portion of the reclining device of the seat cushion may interfere with the reclining device and be pushed up. Then, wrinkles occur in the skin of the base portion of the interfering area (interference part) in the seat cushion, and there is a concern that the appearance (aesthetics) may be deteriorated or the occupant may feel uncomfortable.

  However, Patent Document 1 focuses only on covering the notch formed in the seat cushion. For this reason, when it is the structure of patent document 1, when a seat cushion is pushed up by interfering with a reclining apparatus or a reclining cover, the free end side will be pushed up together and the band-shaped member will be turned up. Then, wrinkles generated on the skin of the seat cushion are exposed. Therefore, the technique of Patent Document 1 cannot solve the problem that occurs when the seat back is tilted, and still has room for improvement.

  In view of such a problem, the present invention can make it difficult for the occupant's eyes to touch wrinkles generated on the skin of the seat cushion when the seat back is tilted back and forth, ensuring good appearance and occupant comfort. An object of the present invention is to provide a vehicle seat that can be used.

  In order to solve the above-described problems, a typical configuration of a vehicle seat according to the present invention is connected to a seat cushion and a rear end portion of the seat cushion via a reclining mechanism, and can tilt in the front-rear direction with respect to the seat cushion. In a vehicle seat comprising: a seatback; a reclining cover that covers a connecting portion of the reclining mechanism; and a notch that is formed longitudinally in the vehicle front-rear direction on the vehicle width direction center side of the rear portion of the seat cushion and accommodates a seatbelt buckle The vehicle seat includes a belt-like member having one end attached to the upper end portion of the inner wall on the outer side in the vehicle width direction of the notch and the other end attached to the side surface on the vehicle width direction center side of the seat cushion. It is made of the same material as the cushion skin, and the notch extends in the vehicle width direction from the upper end of the inner wall outside the notch in the vehicle width direction. A cover portion covering the upper surface of the seat cushion, and an elastic portion made of a stretchable material and connected to an end portion on the vehicle width direction center side of the cover portion from the vehicle width direction center side surface of the seat cushion. It is characterized by.

  In the above configuration, the belt-like member attached to the seat cushion includes a covering portion made of the same material as the skin of the seat cushion and an elastic portion made of a stretchable material. Since the notch formed in the seat cushion is covered with the covering portion, the notch can be difficult to touch the occupant's eyes.

  Here, when the seat back is tilted back and forth, the part of the seat cushion that is closer to the center in the vehicle width direction than the notch is pushed upward by interfering with the reclining cover, so that the skin of the seat cushion is wrinkled. May occur. At this time, in this embodiment, even if a portion of the seat cushion closer to the vehicle center than the notch (a portion from the vicinity of the front end of the notch to the rear end of the seat cushion in the vehicle front-rear direction) is pushed up, Since one end is attached to the inner wall of the notch and the other end is attached to the side surface of the seat cushion, it does not turn up.

  Particularly in the present embodiment, when a portion (interference portion) of the seat cushion that interferes with the reclining cover is pushed up, an elastic portion positioned on the side surface of the seat cushion extends in accordance with the movement of the seat cushion. Thereby, since the covering portion can follow the movement of the seat cushion, it is possible to suitably hide the wrinkles generated on the upper surface of the base portion of the interference portion of the seat cushion while covering the notch. Therefore, it is possible to ensure good appearance and passenger comfort.

  In order to solve the above-mentioned problems, another configuration of the vehicle seat according to the present invention is connected to the rear end portion of the seat cushion via the seat cushion and the reclining mechanism, and can tilt in the front-rear direction with respect to the seat cushion. In a vehicle seat comprising: a seat back; a reclining cover that covers a connecting portion of the reclining mechanism; and a notch that is formed in a longitudinal direction in the vehicle front-rear direction on the vehicle width direction center side of the rear portion of the seat cushion and accommodates a seat belt buckle. The vehicle seat includes a belt-like member having one end attached to the upper end portion of the inner wall on the outer side in the vehicle width direction of the notch and the other end attached to the side surface on the vehicle width direction center side of the seat cushion, and the notch of the notch in the seat cushion. A longitudinal slit in the vehicle front-rear direction formed at the center portion in the vehicle width direction. The cover is made of the same material as the skin of the car and covers the upper surface of the seat cushion across the notch from the upper end of the inner wall on the outside in the vehicle width direction. It has an elastic part connected with the inside of the side by the side of the vehicle width direction center side of a seat cushion via a slit from the end part of the vehicle width direction center side.

  According to this structure, an elastic part is arrange | positioned inside a seat cushion through a slit, ie, by being inserted in a slit, among strip | belt-shaped members. As a result, the elastic portion can be made difficult to touch the occupant's eyes, and thus the appearance can be further enhanced while obtaining the same effects as the above-described vehicle seat.

  The belt-like member may further include an extension portion that extends from a region of the covering portion that overlaps the reclining cover when viewed from the vehicle front-rear direction to a position that contacts the reclining cover. Thereby, the wider area | region of the upper surface of a seat cushion can be covered. Therefore, the wrinkles generated on the upper surface of the seat cushion can be more suitably hidden, and the appearance can be further improved. Further, since the extension portion is extended to a position where it comes into contact with the reclining cover, it is possible to prevent the passenger from contacting the reclining cover.

  According to the present invention, when the seat back is tilted back and forth, it is possible to make it difficult for the occupant's eyes to touch the wrinkles generated on the skin of the seat cushion, and it is possible to ensure good appearance and occupant comfort. A vehicle seat can be provided.
