Description

The present invention relates to a trim cover and an interior product for a vehicle.

The seat back of a vehicle seat mounted on a vehicle such as an automobile includes a cushion pad and a trim cover that covers the cushion pad. The trim cover is formed in a bag shape having an opening, and the opening of the trim cover is typically arranged on the rear surface side at the lower end of the seat back. In this case, the terminal portion of the front skin material of the trim cover is routed around the lower end portion of the seat back to the rear surface side. Then, the end portion of the rear surface skin material of the trim cover is overlapped on the outside of the terminal portion of the front surface skin material. A hook having a J-shaped cross section as a locking member is sewn to the terminal portions of the front skin material and the rear skin material, and both terminal parts are connected by engaging the J hooks of both terminal parts with each other. The opening of the trim cover is closed (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2011-45622

In the mounting structure of the locking member described in Patent Document 1, the corners of both ends of the J hook sewn to the terminal portion of the front skin material of the trim cover in the longitudinal direction are slits formed in the front skin material. It is plugged into and covered with a front skin material. The terminal portion of the front skin material on which the slit is formed extends beyond the end portion of the J hook in the longitudinal direction, but this extending portion is not supported by the J hook and may hang down. If the extending portion of the front skin material hangs down, the appearance quality of the seat back is impaired.

Further, in order to cover the extending portion of the front skin material, the terminal portion of the rear surface skin material of the trim cover is also provided with an extending portion extending beyond the end of the J hook in the longitudinal direction. The existing part is also not supported by the J hook and may be rolled up. If the extending portion of the rear skin material is rolled up, there is a risk that internal objects such as cushion pads will be exposed. For example, by extending the extending portion of the front skin material beyond the J hook toward the terminal side, it is possible to suppress the exposure of the internal components, but the possibility that the extending portion of the front skin material hangs down increases.

The present invention has been made in view of the above circumstances, and an object of the present invention is to improve the appearance quality of interior parts for vehicles.

The trim cover of one aspect of the present invention is a bag-shaped trim cover having an opening, which is formed on an inner terminal portion and an outer terminal portion which are overlapped with each other to close the opening, and the outer terminal portion.
