In order to solve the above-mentioned problems, the invention according to claim 1 covers a seat structure having a frame and a pad with a skin cover that covers the outside of the seat, and includes a cover for the skin cover. In a vehicle seat having a terminal portion fixed to the seat structure, a locked portion for fixing a terminal portion of the skin cover is provided on the seat structure, while a terminal portion of the skin cover is provided on the terminal portion of the skin cover. In this configuration, a locking piece fixed to the locked portion by hooking is provided, and lock release means for releasing the locking of the locking piece is provided.

According to the first aspect of the present invention, by operating the lock releasing means, the lock of the skin cover can be released from the seat structure and the cover can be easily removed. Therefore, when recycling the material of the vehicle seat, the skin cover is easily separated, which is convenient. Furthermore, since the locking release means is provided at the end of the skin cover where the locking piece is located, the locking release is easy when the sheet is disassembled, but the state in which the sheet is normally used Then, the lock cannot be released easily. That is, since the terminal portion and the locking piece portion of the skin cover are provided at a location hidden from a normal user, such as the back bottom of the seat, the locking release means is also hidden from the normal user. Arrangement. Therefore, based on the recycling request,
A configuration that allows the operator to easily release the lock during disassembly,
It is possible to satisfy both a condition necessary for a vehicle seat and a structure in which a normal user cannot easily release the lock.

Specifically, as in the second aspect of the present invention, the unlocking means according to the first aspect can be configured as a belt-shaped member that unlocks the locking piece by pulling. Since the unlocking means is a belt-shaped member that works by pulling, even if a normal user touches the hand by mistake, the lock does not come off, and the conditions necessary for the vehicle seat can be more reliably determined. Can be. Here, in the configuration in which the locking piece is unlocked by the band-shaped member, for example, the shape of the locking piece is elastically deformed by pulling to unlock the locking piece. Alternatively, the locking piece may be inserted between the locking piece and the locked part during locking, and may be pulled to separate the locking piece and the locked part.
