Patent Document 1 has a configuration in which the upper portion of the backboard is sewn to the seat cover and the lower portion is pulled by a spring on the side of the seat cushion, even when the inclination of the seat back is changed with respect to the seat cushion. A configuration is shown in which the backboard does not sag with respect to the seat back due to the action of the spring on the side of the seat cushion.

As a result, in the configuration described in Patent Document 1, the surface of the resin member obtained by molding the rear surface of the seat plate from top to bottom is covered with a backboard formed by covering the surface of the resin member with a skin material such as leather, woven fabric, or non-woven fabric. The space under the boarding difference seated in the back seat is made as wide as possible.

However, because the part that the passenger's shoes of the backseat may touch is also made of a resin member covered with a relatively thin skin material, the shoes do not slip easily when touched by the shoes, and the backseat It may make the passenger feel worse.

On the other hand, the configuration described in Patent Document 2 has a configuration in which a portion from the lower end of the backboard to the bottom of the seat cushion where the shoes of the passengers in the rear seat may touch is covered with a carpet. This makes it possible to improve the slipperiness of the shoes when they are touched and improve the feel of the passengers in the back seats.

However, in the configuration described in Patent Document 2, the carpet is used alone, and there is no member for supporting the carpet on the back side. Therefore, when the shoes of the passenger in the rear seat touch, the shoes touch the carpet. Only the part may be deformed and spoil the appearance of the carpet.

Further, in the configuration described in Patent Document 2, the upper end portion of the carpet is fixed to the seat back side, and the lower end portion is locked to the seat cushion, and the side surfaces on both sides of the carpet are the seat back. And it is not fixed to any of the seat cushions and is free.

In such a configuration, when the reclining mechanism is operated to change the inclination of the seat back with respect to the seat cushion, the lower end is locked to the seat cushion from the position fixed to the seat back side of the upper end of the carpet. Since the length to the seated position changes, depending on the inclination of the seat back, the carpet may slacken with respect to the seat cushion and the seat back, creating a gap, which may worsen the appearance.

The present invention solves the above-mentioned problems of the prior art and creates a gap between the seat back and the carpet even when the reclining mechanism is operated to change the inclination of the seat back with respect to the seat cushion. It is intended to provide a vehicle seat that can prevent the appearance from being deteriorated.

In order to solve the above-mentioned problems, in the present invention, in a vehicle seat provided with a seat cushion, a seat back, and a headrest, the seat back has a seat back skin covering the surface, and the seat back of the seat back skin has a seat back. The side covering the back surface has a back side trim cover, a backboard, and a sagging portion, and the back side trim cover, the backboard, and the sagging portion are sewn and connected to each other.

According to the present invention, the space between the back side trim cover arranged on the back surface of the seat back and the sagging portion can be sealed, and even if the inclination of the seat back with respect to the seat cushion is changed by the reclining mechanism, the space between the back side trim cover and the sagging portion is changed. It is possible to prevent the appearance of the seat back from being spoiled by eliminating the gaps in the seat back.

In addition, since there is no gap between the back side trim cover and the sagging part, the passenger's fingers do not get in between the back side trim cover and the sagging part, and the fingers are caught between the mechanical parts and injured. Can be prevented.
