Japanese Patent Application Publication No. 2001-30813 Japanese Patent Application Publication No. 2011-143737

In each of the above prior art technologies, both the seat cushion and the seat back must be stored, making storage operations cumbersome.

The present invention has been made in consideration of the above facts, and an object of the present invention is to obtain a vehicle seat that is easy to operate when stored.

A vehicle seat according to a first aspect includes a seat cushion on which a vehicle occupant sits, a seat back that supports the back of the vehicle occupant, a locking device that restrains an upper part of the seat back to a vehicle body, and a vehicle seat of the seat cushion that supports the vehicle body. a guide rail that is attached to the vehicle body at the rear and supports the lower end of the seat back so as to be movable in the longitudinal direction of the vehicle; While being folded forward, the lower end portion is guided by the guide rail and moved toward the rear of the vehicle, and is stored in the storage position of the seat cushion at the rear of the vehicle.

In the first aspect of the vehicle seat, an occupant of the vehicle sits on the seat cushion, and the occupant's back is supported by the seat back. The upper part of the seat back is restrained to the vehicle body by a locking device. A guide rail attached to the vehicle body behind the seat cushion supports the lower end of the seat back movably in the longitudinal direction of the vehicle. When the upper part of the seat back is released from being restrained by the locking device, the seat back is folded forward and the lower end is guided by the guide rail to be moved toward the rear of the vehicle, and is stored in the storage position of the seat cushion at the rear of the vehicle. With this vehicle seat, there is no need to store a heavy seat cushion, so the operation when storing the seat is easy.

The second aspect of the vehicle seat is the same as the first aspect, except that the seat cushion is fixed immovably to the vehicle body.

In the vehicle seat of the second aspect, since the seat cushion is immovably fixed to the vehicle body, the structure for attaching the seat cushion to the vehicle body is simple.

The third aspect of the vehicle seat is the first or second aspect, in which a roller that rolls within the guide rail is provided at the lower end of the seat back, and the roller can be recessed into a recess provided at the front end of the guide rail to enable the restraint by the locking device, and the roller can be removed from the recess to enable the movement of the seat back.

In the vehicle seat of the third aspect, a roller provided at the lower end of the seat back rolls within a guide rail. This roller enters a recess provided at the front end of the guide rail, allowing the upper part of the seat back to be restrained by the locking device. In this restrained state, the above-mentioned recess prevents the lower end of the seat back from being accidentally displaced. When the seat back is stowed, the above-mentioned roller comes out of the recess, allowing the seat back to move toward the rear of the vehicle.

The vehicle seat of the fourth aspect is configured in the third aspect such that the seat back is tilted forward and engaged with the seat cushion, so that the rollers come out of the recessed portion.

In the fourth embodiment of the vehicle seat, when the seat back is released from the upper restraint by the locking device and tilted forward, it engages with the seat cushion. This causes the rollers at the lower end of the seat back to come out of the recessed portion at the front end of the guide rail, allowing the seat back to move toward the rear of the vehicle. Therefore, no special operation is required to get the rollers out of the recessed portion.

The fifth aspect of the vehicle seat is any one of the first to fourth aspects, in which the front portion of the guide rail is vertically branched into an upper rail and a lower rail, and the locking device has an upper locking portion that restrains the upper portion of the seat back to the vehicle body when the lower end of the seat back is supported by the upper rail, and a lower locking portion that restrains the upper portion of the seat back to the vehicle body when the lower end of the seat back is supported by the lower rail.

In the vehicle seat of the fifth aspect, the front portion of the guide rail is vertically branched into an upper rail and a lower rail. When the lower end portion of the seat back is supported by the upper rail, the upper lock portion of the locking device restrains the upper portion of the seat back to the vehicle body. When the lower end portion of the seat back is supported by the lower rail, the upper portion of the seat back is restrained to the vehicle body by the lower lock portion of the locking device. Thereby, the arrangement height of the seat back can be changed depending on the physique of the occupant, for example.

The sixth aspect of the vehicle seat is any one of the first to fifth aspects, in which the seat back is divided into a left seat back and a right seat back, and includes the locking device and the guide rail for the left seat back, and the locking device and the guide rail for the right seat back.

In the vehicle seat of the sixth aspect, when the restraint of the upper part of the left seat back by the locking device for the left seat back is released, the left seat back is tilted forward and its lower end is guided by the guide rail for the left seat back, moved toward the rear of the vehicle, and stored in the storage position. When the restraint of the upper part of the right seat back by the locking device for the right seat back is released, the right seat back is tilted forward and its lower end is guided by the guide rail for the right seat back, moved toward the rear of the vehicle, and stored in the storage position. This allows the left seat back and the right seat back to be stored separately as needed.

In the vehicle seat according to a seventh aspect, in the first aspect or the second aspect, the storage position is set below the vehicle of a floor cover that constitutes a floor of a cargo compartment, and the vehicle seat of the seat back The floor cover is configured to be temporarily lifted upward of the vehicle by the seat back when moving rearward.

According to the seventh aspect of the vehicle seat, when the seat back moves toward the rear of the vehicle, the floor cover is temporarily lifted toward the upper side of the vehicle by the seat back. This allows the seat back to move to a storage position set for the floor cover below the vehicle. At this time, since the floor cover is lifted by the seat back, no special operation is required to lift the floor cover.

As explained above, the vehicle seat of the present invention is easy to operate when storing.
