  By the way, although the vehicle seat described in Patent Document 1 is provided with the armrest standing upward from the side part of the seat cushion, the part standing up from the side part of the seat cushion includes the components in the seat cushion. Since the interlocking functional parts and the like are not built in, it is possible to adopt a structure in which the entire armrest is formed in a large block shape and the whole is removed as it is. However, in the case where functional parts that are interlocked with the parts in the seat cushion are arranged in the standing wall, the standing wall has to be integrated with the seat cushion.

In such a vehicle seat, the buckle of the seat belt device is connected to the vehicle body below the seat by an anchor strap, and is pulled out from the gap between the seat cushion and the standing wall to the upper side of the seat cushion. The occupant seated on the seat connects the tongue plate on the webbing side to the buckle on one side of the seat cushion when wearing the webbing.
However, for example, when a relatively large child seat called a booster seat is mounted on the seat cushion, the gap between the child seat and the standing wall becomes narrow, and it is difficult to connect the buckle when the webbing is mounted. Become.

  Therefore, the present invention easily attaches the tongue plate on the webbing side to the buckle pulled out from between the seat cushion and the standing wall, even if the side wall of the seat cushion is provided with the standing wall that also supports the armrest. An object of the present invention is to provide a vehicle seat that can be used.

The vehicle seat according to the present invention employs the following configuration in order to solve the above problems.
The invention according to claim 1 is a seat cushion (for example, the seat cushion 8 according to the embodiment) on which an occupant sits, and a standing wall (for example, the standing wall 11 according to the embodiment) that rises upward from a side portion of the seat cushion. An armrest (for example, the armrest 12 of the embodiment) placed on the upright wall and on which an occupant's arm is placed, and a buckle of a seatbelt device connected to a vehicle body side below the seat cushion ( For example, in the vehicle seat in which the buckle 22) of the embodiment is pulled out above the seat cushion from between the seat cushion and the standing wall, a buckle mounting space is provided on the side of the standing wall facing the seat cushion. A recess (for example, the recess 48 of the embodiment) is provided, and the armrest is configured to And it is characterized in that it the attached to the standing wall to cover at least the upper parts.
Accordingly, when the tongue plate on the webbing side is attached to the buckle, it is possible to insert a hand into the concave portion on the side portion of the standing wall and perform the attaching operation of the tongue plate there. For this reason, for example, even when a booster seat is attached on the seat cushion, the tongue plate can be easily attached to the buckle.

The invention according to claim 2 is characterized in that, in the vehicle seat according to claim 1, the armrest is attached to the upright wall so as to be displaceable.
In this case, when the tongue plate is mounted on the buckle, the mounting operation of the tongue plate can be further facilitated by appropriately displacing the armrest with respect to the standing wall.

The invention according to claim 3 is the vehicle seat according to claim 1 or 2, wherein the armrest is attached to the upright wall so as to be slidable up and down.
In this case, when the tongue plate is attached to the buckle, the armrest can be appropriately slid up and down with respect to the standing wall.

The invention according to a fourth aspect is the vehicle seat according to any one of the first to third aspects, wherein the armrest is detachably attached to the upright wall. .
In this case, for example, when the booster seat is installed on the seat cushion and used, by removing the armrest from the standing wall, the tongue plate can be easily attached to the buckle.

  According to the present invention, since the recessed portion that forms the buckle mounting space is provided on the side portion of the standing wall facing the seat cushion, the standing wall that also serves as the support for the armrest is provided on the side portion of the seat cushion. Although it is a structure, the tongue plate on the webbing side can be easily attached to the buckle.

  As shown in FIG. 7, in the seat 2 </ b> B, a plate-like slide base 24 is slidably supported on a seat rail 23 (lower rail) laid on the vehicle body floor 20, and a rotating hinge 25 is mounted on a front end portion of the slide base 24. The front end portion of the seat cushion 8 is connected to be able to turn back and forth. A seat back 9 is rotatably connected to the rear end portion of the seat cushion 8 via a reclining mechanism 26. Further, a tumble striker 27 made of a substantially U-shaped bar-like member protrudes from the rear end portion of the slide base 24, and a lock mechanism 28 provided at the lower end of the rear portion of the seat back 9 engages with the tumble striker 27. It is like that.

The reclining mechanism 26 is released by operating either a reclining release lever 33 provided at the side of the seat cushion 8 or a reclining release strap 34 provided at the rear end of the standing wall 11 below the armrest 12. It is like that.
In addition, when the reclining mechanism 26 is released, the seat back 9 rotates about the rotation shaft 26a of the reclining mechanism 26 and transitions to a two-stage forward tilted state. That is, the seat back 9 is in a half-tilt state in which it is tilted forward about half before the tumble operation is completed, and then in a full-tilt state in which the seat back 9 is tilted until it overlaps with the seat cushion 8. A semi-falling stopper 31 is provided at the rear end portion of the seat cushion 8, and when the reclining mechanism 26 is released, the stopper pin 32 on the seat back 9 side comes into contact with the half-falling stopper 31.
