However, in the case of the rear seat having the above structure, when the foot is placed on the ottoman, the load of the ottoman and the foot placed on the ottoman is concentrated on the hinge portion, so that the ottoman is held in the horizontal position. In order to do so, it is necessary to provide a highly rigid holding mechanism at the hinge portion. Therefore, there is a drawback that the hinge portion becomes large. Also,
Since the load is concentrated on the hinge portion as described above, the width dimension of the ottoman in the front-rear direction cannot be increased, and the footrest is insufficient.

Therefore, an object of the present invention is to provide an ottoman device for an automobile seat, which can reduce the load on the hinge portion of the ottoman and maintain a stable horizontal posture. Another object of the present invention is to provide an ottoman device for an automobile seat, which can be used for various purposes.

In order to achieve the above object, the present invention rotatably connects a rear end portion of an ottoman to a front portion of a seat cushion so that the ottoman is horizontally level with substantially the same height as the seat cushion. In an automobile seat that is rotatable between a position and a downward position that is rotated downward of a seat cushion, a foldable leg is provided on the back surface of the ottoman to rotate the ottoman to a horizontal position. In addition, by erecting the legs with respect to the ottoman, the tip ends of the legs can be supported by the floor.

The ottoman can be supported in the horizontal position by rotating the ottoman to the horizontal position, erecting the legs provided on the back surface of the ottoman, and bringing the tips of the legs into contact with the floor. In this horizontal position, even if a large downward load is applied to the Ottoman, since the load is supported by the legs, an excessive moment is not applied to the hinge portion of the Ottoman. Further, since it is not necessary to provide a lock mechanism for holding the ottoman in the hinge portion in a horizontal posture,
The hinge portion can be made small and have a simple structure. Also, if you fold the legs and rotate the ottoman downwards,
The ottoman can be in the down position. Therefore, the ottoman does not get in the way when getting on and off.

A locking mechanism is provided at the rear end portion of the ottoman so as to project vertically, and a connecting hole into which the stay can be inserted is provided in the front portion of the seat cushion, and a locking mechanism for preventing the stay from coming off in this connecting hole. Is desirable. In this case, the ottoman can be easily separated from the seat cushion by releasing the lock mechanism and pulling out the stay from the connecting hole. Further, when the ottoman is rotated to the downward position with the stay inserted in the connecting hole, the stay is prevented from coming off by the lock mechanism, so that the ottoman does not drop from the seat cushion.

It is desirable to provide foldable legs at the front and rear ends of the back of the ottoman. In this case, since the ottoman can be stably supported by the front and rear legs, the ottoman can be taken out of the vehicle and used as a bench.

If a slide mechanism is provided at the connecting portion between the ottoman and the seat cushion so that the ottoman can slide in the vehicle width direction, for example, a space where the ottoman can be seated in a normal posture can be secured while the ottoman is retained in the remaining space. They can be arranged, and the degree of freedom of arrangement is increased.

If the legs provided on the back surface of the ottoman can be expanded and contracted and the front end portions of the legs are brought into contact with the floor under the seat cushion in a state where the legs are shortened, the ottoman can be held in the forward leaning position. It can be used as a footrest. If you use this together with reclining the seat back, you can take an ideal comfortable posture.
