DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a child seat mounted on a vehicle seat, and more particularly to a child seat to be taken out of a vehicle and used as a stroller.

[0002]

2. Description of the Related Art Conventionally, when an infant is to ride in a car, a child seat is placed on a vehicle seat and seated thereon. A child seat that can be taken out of the car and used as a stroller has also been devised.
As disclosed in Japanese Patent No. 38, a plurality of retractable wheels are provided on the bottom surface of the child seat. This type of child seat is taken out of the vehicle and each wheel is set to a use position in a standing posture to form a stroller. Then, when placing the vehicle on the vehicle seat, each wheel is stored in a laid-down state along the seat bottom of the child seat, and is placed on the vehicle seat via a plate receiving the seat bottom integrally with the stored wheels. As a result, the vehicle seat is not stained with mud or the like attached to the wheels.

[0003]

However, when the child seat is placed on a vehicle seat or taken out of the vehicle to be used as a stroller, the base plate must be attached and detached each time, which is not convenient. Generally, a stroller is required to have a small case for storing diapers, clothes, and the like, but a child stroller does not have a small case when used as a stroller, so that it is not easy to use as a stroller. Therefore, the present invention does not require the detachment of a separate member such as the above-mentioned base plate when mounting on a vehicle seat or taking it out of the vehicle as a stroller, and is convenient with a small case when the stroller is used. An object of the present invention is to provide a child seat that is also used as a stroller.

[0004]

SUMMARY OF THE INVENTION The present invention relates to a child seat which is removably mounted on a seating surface of a vehicle seat, has a retractable wheel on the seat bottom surface, and takes the child seat out of the vehicle and uses it as a stroller. In the child seat, a cover member of a container body that is slidable in the front-rear direction along the seat bottom surface and is slidable along the seat bottom surface and covers the seat bottom surface with the wheels stored is provided, and the cover member is pulled out rearward and the wheel As a stroller in a standing posture, and the accessory member of the stroller is constituted by the cover member drawn backward (claim 1).

The above-mentioned cover member is provided with slide portions in the front-rear direction at the upper edges of the left and right side walls, respectively, and both slide portions slide on rail members provided in the front-rear direction along the left and right side edges of the seat bottom surface of the child seat. The cover member is movably supported so that the cover member can be moved between a front position covering the seat bottom surface and a rear position projecting rearward from the seat bottom surface.

According to the first and second aspects of the present invention,
When placing the cover member on a vehicle seat or taking it out of the vehicle as a stroller, the cover member may be slid rearward or forward to make it convenient. In addition, since the cover member that is pulled out rearward when a stroller is used as a small case, the convenience as a stroller is also good.

[0007] The wheel is provided at the tip of the support leg, and a plurality of wheels are provided at front and rear positions of the seat bottom, respectively.
The front wheels support the support legs on the seat bottom surface so as to be able to move up and down, and the rear wheels support the support legs on the seat bottom surface so as to be movable up and down. According to this, the front wheels and the rear wheels do not overlap when the wheels are stored, and the wheels can be efficiently stored on the seat bottom surface.
