Description

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a child seat for a vehicle which is used by being placed on a vehicle seat. The child seat for a vehicle includes both a junior seat suitable for use by a child with a large body and a child seat suitable for use by a baby with a small body.
[0002]
[Prior art]
Many vehicular junior seats are available on the market to increase the sitting height of a child sitting in a vehicle seat so that the vehicle's seat belt can be used. When the child's body is large, the child's body sitting on the junior seat can be restrained by a seat belt provided in the vehicle.
[0003]
In the case of an infant having a small body, the child seat is fixedly attached to the car seat using a seat belt provided in the car, and the infant body is restrained by, for example, a five-point seat belt provided in the child seat.
[0004]
[Problems to be solved by the invention]
It is desirable to provide a comfortable environment for a child sitting on the above-described vehicle child seat. Since the buttocks of the child are pressed against the seat surface of the child seat, hot air or moisture tends to stay between the buttocks and the seat surface. Such heat and moisture may cause discomfort to the child and may impair the child's health.
[0005]
An object of the present invention is to provide a child seat for a vehicle that can provide a comfortable environment for a child.
[0006]
[Means for Solving the Problems]
A child seat for a vehicle according to the present invention includes a seat base having a groove extending to a front end on a surface thereof, and a cushion material disposed on the seat base and having a through hole communicating with the groove.
[0007]
The cushioning material laid under the buttocks repeatedly compresses and expands according to the movement of the child's body sitting on the child's seat. Due to the compression and expansion of the cushion material, an air flow is generated through the through holes of the cushion material and the grooves of the seat base. This air flow acts to remove hot air and moisture between the buttocks and the seating surface of the child, thereby providing a comfortable environment for the child.
[0008]
Preferably, the seat base has a plurality of grooves extending to a front end thereof, and the cushioning material has a plurality of hole rows aligned along each of the above-mentioned grooves. With such a configuration, the effect of removing hot air and moisture can be further enhanced.
[0009]
Preferably, the vehicle child seat further includes a cover member that covers the front end of the seat base and the cushion material. The cover member includes a frame member having an opening penetrating in the front-rear direction at a front end thereof. It is desirable to provide an air intake at the front end of the seat base and at the front end of the cushioning material, but if the air intake has a large opening area, there is a risk that a child may insert a finger into the air intake. In order to avoid such a risk, it is desirable to provide the above-mentioned frame member. In one embodiment, the frame member has a lattice shape.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
1 to 4 show an embodiment of the present invention. The illustrated child seat 1 for a vehicle is called a junior seat, and is suitable for use by a child with a large body. It is noted in advance that the present invention is not only applied to junior seats, but is also applicable to child seats suitable for use by small infants.
[0011]
The vehicle child seat 1 includes a seat base 10 shown in FIG. 3, a cushion member 20 shown in FIG. 4, and a cover member 30 that covers the front end of the seat base 10 and the cushion member 20.
[0012]
As shown in FIG. 3, the seat base 10 has a plurality of grooves 11 on its surface extending from its rear end to its front end. In the illustrated embodiment, five rows of grooves 11 are formed.
[0013]
As shown in FIGS. 2 and 4, the cushion member 20 disposed on the seat base 10 has a plurality of through holes 21 communicating with the grooves 11 of the seat base 10. In the illustrated embodiment, the cushioning material 20 has five rows of holes aligned along each groove 11.
[0014]
As is apparent from FIG. 2, the front end portion 10a of the seat base 10 has a tapered surface inclined downward, and the front end portion 20a of the cushioning material 20 has a tapered surface inclined upward. It has a surface of a shape. Therefore, at the front end of the seat 1, there is formed an air intake port whose opening area gradually increases toward the front.
[0015]
An opening is formed in a front end portion of the cover member 30 at a portion corresponding to the air intake, and a frame member 31 is attached to the opening portion. The frame member 31 has an opening 31a penetrating in the front-rear direction. In the illustrated embodiment, the frame member 31 has a lattice shape.
[0016]
A child sitting on the child seat 1 moves frequently. Since the position of the buttocks shifts with the movement of the child's body, the cushion material 20 in contact with the buttocks repeatedly compresses and expands. This air flow acts to remove hot and moisture between the child's hips and the seat. A large tapered opening air intake at the front end of the seat 1 facilitates the ingress and egress of air.
[0017]
Due to the presence of the frame member 31 attached to the front end of the cover member 30, the danger of a child inserting a finger into the air intake can be avoided.
[0018]
The embodiment of the present invention has been described with reference to the drawings. However, the present invention is not limited to the illustrated embodiment. Various modifications and variations can be made to the illustrated embodiment within the same or equivalent scope as the present invention.
