[0002]
[Prior art]
Many junior seats for vehicles are provided on the market in order to raise the sitting position of a child sitting in a car seat so that a seat belt provided in the car can be used. When the body of the child is large, the body of the child sitting on the junior seat can be restrained by a seat belt provided in the vehicle.
[0003]
In the case of an infant with a small body, a child seat is fixedly attached to a car seat using a seat belt provided in the car, and the infant's 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 desired to provide a comfortable environment for a child seated in the vehicle child seat as described above. Since the child's buttocks are in pressure contact with the seat surface of the child seat, hot air or moisture tends to stay between the buttocks and the seat surface. Such hot air and moisture may cause discomfort to the child and may harm the health of the child.
[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]
Vehicular child seat in accordance with the invention, a seat base having a plurality of grooves extending from the rear end to the forward end to the surface, is placed on the seat base has a plurality of through holes communicating with the respective grooves The front end portion of the seat base has a downwardly inclined surface inclined downward, and the forward end portion of the cushion material has an upwardly inclined surface inclined upward; between the upper inclined surface of the lower inclined surface and the cushion member, it forms an air inlet for introducing air into the groove of the a progressively form the opening area increases toward the front.
[0007]
The cushioning material laid under the butt repeats compression and expansion according to the movement of the child seated on the child seat. This compression and expansion of the cushion material creates a flow of air that passes through the through hole of the cushion material and the groove of the seat base. This air flow acts to remove heat and moisture between the child's buttocks and the seating surface, so that a comfortable environment can be given to the child.
[0008]
Further, according to the child seat for a vehicle according to the present invention, the seat base has a plurality of grooves extending from the rear end to the front end, and the cushion material has a plurality of through holes communicating with the respective grooves. Have. With such a configuration, the effect of removing hot air and moisture can be further enhanced.
[0009]
Preferably, the child seat for a vehicle 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 that has an opening corresponding to the air intake port, penetrating in the front-rear direction at the front end thereof. In the present invention, since air intakes are formed at the front end of the seat base and the front end of the cushioning material, if the air intake has a large opening area, there is a risk that a child will insert a finger into the air intake. There is. In order to avoid such a risk, it is desirable to provide the frame member as described above. In one embodiment, the frame member has a lattice shape.

DETAILED DESCRIPTION OF THE INVENTION
1 to 4 show an embodiment of the present invention. The illustrated vehicle child seat 1 is called a junior seat and is suitable for use by a large-body child. It is described in advance that the present invention is applicable not only to the junior seat but also to a child seat suitable for use by infants with small bodies.
[0011]
The child child seat 1 includes a seat base 10 shown in FIG. 3, a cushion material 20 shown in FIG. 4, and a cover member 30 that covers the front end of the seat base 10 and the cushion material 20.
[0012]
As shown in FIG. 3, the seat base 10 has a plurality of grooves 11 extending from the rear end to the front end on the surface. In the illustrated embodiment, five rows of grooves 11 are formed.
[0013]
As shown in FIGS. 2 and 4, the cushion material 20 disposed on the seat base 10 has a plurality of through holes 21 communicating with the respective grooves 11 of the seat base 10. In the illustrated embodiment, the cushion 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 cushion member 20 is tapered upward. The surface has a shape. Therefore, an air intake port is formed at the front end of the seat 1 such that the opening area gradually increases toward the front.
[0015]
An opening is formed in the front end portion of the cover member 30 at a portion corresponding to the air intake port, 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]
The child sitting on the child seat 1 moves frequently. Since the position of the buttocks shifts as the child moves, the cushion material 20 in contact with the buttocks repeats compression and expansion. This air flow acts to remove the heat and moisture between the child's buttocks and the seating surface. A large tapered opening air intake at the front end of the seat 1 facilitates the entry and exit of air.
[0017]
Due to the presence of the frame member 31 attached to the front end of the cover member 30, it is possible to avoid the risk that the child inserts his / her finger into the air intake.
[0018]
As mentioned above, although one Embodiment of this invention was described with reference to drawings, this invention is not limited to the thing of the form shown in figure. Various modifications and variations can be made to the illustrated embodiment within the same range or equivalent range as the present invention.
