DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a child seat fixed to a vehicle seat with a seat belt, and more particularly to a child seat for an infant to be seated while lying down.

[0002]

2. Description of the Related Art Since a child seat for an infant cannot be seated alone, the infant is generally held in a cradle-shaped seat body in a lying state.
When a child seat is fixed to a vehicle seat by a seat belt, there is a child seat in which a waist belt portion of the seat belt is traversed over a seat body to be fixed. However, the length of the seat belt varies depending on the type of the vehicle, and there are some vehicles in which the child seat cannot be fixed to the seat because the length is insufficient when the waist belt portion is passed over the seat body. In addition, in such a child seat, when the baby is put on and off, the waist belt portion passing over the upper part of the seat body becomes an obstacle, so the seat belt must be removed every time the baby is put on and off. Is inconvenient. For this reason, an infant child seat generally has a structure in which a waist belt portion is passed through a lower portion of a seat body. FIG. 6 shows an example of such a child seat.

In FIG. 6, a child seat 10 for an infant has a cradle-shaped seat body 12 serving as a seating portion. The baby (not shown) is to be seated on the seat body 12 in a laid state, with the baby's feet facing the front end 14 of the seat body 12 and the head facing the rear end 16. It has become. A pedestal portion 18 is provided integrally below the center of the seat body 12.
In the seat body 12, an arch-shaped carry handle 20 is pivotably attached to the center in the front-rear direction so that the child seat 10 can be easily carried through the carry handle 20. It is.

[0004] The child seat 10 is usually arranged in the rear seat of the vehicle with the front end 14 facing the rear of the vehicle, that is, with the front end 14 facing the back of the rear seat and the rear end 16 facing the front seat. The seat is fixed by a seat belt (not shown). For this reason, the front end 1 of the seat body 12 is
On the fourth side, a slit-shaped waist belt passing portion 22 is formed. One end of the waist belt passing portion 22 communicates with an insertion groove 24 extending vertically, and the lower end of the insertion groove 24 crosses the pedestal portion 14 and opens on the lower surface of the pedestal portion 14.
A projection 26 is provided at the boundary between the waist belt passing portion 22 and the insertion groove 24 to prevent the waist belt portion engaged with the waist belt passing portion 22 from falling out of the waist belt passing portion 22. are doing.

[0005] A shoulder belt passing portion 28 is provided on the lower surface on the rear end 16 side of the seat body 12, and a shoulder belt portion of the seat belt is engaged with the shoulder belt passing portion 28. Further, a belt fixing device 30 is attached to the seat body 12 at a position corresponding to the shoulder belt passing portion 28. The belt fixing device 30 is used for the seat body 1.
2 and the finger hooks 34, 34 are operated so as to approach each other to release the engagement with the seat body 12 and rotate as shown by the arrow 36. Thus, the belt groove 32 can be opened.

In the conventional infant child seat 10 constructed as described above, the rear end 16 of the seat body 12 is arranged in the rear seat with the rear end 16 facing the front seat side of the vehicle, and the waist belt portion of the seat belt is lumped. After engaging with the belt portion 22 and engaging the shoulder belt portion with the shoulder belt passing portion 28, the front end side of the belt fixing device 30 is locked to the seat main body portion 12, thereby being fixed to the rear seat.

[0007]

By the way, in the conventional infant child seat 10, a pedestal portion 14 is provided at a lower portion of the seat body portion 12 on which the infant is laid down.
It is formed integrally. For this reason, the air permeability of the seat body is very poor, and it is difficult to seat the baby in a comfortable state.

Also, a conventional infant child seat 10 is provided.
When the waist belt portion is passed through the waist belt passing portion 22 to fix the child seat 10, the child seat 10
Since it is necessary to pass the waist belt portion through the insertion groove 24 opened on the lower surface of the child, the child seat 10 must be lifted, and not only can the infant be seated but also the fixing operation is troublesome. . Also, when the shoulder belt portion of the seat belt is engaged with the shoulder belt passing portion 28, the rear end 16 of the child seat 10 must be lifted or shifted in the left-right direction because the front seat becomes an obstacle. . Moreover, since the shoulder belt portion needs to be turned over the seat body portion 12 and hung on the shoulder belt passage portion 28, if the length of the seat belt is not sufficient,
The child seat 10 cannot be fixed to the seat.

Further, since the waist belt passing portion 22 is formed in a narrow slit shape, the buckle for connecting the tongue attached to the seat belt is long,
If the buckle is not in the side of the seat but in the seat,
The tongue hits the side surface of the child seat 10, and the waist belt portion passing through the waist belt passing portion 22 is slackened, so that the child seat 10 cannot be completely fixed.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned drawbacks of the prior art, and has as its object to obtain good air permeability. Another object of the present invention is to enable the seat belt to be easily fixed to a seat.

It is a further object of the present invention to enable the vehicle to be fixed to a seat regardless of the type of vehicle. An object of the present invention is to make it possible to easily carry a baby on and off.

Can be given. And it is more preferable to form a ventilation hole in the lower part of the seat body. In addition, since the front and rear portions of the seat body are supported by the support table, the seat body can be firmly fixed to the vehicle seat without lack of stability.

The gap is made large enough to allow the tongue of the seat belt to pass therethrough, and a shoulder belt passing portion for engaging the shoulder belt portion of the seat belt is formed on the rear side of the lower surface of the seat body to form a gap for the support base. When the waist belt pass-through portion for engaging the waist belt portion of the seat belt is formed on the front side of the surface where the vehicle is, the tongue of the seat belt is connected to the buckle through the gap when fixing the child seat to the seat. Then, it is only necessary to engage the waist belt portion with the waist belt passage portion provided on the support base and the shoulder belt portion with the shoulder belt passage portion provided on the seat body portion, and fix the child seat to the vehicle seat. In this case, there is no need to lift or shift the child seat in the left-right direction, and the child seat can be easily fixed in a state where the baby is placed thereon. In addition, since the shoulder belt portion can be engaged with the shoulder belt passage portion in a state where it passes through the gap, it is not necessary to pass above the seat body portion. Can also be fixed securely.

Further, since a gap is formed between the seat body and the support table, the gap having a size that allows the tongue of the seat belt to pass therethrough. Even if the tongue is not provided on the side but in the seat, the tongue does not catch on the support base or the seat body, causing the waist belt to loosen, and it can be securely fixed to the seat. it can. And, since both the waist belt portion and the shoulder belt portion are located below the seat body portion, the seat belt does not become a hindrance when the baby is put on and off, and there is no need to remove the seat belt. In addition, the baby can be easily loaded and unloaded.
