Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a child restraint device for mounting a child in an automobile and placing the child on the seat of the automobile to secure the body of the child in a sitting state. It is about.

Generally, the seat of an automobile is designed according to the size of an adult body, and it is difficult for a child to sit stably. The seat belt is also attached on the assumption that it is worn by an adult, and if a child with a small body directly wears this seat belt, the correct wearing condition cannot be obtained, which is rather dangerous in the event of an accident.

Under such circumstances, it has been practiced to make a child sit on a special child restraint device and to attach the child restraint device to the seat of the vehicle in a detachable manner. It can be done.

Thus, the child restraint device can be attached / detached to / from an automobile seat by a simple operation, and when it is attached to the automobile seat, it is securely secured on the automobile seat and is attached to the automobile seat. It is necessary that the body of the child can be restrained surely, and it is desirable that it can be used for a long period of time according to the growth of the child.

2. Description of the Related Art Conventionally, as a child restraint device of this type, the actual device is 59-54325
The publications described in Japanese Utility Model Publication No. 60-192942 are known. The child restraint devices described in these publications place a child seat body on a seat of an automobile, secure the restraint device in the seat of the automobile by a seat belt provided in the automobile, and The child seat belt device that is fastened to the child restrains the body of the child.

Problems to be Solved by the Invention By the way, these child restraint devices are usually designed for infants 0 to 4 years old. These infants are so small that they cannot sit stably in the car seat,
Since it may move around in the automobile and interfere with the driving operation, it is preferable to firmly restrain the body with the restraint device as described above.

However, these child restraints are cramped and unusable as the child grows older than 5 years. Although it is possible to extend the usable period to some extent by enlarging the seat body, it is not preferable because the stability of the body in infancy is insufficient.

However, children aged 5 to 10 cannot use the restraint device as described above, but their body is still too small to directly sit on the seat of the car. When a small child sits down in the seat, it is often difficult to see the outside through the window, and when the seat belt is fastened, the shoulder belt comes into contact with the child's neck and the shoulder in the event of an accident. The belt may cause injury to the neck and is extremely dangerous.

Therefore, in recent years, booster seats have been put on the market to be placed on a seat so that a child can sit on the seat. This booster seat raises the position of the buttocks when the child sits on it, which raises the upper body of the child to an appropriate position so that the child can see outside the window and the seat The belt also allows proper tightening and is usually designed for children aged 5 to 12 years.

Even when the child restraint system described above is used, it is uneconomical to purchase and use the booster seat again if the child grows up to be about 5 years old or older.

The present invention has been made in view of the above circumstances, and can be used as a restraint device for infants while the child is an infant under 4 years old, and when the child grows up to 5 years old, An object of the present invention is to provide a child restraint device that can be used as a booster seat for children by removing the parts.

In this specification, the word "infant" is tentatively 0 to 4
The term "children" refers to children aged 5-12 years, but this division of age is not strict, and there are children who can be seated in restraint systems according to their growth. If the child is an "infant" who has grown cramped in the restraint system and is no longer using the booster seat, he / she will be treated as an adult.

Means for Solving Problems The child restraint system of the present invention incorporates a pedestal on which a child can sit in a state in which the child is seated on the seat of an automobile and an infant seat belt device for restraining an infant. The seat main body and a frame slidably joined to the seat main body in an arc shape are detachably coupled to the upper portion of the pedestal.

In the present invention, in a state in which the pedestal and the frame are combined, the pedestal and the frame are secured to the seat by the seat belt attached to the vehicle, and the infant is seated on the infant seat main body connected to the frame. By restraining the infant with the infant seat belt device,
It is possible to safely carry infants.

When the child grows up to become a child, the frame is removed from the pedestal, the pedestal is placed on the seat to seat the child, and the child is allowed to wear the seat belt attached to the automobile.

Embodiments The drawings show one embodiment of a child restraint device to which the present invention is applied. This child restraint device comprises a pedestal 1 and an infant restraint device 2 which is detachably fixed on the pedestal 1. The infant restraint device 2 includes a frame 3
And a seat body 5 mounted on the frame 3 via a slide device 4. The frame 3 is formed by bending a metal pipe, and the front end and the rear end of the fixed portion 6 fixed to the pedestal 1 are bent upward to form support portions 7 and 8, and both side portions thereof are formed. An arc-shaped guide rail 9 is installed between the supporting portions 7 and 8.

Further, the seat body 5 is formed by plastic blow molding, and the backrest portion 10 and the seat portion 11 are integrally formed into a substantially “L” shape.
It is formed in a letter shape, and the side restraint portions 12 are integrally formed on both sides thereof. Cushions 13 are attached to the backrest portion 10 and the seat portion 11, and seatbelt insertion holes 14 are provided in upper and lower two stages at portions corresponding to both shoulders of the child.

Sliders 15 that slide along the guide rails 9 attached to the frame 3 are attached to both sides of the lower portion of the seat portion 11. The sliders 15 and the guide rails 9 constitute the slide device 4. As the slider 15 slides along the guide rail 9, the seat body 5 is displaced in an arc with respect to the frame 3 and reclines.

In addition, the seat body 5 has an infant seat belt device according to the present invention.
16 is installed. Reference numeral 17 denotes a buckle, one end of which is a support body fixed to the center of the front end portion of the seat portion 11 of the seat body 5.
Is attached to the other end of. Two tongues 19 are connected to the buckle 17, and a webbing is inserted through each tongue 19 to form a shoulder belt portion 20 and a waist belt portion 21.

The pedestal 1 is also formed by plastic blow molding, and a center portion thereof forms a seating surface 23 on which a child can sit, and both side portions of the seating surface 23 are formed substantially in the side view. A "concave" shaped restraint 24 is formed. The fixing portions 6 of the frame 3 are placed on both sides of the seat surface 23 and fixed by bolts 25.

Reference numeral 26 is a cloth cover for covering the surface of the pedestal 1, which is folded and stored in a storage chamber 27 on the bottom surface of the pedestal 1.

Thus, in order to attach the child restraint system to the automobile seat, as shown in FIG. 2, the pedestal 1 is placed on the seat portion 28 of the automobile seat with the frame 3 and the pedestal 1 coupled to each other. ,
The automobile seat belt 29 is inserted between the frame 3 and the slide device 4 to connect the buckle 30, and the recess 31 of the pedestal 1 is used to secure the seat belt 28 on the seat portion 28. In this case, if the vehicle seat belt uses an emergency lock retractor, pull out the webbing from the emergency lock retractor over its entire length, and remove the looseness of the webbing midway along the way. It is preferable that the webbing is attached in a state where the webbing is not loosened.

Next, when an infant is allowed to sit on this child restraint device, the infant 32 is placed on the seat portion of the seat body 5 as shown in FIG.
With the backrest part 10 seated on the backrest part 10, the support 18 is positioned through the crotch of the baby 32 to position the buckle 17 on the abdomen, and the shoulder belt part 20 and the waist belt part 21 are held on the shoulder part of the baby 32 and Hang it around your waist and connect the left and right tongues 19 to the buckles 17, respectively. As a result, the infant 32 is restrained by the seat body 5 by the five-point seat belt.

Next, when reclining this child restraint device, by sliding the slider 15 forward along the guide rail 9, the angle of the seat body 5 with respect to the frame 3 changes, and the seat body 5 falls backward. , Is in a reclining state as shown by a chain line in FIG.

In the drawings, the child restraint device is placed forward on the car seat so that the child can be seated in the direction of travel of the vehicle. It can also be placed backwards on top, allowing the child to sit face-to-face with another ride.

Next, when the child grows up to become a child, the bolts 25 are removed, the connection between the frame 3 and the pedestal 1 is released, and the pedestal 1 is covered with the cloth cover 26, and the pedestal 1 becomes a booster seat as it is. That is, as shown in FIG. 3, the pedestal 1 is placed on the seat portion 28 of the automobile seat, and the child 33 is seated thereon. By wearing the car seat belt 29 in this state,
Even small children can be properly worn.
