Description

[Detailed Description of the Invention] <<Industrial Application Field>> This invention relates to an aid for restraining a child so that a seat belt attached to a vehicle seat can be used even by an infant.

<<Prior Art>> Normally, the seats of passenger cars are equipped with three-point seat belts, which must be worn while driving.

When worn, the seat belt restrains the occupant's chest and thighs to the seat in order to prevent bruises and other injuries caused by the occupant flying forward due to the impact of a collision.

《Problem that the invention aims to solve》 However, the pull-out angle of the seatbelt and its placement in relation to the seat are usually set for adults, and while for adults one side of the seatbelt passes through the chest, When worn by a small child, etc., it ends up passing near the neck. Therefore, conventional seat belts have become unsuitable for small-sized infants and children.
It cannot be used forcibly because it can cause a hanging phenomenon in the event of a rear-end collision, which can be even more dangerous.

In addition, a restraint chair specifically for infants called a child seat has been commercialized, but since the child seat is attached to the vehicle seat with a seat belt, it is troublesome to attach and detach the child seat.
It also requires a place for installation and storage,
This could not be said to be desirable from a practical point of view.

This invention was made based on the above-mentioned background, and its purpose is to provide an auxiliary device for restraining children, which allows existing seat belts to be adapted to infants.

<Means for Solving the Problems> In order to achieve the above object, this invention is an aid for child restraint used in a three-point seat belt that restrains the chest and thighs of the person sitting on the seat with webbing. The auxiliary device includes a breastplate member for infants, and a first locking portion and a second locking portion provided on the breastplate member, and the first locking portion is attached to the webbing. The second locking portion is removably locked to the thigh passage portion, and the second locking portion is removably locked to the chest passage portion of the webbing. It is characterized in that it has a length extending on a line that approximately connects the shoulder portion to the abdomen on the other side, so that the angle of inclination at the chest passage portion can be changed.

<<Operation>> According to the above structure, for example, after setting the three-point seat belt, the first locking part is locked to the thigh passage part of the webbing while the chest member is placed on the infant, and the webbing is After pulling the chest passage part somewhat, lock the second locking part to the chest passage part. As a result, the chest passage portion of the webbing is pulled toward the thigh passage portion side via the breast plate member, and as a result, the inclination angle thereof is changed to be adapted to the body shape of the infant.

<<Example>> Hereinafter, an example of this invention will be described in detail using the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a vehicle seat consisting of a seat cushion 2 and a seat back 3, and a three-point seat belt 4 is installed on the side of the seat 1.

The seatbelt 4 has the same configuration as the conventional one, and includes a webbing 6 that has one end locked in a retractor 5 so that it can be rolled up, a metal fitting 7 for attaching the other end of the webbing 6, and a chest passage portion 6a of the webbing 6. A connector 8 that separates or connects the thigh passage portion 6b, a relay anchor 9 provided above the retractor 5, a buckle 10 for attaching or detaching the webbing 6, and a tongue (unattached) that engages and disengages the buckle 10. (as shown).

And this seat belt 4 is in the first position in the normal state.
As shown by the imaginary line in the figure, the chest of an adult seated on the seat 1 is restrained to the same seat side with the chest passage part 6a hooked from the top of one front side of the seat bag 3 to the bottom of the other front side and tilted. However, sheet 1
If the person sitting on the seat is an infant as shown in the figure, the chest passage portion 6a of the webbing 6 will pass through the infant's neck.

However, this chest passage portion 6a is corrected by the infant restraining aid 11 of the present invention so that it passes through the infant's chest.

As shown in FIG. 2, the auxiliary device 11 includes a breast plate member 12 formed to match the shape of the infant's chest.
, a pair of shoulder bands 13 integrated with the back surface of the breastplate member 12 by sewing or the like, a first locking part 14 provided at approximately the middle of the lower end of the breastplate member 12, and A second locking portion 15 is provided on the front side of the member 12 and is inclined from an upper portion on one side to a lower portion on the other side.

The breastplate member 12 is formed, for example, by covering the surface of a cushion pad with a skin material made of vinyl chloride, cloth, or the like. Also, the first locking portion 14
It consists of a flexible strap 16 whose base end is fixed to the lower end of the breastplate member 12, and a button 17 provided at the base end has a slit 17 formed at the free end side of the strap 16. By passing through it, a loop is created.

On the other hand, the second locking portion 15 has a length that extends approximately on a line connecting the infant's shoulder on one side to the abdomen on the other side, and its upper edge in the longitudinal direction is attached to the chest plate member 12. It consists of a flexible bag that is sewn onto the bag and fixed by passing a button 18 provided at a corresponding position through a slit formed at the lower edge. Fixation using this button 18 is performed at multiple locations.

In order to have an infant sit in a restrained state on the seat 1 using the auxiliary device 11 configured as described above, the infant is first fitted with the shoulder band 13 so that the chest plate member 12 is positioned on the infant's chest, and then the infant is placed on the seat. Set the seat belt 4 with the passenger seated in the seat 1. Next, the first locking part 14 is hooked and locked to the main body passage part 6b of the webbing 6, and the chest passage part 6a is once pulled downward, and then the second locking part 15 is attached. If the chest passage part 6a is passed through the inside of the chest passage part 6a and the second locking part 15 is locked to the chest passage part 6a through the button 18, the chest passage part 6a will pass through the thigh as shown in FIG. It is attracted to the part 6b side,
The angle of inclination of the chest passage portion 6a is changed, and the infant is restrained in a state that is adapted to the infant's body shape.

Although the child restraint aid of the present invention does not require the above-mentioned shoulder band 13, by providing the band 13, the breast plate member 11 is integrally attached to the child, and the restraint by the webbing 6 is improved. The retention is done in a manner more adapted to the infant.

《Effects of the invention》 As explained in detail through each of the examples above,
The infant restraining aid of this invention has the following effects.

(b) The existing three-point seat belt can be applied to infants, avoiding dangers such as neck hanging in the event of a collision, and by providing cushioning properties to the chest plate, the chest plate also has a cushioning effect. safety can be further improved.

(b) The presence of the breastplate member increases the restraining force and avoids other dangers caused by the infant's movement.

(c) Compared to conventional child seats for vehicles, the breastplate member does not take up much space for storage and is easy to attach and detach.
