DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for adjusting an infant seat belt, and more particularly to an apparatus for adjusting an infant seat belt in which a buckle position of a seat belt can be freely adjusted.

[0002]

2. Description of the Related Art Infant seatbelt adjustment devices in which the position of an infant seatbelt can be freely adjusted include:
For example, there is one disclosed in JP-A-62-116337.

In such a conventional adjusting device, the lower end tongue of the shield connected to the shoulder belt is selectively fixed to one of a plurality of slots formed in the seat in the front-rear direction. The seat belt is adapted to the size of the infant.

[0004]

However, in the above-mentioned conventional baby seat belt adjustment device, the height of the shield can be adjusted even if the position of the shield including the buckle can be moved to the front of the seat. Therefore, there is a possibility that a gap may be formed between the shield and the crotch of the body or the body may become cramped due to individual differences and age differences in the body shape of the infant.

The present invention has been made to eliminate the above disadvantages.

[0006]

According to the present invention, there is provided an apparatus for adjusting a baby's seat belt, wherein a lower end mounting means of a front restraint belt connected to a buckle is provided in the seat so as to be movable in the front-rear direction of the seat. The length of the front restraint belt is increased when the means is at the front position of the seat, and the length of the front restraint belt is reduced when the means is at the rear position of the seat.

The lower end mounting means includes a base fixed in the seat, a movable base provided on the base and movable in the front-rear direction, a belt guide fixed to a front end of the movable base, Fixing means for selectively fixing the movable platform to the base at an arbitrary position in the front-rear direction of the seat, wherein a lower end of the front restraint belt is connected to a front end of the base via a belt guide of the movable platform. It is characterized by being fixed to.

The fixing means includes a plurality of pin holes formed in the base so as to be separated from each other in the front-rear direction of the seat, a pin inserted into an arbitrary one of the pin holes, A pin guide suspended from the rear end of the movable base to support the spring, a spring for always holding the pin downward so that the pin is inserted into the pin hole, and moving the pin upward against the spring It is characterized in that it comprises a pin lifting knob provided on the pin guide for the purpose.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, 1 is a seat, 2 is a backrest, 3 is a headrest, 4 is an armrest, 5 is a shoulder belt, 6 is a front restraint belt, and 7 is a belt for connecting these belts 5 and 6 detachably. , A shield for covering the front restraint belt 6 and the buckle 7, and 9 for the seat 1
In the present invention, a lower end fitting 11 of the front restraint belt 6 is provided on a frame 10 located inside the seat, and the front restraint belt 6 is extended upward through the seat 1 from the lower end mount 11, The upper end is connected to the buckle 7.

As shown in FIGS. 3 and 4, the lower end fitting 11 includes a base 12, two rails 13 extending parallel to each other in the front-rear direction of the seat 1 provided on the base 12, and A movable table 14 slidably supported by 13, a guide rod 15 fixed to a front end of the movable table 14 in a direction perpendicular to the rails 13, and a base 12 between the two rails 13. Three pin holes 16 formed apart from each other in the front-rear direction of the seat 1, a pin 17 inserted into any of the pin holes 16, and a rear portion of the movable table 14 supporting the pin 17. A pin guide 18 vertically provided at the end, a spring 19 for constantly lowering the pin 17 so that the pin 17 is inserted into the pin hole 16, and the pin 17 is moved upward against the spring 19. Above A lower end of the front restraint belt 6 extends through a gap between the moving table 14 and the guide rod 15 as shown in FIG. 5, and a front end of the base 12 is formed. To the part.

Since the infant seat belt adjusting device of the present invention has the above-described structure, when the infant is large in size, the knob 20 is searched from the upper surface of the seat 1 and the knob 20 is opposed to the spring 19. , The pin 17 is removed from the pin hole 16, and the carriage 14 is moved on the rail 13 to the front of the seat 1 using the guide as a guide. The pin 17 is inserted into the pin hole 16 at the front position to move the carriage 14 to this position. Can be fixed to the base 12.

In this state, as shown in FIG. 5, the buckle 7 is located at the forefront position of the seat 1, and the length of the front restraint belt 6 is increased, so that the height of the buckle 7 is also increased. Become like

The imaginary line in FIG. 5 shows the case of a small infant.

[0015]

As described above, according to the apparatus for adjusting a child's seat belt of the present invention, the length of the belt and the height of the buckle can be changed arbitrarily according to the child's body type so that the buckle can be used regardless of the baby's body type. Since the torso can be positioned in front of the center of the torso, there is a great advantage that the baby can be held safely and securely.
