[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a buckle mainly applied to an automobile seat belt.

[0002]

2. Description of the Related Art As shown in FIG.
(2) is pulled out from the retractor (3) attached to the body (1), passed through the support ring (4) and fixed at the end to the body (1), and the tongue (5) can slide in the middle part Mounted on The tongue (5) is fixed to a buckle (6) protruding from the side of the seat (7). In this state, the tongue (5) and the retractor (3) turn to the shoulder belt (2A).
And the waist belt (2B) from the tongue (5) to the end.

In order to attach a child seat (8) to a seat (7) equipped with such a seat belt (2), conventionally, as shown in FIG.
(8A) Buckle tongue (5) through seat belt (2)
(6), and fasten the seat belt (2) to the retractor (3).
Child seat by waist belt part (2B) pulled to the side
(8) was tightened and fixed with a locking clip (9).

[0004]

However, in the above-mentioned conventional structure, a separate member such as a locking clip (9) is required for attaching the child seat (8) to the seat (7).

[0005]

According to the present invention, as a means for solving the above-mentioned conventional problems, a buckle into which a tongue (5) for dividing a waist belt portion (2B) and a shoulder belt portion (2A) is inserted. In (6), the tang (6) of the buckle (6)
A), a ratchet mechanism (10) is attached so as to be able to be inverted, and the ratchet mechanism (10) has a frame (1) having a tongue through-hole (12) inside.
1) and a claw portion (13) formed at the upper edge of the frame (11) and penetrating into the seat belt (2) to prevent the seat belt (2) from sliding toward the waist belt. ) Buckle (6).

[0006]

[Function] If the ratchet mechanism (10) is tilted, the tongue (5) is moved from the tongue insertion port (6A) to the buckle (6) through the tongue through hole (12) of the frame (11) of the ratchet mechanism (10). Insert the tongue (5) into the buckle (6). When the tongue (5) is fastened to the buckle (6) with the ratchet mechanism (10) upright, the claw (13) of the ratchet mechanism (10)
Bites into the seat belt (2), and the seat belt (2) is prevented from sliding toward the waist belt (2B).

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to an embodiment shown in FIGS. 1 to 3. A buckle (6) for fastening a tongue (5) of a seat belt (2) is provided with a seat (7) as shown in FIG. The buckle (6) has a ratchet mechanism (10) attached to the tongue insertion port (6A) of the buckle (6). The ratchet mechanism (10) has a buckle (6) at the root end.
U-shaped frame (11) pivotally attached to the periphery of the tongue insertion opening (6A), a tongue through hole (12) formed inside the frame (11), and the frame ( 11) Claws formed on the upper edge
(13), and is made of an elastic material such as plastic.

In the above construction, the tongue (5) of the seat belt (2) is inserted into the tongue through hole of the ratchet mechanism (10) when the ratchet mechanism (10) is folded down as shown by the dotted lines in FIGS. (12) fastened crowded difference buckle tongue insertion port (6) (6A) from back cycle (6) through. In this state, the seat belt (2) is normally used, and the shoulder belt portion (2A) from the tongue (5) to the retractor (3) and the waist belt portion (2B) from the end.

When the ratchet mechanism (10) is set up as shown by the solid line in FIGS. 2 and 3, the ratchet mechanism (10) is
Claw (13) elastically bites into the seat belt (2),
The seat belt (2) is prevented from sliding toward the shoulder belt (2A). Therefore, as shown in FIG. 5, the child seat (8) is placed on the seat (7), and the ratchet mechanism (10) of the buckle (6) is passed through the seat belt (2) through the side hole (8A) of the child seat (8). With the buckle (6) in the upright position, fasten the tongue (5) of the seat belt (2) to the seat belt (2).
Is pulled toward the shoulder belt side, and the child seat (8) is fastened by the waist belt portion (2B). The tightening of the waist belt portion (2B) is prevented from being loosened by a ratchet mechanism (10) of a buckle (6).

[0010]

According to the present invention, the seat belt can be prevented from sliding from the tongue fastened to the buckle to the waist belt side without having to replace the buckle of the seat belt or use a locking clip. It is convenient to fasten and fix an article such as a child seat placed on the seat by the waist belt portion.
