Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a locking clip used for adjusting the length of an automobile seat belt.

[0002]

[Prior Art]

 As shown in an example in FIG. 8, this type of locking clip is composed of a frame portion a having a substantially "Sun" shape, a lock portion b is provided at the center of the frame portion a, and the lock portion b is sandwiched between the pair of locking clips. Slits c are provided. This locking clip is attached to a neck portion f of a loop e formed by folding back the belt d in the middle thereof. The belt d vertically overlaps at the neck portion f, enters the one slit c in the overlapped state, is folded back on the lock portion b, and exits from the other slit c.

[0003]

[Problems to be solved by the device]

 By the way, in the case of the above-mentioned conventional example, when the locking clip is attached to the neck portion f and the belt d including the loop e is tightened, the neck portion f is always locked. The slack must be created by applying a large force to d, which is not easy to adjust. Therefore, the present invention solves such a problem.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, a belt locking clip according to the present invention comprises a first slit, a first slit, a second slit, and a third slit, which are arranged in this order at intervals in the length direction of a belt. The first and second belt portions forming the neck portion pass through in an overlapping manner, and the first and second belt portions passing through the first slit are folded back, and then the first belt portion passes through the second slit, The two belt portions are characterized by passing through the third slits separately.

[0005]

[Effect] Either one of the first and second belt parts, for example, the first belt part is fixed, and the buckle which is supported in advance on the immovable side in a state where the loop is free to move in its length direction. When engaged with the connecting member, if there is slack on the loop side, in the first slit, both the first and second belt parts cannot be pressed against the corner of the locking clip facing the first slit, so there is no movement. Further, in the second slit and the third slit, the first and second belt portions separately pass therethrough, so that each belt portion is also free to move. Therefore, when the second belt portion is pulled in the direction in which the slack of the loop is eliminated, the first belt portion is brought into the tightened state, and the corner portions of the locking clip where the first and second belt portions face each other at the first slit. The first belt portion including the loop is kept in the tightened state by being locked to press the first belt portion.

The locking clip 10 is positioned so that the overlapping shoulder portion 4 and lap portion 7 in the neck portion 9 do not move relative to each other when locked, and the length of the loop 8 can be adjusted when the locking clip 10 is unlocked.

In FIGS. 1 and 3, the locking clip 10 is formed with three first to third slits 11 to 13 extending in parallel to a direction orthogonal to the length direction of the belt. A communication groove 14 is formed in the longitudinal direction of the belt between the central portions of the slits 11 to 13.

First to fourth lock portions 15 to 18 are provided between both ends of the locking clip 10 in the belt length direction and between the slits 11 to 13.

As is apparent from FIG. 1, the first slit 11 includes the shoulder portion 4 and the lap portion 7 of the neck portion 9 which are overlapped with each other, and the first slit portion 11 and the lap portion 7 are joined together to extend from the bottom of the first lock portion 15 to the top of the second lock portion 16. It is the part that passes toward.

The second slit 12 is a portion of the neck portion 9 folded back on the second lock portion 16 in which only the lower lap portion 7 obliquely passes downward of the third lock portion 17. The wrap portion 7 extending from the second slit 12 extends below the locking clip 10 toward the buckle 6.

In the third slit 13, of the neck portion 9 folded back on the second lock portion 16, only the shoulder portion 4 which is the upper side passes over the third lock portion 17 and goes to the lower side of the fourth lock portion 18. The shoulder portion 4 that is a portion that obliquely passes toward the outside extends from the third slit 12 toward the buckle 6 through between the fourth lock portion 18 and the lap portion 7.

As is apparent from FIG. 4, the lower portion of the first lock portion 15 facing the first slit 11 forms a first corner portion 20 against which the shoulder portion 4 is pressed, and the upper portion of the opposing second lock portion 16. Forms a second corner portion 21 against which the wrap portion 7 is pressed.

As is apparent from FIG. 5, the upper portion of the second lock portion 16 and the lower portion of the third lock portion 17 which face the second slit 12 respectively have a third corner portion 22 and a fourth corner portion 22 against which the lap portion 7 is pressed. The corner portion 23 is formed.

As is apparent from FIG. 6, the upper portion of the third lock portion 17 and the lower portion of the fourth lock portion 18 which face the third slit 13 have fifth corner portions 24 and sixth portions on which the shoulder portions 4 are pressed, respectively. The corner portion 25 is formed.

As is apparent from FIG. 7, the lower portion of the fourth lock portion 18 on the side not facing the third slit 13 forms a seventh corner portion 26 to which the shoulder portion 4 continuing to the loop 8 is pressed, and this portion Is a stabilizer that stabilizes the locked state of the neck 9.

Next, the operation of this embodiment will be described. First, in FIG. 2, the child seat 2 is placed on the vehicle seat 1, and the loop 8 of the seat belt 3 is temporarily adjusted to be long and the male and female members of the bag 6 are connected. In this state, the slack remains in the loop 8 and the child seat 2 cannot be fixed.

Further, as apparent from FIG. 1 and FIG. 4, since the shoulder portion 4 and the lap portion 7 are both loose, they are not pressed against the first corner portion 20 and the second corner portion 21, respectively. Instead, the shoulder portion 4 is free to move in the direction in which the lap portion 7 is tightened (direction indicated by arrow F).

Moreover, as is apparent from FIG. 1 and FIGS. 5 to 7, the shoulder portion 4 is connected to the fifth corner portion 24, the sixth corner portion 25 and the seventh corner portion 26, and the lap portion 7 is formed. It is not pressed against the third corner portion 22 and the fourth corner portion 23, and is freely movable in each length direction.

Therefore, when the shoulder portion 4 is pulled in the direction indicated by the arrow F, the slack in the loop 8 is removed, and when the lap portion 7 is tightened between the buckle 6 and the floor anchor 7a, the shoulder portion 4 becomes lapped. 7 is pressed against the first corner portion 20 and at the same time the lap portion 7 is pressed against the second corner portion 21 by the shoulder portion 4, so that the neck portion 9 is locked and the shoulder portion 4 and the lap portion 7 cannot move relative to each other. Positioned.

At the same time, in the second slit 12, as is apparent from FIG. 5, the lap portion 7 is pressed against the third corner portion 22 by the shoulder portion 4 and is pulled toward the fourth corner portion 23 by its own pulling. Since it is pressed, it becomes locked.

Further, in the third slit 13, the shoulder portion 4 is pressed against the fifth corner portion 24 and the sixth corner portion 25 to be in the locked state, as is apparent from FIG.

Further, as apparent from FIG. 7, since the shoulder portion 4 is pressed against the seventh corner portion 26, the locking clip 10 is pushed up to balance with other force, and the locked state of the neck portion 9 is maintained. I'm stabilizing.

When the buckle 6 is connected, it is only possible to pull the shoulder portion 4 in the direction indicated by the arrow F to tighten the loop 8 and the wrap portion 7, as is apparent from FIG. That is, the movement in the direction opposite to the arrow F, that is, the movement in the direction in which the loop 8 is loosened, is such that the lap portion 7 remains in the tightened state and the shoulder portion 4 is pressed against the first corner portion 20 and remains in the locked state. Therefore, it is impossible.

Therefore, in FIG. 2, even after the loop 8 is connected to the vehicle seat 1 via the buckle 6, the shoulder portion 4 can be pulled to adjust the length of the loop 8, so that the loop 8 of the seat belt 3 can be adjusted. The child seat 2 can be fast and surely fixed onto the vehicle seat 1 by the wrap portion 7 including the portion. Moreover, it is possible to prevent loosening during use.
