The base 100 is mounted longitudinally on the side of the seat back S, as shown in [FIG. 3]. At this time, the base 100 guides the slider 200, which will be described later, so that the height can be adjusted while moving along the longitudinal direction of the base 100. In particular, the base 100, which is long installed on the seat back (S), moves together with the seat back (S) even if the seat back (S) is tilted forward or backward depending on the preference of the driver or passenger. ) is in any position, the seat belt (B) that passes through the slider (200), which will be described later, mounted on this base (100) supports the upper body of the seat belt wearer diagonally across. Accordingly, the seat belt (B) can stably support the seat belt wearer when an accident occurs.

On this base 100, several teeth 110 are formed to protrude in two rows, as shown in [FIGS. 4] to [FIG. 7].

tooth

As shown in [FIGS. 4] to [FIG. 7], several teeth 110 are formed to protrude in two rows on one side of the base 100 described above, that is, the side that does not contact the seat back. At this time, the teeth 110 cause the button member 300 to be disengaged from the teeth 120 when the button member 300, which will be described later, moves toward the center of the length of the base 100, and on the contrary, the button member ( As 300 moves outward from the center of the base 100 by receiving elastic support, the button member 300 is formed to engage with the teeth 110.

On the base 100 constructed in this way, a slider 200 is mounted so that it can move along the longitudinal direction of the base 100, as shown in [FIGS. 4] to [FIG. 7].

me. slider

The slider 200 is formed to surround the base 100 described above, as shown in [FIGS. 4] to [FIG. 7]. This is to enable the height of the seat belt B to be adjusted by moving the slider 200 along the longitudinal direction of the base 100 fixed to the seat back. At this time, the slider 200 is mounted so that it can slide by having both ends bent in the form of angle brackets and the above-described base 110 inserted therein.

In this slider 200, as shown in [FIG. 4] to [FIG. 7], a space is provided between the base 100 to mount a button member 300 to be described later, and the base 100 is on one side. An installation hole 210 is formed through the seat belt (B) so that it can be inserted and slid in parallel.

At this time, it is preferable to assemble the seat belt (B) while inserting it through the installation hole 210 in advance when assembling it, but more preferably, a slit is formed in the installation hole 210 so that the seat belt (B) is already installed. It is desirable to configure the seat belt (B) so that it can be used by inserting it into the installation hole 210 in the width direction.

In this slider 200, as shown in [FIG. 4] to [FIG. 7], a button member 300, which will be described later, is mounted on the surface facing the base 100 to operate while receiving elastic support, and the above-described tooth 110 ) is engaged.

all. absence of buttons

Two button members 300 are installed on the slider 200, as shown in [FIGS. 4] to [FIG. 7]. At this time, the button member 300 is elastically supported by the spring 310 and is mounted so that it can move in opposite directions along the width direction of the slider 200.

That is, the button member 300 is elastically supported by a spring 310 on one side of which is supported by the slider 200, as shown in [FIGS. 4] to [FIG. 7], and moves along the width direction of the slider 200. It is installed to receive force in the direction it protrudes outward. And a jaw 320 is formed at the end of the slider 200, so that the slider 200 is supported by the spring 310 and engages with the teeth 110 described above.

Accordingly, the button member 300 receives elastic support from the spring 310 so that the jaw 320 is always engaged with the teeth 110 to maintain the slider 200 fixed to the base 200, and the slider ( 200) When the button member 300 protruding outward is pressed, the engagement of the jaw 320 engaged with the teeth 110 is released, allowing the slider 200 to move along the base 100 to adjust the height. . Of course, if the force applied to the button member 300 is removed again in a state in which the height is adjusted in this way, the jaw 320 engages with the adjacent teeth 110 and the support height maintains the adjusted position.

Meanwhile, in a preferred embodiment of the present invention, the two button members 300 are shown in [FIGS. 4] to [FIG. 7] as an example in which the two button members 300 are formed to engage teeth 110 at offset positions, but the wire As the button members 300 are manufactured using a thin material such that they do not overlap each other, anyone in the technical field to which the present invention pertains can understand that they can be configured to engage the teeth 110 at opposing positions. It will be easy to find out.

As described above, the present invention is configured so that the height of the slider moving along the longitudinal direction of the base mounted on the seat back can be adjusted, making it possible to easily and conveniently adjust the support position of the seat belt fitted to the slider. At this time, since the base moves together with the seat back, the seat belt stably restrains the upper body of the seat belt wearer regardless of the position of the seat back, thereby reducing the degree of injury. In addition, since the operation of the slider is restricted or released by two button members that operate opposite to each other, it is possible to prevent the slider from malfunctioning even if either button member is accidentally pressed.
