Description

[Detailed Description of the Invention] The present invention relates to a belt adjustment fitting, specifically an adjustment fitting for a safety belt for a vehicle, and in particular, an anti-shock fitting that can completely prevent deformation or damage even when subjected to impacts in any direction. Regarding belt adjustment fittings.

Conventionally, in the tongue plate of a safety belt or the like, adjustment fittings consisting of a tongue plate having a belt insertion opening for adjusting the length of the belt, side walls rising from both side edges of the plate, an adjustment bar spanning between the side walls at the opening, and a cover member for covering the adjustment bar are widely used and well known.

However, since this adjustment metal fitting is present in the range of movement when the door of the vehicle is opened and closed or the seat is moved, the adjustment metal fitting may be caught between the vehicle body and the seat and receive a shock.

At this time, if the impact direction is perpendicular to the both side walls or if the entire surface of the cover receives a uniform impact, deformation or damage to the cover due to the action of the rising side walls can be relatively avoided.
Depending on the state in which the impact direction is sandwiched, a concentrated load may be applied from above parallel to both side walls and at the center between both side walls, for example from above in the XX direction, which is the vertical direction of the board 5 in FIG. When the cover receives an impact or a shock, there is no rising part on the inside of the cover corresponding to the above-mentioned side walls in this direction, and there is an empty space.Furthermore, since covers these days are often made of synthetic resin, they deform with a slight force. There is a defect that may cause damage or damage.

In view of the above, the present invention aims to eliminate the above-mentioned conventional defects and provide an adjustment fitting that does not deform or damage the cover member even if an impact is applied to the cover member in any direction. A belt adjustment fitting with a cover comprising: a base plate having a bottom portion thereof; both side walls rising from both side edges of the base plate; and an adjustment bar extending between the both side walls in the opening and around which the belt is passed. The device is characterized in that a rising wall having substantially the same height as the side wall is provided between the end portions of both side walls in a direction perpendicular to the wall.

Hereinafter, details of the present invention will be described based on embodiments shown in the accompanying drawings.

FIG. 1 shows how the adjustment fitting of the present invention is assembled, and FIG. 2 shows a longitudinal sectional view of the adjustment fitting after assembly.

In these figures, 1 is a plate-shaped substrate having a belt insertion opening 2 in the bottom plate such as a tongue plate, and a latch hole 5 at the tip; 4 is an adjustment bar that extends between the side walls 3 and 3 in the opening 2 and wraps around the belt 9; 6 is a spring that biases the adjustment bar 4; The main part of the metal fitting is covered with a cover member 8 as shown in FIG. Cover member 8
is usually made of synthetic resin, etc., and has a box-shaped lid 8.
a and a bottom plate 8b, and both can be opened and closed by a hinge part 8c between them, and can be locked by a locking part 8h provided on the bottom plate 8b. The board 1 is inserted into the insertion opening 8e.
By inserting the tip end thereof, it is assembled with the adjustment fitting as shown in FIG.

Therefore, the present invention is characterized in that a spacer 7a is provided between the ends of the side walls 3, 3 of the substrate 1 in the above structure.

That is, in FIG. 1, this spacer 7a is shown as a plate-shaped member with both ends bent inward.
Notches 7-1, 7-1 are provided at both ends so as to be inserted into the rear end portions 3a, 3a of the side walls 3, 3, and the locking members 8f, 8f of the cover member 8 when stored in the cover member 8. Notches 7-2, 7-2 of the spacer 7a are provided at corresponding positions so that the spacer 7a is fixed by the locking recesses 8g, 8g of the spacer 8f, and the spacer 7a is attached to the cover member 8 as shown in FIG.
It is stored and fixed inside.

3 and 4 show other embodiments of the present invention, in which the spacer 7a in FIGS. 1 and 2 is shown.
The corresponding parts are cut and raised parts 7b and 7c that are integrally raised from the substrate 5 by press working, etc., and are located at both front and rear ends 3a, 3a, 3 of both side walls 3, 3.
It is the same as the example in FIGS. 1 and 2, except that it is provided in the right angle direction between b and 3b to serve as a spacer member. Therefore, descriptions of other parts will be omitted.

As mentioned above, the most distinctive feature of the present invention is that it includes a separate body that can be inserted between the rear ends 3a, 3a of both side walls 3, 3 in a direction perpendicular to the side walls 3, 3a, as shown in FIGS. 1 and 2. The spacer 7a, as shown in FIG. 3 and FIG.
A, 3a, 3b, 3b are provided with cut-and-raised portions 7b, 7c that stand up integrally with the substrate 5, and in short, the end portions of both side walls 3, 3 are perpendicular to the side walls 3, 3. It is sufficient that a rising wall is provided between them at approximately the same height as the side wall, and such a rising wall may be a separate body as described above, or may be integrated with the substrate 5. It may be both between the front and rear ends of the walls 3, 3, or either one, and both side walls 3,
The position may be near the front and rear ends of the space between 3 and 3, and various other design changes are possible, all of which will achieve the intended purpose.

Thus, according to the present invention, in the known belt adjustment fitting, in addition to the both side walls raised from both side edges of the base plate, at least one raised side wall is provided between the ends of the both side walls in a direction perpendicular to the both side walls. Since the wall is provided, the cover member that covers the belt adjustment fitting is temporarily placed from above in a direction parallel to the both side walls, and between the both side walls, for example, above in the X-X direction, which is the vertical direction of the board in FIG. Even when a load or impact is applied intensively from the cover member, the upright wall serves as a strength member and can reliably prevent deformation or damage of the cover member. In addition, since the rising wall is housed in the cover member together with the both side walls, it is possible to avoid partial concentrated loads from above the upper surface of the cover member from any direction other than the X-X direction, The strength is further strengthened against loads applied to the entire upper surface, and the defect of the conventional structure, which was weak against loads and impacts in a certain direction, is completely eliminated.

As described above, the present invention has a configuration in which the rising walls are provided as described above, so that even if the cover member is made of synthetic resin, it is safe against loads and impacts in all directions due to the action of the well-known side walls. Therefore, even if the extra length belt adjustment fitting were to be caught between the vehicle body or the seat, the cover member would not be deformed or damaged, and the adjustment fitting would not function at all. It is an extremely useful device that is virtually intact.
