Description

[Detailed Description of the Invention] The present invention relates to a mechanism for indicating that a load has been applied to the seat belt of an automobile to the extent that it must be replaced.

Generally, drivers are encouraged to wear seat belts when driving. If you are involved in an accident and a load above a certain level is applied to the seatbelt, it is desirable to replace the seatbelt.

However, for general users, it is difficult to determine whether the load has been applied to the point that it requires replacement.
Even when a load is applied to the belt to the extent that it does not require replacement, the belt may have to be replaced, which is uneconomical.

In view of the above-mentioned problems, the present inventor devised this invention in order to improve the problem.The purpose of this invention is to ensure that the user is aware that a load above a certain level has been applied to the seatbelt. To provide a seatbelt replacement instruction display mechanism that allows a user to notify the user of the seatbelt's function and check the function of the seatbelt more easily than before.

In order to achieve this purpose, the present invention fixes a fixing member such as a bolt to which a display is attached to the vehicle body, and attaches a seat belt to one end of the fixing member through a holding member that deforms when a load is applied to the fixing member. The gist of the invention is to insert a support member connected to the support member, and to form a display window through which the display unit faces when the support member is moved to the surface of the cover integral with the support member that faces the display unit. It is said that

A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a diagram showing an example in which the seat belt replacement instruction display mechanism according to the present invention is applied to a three-point seat belt. 3 is folded back via a through ring 5 fixed to the center portion 4 of the center pillar 1, and the folded seat belt 2 is attached to the floor body 8 between the front seat back 6 and the hand brake lever 7. A buckle 10 which can be engaged and detached via an engagement member 9 is folded back through a through ring 11, and the tip of the folded back seat belt 2 is fixed to an inner side 12 of a side sill of a vehicle body.

By passing the buckle 10 in front of the driver 13 and engaging it with the engaging member 9, the seat belt 2 is supported at three points: the center portion 4 of the center pillar, the floor body 8, and the inner side portion 12 of the side sill. , restricts the driver from running forward.

In this embodiment, a seatbelt replacement instruction display mechanism is adopted for each of the above three points, and its specific configuration will be explained based on FIGS. 2 to 7.

That is, Fig. 2 is a front view of the display mechanism adopted in the central portion 4 of the center pillar, and Fig. 3 is a vertical side view thereof. It is represented by an imaginary line.

An anchor bolt 14, which is a fixing member, is fixed to the center portion 4 of the center pillar through a collar 15 and a nut 16, and a cap 19 provided with a display portion 18 is placed over the head portion 17 of the anchor bolt 14.

A through-anchor plate 20, which is a support member, is attached to one end of the anchor bolt 14 to which the seat belt 2 is connected via a through-ring 5. That is, the through anchor plate 20 is formed with a long hole 21 whose long diameter is in the load direction, and between the long hole 21 and the anchor bolt 14, the loader 22, which is crushed by a load above a certain level, is placed in the moving direction, that is, the part where the load is applied. By interposing the through anchor bearing 23, which is a holding member embedded in the anchor bolt 14, the through anchor plate 20 is attached to the anchor bolt 14.
is inserted and supported.

Further, a cover 24 is integrally attached to the through anchor plate 20, and a display window 26 is formed on the front surface 25 of the cover 24, that is, the surface facing the display section 18, and as shown in FIG.
2 is not collapsed, the display window 26 is positioned above the display section 18.

In the above, when a load exceeding a certain level is applied in the direction of the arrow, the loader 22 in the bearing 23 is crushed and the through anchor plate 20 falls downward by this amount, as shown in FIGS. 4 and 5. Then, the cover 24 that is integrated with the through-anchor plate 20 also lowers, and the display window 26 formed on the front surface 25 of this cover opens onto the anchor bolt head 17.
It matches the height of the display section 18 provided in the display window 26.
The display section 18 can be visually recognized from this point on.

FIG. 6 shows another embodiment in which a display mechanism is adopted in the inner part 12 of the side sill. An anchor bolt 114 is fixed to the inner part 12 of the side sill through a collar 115 and a nut 116. The head portion 117 of the device is covered with a cap 119 having a display portion 118 provided thereon. An elongated hole 121 in the load direction is formed in the anchor bolt 114, and a through anchor plate 120 is attached to the upper end by folding back the tip of the seat belt 2.
is inserted between the elongated hole 121 and the anchor bolt 114 via a through anchor bearing 123 with a loader 122 embedded in the lower part, and the front surface 125 of the cover 124 integrated with the plate 120 is inserted.
A display window 126 is formed therein.

In this embodiment, similarly to the above, when a load of a certain level or more is applied, the loader 122 collapses, and the cover 124 is moved upward by an unillustrated spring or the like, and the display part 11 is removed from the display window 126.
8 is visible.

FIG. 7 shows another embodiment adopted for the support part of the floor body 8, in which an anchor bolt 214 is fixed to a bracket 200 installed upright on the floor body, and a display part 218 is formed on the head part of this anchor bolt 214. A through anchor plate 22 that covers the cap 219 and extends from the engagement member 9 is located in the middle of the anchor bolt 214.
0 is inserted through a long hole 221 and a through anchor bearing 223 provided with a loader 222 at the bottom, and a cover 224 with a display window 226 formed on the front surface 225 covers the head portion 217 of the anchor bolt. When a certain load is applied, the loader 222 collapses, and the plate 220 can be lifted upward by the loader 222. When the plate 220 is pulled up, the cover 224 also moves upward,
The display section 218 is made visible through the display window 226.

By doing the above, it can be easily determined that a load of a certain level or more is applied to the seat belt.

Note that the above-mentioned example is merely an example of the implementation of the present invention, and the present invention is not limited thereto. For example, the hole formed in the through-anchor plate is not limited to a long hole, but may be a circular hole, and the fixing member is not limited to an anchor bolt, and an indicator may be colored directly on the bolt head.

As is clear from the above explanation, according to the present invention, a fixing member such as a bolt provided with a display part is fixed to the vehicle body, and the seat belt is attached via a bearing that is deformed by the load by burying the loader. Since the plates connected to each other are inserted into the fixed member, for example, the support member can be connected to the fixed member with adhesive, and the tension applied to the seat belt can be used to release this connection and move the support member. Compare,
The set load capacity does not change due to long-term use or temperature changes, and compared to a system in which the support member is engaged with the fixed member in a press-contact state, and the engagement position is shifted by the tensile force acting on the seat belt. Therefore, there is no distortion caused by vehicle running vibrations or daily use of the belt, and it is possible to set the load capacity more reliably, and the load suitable for the location of use can be freely selected simply by selecting the loader.

In addition, since the cover integrated with the plate is formed with a display window through which the display section faces when the plate moves, it is possible to reliably display that a load above a certain level has been applied to the seat belt.
In addition, since the user can easily visually confirm the display, it becomes possible to properly instruct the user to replace the seat belt. Furthermore, the display mechanism itself is simple and has many advantages, such as no failures.
