Description

  The present invention relates to a technical field of a seat belt guide anchor that is supported by a vehicle body such as a pillar and guides a seat belt of a seat belt device toward an occupant's shoulder and a seat belt device using the seat belt guide anchor.

  Conventionally, a seat belt device attached to a vehicle seat of an automobile or the like is configured to restrain an occupant with a seat belt in an emergency such as when a large deceleration acts on a vehicle such as a collision. As such a seat belt device, various seat belt devices including a seat belt guide anchor that is supported by, for example, a pillar of a vehicle body and slidably guides the seat belt have been proposed.

  This type of seat belt guide anchor is required to have good slidability between the seat belt and the seat belt guide anchor so that the seat belt can be wound and pulled out satisfactorily. Therefore, various seat belt guide anchors in which the seat belt sliding portion of the seat belt guide anchor is formed with low friction have been proposed.

  As such a conventional seat belt guide anchor, a seat belt guide in which a seat belt insertion hole forming portion of an insert metal fitting is coated with a coating resin and a slip piece made of a low friction material is provided on the seat belt sliding portion of the coating resin. An anchor has been proposed (see, for example, Patent Document 1). According to the seat belt guide anchor described in Patent Document 1, since the friction between the seat belt and the seat belt guide anchor is reduced by the slip piece, good slidability can be obtained. However, in the seat belt guide anchor described in Patent Document 1, it is necessary to use a slip piece that is a separate component from the insert-molded coating resin. For this reason, the number of parts increases, and the manufacturing cost increases accordingly.

  On the other hand, as another conventional seat belt guide anchor, in order to obtain low friction between the seat belt and the seat belt guide anchor as described above, dust adheres to the surface of the coating resin that covers the insert metal fitting. In order to suppress this, a seat belt guide anchor in which the surface of the coating resin is plated has been proposed (see, for example, Patent Document 2). According to the seat belt guide anchor described in Patent Document 2, since the adhesion of dust to the surface of the coating resin is suppressed by the plating process, the deterioration of the coating resin with time is suppressed, and good sliding properties are relatively improved. It can be maintained for a long time. Moreover, since the slip piece as described in Patent Document 1 is not used, the number of parts can be reduced.

JP 2000-135967 A. Japanese Patent No. 4248104.

  However, since the seat belt guide anchor described in Patent Document 2 uses plating, there is a problem that the number of manufacturing steps is large and the manufacturing cost is high. In addition, since it is necessary to perform post-treatment of the plating treatment, the number of manufacturing steps is further increased, and the production cost including the post-treatment costs is further increased.

  In addition, in the seat belt guide anchors described in Patent Documents 1 and 2, although the slidability of the covering resin itself of the insert metal fitting is considered, the slidability of the seat belt itself is not considered. . That is, there is a problem that the use of the seat belt device reduces the slidability of the seat belt itself because foreign matters such as dust adhere to the surface of the seat belt.

  The present invention has been made in view of such circumstances, and its purpose is to automatically remove foreign matters such as dust adhering to the seat belt to suppress a decrease in slidability of the seat belt itself, Moreover, the present invention is to provide a seat belt guide anchor and a seat belt device that can be manufactured at low cost.

In order to solve the above-described problems, a seat belt guide anchor of the present invention includes at least a metal plate and a coating resin that covers at least a seat belt sliding corresponding portion of the metal plate to form a belt insertion hole. In the seat belt guide anchor in which the seat belt is inserted through the belt insertion hole and guides the seat belt, the seat belt sliding portion of the coating resin is provided with a foreign matter removing portion that removes the foreign matter adhering to the seat belt. And a surface of the sliding portion of the seat belt is a first curved surface, a second curved surface that is different from the first curved surface and is recessed from the first curved surface, and the first curved surface. A step formed between the surface and the second curved surface, and the step extends along the belt insertion hole on the surface of the seat belt sliding portion of the coating resin. Are, the foreign matter removing portion is formed by the corner between the step and the first curved surface, wherein the angle section is characterized by being formed into a sharp edge.

  According to the seat belt guide anchor of the present invention configured as described above, the seat belt moves while sliding on the seat belt sliding portion of the coating resin when the seat belt is wound and pulled out. At this time, the surface of the sieve belt is rubbed by the foreign substance removing portion provided in the coating resin. Thereby, foreign matters such as dust adhering to the surface of the seat belt can be removed by the foreign matter removing section. Moreover, foreign matters such as dust adhering to the seat belt are automatically removed by the foreign matter removing portion when the seat belt is wound and pulled out, so that the seat belt itself can be removed without performing any special foreign matter removing work. It becomes possible to suppress a decrease in slidability.

In particular, the foreign substance removing portion is formed by a sharp edge that is a corner portion between the step extending along the belt insertion hole on the surface of the seat belt sliding portion of the coating resin and the surface of the seat belt sliding portion. Thus, the foreign matter removing effect of the seat belt by the foreign matter removing unit can be further increased.

Furthermore, the foreign matter removing portion is provided on the surface of the belt insertion hole opposing sliding portion of the seat belt sliding portion of the coating resin, so that the foreign matter removing portion The friction of the seat belt becomes stronger. Thereby, the foreign matter on the seat belt can be more effectively removed by the foreign matter removing portion at least one of when the seat belt is wound and withdrawn.

  Further, the foreign matter removal by the foreign matter removing unit can be automatically performed at all times when the seat belt is retracted by the seat belt retractor or when the seat belt is pulled out by the occupant. Accordingly, it is possible to suppress a decrease in the slidability of the seat belt itself due to the use of the seat belt device. As a result, the slidability between the seat belt and the seat belt guide anchor can be maintained better for a longer period of time, and the seat belt can be wound and pulled out smoothly.

  In particular, since foreign matter removal by the foreign matter removing unit is always automatically performed, the foreign matter attached to the seat belt has not passed so much time after attachment, and the adhesion force is often relatively small. Thereby, the foreign matter removal effect by the foreign matter removing unit can be more effectively exhibited.

Furthermore, in order to configure the foreign matter removing portion, only the step formed by the different curved surfaces is formed on the coating resin, so that the foreign matter removing portion is easily formed integrally with the coating resin when molding the resin. be able to. Therefore, the manufacturing cost of the seat belt guide anchor can be reduced. In particular, in the seat belt guide anchor of the present invention, the surface of the coating resin does not need to be plated, and no slip piece, which is a low friction material, is provided. Can be further reduced.
