The webbing 52 folded upward from the hanging portion 53 is passed through the insertion hole 83 and guided into the backrest 9. The webbing 52 is guided up and down in front of the support arm 82.

FIG. 3 is a perspective view showing the protective cover 80 from the front side.
As shown in FIG. 3, guide walls 84 and 85 are provided on the front side of the support arm 82 and on both the left and right sides thereof. The guide walls 84 and 85 are rib-shaped and project from the rear surfaces of the base 81 and the support arm 82. The guide walls 84 and 85 extend vertically along the left and right edges of the support arm 82 from the vicinity of the insertion hole 83 to the upper end of the support arm 82. The webbing 52 is guided vertically between the guide walls 84 and 85 along the guide walls 84 and 85.

  Above the insertion hole 83, two guide pins 20 and 30 are attached to the guide walls 84 and 85, and the guide pins 20 and 30 are spanned between the guide wall 84 and the guide wall 85. As shown in FIGS. 2 and 3, the guide pins 20 and 30 are arranged at intervals, and the webbing 52 is passed between the guide pins 20 and 30. When the webbing 52 is sandwiched between the guide pins 20 and 30, the webbing 52 is stabilized. Therefore, flapping of the webbing 52 can be prevented, and the sliding resistance when the webbing 52 is pulled out and rolled up can be reduced.

  4 is a perspective view showing the protective cover 80 from the front side with the guide pins 20 removed. As shown in FIG. 4, the guide pin 20 is formed at a rod-shaped pin body 21, a tip of the pin body 21, a tip 22 having a diameter smaller than the diameter of the pin body 21, and the tips 22. A head portion 23 formed at the opposite end and having a diameter larger than the diameter of the pin main body portion 21;

  On the other hand, a support hole 86 is formed in the guide wall 84, and a through hole 87 is formed in the guide wall 85. The support hole 86 and the through hole 87 are coaxial when viewed from the left or right, and the through hole 87 is disposed at a position opposite to the support hole 86.

  The guide pin 20 is inserted into the through hole 87 from the opposite side of the webbing 52 and the guide wall 84 with respect to the guide wall 85. Specifically, the guide pin 20 is passed through the through hole 87 with the tip end portion 22 first, and the tip end portion 22 is fitted into the support hole 86. The diameter of the support hole 86 is equal to the diameter of the distal end portion 22 of the guide pin 20 or slightly larger than the diameter of the distal end portion 22. Further, the diameter of the pin main body 21 is larger than the diameter of the support hole 86. Therefore, the tip surface of the pin main body portion 21 is caught by the guide wall 84 around the support hole 86. Further, the diameter of the head 23 of the guide pin 20 is larger than the diameter of the through hole 87, and the head 23 is caught by the guide wall 85 around the through hole 87.

  An elastic claw 25 is provided on the opposite side of the webbing 52 and the guide wall 84 with respect to the guide wall 85 and in the vicinity of the through hole 87. The base end 26 of the elastic claw 25 is installed at a position away from the through hole 87, the distal end 27 of the elastic claw 25 is disposed closer to the through hole 87 than the base end 26, and the elastic claw 25 passes through the distal end 27. Oriented towards 87. The elastic claw 25 is inclined with respect to the axial center of the through hole 87 (the axial center of the guide pin 20), and the base end 26 of the elastic claw 25 is larger in diameter than the distal end 27 when viewed in the axial direction of the through hole 87. It is arranged outside in the direction.

  The head 23 of the guide pin 20 is sandwiched between the tip 27 of the elastic claw 25 and the guide wall 85 so that the guide pin 20 cannot be removed from the through hole 87. Further, the elastic claw 25 can be elastically deformed in the radial direction of the through hole 87, and the tip 27 of the elastic claw 25 is separated from the head 23 by the radial load of the through hole 87 acting on the elastic claw 25. Therefore, the guide pin 20 can be extracted.

  Like the guide pin 20, the guide pin 30 is prevented from coming off by the elastic claw 35. Since the guide pin 30 and the elastic claw 35 are provided in the same manner as the guide pin 20 and the elastic claw 25 except for their installation positions, detailed descriptions of the guide pin 30 and the elastic claw 35 are omitted.

Next, a method for arranging the webbing 52 will be described.
First, the tip of the guide pin 30 is inserted into the through hole of the guide wall 85 first, and the guide pin 30 is prevented from coming off by the elastic claw 35 (see FIG. 6). The method for attaching the guide pin 30 is the same as the method for attaching the guide pin 20 to be described later, and a detailed description thereof will be omitted here.

  Next, the webbing 52 is pulled out from the retractor 51, the webbing 52 is passed through the insertion hole 83 of the protective cover 80, and the webbing 52 is guided between the guide walls 84 and 85 along the guide walls 84 and 85 (see FIG. 4). . Then, the webbing 52 is hung on the hanging parts 53 and 54, and the front end of the webbing 52 is connected to the rear end part of the flange receiving part 8.

  Next, as shown in FIGS. 4 and 7, the guide pin 20 is inserted into the through hole 87 with the tip 22 of the guide pin 20 first. As the guide pin 20 is inserted, the head 23 comes into contact with the elastic claw 25. Further, when the head 23 is pushed in and the guide pin 20 is inserted into the through hole 87, the elastic claw 25 is pushed by the head 23 and intersects the axis of the guide pin 20 (the diameter of the through hole 87. Direction) is elastically bent. Thus, when the distal end portion 22 of the guide pin 20 is inserted into the support hole 86, the head portion 23 is detached from the distal end 27 of the elastic claw 25 toward the guide wall 85. Then, the elastic claw 25 is released from being pushed by the head 23 of the guide pin 20, and the elastic claw 25 is restored (see FIG. 5). Therefore, the head 23 is sandwiched between the tip 27 of the elastic claw 25 and the guide wall 85 at the edge portion. Further, the head 23 is caught by the guide wall 85 around the through hole 87 (see FIG. 5). This prevents the guide pin 20 from coming off.

  Next, the belt covers 55 and 56 are attached to the side seat back frame 4, and the support arms 82 of the protective cover 80 are attached to the belt cover 56.

  As described above, according to the present embodiment, the elastic claw 25 is pushed by the head portion 23 of the guide pin 20 and elastically deformed simply by inserting the guide pin 20 into the through hole 87. When the guide pin 20 is fully inserted, the elastic claw 25 returns to its original position and the guide pin 20 is prevented from coming off. Thus, it is possible to achieve both prevention of the guide pin 20 from being detached and simple installation of the guide pin 20. The same applies to the guide pin 30.

  Moreover, since the two guide pins 20 and 30 are attached to one member (protective cover 80), the positional relationship between the guide pins 20 and 30 is stabilized, and the webbing 52 can be stably guided. That is, if the two guide pins 20 and 30 are attached to separate members and these members are attached to the side seat back frame 4, the positional relationship between the guide pins 20 and 30 is not stable due to a design error. In this case, the guide pins 20 and 30 may approach each other, and the parallelism of the guide pins 20 and 30 may decrease, and the webbing 52 may flutter and slide resistance may occur. On the other hand, in this embodiment, since the two guide pins 20 and 30 are attached to the protective cover 80 in advance, and then the protective cover 80 is attached to the belt cover 56, the occurrence of such problems can be suppressed. .

  The embodiments to which the present invention can be applied are not limited to the above-described embodiments, and can be appropriately changed without departing from the spirit of the present invention.
