DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat belt device for restraining an occupant to a seat by webbing, and more particularly, to a seat belt device for preventing a webbing from being caught or taken out of a retractor (winding device). Regarding improvement.

[0002]

2. Description of the Related Art FIG. 26 schematically shows an example of the structure of a seat belt device mounted on a vehicle, including a retractor (winding device) 1, a webbing 2, a through anchor 3, a tongue plate 4, and a buckle 5. Have been. The retractor 1 is usually arranged in a body panel of a vehicle described later,
It has a built-in bobbin (winding shaft) that is urged in the winding direction. One end of the webbing 2 is wound around the bobbin. The other end of the webbing 2 is pulled out of the retractor 1 and folded back by a through anchor 3 rotatably mounted on a center pillar (not shown), and is rotatably mounted on the floor of the vehicle beside the seat (not shown). Attached to anchor plate. A tongue plate 4 is movably provided on the webbing 2. The webbing 2 is mounted (belt mounted) by inserting the locking portion of the tongue plate 4 into the buckle 5 supported substantially on the side of the seat and engaging the same.

FIG. 27 shows an example in which the above-mentioned seat belt device is viewed from the front side of the vehicle. As shown in the figure,
The retractor 1 is attached to a body panel 51 of the vehicle on the side of the seat 6 and is covered with a garnish 52. That is, the lower part of the retractor 1 is fixed to the body panel 51 by bolts and nuts or the like, and the upper part of the retractor 1 is mounted to the body panel by bolts and nuts via the upper stay 11. . The upper stay 11 is fixed to the retractor 1 by a rivet 12 or the like, or is integrally formed. The webbing 2 pulled out from the retractor 1 reaches the through anchor 3 through an outlet 13 formed by a through hole in the upper stay 11. The outlet section 13 is provided with an outlet guide 14 for facilitating the movement (movement) of the webbing 2.

FIGS. 28 to 31 show a webbing outlet 1.
Rubbing of position 3 and webbing 2 (interference with other members)
FIG. Corresponding parts in each drawing are denoted by the same reference numerals.

FIG. 28 schematically shows a cross section of the retractor 1. One end of the webbing 2 is wound around a bobbin 110 rotatably attached to a retractor base 101. In the example shown in FIG. 28, the outlet portion 13 of the webbing 2 is formed on the horizontal flat surface of the substantially “L” and inverted “L” -shaped upper stays 11 on the right side in the drawing. In a state where the webbing 2 is substantially wound around the bobbin 110, that is, in a state where the webbing 2 is stored in the retractor 1, the winding amount of the webbing 2 around the bobbin 110 increases, and the winding start position W of the webbing is shifted to the bobbin 110. In the radial direction. The webbing 2 is drawn tangentially from the winding start position W of the webbing 2 and reaches the outlet portion 13. However, exit 1
A head of a rivet (caulking pin) 12 for fixing the retractor base 101 and the upper stay 11 projects between the winding start position W of the webbing 2 and the webbing 2. Also,
There is also an edge of the retractor base 101.

As a result, as shown in a partially enlarged view of FIG. 29, interference occurs between the webbing 2 and the rivet 12, and between the webbing 2 and the edge of the retractor base 101.
This causes damage to the webbing 2 and increases interference (extraction) resistance of the webbing. The former can cause a decrease in the merchantability and strength, and the latter can cause a decrease in the winding and drawing property.

FIG. 30 shows an example in which the webbing 2 is pulled out obliquely. In this example, the upper stay 11 is formed in a modified “S” shape. The winding start position W of the webbing in the housed state of the webbing 2 (when the webbing is not mounted) is located radially outward, so that the webbing 2 interferes with the head of the rivet 12. Further, the winding start position W of the webbing in the state where the webbing 2 is pulled out (when the webbing is attached) is located radially inward, and the webbing 2 interferes with the upper edge of the head of the rivet 12. The webbing 2 has a retractor base 101.
Also interfere with the upper end of the.

FIG. 31 shows an example in which the position of the outlet portion 13 of the webbing 2 is adjusted so that interference between the webbing 2 and the rivet 12 does not occur.

As described above, in order to prevent the webbing 2 from being damaged or an unexpected increase in interference resistance due to the head of the rivet 12 or burrs (edges) of the retractor base 101, the webbing is provided between the webbing 2 and the rivet. It is preferable that the outlet of the webbing 2 is set in accordance with the vehicle design of the vehicle type so as not to contact (interfere) with an obstacle.

[0010]

However, in recent years, in accordance with the diversification of vehicle body designs, it is desired that the degree of freedom in setting the webbing outlet is wide and the retractor has a high degree of freedom in storage. In addition, it is desired that the winding and pulling properties be better than before. In order to satisfy these demands, it is difficult to change or adjust the position setting of the webbing outlet as in the related art.

Therefore, the present invention has a high degree of freedom in setting the webbing outlet while maintaining the take-up and pull-out properties of the webbing,
An object of the present invention is to provide a seat belt device having a high degree of freedom in storing webbing.

Further, the present invention has a high degree of freedom in setting the webbing outlet while maintaining the winding and pulling-out properties of the webbing,
