Description

[Detailed Description of the Invention] This invention relates to the structure of interior parts for automobiles, and particularly to the structure of seat belt insertion portions in interior parts such as center pillars and rear corners made of injection molded bodies.

Seat belts are installed in the cabin of a car to restrain the body of the occupants while driving to ensure safety. This seat belt has a retractor installed inside an interior part such as a center pillar or a rear corner, and the webbing of the seat belt is inserted through an opening provided in the interior part, and the webbing is pulled out through the opening when in use. Many types have a structure in which the webbing is pulled in and stored using a retractor when in use. Fig. 1 is a partial perspective view of the exterior of an automobile interior part (center pillar) equipped with this type of seat belt, showing an opening 2 provided in a center pillar 1 made of synthetic resin,
2', and the webbing 3 of the seat belt is pulled out and retracted. 3a in the figure shows the position of the webbing when the seat belt is used.

Figure 2 shows a cross section of the seatbelt webbing insertion part of the center pillar 1.
is the inner side of the vehicle interior, and Y is the inner side of the center pillar. The webbing 3 of the seat belt moves as shown in the figure as the drawer is pulled in, and comes into contact with and slides on the edge of the opening 2. Therefore, in order to avoid damage caused by rubbing of the webbing, the edges of the opening are generally rounded. However, since the interior parts such as the center pillar are injection molded products of synthetic resin, it is not possible to make all the edges of the opening 2 round because of the cutting die. That is, a, b, c, d
One of the four edges (d in the illustrated example)
The chisel must have a square edge. Therefore, the webbing 3 of the seat belt contacts and slides on this corner edge, causing damage. If you want to remove this problem,
After injection molding, the corner edges must be separately cut or polished to give them a rounded shape, but this requires a large number of additional man-hours.

The present invention does not require such extra man-hours,
Furthermore, this invention was made with the intention of providing an automobile interior part that can eliminate the damage to seat belts and webbings as described above. The configuration of the present invention will be explained below based on the embodiments shown in the drawings.

FIG. 3 is a sectional view of a seatbelt/webbing insertion portion of an automobile interior part (center pillar) according to the present invention, and FIG. 4 is a perspective view of the external appearance of the same portion.

As in FIG. 2, of the four edges on the edge of the opening 2 through which the seatbelt webbing 3 is inserted, three edges a, b, and c are round edges, and only d is a corner edge. It's a connection.
In the present invention, a rib 4 is made to protrude from the outer side of the edge d. As seen in FIG. 4, this rib 4 extends along the longitudinal direction of the opening 2 (that is, the width direction of the webbing 3), and protrudes from the surface of the center pillar 1 at an appropriate height. However, the height is such that when the webbing 3 contacts the tip 5, it does not contact the edge d. Further, the tip portion 5 has a rounded edge to prevent damage when the webbing 3 contacts or rubs against it. Note that 4 and 4' indicated by bold lines in FIG. 1 are ribs provided on the outside edges of the openings 2 and 2' of the center pillar 1 according to the present invention.

Since the automobile interior parts of the present invention are constructed as described above, the webbing 3 of the seatbelt opens the opening 2 as the seatbelt webbing 3 pulls out the drawer, pulls in, swings, etc.
Even if the webbing 3 contacts and rubs against the edge of the corner, since all of the contact points are round edges, problems such as the webbing 3 being rubbed against the corner edge and being damaged as in conventional products will not occur. do not have. Therefore, there is no need to replace the webbing due to damage, and there is no danger of the webbing breaking during use.Furthermore, the ribs can be integrally molded when molding interior parts, so they cannot be replaced separately after injection molding as described above. This has many advantages, such as eliminating the need for extra man-hours such as round edge processing in which the corner edges are rounded by cutting or polishing.

In the above description, the rib 4 is referred to as the opening 2.
Of the four edges on the mouth edge, the embodiment has been described in which the ribs 4 are provided on the outer edge of the upper outer edge d, but it goes without saying that the rib 4 may be installed on the outer edge of the lower outer edge a. Nor.
