Description

[Detailed Description of the Invention] The present invention is a weather strip retainer (hereinafter simply referred to as a retainer) for attaching a weather strip to the periphery of an opening in a vehicle body, such as a window frame on the side of the vehicle body, to contact the window glass and seal the interior and exterior of the vehicle. (hereinafter referred to as "improvement").

A conventional retainer of this kind will be explained using the roof side part of a satsure-less door vehicle as an example. As shown in FIGS. Screws 40 are fixed at multiple locations via Eptsheera (product name) or Combriband (product name), and hold the weather strip 50 to ensure that the main lip 51 is in contact with the window glass G. This improves the sealing function inside and outside the vehicle.

By the way, focusing on the sealing performance between the retainer 10 and the roof site rail outer panel 21, the screw insertion holes 12 (FIG. 3) formed in the vehicle body mounting surface 11 (hereinafter simply referred to as the mounting surface 11) of the retainer 10 are as follows. Peripheral part 1
3 is deformed as shown in FIG. 3 when the screw 40 is fixed, so the surface pressure on the sealing material 30 is highest at the peripheral edge part 13, and at the part between the fitting holes 12. The surface pressure on the sealing material 30 decreases as the distance from the screw 40 increases.

If the surface pressure varies from part to part in this way, in areas where the surface pressure is high (the part where the screw 40 is located and its surroundings),
The compressive force of the sealing material 30 is large and the sealing performance is good, but the compressive force of the sealing material 30 is small in the area where the surface pressure is low (in the middle of the part indicated by L), and the sealing performance is poor.

Therefore, the sealing function of the sealing material 30 is insufficient in the L portion where the surface pressure is low, and there is a risk that rainwater etc. may infiltrate into the vehicle interior. becomes unstable.

In order to eliminate this unstable sealing performance, it is possible to increase the thickness of the sealing material 30 or increase the number of screws 40, but in the first place the function of the retainer 10 is
Since the function of holding the strip 50 is reliable, it is undesirable to increase the thickness of the sealing material 30 or increase the number of screws 40 in terms of saving materials.

In view of the conventional situation, the present invention provides a retainer that can improve the sealing performance between the retainer and the vehicle body without changing the installation workability or increasing the cost compared to the conventional one. The present invention will be described in detail below using embodiments in which the same parts as those of the prior art are denoted by the same reference numerals.

(1) First embodiment: In FIGS. 4 and 5, the retainer 10 has holding parts 14 that hold the base 52 of the weather strip 50 from both ends of the mounting surface part 11, and I-shaped bead portions 15, 15 are formed on both sides of the fitting hole 12 of the surface portion 11.

The bead portions 15, 15 protrude toward the vehicle body and have their longitudinal directions in the same direction as the longitudinal direction of the retainer.

Furthermore, a drip molding 60 is attached to the outer side end of the mounting surface portion 11 to hide the vehicle body drip channel 22 and improve the decorative effect of the roof side portion.

This configuration provides the following effects.

That is, when the retainer 10 is attached to the roof site rail outer panel 21 via the sealing material 30 with the screws 40, the bead portions 15, 15 bite into the sealing material 30, and the bead portions 15, 15 are attached to the sealing material 30. Increases surface pressure and improves sealing performance at the bead forming site.

Since this bead portion 15.15 is formed over the entire area with the retainer 10, the surface pressure is almost uniform and the stability of the seal is ensured in the entire area between the retainer 10 and the roof site rail outer panel 21. It can be done.

In addition, since both sides of the fitting hole 12 are reinforced by the bead parts 15, 15, the mounting surface portion 11 other than the opening part of the fitting hole 12 is
This prevents a drop in surface pressure and further improves sealing performance.

The distance S1 from the center C of the insertion hole 12 to both bead portions 15, 15. Since S2 is set to approximately 51=S2, the surface pressure on the sealing material 30 by both bead portions 15.15 becomes equal, the sealing force becomes uniform, and stable sealing performance is obtained. Deformation of the peripheral edge of the insertion hole due to attachment can also be suppressed.

(2) Second embodiment: In FIG. 6, only the differences from the first embodiment will be described. In the first embodiment, the retainer 10 and the drip molding 60 are integrated by welding. However, in this embodiment, the outside holding part 14 of the retainer 10 is further extended to form a drip molding part 60' integrally with the drip molding part 60', and a sealing material 31 is applied to the inside part of this drip molding part 60'. After adhering in advance, the drip channel 22 and the retainer drip molding part 60' are sealed with the sealing material 31, and the roof site rail 20 and the retainer 10 are double sealed to obtain a perfect sealing effect. This is what I did.

In the case of this embodiment, the roof site rail 20 and the retainer 1
0 is stable as in the first embodiment,
Of course, the drip molding is integrally molded into the retainer 10, so the number of parts to be installed is reduced, and the sealing material 30 and 31 allows for double sealing, which greatly improves the sealing performance. .
