Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sealing structure for an automobile, and in particular to a weather strip for sealing a center pillar and the door glass of the front and rear doors.

[Prior Art] In automobiles, a weather strip is attached to the center pillar to seal between the front and rear door glass. The center pillar is a combination of a flat plate on the inside and a chevron-shaped plate on the outside. , fitted with a pair of hollow rubber or plastic weather strips. When the front and rear doors are closed, the edges of the front and rear doors come into contact with each weather strip, causing the weather strip to elastically deform, creating a seal between the center pillar and the door glass. is maintained.

[Problems that the invention aims to solve] However, in the past, in order to seal between the center pillar and the door glass of the front and rear doors, the weather strip was divided into two parts, front and rear, and an opening was created where the two weather strips on the outside met. This was not only unsightly in appearance, but also made it impossible to reduce the distance (gap) between the opposing edges of the front and rear door glass in terms of processing and assembly, resulting in problems with watertight sealing characteristics.

In addition, the weather strip is divided into two parts,
The assembly work is cumbersome because it needs to be attached to the center pillar via a retainer.

The weather strip according to the present invention to solve the above problems is a weather strip attached to the outer surface of the center pillar for sealing the center pillar and the door glass of the front and rear doors. A U-shaped attachment part is formed on the inside of the center pillar to be fitted from the outside to the inside on a protrusion protruding outward from the center part of the outer surface of the center pillar, and a U-shaped fitting part is formed to be fitted from the outside to the inside. This feature is characterized in that a hook portion is formed on the trim to be attached to the outer end portion of the weather strip.

[Example] An example of the present invention will be described with reference to the drawings.

As shown in Figure 1, the weather strip of the present invention is installed on the center pillar 1 of an automobile, on the front and rear doors 2,
In order to seal between the door glasses 2a and 3a, the center pillar 1 is installed between the center pillar 1 and the edge portions of the door glasses 2a and 3a. As shown in FIG. 2, the center pillar 1 has an inner plate 1a with a substantially flat cross section on the inside and an outer plate 1b with a trapezoidal cross section on the outside. Flanges 1c, 1c are formed on the outer plate 1b, and a protrusion 1d protrudes vertically outward from the center of the trapezoidal portion of the outer plate 1b. A weather strip 4 according to the present invention is attached to the outer plate 1b and the protrusion 1d. The weather strip 4 is a core bar 4 that is fitted onto the protrusion 1d.
A U-shaped central attachment part 4b with a inside, solid rubber or plastic inner attachment parts 4c extending along the outer plate 1b in the front-rear direction from the U-shaped opening end of the central attachment part 4b, and the inner attachment part 4c. Hollow solid rubber or plastic outer end portion 4 formed at the ends of 4c and 4c
d, 4d, an outer portion 4e made of sponge-like rubber or soft foamed synthetic resin, connecting the outer end portions 4d, 4d and the U-shaped bent portion of the central attachment portion 4b;
4e, and a mounting portion 4f of the molding 5 which extends outward from the U-shaped bent portion of the central mounting portion 4b and is coupled to the recess between the outer portions 4e, 4e. In addition, flange 1c of center pillar 1,
Trims 6, 6 are fitted to 1c, and these trims 6, 6 are provided with hooks 6a, 6a, and the hooks 6a, 6a are attached to the outer end portion 4, respectively.
d and 4d, both ends of the weather strip 4 are fixed to the center pillar 1.
Further, tongue pieces 4g, 4g are provided on the outer end portions 4d, 4d.

[Function] When the weather strip 4 having the above structure is attached to the center pillar 1, the front and rear closed door glasses 2a, 3a come into pressure contact with the weather strip 4, causing it to be elastically deformed. door glass 2a,
A pressure corresponding to the elastic deformation is applied between the weather strip 3a and the weather strip 4, thereby ensuring sealing between the indoor and outdoor areas.

[Effect of the idea] By implementing the present invention, the following effects will be achieved.

(a) The distance between the door glasses 2a and 3a is narrowed, and a molding 5 such as a black molding or a light molding is buried between them, and the appearance becomes beautiful and the sealing performance is improved.

(b) Fitting of the central attachment portion 4b to the protrusion portion 1d;
and hook portions 6 to the outer end portions 4d, 4d, respectively.
It becomes easy to attach the weather strip 4 to the center pillar 1, such as attaching the weather strips a and 6a, and the workability of assembly is improved.

(c) In addition, it is possible to prevent theft by using the tongue pieces 4g, 4g.
