Description

  The present invention relates to a weather strip that is attached to a hood of a convertible vehicle in which a roof of a vehicle body is covered with a foldable hood along a hood side edge.

  FIG. 4 shows a convertible vehicle 1 in which a roof is covered with a foldable hood 2, and a frame (not shown) is attached to both sides of the hood 2 so as to be divided into a plurality along the hood side edge. At the same time, the weather strip 3 is divided and attached to each frame. Each weather strip 3 includes an extrusion molding portion 3a and mold molding portions 3b at both ends thereof. When the hood 2 is closed and the roof is covered, the weather strip 3 is connected in series, and in each connection portion, The mold forming portions 3b are pressed against each other and are in close contact with each other, so that sealing between the weather strips is performed.

  FIG. 5 shows a part of the weather strip 3. In the figure, the triangle symbol is the same in the following drawings, and the black-painted side is the mold forming part 3b, and the non-painted side is the extrusion-molded part 3a. As shown in the figure, a positioning block 4 is formed at the end of the molded part 3b.

6 shows a cross section taken along the line 6-6 in the molding part 3b of FIG. 5, and FIG. 7 shows a cross section taken along the line 7-7 in the positioning block 4. The weather strip 3 is screwed onto a frame (not shown). A base 6 attached to the retainer 5 that is fixed by being fixed; a hollow seal portion 8 that forms a hollow portion together with the base portion 6 and seals between the window glass 7 that is raised and closed; and the base portion 6 A hood seal portion 9 that is integrally formed or mounted on a frame and assembled to a base 6 and elastically contacts a hood side edge to seal between the hood 2 as disclosed in Patent Document 1 below. have.
Japanese Patent Application Laid-Open No. 2004-149012

  When the weather strip 3 is assembled, the positioning block 4 is attached to the retainer 5 by pushing the base 6 into the retainer 5 with the positioning block 4 attached to the retainer end surface, and the positioning block 4 is abutted against the retainer end surface. The weather strip 3 is positioned at a predetermined position. However, since the hood seal portion 9 has no positioning means, the hood seal portion 9 pressed against the hood side edge 2a is displaced in the longitudinal direction with respect to the hollow seal portion 8. The end of the hood seal portion 9 may protrude or retract from the positioning block 4, and if it protrudes, it interferes with the hood seal portion 9 of the mating weather strip to close the hood 2 If it is hindered or retracted, a gap will be formed between the hood seal portion 9 of the other party's weather strip and the sealing performance will be impaired.

  An object of the present invention is to provide a weather strip that solves the above-mentioned problems by allowing a hood seal portion to be attached at a predetermined position.

  The weather strip of the present invention is attached to a retainer that is divided and attached to both sides of a foldable hood covering the roof of the automobile body along the side edge of the hood. The weather strip is integrally formed with a base portion mounted on the retainer, a hollow seal portion that forms a hollow portion with the base portion, and seals between the window glass that is raised and closed, and the base portion or the hollow seal portion. Alternatively, it has a hood seal portion that is assembled and extended to the base portion or the hollow seal portion, and elastically contacts the hood side edge to seal between the hood. The weather strip also has a molded part at its end, and a positioning block is formed on the molded part to engage the retainer end surface and perform positioning when the weather strip is attached. A locking portion is provided on one of the positioning block and the end of the hood seal portion, and a locked portion on which the locking portion is detachably locked is provided on the other side. When the stop portion is locked, the end of the hood seal portion is positioned.

  As the locking portion and the non-locking portion in which the locking portion is detachably locked in the present invention, for example, a protrusion or a protrusion formed on one of the block and the hood seal portion and the other are formed. , A groove or a recess in which the protrusion or protrusion is removably locked, a side end surface of the block, a contact surface of the hood seal portion that contacts the side end surface, an edge of any one of the block or the hood seal portion, and Examples include a step fitted to the edge.

  According to the weather strip of the present invention, the hood seal portion is positioned by locking the locking portion and the locked portion with respect to the positioning block that is positioned by being engaged with the retainer end surface. As a result, the end of the hood seal does not protrude or retract from the positioning block.Therefore, it interferes with the hood seal part of the weather strip of the other party connected in series, causing trouble when closing the hood. It is possible to solve the problem that a gap is formed between the sealing portion and the sealing performance is impaired.

  FIG. 1 shows a weather strip 11 according to the present invention, and FIG. 2 shows a state where the weather strip 11 is attached to a hood side edge. FIG. 3 shows a cross section taken along line 3-3 in the molding part 11b of FIG. 2, and the extrusion molding part 11a has the same sectional shape. In the figure, the same reference numerals are given to the same structural portions as the weather strip 3 in FIGS.

  As shown in FIG. 3, the weather strip 11 has a base portion 13 attached to the retainer 12 and a hollow portion together with the base portion 13, and is raised and sealed to the edge of the closed window glass 7. The hood seal part 15 includes a hood seal part 15 that is fitted to the hollow seal part 14 and the bent attachment part 12 a formed integrally with the retainer 12 and is formed integrally with the hollow seal part 14. It has a lip piece 16 that contacts and seals and a lip 17 that elastically contacts and seals the hood side edge 2a.

  A positioning block 18 is formed at the end of the mold forming portion. When the weather strip 11 is attached, the weather strip 11 is positioned by abutting the block 18 against the end surface of the retainer. As shown in FIG. 1, a V-groove engaged portion 19 is formed, and the hood seal portion 15 has an engaging portion 21 having a V-shaped cross section at a portion facing the engaged portion 19. Is formed. In the state where the engaging portion 21 is fitted and locked to the engaged portion 19, the end surface of the hood seal portion 15 is substantially flush with the positioning block 18.

  When the weather strip 11 of the present embodiment is assembled to the hood side edge 2a, the hood seal portion 15 is inserted into the mounting portion 12a with the engaging portion 21 fitted and locked to the engaged portion 19, and the base portion. 13 may be attached by being pushed into the retainer 12, or after the hood seal portion 15 is inserted into the attachment portion 12a and the base portion 13 is pushed into and attached to the retainer 12, the engaging portion 21 is engaged with the engaged portion 19. It may be stopped.

  According to the weather strip 11 of the present embodiment, by engaging and locking the engaging portion 21 to the engaged portion 19, the end surface of the hood seal portion 15 is substantially flush with the block 18 as described above. When the hood 2 is closed and the roof of the vehicle body is covered, the end surfaces of the hood seal portion 15 do not interfere with each other, and the weather strip 11 is formed without any gap between the end surfaces of the hood seal portion 15. Will be connected to.
