Description
Background of the Invention
The present invention relates to a molding unit for use with an automobile, and more particularly, the invention relates to a molding unit which can perfectly seal a clearance between a windshield and an automobile body and which can be used even when the gap height between the outside surface of the windshield and the outside surface of the roof panel of the automobile body is different from that between the outside surface of the windshield and the outside surface of the front pillar of the automobile body.
The conventional molding unit for use with an automobile generally comprises a molding body which is installed in a clearance between the circumferential edge of the windshield and the automobile body and which has a leg portion to be inserted into the clearance, an outer covering portion contactable with the automobile body and an inner covering portion contactable with the windshield, and fasteners positioned in the clearance and mounted on the body by adhesive or double sided tape. The fasteners engage the leg portion of the molding body to fixedly support the molding body in the clearance.
Such a conventional molding unit is found, for example, in Japanese Laid-Open Utility Model Publication Nos. 63-32915 and 63-32916.
Japanese Publication No. 63-32915 discloses a molding unit of which the molding body has a weir portion to downwardly lead rainwater therealong. The weir portion is formed by partly removing the inner covering portion of the molding body along the front pillar of the automobile body.
A problem usually associated with the prior art molding unit as described in Japanese Publications No. 63-32915 is that such a molding unit is not adaptable when the gap height between the outside surface of the windshield and the outside surface of the front pillar of the automobile body is greater than that between the outside surface of the windshield and the outside surface of the roof panel of the automobile body, because in the molding body corresponding to the front pillar, a clearance is formed between the inner covering portion of the molding body and the outer surface of the windshield, causing entry of rainwater into the clearance between the circumferential edge of the windshield and the automobile body.
Another problem usually associated with the prior art molding unit as described in Publication No. 63-32915 is that the molding body exhibits undesirable awkward appearance because the inner covering member of the molding body is partly removed to form the weir portion.
The Japanese Publication No. 63-32916 discloses a molding unit of which the molding body has a weir member to downwardly lead rainwater therealong. The weir member is independently formed and is bonded to the inner covering portion of the molding body along the front pillar of the automobile body.
A problem usually associated with the prior art molding unit as described in Japanese Publications Nos. 63-32916 is that the molding body requires increased working time to be formed because the weir member has to be independently formed and subsequently has to be bonded to the inner covering portion of the molding body along the front pillar.
Another problem usually associated with the prior art molding unit as described in Publication No. 63-32916 is that the molding body exhibits undesirable awkward appearance because the inner covering member of the molding body is bonded with the weir member along the front pillar.
Summary of the Invention
It is an object of the invention to provide an improved molding unit for use with an automobile, that is, to provide a molding unit which is applicable even when the gap height between the outside surface of the windshield and the outside surface of the roof panel of the automobile body is different from that between the outside surface of the windshield and the outside surface of the front pillar of the automobile body.
It is another object of the invention to provide a molding unit for use with an automobile, that is, to provide a molding unit in which the problem associated with the conventional molding unit is eliminated.
A molding unit of the present invention includes a molding body, a complemental covering member positioned longitudinally along the molding body, and a plurality of fasteners provided on the automobile body for fastening the molding body with the covering member to the automobile body. The molding body has a leg portion and a covering portion integrally provided on the upper portion of the leg portion. The complemental member has a weir portion and a fitting portion which is integrally formed with the weir portion and is adapted to be fitted to the leg portion of the molding body. When the molding body with the complemental member is positioned along the windshield, the covering portion of the molding body is seated on the outside surface of the windshield at the portion along which the complemental member is not positioned and the lower edge of the weir portion of the complemental member is seated on the outside surface of the windshield at the portion along which the complemental member is positioned.
An important feature of the present invention is that the molding body is adaptable even when the gap height between the outside surface of the windshield and the outside surface of the roof panel of the automobile body is different from that between the outside surface of the windshield and the outside surface of the front pillar of the automobile body.
Another feature of the present invention is that the molding body exhibits a good appearance because the configuration of the molding body is uniform throughout the overall length thereof.
The present invention will become more fully apparent from the claims and the description as it proceeds in connection with the drawings.

A molding 10 is installed in a clearance between the edge surface of the windshield 5 and the automobile body 1.
Referring now to FIGS. 1 and 3 to 5, shown therein is a molding unit according to a first embodiment of the invention. The molding unit includes the molding 10 which comprises a molding body 11 and a weir member or complemental member 21, and a fastener 30 to fixedly support the molding 10 on the automobile body 1.
As shown in FIG. 1, the roof panel 1a and the front pillars 1b are interconnected to form arcuate portions C therebetween. The peripheral edge of the roof panel 1a is inwardly folded to form a slanted wall portion 3a and a flanged portion 3. The peripheral edge of each front pillar 1b is also inwardly folded to form a slanted wall portions 43a and a flanged portions 43 which are integral with the wall portions 3a and the flanged portion 3, respectively.
As will be appreciated, the gap height Ha between the outside surface of the windshield 5 and the outside surface of the roof panel 1a is smaller than the gap height Hc between the outside surface of the windshield 5 and the outside surfaces of the front pillars 1b. In other words, the height of the wall portion 3a is lower than that of the wall portions 43a. Therefore, each of the front pillars 1b is formed with an inclined portion 1c through which the roof panel 1a is connected to the front pillars 1b.
The windshield 5 is circumferentially provided with a dam member 4 formed of a rubber or the like and is bonded to the flanged portions 3, 43 with an adhesive 6.
The wall portion 43a of each front pillar 1b is provided with a plurality of fasteners 30, at suitable intervals, with double-sided tape 29. Each of the fasteners 30 has a substantially U-shaped cross-sectional configuration and is formed of resilient material such as rubber and synthetic resin. The fastener 30 has a first and second walls 32, 34 to form a groove 31 therebetween. The first wall 32 of the fastener 30 is provided with a projection 32a projecting into the groove 31 and extending throughout the overall length thereof.

The fitting portion 24 is formed with a flange or projection 26 projecting into the groove 25 and extending throughout the overall length thereof. In addition, the fitting portion 24 is formed with a shoulder portion 27 at the lower end thereof. The lower end of the weir portion 22 is provided with a resilient member 23 formed of material such as rubber and synthetic resin and extending throughout the overall length thereof. Further, the height H of the weir portion 22 is adapted to conform substantially to the gap height Hc-Ha between the roof panel 1a and the front pillar 1b.
The weir portion 22 of the complemental member 21 is formed with an upper inclined surface 22a at a portion corresponding to the inclined portion 1c of the front pillar 1b thereby to be formed with a reduced height portion 22b having a triangular configuration.
