Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an upper body structure of an automobile, and more particularly to an upper body structure of a canvas stop vehicle whose roof can be opened.

(Prior art and its problems) There are two types of canvas-top vehicles whose roofs can be opened: one in which the roof canvas is opened and closed using a pinion rack, as disclosed in U.S. Pat. No. 3,658,378, and one that opens and closes by pulling a cable. There are also methods of operation.

Cable traction type cable traction methods include 2nd to 4th
There is one shown. That is, the roof is opened and closed by moving the canvas 2 that covers the roof opening 1 along the rail members 5, 5 provided on both sides of the opening 1. An appropriate number of top frames 3 are provided at predetermined intervals in the direction, and link brackets 4 are fixed to both ends of each top frame 3, respectively.

The link brackets 4 are alternately installed with a link bracket 41 movably engaged with a rail 5 extending in the longitudinal direction of the vehicle via a guide shoe 6, and a link bracket 42 in a free state with respect to the rail 5. As shown in the figure, a pair of adjacent link brackets 41 and 42 are connected by a link 7 and a return spring 8.
Further, a traction cable 9 connected to the guide shoe 6 by the plate 10 is guided by the rail 5, and when the link bracket 41 is moved in the opening direction (rightward in FIG. 4) by the cable 9, The link bracket 42 in the free state is moved upward via the link 7 by the biasing force of the return spring 8, so that the canvas 2 is folded into a bellows shape.

The rail 5 is mounted on a support frame 14 bolted between a roof panel 12 attached to the upper surface of a flange portion 11c of a roof rail 11 consisting of an outer rail 11a and an inner rail 11b, and a fixing bracket 13 fixed to the inner rail 11b. is set up.

On the other hand, both side edges of the canvas 2 are adapted to slide on the roof molding 16 along the cable 9 on the outer circumferential track via an outer seal 17 provided at the tip of the support frame 14, The gap between the tip 3 and the support frame 14 is sealed with an inner seal 18.

In addition, in Figures 2 to 4, 19 is the door glass, 20
is the door sash, 21 is the door weather strip,
22 is a bolt protector bolted and fixed to the fixing bracket 13, and 23 is an inner lining.

However, in the conventional configuration described above, since the edge of the canvas is located above the inside of the roof rail,
It is not always easy to ensure waterproof sealing performance between the edge of the canvas and the roof rail, and it is necessary to completely prevent water from entering the side of the car body during high-speed car washes and water droplets remaining in the seal area when opening and closing the canvas and falling into the interior. However, there are problems that cannot be prevented. In particular, when the tension of the canvas is increased to prevent the canvas from flapping or waving, the sealing performance is extremely degraded.

(Purpose of the invention) In view of the above-mentioned circumstances, the object of the present invention is to provide a canvas stop structure for an automobile that can reliably prevent rainwater from entering between the edge of the canvas and the roof rail.

(Structure of the invention) Therefore, in the upper body structure of an automobile according to the invention, both side edges of the canvas support frame are extended beyond the roof rail flange to the outer surface area of the roof rail, and a recess is formed by bending along the roof rail flange. The water that has entered through the gap between the edge of the canvas and the support frame is guided by the bent recess and released in the longitudinal direction of the vehicle, and an elastic body is also provided between the bent recess of the support frame and the roof rail flange. The structure is such that water and sound are prevented from entering through the gap between the support frame and the roof rail.

(Embodiment of the invention) In the first illustrated roof opening side edge structure, a fixing bracket 13 shorter than the conventional one is fastened to the inner rail 11b of the roof rail 11. A support frame 31 supporting the guide rail 5 is bolted and fixed at its horizontal side 31a. Further, the support frame 31 extends from the upper end of the vertical side portion 31b to the flange portion 11c of the roof rail 11 and the outer rail 1 following the flange portion 11c.
1a with a predetermined clearance, and extends to the upper surface of the roof rail 11 and is fixed with bolts. An outer seal 32 is attached to seal the gap. Also, the upper end of the vertical side 31b and the canvas 2
An inner seal 34 is installed between the inner seal 34 and the outer seal 32 to form a double seal structure.

Further, the roof rail 11 is attached to the extending portion 31c.
A recessed portion 31d is formed along the flange portion 11c, and ends of the recessed portion 31d in the longitudinal direction of the vehicle are communicated with in-pillar drainage pipes (not shown) to form a rain rail.

Furthermore, an elastic body 33 is interposed in a clearance area between the recessed portion 31d and the flange portion 11c of the roof rail 11.

On the other hand, the side edge of the canvas 2 extends beyond the roof rail flange portion 11c to a position further outward than the extension portion 31c of the support frame 31, and slides onto the outer periphery of the outer rail 11a via the outer seal 32. are in contact with each other.

In FIG. 1, the same components as those in the conventional example shown in FIGS. 2 to 4 are given the same reference numerals, and their explanations are omitted. Furthermore, although the above description has been made with reference to the side edge structure on one side of the vehicle, it goes without saying that the side edge structure is
It is used on both sides of the vehicle.

In the configuration as described above, since the roof panel is omitted and the support frame 31 is directly fastened onto the roof rail 11, the support frame 31 is shifted toward the roof rail 11 side compared to the conventional structure, and the roof opening width is expanded. I can do it.

In addition, since the edge of the canvas 2 side is extended beyond the roof rail flange portion 11c to the side of the vehicle, the gap between the edge of the canvas 2 side and the roof rail 11 opens downward, resulting in a structure that prevents rainwater from entering. Therefore, even if the tension of the cable 9 is increased and the canvas 2 floats to some extent, the sealing performance will not particularly deteriorate.

Furthermore, even if water were to enter through the outer seal 32, it would not enter the vehicle interior because it would be guided to the pillar drainage pipe (not shown) by the recess 31d functioning as a rain rail. Further, the elastic body 33 installed within the clearance between the recess 31d and the flange portion 11c of the roof rail 11 performs a soundproofing function that blocks external noise from entering the vehicle interior.

(Effects of the invention) According to the canvas stop structure for an automobile according to the invention as described above, the gap between the edge of the canvas and the roof rail is opened downward, and the recess formed in the support frame is Since it functions as a rail, it can maintain its sealing performance even when the tension of the canvas is increased, and
The elastic body installed in the clearance area between the support frame and the roof rail flange provides a soundproofing effect.
