Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an upper body structure of an automobile, and more particularly to an open top type structure in which at least a rear part of the vehicle body is covered with a hood.

(Prior Art) Conventionally, as an open-top type automobile, it is formed on the rear side of the vehicle body by covering the area from the rear portion of the vehicle body to the roof portion with a hood, and moving the hood rearward as necessary. A so-called convertible type, which can be brought into a fully open state by folding and storing in a storing portion, is generally well known.

Further, in the case of the above convertible type vehicle, when the top of the vehicle body is covered with a hood, the sealability of the joints between the hood and the side and front windows is likely to become a problem. A new open top format has been proposed to solve this problem (UK published patent application No. 2).
086316). That is, this proposal is
A generally inverted U-shaped foldable pillar is mounted between the two side walls of the vehicle body so as to be rotatable in the vehicle front-rear direction centering on both leg ends, and the rear part of the vehicle body behind the foldable pillar is hung from the foldable pillar and attached to the vehicle body. The roof panel is covered with a roof and the roof panel is detachably hung between the top of the retractable pillar and the top of the front window.

By the way, in an open-top type automobile in which the rear part of the vehicle body is covered with a hood as described above, normally, when the hood is stretched, the hood is stretched from the inside toward the outside of the vehicle to prevent flapping of the hood. A U-shaped hood tension link is provided, and when the hood is folded and stored in the storage portion on the rear side of the vehicle body, the hood tension link is stored below the storage portion together with the hood. .

In addition, a rear window is provided in the center of the hood to secure the rear view when the hood is stretched, but when a transparent vinyl material is used for this rear window so that it can be folded like the hood, In addition, since vinyl materials are soft, they are easily scratched, and when folded many times, it becomes cloudy due to scratches and becomes difficult to see, and wrinkles are likely to cause waviness, so flatness is maintained. However, there is a problem that things look distorted. Therefore, glass is usually used as the rear window, and the rear window glass is supported by a window glass frame fixed to a hood.

(Problems to be Solved by the Invention) However, when glass is used for the rear window of the hood as described above, there are the following problems. That is, when the hood is folded and stored in the storage portion on the outside of the vehicle body, the rear window glass drops into the storage portion before the hood tension link that stretches the hood outside the vehicle body around the storage portion. It may slip under the tension link. Therefore, when the hood is stretched again, the hood cannot be stretched smoothly, and the hood may be damaged due to the excessive tension of the hood.

Further, when the hood is stretched, the vicinity of the rear windshield of the hood hangs downward (inward of the vehicle body) due to the weight of the rear windshield or the windshield frame, which makes the appearance worse and causes the hood to flap. There's a problem.

The present invention has been made in view of the above points, and an object thereof is to prevent movement of the rear window glass when the hood is stored to prevent the rear window glass from slipping under the hood link. At the same time, the supporting rigidity of the rear windshield is increased to prevent the hood from hanging down near the rear windshield when the hood is stretched.

Assumption. That is, the hood is positioned at a first position where the hood is stretched and covers the rear part of the vehicle body, and a second position where the hood is moved rearward of the vehicle body and folded and stored in a storage portion formed on the rear side of the vehicle body. The hood is provided so as to be movable between the two positions, and a lower end portion and a rear end portion of a side surface of the hood are fixed to a peripheral portion of the storage portion below an upper opening surface of the storage portion of the vehicle body, and the center of the hood is fixed. A window glass frame supporting a rear window glass is fixed to the portion, and the hood is the first.
When the hood is in the position, the hood is abutted against the inner surface of the hood so as to extend outward from the vehicle body around the upper opening of the storage part, and when the hood is in the second position, the hood is stored below the storage part together with the hood. There is a character-shaped horobari link.

In the upper body structure of the automobile having such a structure, one end side is fixed to the rear lower end of the wind glass frame, and the other end side is moved when the hood moves between the first position and the second position. The set plate is provided with a guide portion that slides in contact with the upper surface of the rear portion of the hoori link.

(Operation) With the above configuration, according to the present invention, when the hood is folded and stored in the storage portion on the rear side of the vehicle body, that is, when the hood is moved from the first position to the second position, the rear portion of the wind glass frame that supports the rear windshield. The set plate fixed to the lower end abuts against the upper surface of the rear portion of the front tension link at the guide portion and slides, whereby the movement of the rear windshield is restricted and the rear portion of the rear windshield slips under the rear portion of the front tension link. Can be prevented.

Further, when the hood is stretched, that is, in the first position, the windshield frame is supported by the hood tension link by the set plate, so that the support rigidity of the rear windshield is increased accordingly, and the rear windshield of the hood is increased. It will be possible to prevent sagging near the glass.

Here, the guide portion of the set plate may be provided with an engaging portion that engages with the hood link so as to prevent the hood from moving upward when the hood is in the first position. It is preferable in terms of preventing the hood from flapping.
