Abstract

(57) [Abstract] [Purpose] To reduce the door closing force and improve the sealing performance around the door glass in an automobile having a removable roof. In the abutting portion C where the end of a weather strip 7A attached to the side edge of the removable roof 3 abuts against a weather strip 6A attached to the opening edge of the opening extending from the side surface of the vehicle body to the roof, Thin portions 621 and 721 are formed at positions of the abutting surfaces 62 and 72 of the weather strips 6A and 7A on the pressing side of the door glass 8 to reduce the reaction force of the abutting surfaces 62 and 72 against the pressing of the door glass 8. It has a structure.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a weather strip for an automobile, and more particularly to a weather strip for a roof opening type automobile.

[0002]

[Prior art]

 As a vehicle that gives an occupant a feeling of openness, there is a type in which an opening 10 of a roof 1 is connected to an opening 20 of a door 2 on a side surface of a vehicle body and a removable roof 3 is provided in the opening 10 of the roof 1, as shown in FIG. . In this type of vehicle, weather strips 6A are mounted in series from the center pillar 4A along the rear edge of the opening 10 and weather strips 6B are mounted in series from the front pillar 4B along the front edge of the opening 10. However, the weather strips 7A and 7B are attached to the detachable roof 3 along both left and right edges, and when the detachable roof 3 is attached, both ends of the weather strips 7A and 7B are substantially perpendicular to the weather strips 6A and 6B. A seal structure that abuts against is used.

FIG. 1A shows one of the abutting portions (C portion in FIG. 4). Both weather strips 6A and 7A have a hollow shape, and the abutting portion C has an upper end of a door glass 8. The corners are pressed. FIG. 5 shows a horizontal cross section along the line BB of FIG. 1 (A) in the abutment of the conventional weather strip.

[0004]

[Problems to be solved by the device]

 By the way, since the abutting surfaces 62 and 72 of both weathers trips 6A and 7A overlapping at the abutting portion (hereinafter, the abutting portion C will be described) are substantially vertical to the pressing of the door glass 8, The reaction force against the door glass 8 is large, which causes an increase in the door closing force. In addition, if the reaction force is locally large, the sealing property also deteriorates. Therefore, it is conceivable to reduce the thickness of the entire abutting surfaces 62 and 72, but if the thickness is reduced, the abutting surfaces 62 and 72 will be deformed when the detachable roof is attached, and the adhesion will be impaired. In reality, the mating surfaces 62 and 72 are made thicker than the other portions.

Therefore, the present invention has an object to reduce the door closing force while preventing the deformation of the abutting surfaces 62 and 72 when they are abutted.

[0006]

[Means for Solving the Problems]

 As shown in FIG. 1, the present invention locally forms thin portions 721 and 621 on the abutting surfaces 72 and 62 of the weather strip 7A attached to the removable roof and the weather strip 6A attached to the opening edge of the vehicle body. To do. These are formed on the abutting surfaces 721, 621 on the side where the door glass 8 is pressed and at the position facing the peripheral edge thereof.

[0007]

[Action]

 When the door glass 8 is closed and the abutting portion C is pushed by the peripheral corner portion of the door glass 8, the abutting surfaces 62 and 72 are bent by the thin portions 621 and 721, so that the door closing force is increased. Is prevented. Further, since the thin portions 621 and 721 are a part of the abutting surfaces 62 and 72, no deformation occurs when the abutting surface 621 is pushed into the abutting surface 721 and abutting.

[0008]

【Example】

 An embodiment of the present invention will be described with reference to FIGS.

A weather strip (hereinafter, referred to as a body weather strip) 6A is attached in series from the center pillar 4A to the rear edge of the roof opening 10 for attaching and detaching the roof 1. On the other hand, a weather strip (hereinafter referred to as a roof weather strip) 7A is also attached to the side edge of the removable roof 3. When the removable roof 3 is mounted in the opening 10, the rear end of the roof weather strip 7A abuts on the body weather strip 6A.

An attachment portion of the body weather strip 6A to the pillar 4A has an air seal portion 61 reaching the abutting portion C. The roof weather strip 7A has a hollow seal portion 71, and the end is closed to form an abutting surface 72. The seal portion 61 of the body weather strip 6A is slightly bulged at the abutting portion C, and forms a substantially flat abutting surface 62 that abuts the abutting surface 72. Then, the upper edge corner edge of the closed door glass 8 is pressed against the substantially right-angled abutting portions C of both weather strips 6A and 7A.

On the terminal abutting surface 72 of the roof weather strip 7A, a thin portion 721 is formed at a position above the outside of the vehicle where the corner edge of the door glass 8 is pressed. Further, a thin portion 621 is formed on the abutting surface 62 of the body weather strip 6A at a position corresponding to the thin portion 721. In the illustrated example, one thin-walled portion 621, 721 is formed on each of the abutting surfaces 62, 72, but a plurality of thin-walled portions may be formed.

When the door glass 8 is pressed against the abutting portions C of both weather strips 6A and 7A when the door is closed, the abutting surfaces 62 and 72 are bent by the thin portions 621 and 721, so that the abutting surfaces are abutted. The reaction forces of 62 and 72 are small, and the door closing force hardly increases. Further, in the abutting portion C, there is no portion where the reaction force is locally large, so that the door glass sealing property is also improved. Since the thin portions 621 and 721 are a part of the abutting surfaces 62 and 72, the abutting surfaces 62 and 72 do not deform irregularly when the removable roof is attached.

[0013]

[Effect of device]

 In the weather strip that seals around the door glass with the body weather strip attached to the opening edge of the vehicle body and the roof weather strip that attaches to the left and right side edges of the removable roof and the terminal collides with the body weather strip, By improving the abutting portions of both weather strips, the door closing force can be reduced and the door glass sealing property of the abutting portions can be improved.
