[0069] Figures 1 to 4 The first embodiment of the present invention is illustrated.

[0070] figure 1 (A) and (B) show the back door opening 3 of the ordinary two-box car 1 in the state where the back door 2 is opened. Reference numeral "1a" denotes a roof, reference numeral "1b" denotes a pillar portion at the rear of the vehicle, and a back door 2 is supported by a hinge 2a (indicated by a dotted line) so as to be openable and closeable near the rear end portion of the roof 1a.

[0071] Such as figure 1 As shown in (B), the opening edge of the back door opening 3 is bounded by a combination of four side parts (4a, 4b, 4c) and four corner parts (5a, 5c). The four side parts include: a roof side part 4a extending approximately horizontally along the upper edge of the back door opening 3; a pair of left and right pillar side parts 4b extending in the vertical direction along the pillar part 1b and the floor side portion 4c extending substantially horizontally along the l...

[0098] Figure 5 Shown are a front door opening 31 and a rear door opening 32 of a four-door truck-type vehicle 30 in a state where the front doors and rear doors are removed. 30a represents a front pillar portion at the front of the vehicle, and 30b represents a center pillar portion (also called 30c represents the rear pillar portion at the rear of the vehicle. Front and rear doors (not shown) are supported by hinges 33 and 34 (identified by dashed lines) to enable opening and closing. The weather strip 40 according to the second embodiment is installed over the entire circumference of the opening edge of the front door opening portion 31 .

[0099] Such as Image 6 As shown in (A), the opening edge of the front door opening portion 31 is bounded by a combination of four side portions (31a to 31d) and four corner portions (31e and 31f). The four side portions include: a roof side portion 31a extending approximately horizontally along the upper edge of the front door openi...

Abstract

Provided is an automobile seal material that achieves both the ensuring of seal performance and excellent door closing performance. A seal material (for example, a weatherstrip 6), which seals the space between a vehicle body opening (3) and a door body (2), has, in a cross section thereof, a fitting part that is fit to a flange part provided along an opening edge of the vehicle body opening and aseal part that is integrated with the fitting part. The seal material (6) is formed in an elongated shape, and has, in a longitudinal direction thereof, a first part (P1) that has a first sectional shape, a second part (P2) that has a second sectional shape, and a third part (P3) that connects the first and second parts to each other in a continuous and integrated manner. The sectional shape of the seal part in the second sectional shape is smaller than the sectional shape of the seal part in the first sectional shape, and the third part (P3) is formed such that the sectional shape thereof changes in the longitudinal direction.

Description

technical field [0001] The present invention relates to a sealing member and its attachment structure, and in particular, to a weather strip as a sealing member attached to an opening edge of a vehicle body opening portion of a vehicle and its attachment structure. Background technique [0002] Generally, in a vehicle such as an automobile, an opening edge for closing a vehicle body opening (for example, a side door opening, a back door opening, a trunk opening, etc.) and a door capable of closing a vehicle body opening (for example, The gap between the peripheral parts of the side door, back door, trunk lid, etc.) is provided with a weather strip as a sealing member. However, with regard to the weather strip, in the prior art, various problems to be solved have been raised in order to improve usability. [0003] For example, Patent Document 1 discloses a method and structure for reinforcing a bent section of a hollow weather strip. In Patent Document 1, the cross section ...
