  • Patent number: 6751908
    Abstract: A weather strip for a sliding type rear door is applied to a car which is unfurnished with a center pillar, and is furnished with a front door turnable about hinges provided at the front end thereof and with a sliding rear door which slides back and forth. The weather strip is attached to the front end of the rear door and includes a tapered lip portion extending toward the front door. The tapered lip portion is formed on a molded portion of the weather strip formed at the upper end portion thereof. The tapered portion elastically contacts an opening seal attached to a roof side of a car body and a weather strip attached to a rear end of the front door when the rear door is closed. A guide portion is formed at the lower half of the lip portion. The guide portion is thicker than the lip portion, and it contacts the opening seal and the front door weather strip immediately before the tip end of the tapered lip portion contacts the opening seal and the front door weather strip.
