ABSTRACT:
A weather strip to be installed, for example, at the peripheral section of a door of an automotive vehicle. The weather strip is made of elastomeric material and comprised of a general section fabricated by extrusion and a molded section fabricated by molding. The general and molded sections are joined at their end portions with each other by so-called thermal fusion bonding thereby to form the weather strip into an elongated endless shape. The general section corresponds to a straight portion of the weather strip, whereas the molded section is generally L-shaped and corresponds to a curved corner portion of the same. Each of the general and molded sections includes a hollow sealing portion to be brought into contact with a seal-required door opening peripheral surface of a vehicle body. The inner surface of the sealing portion defines a hollow portion. Additionally, a bead is formed on the inner surfaces of the general and molded section hollow sealing portions in such a manner as to extend over the general and molded sections, thereby effectively increasing the strength of the weather strip at a joint section between the general and molded sections.
