Abstract: A weather strip for an automotive back door includes a seal lip having a hollow therein. An appropriate portion of the outer side of the seal lip is projected toward a direction outward from a vertical direction relative to a seal plane of a vehicle body where the seal lip elastically contacts thereto. The projected portion is wedge-shaped to function as a drain lip.

Abstract: A weatherstrip structure for an automotive vehicle includes a main body and a seal lip. The main body extends between first and second automotive components and retains the first automotive component at its one side. The seal lip extends from the main body between the main body and the second automotive component so as to define a space between the main body and the seal lip. The seal lip is elastically pressed onto the second automotive component so as to seal between the first and second automotive components. At least one elastic member is fixedly provided in the space. The rib member extends between the main body and the seal lip in a direction which is inclined relative to a direction along which a compressive force is applied to the rib member via the seal lip from the second automotive component.

Abstract: A weather strip for sealingly closing a space having an opening edge associated with a cover member. The weather strip comprises a plurality of extruded weather strip segments each having a welt portion sealingly fitted on the opening edge and a hollow sealing portion formed integrally on the welt portion for sealing contact with the cover member. The hollow sealing portion has a flexible wall defining therein a central bore. The flexible wall has vent holes opening into the exterior of the space to communicate the central bore with the exterior of the space. The weather strip also includes at least one joint segment connected between adjacent two of the weather strip segments. The joint segment includes a chamber connected between the central bores of the adjacent weather strip segments and a passage connected to the chamber for discharging water from the central bore to the exterior of the space at the lower end.
