发明名称 DOOR WEATHERSTRIP FOR MOTOR VEHICLES
摘要 A front door weatherstrip for motor vehicles has a wind-noise suppressing rib formed in a groove portion defined between a hollow sealing lip and a tongue-like sealing lip of the door weatherstrip to serve as a dam against a flow in a longitudinal direction of the groove portion. When these lips are elastically deformed by closing the front door, the wind-noise suppressing rib penetrates into a recess portion of the hollow sealing lip to overlap with the recess portion and to make the flow continuous by a bypass flow through the recess portion. Therefore, the front door weatherstrip is improved in at least drainage property without affecting sealing property and door closure property.

主权项 1. A door weatherstrip for motor vehicles, comprising: a base portion fixed to a portion of a front door of a motor vehicle, the portion being directly above a waist portion of the front door; a hollow sealing lip monolithically formed with the base portion, the hollow sealing lip being in an elastic abutment with a body panel of the motor vehicle when the front door is closed, the hollow sealing lip having a recess portion; a tongue-like sub sealing lip monolithically formed with the base portion to define a groove between the hollow sealing lip and the tongue-like sub sealing lip, the groove joining with the recess portion of the hollowing sealing lip, the tongue-like sealing lip being in an elastic abutment with the body panel when the front door is closed; and a wind-noise suppressing rib projectingly formed at a position in the groove to serve as a dam against a flow in a longitudinal direction of the groove such that, when the hollow sealing lip and the tongue-like sub sealing lip are elastically deformed by closing the front door, the wind-noise suppressing rib penetrates into the recess portion of the hollow sealing lip to overlap with the recess portion and to make the flow continuous by a bypass flow through the recess portion.
