Abstract

A weather strip formed from at least two materials having distinct physical properties and a corresponding glass run channel. In particular, the weather strip includes a base portion and two sidewallslocated on opposite edges of the base portion. The base portion and sidewalls each include a strip of first material and joints between the base portion and the sidewalls each include a strip of second material more flexible than the first material. The weather strip further includes at least one projection and the glass run channel includes at least one opening for establishing a press fit engagement with the at least one projection. In addition to the first two materials, the weather strip may also be formed of an additional third material having a low friction index and located to come into direct contact with a windowpane. The weather strip is co-extruded out of the first and second materials.
