Abstract:
A weather strip for attachment to a window frame of a vehicle for contacting a surface of the window for sealing a periphery of the window, wherein the weather strip guides the window while allowing the window to slide upward and downward with respect to the window frame, the weather strip comprising:a front side section for attachment to a generally vertical front member of the window frame;a rear side section for attachment to a generally vertical rear member of the window frame;an upper section for attachment to a generally horizontal member of the window frame, the upper section being located between the front and rear side section;a front corner section for attachment to a front corner of the window frame;a rear corner section for attachment to a rear corner of the window frame;a first seal lip extrusion for resiliently contacting an inner surface of the window;a second seal lip extrusion, extending to the first seal lip, for resiliently contacting an outer surface of the window;wherein the first seal lip continuously forms part of and is coextensive with the side sections, the lip extrusion varies from a first shape along the rear side section to a second shape along the upper section such that the first seal lip has different sealing characteristics along the rear side section as compared to the sealing characteristics of the upper section, wherein a transition shape between the first shape and the second shape is formed in the corner sections;wherein the difference in the sealing characteristics is defined by the rigidity difference of the first seal lip; anda base extending along the entire length of the weather strip, the base including a first outward facing side for contacting the window frame and a second inward facing side, the second side including an inner side wall and an outer side wall projecting from the second side, wherein the side walls are spaced apart from each other, wherein the first seal lip projects from and is integrally formed with the inner side wall and the second seal lip projects from and is integrally formed with the outer side wall, wherein the base, the side walls, the first seal lip, and the second seal lip are elements of a single continuous member.
