Surface treated particulated polymeric matrix for forming an exposed surface of a weatherseal

Abstract

A weatherseal having a particulated matrix, wherein different sections of the matrix are subjected to different surface treatments, thereby providing corresponding different characteristics, such as coefficient of friction, texture, surface roughness or appearance.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT [0002] Not Applicable REFERENCE TO A “SEQUENCE LISTING”[0003] Not Applicable. BACKGROUND OF THE INVENTION [0004] 1. Field of the Invention [0005] The present invention relates to a vehicular weatherseal, and more particularly, to a vehicular weatherseal having an exposed surface defined by a multitude of surface roughness forming particles in a polymeric matrix, wherein one section of the exposed surface is defined by the particles having a first average position relative to the surface and a second section is defined by a different second average position relative to the surface. That is, at least a portion of the exposed surface is treated to locate a number of the particles in an alternative (or predetermined) location in the polymeric matrix. [0006] 2. Background Art [0007] Many vehicles employ windows formed of glass panels, wherein the window may be fi...

AI Technical Summary

Benefits of technology

"The present invention provides a weatherseal for vehicles that has a unique surface texture made up of particles in a polymeric matrix. The matrix has two different surface roughnesses, creating a sealing surface along one section of the matrix and a different appearance along a second section. This allows for the creation of a friction-reducing surface that reduces noise and noise generation when the weatherseal moves relative to a panel. The same particulated polymeric matrix can also be used to create a smooth or textured surface appearance."

Problems solved by technology

The repeated opening and closing of the glass panel places significant stress on the seal between the glass panel and the vehicle.

However, such weatherseals do not provide for the ready opening and closing of the glass panel relative to the seal.

However, the flocking process is relatively complicated.

The complex manufacturing process adds to the cost of the weatherseal.

However, these coatings are typically not as aesthetically pleasing as non coated areas.

While the coating helps reduce friction, the coating complicates the manufacturing process, as the coating must be limited to specific areas of the weatherseal.
