Toyoda Gosei Develops Glass Run with New Structure for Improved Automobile Design Characteristics and Quietness

Kiyosu, Japan, October 19, 2017: Toyoda Gosei Co., Ltd. has developed glass runs with a new structure that will contribute to both achieving a more stylish appearance and quieter vehicle cabins. This product is used on the new Lexus LS. 

Glass runs are plastic* sealing products fitted to automobile window frames. They prevent noise, rain and wind from entering the vehicle cabin by plugging the gap between the glass and window frame. They also help windows to open and close smoothly.

Conventional glass runs have a square U shape that holds the edge of the window glass and forms a seal, creating a surface offset between the glass surface and center pillar. The design of the new product has been modified to change the cross-sectional shape and eliminate that offset. This gives a seamless, unified look to the front and back side window glass, contributing to a stylish exterior befitting a premium sedan. At the same time, it reduces the wind noise generated by the surface offset for a quieter vehicle interior cabin.

This new glass run has won the CE Special Award from Toyota Motor Corporation.

Toyoda Gosei sees increasing needs for sound insulating performance with the advance of electric vehicles, and will continue to develop new products for comfortable vehicle cabin spaces.

*Made of thermoplastic olefin (TPO), which has elastic body properties similar to rubber at normal temperatures and can be molded.
