Glass run channel

摘要

A glass run channel includes a run channel main body including a bottom wall portion, an interior lateral wall portion, and an exterior lateral wall portion, and an interior seal lip and an exterior seal lips. At least one lateral wall portion and the bottom wall portion are formed from a sponge material. At least one lateral wall connecting portion among an interior lateral wall connecting portion and an exterior lateral wall connecting portion is formed from the sponge material thinner than the interior lateral wall portion, the exterior lateral wall portion, and the bottom wall portion so as to be capable of being bent when being mounted on the window frame. An outer peripheral side of the lateral wall connecting portion formed from the sponge material is covered with a covering portion made of a solid material.

主权项

1. A glass run channel mounted on a window frame of a vehicle body so as to guide a movement of a window pane and formed in an elongated shape from a polymer material, the glass run channel comprising:
a run channel main body including (i) a bottom wall portion provided at a position that faces an end surface of the window pane, the bottom wall portion having one end and another end, and (ii) an interior lateral wall portion and an exterior lateral wall portion that respectively extend from the one end and the other end of the bottom wall portion, and formed to have a U-shaped cross-section; and an interior seal lip and an exterior seal lip respectively protruding from ends of the interior lateral wall portion and the exterior lateral wall portion toward the bottom wall portion and capable of coming into elastic contact with respective surfaces of the window pane, wherein at least one lateral wall portion among the interior lateral wall portion and the exterior lateral wall portion is formed from a first sponge material, and the bottom wall portion is formed from a second sponge material, wherein the interior lateral wall portion and the bottom wall portion are connected together by an interior lateral wall connecting portion, and the exterior lateral wall portion and the bottom wall portion are connected together by an exterior lateral wall connecting portion, wherein at least one lateral wall connecting portion among the interior lateral wall connecting portion and the exterior lateral wall connecting portion is formed from a third sponge material that is thinner than the interior lateral wall portion, the exterior lateral wall portion, and the bottom wall portion, wherein an outer peripheral side of the at least one lateral wall connecting portion formed from the third sponge material is covered with a covering portion formed from a solid material, and wherein an outer side of the bottom wall portion, which faces the window frame, is not covered with the covering portion formed from the solid material, wherein an interior holding lip and an exterior hold lip, which respectively protrude from external surfaces of the interior lateral wall portion and the exterior lateral wall portion, are formed, and wherein the covering portion that covers the at least one lateral wall connecting portion formed from the third sponge material and at least one of the interior holding lip and the exterior holding lip, which is adjacent to the covering portion, are integrally formed from the same solid material.
