Abstract

Disclosed herein is a glass run having the ability to reduce a rattle while keeping the sliding resistance of a glass windowpane low enough. The glass run includes an exterior lip, an interior lip, and an auxiliary interior lip. A windowpane is inserted between the exterior and interior lips. A soft portion, made of a softer material than the interior lip or auxiliary interior lip, is interposed in a region where the interior lip and the auxiliary interior lip overlap with each other. The soft portion may be provided for at least one of the interior lip and auxiliary interior lip.

First claim

What is claimed is:

1. A glass run for use in motor vehicles, the glass run being mounted to a window frame that supports an outer periphery of a retractable glass windowpane provided for a motor vehicle door such that the windowpane is readily moved up and down with respect to the door, the glass run comprising:
a glass run body including a base, an exterior sidewall extending from a portion of the base closer to outside of a cabin of the motor vehicle, and an interior sidewall extending from another portion of the base closer to inside of the cabin;
an exterior lip extending from the exterior sidewall of the glass run body toward the inside of the cabin so as to approach the base, and coming into contact with an outer surface of the windowpane facing the outside of the cabin;
an interior lip extending from the interior sidewall of the glass run body toward the outside of the cabin so as to approach the base, and coming into contact with an inner surface of the windowpane facing the inside of the cabin; and
an elastically deformable portion protruding from the interior sidewall of the glass run body, and arranged to face an inner surface of the interior lip that faces the inside of the cabin so as to be elastically deformable toward or away from the cabin,
wherein a portion, made of a material that is softer than a material of the interior lip or the elastically deformable portion, is interposed between the interior lip and the elastically deformable portion so as to be located in a region where the interior lip overlaps with the elastically deformable portion when viewed in a vehicle width direction in a state where the windowpane is inserted between the exterior lip and the interior lip.

2. The glass run of claim 1 , wherein:
the elastically deformable portion is configured as a lip protruding from the interior sidewall of the glass run body toward the outside of the cabin and extending obliquely with respect to the interior sidewall, and
the portion forms an integral part of the elastically deformable portion.

3. The glass run of claim 2 , wherein the portion is provided for only a tip end portion of the elastically deformable portion in a its protruding direction.

4. The glass run of claim 2 , wherein:
the inner surface of the interior lip that faces the inside of the cabin functions as a contact surface to contact with the portion, and
the contact surface is curved toward the outside of the cabin.

5. The glass run of claim 1 , wherein the portion forms an integral part of the inner surface of the interior lip that faces the inside of the cabin.
