Abstract
Official abstract text for this publication.
A weather strip includes an installation base member and a seal member. The installation base member is configured to operably couple to a peripheral edge of a panel. The seal member is integrally molded with the installation base member and configured to make elastic contact with a peripheral edge of an opening in a body of an automobile when the panel is in a closed position. The seal member includes sponge material which has a specific gravity that falls within a range of 0.35 to 0.65 and a loss elastic modulus of not more than 0.25 MPa. More preferably, the sponge material has a loss elastic modulus of not more than 0.20 MPa.
First claim
Opening claim text (preview).
We claim: 1. A weather strip comprising: an installation base member configured to operably couple to at least one of a peripheral edge of a panel and a peripheral edge of an opening in a body of an automobile; and a seal member integrally molded with the installation base member, the seal member being configured to make elastic contact with the other one of the peripheral edge of the panel and the peripheral edge of the opening in the body of the automobile when the panel is in a closed position, wherein the seal member comprises a rubber sponge material having a specific gravity that falls within a range of 0.35 to 0.65 and a loss elastic modulus of not more than 0.25 MPa. 2. The weather strip as claimed in claim 1 , wherein the loss elastic modulus of the rubber sponge material is not more than 0.20 MPa. 3. The weather strip as claimed in claim 2 , wherein the seal member comprises a hollow seal member and has a compression set of not more than 25%. 4. The weather strip as claimed in claim 1 , wherein the seal member comprises a hollow seal member and has a compression set of not more than 25%. 5. The weather strip as claimed in claim 1 , wherein the rubber sponge material mainly includes ethylene-propylene-diene rubber. 6. The weather strip as claimed in claim 1 , wherein the rubber sponge material comprises ethylene-propylene-diene rubber.
