Weatherstrip structure

An elongated elastomeric body suitable for use as a weatherstrip and comprising:

• a. an elongated sealing portion;
• b. an elongated U-shaped base portion lying parallel to and attached to the sealing portion, the U-shaped base portion intended for embracing engagement with and clamping retention on an edge flange, and embedded in said U-shaped base portion;
• c. a reinforcing and retention aiding core comprising:
• I. a plurality of separate and U-shaped resilient metal strips disposed transversely to the longitudinal axis of the base portion in closely and uniformly spaced relation therealong;
• the ends of the said strips being bent around and thereby securely attached to
• Ii. flexible continuous fibrous cords longitudinally disposed in each side wall of said U-shaped section and lying parallel to the longitudinal axis of said elastomeric body.

A dual density elongated elastomeric body, suitable for use as an automotive weatherstrip, comprising:

• a. an elongated low-density cellular elastomeric sealing portion;
• b. an elongated high-density elastomeric base portion lying parallel to and attached to the sealing portion, the base portion having a U-shaped section for embracing engagement with and clamping retention on an edge flange, and completely embedded in the U-shaped section;
• c. a reinforcing and retention aiding core comprising:
• I. a plurality of separate and U-shaped resilient metal strips disposed transversely to the longitudinal axis of the base portion in closely and uniformly spaced relation therealong;
• the ends of the said strips being bent around and thereby securely attached to
• Ii. flexible continuous cotton fiber cords longitudinally disposed in each side wall of said U-shaped section and lying parallel to the longitudinal axis of said elastomeric body.
