Abstract
Abstract A pressure-sensitive weatherseal is formed of a length of resilient material having a cross-section including a pair of legs at about a right angle to each other with the free ends of the legs being curved back on themselves and having arms extending outward from the curvatures at acute angles to the adjoining legs. The arms are flexibly disposed for repeatedly moving toward and away from the adjoining legs to act as a pressure-sensitive weatherseal.
