A seal construction including a metallic channel having a base, spaced side walls extending from the base in the same direction, and arms spaced from the base on the side walls and having ends directed toward, but spaced, from each other. A resilient strip is removably captured in the channel and extends therefrom for engagement with an element to be sealed. The channel base may be welded to a metallic element prior to insertion of the resilient strip to obviate the need for aligned openings for securing means such as screws, bolts, or the like and/or bonding agents of dubious reliability in varying environments.

Seal construction for vehicles

An environmental seal for use with a multidirectional control lever. The seal defines a movable structure including a first closure portion movable with the movable member and a second closure portion cooperating with the first closure portion to effectively maintain an opening through which the movable member extends sealingly closed in all positions of the movable member. The seal includes only two slidable closure elements for effectively sealing the opening in all positions of the movable member. Spring biasing structure may be provided for biasing the closure elements into movable sealed engagement.
