Abstract
A weatherstrip seal comprises a carrier structure without reinforcement which has an attached weather-sealing structure extending therefrom. The carrier structure has two spaced-apart walls connected by a base forming an interposed channel which is partially filled with a foamed, hot-melt adhesive. The carrier structure is adapted to fit over an anchoring mounting flange, while the weather-sealing surface has a sealing surface that prevents the entry of the elements through joined components moveable relative to each other.
Claims9
In a profile including:
- a carrier structure having two opposing walls defining a channel therebetween and being connected by a base, said walls being adapted to grip a profile-mounting flange positioned in said channel, and
- a sealing structure having a sealing surface, said sealing structure extending from said carrier structure, and being attached thereto,
- the improvement,
- wherein said carrier is fabricated without embedded reinforcement and said channel comprises opposing first and second truncated cavities meeting at their narrowest points to form a juncture adapted to grip said profile-mounting flange, and wherein said first cavity lies adjacent to said base and contains a hot-melt adhesive for retaining said profile mounting flange therein.

In a sealing profile including:
- a carrier structure having two opposing walls defining a channel therebetween and being connected by a base, said walls being adapted to grip a profile-mounting flange positioned in said channel, and
- a sealing structure having a sealing surface, said sealing structure extending from said carrier structure and being attached thereto,
- the improvement,
- wherein said carrier structure has a Shore A hardness of from about 70-100, and is fabricated without metal or other reinforcement, and
- wherein said channel comprises opposing first and second truncated cavities meeting at their narrowest points to form a juncture adapted to grip said mounting flange, and wherein said first cavity lies adjacent said base and contains a hot-melt adhesive having a viscosity of about 10,000-20,000 centipoise at 350.degree. F. which contains entrapped nitrogen bubbles therein.
