ABSTRACT:
A flexible blade seal for a window assembly has an elongate body of substantially uniform cross-section formed of flexible elastomeric material. As viewed in cross-section, the blade seal has a seal segment forming an exposed, substantially planar sealing surface for contact with a surface of a windowpane, e.g., a sliding pane of the window assembly. In its free state the sealing surface is presented at an angle to the surface of the sliding pane, extending from a free end to a substantially flat end wall. A lateral segment of the blade seal extends from the end wall at an acute angle to the seal segment to an angled junction with a base segment. The base segment extends to a free distal portion adapted for attachment to the window assembly for mounting the blade seal. The flat end wall of the blade seal is generally perpendicular to the plane of the window opening and provides an abutting surface for surface-to-surface contact with another blade seal or other sealing member.
