Abstract: A weatherseal has a backbone, which is curvilinear in cross section to define a flange engaging channel and a window receiving channel, wherein the backbone is free of structural metal. The backbone is sufficiently curvilinear to sufficiently distribute stress loading within the cross section to allow unsupported lengths of the weatherseal to operably retain, locate and direct the glass panel. The flange engaging channel can include an arcuate closed end.

Abstract: A method of forming a division bar assembly having a pocket for receiving a fixed pane, the pocket defined by a pocket closed end and a pair of projecting pocket legs, and a channel for slidably receiving a movable pane, the channel defined by the pocket closed end and a pair of channel legs, wherein at least one of the channel legs is connected to a pocket leg at a transition intermediate the pocket closed end and a free end of the pocket leg, with the at least one channel leg initially diverging from the remaining channel leg. The diverging channel leg is urged toward the remaining channel leg in a downstream post-forming step.

Abstract: A vehicular weatherseal includes a weatherseal body having a flange engaging channel, a panel contacting member and a lock strip for securing the channel relative to a flange of the vehicle. The lock strip performs at least one of a sealing function with a panel of the vehicle or a trim function and includes a gap closing lip extending generally laterally from the flange engaging channel. The panel contacting member extends from one of the projecting legs for contacting the vehicle panel at a location transverse to the flange engaging channel.

Abstract: A weatherseal has a portion of a sealing area defined by a freeze release material. The freeze release material has a lower affinity to bonding with water or ice than an adjacent area of the sealing area. The freeze release material is incorporated into the sealing portion to reduce the overall affinity of the weatherseal to ice bonding, while maintaining the desired performance characteristics of the seal including the flexibility and recovery of the sealing surface. The area of contact by the weatherseal is defined by both the freeze release material and a different material forming an adjacent portion of the weatherseal.
