## Abstract

A window sealing system for double pane moveable automotive windows includes a seal having bulbous portions for compressively engaging peripheral edges of each glass pane and sealing lips for engaging non-peripheral surfaces of the panes.

## Claims

### Claim 1

A window sealing system for an automobile door of the type formed of inner and outer door panels spaced by a U-channel and having a window aperture formed through the panels adjacent the open end of the U-channel and a window pane assembly having inner and outer spaced, substantially parallel window panes defining an outer peripheral channel therebetween and being slidably movable interiorly of the door panels from one side of the window aperture between a closed position and an open position with respect to the window aperture, the system comprising a seal member carried on the other sides of the window aperture and having lip seal portions sealingly engageable against inner and outer non-peripheral faces of the inner of the window panes and a pair of bulb portions compressively sealingly engageable against outer peripheral edges of each of the window panes, one of the bulb portions being carried in the U-channel.

### Claim 2

A window sealing system for an automobile door of the type formed of inner and outer door panels and having a window aperture formed through the panels and a window pane assembly having inner and outer spaced, substantially parallel window panes defining an outer peripheral channel therebetween and being slidably movable interiorly of the door panels from one side of the window aperture between a closed position and on open position with respect to the window aperture, the system comprising a seal member carried on the other side of the window aperture and sealingly engaging the window pane assembly within the outer peripheral channel and having lip seal portions sealingly engageable against inner and outer nonperipheral faces of the inner of the window panes, other seal member lip seal portions sealingly engageable against inner and outer nonperipheral surfaces of the outer of the window panes, and a pair of bulb portions compressively sealingly engageable against outer peripheral edges of each of the window panes, and wherein a U-shaped member is jointed to the inner and outer door panels to define a channel therebetween and one of the bulb portions is positioned in the channel to sealingly receiver outer peripheral edges of the inner of the window panes.
