<p>A waist seal, such as for sealing against a window glass (6) movable up and down through the waist gap of a vehicle door, comprises a channel-shaped gripping portion (16) supporting the waist seal on door panels (10, 12). The gripping portion (16) carries lips (28, 30) making sealing contact with the window glass (6) as it slides up and down. Each lip (28, 30) may be made of relatively hard material. Each lip (28, 30) is mounted on the outside of a respective wall (24, 26) of a respective hollow chamber (20, 22) formed within the material (17) of the gripping portion (16). The walls (24, 26) and the chambers (20, 22) damp vibration of the lips and thus prevent or minimise an unwelcome noise or squeak as the window glass (6) is raised or lowered. Each of these hollow chambers (20, 22) may be filled with a damping material such as a polyisobutylene material.</p> |
