<p>A seal for sealing against a window glass 6 movable up and down through the waist gap of a vehicle door, comprises a reinforced channel-shaped gripping portion 16 supporting the seal on door panels 10,12. The gripping portion 16 carries lips 28,30, which may be made of relatively hard material, making sealing contact with the planar surface of the window glass 6 as it slides up and down. Each lip 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 unwelcome noise as the window glass 6 is raised or lowered. Each of the hollow chambers 20,22 may be filled with a damping material such as a polyisobutylene material. In an alternative embodiment (figure 3), the two lips may be joined (28,38) to form a single hollow sealing portion.</p> |
