A seal for a motor vehicle is extruded from polymeric material and has a retention part (25) and a sealing portion (43) for forming a seal with a part of the vehicle at two spaced locations (39, 41), there being an inverted generally T-shaped stiffening carrier (27) having at least a part thereof located in the sealing portion (43) to control the collapse characteristics of the sealing portion (43). It is preferred that the sealing portion (43) has two spaced bulbous portions spaced apart by a valley which, in use, forms a sound insulating air bubble, but the sealing portion may be formed of two inclined spaced sealing ribs into which respective limbs of a modified carrier partly extend. The carrier is shaped to fit within the seal, but could have other uses, and may be made of metal or polymeric material, have different cross-sectional shapes, and be slotted, hinged, or of a combination of different materials, hardness, thickness or the like, to affect its characteristics. |
