Abstract

A sealing or guiding assembly for sealing or guiding the corner of a movable window glass, such as for the window in a motor vehicle door, comprises two lengths of sealing or guiding strips connected together at a corner. The corner is bridged across by a flexible flap which is produced by an in-situ moulding operation. The moulding operation is carried out so that the flap is connected to each sealing strip only over a small area. The flap is therefore otherwise spaced from each sealing strip by a gap which, during the moulding operation, is occupied by a plate defining part of the mould cavity. This plate and the gap protect an adjacent flocked area of a lip from damage by the heat of the moulding operation. The flap defines a shallow groove or ridge matching a ridge or groove either on the sealing strip or on a rigid support to which the strip and flap are to be attached. The groove-ridge pair engage each other when the two lengths of sealing strip and the flap are together placed into position on the rigid support, so that the areas of the flap which overlap each sealing strip to move into contact with the sealing strip and are held in such contact by the rigid support.
