ABSTRACT:
Sealing strips, such as for sealing around door openings in vehicle bodies, for example. The sealing strip comprises a hollow tubular soft sealing section which is supported around the door opening by means of a channel-shaped gripping section. In order to support the sealing section at positions around the opening where the sealing strip has to be curved or bent, lengths of soft flexible material of generally rectangular cross-section are positioned within the hollow interior of the sealing section at the appropriate positions. Each such length is a relatively loose fit within the hollow interior of the sealing section and is held in position by means of adhesive. The lengths of the soft flexible material prevent partial "collapse" or distortion of the sealing section at the bends or curves, but because they do not fill the hollow interior of the sealing section, they do not impair its compressibility in the sealing direction.
