Abstract: A protective cover which is generally in the form of a flexible bellows construction secured at each end by collars in order to define an interior space includes vent means. Thus, when the cover is deformed, the volume within the interior is altered by aspiration or evacuation through the vent means. The vent means includes a vent element in order to allow air or fluid transfer into and out of the interior but prevent ingress of contaminants such as grit and water to the interior.

Abstract: A protective bellows formed by injection (blow) moulding has a large-diameter end with a fixing collar (28) for sealingly embracing an externally tri-lobed surface of a housing of an articulation joint for a motor vehicle transmission. The fixing collar (28) comprises a circumferential outer surface 29 and an inner surface (30). The inner surface (30) is made up of part-circumferentially curved surface portions (30A, 30B, 30C) for engaging the three lobes of the housing, and three equi-angularly spaced inwardly curved integral surface portions (32A, 32B, 32C) which are shaped to engage the spaces or grooves between the three lobes on the housing. The resilient material between the outer surface (29) and each inwardly curved surface portion (32A, 32B, 32C) is formed with several slots (34) arranged with their depths directed in a radial direction. The slots (34) aid the de-moulding process.

Abstract: A fender (10) which is essentially U-shaped in cross section and which consists of elastomer material in its energy-absorbing part, is manufactured in planar configuration and folded to U-sectional shape on mounting. To make folding possible and to provide both an equalisation of tensile stresses and an increase of the transfer of forces between the web (12) and the legs (13) of the U-shaped cross section, longitudinal slots (17) are formed on the inside of the U-shaped cross section at the transition between the web and the legs. The mouth edges of the slot are bevelled and form mutually abutting supporting surfaces (18) for said transfer of forces. At the bottom of the slot (19), a longitudinal open channel (21) has been left to equalize the tensile stress occurring in the fender material on folding.
