Abstract: Door weatherstripping to be attached along a periphery of a door panel of a sash-less door has an extruded main portion of rubber and end portions joined to ends of the extruded main portion to cover front and rear upper corners of the door panel. Each of the end portions has an insert member of polypropylene and a cover member of thermoplastic olefin elastomer which is molded to cover the outer surface of the insert member.

Abstract: An automotive weather strip comprising a base material, a urethane layer and an adhesive composition formed between the base material and the urethane layer, wherein said base material comprises an ethylene/propylene rubber and said adhesive composition comprises components (A) to (E), the weight ratio of component (A) to component (B) being 60:40 to 40:60,(A) an epoxy group-containing acrylic elastomer,(B) an ethylene/.alpha.-olefin copolymer,(C) an organic peroxide,(D) at least one member selected from the group consisting of a primary amines and an imidazole compound, and(E) calcium oxide.The present invention can provide an automotive weather strip in which a base material containing the ethylene/propylene rubber has been strongly adhered to the urethane layer forming a surface layer, and which can be produced efficiently without requiring many production steps and also without using a hygienically undesirable solvent-containing adhesive.

Abstract: The invention is a weather strip having good water-repellency and a method for preparing a weather strip for an automobile or a building. The weather strip includes a flock portion on its sealing portion surface to which a hardened reactive silicone layer is coated. The reactive silicone layer is made of a base material, a catalyst and a solvent. The hardened reactive silicone layer may further include a coupling agent, an ultraviolet cut-off pigment or a fine powder. The weather strip is prepared by applying the reactive silicone layer to the flock portion of the weather strip and curing the reactive silicone at a temperature of 80.degree.-150.degree. C. for 1-20 minutes.

Abstract: A glass run of the invention includes a furrow part on which a window glass moves and slides. The furrows of the furrow part are inclined at a predetermined angle with respect to the sliding direction of the window glass. When dirt or dust is deposited in between the window glass and the furrow part, it enters the furrows of the furrow part. The slanted configuration of the furrows of the furrow part, in combination with the sliding force of the window glass, moves dust or dirt along the furrows to a position where the dirt does not rub against the end face of the window glass. The structure of the invention keeps the window glass from undesirably rubbing dust or dirt, thus preventing an increase in sliding resistance and undesirable noise.

Abstract: A wiper blade rubber of an elongated configuration comprising a base portion of large thickness, a swinging portion substantially of a trigonal cross section, a neck portion connecting the base portion and the swinging portion and a thin plate-like lip portion disposed at the top end of the swinging portion. The basic material constituting most part of the base portion, the neck portion, the swinging portion and the lip portion is formed with soft and flexible rubber mainly composed of vulcanized ethylene-propylene rubber, and at least the surface of the lip portion is disposed with a surface layer constituted with a blended rubber composed of acrylonitrile-butadiene rubber and polyvinyl chloride resin and surface layer has a chlorinated surface layer.

Abstract: A wiper blade comprising a thick base section consisting of a head to be inserted through a slit formed in a backing plate, a body to be extended below the backing plate and a connecting neck interconnecting the head and the body; a turning section having a substantially triangular cross section; a neck section interconnecting the base section and the turning section; and a lip section extended from the ridge of the turning section in the form of a thin strip for wiping the surface of a windshield, wherein at least the surface layer of at least either the connecting neck or the neck section is formed of an ozone-resistant rubber.

Abstract: A wiper blade capable of preventing a harsh metallic noise which is made by the direct impact of a metallic backing plate associated therewith on a blade holder. Rubber flanges are formed integrally with the body of the wiper blade so as to extend upward from the upper surface of the body. The flanges cover at least the longitudinal side edges of the metallic backing plate placed on the upper surface of the body so that the longitudinal side edges of the backing plate will not impact directly on the blade holder.

Abstract: A wiper blade rubber is disclosed. The wiper blade rubber comprises a matrix formed of rubber made preponderantly of EPDM and vulcanized with a peroxide and a lip part having the portions thereof for sliding contact with the outer surface of a wind shield formed of chlorinated diene type rubber. The lip part has the opposite lateral sides in the direction of thickness of the leading end thereof formed of diene type rubber containing a chlorinated layer on the surface thereof, with the matrix exposed to sight at the leading edge of the lip part between the opposite lateral sides of diene type rubber. The diene type rubber in each of the opposite lateral sides has the outer surface thereof chlorinated.

Abstract: A wiper blade rubber of a constant cross section, composed of at least two kinds of rubber ingredient and manufactured by multi-color extrusion molding. In a wiper blade rubber according to this invention, a lip portion thereof to be in sliding contact with the glass surface is formed of a lubricating rubber and a swing portion generally of a trigonal cross section is mostly formed of a flexible rubber. In another wiper blade rubber according to this invention, a central part at the bottom end of the lip portion is formed of a high frictional rubber and both side parts of the bottom end of the lip portion is formed of a lubricating rubber. In a further wiper blade rubber according to this invention, an engaging part of the base portion, in the form of grooves or ridges, for engagement with an elongate rigid body held by a yoke of a wiper, is formed of a lubricating rubber and the swing portion is mostly formed of a flexible rubber.
