The automobile weather strip is characterized in that: the trim part has an insert member and a covering material for covering the insert member; the covering member is provided with holding lips for holding a flange part on an inner surface of the trim part; a sponge material of a rubber formed by using a blend material of an EPDM rubber and an olefin-based thermoplastic synthetic resin and a sponge material of a rubber having physical properties of a specific gravity of 0.6 to 0.8 and a 25%-stretching stress of 500 KPa or more are used as the covering material.

Automobile weather strip

A weather strip is mounted on a circumferential portion of a door opening for a vehicle door. The weather strip includes a trim portion having a substantially U-shaped cross section and a hollow seal portion, and a designed lip is formed on the trim portion so as to extend therefrom. An adhesive layer and a flocked portion are formed on a designed surface of the weather strip such as an external surface of the designed lip, the flocked portion being provided with a multiplicity of pile fibers which are bonded to the adhesive layer at one end thereof, which pile fibers are each angled randomly with respect to a normal direction to the external surface of the lip portion.

Weather strip and manufacturing method thereof

A weather strip has a trim portion and a seal portion. The trim portion has a vehicle interior side wall, a vehicle exterior side wall, and a connecting portion. A metal insert is embedded in the trim portion. The insert has piece portions and a center bond portion which connects the piece portions to one another. The thickness of each of parts of the insert, which are other than both curved parts, is set to be thinner than the thickness of each of both the curved parts. Thus, the thickness of the insert, except for the curved parts, is small. Consequently, the entire insert, thus, the entire weather strip can be lightened. On the other hand, both the curved parts are relatively thick. Accordingly, the weather strip can assure predetermined strength and stiffness and can easily maintain an initial shape.

A weather strip is mounted at the peripheral part of a door opening of a door for an automobile. The weather strip includes a sectionally nearly U-shaped trim part and a hollow seal part. A design lip is extended out from the trim part. A decoration layer of a non-woven fabric is formed on the design surface of the weather strip such as the outer surface of the design lip through a resin bonding layer of polyethylene (PE). The non-woven fabric constituting the decoration layer contains fibers subjected to 'crimping processing' and has predetermined elasticity (stretch of 5 mm or more when load of 20 N is applied).

A vehicle door includes a glass run which corresponds to an outer peripheral configuration of a door glass. The glass run includes a body portion which is provided with a bottom wall portion and an interior side wall portion and an exterior side wall portion which extend from both edges of the bottom wall portion, respectively, and a pair or seal lips which establish seals between the door glass and themselves. Furthermore, with respect to a direction towards an inside or outside of a door frame, a foot portion of the exterior seal lip is positioned further on the outer peripheral side than an inner-peripheral edge portion of a molding member.

Glass run mounting structure

An extruded product formed by extrusion molding and continuing in a longitudinal direction includes: an extruded product body; and a decoration layer provided integrally on a surface of the extruded product body, wherein the decoration layer is provided on a substantially entire surface of the decoration layer by combining an irregular surface pattern and a plurality of linear grooves on the surface thereof, and the depth of the linear groove is deeper than the depth of the irregular surface pattern.

Extruded product

An opening trim weather strip includes a trim portion, a seal portion, and a cover lip integrally formed to the trim portion and extended to a vehicle interior side thereof. The cover lip is formed with a cover lip main body by a sponge member and formed with a cover lip skin layer formed by a solid member at a surface of the cover lip main body. A modulus of the cover lip skin layer is made to be equal to or smaller than a modulus of the cover lip main body.

Opening trim weather strip

An automobile door has a glass run corresponding to a glass door. The glass run includes a body portion, which has a bottom wall portion, and a vehicle interior side wall portion and a vehicle exterior side wall portion respectively extending from opposite ends of the bottom wall portion, and also includes a pair of seal lips which performs sealing between the door glass and the glass run. Furthermore, in a cross-sectionally substantially-U-shaped outer peripheral portion of the body portion, sponge rubber layers are provided in a predetermined range in a longitudinal direction of a cross-section of the vehicle interior side surface wall portion and a predetermined zone including a continuously connecting portion between the bottom wall portion and the inner outer side surface wall portion, respectively. An auxiliary lip is provided at a continuously connecting portion between the bottom wall portion and the vehicle interior side wall portion. Additionally, a sponge rubber layer is formed on a door glass facing surface of the bottom wall portion.

An automobile trim has a trim body (a base layer) formed of a rubber composition and having a design surface, a decorating layer formed of a thermoplastic elastomer composition and thermally bonded integrally with the design surface of the trim body. A thermal bonding layer is formed of a thermoplastic resin composition and interposed between the decorating layer and the trim body so that the decorating layer is thermally bonded integrally with the trim body through the thermal bonding layer. The thermal bonding layer has a thickness to an extent not to prevent bending flexibility when the trim is attached to a vehicle body. In another example, a cushion layer is laminated on the trim body and formed of sponge rubber of EPDM, a decorating layer is laminated on the cushion layer and formed by foaming olefin thermoplastic elastomer, and an olefin bonding layer for bonding the cushion layer and the decorating layer.

Method for manufacturing automobile weather strip

A glass run has extruded portions and molded portions. The extruded portions and the molded portions are made of TPO. The glass run is attached to sashes DS. Insert members made of PP are embedded respectively in a base portion of the glass run correspondingly to a long side portion and an upper side portion of each of the molded portions. When the glass run is attached, protrusions of the insert members protruding from the base portion can engage with or stand close to edge portions of the sashes so that the protrusions can be locked with the sashes. Since the protrusions are harder than the molded portions under a relatively high temperature atmosphere, the protrusions are hardly deformed or broken even when stress caused by opening and closing of a glass is applied repeatedly to the protrusions.

A glass run for use in a motor vehicle, which is capable of preventing seal lips from closely contacting inner surface of side walls thereof, and accordingly preventing the generation of noise therein. An opening-side groove is formed in an inner surface of an outside wall near an open end thereof to define a space between the inner surface of the outside wall and a base of the outside seal lip when an end of an outside seal lip contacts the inner surface of the outside wall. And a bottom-side groove is formed in the inner surface of the outside wall so as to receive the end of the outside seal lip which is pushed by the door glass. A protruding part having a rib is further formed in the inner surface of the outside wall so as to contact the widthwise middle of the outside seal lip which is pushed by the door glass.

Glass run for motor vehicle

A vehicle glass run is formed with a horizontal-side extrusion part, vertical-side extrusion parts, and corner molding parts for connecting the terminal ends of those in an L shape by molding. The horizontal-side extrusion part and the vertical-side extrusion parts are made of a first material of an olefin thermoplastic elastomer. The corner molding parts are made of a second material which is an olefin thermoplastic elastomer and has a melt flow rate lower than that of the first material. The material swiftly reaches the terminal ends of the extrusion parts, and heat welds them together.
