The body includes a mounting baseplate, a extending plate, and a distended part. The extending plate extends from an end of the mounting baseplate to outside in a widthwise direction of the vehicle. The distended part is distended to an inner angle part of a corner between the mounting baseplate and the extending plate and has a hollow part. The seal part is comprised of a basal part formed on a vehicle-interior-facing surface of the mounting baseplate and a seal-lip part formed on the basal part. The basal part is set apart toward another end of the mounting baseplate relative to the hollow part. | 05-19-2011 |
| 20100239826 | METHOD OF MANUFACTURING CORE, METHOD OF MANUFACTURING TRIM, AND CORE MANUFACTURED BY THE SAME - A method of manufacturing an elongated core which is buried in an elongated trim. The method includes, forming slits to a metal plate, which extend in a second direction, at predetermined intervals in a first direction so as to form core pieces between the adjacent slits; and rolling a portion of the metal plate in which the slits are not formed in the second direction to form a rolled portion extending in the first direction, and expanding the slits in the first direction to form spaces, thereby preparing a primary core in which the core pieces and the spaces are alternately provided in the first direction. Additionally, the method includes, supplying the primary core to between a pair of deformed portion forming rollers engaged with each other such that reinforcing defaulted portions extending in the second direction are repetitively formed in the first direction. | 09-23-2010 |
| 20100199568 | GLASS RUN CHANNEL ASSEMBLY AND ITS MANUFACTURING METHOD - A glass run channel assembly which is made of an elastic polymeric material and which is capable of being mounted to a vehicle, including: a first long glass run channel, a second long glass run channel and a connecting glass run channel which connects the first and second glass run channels, the connecting glass run channel comprising a base bottom portion. The base bottom portion is provided with a projection portion which projects from an outer circumferential side surface of the base bottom portion. The projection portion includes at least a portion of a reinforcing member. The reinforcing member is molded in advance from a material which is harder and more rigid than the elastic polymeric material of the connecting glass run channel, and the reinforcing member includes a base portion arranged at the base bottom portion and a trunk portion which projects towards an outer circumferential side. | 08-12-2010 |
| 20100192470 | WEATHER STRIP, AND ATTACHMENT STRUCTURE OF WEATHER STRIP - A weather strip is provided. The weather strip is arranged so as to intersect a portion joined by overlapping a plurality of panels, and is provided with a tip projection portion which projects onto an extension line of the exterior side wall portion from the tip of an exterior side wall portion of an attachment portion. The tip projection portion is formed from a material which deforms easier than a material forming the sealing portion and is formed in a shape which becomes thin towards a projecting direction with a width dimension which does not exceed the thickness of the tip of the exterior side wall portion in a cross section along the width direction of the attachment portion, and when the attachment portion is attached to the flange, the tip projection portion stretches in the longitudinal direction of the attachment portion and comes into contact with the panels. | 08-05-2010 |
| 20100086732 | TRIM AND CORE THEREOF, AND METHOD AND APPARATUS FOR MANUFACTURING TRIM AND CORE - The occurrence of recessed marks on a surface of weatherstrip having a core embedded therein is prevented. Core ( | 04-08-2010 |
| 20090278379 | Glass Run Channel Assembly - A glass run channel assembly is provided. In the glass run channel assembly, after being mounted, an elastic force is generated in a vertical side portion which contacts a vertical frame of a door frame, and an elastic force is generated in an upper side portion which contacts an upper frame of the door frame. Here, the cross-sectional shapes of the upper side portion and the vertical side portion are adjusted such that the frictional force per unit length obtained by multiplying a coefficient of static friction of the upper side portion with the upper frame by the elastic force is larger than a frictional force per unit length obtained by multiplying the coefficient of static friction of the vertical side portion with the vertical frame by the elastic force. | 11-12-2009 |
| 20090133335 | BELT MOLDING FOR VEHICLES - A vehicle belt molding includes an attaching member and a seal lip. An elastic repulsive member is disposed between the engage wall portion and the seal lip and integrally provided with a fixed piece portion, a shifting piece portion, and a connecting piece portion. The seal lip is always urged toward the window pane by an elastic restoring force of the connecting piece portion itself or by a cooperative function of the elastic restoring force and an elastic restoring force of the elastic polymer material. When the attaching member is mounted to the mounting member, the seal lip causes the contacting portion to be elastically restored by the elastic restoring force toward a thickness direction of the window pane at a speed exceeding a restoring speed obtained only by the elastic polymer material. | 05-28-2009 |
| 20090071570 | Pour Connector and Pour Port Structure of Liquid Container - A guide piece having a guide surface is integrally formed in a body portion so as to protrude from an inner circumferential wall surface of a pour passage toward the center thereof. A gas guide portion is formed in a portion of the pour passage in which the guide piece is formed. The gas guide portion is defined by a lower surface of the guide piece and the inner circumferential wall surface of the pour passage. When the pour connector is connected to the pour port of the liquid container to use the same, a projection edge of the guide piece is positioned below its base portion on the inner circumferential wall surface of the pour passage in the gravitational direction, so that the liquid poured into the pour passage can flow toward the center while it is guided by the guide surface, whereas the gas guide portion is positioned above the projection edge of the guide piece in the gravitational direction, so that gases in the container can be discharged from circumferential ends of the gas guide portion in a direction opposite to the pour direction. | 03-19-2009 |
| 20080286395 | Molding manufacturing method and apparatus - A molding manufacturing method includes: preparing a molding body including a molding main body made of thermoplastic material and a decorative layer higher than the molding main body in hardness and melt temperature; setting the molding body in a fixed die; heating and softening an end portion of the molding body while maintaining the decorative layer softer than the molding main body, by irradiating an infrared ray onto a back surface of the molding main body corresponding to the end portion; and press forming the end portion of the molding body by applying a movable punch onto the fixed die while the end portion of the molding body is in a softened state to bend the end portion of the molding body to obtain an end cover portion having a predetermined shape. | 11-20-2008 |
