  • Patent number: 6647666
    Abstract: A door weather strip, which is of annular form as a whole, includes a base section and a hollow sealing section as its basic constituent elements. The portion of the door weather strip corresponding to the corner part of the upper portion on the center pillar side of the front door provides a molded section, and any other section provides a continuously formed extrusion section. On the portion other than the lower side portion in the peripheral portion of the opening section for the front door of a vehicle body, the ridge portion as along the peripheral portion thereof is provided. In the closed state of the front door, the sealing section is elastically deformed so as to be pressed and extended in opposite directions away from the top portion of the ridge portion.

  • Publication number: 20030209890
    Abstract: An interior finish member having a door suitable for an air bag comprises a main body and a cover portion. The main body surrounds the periphery of the cover portion, and the main body and the cover portion form a continuous surface. The cover portion covers a folded air bag of an air bag device. The cover portion comprises: a door portion which covers the folded air bag; a breakable portion defined by a recessed periphery of the door portion whose thickness is thinner than adjacent portions of the interior finish member so that it may be broken easily in deployment of the air bag; and a hinge portion for connecting the door portion with the main body and for providing a pivot around which the door portion rotates when the door portion opens under a force of an expanding air bag. The main body is made of thermoplastic resin, and the cover portion is made of thermoplastic elastomer. Because they are capable of thermally fusing with each other, the main body and the cover portion can be integrally formed.

  • Publication number: 20010008058
    Abstract: A front door weather strip is annular as a whole, and has one mold molding section fixed to the corner section which is the rear side upper section of a door frame, and one extrusion molding section. The extrusion molding section includes a base section and a hollow sealing section. A seal lip is integral with the part of the extrusion molding section which corresponds to the upper section of the door frame. The length of the seal lip is gradually changed at a front upper corner part. During extrusion molding, the part of the extrusion molding section which corresponds to a front lower corner part is formed as follows: That is, the sealing section is larger in height than the other part. At least the part of the extrusion molding section which corresponds to the lower section is smaller in wall thickness of the vehicle outside base end part of the sealing section than the part which corresponds to the upper section.

  • Patent number: 5427408
    Abstract: A process is provided for molding a pad for an air bag device. The pad has a cover portion, a hinge portion disposed near one edge thereof, and a bracket portion extending from the hinge portion at an angle with respect to the cover portion. The pad is provided with a flexible reinforcing insert embedded therein, extending from the bracket portion to the cover portion through the hinge portion. The insert is set in a mold, while the mold is open, so that the insert may be held in position by pins projecting from the mold into that portion of a mold cavity which forms the bracket portion of the pad. After the mold is closed, a molding material is injected into the mold cavity through a gate connected to that edge of the cavity which forms the one edge of the cover portion of the pad. A pad formed by the process is also provided.

  • Patent number: 5269837
    Abstract: An evaporation loss control device provided with a polymer chamber filled with polymer absorbent, a charcoal chamber filled with charcoal, introduction and purging pipes for connecting the polymer chamber with a fuel tank and an engine intake passage, respectively, an air pipe for ventilation connected to the charcoal chamber, and a vapor passage, which has various forms. For example, the vapor passage may be formed in spiral to encircle the polymer chamber, or provided between the polymer and charcoal chambers, thus allowing the evaporated fuel to pass therethrough. The vapor passage is constructed to prevent the evaporated fuel trapped by the polymer absorbent from flowing into the charcoal chamber, and also to prevent the liquid fuel from being absorbed by the charcoal.
