  • Patent number: 11703647
    Abstract: An optical fiber securing structure includes: an optical fiber including a coating, and a coating-removed section in which a partial section of the coating is removed from the optical fiber; a reinforcement member including main surfaces and a groove formed from one of the main surfaces toward an inside of the reinforcement member, where the groove has a pair of side walls and a bottom wall; and a resin member that secures the coating-removed section to the pair of side walls and the bottom wall. A bottom part of the groove that includes the bottom wall has a widthwise cross-sectional shape where the bottom wall constitutes a trapezoidal shape such that a distance between the pair of side walls becomes greater in a direction away from the bottom wall.

  • Patent number: 9783088
    Abstract: A vehicle seat includes a pad configured to support a body of a seated occupant. The pad has a transverse air passage extending in a direction along a back surface of the pad and a plurality of longitudinal air passages each having one end connecting with the transverse air passage and the other end open to a front surface of the pad. The transverse air passage has a first transverse air passage connecting an air introduction hole from a fan or an air discharge hole to the fan and the longitudinal air passage directly with each other, and a second transverse air passage connecting the air introduction hole or the air discharge hole and the longitudinal air passage with each other via a resistant body having a resistance against an air flow.
