  • Patent number: 8342567
    Abstract: In an airbag-equipped steering wheel, a plurality of horn switch mechanisms assembled to a bag holder each have a securing pin, which is inserted into a corresponding one of through holes formed in a metal core. A clip is engaged with a locking groove of each securing pin, so that each horn switch mechanism is fastened to the metal core. The through holes include one or more normal through holes that restrict inclination of the corresponding securing pins, and a special through hole that has an inclination permitting portion. The inclination permitting portion permits the corresponding securing pin to be inclined about the corresponding clip 13 serving as a fulcrum. In the special through hole, the securing pin is permitted to be inclined about the clip serving as a fulcrum only when the clips are disengaged from the securing pin in all the normal through holes.

  • Publication number: 20100145199
    Abstract: A cancer detection system (100) comprising a light generator (34) and a probe (24) including first and second light guides (26, 27). The first guide propagates the examination light emitted from the light generator and irradiates tissue (20) with the light. The second guide propagates the light scattered by the tissue, and a spectrum detector (36) measures the spectrum of the scattered light. A decision device (40) determines if cancer exists in the tissue, based on the measured spectrum. A fiber optic plate (22) is provided between the probe and tissue, and a moving mechanism (16) relatively moves the first and second light guides with respect to the tissue. Immersion oil may be disposed between the second end face of the fiber optic plate and the end portions of the first and second light guides.

  • Patent number: 7614656
    Abstract: The airbag apparatus includes an airbag having a tether including an occupant side tether belt and a vehicle body side tether belt. An intermediate portion of the vehicle body side tether belt is held at the side of a housing of the airbag by a retaining mechanism. At full inflation of the airbag, the clearance between the side of the housing and the occupant side tether belt is reduced when the vehicle body side belt is retained by the retaining mechanism whereas the clearance is enlarged when the vehicle body side tether belt is released from the retaining mechanism. The occupant side tether belt and the vehicle body side tether belt are linked with each other so that a central area of a protection plane of an occupant side wall of the airbag in the former case is generally parallel to the central area in the latter.

  • Patent number: 7481449
    Abstract: An airbag of an airbag device for the driver's seat of the invention is stored in a way that a carbody-side wall part and a driver-side wall part are overlapped and spread flat, and the airbag is folded in three steps so that widths between opposing outer edge portions with a gas opening as the center are reduced. In the first step of the folding, the carbody-side wall part and the driver-side wall part are overlapped and spread flat, and then right and left edge portions are folded toward the carbody-side wall so that wound regions are provided. In the second step of the folding, areas by front and rear edge portions are folded toward the driver-side wall, so that two regions that have been folded each cover approximately half the gas opening. In the third step, areas by the right and left edge portions that have been folded in the second step are folded in such a manner as to be bent upward.

  • Patent number: 7481455
    Abstract: In an airbag system for a steering wheel according to the invention, an airbag is folded through a first step and a second step after the airbag is unfolded flatly with a driver side wall and a vehicle body side wall superposed each other. Before the first step, the airbag is folded through a preliminarily-folding step to fold back a front edge side region to the vehicle body side wall along a folded line in a transverse direction. In the preliminarily-folded airbag, the folded front edge side is arranged within a range of 20% of the inner diameter of the ring part in each of opposite directions in the front-rear direction from a reference point on the inner peripheral edge of the front part of the ring part.
