  • Patent number: 8550491
    Abstract: An airbag device for straddle type vehicles is provided with: an airbag module in which a holding box that stores an airbag functions as a case; and an airbag control unit that controls said airbag module. The airbag module is provided with the holding box that is disposed immediately in front of a rider's seat, a lid that closes the opening of the holding box, and a hinge that functions as a rotary fulcrum for the lid when the airbag inflates, and that is positioned on the rear side, with respect to the vehicle, of the lid. A linking mechanism for restricting the opening angle of the lid is provided between the lid and the holding box.

  • Patent number: 7172210
    Abstract: A cover for an air bag device that enables an emblem to be secured to the cover in an extremely simple manner. The cover (module cover) has a recess for receiving the emblem. An extension of the emblem is extended through a hole in the cover. A distal end of the extension is bent along a rear side of the cover. A rib is pressed and welded by a thermal or ultrasonic welding element to form a welding body. The welding body covers the distal end of the extension.

  • Patent number: 6574540
    Abstract: A vehicle collision damage reduction system is provided. The system works by detecting the relative speed between the vehicle and an object, such as another vehicle. A danger level is calculated based on parameters such as speed and distance to the object; the danger level could be at an “emergency level” or at some lower level. Based on the danger level, different corrective measures and the degree of the corrective measures can be adjusted to attempt to minimize occupant injury. For example, the airbag can be adjusted to better protect the occupant, a pre-tensioner can be activated at a certain level, and the inclination of a child restraint seat may be adjusted as well.
