  • Patent number: 9421936
    Abstract: A light-weight and inexpensively-manufacturable case member of an airbag device is provided. The case member includes an inner portion integrally formed with an edge portion of an opening portion of a housing portion configured to internally hold a folded airbag and an inflator. A lid is fixed to a housing portion at a position where the lid at least partially covers the airbag housed in the housing portion. The opening portion is covered by an outer portion. Thus, a light-weight case member in which the inflator and the folded airbag are housed in the housing portion and covered by the lid can be manufactured inexpensively, without integration of a separately provided housing portion and lid or fixing the airbag or the inflator using an additional component.

  • Patent number: 9378863
    Abstract: An insulating varnish forms an insulating coating film having a shape that corresponds to the shape of an opening of a die, having a uniform thickness. The insulating varnish is applied onto a surface of a conductor, subsequently passes through a die to remove the excess applied insulating varnish, and is then dried or baked to form an insulating coating film on the surface of the conductor. The insulating varnish has a viscosity of 10 Pa·s or more measured by a B-type viscometer at 30° C. The insulating varnish preferably contains no filler, and is preferably a polyimide precursor solution. Since the insulating varnish has a high viscosity, baking and solidification can be performed while maintaining a shape formed when the insulating varnish passes through a die.

  • Patent number: 9079559
    Abstract: An airbag includes a vent hole discharging gas, a slide tether performing transition of a state of the vent hole, from an open state via a close state to the open state, by changing between a slackened state and an extended state, and a slide tether cover guiding the slide tether. The other end portion in a longitudinal direction of the slide tether body portion constitutes a first supporting point by being fastened in a direction going from the vent hole toward a mounting position of the inflator, bifurcated portions constitutes a second supporting point by the other end portion of the slide tether cover being fastened, terminal end portions of leg piece portions constitute a third supporting point by being respectively fastened. When the airbag is deployed, transition of a state of the vent hole is performed.
