  • Patent number: 9067563
    Abstract: In a head protection airbag apparatus, an airbag includes an airbag body and a tension cloth. The airbag body has an end side inflation portion which is arranged in an end portion on the tension cloth side. The end side inflation portion is divided from other general inflation sections in the airbag body by a division portion. The tension cloth is in an arranged state so as to cover an inner vehicle side of the end side inflation portion, allows the base portion side to be joined to an front edge side of the end side inflation portion, is inserted into a slit formed in the division portion while being inverted so as to cover an outer vehicle side of the end side inflation portion, and allows the leading end side to be fixed to the vehicle body side.

  • Publication number: 20150158450
    Abstract: A head protection airbag apparatus includes an airbag which is configured so that an attaching portion arranged on an upper edge thereof upon completion of inflation is attached to a body of the vehicle using an attaching clip. The attaching portion includes an attaching hole to which the attaching clip is insertable. The attaching clip includes an attaching leg. The attaching leg includes an insertion shaft portion adapted to be inserted in the locking hole and at least a pair of locking claws. The attaching hole is configured so that, when the attaching leg is inserted through the attaching hole, an peripheral edge portion of the attaching hole is pressed against an outer peripheral surface side on a region of the insertion shaft portion which is located more toward the base portion than the locking claws.

  • Publication number: 20140239620
    Abstract: In a head-protecting airbag device, an airbag includes an inflatable curtain portion that is deployable over an inboard side of a window and an overlap inflatable portion that overlaps with an inboard side of the inflatable curtain portion at airbag deployment. The overlap inflatable portion is so configured as to complete inflation after the inflatable curtain portion has completed inflation. The overlap inflatable portion is deployable into a generally rod shape extending at a slant relative to an up and down direction and a first end of the overlap inflatable portion communicates with the inflatable curtain portion at a vicinity of an upper edge of the inflatable curtain portion as inflated whereas a second end of the overlap inflatable portion is jointed to a lower edge of the inflatable curtain portion away from the first end in an up and down direction.

  • Publication number: 20140197593
    Abstract: Disclosed are a sheet feeding apparatus and an image forming apparatus capable of reliably separating and feeding sheets one by one without delay and damage to a sheet for a high speed of a printer or the like. A sheet feeding portion has a nip guide member having a sloped guide surface sloped so as to guide a leading end of a sheet to a separation nip portion such that a guide leading-end is biased to a feed roller with a predetermined distance from the feed roller. A support member supports the nip guide member not to recede from the feed roller when a thickness of a sheet bundle bumping into the sloped guide surface is smaller than a predetermined distance between the feed roller and the guide leading-end and supports the nip guide member to recede from the feed roller when the thickness is larger than the predetermined distance.

  • Patent number: 8727376
    Abstract: An airbag includes an airbag body and an inner tube. The inner tube includes a gas upstream section located in an upstream region of an inflation gas stream fed from a gas generator and a gas outlet section that opens toward an inflatable region of the airbag body and feeds an inflation gas to the inflatable region. The gas outlet section includes a check valve section. The check valve section has a flexible and a generally tubular shape extending and opening toward the inflatable region due to pressure of an inflation gas so as to stream the inflation gas into the inflatable region. After the gas generator has finished discharging the inflation gas, the check valve section folds back toward the gas upstream section due to an internal pressure of the inflatable region and closes off the gas outlet section.
