  • Patent number: 9676364
    Abstract: Airbag assemblies and vents are disclosed. An airbag assembly includes an airbag cushion and a vent assembly including a vent, one or more sheer tethers, and a peel tether. The sheer tether(s) are configured to be drawn to a taut state by expansion of the airbag cushion to configure the vent in a first venting state. The sheer tether(s) are releasably coupled to the peel tether. The releasable coupling is configured to maintain the sheer tether(s) releasably coupled to the peel tether. The peel tether is configured to transition from a slack state to a taut state as the airbag cushion continues to expand. The peel tether drawn taut produces a peel force transverse to the sheer force. The peel force causes the releasable coupling to release and the peel tether to uncouple from the sheer tether(s), to transition the vent to a second state.

  • Patent number: 9650012
    Abstract: An airbag of an airbag device for a driver's seat includes an exhaust strap which includes a cover section that closes off an outer opening of a vent hole at airbag deployment in an openable fashion and connecting bands extending from opposite sides of the cover section and joined to a driver-side wall. The exhaust strap is so configured, when the driver-side wall of the airbag cushions the driver at airbag deployment and moves toward a vehicle-side wall, that the connecting bands loosen and allow a region towards a distant edge of the cover section to loosen and pass through the outer opening such that the outer opening and an inner opening communicate to open the vent hole. The length of the distant edge of the exhaust strap is shorter than a length of a proximate edge of the exhaust strap.

  • Patent number: 9555763
    Abstract: A motor vehicle airbag module having an airbag consisting of an airbag fabric, and an inflation device The airbag having a ventilation area closed by a covering prior to inflation. A restraining strap has one end in the interior of the airbag detachably mounted on a fixed compartment and another end affixed on the covering. On inflation of the airbag before the release of the restraining strap, the strap holds the covering closing the ventilation area. The covering is a three-dimensional element which is connected via at least one partial area of its perimeter to the airbag fabric and that it can be folded such that, on release of the restraining strap, the three-dimensional element is unfolded due to the effect of the gas flowing from the ventilation area into the covering The covering is held in position in a detachable overlap with a part of the airbag.

  • Patent number: 9499119
    Abstract: In a driver seat airbag apparatus, an airbag includes a belt member and a vent mechanism. The belt member includes two connecting sections extending from opposite sides of a cover portion for covering a vent hole. The vent mechanism includes an outer panel that has a vent hole and is located outside of the cover portion, an inner panel that has an inner opening and is located on an inner side of the cover portion, and a guide. The connecting sections run through the guide and move toward the vent hole for letting the cover portion open the vent hole. The guide holds the connecting sections such that the connecting sections serve as the tethers. A joint of the tethers to the driver side wall is located toward a center of the driver side wall relative to the vent hole as viewed from a side of the driver side wall.

  • Patent number: 9333939
    Abstract: Provided are an airbag, an airbag unit, and a vent hole open/close control method that facilitate control of opening and closing of a vent hole, and suppress an increase in weight and cost of the airbag unit vent hole. The airbag 1 includes a vent hole 4, an open/close device 5 configured to open and close the vent hole 4, and a stretch tether 6 stretchable in stages and connected to the open/close device 5 and an airbag component. The stretch tether 6 assumes, depending on an expansion and unfolding status of the airbag 1, a first stage including transition from a slack state to a tense state, a second stage including stretching to a predetermined length while maintaining the tense state, and a third stage including being slackened when the driver contacts the airbag 1. The open/close device 5 maintains the vent hole 4 in the open state in the first stage, maintains the vent hole 4 in the closed state in the second stage, and shifts the vent hole 4 to the open state in the third stage.
