Abstract
A twin airbag with left and right airbag sections joined together. Each of the left and right airbag sections has at least one vent hole in a panel opposite to a corresponding inner facing panel. The vent holes are disposed at positions at which they align with each other when the airbag sections are flattened. Portions of the inner facing panels of the airbag sections may be stitched together through the vent holes.
Claims11
An airbag that is configured to inflate in a direction in which a distal end of the airbag moves away from a base end of the airbag, the airbag comprising:
- a left airbag section that is configured to inflate toward the left front of an occupant;
- and
- a right airbag section that is configured to inflate toward the right front of the occupant,
- wherein the left and right airbag sections are connected at the base end of the airbag along inner sides of the airbag sections,
- wherein the left and right airbag sections are configured to be inflated by a common inflator,
- wherein each of the left and right airbag sections is provided with at least one vent hole on an outer side, which is opposite to the inner side of the respective airbag section,
- wherein, when the left and right airbag sections are uninflated and are flattened such that the inner sides are adjacent the associated outer sides:
- (a) the vent holes align with each other, and
- (b) the inner sides of each of the left and right airbag sections opposite the associated vent holes are stitched together such that midpoints of the inner sides of the left and right airbag sections are joined.
An airbag system comprising:
- an inflator;
- and
- an airbag that is configured to inflate in a direction in which a distal end of the airbag moves away from a base end of the airbag, the airbag comprising:
- a left airbag section that is configured to inflate toward the left front of an occupant;
- and
- a right airbag section that is configured to inflate toward the right front of the occupant,
- wherein the left and right airbag sections are connected at the base end of the airbag along inner sides of the airbag sections,
- wherein the left and right airbag sections are configured to be inflated by the inflator,
- wherein each of the left and right airbag sections is provided with at least one vent hole on an outer side, which is opposite to the inner side of the respective airbag section,
- wherein, when the left and right airbag sections are uninflated and are flattened such that the inner sides are adjacent the associated outer sides:
- (a) the vent holes align with each other, and
- (b) the inner sides of each of the left and right airbag sections opposite the associated vent holes are stitched together such that midpoints of the inner sides of the left and right airbag sections are joined.
An airbag for protecting an occupant of a vehicle comprising:
- left and right airbag sections separated by a gap and integrally connected at a base of the airbag adjacent an inflator opening so that both the left and right sections receive inflation gas through the opening,
- wherein each of the left and right airbag sections includes a vent opening located on an outer side of each section facing away from the other section;
- wherein, when the left and right airbag sections are uninflated and inner sides of the left and right airbag sections are adjacent the associated outer sides:
- (a) the vent holes align with each other, and
- (b) the inner sides of each of the left and right airbag sections opposite the associated vent holes are stitched together, and
- wherein inner sides of each of the left and right airbag sections are connected together.
