With Confinement Deflation Means Patents (Class 280/739)
  • Patent number: 10773680
    Abstract: An oscillation reducing structure for a front passenger seat airbag includes a front passenger seat airbag equipped with a center bag and a friction imparting device. When inflated and deployed, the front passenger seat airbag contacts with a front windshield glass in a first area, and contacts with an instrument panel in a second area. The friction imparting device makes at least one of a coefficient of frictions of the first area and the second area greater than that of other areas of the front passenger seat airbag. The friction imparting device is formed such that a coefficient of friction thereof in a vehicle width direction is greater than in a vehicle front-rear direction.

  • Patent number: 10647287
    Abstract: An airbag includes an internal pressure adjusting mechanism, including: a tether arranged in a bag part; a long side part; and a short side part; and adjusting an exhaust of the inflation gas: to be in an exhaust mode in which the exhaust is facilitated when the tether is loosened; and to be in an exhaust suppression mode in which the exhaust is suppressed when the tether is stretched. In a state where the tether is loosened during the exhaust mode, facing edge parts of the long side part and the short side part are separable. In a state where the tether is stretched during the exhaust suppression mode, the facing edge part of the long side part and a root side part are inflated around the short side part and a leading edge side part contacts a back surface side of the short side part.

    Abstract: An airbag formed of an airbag fabric (10) having a slit-shaped adaptive ventilation opening (11) which in the folded-up state of the airbag is held in at least a partially closed state by an arrester strap (20) having an end overlapping the adaptive ventilation opening (11) and fastened to the airbag fabric (10). The arrester strap (20) is guided through a safety-loop opening (31). The safety-loop opening is formed by a reinforcing blank (13) enclosing the ventilation opening (11) and the opening (31) for the arrester strap (20) is formed by an edge area of the reinforcing blank (31) not connected to the airbag fabric (10), and in that the end of the arrester strap is connected with both the airbag fabric (10) and with the reinforcing blank (13) in an area lying opposite with respect the edge section of the ventilation opening (11) forming the opening (31).

  • Patent number: 9205799
    Abstract: An airbag and an airbag device are provided that can effectively prevent a rise of the internal pressure of the airbag when the airbag is hindered from being normally inflated/deployed while gas is prevented from being wasted. An airbag includes a pair of side panels that form a bag by being sewn together, an insertion hole formed in the side panel, and a valve disposed on an inner side of the side panel so as to stop up the insertion hole and having two end portions connected to the side panel. While the airbag is housed in the structure, the valve is drawn to an outer side of the side panel through the insertion hole and disposed so as to stop up the insertion hole and, while the airbag is inflated/deployed, the valve is drawn to the inner side of the side panel.

  • Patent number: 9187058
    Abstract: An airbag device includes: an airbag; an inflator; a gas discharge state switching member; and a tether belt which is one example of a connecting member. The gas discharge state switching member is switched over from a gas discharge state to a gas non-discharge state by being pulled into the inside of the airbag. The tether belt connects the gas discharge state switching member and a portion of an inner peripheral portion of the airbag to each other. An arranged position of the gas discharge state switching member, a position where the tether belt is connected to the inner peripheral portion of the airbag, and a passing line of the tether belt are disposed at portions which avoid a portion of the airbag which comes into contact with an occupant in a regular posture state when the airbag receives the occupant.

  • Patent number: 9150189
    Abstract: Airbag assemblies and active vents for airbag assemblies are disclosed. An airbag assembly may include an airbag cushion, an active vent having an aperture and a patch configured to plug the aperture, a depth-delimiting tether, a cross tether, and a control tether. The control tether may be coupled to the patch and the depth-delimiting tether. The depth-delimiting tether and the control tether may be drawn taut as the airbag cushion expands during deployment to draw the patch toward the aperture from a first position that allows unobstructed venting to a second position that obstructs venting through the aperture. The depth-delimiting tether and the control tether can be in or transition to a slack state due to occupant impact with the airbag cushion. These tethers may also be in a slack state during the early stage of deployment.

  • Patent number: 9108590
    Abstract: Airbag assemblies and active vents for airbag assemblies are disclosed. An airbag assembly can include an airbag cushion that defines an inflatable chamber and an active vent that comprises an aperture and a patch configured to plug the aperture. A first control tether is coupled to the patch and coupled to the airbag cushion. The first control tether is drawn taut as the cushion expands during deployment to draw the patch toward the aperture from a first position that allows unobstructed venting through the aperture to a second position that obstructs venting through the aperture. The first control tether, or a second control tether, is configured to be drawn taut to close the active vent. Responsive to impact with the airbag cushion, a control tether is configured to slacken to open the active vent.

  • Patent number: 9022423
    Abstract: An airbag device for stably controlling gas discharge and restraining an occupant in a vehicle. A first vent hole, for discharging gas from the airbag, is formed in a portion of the airbag, and one end of a tubular discharge restricting member is connected to the first vent hole. Once the airbag is inflated and deployed to a predetermined extent or more, the first vent hole is closed by the discharge restricting member. Prior to deployment, at least a portion of the airbag is folded in a bellows shape to form a folded portion. The connecting portion between the discharge restricting member and the first vent hole is positioned in a trough portion of the folded portion. The other end of the discharge restricting member is stored so as to face the outer side and not to protrude beyond an outer edge of the folded portion.

  • Patent number: 9004531
    Abstract: The present invention incorporates a tether release system within a conventional airbag system or a conventional vehicle occupant protection system. Release of an associated tether may simultaneously open a vent on an associated airbag. A housing contains an actuator contained within the housing for actuation of the tether release system upon receipt of a crash detection signal, for example. A first moving member is configured for receipt of a propulsive force emanating from the actuator upon actuation of the tether release system. A movable tether release member is contained within the housing wherein the movable tether release member operably communicates with the first moving member upon actuation of the tether release system, for release of an associated tether.
