20080243343 | Control Method for Occupant Restraint Apparatus and Occupant Restraint Apparatus - A method and apparatus for controlling an occupant restraint apparatus are provided which allow the force applied to a nearby occupant to be optimized in response to collision conditions. In one form, a method for controlling an occupant restraint apparatus includes detecting an obstacle in a travelling direction of a vehicle that may potentially collide with the vehicle; predicting a type of collision between the obstacle detected and the vehicle; setting conditions for expanding an airbag of the vehicle based on the collision type predicted; and controlling the expansion of the airbag and/or gas discharge from the airbag according to the conditions set at the setting step. Detecting the obstacle preferably includes detecting the position and relative speed of the obstacle with respect to the vehicle based on images of views in the travelling direction of the vehicle. | 10-02-2008 |
20090020991 | Airbag and Airbag Apparatus - An airbag and an airbag apparatus in which a vent hole is in a closed state or a slightly open state until an occupant plunges into the airbag and the vent hole becomes to an open state or a widely open state when the occupant plunges into the airbag.

20090121460 | Airbag and Airbag Apparatus - An airbag and airbag apparatus in which a venthole is closed or opened by a small amount until an occupant hits the airbag, and the venthole is opened or opened by a large amount when the occupant hits the airbag. Inner panels | 05-14-2009 |
20090121461 | Airbag and airbag apparatus - An airbag is constructed such that a gas-discharging amount from a venthole becomes largest when an occupant contacts a center portion, in the left and right direction, of an occupant-facing surface of the expanded airbag. In the airbag, a hanging strap couples a center portion of a front panel and a rear panel. A lid body covers an open-and-close venthole from outside the airbag, and the hanging strap is coupled by a tether. In a case that the airbag is expanded, the hanging strap and the tether are tensed, and the lid body is brought to a state to close the open-and-close venthole. A loosening amount of the hanging strap and the tether becomes largest when an occupant contacts the center portion of the front panel to retreat, and an opening amount of the open-and-close venthole also becomes largest. | 05-14-2009 |
20090160164 | Airbag and airbag apparatus - An airbag includes a first and a second inner panel that partition the internal part of the airbag into a first chamber, and a second chamber surrounding the first chamber. Rear-side openings that allow the first chamber to communicate with the second chamber are provided in the second inner panel. Front-side openings are provided in the first inner panel. A sum of the opening areas of the rear-side openings is greater than a sum of the opening areas of the front-side openings. The sum of the opening areas of each of the rear-side openings and the front-side openings is greater than a sum of the opening areas of vent holes. As a result, the gas generated by a gas generator is discharged from the rear-side opening in the radial direction in a large quantity, and the airbag expands quickly in the radial direction. | 06-25-2009 |
20090206587 | Airbag and Airbag Device - An airbag and an airbag device, a vent hole of which remains closed or is made open to a small extent until the internal pressure of the airbag becomes equal or more than predetermined, and becomes opened or is made open to a large extent when the internal pressure of the airbag becomes equal or more than predetermined and also when an occupant comes in contact with the airbag. A vent hole | 08-20-2009 |
20090212538 | Airbag and airbag apparatus - An airbag device includes an outer shell forming an airbag and having a vent hole, a restriction member for restricting gas flow through the vent hole, a first chamber having the vent hole, a second chamber, the inner panel partitioning the airbag into the first and second chambers and having a communication portion, and a tether member for connecting the restriction member and the inner panel. Gas is introduced into the first chamber and then into the second chamber. When the first chamber is filled with gas and the inner panel is tensioned, the tension exceeding a predetermined value is applied to the restriction member so that the vent hole is substantially closed. When the first chamber is not filled with gas and the inner panel loosens, the tension applied to the restriction member does not reach the predetermined value so that the vent hole is opened. | 08-27-2009 |
20090236836 | Airbag and Airbag Apparatus - An airbag capable of starting a tearing operation of a line-shaped connecting portion on an outer periphery side after entire line-shaped connecting portion on an inner periphery side is torn, and an airbag apparatus provided with the airbag. Each of halfway portions disposed halfway between respective center portion and peripheral edge portion in a front panel | 09-24-2009 |
20100001498 | AIRBAG AND AIRBAG DEVICE - An airbag and an airbag device are provided in which an openable-closable vent hole opens or significantly opens even if an object, such as a child seat, comes into contact with a lower portion of the airbag in an inflated state. A covering member ( | 01-07-2010 |
20100032931 | Airbag and airbag apparatus - An airbag to be inflated by gas for a vehicle includes a base member for the airbag, an opening and closing vent provided in the base member, and a discharging gas control member for restraining gas from discharging from the opening and closing vent. The discharging gas control member closes or slightly opens the opening and closing vent when an occupant does not contact a front surface of the airbag facing the occupant when the airbag is inflated. The discharging gas control member opens or widely opens the opening and closing vent so as to allow the gas to be discharged from the opening and closing vent when the occupant contacts the front surface of the airbag, and the front surface is pushed in a direction opposite to the occupant. | 02-11-2010 |

In one form, the airbag, when inflating, has a normally open vent hole disposed in a rear panel in a region extending toward the center of a steering wheel from the rim of the steering wheel and an openable vent hole disposed in a region extending toward the outside of the steering wheel from the rim. The openable vent hole is covered by a cover. The cover and a strap inside the airbag are connected to each other with a tether. From the commencement of inflation of the airbag, the cover is placed over the openable vent hole to close the openable vent hole. | 05-05-2011 |

20150081048 | PARAMETER SETTING DEVICE - A technique that allows determination of appropriate control parameter values automatically. A constraint evaluation indicator setting unit sets, to each of a plurality of additional constraints, a third evaluation indicator obtained by combining a first evaluation indicator that indicates a level of influence on other control parameters when a control parameter is changed, and a second evaluation indicator that indicates weight according to a property including importance and the like. A constraint satisfaction solution retrieve unit retrieves a combination of control parameter values that satisfies constraints. When the constraint satisfaction solution retrieve unit fails to retrieve the combination of control parameter values, a constraint relaxing unit relaxes the additional constraints in accordance with the third evaluation indicator. | 03-19-2015 |
