Abstract: A curtain airbag capable for preventing occupant ejection from a vehicle, particularly in the vicinity of a rearmost seat, while reducing the output required of an inflator associated with the airbag. The curtain airbag is stored at an upper position on a side surface portion of the occupant compartment of the vehicle, so as to be inflated and deployed along the side surface portion. The curtain airbag includes an inflation region and a wide portion in the form of non-inflatable cloth. The wide portion is attached to a rear edge portion of the inflation region and also attached to at least one point of the vehicle rearward of a front-side pillar, the front-side pillar being located forward of rearmost side window. The wide portion has a shape that allows it to be strained, by the inflated and deployed inflation region, into a generally planar configuration over an assumed strike area of the rearmost side window.

Abstract: An airbag for a knee airbag apparatus which is rapidly deployed upward between the knees of a passenger and instrument panel includes a front panel; a rear panel coupled to the front panel to form an inflation chamber; and a hinge portion having a thin inflation thickness at a position corresponding to a housing connecting portion, at which the instrument panel is coupled to the housing, when the airbag is inflated.

Abstract: A vehicle braking arrangement includes a braking plate connected to a vehicle by a link arrangement. The braking plate is movable from a rest position to a braking position where contact is made with the ground, and includes a sealing rim arranged to at least partially contact the ground such that an at least partly enclosed volume is formed. The vehicle braking arrangement includes a low pressure container connected to the volume via a valve assembly. Air pressure in the low pressure container is below the air pressure of ambient air in the rest position of the braking plate. The valve assembly is arranged to be opened when the braking plate is in the braking position such that the pressure is lowered in the volume and the braking plate is pressed against the ground by a conferred pressure difference between air outside the volume and air in the volume.

Abstract: A knee airbag apparatus includes a folded airbag. The folded airbag includes an upper folded part formed by rolling an upper end of the airbag toward a lower end of the airbag after the upper end of the airbag is folded on the front panel; and a lower folded part disposed to be adjacent to the upper folded part by folding at least once a lower portion of the airbag in a direction that is opposite to the rolling direction of the upper folded part. The folded airbag includes a side folded part formed by folding a side portion of the airbag before the upper folded part is formed or by folding both sides of the upper and lower folded parts after the upper and lower folded parts are formed.

Abstract: Disclosed is a curtain airbag module including a curtain airbag cushion, an inflator of supplying and inflating gas into the curtain airbag cushion, and a lamp bracket fixed on a vehicle panel to support the curtain airbag cushion which is integrally provided with a lamp pattern to deploy the curtain airbag cushion into a vehicle without deploying the curtain airbag cushion into a pillar trim of a vehicle in the deployment of the curtain airbag cushion by driving the inflator. The lamp pattern wraps up at least a portion of the folded curtain airbag cushion. The lamp pattern initially wrapping up the folded curtain airbag cushion guides the curtain airbag cushion to the interior of the vehicle when the curtain airbag cushion is deployed, thereby preventing the curtain airbag cushion from being inserted into the pillar trim, so that the curtain airbag cushion is stably deployed.

Abstract: A self-testing method of a frequency-modulated continuous-wave(FMCW) radar device. A transmission signal having an object detection signal and a self-test signal superimposed on the object detection signal is transmitted. The self-test signal represents at least one virtual target. A reception signal is received. The reception signal is a received version of the transmission signal. Presence of the at least one virtual target in the reception signal is determined. A lack of presence of the virtual target in the reception signal provides an indication of hardware failure of the FMCW radar device.
