In a knee protecting airbag device (M), an airbag () folded and housed below a steering column () is expanded and inflated while rising from the lower side of the steering column () along a column cover lower surface () during an inflation process. The shape of the airbag having completed the inflation is in a generally plate shape capable of covering at least the lower surface of the column cover. Even if the knee of the driver comes close to the column cover when the driver depressing a brake pedal, therefore, the airbag being expanded and inflated goes smoothly into the clearance between the knee of the driver and the column cover lower surface. The airbag having completed the expansion and inflation protects the knee of the driver properly so that the knee may not interfere with the column cover.

Knee protecting airbag device

An airbag system includes an airbag, and the airbag includes an airbag body having a passenger-side wall portion that is arranged at a passenger side when having completed deploying and inflating, and a slip cloth that is disposed at an outer surface side of the passenger-side wall portion. The slip cloth formed in a loop shape an axial direction of which is in a left and right direction includes: a front panel portion arranged at a passenger side; an upper back panel portion extending downward from an upper end of the front panel portion; and a lower back panel portion extending upward from a lower end of the front panel portion, and a lower end of the upper back panel portion and an upper end of the lower back panel portion are mutually approximated, and joined to the passenger-side wall portion.

Airbag system

A side airbag apparatus for vehicle has an airbag and an inflator. An upper chamber, a lower chamber, and an intermediate chamber are defined by a seam in the airbag. When the airbag is deployed, the upper chamber corresponds to a shoulder of an occupant, the lower chamber corresponds to a lumbar region of the occupant, and the intermediate chamber corresponds to a thorax of the occupant. The seam guides gas from the inflator to the upper and lower chambers such that the upper and lower chambers are substantially simultaneously inflated, and the intermediate chamber is inflated after a delay. The thickness of the intermediate chamber is less than the thicknesses of the upper and lower chambers. As a result, the occupant of the vehicle is effectively protected.

Side airbag apparatus

In a knee protecting airbag device of the present invention, an airbag is folded and housed on the front side of the knees of a seated passenger. The airbag is protruded rearward of a vehicle from a protruding opening and expanded and inflated upward, when an inflating gas flows in. And, the airbag is arranged on the front side of the knees of the passenger between a member on the body side and the knees of the passenger thereby to protect the knees of the passenger. The protruding opening has a transverse width size set within a range of &#x215b; to &#x2154; of the transverse width size of the airbag having completed its expansion and inflation.

The head-protecting airbag device (M) includes an airbag () provided with a gas admissive portion () and a non-admissive portion (). The gas admissive portion () includes a gas feed passage () for feeding inflation gas G toward both front and rearwards of the vehicle, and a plurality of vertical chambers () juxtaposed along front-rear direction of the vehicle. Each of the vertical chambers () includes a communication port at its upper end for communicating with the gas feed passage (). The substantial lengths of a vehicle's outer wall () and an inner wall () of the airbag () are differentiated from each other by a belt () in the periphery () of the communication port (). Thus the periphery () of the communication port () guides inflation gas (G) obliquely down and toward the vehicle's exterior (O) when inflation gas (G) flows into the vertical chamber () via the communication port. The head-protecting airbag device (M) is made compact and improves workability in the mounting work on the vehicle while ensuring downward deployment of the airbag () along the window (W).

Head-protective airbag device

A first airbag apparatus of the present invention has an airbag module, which includes an airbag and an inflator, and a displacement mechanism, which displaces the airbag module. The displacement mechanism displaces the airbag module from an original position to a predetermined position when a collision of the vehicle is predicted and displaces the airbag module from the predetermined position to the original position when the predicted collision is avoided. A second airbag apparatus of the present invention has the airbag module and the displacement mechanism, which displaces a support member. The support member displaces the airbag from the original position to the predetermined position before the airbag is deployed. The deployed airbag is supported between the support body that is displaced to the predetermined position and an occupant.

Airbag apparatus

An airbag apparatus has an airbag, an inflator, a cover and an opening mechanism. When an impact the magnitude of which is greater than a predetermined value is applied to the vehicle, the inflator supplies gas to the airbag. The cover covers the airbag. The opening mechanism opens the cover prior to inflation of the airbag.

Air bag device for knee protection

A side air bag device () includes an inflator () arranged in a backrest () of a seat () to discharge gas, an air bag () having an upper chamber () and a lower chamber (), which are each inflated by discharging gas, and an impact reducing means () for reducing impact that is applied to a passenger when the air bag contacts the passenger during inflation of the air bag.

Side air bag device

A knee protecting airbag device in which a folded airbag and an inflator are housed and held in a case. In the inflator, a connection portion to be connected with a connector having leadwires connected is exposed to the outside of the case through insert holes formed in the airbag and in the case. The through hole of the case has an internal diameter size smaller than the external diameter size of the general portion of the inflator near the connection portion of the inflator.
