To provide an airbag device and a steering wheel capable of improving the operational feeling of horn. An airbag device comprises: an airbag unithaving an airbag, an inflatorfor inflating the airbag, and a coverwhich is disposed to cover said airbag in the folded state, wherein as the coveris pressed, the airbag unitis moved in the pressing direction; a supporting platewhich is fixed to a steering wheel; three springs-for biasing the airbag unitin a direction opposite to the pressing direction; and three horn switches-which are located outside of the springs-in the radial direction of the steering wheel and close to the surface of the coverin relation to the springs-

Airbag device and steering wheel

An airbag includes a front portion having an upper part for receiving a head of the occupant, a middle part and a lower part. The upper part has an upwardly protruding curved edge without a linear portion, and two laterally protruding upper curved edges. The middle part has two laterally inwardly curved middle side edges extending smoothly from the laterally protruding upper curved edges. The lower part haw two laterally inwardly and downwardly curved lower side edges, and a downwardly protruding curved edge without a linear portion. The lower part has a lateral width greater than that of the upper and middle parts to thereby form laterally projecting portions for receiving occupant's arms. The downwardly extending curved edge at the lower part has a curvature greater than that of the upwardly extending curved edge at the upper part.

Airbag and airbag system

An airbag device where a case and a lid are connected by engaging a hook of the case with a hook hole in the lid and where the hook moves in the hook hole toward the vehicle interior side when the lid recedes. Energy absorption characteristics when the lid recedes are improved by a simple structure. The hook () used for connection to the lid () and provided at the case () is engaged with the hook hole () of the lid (). The hook hole () is a long hole elongated in the vertical direction, and in the middle of the long hole is provided a partition-like section () for partitioning the inside of the hook hole () into the upper half and the lower half. The hook () is engaged with that portion of the hook hole () which is lower than the partition-like section (). As the lid () recedes, the hook () moves upward in the hook hole () while cutting the partition-like section ().
