Claim 2
Dependent Claim
87 words
An air bag device for an automotive vehicle, comprising: an air bag module disposed in an instrument panel of the vehicle, said air bag module including an air bag and an air bag case; an air bag lid disposed so as to open when said air bag in said air bag module is inflated; and a plate for absorbing impact being connected to said air bag case, said plate comprising a wall of said air bag module extending toward an inner surface of said air bag lid.
Claim 3
Dependent Claim
23 words
An air bag device as defined in claim 1, wherein said plate is attached to an upper wall of said air bag case.
Claim 4
Dependent Claim
26 words
An air bag device as defined in claim 2, further comprising a hinge which is connected between said air bag lid and said air bag module.
Claim 5
Dependent Claim
19 words
An air bag device as defined in claim 2, wherein said plate comprises a material capable of plastic deformation.
Claim 6
Dependent Claim
109 words
An air bag device as defined in claim 1, wherein said air bag case has an opening allowing inflation of said air bag toward said air bag lid, and said air bag device includes a space formed between the opening and the inner surface of the air bag lid, the space being sized such that a distance between an upper portion of said air bag case and an upper portion of said air bag lid is longer than a distance between a lower portion of said air bag case and a lower portion of said air bag lid, and said plate extending into an upper portion of the space.
Claim 7
Dependent Claim
54 words
An air bag device as defined in claim 5, wherein said air bag case is shaped so that an edge of said air bag case defining a portion of the opening slants in an upwardly and forward direction of the vehicle when viewed from a direction transverse to a longitudinal axis of the vehicle.
Claim 8
Dependent Claim
65 words
An air bag device as defined in claim 1, wherein said air bag case has an opening allowing inflation of said air bag toward said air bag lid; said plate has an end portion extending toward said air bag lid which is curved upwardly and has a middle portion having a ridge adjacent to an edge of said air bag case for locating said plate.
Claim 9
Dependent Claim
22 words
An air bag device as defined in claim 7, wherein said plate has another end portion positioned on said air bag case.
Claim 10
Dependent Claim
37 words
