Abstract
Abstract A mounting arrangement for a vehicle air bag comprises a mounting bracket affixed to a component of the vehicle, a base plate having a mounting portion on which an air bag and an inflator are mounted, and a plurality of fasteners connecting the base plate to the bracket. Plastically deformable structures associated with the fasteners and the base plate are arranged such that the mounting portion of the base plate is displaceable in a direction away from the mounting bracket in response to the forces imposed on the base plate at the end of the development of the air bag.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
102 words
A mounting arrangement for a vehicle air bag comprising a mounting bracket affixed to a component of the vehicle, a base plate having a mounting portion on which an air bag and an inflator are mounted, and a plurality of fasteners connecting the base plate to the bracket, characterized in that there are plastically deformable structures associated with the fasteners and the base plate such that the mounting portion of the base plate is displaceable in a direction away from the mounting bracket in response to the forces imposed on the base plate at the end of development of the air bag.
Claim 2
Dependent Claim
102 words
A mounting arrangement for a vehicle air bag comprising a mounting bracket affixed to a component of the vehicle, a base plate having a mounting portion on which an air bag and an inflator are mounted, and a plurality of fasteners connecting the base plate to the bracket, characterized in that there are plastically deformable structures associated with the fasteners and the base plate such that the mounting portion of the base plate is displaceable in a direction away from the mounting bracket in response to the forces imposed on the base plate at the end of development of the air bag.
Claim 3
Dependent Claim
31 words
A mounting arrangement according to claim 1 and further characterized in that the deformable structures are portions of the base plate located proximate to the fasteners and arranged to deform plastically.
Claim 4
Dependent Claim
75 words
A mounting arrangement according to claim 2 and further characterized in that said portions of the base plate are mounting tabs oriented generally parallel to the direction of said forces, in that each tab has a hole receiving a fastener and in that a portion of each tab between the fastener and the mounting portion of the base plate has holes defining plastically deformable segments of the tab that elongate in response to said forces.
Claim 5
Dependent Claim
72 words
A mounting arrangement according to claim 2 and further characterized in that said portions of the base plate are mounting tabs oriented generally parallel to the direction of said forces, in that each tab has a hole receiving a fastener, and in that a portion of each tab between the fastener and the distal end has an opening into which deformable protrusions project, the protrusions being engageable and deformable by the fastener.
Claim 6
Dependent Claim
52 words
A mounting arrangement according to claim 1 and further characterized in that the deformable structures are attachment clips having initially bent leg portions, the clips being fastened between the bracket and the mounting plate and the leg portions being plastically deformable to reduce or eliminate the bends in response to said forces.
Claim 7
Dependent Claim
54 words
A mounting arrangement according to claim 1 and further characterized in that the base plate has holes for the fasteners located in portions lying generally orthogonally to the direction of said forces and in that slits in the base plate on opposite sides of each hole define plastically extensible segments of the base plate.
Claim 8
Dependent Claim
46 words
A mounting arrangement according to claim 1 and further characterized in that the deformable structures comprise a generally tubular plastically deformable spacer received by a shank of each fastener and engaged between an abutment on each fastener and either the base plate or the mounting bracket.
Claim 9
Dependent Claim
42 words
A mounting arrangement according to claim 7 and further characterized in that the deformable spacers are tubes having slits defining a plurality of deformable strands, each strand being initially slightly bent and being adapted to bend further in response to said forces.
Claim 10
Dependent Claim
29 words
A mounting arrangement according to claim 7 wherein the abutments of the fasteners have cam surfaces engaging the tubes such as to expand them in response to said forces.
