Abstract

Abstract Padding for use on vehicle doors for protection of occupants in side impact accidents is composed of a plurality of cells. Each cell is filled with air and sealed except for an orifice. The flow of the air through the orifice provides the damping required to absorb the energy of the impacting occupant. Each cell contains a spring, usually in the form of foam rubber, to maintain the cell in its inflated shape. The plurality of cells provides for better control over the motion of the occupant. The padding can also be used on any surface of the passenger compartment including knee bolsters, headrests, A and B pillars, roofs structures, roof and seats.

Claims Analysis

Total Claims: 20
Claim 1
Independent Claim 131 words
A padding for cushioning and absorbing energy from an object which impacts against it, said padding comprising a plurality of padding cells arranged substantially side by side to form a cushion surface, each padding cell including: (a) an enclosed chamber containing a gas and having side walls formed of substantially impervious flexible material and an end wall having a flow restrictor means for controlling the flow of said gas therethrough, said chamber being adapted to be collapsed from an initial position with full internal volume to a final, collapsed position with substantially less internal volume; and (b) means for restoring said chamber to its initial position, said means being disposed away from said flow restrictor means to permit the unimpeded flow of said gas to and through said flow restrictor means.
Claim 2
Dependent Claim 131 words
A padding for cushioning and absorbing energy from an object which impacts against it, said padding comprising a plurality of padding cells arranged substantially side by side to form a cushion surface, each padding cell including: (a) an enclosed chamber containing a gas and having side walls formed of substantially impervious flexible material and an end wall having a flow restrictor means for controlling the flow of said gas therethrough, said chamber being adapted to be collapsed from an initial position with full internal volume to a final, collapsed position with substantially less internal volume; and (b) means for restoring said chamber to its initial position, said means being disposed away from said flow restrictor means to permit the unimpeded flow of said gas to and through said flow restrictor means.
Claim 3
Dependent Claim 35 words
The padding defined in claim 1, wherein said cells have a maximum width, between opposite side walls, which is not substantially greater than the size of the object which is expected to impact against it.
Claim 4
Dependent Claim 13 words
The invention in accordance with claim 1 wherein said restoring means comprises foam.
Claim 5
Dependent Claim 13 words
The invention in accordance with claim 1 wherein said restoring means comprises fibers.
Claim 6
Dependent Claim 16 words
The invention in accordance with claim 1 wherein said restoring means comprises at least one spring.
Claim 7
Dependent Claim 17 words
The invention in accordance with claim 1 wherein said restrictor means comprises a hole in said chamber.
Claim 8
Dependent Claim 23 words
The invention in accordance with claim 1 wherein the flow through said restrictor means is substantially proportional to the viscosity of said gas.
Claim 9
Dependent Claim 26 words
The invention in accordance with claim 1 wherein means are provided to vary the area of said restrictor means in response to pressure inside said chamber.
Claim 10
Dependent Claim 23 words
The invention in accordance with claim 1 wherein the flow through said restrictor means is substantially controlled by the inertia of the gas.
Claim 11
Dependent Claim 18 words
The invention in accordance with claim 1 wherein said padding is disposed on to a motor vehicle door.
Claim 12
Dependent Claim 19 words
The invention in accordance with claim 1 wherein said padding is disposed on to a motor vehicle knee bolster.
Claim 13
Dependent Claim 18 words
The invention in accordance with claim 1 wherein said padding is disposed on to a motor vehicle headrest.
Claim 14
Dependent Claim 19 words
The invention in accordance with claim 1 wherein said padding is disposed on to a motor vehicle roof structure.
Claim 15
Dependent Claim 20 words
The invention in accordance with claim 1 wherein said padding is disposed on to a motor vehicle roof support pillar.
Claim 16
Dependent Claim 23 words
The invention in accordance with claim 1 wherein at least one chamber has restrictor means of different size than that of another chamber.
Claim 17
Dependent Claim 17 words
The invention in accordance with claim 1 wherein said padding is incorporated in a motor vehicle seat.
Claim 18
Dependent Claim 15 words
The invention in accordance with claim 16 wherein said seat additionally comprises an anti-submarining structure.
Claim 19
Dependent Claim 15 words
The invention in accordance with claim 1 wherein said gas is maintained above atmospheric pressure.
Claim 20
Dependent Claim 17 words
The invention defined in claim 1 wherein said chamber contains substantially no volume in its collapsed position.
