Abstract
Abstract A seat support for a vehicle including a combination beam interconnected with the vehicle at one end and having a seat mounted on its opposite end. The combination beam includes longitudinally extending load support members of relatively high modulus of elasticity spaced from each other along at least a portion of their length to define a gap. An elastomeric shock absorbing material is positioned in the gap. The material being deformed responsive to relative movement of the structural members of the beam when the beam is bent under load such that the material absorbs shock and vibration.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
161 words
A seat support for a vehicle comprising: a combination beam; means for mounting said combination beam on said vehicle located at one end of said combination beam; and, seat means mounted on said combination beam distal from said vehicle mounting means; said combination beam including; a first portion having a high modulus of elasticity fixedly connected to said vehicle and a second portion also having a high modulus of elasticity mounted to move with respect to said first portion in response to loads placed on said beam; said high modulus of elasticity portions including a rigid foam core covered by a skin of resin bound fibers; said first and second high modulus of elasticity portions including a third elastomeric portion sandwiched therebetween such that the movement of said second portion with respect to said first portion causes said third portion to be deformed and said third elastomeric portion slows the movement of said second portion with respect to said first portion.
Claim 2
Dependent Claim
161 words
A seat support for a vehicle comprising: a combination beam; means for mounting said combination beam on said vehicle located at one end of said combination beam; and, seat means mounted on said combination beam distal from said vehicle mounting means; said combination beam including; a first portion having a high modulus of elasticity fixedly connected to said vehicle and a second portion also having a high modulus of elasticity mounted to move with respect to said first portion in response to loads placed on said beam; said high modulus of elasticity portions including a rigid foam core covered by a skin of resin bound fibers; said first and second high modulus of elasticity portions including a third elastomeric portion sandwiched therebetween such that the movement of said second portion with respect to said first portion causes said third portion to be deformed and said third elastomeric portion slows the movement of said second portion with respect to said first portion.
Claim 3
Dependent Claim
26 words
The seat support of claim 1, wherein said means for mounting said combination beam on said vehicle includes means for cantilevering said beam from said vehicle.
Claim 4
Dependent Claim
15 words
The seat support of claim 1, wherein said combination beam is curved along its length.
Claim 5
Dependent Claim
39 words
The seat support of claim 1, wherein the first and second portions of said combination beam are fixedly interconnected with each other along their length in an area spaced from the connection of said first portion to said vehicle.
Claim 6
Dependent Claim
38 words
The seat support of claim 1, wherein the first and second portions of said combination beam are spaced from each other in the area of the connection of said first portion to said vehicle to define a gap.
Claim 7
Dependent Claim
28 words

Claim 8
Dependent Claim
31 words
The seat support of claim 6, wherein the movement of said second portion of said beam with respect to said first portion causes said third portion to be deformed in shear.
Claim 9
Dependent Claim
193 words
A seat support for a vehicle comprising: a combination beam; means for mounting said combination beam on said vehicle located at one end of said combination beam; and, seat means mounted on said combination beam distal from said vehicle mounting means; said combination beam including: a first portion having a high modulus of elasticity fixedly connected to said vehicle and a second portion also having a high modulus of elasticity mounted to move with respect to said first portion in response to loads placed on said beam; said first and second high modulus of elasticity portions a third elastomeric portion sandwiched therebetween such that the movement of said second portion with respect to said first portion causes said third portion to be deformed and said third elastomeric portion shows the movement of said second portion with respect to said first portion; said high modulus of elasticity portions including a rigid foam core covered by a skin of resin bound fibers; and, said rigid foam core comprising a polyurethane foam core, said skin of resin bound fibers comprising a skin of epoxy resin bound fiberglass and wherein said elastomeric portion is a polyurethane elastomer.
Claim 10
Dependent Claim
193 words
A seat support for a vehicle comprising: a combination beam; means for mounting said combination beam on said vehicle located at one end of said combination beam; and, seat means mounted on said combination beam distal from said vehicle mounting means; said combination beam including: a first portion having a high modulus of elasticity fixedly connected to said vehicle and a second portion also having a high modulus of elasticity mounted to move with respect to said first portion in response to loads placed on said beam; said first and second high modulus of elasticity portions a third elastomeric portion sandwiched therebetween such that the movement of said second portion with respect to said first portion causes said third portion to be deformed and said third elastomeric portion shows the movement of said second portion with respect to said first portion; said high modulus of elasticity portions including a rigid foam core covered by a skin of resin bound fibers; and, said rigid foam core comprising a polyurethane foam core, said skin of resin bound fibers comprising a skin of epoxy resin bound fiberglass and wherein said elastomeric portion is a polyurethane elastomer.
