Abstract
Abstract A seat providing improved comfort includes a pair of moving seating assemblies. A motion mechanism provides each seating assembly with rocking movement and vertical movement. The seating assemblies are provided at a neutral angle that corresponds to the particular application of the seat. The amount of rocking movement and vertical movement is based on the neutral angle. In concert, the neutral angle orientation, rocking movement, and vertical movement cause the weight supported by an occupant's seat bones, posterior, and thighs to be optimally distributed on the seating assembly, improving seating comfort as applied to a given seating environment.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
129 words
A seat comprising: A pair of seating bodies, at least one motion mechanism providing the seating bodies with a rocking motion and a vertical motion including a wave-shaped spring having a first end portion adjacent a concave trough portion adjacent a crest portion adjacent a second end portion, at least one of said first end portion, said trough portion, said crest portion, and said second end portion bearing against at least one of said pair of seating bodies, each seating body having a predetermined neutral angle based on a particular orientation of the seat, wherein the neutral angle is the angle with respect to a horizontal axis orthogonal to the earth's gravity vectors that the seating body resides at when no external forces are present on the seating body.
Claim 2
Dependent Claim
129 words
A seat comprising: A pair of seating bodies, at least one motion mechanism providing the seating bodies with a rocking motion and a vertical motion including a wave-shaped spring having a first end portion adjacent a concave trough portion adjacent a crest portion adjacent a second end portion, at least one of said first end portion, said trough portion, said crest portion, and said second end portion bearing against at least one of said pair of seating bodies, each seating body having a predetermined neutral angle based on a particular orientation of the seat, wherein the neutral angle is the angle with respect to a horizontal axis orthogonal to the earth's gravity vectors that the seating body resides at when no external forces are present on the seating body.
Claim 3
Dependent Claim
24 words
The seat as recited in claim 1 wherein said first end portion is bearing against at least one of said pair of seating bodies.
Claim 4
Dependent Claim
100 words
A seat comprising: a pair of seating bodies, at least one motion mechanism providing the seating bodies with a rocking motion and a vertical motion including a pair of spaced apart helical springs each having a first end bearing against at least one of said pair of seating bodies, each seating body having a predetermined neutral angle based on a particular orientation of the seat, wherein the neutral angle is the angle with respect to a horizontal axis orthogonal to the earth's gravity vectors that the seating body resides at when no external forces are present on the seating body.
Claim 5
Dependent Claim
100 words
A seat comprising: a pair of seating bodies, at least one motion mechanism providing the seating bodies with a rocking motion and a vertical motion including a pair of spaced apart helical springs each having a first end bearing against at least one of said pair of seating bodies, each seating body having a predetermined neutral angle based on a particular orientation of the seat, wherein the neutral angle is the angle with respect to a horizontal axis orthogonal to the earth's gravity vectors that the seating body resides at when no external forces are present on the seating body.
Claim 6
Dependent Claim
116 words
A seat comprising: a pair of seating bodies, at least one motion mechanism providing the seating bodies with a rocking motion and a vertical motion including a first coil spring positioned relatively nearer a center of at least one of said pair of seating bodies and a second coil spring positioned relatively nearer an end of at least one of said pair of seating bodies, each seating body having a predetermined neutral angle based on a particular orientation of the seat, wherein the neutral angle is the angle with respect to a horizontal axis orthogonal to the earth's gravity vectors that the seating body resides at when no external forces are present on the seating body.
Claim 7
Dependent Claim
116 words
A seat comprising: a pair of seating bodies, at least one motion mechanism providing the seating bodies with a rocking motion and a vertical motion including a first coil spring positioned relatively nearer a center of at least one of said pair of seating bodies and a second coil spring positioned relatively nearer an end of at least one of said pair of seating bodies, each seating body having a predetermined neutral angle based on a particular orientation of the seat, wherein the neutral angle is the angle with respect to a horizontal axis orthogonal to the earth's gravity vectors that the seating body resides at when no external forces are present on the seating body.
Claim 8
Dependent Claim
128 words
A seat comprising: a pair of seating bodies, at least one motion mechanism providing the seating bodies with a rocking motion and a vertical motion including a spring having a plate and at least one leg extending from said plate to a distant end of said spring, said at least one leg having a sinusoidal shape, at least one of said distant end and said plate bearing against at least one of said pair of seating bodies, each seating body having a predetermined neutral angle based on a particular orientation of the seat, wherein the neutral angle is the angle with respect to a horizontal axis orthogonal to the earth's gravity vectors that the seating body resides at when no external forces are present on the seating body.
Claim 9
Dependent Claim
128 words
A seat comprising: a pair of seating bodies, at least one motion mechanism providing the seating bodies with a rocking motion and a vertical motion including a spring having a plate and at least one leg extending from said plate to a distant end of said spring, said at least one leg having a sinusoidal shape, at least one of said distant end and said plate bearing against at least one of said pair of seating bodies, each seating body having a predetermined neutral angle based on a particular orientation of the seat, wherein the neutral angle is the angle with respect to a horizontal axis orthogonal to the earth's gravity vectors that the seating body resides at when no external forces are present on the seating body.
Claim 10
Dependent Claim
