Abstract
Abstract a seating structure provides improved comfort and includes a single, pair, or multiple numbers of moving seating assemblies with independent platforms, especially suited for the automotive or aircraft seating environments. A motion mechanism provides each seating assembly with at least one of total rocking, vertical up and down movement, lateral, and limited slight turning movement and in one embodiment generally constrains the seat members of the seat assemblies from interference with each other. The seating assemblies are provided at a neutral angle that corresponds to the particular application of the seat. Independent up and down movement, and rocking, improves seating comfort health, and safety especially as applied to a seating environment, where a user is likely to be seated for an extended period, such as in an automobile or aircraft.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
157 words
A seat comprising: a central support; a first and a second adjacently located seating bodies, at least one motion mechanism connected between said central support and each of said first and said second adjacently located seating bodies, said motion mechanism for providing said at least one of a rocking motion, a vertical up and down motion, a limited turning motion, and a lateral motion, each of said first and said second adjacently located seating bodies having a predetermined neutral angle, 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; and a third seating body located adjacent said first and said second adjacently located seating bodies for providing said at least a vertical up and down motion, said third seating body for providing additional load characteristics to a user of said seat.
Claim 2
Dependent Claim
157 words
A seat comprising: a central support; a first and a second adjacently located seating bodies, at least one motion mechanism connected between said central support and each of said first and said second adjacently located seating bodies, said motion mechanism for providing said at least one of a rocking motion, a vertical up and down motion, a limited turning motion, and a lateral motion, each of said first and said second adjacently located seating bodies having a predetermined neutral angle, 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; and a third seating body located adjacent said first and said second adjacently located seating bodies for providing said at least a vertical up and down motion, said third seating body for providing additional load characteristics to a user of said seat.
Claim 3
Dependent Claim
45 words
The seat of claim 1 , and further comprising a fourth seating body located adjacent said third seating body for providing said at least a vertical up and down motion and for accepting distribution of said additional load characteristics to said user of said seat.
Claim 4
Dependent Claim
14 words
The seat of claim 1 , wherein the neutral angle is approximately seven degrees.
Claim 5
Dependent Claim
64 words
The seat of claim 1 , wherein said first and said second adjacently located seating bodies provide an ischial tuberosities target area, said ischial tuberosities target area defined as the ideal location on the seating body for an occupant to sit, the ischial tuberosities target area extending about midway of a length of each of said first and said second adjacently located seating bodies.
Claim 6
Dependent Claim
23 words
The seat of claim 1 , wherein said first and said second adjacently located seating bodies are each covered by a single cushion.
