US 6,595,586 B2 · Two platform motion seat

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.
