Active response seating system
View Patent ↗Novel Seats having a plurality of defined zones for supporting the human anatomy are disclosed. Seats including one or more recoil shields and/or inserts to assist in supporting or isolating certain desired portions of the human anatomy, as well as seats including both seat back structures and seat pan structures, with one or both including zoned configurations designed to support and stabilize specific structures of the human anatomy in a defined manner are also disclosed. The novel seats are useful, inter alia, for individually supporting certain anatomical areas and provide seat zones that collectively support, cradle and permit the human anatomy to be supported in a comfortable manner.
