Vehicle seat assembly having layered seating system

摘要

A vehicle seat cushion composite is provided with a structural layer adapted to be mounted within a vehicle to provide support to an occupant. The structural layer has at least two edge regions provided proximate two edges of the structural layer and an inner region at least partially bound within the at least two edge regions. The at least two edge regions have a plurality of concave channels. A cushion layer is adjacent to the structural layer and has a plurality of concave projections sized to be received within the plurality of concave channels of the structural layer for minimizing lateral movement of the cushion layer relative to the structural layer proximate the edge regions.
