ABSTRACT:
A seat construction including a composite inner/outer frame to which at least two seat pans are secured. The composite frame includes three horizontal cross members, located at the front ends of bottom portions of the seat pans, at the junctions of the bottom portions and back portions of the seat pans, and at the top ends of the back portions of the seat pans. A pair of boomerang-shaped side members are fixed at their distal ends and their bent centers to the opposing ends of the cross members and an intermediate member is fixed to the mid-ways of the cross members, so that an inner frame is formed by the side members, cross members, and intermediate member. The side members the front cross member and the intermediate frame member are covered by their corresponding outer frame members to construct the composite inner/outer frame which is light in weight but rigid in construction.
