摘要:
A headgear assembly (30) includes a first sub-portion (D1) formed from a generally planar first material and a second sub-portion (A1, B1, C1) formed from a generally planar second material. The second sub-portion is coupled along an edge face to an edge face of the first sub-portion without overlapping the first sub-portion. The second material differs from the first material by at least one physical property.
