<p>A headrest (210), in one embodiment, includes a support member (230) having a center portion and an end portion (238a, 238b) which is integrally formed and which extends angularly from the center portion. A wing member (235a, 235b) is coupled to the end portion by a hinge mechanism (234a, 234b) that has sufficient friction to maintain any of a plurality of positions under a load of a human head leaning against the wing member, yet yields when a greater load is applied.</p> |
