Abstract
Abstract Laminated cushion formed of a plurality of alternating, relatively rigid and relatively soft layers of resilient foam has a higher compression rate in the direction of an axis parallel to the planes of the layers than in the transverse direction. Thus, when the cushion is positioned with the planes of the layers arranged vertically, the cushion is usable as an armrest. When it is positioned with the planes of the layers arranged horizontally, it is usable as a pillow. In a modification, the cushion can be added to the side of a conventional armrest on an aircraft passenger seat to increase the width thereof while being easily compressed sideways to accommodate larger framed passengers.

Claim 1
Independent Claim
142 words
In combination, a multi-passenger seat and an armrest for separating a pair of adjacent seating positions thereon, the armrest having a pair of armrest portions on either side of a rigid central support member, said armrest portions offering greater resistance to loading in a vertical direction than in a sideways direction so that their deflection for a given loading is at least three times greater sideways then downwardly, said armrest portions each comprising a plurality of spaced layers of relatively rigid foam and a plurality of spaced layers of relatively soft foam, said soft foam layers having a thickness not exceeding about one inch and said rigid foam layers being of lesser thickness, said rigid foam layers and said soft foam layers being alternately bonded to each other in vertical planes and attached to each side of said rigid central support member.
