Abstract

An improved multiple seat chair structure is disclosed which includes a pair of longitudinally spaced, vertically oriented, end support members; a longitudinally extending brace member fixed to and interconnecting the end support members; at least one intermediate support member positioned between the end support members, each of the intermediate support members including a vertically extending leg member thereon having an upper end portion; first and second seat sections carried by the various support members, the seat sections each including first and second side rail members thereon and a seat member extending between and supported by the side rail members; and at least one generally wedge-shaped fitting rigidly interconnecting the leg member, the brace member and at least one of the side rail members from each of two of the seat sections. The fitting preferably includes a first, generally planar, surface thereon on which the side rail members are seated; elements for fastening the side rail members to the first surface; a second, generally partially cylindrical, surface in which a portion of the brace member is seated; a third, generally planar, surface thereon on which the remainder of the brace member is seated and on which the leg member is seated; and elements for fastening the brace member and the leg member to the third surface.
