  • the flanges of the vertical portions 24, 25 form bifurcate portions, on the inside of which is arranged low projections 28.
  • the height of the horizontal portion 23 is adjusted with respect to the bottom surfaces of the recesses 27 in a manner whereby the partitions 26, which as earlier mentioned are to be considered as extensions of the flanges of the horizontal portion 23, coincide with the height position of the recesses 14 in the side pieces 2, 2, FIG. 9, when the cross members 20, 21 are assembled in position in the manner to be hereinafter described.
  • the cross members 21 and 21' are also identical and the horizontal portion 23 is placed symmetrically and centrally between the ends of the vertical portions 24 and 25.
  • FIG. 1 illustrates a seat 30 and a back support member 31 as an integral part, the seat and the back support member being shown in ghost lines for the sake of illustration, and are arranged between the beams 20, 20'. Also in ghost lines is illustrated a stiffening member 32 in the seat 30, the member 32 being, for example, a slab of suitably rigid but slightly resilient material. As illustrated in FIG. 8, the slab 32 is inserted in the U-shaped beam 24), which forms a secure attachment therefor- On the opposite side, the slab 32 is held in position in the seat by a seam, indicated in FIG. 1 by dotted lines.
