McGowen, Pittsburgh, Pa., assignor to The‘ McKay Company,‘ Pittsburgh, Pa., a corporation oi’ Pennsylvania; Application May 29, 1937, Serial No. 145,583 3 Claims. - (01. 155-194) My invention relates to improvements in chairs and other types of seating structures, and has for its object the provision of a chair structure of generally simpli?ed and improved form which can 5 be made cheaply and conveniently assembled, and which, nevertheless, will be. of light-weight and sturdy construction. ‘The present invention is directed more particularly to the leg portions of a chair and the connection thereto of a seat 10 board or cushion; , As shown on the accompanying drawing, Figure 1 is a side view of a chair; Fig. 2 is a face view devices 8 and 9 are not subjected to severe bend ing strains. ~ Back bars I 2 may also be formed of tubular stock, and are welded at l3 to the seat bar por- - tions 1. The upper ends of the back bars l2 are 5 ?attened‘ somewhat and connected to a back member l4 by screws. The ends of the bars l2 that are welded to the bar portions 1 have ex- : tended contact therewith, thereby serving to brace the bar portions 1 against transverse rocking 10 movements. I claim as my invention: thereof; Fig. 3 is a bottom plan view, and Fig. 4 is ' ‘,1. A chair comprising a seat member and a a sectional view taken on the line IV—IV of Fig. 3. pair of leg members disposed adjacent to opposite 15 The leg structure is here shown as formed of . edges of the seat, each having two legs connected 15 ‘ two tubes each bent‘so as to form a front leg 5, at their upper ends by integral transverse seat a rear leg 6 and a seat bar portion 7. » Each leg bar portions which are de?ected laterally at points unit may be formed of- a single piece or of a plu- ' intermediate the legs and extend from the edges rality of pieces connected in unitary relation, and 20 may be formed of material other than metal tubes. An important feature of my invention involves the bending inwardly of the seat bar portions 1, as shown more clearly in‘Figs. 2 and 3. These in 25 wardly bent seat bar portions are secured by screws or bolts 8 and 9 to a board or plate III that is covered with a pad or upholstering H. Open framework or other types of seats could, of course, be substituted for the board ill. 30 By reason of the angularity or lateral spread of the seat bars 1 and theirconnection to the seat _ board, it will be seen that the legs are thereby strongly braced and held in rigid relationship to the seat and to eachother, especially if the seat 35 bars are de?ected inwardly to nearly the center ‘ of the seat board, as shown. This construction of. the seat member to points more closely adja cent to the seat center than to the edges of the seat, to form base-like extensions to support the legs against tilting relative to said seat; and se-' cured to the seat member. 2. A chair comprising a seat member, a pair of leg members respectively disposed adjacent to opposite edges of the seat and each member hav ing two legs formed with a transverse seat bar portion',.the two seat bar portions being bent in opposite directions and having ?at contact throughout their lengths with the bottom of the seat, and means for securing the said seat bar 30 portions to the seat. . 3. A chair comprising a seat member, a pair of leg members respectively disposed adjacent to opposite edges of the seat and each member hav- , 5 ing two legs formed with a transverse seat bar portiorrthe two. seat bar portions being bent in opposite directions, in a plane parallel to the is or further utility in that the angular seat bar portions 1 constitutebase extensions or ?anges ' underside of the seat, and means for securing the 40 for each of the legs 5 and 6, which prevent tilting seat bar portions to the underside ‘of the ‘seat, of the legs and serve to support the tubular or adjacent to the inner and outer portions of the other narrow bar stock material against trans seat bar portions. 5 verse rocking movements whereby the securing WILLIAM R.
