  • the initial curvature of the flexible hammock member is a very important factor in sitting comfort. For instance, if the initial curvature of the flexible hammock member is tooK great, the support to the small of the back is considerably reduced, while if too small, the bodyangle will be unsuitable, for maximum com-f fort.
  • the necessary adjustment of the initial curvature of the iiexible hammock member is very critical as even a small variation will make a considerable difference to sitting comfort and it is therefore essential that the adjusting meansassociated with the upper anchorage should be capable of effecting small and accurate adjustments ⁇ oi' the curvature of the flexible hammock member whereby full and most comfortabler sup. port of the body of any individual person can be readily obtained and thereafter maintained if required by such further adjustment as may bel necessary to compensate for stretching which may take place in the Various materials used for making the flexible hammock member.
  • the present invention has for its object to provide an improved, simple and conveniently operable construction of seat-adjusting means whereby the initial curvature of the exible hammock member may be readily set or adjusted as required to provide maximum sitting comfort.
  • the adjusting means comprisesA a cross-bar or the like to which the upper end of the flexible hammock member is connected, said cross-bar or the like being movable in relation to the seat frame, and screw means co-operating with said cross-bar or the like for adjusting its position for tightening or slackening the flexible hammock member.
  • the said cross-.bar or thev like is mounted forV movement in an upward and down-. ward direction in, relation to4 the seat frame.
  • the invention includes a seat of the kind referred to, comprising a flexible hammock cushion, a pivoted or spring-mounted thigherest supporting the lower end portion of the cushion, and an upper anchorage in the ⁇ form of a cross-.bar or the like supporting the upper end portion of the cushion, characterised in that said cross-,bar or the like is movable in an upf ward and downward direction in relation to the. seat frame, and screw. means co-operating with the said cross-.bar crv the like. is provided for ad. justing the position of said crosssbar or the like, in relation to the seat frame.
  • the. screw means comprises an eye-.bolt or the like disposed to coact with the cross-.bar or the. like at a middle position in its length and engaging a correspondingly screwed member care ried by a cross-rail of the seat frame.
  • the upper end portion of the. ilexible hammock member is connected to and directly supported by the adjustable cross-A bar or the like.
  • a flap or extension attached to the upper end of the flexible hammock meme ber passes over a roller or bar at theV rear. upper part of the seat frame and is connected to the adjustable cross-bar or the like.
  • the crossfbar or the like may be located by guidey means so as to be slidable in relation to the seat frame.
  • Fig. 1 is a part sectional side elevation of a seat of the kind referred to provided with means in accordance with the invention for adjustingthe initial curvature of the flexible hammock cushion;
  • Fig. 2 is a detail perspective view from the rear of the adjusting means.
  • Fig. 3 is a detail sectional elevation illustrating a modication of the adjusting means shown in Figs. 1 and 2.
  • the invention is shown in its application to a seat in which a flexible hammock member in the form of a cushion l has its front end 2 connected to and supported by a pvotally or spring mounted thigh-rest 3.
  • the hammock cushion is provided near its upper end with a flap 4 sewn or otherwise fixed at a predetermined position on the back of the cushion, and this flap 4 is xed to a cross-bar 5 which is adjustable vertically in relation to the seat frame 6.
  • the cross-bar 5 may be provided near its ends with clearance holes for two guide pins I xed to and projecting upwardly from a cross-rail 8 secured between side bars of the seat frame 6. Furthermore, the ends of the cross-bar 5 or the like are tted with means, such as plates 9 projecting therefrom to slidably engage vertical side members I6 or grooves therein to take the strain o the guide pins 1 when the chair is occupied.
  • the cross-rail 8 referred to is provided with a screw device, such as an eye-bolt Il, having the eye l2 depending below the crossrail 8 and having its threaded part engaging a flanged nut i3, the flanged part of which rests on top of the cross-rail 8.
  • the upwardly projecting end of the eye-bolt l l may be burred so as to prevent inadvertent withdrawal from the nut and may bear against a dimple plate Ill fixed to the underside of the cross-bar 5 or the like.
