I cum (Cl. 155-53) This invention relates to a new and improved type of chair or the like having a spring-suspended seat frame which is pivoted at its forward part. The object of theinvention is, by a special arrangementof the springing of the seat frame in combination with the special construction of the back, to provide seating means capable of unusually perfect adaptation to the shape of the body in thesitting posture, and also of being so constructed for incorporation in vehicles that shocks and jolts incurred in a vertical'direction are particularly well absorbed and converted intogentle rocking movements.

In accordance with the invention the seat frame is suspended 'on elastic tensile members attached by one end tothe rear portion of the said frame and by the other end to the top of the counter-support for the back of the chair or other sitting means. These tensile members, in

the form of helical springs, rubber cords, or the like, which permit of the elastic yielding of the seat proper, are themselves capable of yielding both towards the rear and laterally when the seat is weighted, and are thus capable of adapting themselves exactly to the shape of the sittln8 body. Inthisrespect thechair orthelike according to the invention behaves like a hammock, the essential difference being that in the present instance the yielding elements are also capable of being stretched longitudinally. This universal resilient yielding action can be still further increased if the principle. of the invention be applied to a chair made of steel tubing, and the tensile members be attached by their 35 upper ends to a non-supported and therefore itself resilient portion of the framework. In thecase of seats for use in vehicles. the rear portion of the seat frame can be connected by means of further elastic tensile members or of extensions of those already described to a portion of the -framework situated at a lower level or to the floor. thus providing the advantage of pre-tensioning these members.

Three examples of forms of construction embodvins the invention are illustrated in the accompanying drawing, in which:

Fig. 1 shows an armchair in accordance with the invention, having a wooden framework.

Fig. 2 shows a steel tube chair made in accordance with the invention.

Fig. 3 shows a seat designed for incorporation in a vehicle. 7.

tensile members in the form of construc- Throughout the drawing denoted by the same reference characters.

Referring to the drawing, a denotes the framethe same parts are work of the chair or the like, I) the seat frame pivoted in front, and d the transverse member 1 of the framework of the back. Tension springs e (Figs. 1 and 2) connect the-rear portion of the seat frameto the transverse framework member d, and thus extend over the entire height of the back. In this manner these springs are rendered readily capable of yielding and of adapting themselves to the shape of the body. These springs thus fulfill the dual functions of a resilient suspending means for the seat and of an unusually resilient and adaptable back to the chair or.the like. .In the" arm chair shown in Fig. 2 the parts a and d consist'in the usual manner of a single pieceof steel tubing, so that the springing of the seat frame and of the back support is supplemented'by the inherent resilience of the portion 41 of the framework. The ends of. the springs are formed into loops which are suspended in hooks in conjunction with the parts I: and d.

The vehicle seat shown inFigs. 3 and 4 has a wooden framework :1 with a frame 1 adapted to stand on the floor. On the rear member of the seat frame there are provided sheetmetal fittings 9 having perforated wing portions extending upwards and downwards. Into the upper of these lower ends of the ,above 'described springs e,

while the lower perforations are engaged by the shock or jolt incurred by the vehicle produce.

additional tension alternately in each of the two groups of springs, and are thus rapidly and yet elastically absorbed. The lowerends of the springs e can if desired be attached to any other fixed object, for example directly to the floor of the vehicle. The springs can also be attached directly to the seat frame, being suspended for example from a rod It, passed through eyelets k on the seat frame (see Fig. 4).

I claim: In an easy chair or the like, a main frame, a

in the position of rest. I

perforations there are suspended the seat frame pivoted thereto at the front, said main frame having a rear support above said seat frame, and a back rest comprising a pluralityiof coil springs suspending the back of said seat frame from said rear support, said coil springs forming back of a person sitting in the chair.
