Embodiment Construction

[0049] Figure 1a A perspective view showing a first modification of the seating device 1 . The seating device 1 is designed as an office chair 1 , although it will be appreciated that the seating device is applicable to any body support structure including, for example and without limitation, other seating structures such as benches, car seats, airplane seats, and the like. The seating arrangement 1 basically consists of a substructure 3 and a seat part 4 . The substructure 3 includes casters 5 and a pneumatic buffer 6, and the seating part 4 is fastened on the head plate 17 of the pneumatic buffer (see Figure 1b ). The seat 4 basically comprises two carrying arms 7 , 8 with a body support structure, indicated for example as a seat housing 9 , forming a seat surface 10 and a backrest 11 . Two transverse carriers 12 , 13 extend between the two carrier frames 7 , 8 . The carrying arms 7 , 8 basically each comprise a first upper carrier 7 a , 8 a , a second lower carrier 7 b...

Background technique [0002] DE4433663A1 discloses a seat with seat panels superimposed on one another, the upper seat panel being supported relative to the lower seat panel at the level of the lumbar spine by means of flexural elastic plates. Since the seat panel acts like a flat spring assembly, this seat reacts very sensitively to the upper part of the body, tending to recline resiliently as the individual leans back in the seat. Due to this construction, the substructure of the seat is subject to large loads and must be dimensioned accordingly. [0003] US6986549B2 discloses a seat with a backrest that reacts to forces acting on it by changing its shape. This backrest is formed by two surfaces called shells and has a plurality of hinges, the opposing hinges of the two shells are each connected by individual ribs. Due to its specific structure, this backrest tries t...
