Abstract (en)
[origin: US4848837A] A chair has a spring rocker which is articulatad to a seat support at a front edge of the seat. The rocker is connected to a pelvis-hip support by a horizontal pivot device. An entrance section of the pelvis-hip support is longer than an exit section thereof. Synchronizing levers connect the seat support and the pelvis-hip support in such a way that pivoting of the seat results in a relatively greater pivoting of the pelvis-hip support. A backrest is pivotably connected to the exit section of the pelvis-hip support toward the rear against the force of a spring by movement of the body of a seated person. This permits the shell elements of the shell contour of the chair to conform better to the course of movement executed by the body, of the seated person, and to give support throughout the pelvis-hip region of the body of the seated person.
