Abstract
A body support structure, such as a piece of furniture, in particular a piece of furniture for sitting on or a piece of furniture for lying on, such as, for example, chair, armchair, stool, bed or sofa, a seat of the piece of furniture being supported by a spring mechanism, and the spring mechanism being capable of being set to a weight force with which a person acts on the seat.
Claims21
A body support structure comprising:
- a spring mechanism operable to support a body support member;
- a weighing mechanism comprising a height adjustment device, an axial bearing coupled to the height adjustment device and a spring element supporting the axial bearing, wherein the height adjustment device is moveable against the biasing force of the spring element in response to an application of a body force to the body support member independent of a height adjustment of the height adjustment device;
- and
- a movement converter coupled between the weighing mechanism and the spring mechanism, wherein a biasing force of the spring mechanism is adjustable in response to a movement of the height adjustment device against the biasing force of the spring element.
