Abstract
The invention relates to a seating assembly (100) comprising a basic frame (101), a seat unit (102), and a back-support unit (103) wherein the seat unit and the back-support unit have a common pivoting axis (P) with respect to the frame at the level of the hip joint. Hence, based on human body like biomechanics and physiognomy, the seating assembly, particularly for ergonomic chairs or wheelchairs, provides a highly improved seating comfort, even with therapeutic effect.
Claims12
A seating assembly comprising:
- a seat base unit,
- a seat unit, and
- a back-support unit,
- wherein:
- both the seat unit and the back-support unit have a common pivoting axis with respect to the seat base unit at a joint level above the seat unit;
- the seat unit and the back-support unit are connected to the seat base unit by a pair of opposed pivot points at the joint level and lying on the common pivoting axis at each side of the seating assembly;
- the seating assembly further comprises three motion control devices adapted to control a pivoting movement while connecting all of the units with each other;
- the three motion control devices comprise a first motion control device, a second motion control device, and a third motion control device, each motion control device being provided in either an open position or a locked position;
- the first motion control device is adapted to control:
- a pivoting movement of only the seat unit with respect to the seat base unit;
- and
- a pivoting movement of the seat unit and the back-support unit with respect to the seat base unit;
- the second motion control device is adapted to control:
- a pivoting movement of only the back-support unit with respect to the seat base unit;
- the third motion control device is adapted to control:
- a pivoting movement of the seat unit with respect to the seat base unit while the back-support unit is in a fixed position;
- and
- any of the pivoting movements is enabled by a force exerted on the seating assembly.
