Definitions

  • the present invention relates to a chair for accommodating a person. Furthermore, a pressure device for applying local or point pressure to one or more pressure points on the human body is described, which can be used on the chair.
  • a sun deck chair is known with a tubular frame to which a seat approximately in the shape of a bicycle saddle is attached, wherein a section consisting of two parallel tubes connected in a U-shape at the outer end and pointing obliquely upwards from the seat at an angle of approximately 45° carries an armrest that can be moved along the parallel tubes.
  • each of the following office chairs is known: its backrest has a narrow upper section and a wider lower section that extends laterally in the form of wings.
