Definitions

  • the present invention relates to a connection arrangement for or in a chair, in particular conference or office chair, a method for producing such a connection arrangement and a chair with such a connection arrangement.
  • Office swivel chairs usually have a swivel mechanism and an armrest. There are a variety of configurations of swivel mechanisms, armrests and their connection.
  • An armrest carrier is typically attached to a seat carrier.
  • a chair and such an armrest carrier are for example in the DE 10 2008 042 974 B3 described.
  • the base and handlebars of a swivel mechanism of this office swivel chair are designed to be relatively solid and have a return spring integrated in the swivel mechanism. Overall, therefore, a relatively large space is needed. Furthermore, the entire structure of such office swivel chair is very massive, which increases the weight and is particularly disadvantageous in design aspects.
  • the present invention seeks to provide an improved connection arrangement for a chair.

  • connection assembly according to the invention is very easy and inexpensive to assemble.
  • the bearing pin can also be fixed in such a way in the armrest carrier, in particular on a side facing the backrest support, that it is invisible from the outside. For example, it can be admitted to the production on the backrest support side facing or partially sunk in a blind hole.
  • connection arrangement according to the invention has a particularly small installation space.
  • the bearing pin can be fixed in a narrow cross-section of the armrest carrier.
  • a height of the cross section may be less than five times a core diameter of the bearing pin. In this way, a particularly slim design of a armrest carrier is possible.
