Seat Furniture, More Especially Office Swivel Chair

Abstract

Seat furniture is provided that includes a seat and a backrest support which are mounted on a support member, the backrest support being pivotal about a horizontal pivot axis, and an energy accumulator which is tensioned when the seat is subjected to a load and acts on the backrest support, the energy accumulator engaging the backrest support at an effective distance from the pivot axis, characterized in that the energy accumulator is connected on one side to the support member and on another side via a transverse connector to the backrest support.

1 . Seat furniture comprising a seat and a backrest support which are mounted on a support member, the backrest support being pivotal about a horizontal pivot axis, and an energy accumulator which is tensioned when the seat is subjected to a load and acts on the backrest support, the energy accumulator engaging the backrest support at an effective distance from the pivot axis, characterized in that the energy accumulator is connected on one side to the support member and on another side via a transverse connector to the backrest support.
