Abstract (en)
[origin: EP0933046A2] The rear section of the backrest support (6) is swiveled with an attached backrest up until the unstressed state by a spring mechanism (2.1) which has a manually adjustable spring under the front seat area. The spring mechanism for producing different spring forces is formed as a structural kit with the fixedly installed spring (2.1) and different tension springs (9) which on one side hang on the backrest support underneath the first rotary axis (5.4) and on the other side hang on a point of the bearing block (5.1) which lies behind the first rotary axis.
