Between the backrest support plate and the support backrest there is at least one spring for biasly a seat support bracket, with one end of the spring being able to be moved in relation to the backrest support plate (or the backrest support) by an adjustment member which adjusts to different weights. More specifically, this end of the spring is connected to a support lever which may be rotated about a generally horizontal axis and is fixed to the backrest support, while the other end of the spring is acted upon by an adjustment lever which may be spring-locked in a number of different positions for keeping the support lever in different positions of adjustment. The adjustment lever is also rotatably fixed to the backrest support.
