One end (52) of the spring is secured to the seat section and the other end (48) to a flexible connector (40) such as a belt, chain or cable running over a pulley wheel (44) and attached to the guide post by an end (42). ADVANTAGE - Seat having good springing behaviour in which the load between the guide post and the seat section is almost inversely proportional to the load.
