Abstract
A springing arrangement comprises a coil spring and a spring-engaging member acting thereon between the two ends of the spring and in a direction which differs from the longitudinal direction of the spring, thereby to provide non-linear dependency of the spring force on the distance covered by the spring-engaging member. The spring-engaging member is made up of two elements on respective sides of the spring, each element bearing against the spring by way of a curved surface and extending over a plurality of turns of the coil spring.
