摘要

The spring (10) comprises two spring elements (11,12) of which at least one has a non-linear characteristic. The spring elements are connected in series and interconnected for the transmission of tensile and compressive forces. The assembled springs have a force-travel characteristic with a rising first characteristic end section with a first spring rating up to a maximum, and a falling second end section with a second spring rating. Independent claims are also included for the following: (A) a spring element which is formed by a band spring, whereby a first spring element is riveted to a second spring element; (B) a use for the aforesaid spring which is in an operating or adjusting device with stable neutral or end positions; and (C) a spring system with two springs with steeping falling spring characteristics.
