Abstract (en)
[origin: EP2227988A2] The spring element has a spring body for elastically supporting a head plate (2) with respect to a base, where the head part has a central part (4) and two external parts (5). Connecting parts (6) e.g. bars, connect the external parts with the central part such that the external parts are lowered with respect to the central part perpendicular to a plane of the head plate. Springs support the external parts at the base, where the external parts are associated with the connecting parts. The connecting parts are symmetrically arranged.
