Abstract

Spring arrangement for mounting a vibration- or shock-sensitive device attached to a supporting member in a housing, with the supporting member being fastened to the housing by helical spring elements. The supporting member is suspended in the housing by helical spring elements so that each elastic force component of one spring applied to the supporting member in a specific direction is counteracted by at least one elastic force component of another spring applied in the opposite direction so that the supporting member remains approximately in the center of the vibration clearance provided regardless of the position in which the housing is mounted in a motor vehicle. Due to the opposing elastic forces of the springs, the spring constant and therefore the natural frequency of the overall system can be advantageously increased, thus avoiding undesired points of resonance at low frequencies.
