Patent ID: 8066106

Claim:
An oscillation damper for a hand-held power tool ( 2 ), comprising a damping mass ( 3 ); two first springs ( 4 ) arranged mirror-symmetrically relative to each other for axially compressively preloading the damping mass ( 3 ) against a power tool housing; at least one second, additional spring ( 9 ) for axially compressively preloading the damping mass ( 3 ) against the power tool housing; and user-operated switching means ( 8 ) displaceable between a first position in which the damping mass ( 3 ) is axially compressively preloaded against the power tool housing only by the two first springs ( 4 ), and a second position in which the switching means ( 8 ) connects the damping mass ( 3 ) with the at least one second additional spring ( 9 ) so that the damping mass ( 3 ) is axially compressively preloaded against the power tool housing by the two first springs ( 4 ) and the at least one second, additional spring ( 9 ).
