Patent ID: RE40760

Claim:
A regulator ( 27 ) automatically controlling length adjustment of a cable ( 3 , 4 , 15 ) to drive a vehicle brake by means of a drive element, said regulator ( 27 ) comprising: first and second pivotally supported resetting arms ( 1 , 9 ) biased by at least one spring element ( 13 ) and having a common pivot axis ( 19 ), each resetting arm ( 1 , 9 ) being connectable to the cable said second resetting arm ( 9 ) comprising a radially inwardly facing abutment surface; a blocking means ( 28 ) for at least one of snap fitting and friction fitting engagement with said abutment surface and for blocking relative pivoting motion of the resetting arms ( 1 , 9 ) upon actuation of said drive element; wherein the blocking means ( 28 ) is displaceable in a radial direction relative to said pivot axis between a blocking and an unblocking position and wherein said blocking means is disposed on said first resetting arm ( 1 ) to rotate with said first resetting arm; wherein the blocking means in the blocking position automatically stops a relative pivoting motion of the resetting arms; wherein the blocking means in the unblocking position automatically permits a relative pivoting motion of the resetting arms in both directions of rotation about said pivot axis.
