ABSTRACT:
An adjusting device includes a piston cylinder unit with a cylinder having a piston and a piston rod movably arranged therein, the piston rod extending out of the cylinder. A piston rod guide includes a support element having a first part arranged in the cylinder and bearing axially against one part of the cylinder and a second part connected to the first part. An annular seal arranged between the second part of the support element and the interior of the cylinder such that pressure in the cylinder acts on the seal which bears on the second part of the support element. The connection between the first and second parts of the support element is releasable when the force of the annular seal bearing on the support element exceeds a bearing force limit. The first and second parts of the support elements move telescopically from a normal position to an overload position when the connection is released and reduce the axial length of the support element. A stop supported on the first part protrudes through said second part and is proximate the annular seal in the normal position.
