Claim:
A lock device for functions that can be performed in vehicles, comprising: a lock cylinder ( 10 ), which consists of a free-turning sleeve ( 11 ) and a cylinder core ( 12 ) with tumblers ( 17 ), the core being rotatably supported in the sleeve; a key which fits the cylinder core ( 12 ) and which, in a normal case ( 43 ) when inserted, controls the tumblers ( 17 ), and, after the key is removed, the tumblers ( 17 ) lock the cylinder core ( 12 ) to the free-turning sleeve ( 11 ); a stationary housing ( 18 ) for rotatably supporting the free-turning sleeve ( 11 ), an output element ( 19 ), which is rotatably supported in the housing ( 18 ) and performs the functions in the vehicle by its rotation; a prefabricated component ( 30 ) made up of two functionally different sections ( 31 , 32 ), one section being a nondeformable pin ( 31 ) and another section being a flexible element ( 32 ); the component ( 30 ) being handleable as a whole and forming an insert in the housing ( 18 ); the housing ( 18 ) having an axially open chamber ( 25 ) laterally adjacent the free-turning sleeve ( 11 ), the component ( 30 ) being insertable into an interior of the chamber ( 25 ) via a chamber opening, the flexible element ( 32 ) of the component ( 30 ) being supported on an inner wall ( 26 ) of the chamber ( 25 ), while the pin ( 31 ) is under spring tension ( 34 ) radially against the free-turning sleeve ( 11 ); the pin ( 31 ) being radially movable in the housing ( 18 ) and in the normal case ( 43 ) rotationally holds the free-turning sleeve ( 11 ) in the housing ( 18 ) but releases the free-turning sleeve ( 11 ) in an overload case ( 44 ) in which the cylinder core ( 12 ) is forcibly turned; a coupling element ( 20 ) that at least partially covers the axial opening of the chamber ( 25 ) so as to secure the inserted portion of the component ( 30 ) in the chamber ( 25 ) of the housing ( 18 ); wherein the coupling element ( 20 ) is radially slideable relative to the cylinder core. ( 12 ) and is coupled with the cylinder core ( 12 ) in the normal case ( 43 ) of the free-turning sleeve ( 11 ), and is uncoupled in the overload case ( 44 ); the coupling element ( 20 ) being nonrotatably connected to the output element ( 19 ); wherein an axial connection ( 33 ) between the coupling element ( 20 ) and the pin ( 31 ) of the component ( 30 ) provides a joint radial movement of the pin ( 31 ) with the coupling element ( 20 ); and wherein the radial spring tension ( 34 ) of the element ( 32 ) of the component ( 30 ) simultaneously generates a radial restorin force of the coupling element ( 20 ) via the connection ( 33 ).
