Locking device for functions which can be carried out in particular on vehicles

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).
