Patent ID: 7204527

Claim:
A lock, especially for vehicles, for locking a movable part such as a pivoting door ( 41 ) to a stationary part such as a housing ( 42 ), the lock comprising: at least one longitudinally movable locking bar ( 11 , 12 ), which is driven by a rotor ( 20 ); where the locking bar ( 11 , 12 ) has a flexible inner section ( 15 ) and a rigid outer remaining section ( 14 ); the rotor ( 20 ) having a circumferential point ( 21 , 22 ) that engages a lateral flank of the flexing section ( 15 ) of the locking bar ( 11 , 12 ); a locking opening ( 43 ) in the stationary part ( 42 ), into which an outer end ( 13 ) of the remaining section ( 14 ) travels to produce a locking effect; longitudinal guide ( 31 , 32 ) for the locking bar ( 11 , 12 ), the longitudinal guide being configured to deform the flexible section ( 15 ) of the locking bar ( 11 , 12 ) during longitudinal movement of the bar, the longitudinal guide ( 31 , 32 ) having a first, curved course ( 55 ) essentially coaxial to the axis of rotation ( 23 ) of the rotor ( 20 ), and a linear second course ( 57 ) extending from and running tangential to the curvature of the first course, wherein the first course ( 55 ) accommodates the flexible section ( 15 ) and forms the flexible section ( 15 ) into a ring segment that is coaxial to the axis of rotation ( 23 ) of the rotor ( 20 ), and the second course ( 57 ) stretches and stiffens the flexible section ( 15 ) in order to transfer a force load from the rotor ( 20 ) to the remaining section ( 14 ) of the locking bar ( 11 , 12 ).
