Locking device for a vehicle seat

A locking device, particularly for a vehicle seat, for the detachable locking of two components that can be displaced relative to each other, includes a first locking element that is supported on the first component in a displaceable, particularly a pivoting manner about a first bearing pin and a second locking element that is associated with the second component and that interacts with the first locking element in a locked state of the locking device. A first safety element, that can be displaced relative to the first locking element, secures the locked state of the locking device in the normal case by acting on the first locking element. A second safety element is provided that can be displaced relative to the first locking element. The safety element supports the first locking element at least in the case of a crash. At least one spring applies a force (K) to at least one of the two safety elements, which is supported on a second bearing pin pivotally about the center (Z) thereof, at a point (P) and pretensions the element against the first locking element or against a stop. The force (K) travels through the center (Z) in at least an angular position of the safety element acted on by the spring.
