Abstract

A locking device for securing at least first and second members which are movable relative to each other in response to a force acting thereon, in a locked rest position, with a release mechanism for releasing the members from their locked position, includes a locking element providing at least first and second support locations at which respective ones of the first and second mutually relatively movable members bear against the locking element to hold them in a locked condition. The co-operation of the locking element and one of the mutually relatively movable members provides a pivot axis about which the locking element is pivotable under the effect of an unlocking moment, to provide a release action. The device further includes a stationary stop means against which, in the locked position, the locking element bears due to the unlocking moment applied thereto. The first and second members, in the locked position thereof, and the locking element, combine to form a motion unit which is movable under the effect of an external force acting thereon, away from the stop means, at least to such an extent that locking element is released from the stop means. The locking device can be inco…
