Abstract

A device for releasing a mechanical energy storage device from an initial locked position in a release situation is comprised of a housing having a bearing connected thereto, a locking device for securing the energy storage device in the initial locked position and a supporting device deflectable in the release situation and connected to the bearing. The locking means is connected to the housing and rests on the supporting device in a prestressed manner in the initial locked position, whereby the supporting device is deflected in the release situation by forces created by its own inertia. The supporting device may be in the form of a spring, two springs with an inertia member therebetween, two bodies with an inertia member therebetween, or a ball in a ball socket. Another embodiment uses rollers and roller bearings.
