Device for manually unlocking a holding mechanism to which a load can be applied

An unlocking device for unlocking a holding arm, the unlocking device comprising:

• a housing;
• an operating element which can be operated manually for unlocking the holding arm via an operating force,
• a conversion mechanism which includes a force transfer element operatively coupled to the operating element for movement by the operating element,
• a trigger coupled to the force transfer element and moveable with respect to the a housing, wherein the trigger is movable by the operating force transferred by the force transfer element to the trigger from (i) a locked position in which the trigger does not displace an unlocking component, to (ii) an unlocked position in which the trigger presses the unlocking component and holds the unlocking component in a displaced position,
• wherein the conversion mechanism includes an elastically deformable force limiter via which the force transfer element is operatively coupled to the trigger and which limits, due to the elastic deformation thereof, a transfer of the operating force from the operating element to the trigger, if the operating force exceeds a predetermined force, and
• an end stop, the end stop positioned for limiting elastic deformation of the force limiter,
• wherein the end stop is formed by an end stop surface that abuts the force transfer element.

An unlocking device for unlocking a holding arm, the unlocking device comprising:

• a housing,
• a handle which is manually movable for unlocking the holding arm, the handle comprising a pressing surface,
• a force transfer element operatively coupled to the handle,
• a trigger coupled to the force transfer element,
• an elastically deformable force limiter via which the force transfer element is coupled to the trigger, and
• a conversion mechanism, the conversion mechanism comprising the force transfer element and a toggle lever having a first leg and a second leg,
• wherein the first leg of the toggle lever is rotatably supported at a first end in a first center of rotation inside the housing,
• wherein the second leg of the toggle lever is rotatably supported at a first end in a second center of rotation,
• wherein the first leg and the second leg are rotatably supported at respective second ends at a common third center of rotation,
• wherein during manual operation of the handle the pressing surface presses onto the toggle lever in a region of the third center of rotation to actuate the force transfer element, and
• wherein the trigger is movable by an operating force transferred by the force transfer element to the trigger from (i) a locked position in which the trigger does not displace an unlocking component from within the housing into (ii) an unlocked position in which the trigger presses and displaces the unlocking component by pivoting the unlocking component outwardly from within the housing.
