The deployment securing device has a first securing part which is paired with the first hinge part, a second securing part which is paired with the second hinge part, and a locking element and is configured such that the locking element is coupled to the first securing part in the closed position and is locked by the second securing part in a first locking position. The second securing part unlocks the locking element in the course of the movement of the second securing part from the closed position into the open position and thereby releases the locking element. The deployment securing device is configured such that after the locking element is unlocked in the first locking position, the locking element is moved into a second locking position in which the locking element produces a coupling between the first securing part and a third securing part paired with the first hinge part and locks the first securing part and the third securing part in the open position. ## Claims ### Claim 1 A hinge assembly for fastening a hinged cover on a vehicle body, comprising: a first hinge part, which is movable between a closed position and an open position and is intended for fastening on a vehicle body; a second hinge part, which is movable between a closed position and an open position and is intended for fastening on a hinged-cover element which is openable relative to the vehicle body; and a deployment-securing device for locking the second hinge part relative to the first hinge part, wherein the deployment-securing device comprises a first securing part, which is assigned to the first hinge part, a second securing part, which is assigned to the second hinge part, and a locking element, and is configured such that: (i) in the closed position, the locking element is coupled to the first securing part and is locked in a first locking position by the second securing part, (ii) during movement from the closed position into the open position, the second securing part releases the locking action of the locking element and frees the locking element, and (iii) following the release of the locking action in the first locking position, the locking element is moved into a second locking position, in which the locking element establishes coupling between the first securing part and a third securing part, which is assigned to the first hinge part, and locks said securing parts in the open position. ### Claim 2 (depends on 1) The hinge assembly as claimed in claim 1, wherein the first securing part of the first hinge part is part of a main link, and the third securing part of the first hinge part is part of a long link, of a four-joint hinge, and the second securing part of the second hinge part is part of an upper hinge part assigned to the four-joint hinge. ### Claim 3 (depends on 1) The hinge assembly as claimed in claim 1, wherein the locking element is a locking bolt, which is forced in the direction of the second locking position by a spring. ### Claim 4 (depends on 1) The hinge assembly as claimed in claim 1, wherein the locking element is a rotatably mounted catch, which is forced in the direction of the second locking position by a spring. ### Claim 5 (depends on 4) The hinge assembly as claimed in claim 4, wherein the spring is a helical spring or a leafspring. ### Claim 6 (depends on 1) The hinge assembly as claimed in claim 1, wherein the first securing part has a through-hole for the through-engagement of the locking element, and the third securing part has an abutment surface for abutment against the locking element. ### Claim 7 (depends on 6) The hinge assembly as claimed in claim 6, wherein the second securing part has a stop end for abutment against a stop flange of the locking element in the first locking position. ### Claim 8 (depends on 3) The hinge assembly as claimed in claim 3, wherein the spring is a helical spring or a leafspring. ### Claim 9 (depends on 1) The hinge assembly as claimed in claim 1, wherein the second securing part has a stop end for abutment against a stop flange of the locking element in the first locking position.
