Definitions

• the invention relates to a divided, in particular two-part, tailgate according to the features of the preamble of claim 1.
• Such two-part tailgates are known, for example, from EP 0 718 134 A1 and DE 44 00 374 A1.
• Such tailgates consist of an upper part, which is pivotally mounted on the body, and a lower part, which in turn is pivotally mounted on the lower edge of the upper part.
• Vehicles with such two-part tailgates have a high loading variability. With the large flap open, large and bulky objects can be admitted into the hold. If only a few or small items are to be invited, optionally only the lower part of the tailgate can be opened. This also has the advantage that persons sitting in the vehicle are less exposed to the outside temperature during the opening process. In addition, the cargo space can be opened easily in lower rooms.
• a tailgate is also known.
• a connection of the upper part of the tailgate with the body in a first open position and the other is a connection of the upper and the lower part of the tailgate in a second open position.
• a first cam which is fixed to the body, with a locking element, ie a bolt on the upper part in engagement.
• the lower part of the tailgate is unlocked and can be swiveled without the upper part of the tailgate.
• this cam is moved out of the locked position.
• a coupling member here in the form of a co-moving depression, in which a flat member dips, simultaneously a second cam is moved, which fixes the swivel bracket to which the lower part of the tailgate is attached.
• a coupling member here in the form of a co-moving depression, in which a flat member dips, simultaneously a second cam is moved, which fixes the swivel bracket to which the lower part of the tailgate is attached.
• WO 2007/062635 proposes a locking unit for a two-part tailgate, with which it is ensured that the decoupling of the lower part from the upper part of the tailgate is only canceled if already a locking of the upper part of the tailgate to the body took place in an intermediate position. In this way, a simultaneous release of the upper part of the tailgate from the lower part of the flap and the body is prevented.
• This is achieved by means of a driver or lever which is connected to the locking element. This is gripped by an actuator, locked in an intermediate position and then rotated, the locking element is opened only with the rotational movement.
• the present invention seeks to provide a split, in particular two-part, tailgate with locking devices for a first and second open position, which work effectively and effectively with low component cost.
• At least one of the locking devices as a locking element comprises a rocker-like element or a rocker which is movable between a first and second end position and effects a locking in at least one of the end positions.
• This rocker is - preferably indirectly - moved over a particular motor actuator and that of a first end position, in the means of the first locking device, the upper part of the tailgate is connected to the body, to allow the first opening position, that is, the folding of the lower part of the flap, in a second end position, in which the second locking means connects the upper and lower parts of the large tailgate while the first locking device is open.
• the two locking devices are here combined to form a unit and formed in the sense of DE 10 2006 013 735 A1 as a double mechanism.
• the rocker is pivotally mounted on the frame of the upper rear flap portion and clamped by a spring relative to the frame.
• a spring relative to the frame.
• the second locking means is provided between the frame and the suspension of the lower flap part, i. the swivel bracket, formed by a locking element which is arranged on the suspension itself. It may be a pin or a backdrop that surrounds the rocker or in which it engages. It may also be a receiving opening in the swivel bracket.
• the first locking device between the body and the frame is activated either by the rocker or a separate element. This is then a body-mounted actuator that either with a frame-fixed point or the rocker itself engbe or acts on the rocker.
• the actuating element is a body-fixed pivotable finger-like element, which forces on the one hand by contact with or on the rocker-like element against the spring force to grip a body-fixed point, thus forming the first locking device and on the other By releasing a contact surface with the rocker-like element causes it to pivot in the other direction and engages around a pin of the suspension of the lower part of the tailgate, so as to form the second locking device.
• the rocker is part of both the first and second locking device, and only a few components are required for the lock.
• the rocker-like element on a connecting pin which engages the formation of the second locking position in the swivel bracket of the lower part of the tailgate, wherein the rocker-like element has a projecting bracket, in which a body-mounted actuator is engageable, so that the rocker-like Element is pivotable in a first locking position against a spring force, in which the frame is coupled via the rocker to the body.
• the rocker-like element comprises two brackets, wherein the formation of the second locking device, the first bracket engages in a link which is arranged on the suspension, and the second bracket is designed so that it is formed upon pivoting of the actuating element the second locking position against the spring force is pivotable, with the backdrop detent triggers.
• This alternative has the advantage that the locking in the scenery is very safe and withstands stronger loads.
• the invention preferably proposes that the rocker is assigned to the locking means as a locking element as a common element which causes a locking in its respective end position, while the respective other locking device is opened.
• This variant allows a lock with a small number of components.
• the rocker is designed so that it activates both the first and the second locking device in an intermediate position. In this way, a lock while driving in the closed state of the door is possible.
