Definitions

• the invention relates to a split, in particular two-part, tailgate according to the features of the preamble of claim 1 and a method for opening such a flap according to the features of the preamble of claim 10.
• 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 because only the lower part of the tailgate or the load compartment lid must be opened for loading small objects.
• 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.
• an actuating button is pressed on a button bar above the license plate. If the entire tailgate to pivot, a second locking means is activated via a second button, while the lock between the upper part of the flap and the body 7 is released.
• the operator must therefore press two buttons one behind the other to operate the large flap. This is particularly disadvantageous if the Operator is restricted in his freedom of movement, for example, because he holds a lot of luggage in his hands.
• the present invention seeks to provide a divided, in particular two-part, tailgate with locking devices for a first and second open position and a method that ensure a simple opening mechanism for the operator.
• the basic idea of the invention is the opening of the entire tailgate via a so-called push movement starting from the first open position of the cargo compartment lid. This push movement initiates the movement of the flap from the first to the second open position, which then automatically expires.
• a suitable opening element This may for example be a preloaded spring, such as a coil spring, which relaxes during the opening process. It may also be a cable, wherein the end of the cable is rolled up as a winch and the up or unwinding is accomplished by a suitable - in particular electrical - actuator.
• the cable can also be a Bowden cable.
• the transfer of the flap in the second open position (opening the entire flap) is carried out for the operator very easily by means of a push movement, which is exerted on the lower part of the flap.
• the operator only has to press against the lower part of the flap and the entire flap opens.
• This is realized via a transmission ⁇ "' 1 ' 10 '' 1 * inchocnnH ⁇ ro ° i" ° UQKQI H Qr transmits the pressure force on a contact element or a button on the body.
• the button transmits this pulse to the first coupling or locking device between the upper part of the flap and the body.
• the upper tailgate section is also unlocked, and the entire flap opens.
• opening the lower part of the flap which can also be referred to as a small flap or load compartment flap
• a small flap or load compartment flap When opening the lower part of the flap, which can also be referred to as a small flap or load compartment flap, can be unlocked immediately and only a simple push movement, the upper part of the tailgate and thus the entire flap open. It provides a simple and intuitive opening mechanism. The operator only has to operate a key at the beginning, for example above the number plate, and the opening then takes place according to the system "push to open.” The operation of the key could also be achieved by a key lock by operating a key
• a variant can be realized in which the entire flap with the lower and upper flap part arranged opposite one another is in the second open position then the entire flap is moved via the push movement.
• FIG. 1 is a side view of a two-part tailgate according to the invention in a closed position.
• FIG. 2 shows a side view of the tailgate according to FIG. 1 with an opened lower part of the tailgate;
• FIG. Fig. 3 is a side view of the tailgate, wherein on the lower part of
• FIG. 4 is a side view of the tailgate in the movement to open the entire flap;
• Fig. 5 is a side view of the fully opened flap before the final closing operation;
• 6 is a detail view of FIG. 1 for illustrating the foot contour of
• Fig. 1 shows the initial state of a two-part tailgate 1.
• the entire tailgate 1 has an upper part 2 or a large part. This is pivotally mounted on the body 3 or the side part on an axle 4.
• the opening movement is effected by means of a gas strut 5, which is preferably provided in each case on both sides of the upper flap part 2.
• the upper part 2 of the tailgate is connected to the body 3 by means of a first coupling device 6.
• the door hinge 9 of the lower part 10 of the flap (or the small tailgate part or the load compartment flap) is pivotally attached via a further axis 11 on the upper tailgate part 2 by means of a short pivot bracket 12 and thus forms a second coupling device 13 including the transmission and described below stop element.
• the lower tailgate part 10 has a lock 14, which engages in a bracket 15 on the lock carrier 16, which is arranged on the body 3.
• a stop element 17 This is formed according to the embodiment shown as a further circular bracket 18 having a projection 19 at its open end.
• a transmission element 20 preferably a lever 21, arranged with two ends 22, 23.
• This lever 21 is designed so that one end 22 can come into operative connection with a contact element 24, preferably a button 25 on the body.
• the button 25 controls the adjacent lock 7.
• the other end 23 of the lever 21 can engage with the projection 19 of the bracket 18.
• a blocking element 26 which has at its foot a contour adapted to the circular contour of the bracket 18 contour (see Fig. 6).
• This blocking element 26, preferably formed as a pawl 27, is movable upwardly along the downwardly bent end portion 28 of the upper flap 2.
• the pawl 27 is biased by means of a tensioning element, for example by means of a spring (not shown).
• the element 26 blocks the individual positions of the flaps, so that the folding angle - at least in one direction - is not changeable. If the lock is unlocked, the spring force is affected, so that the pawl 27 is pressed either independently or by sliding past the stop element 17 upwards.
• the lower flap can pivot into the first open position (angle ⁇ , FIG. 29).
• an end 29 of an opening member 30 is arranged on the projection 19 of the bracket 18, an end 29 of an opening member 30 is arranged.
• the other end 31 is located away from the coupling device 13 on the body 3 below the upper part 2 of the flap. It has here a winch 32.
• the opening element 30 is designed as a cable 33.
• the lock 14 is unlocked on the bracket 15 of the lock carrier 16.
• the pawl 27 is released.
• the cable 33 which is unrolled, the lower flap part 10 is opened and pivots upwards.
• the self-opening of the small flap 10 can be, for example, with an integral roalicoron without irhio Movement of the lower flap portion 10 and thus of the stop 19, the pawl 27 is pushed upwards and thus a blockage of the lower and upper flap parts (10, 2) to each other canceled.
• the opening angle of the flap 10 in its first open position is determined by the fact that the projection 19 of the bracket 18 abuts against the second end 23 of the lever 21. In this way, a rotation stop is formed.
• a compressive force F 0 is now applied to the open lower tailgate 10. It thereby moves to the dashed position.
• the first end 22 of the lever 21, which is close to the key 25, is pressed onto the key 25 by this push movement. It is given a signal to the lock 7 and this unlocked.
• the bracket 8 is released.
• the gas spring 5 now also the upper part 2 of the tailgate opens in the direction of the second opening position (see Fig .. 4).
• the movement of the upper part 2 of the flap is stopped by the extended gas spring 5. In this position, the winch 31 holds the cable or the rope.
• the lower flap returns to the first position due to the upward movement of the upper tailgate portion and due to the action of the gas spring 5 back.
• the two flaps 2, 10 are moved at an angle a, which corresponds to the angle in the closed state (see Fig .. 5).
• the stop 19 is moved past the pawl 27.
• this is moved back to the starting position to cause a blockage between the upper and lower flap part.
• FIG. 6 a detail of FIG. 1 is shown, after which the contour of the blocking element 26 or the pawl ° 7 ° " H! ⁇ 1 ⁇ -" + "- ⁇ - ⁇ ⁇ ⁇ I , I ⁇ " ⁇ [+ ⁇ 17, in particular to the contour of the projection 19 of the bracket 18 is adapted to ensure a slide past.
• the pawl 27 has a foot contour with a slope 34 on the side facing the lower tailgate part. Supported by this contour, the projection 19 can slide past the pawl 27. Once the projection has passed the pawl 27, the pawl 27 springs back into its blocking position.
