    [0001] The present invention relates to a device and / or an unlocking system for a vehicle hood, in particular for a front flap of a motor vehicle, comprising a driving element that can be actuated via a release lever connected via means Bowden cables, at least one stop hook provided in the vehicle body and pivotable, via Bowden cables can be moved by the release lever, in an unlocked position for opening the hood. Release devices for vehicle hoods are known comprising a driving element that can be actuated by a release lever connected, via a Bowden cable, to a vehicle stop hook and that can be actuated via the cable release lever. Bowden and can move the vehicle hood to an unlocked position and open the hood.
    [0002] The object of the present invention is to create an unlocking device for a vehicle hood, in particular a front cover, by means of which a separation of the positioning functions and / or the actuating forces is guaranteed during a pivoting of a release lever and / or placement of the device to unlock.
    [0003] This objective is achieved thanks to the device according to the present invention. The main advantages achieved with the present invention are to avoid the presence of excessive play and increasingly large in the unlocking system through a separation of functions in case of actuation of the unlocking system. This is achieved according to the present invention in that the drive member comprises a cylindrical bearing lug composed of an oblong bushing shank, with the release lever or the head-end connected positioning, said lug being guided so as to can be rotated in the axial plane in an oblong reduction sleeve fixedly fixed in place in a bottom plate via a bayonet catch and at which a serrated ring held at the free end of the cylindrical bearing lug is supported or supported in the axial plane with respect to, or on the side of, the reduction sleeve. This embodiment and arrangement of the components of the device makes it possible to separately absorb the transverse forces of an axial guide. The very long reduction sleeve, connected in form complementarity to the base plate by means of a bayonet connection, makes it possible to absorb the radial actuating forces F 1, introduced by the force of the hand onto the drive element at the release lever and discharge them, via the bottom plate, onto the link. The serrated ring only has to transmit the reduced axial forces F2 produced by a possible oblique traction. In particular, it is provided according to the present invention that the drive member has at the outer periphery a pot-shaped annular bushing with a receiving space for a pivoting spring element above which an annular guide slot. swivel is arranged on the head side. It is also provided according to the present invention that the reduction sleeve is disposed with an upper front end in the pivoting annular guide slot and has at the lower end section facing (or opposite) a bearing ring resting on the base plate fixed in place on the upper side and can be fixed thereto via or via the bayonet connection. This pivoting guide ring notch 20 located on the head side makes it possible on the one hand to hold the drive member in the axial plane in the annular sleeve on the pot side and, on the other hand, to guide it so as to be able to turn. It is further provided according to the present invention that the pot-shaped annular bushing of the driving member is rotatably held on the upper side, with a lower front end, on the bearing ring of the oblong reducer sleeve resting on the bottom side on the bottom plate. The annular sleeve is thus arranged on the bottom plate via the bearing ring forming, with the annular bushing, a fixed construction unit, via the link, thus making it possible to guide the driving element in a safe pivotal manner on the reduction sleeve. The bearing bushing of the oblong reduction bush meshes, in particular, with the bottom plate from above and the latter is fixedly connected in place in a position of attachment to the bottom plate via the bayonet catch. The bayonet closure comprises in known manner, on the lower side of the bearing ring, cams that can be threaded into the corresponding recesses of the bottom plate and a torsion of the bearing ring for fixed locking this last in the bottom plate. It is furthermore provided according to the present invention, for unlocking and locking the stopper hook relative to the vehicle hood, that the pivoting spring element is connected with the upper end to the driving element. in the receiving space of the pot-shaped annular bushing and is held hooked, with a remote lower end, in the bearing bushing of the reduction bushing, in a receiving opening. This arrangement and the connection of the pivoting spring element to the driving element on the one hand and to the bearing ring of the annular bushing on the other hand allow, after an unlocking movement of the release lever, to recall the latter via the spring force. An exemplary embodiment of the present invention is shown in the drawings and will be described in more detail later. Figure 1 illustrates a view of the unlocking device with locking hooks in the vehicle body, as well as caliper elements in the vehicle hood; Figure 2 illustrates a representation of the unlocking device with a release lever stopped at the drive member and Bowden cables leading to the locking hooks in the vehicle body; Figure 2a illustrates a representation of the unlocking device in an unlocked position II actuated; Figure 3 illustrates an exploded view of the release device with drive element, pivoting spring, reduction sleeve with bearing ring, bottom plate and serrated ring; Figure 3a illustrates a representation of the unlocking device with locking hooks in a non-actuated locking position; Fig. 4 illustrates a vertical section through the mounted unlocking device, with correspondingly acting F1 and F2 forces; and Fig. 5 illustrates a bottom view of the serrated ring locking device and bayonet closure. An unlocking device 1 for hooks 2 of a vehicle hood H is actuated via an unlocking lever 3 or a positioning lever pivotally attached to a driving element 4 via a 5. The stop hooks 2 are connected to the driving element 4 via the Bowden cables 6, 7, said hooks being able to be moved to an unlocking position II by means of the unlocking lever 3. this position II, the stirrup elements B or their equivalent are released in the vehicle cover H, for tilting said cover upwards in an open position. The stirrup elements B are again meshed from behind by the stop hooks 2 to allow locking when the vehicle hood H is closed.
    [0004] The drive element 4 essentially comprises a cylindrical bearing lug 9 consisting of an oblong bushing shaft 8 which is rotatably guided in the axial plane in an oblong reduction sleeve 11 fixedly held in place. against a bottom plate 10. A serrated ring 14 is attached to the opposite lower end 12 of the socket rod 8, said ring pressing, on the front side, in the axial plane (or axially), against the end The driving element 4 has on its outer side an annular tubular socket 16 having a receiving space 17 for a spring element 18. A pivotable guide groove 20 provided for the driving element 4 is disposed in the head 19 of the annular bushing 16. The annular bushing 16 is arranged to enter the notch 20 with a front end 21, the driving element 4 being guided so as to be rotatable in said slot. At the lower end section, the reduction sleeve 11 has the bearing ring 23 resting on the bottom plate 10 on the upper side and fastened to it via a bayonet connection 24. The socket The annulus 16 in the form of a pot is held on the bearing ring 23 so as to be rotatable with the lower front end 21a, said ring resting on the lower side on the bottom plate 10. The bearing ring 23 of the The reduction sleeve 11 engages the bottom plate 10 from above and is secured to the bottom plate 10 in a fastening position via the bayonet connection 24. The pivotal spring element 18 is connected with a top end 25, to the driving element 4 in the receiving space 17 of the annular sleeve 16 in the form of a pot and is kept hooked, with a remote lower end 26, in a receiving opening provided in the bearing ring 23 of the reduction sleeve 11. In the situation of actuation of the release lever 3 in the direction of the arrow P (FIG. 2) with the force F1 (FIG. 4), the drive element 5 4 turns against the tension of the spring element 18 in the oblong reduction sleeve 11; this activates the Bowden cables 6, 7, thus unlocking the stop hook 2 respectively with respect to the stirrup element B in the vehicle hood H. The stops 27, 28 on the bottom plate 10 limit the ability of tilting of the drive element 4 in both directions. After release of the release lever 3, the latter tilts via the spring element 18 to resume its starting position I. The reduced axial forces F2 (FIG. 4) appearing during a possible oblique traction during actuation are transmitted by the serrated ring 14 to the fixed reduction sleeve 11 on the spot and / or 15 absorbed by it. Of course, the invention is not limited to the embodiments described and shown in the accompanying drawings. Modifications are possible, especially from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing as much from the field of protection of the invention.
