1 and 2, a lock device 1 for an opening one and lockable hood or flap of a motor vehicle not to be seen here described. The lock device 1 has, for example, a lock that is closed on all sides Lock housing 2, which has only one opening 3, from which a main catch protruding bolt 4 protrudes, which is part of an otherwise not shown here Locking mechanism is. The bolt 4 is movably mounted in the lock housing 2. In In a movement position, it encompasses one shown in FIG. 2 as the main catch Closing element 5, which is implemented, for example, as a striker and not on the shown hood is attached. In another movement position, the latch 4 this closing element 5 free so that the hood can be opened. The latch is on can be controlled manually, for example, mechanically or via a drive device AE.

The lock device 1 also has a catch hook module 6, which has a catch hook 7, which forms a so-called preliminary catch and the closing element 5 in the partially open position the hood partially encompasses when the closing element 5 is already from the Main catch (bolt 4) is released. The catch hook 7 is in the basic or Preliminary locking position VP. In the exemplary embodiment shown, the catch hook 7 is manual can be operated and can thus from the pre-locking position VP in the release position for the Closing element 5 are brought in that the hood is opened completely by hand can be.

The catch hook module 6 comprises an essentially flat carrier plate 8 on which the Catch hook 7 in a possibly non-detachable pivot axis, for example realized as a rivet 9 is connected to the carrier plate 8. A return spring 10 for the catch hook 7 engages with one end 11 on the carrier plate 8 and with its other end 12 on the Catch hook 7, whereby this in its pre-locking position VP shown in Fig. 1 is held or swung back there. For fastening the return spring 10 are protruding both on the carrier plate 8 and on the catch hook 7 Fastening tabs 13 are provided, on which the return spring with its ends 11 and 12 is mounted. For the actuation of the catch hook 7, this is approximately forked or U-shaped. realized in form, with the hook 14 at one fork end and the other Fork end an actuating handle 15 is designed for manual actuation. At his The base is the fork-shaped catch hook 7 via the pivot axis 9 with the carrier plate 8 connected.

The carrier plate 8 is essentially rectangular and has an after downward extension 16 (Fig. 3) which carries the pivot axis 9. In the Rectangular support plate 8 is - approximately opposite the extension 16 - in the middle Cutout 17 introduced to the U-shaped opening 3 in the lock housing is adapted so that the closing element 5 can cooperate with the bolt 4. In addition, 8 engaging elements 18 are formed on the carrier plate, which are spaced apart to each other and for example in the corners of the rectangular support plate 8 are arranged. The engaging elements 18 are realized as sleeves 19 and with one fitted at the end of the collar 20, which on the side 21 of the carrier plate 8 lies which side 21 is facing away from the lock housing 2. The other side 22 of the Carrier plate 8 therefore rests on the lock housing 2 when the catch hook module 6 is attached to the lock housing 2, as can be seen from FIG. 3. They are at the Carrier plate 8 provided engagement elements 18 in on the lock housing 2nd provided receptacles 23 inserted, the lock housing 2 parallel to Push through pivot axis 9. The recordings 23 can each of a rotating Wall 24 may be limited, which form a housing section of the lock housing 2, so that the lock housing 2 is closed. Both the sleeves 19 and Engagement elements 18 and the receptacles 23 preferably have one circular cross-section, the outer diameter of the sleeves 19 being less than the inner diameter of the cylindrical receptacles 23. The wall 24 thus forms one Pipe jacket as the housing wall section of the lock housing 2.

For the attachment of the catch hook module 6 on the lock housing 2 are in the Fig. 3 not visible lock housing side fasteners, for example Screws inserted in the receptacles 23 and on the in the receptacles 23 protruding engagement elements 18 set. The sleeves 19 can accordingly Have internal thread. The carrier plate 8 can thus with the articulated thereon Catch hook 7 fixed, but releasably connected to the lock housing 2, each after whether the lock device 1 is used for rear or front hoods should.

So that the catch hook 7 when pivoting about its axis 9 not on the collar 20 of the hits sleeve 19 lying adjacent to the swivel angle range α, is the swivel axis 9 between catch hook 7 and carrier plate 8 surrounded by a spacer 25, the for example as a ring element or through several ring segments and possibly in one piece is made with the support plate 8. The strength of the spacer 25 is greater or equal to the height HE of the collar 20.

To limit the swivel angle α of the hook 7 is on the Catch hook module 6 arranged a swivel angle limiting device 26, the one bent swivel angle limit stop 26 'on the catch hook 7 and one Control path 27 which is formed by an opening in the support plate 8 can. Alternatively, it is conceivable that the swivel angle limitation of the catch hook 7 by the collar 20 of the sleeve 19 or a lying adjacent to the catch hook 7 on the support plate 8 lying projection is realized. Possibly. could then on that Distance means 25 between catch hook 7 and support plate 8 can be dispensed with.

The detachable fastening of the catch hook module 6 to the lock housing 2 can the lock device 1 can be used both for motor vehicle hoods, the one Catch hook 7 need or where it can be dispensed with. At am Lock housing 2 attached catch hook module 6 is this through the engaging elements 18 and the associated receptacles 23 are aligned in the correct position in relation to the bolt 4, so that adjustment work can be dispensed with.
