Closing device for a motor vehicle

Abstract

A closing device for a motor vehicle includes a locking mechanism having a rotary latch and at least one pawl, a trigger lever, with the locking mechanism being unlocked by the trigger lever, and a blocking component which is arranged on the closing device for blocking a movement of the trigger lever when a load acts on the motor vehicle from the outside. The blocking component can be guided in the closing device in a movable manner.

Description

(1) The following are shown:

(2) FIG. 1 a three-dimensional view of a closing device and, particularly of the lock plate with a blocking means in an initial position,

(3) FIG. 2 a further three-dimensional view of a closing device, whereby the lock lid for illustrating the contact surface for the blocking means is reproduced at a distance from the lock housing,

(4) FIG. 3 a blocking means,

(5) FIG. 4 a three-dimensional view of a blocking means in a closing device with a spring element detached from the blocking means, and

(6) FIG. 5 a view of a closing device with a blocking means and a mounted spring element for positioning the blocking means.

(7) A three-dimensional view of a motor vehicle lock or a closing device 1 is reproduced in FIG. 1. The closing device 1 has a lock plate 2, a lock housing 3, a lock lid 4, and a blocking means 5. The closing device 1 is reproduced by the side of the lock plate 2, so that the infeed section 6 is recognizable with the rotary latch arranged in the infeed section 6. The lock plate 2 still supports the bearing axes 8, 9 for the locking mechanism 7. The lock plate 2 is still used as the accommodation for the blocking means 5.

(8) The lock plate 2 also has thread 10, by means of which the closing device 1 can be mounted on, for example, a motor vehicle door. In this embodiment, the lock plate 2 partially encloses the lock housing 3, whereby the lock plate 2 is simultaneously enclosed by the lock housing 3. In the area of the blocking means 5, the lock housing 3 has a recess 11, so that the blocking means 5 can be guided directly through the lock plate 2. A seal ring 12 encloses a cylindrical area of the blocking means 5 and seals the blocking means 5 against the closing device 1.

(9) The blocking means 5 also has an adapter 13, with which the blocking means 5 can interact with, for example, a door skin of a motor vehicle.

(10) FIG. 1 also shows an additional guide means 14, with which the lock 1 can be mounted or other components can be adapted to the lock 1.

(11) In FIG. 2, the closing device 1 is reproduced in a three-dimensional view, whereby the lock lid 4 is reproduced as detached from the closing device 1. It is evident that the lock lid 4 has an opening 15 through which the blocking means 5 can be at least partially guided. It is evident that the area of the opening 15 has a contact surface 16, which is formed as part of the lock lid 4. The contact surface 16 can be provided with a predetermined breaking point, which can be formed in one piece with the contact surface 16 and the lock lid 4. The blocking means 5 is alternatively reproduced without an adapter 13, whereby the blocking means 5 can be positioned, for example, by a compression spring arranged inside the closing device 1.

(12) If an external load F is applied to the closing device 1, the blocking means 5 is moved into the closing device 1 and engages with a trigger lever. In this case, the blocking means 5 is guided in a longitudinally movable manner by means of the lock plate 2 and the lock housing 3, as well as guided at least partially by the lock lid 4. The movement of the blocking means 5 also requires the contact surface 16 to be moved or detached from the lock lid 4.

(13) In FIG. 3, a blocking means 5 is reproduced in the form of a cylindrical pin 17. The blocking means 5 has a ring nut 18, as well as a cylindrical bulge 19, whereby the cylindrical bulge 19

(14) can be used, for example, as a contact surface for a leaf spring. The ring nut 18 in turn can be introduced into the contact surface, for example, so that a form fit can be produced between the blocking means 5 and the contact surface 16.

(15) It is evident at the same time that the blocking means 5 has a pointed contour 20, so that a corresponding contour 20 can be produced between the blocking means 5 and the trigger lever.

(16) In FIG. 4, a three-dimensional view of a closing device 1 is reproduced, whereby a seal ring 21 is square-shaped in this embodiment. The cylindrical bulge 22 has a ring nut 23 into which a spring element 24 can be inserted.

(17) In FIG. 5, an enlarged illustration of the V area from FIG. 4 is reproduced, whereby the spring element 24 is reproduced in a mounted position and engaged with the blocking means 5. The spring element 24 is designed as a leaf spring and engages in the ring nut 23 of the cylindrical bulge 22. Another spring leg 25 encloses the blocking means on the one hand and is fixed between the lock housing 3 and the lock plate 2. The spring element 24 can be used to position the blocking means. Furthermore, a combination of a spring element 24 and a contact surface 16 can be advantageous in preventing an unintentional actuation of the blocking means 5. Due to the inventive formation of the blocking means 5, it is now possible to ensure the safe blocking of a trigger lever in a closing device and to create a constructively favorable and cost-effective way of ensuring the safety of the occupants of a motor vehicle.
