Abstract

The present invention relates to a safety system (1) of a vehicle bonnet lock control lever (2) consisting of a mounting base (3) with a supporting plate (5) being attached thereto at a certain distance therefrom by means of screws (4). A rotary shaft (6) with a control lever (2), a torsion spring (18) and an arm (7) attached to its one end passes through the mounting base (2) and the supporting plate (5). A control cable (8) passing through a Bowden (9) attached to the mounting base (3) is fastened at the end of the arm (7). A lock barrel (10) with an adapter (11) being provided on its front wall (12) with a pin (13) passes through both said mounting base (2) and said supporting plate (5) whereby the pin (13) is slidably mounted in an elongate hole (14) performed in a catch (15). The catch (15) is provided on its side with a safety surface (16) for supporting a ratchet (17) attached to the other end of the rotary shaft (6).

Description

Bonnet Lock Control Latch System

Technical field

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a locking system for a vehicle bonnet lock lever by means of a locking mechanism securing the lever in a non-operative position by a lock cylinder.

and

BACKGROUND OF THE INVENTION

Until now, a simple system has been used to unlock the bonnet lock, in which the lock control lever is located in the interior of the vehicle on the inner Asloup or under the steering wheel on the dashboard and is easily accessible and in no way secured. Bowden transmits the pivoting movement of the lever to the lock where it unlocks its latch. The disadvantage of this simple system is the absolute resistance to intrusion into the engine compartment, where the control unit is located, when the car immobilizer is deactivated and stolen.

Another known device for securing the hood of a vehicle, which is opened by means of a cable from the interior, is the use of a second securing cable guided from the interior of the vehicle. The latter comprises a pair of sliders mounted slidably in the console, one of which is coupled to the car bonnet lock latch and the other slider coupled to the additional lock mechanism, the other slider being slidably mounted in the path of the first slider. The first slider is spring-loaded and is connected by a cable to the latch to which the bonnet lock cable operated from the interior by a control lever is fastened from the other side. The first rider is provided with a groove into which the front of the second rider engages in a locked state. The disadvantage of this solution is that the lock can be opened by a lever from the interior in case of a forced break of the belay cable.

This disadvantage is overcome by a solution having a notch on each of the sliders for the arresting member and both sliders being sprung by a separate spring. The disadvantage of this solution is that even if the safety wire is forcibly interrupted, even the owner of the key from the additional lock device will not enter the engine compartment.

2. Summary of the Invention

These drawbacks are largely overcome by the vehicle bonnet lock control lever locking system consisting of a base plate to which a support plate is rotatably mounted by means of a screw. A swivel shaft extends through the base plate, at the end of which a control cable is fastened through a bowden cable fixed to the base plate, in which the lock insert is secured by the carrier plate in a certain position. The lock insert is provided with an extension having an eccentrically located pin on its front wall, which moves in an elongated hole formed in a pawl rotatably mounted on a support plate. The latch is provided on the side with a locking surface for supporting the ratchet mounted at the other end of the rotary shaft.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. Fig. 2 is an axonometric view of the actuating lever from the rear in the locked position; Fig. 2 is an axonometric view of the locked position; and Fig. 3 is an axonometric view of the front, ie from the interior of the vehicle.

DETAILED DESCRIPTION OF THE INVENTION

The locking mechanism I of the control lever 2 consists of a base plate 3, to which a support plate 5 is fastened by means of screws 4. A rotatable shaft 6 extends through these plates 3.5. On one end of the shaft 6, on the outside of the base plate 3, the control lever 2 is fixed, on the inner side of the base plate 3 is a torsion spring 18 returning the lever 2 to the rest position and in the middle part of the shaft 6 is fixed arm 7, at the end of which the control cable 8 is fastened. The lock plate 10 provided with an extension 11 having an eccentrically formed pin 13 on the side of the end wall 12, which is slidably inserted in the elongated hole 14. The elongated hole 14 is formed in the latch 15, which is rotatably mounted on the support plate 5 and has a locking surface 16 on the side. The locking surface 16 is intended to support the ratchet 17 mounted at the other end of the rotary shaft 6. When the lever 2 is locked, the ratchet 17 is supported on the locking surface 16 of the latch 15 and the bonnet lock cannot be opened. When the lock cylinder 10 is rotated to the unlocked position, the lock cylinder 10 is in the unlocked position. When the pin 13 moves the latch 15 to the side away from the shaft 6, it is possible to retract it by means of the control lever. 2 over the arm 7 by the cable 8 to open the bonnet lock.
