Securing device with a front hood and a bayonet-type closure system

Abstract

The invention relates to a securing device (1), which has a front hood (2) and a hood lock (3) with a lock holder (10), for a motor vehicle. The hood lock (3) has a rotary latch (4) with a pre-latching position and a main latching position in which the front hood (2) is closed and locked, an electric drive (5) which switches the rotary latch (4) from the main latching position into the pre-latching position, and a bayonet-type closure system (13) with a closed position, a release position, and an intermediate position. In the closed position, the rotary latch (4) is located in the main latching position; in the intermediate position, the rotary latch (4) is located in the pre-latching position and the lock holder (10) is engaged with the rotary latch (4); and in the release position, the lock holder (10) is released by the rotary latch (4) and the front hood (2) is unlocked.

Description

technical field [0001] The invention relates to a security device for a motor vehicle comprising a front hatch and a hatch lock with a catch. Background technique [0002] DE 19812835 A1 discloses a safety device as described above. The safety device disclosed therein has a rotary yoke actuating device which is realized by means of a lever mechanism and in which no rotating parts are present. This safety device is therefore characterized by a very simple construction. The first step for unlocking the front hatch is usually carried out from the inside of the vehicle by operating a Bowden cable. Thus, for example, DE 10 2007 061 544 A1 discloses an operating lever for unlocking the bonnet, which is arranged in the passenger compartment and is mechanically connected to the hood lock via a Bowden cable. Furthermore, DE 10 2005 044 079 A1 discloses an unlocking mechanism of a hatch lock by means of a Bowden cable. [0003] The use of Bowden cables has the disadvantage that th...

AI Technical Summary

Problems solved by technology

[0003] The use of Bowden cables has the disadvantage that the Bowden cables have to be guided around several components in the engine compartment from the vehicle interior up to the front region of the front hatch in which the hatch lock is arranged, for which an engine compartment is required. space, thereby using a small amount of space in the engine compartment for these components

Therefore, the safety device according to the prior art limits the possibility of arranging other components in the nacelle and is thus impractical in terms of manufacturing and design technology

Furthermore, using the Bowden cable for unlocking the front hatch is not practical for the operator, who must fumble in search of one end of the Bowden cable, which is usually located under the dashboard and can only be accessed with a considerable force required to move the Bowden cable
