Securing device for front hoods, comprising electric drive

Abstract

The invention relates to a securing device (1; 101) for a motor vehicle, having a front hood (2, 102) and a hood lock (3, 103) with a lock holder (10, 110). The hood lock (3, 103) has a rotary latch (4, 104) with a pre-locking position and a main locking position and an electric drive (5, 105) which causes a switchover of the rotary latch (4, 104) from the main locking position into the pre-locking position. In the main locking position, a release of the lock holder (10, 110) is blocked, and the front hood (2, 102) is closed. In the pre-locking position, the lock holder (10, 110) can be manually moved between a closed position, in which the lock holder (10, 110) is engaged with the rotary latch (4, 104) and the front hood (2, 102) is locked, and an open position, in which the lock holder (10, 110) is released from the rotary latch (4, 104) and the front hood (2, 102) is unlocked.

Description

technical field [0001] The invention relates to a safety device for a motor vehicle having a front hood and a hood lock with a lock holder. Background technique [0002] Such a safety device is known from document DE 198 12 835 A1. The safety device described here has a catch hook actuation arrangement which is realized by means of a rod structure and in which no rotating structural elements occur. The safety device is thus characterized by a very simple construction. Opening of the hood takes place from inside the vehicle. Usually, for opening from the inside of the vehicle, the opening mechanism is realized by means of Bowden cables. For example, DE 10 2007 061544 A1 describes an actuating lever for unlocking the engine hood, which is arranged in the passenger compartment and is mechanically connected to the hood lock via a Bowden cable. Furthermore, document DE 10 2005 044 079 A1 discloses unlocking the hood lock by means of a Bowden cable. [0003] The use of Bowden...

AI Technical Summary

Problems solved by technology

[0003] The use of Bowden cables has the disadvantage that the Bowden cables have to be guided from the inside of the vehicle around the components in the engine compartment in the front region of the front hood, requiring space in the engine compartment for this and thus requiring The arrangement of these components in the engine compartment provides less space

Therefore, safety devices according to the prior art limit the possibility of arranging other components in the engine compartment and are therefore impractical in terms of manufacture and construction

Furthermore, the application of a Bowden cable for opening the front hood is not practical for the operator, since the operator has to search for the end of the Bowden cable which is mostly located under the dashboard and has to use a large The force expended to make the Bowden cable move
