Embodiment Construction

[0067] Figure 1a A safety device 1 for a motor vehicle is shown with a latch 2 , a pawl 3 and a rotary fork 4 . The rotary latch 4 has a load arm 5 , a catch arm 6 , an opening rotational direction 7 , a closing rotational direction 8 , a pre-locking position and a main locking position. The safety device 1 also has an ejection spring 9 for ejecting the latch 2 , which acts on the rotary latch 4 in the opening rotational direction 7 . The catch arm 6 and the load arm 5 form a fork-shaped access opening 13 of the rotary locking fork 4 which receives the latch 2 . The loading arm 5 and the catch arm 6 are at least partially arcuate in design so that the latch 2 can be guided in the access opening 13 during the closing and opening movements of the rotary catch 4 .

[0068] In the opening rotational direction 7 of the rotary catch 4 , the catch arm 6 has a head region 14 with a bend 15 , wherein the bend 15 forms a pre-locking portion 16 . The load arm 5 likewise has a head re...

Abstract

The invention relates to a safety device (1; 101; 201) for a motor vehicle, which has a striker (2; 102; 202), a pawl (3; 103; 203), a rotary latch (4; 104; 204) having an opening direction of rotation (7; 107; 207), a closing direction of rotation (8; 108; 208), and a main locking position, and preferably a front hood (66), wherein the safety device (1; 101; 201) has a blocking element (61; 161;261), which has a blockage position and a release position, and the rotary latch (4; 104; 204) is blocked in the closing direction of rotation (8; 108; 208) in the blockage position of the blocking element (61; 161; 261), wherein the rotary latch (4; 104; 204) is released in the closing direction of rotation (8; 108; 208) by the blocking element (61; 161; 261) in the release position of the blocking element (61; 161; 261) and lowering of the striker (2; 102; 202) is enabled in the main locking position of the rotary latch (4; 104; 204) and movement of the blocking element (61; 161; 261) from the release position to the blockage position is controlled by means of the pawl (3; 103; 203).

Description

technical field [0001] The invention relates to a safety device for a motor vehicle having a latch / block, a pawl and a swivel fork with an opening direction of rotation, a closing direction of rotation and a main locking position. Background technique [0002] A safety device of this type is known from EP 2 096 007 B1 in the form of a pedestrian protection device. Pedestrian protection devices have sensors that detect an object colliding with a motor vehicle and then transmit a signal to a device that projects the rear or front area of ​​the front hatch upwards into the protection area in which the front The hatch is elastically or vibration-dampingly protected downwards in the vertical direction. DE 10 2005 035 006 A1 also discloses a pedestrian protection device in which the front hatch protrudes upwards into the protection point. The pedestrian protection device described therein has locking elements which, when the front hatch is lifted into the protection point, secur...
