Problems solved by technology

This leads to the disadvantage that the ejection spring requires additional installation space and that the motor vehicle lock occupies a large installation space in the motor vehicle
In addition, the overall weight of the motor vehicle lock increases due to the additional ejection springs in addition to the turning yoke springs

Embodiment Construction

[0039] Figures 1a to 1f with Figures 2a to 2b The motor vehicle safety device 1 is shown during opening. The safety device 1 has a bolt 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 is tensioned in the closing rotational direction 8 of the rotary catch 4 and acts on the rotary catch 4 in the opening rotational direction 7 . The ejector spring 9 preferably has a fixed end 36 , which is supported on a stationary support 37 of the safety device 1 . The fixed end 36 advantageously extends to the bearing sleeve 25 and surrounds the bearing sleeve 25 in such a way that the fixed end 36 cannot move relative to the rotational axis 34 of the ejector spring 9 . The pawl 3 has a pawl spring 10 which acts on the pawl 3 in the locking rota...

Abstract

The invention relates to a safety device (1) for a motor vehicle, which has a striker (2), a pawl, an ejection spring (9) for ejecting the striker (2), and a rotary latch (4), wherein the rotary latch(4) has an opening direction of rotation (7), a closing direction of rotation (8), an open position, and a main locking position. The ejection spring (9) has a leg (27), the leg (27) lies directly against the striker (2) in the main locking position of the rotary latch (4) and the leg (27) lies directly against the rotary latch (4) in at least one intermediate position of the rotary latch (4), inwhich the rotary latch (4) is between the main locking position and the open position.

Description

technical field [0001] The invention relates to a safety device for a motor vehicle with a latch / block, a pawl, an ejection spring for ejecting the latch, and a rotating catch with an opening rotation direction, a closing rotation direction Orientation, open position and master locked position. Background technique [0002] Such a safety device is described in DE 10 2010 037 937 A1, in which an ejection spring is provided to assist when the safety device is displaced from the closed position into the released position. In addition to the ejector spring, the safety device also has a rotary latch spring for loading the rotary latch, wherein the ejector spring is arranged outside the course of the peripheral movement of the rotary latch. This leads to the disadvantage that the ejector spring requires additional installation space and that the motor vehicle lock occupies a large installation space in the motor vehicle. In addition, the overall weight of the motor vehicle lock ...
