Abstract

The invention concerns a securing device for swivelling components of vehicles, in particular for engine hoods of motor vehicles. A securing hook which, after the release of the swivelling component, initially maintains a catch connection between this swivelling component and a fixed location mating component until the securing hook is pivoted into a release position by means of a manipulator. The manipulator, which is recessed when the swivelling component is locked, is automatically transferred into an accessible operating position by utilization of a forced advancement of the swivelling component relative to the mating component initiated by the release procedure. A control edge effectively connected to the manipulator and supported on the mating component is moved in the opening direction of the securing hook by sliding along the mating component. In order to permit an increase in the automatic manipulator advancement without doubts about safety and without sacrifices to operational comfort, the control edge is part of a control hook which is supported so that it can move relative to the securing hook and the motion of the control hook is only coupled to that of the securing hook after it is in advance of the latter.

Claims

1. Securing device for securing a vehicle hood at a vehicle fixed part, said securing device comprising:

a securing hook member which is engageable with a vehicle fixed part to secure the hood against excess inadvertent opening movement when the hood is released so as to move from a closed position to a partial opened position,

a manipulator which automatically moves from an inexcessible recessed position to an excessible manually engageable position outside a hood compartment in response to movement of the hood from the closed position to the partial opened position,

and a control member which is pivotable about a vehicle transverse axis, said control member including a control edge which slidably engages the fixed part to be forcibly pivoted thereby, said control member being hingeably connected to the manipulator so as to move the manipulator axially of the vehicle to its accessible position in response to forced pivotal movement of the control member by way of engagement of the control edge and fixed part.

2. Securing device according to claim 1, wherein the motion of the control member is coupled to that of the securing hook in the operating position of the manipulator.

3. Securing device according to claim 1, wherein the securing hook and the control member are hinged on a common axis.

4. Securing device according to claim 1, wherein the control edge is formed integrally on the control member.

5. Securing device according to claim 2, wherein a plate stop which makes contact as an area with a rear edge of the securing hook is provided as the control edge.

6. Securing device according to claim 4, wherein a plate stop which makes contact as an area with a rear edge of the securing hook is provided as the control edge.

7. Securing device according to claim 5, wherein the plate stop is extended by a guide strap angled approximately parallel to the plane of oscillation of the securing hook.

8. Securing device according to claim 6, wherein the plate stop is extended by a guide strap angled approximately parallel to the plane of oscillation of the securing hook.

9. Securing device according to claim 1, wherein the securing hook and the control member are spring-loaded independently of one another in the direction of their securing advancement.

10. Securing device according to claim 2, wherein the securing hook and the control member each have a return lug which, in the course of the closing procedure of the hood and in the case of a failure of the associated spring, carries out the securing advancement of the securing hook, and control member by making contact with a surface of the mating component.

11. Securing device according to claim 1, wherein the control member consists of plastic.
