The invention relates to a device for locking a part (3; 21; 31) that is to be secured, arranged so that it can move on a motor vehicle, a securing part (11; 26; 36) engaging in a slot-shaped cavity (7; 28; 38) of the part (3; 21; 31) that is to be secured under the effect of the acceleration forces

The invention relates to a device for locking a part (3; 21; 31) that is to be secured, arranged so that it can move on a motor vehicle, a securing part (11; 26; 36) engaging in a slot-shaped cavity (7; 28; 38) of the part (3; 21; 31) that is to be secured under the effect of the acceleration forces that occur when the corresponding vehicle coincides with an obstacle. To allow the device to be fitted simply and in a non-bulky way and to reliably prevent unintentional opening of the door of the vehicle when acceleration forces from different directions are applied on the part that is to be secured, the invention proposes that the securing part (11; 26; 36) be controlled by a control element (10; 22; 32) of spherical shape, the control element (10; 22; 32) resting on a guide (8; 23; 33) via domed or conical control surfaces (9).

1. A device for locking a part (3; 21; 31) that is to be secured in a stationary part (2;20; 30), said part being arranged on a motor vehicle so that it can move, said device comprising:a) a spherically-shaped control element (10; 22; 32), a cavity (8; 23; 33) shaped as a guide for the control element (10; 22; 32) which is arranged with respect to the part (3; 21; 31) that is to be secured in said stationary part (2; 20; 30) of the motor vehicle, and a spring (14; 25; 35) which pushes into the guide (8; 23; 33) the control element (10; 22; 32) when the control element (10; 22; 32) is in a normal position; b) the guide (8; 23; 33) for the control element (10; 22; 32) has control surfaces (9) of domed or conical shape which cause a translational movement of the control element (10; 22; 32) toward the part (3; 21; 31) that is to be secured against the action of the pressure of the spring (14; 25; 35) when the vehicle experiences a predetermined variation in motion; c) the part (3; 21; 31) that is to be secured contains, on its side facing the control element (10; 22; 32), a slot-shaped cavity (7; 28; 38), and d) the control element (10; 22; 32) is connected, on a side facing the part (3; 21; 31) that is to be secured, a securing part (11; 26; 36) which acts on an immobilizing pin (13; 27; 37) tailored to the slot-shaped cavity (7; 28; 38) so that the immobilizing pin (13; 27; 37) fits into the slot-shaped cavity (7; 28; 38) when there is a corresponding translational movement of the control element (10; 22; 32).
