Abstract

A blocking device that includes a blocking pin movable on the first element between an unblocked position and a blocked position, and an actuating element secured to the second element and arranged to move the blocking pin. The blocking pin is fastened to the first element by a stressing element arranged to exert a force stressing the blocking pin toward its unblocked position between the unblocked position and an intermediate position of the blocking pin, and to exert a force stressing the blocking pin toward its blocked position between the intermediate position and the blocked position of the blocking pin.

First claim

The invention claimed is:

1. A blocking device for a vehicle, comprising:
a first element;
a second element, wherein the second element is moveable relative to the first element;
a blocking pin movable between a first end part and a second end part relative to the first element, the blocking pin being movable between an unblocked position and a blocked position, wherein in the blocked position, said blocking pin is located at the second end part;
an actuating element secured to the second element, separate from the blocking pin, and arranged to move into contact with the blocking pin between the unblocked position and the blocked position during at least part of the movement of the second element relative to the first element and the actuating element is configured to be spaced from the blocking pin during at least part of the movement of the second element relative to the first element when the blocking pin is in the unblocked position; and
a stressing element that fastens the blocking pin to the first element, said stressing element being moved with the blocking pin by the actuating element and being arranged to exert a force stressing the blocking pin toward its unblocked position when the blocking pin is between the unblocked position and an intermediate position of the blocking pin and to exert a force stressing the blocking pin toward its blocked position when the blocking pin is between the intermediate position and the blocked position of the blocking pin so that movement of the actuating element is required to move the second element relative to the first element when the blocking pin is in the blocked position.

2. The blocking device according to claim 1 , wherein the stressing element comprises a first branch extending from a spring to a first end rotatably mounted on the first element and a second branch extending from the spring to a second end secured to the blocking pin, wherein the spring is arranged to exert the stressing force on the blocking pin and the first and second branches form a non-zero angle (α) between them.

3. The blocking device according to claim 1 , wherein the blocking pin is movable in a groove provided on the first element, the shape of said groove defining the path of said pin between its unblocked position and its blocked position.

4. The blocking device according to claim 3 , wherein the groove extends substantially rectilinearly between the first and the second end part in a movement direction (F) of the second element relative to the first element, the first and second end parts each forming a non-zero angle with the rectilinear portion of the groove, the blocking pin being found in the first end part in the unblocked position.

5. The blocking device according to claim 3 , wherein the device comprises a stop element, the blocking pin abutting against said stop element when the blocking pin is in the first end part of the groove.

6. The blocking device according to claim 1 , wherein the actuating element comprises a housing with a shape substantially complementary to the shape of part of the blocking pin, said blocking pin engaging in said housing during its movement between its unblocked position and its blocked position and being retained in said housing in the blocked position.

7. The blocking device according to claim 6 , wherein the actuating element comprises an engaging surface emerging on the housing, said engaging surface coming into contact with the blocking pin in the unblocked position and guiding said blocking pin toward the housing during the movement of said blocking pin toward its blocked position.

8. A storage device for a vehicle, comprising a blocking device according to claim 1 , wherein the first element is a support element and the second element is a storage element defining a storage volume, said storage element being translatable relative to the support element between a closed position, in which the support element closes the storage volume, and an open position, in which the storage element is removed from the support element and the storage volume is accessible, wherein the blocking pin of the blocking device is in its blocked position when the storage element is in its open position.

9. The storage device according to claim 8 , wherein the movement between the unblocked position and the blocked position of the blocking pin corresponds to a translation of the storage element at the end of travel in the vicinity of the open position of the storage element.

10. The blocking device according to claim 1 , wherein the first element comprises a support plate.
