## Abstract

The device comprises a main body, a fixing member affording fixing of a door leaf to the main body, a ball socket able to drive the main body under the effect of a motor, a roller able to move between (a) an active locking position in which the roller locks the ball socket with respect to the main body, in a closed position of the door leaf and (b) an inactive unlocking position in which a the roller allows displacement of the ball socket with respect to the main body. The device also includes a sleeve that allows a small movement of the fixing member with respect to the ball socket in a displacement direction from the closed position of the door leaf. The device further comprises a tooth that inhibits sleeve to immobilize the fixing member with respect to the ball socket, at least in translation in the displacement direction, when the roller is in the inactive position.

## Claims

### Claim 1

A displacement device for displacing a door leaf with respect to a vehicle body, the door leaf being movable in a displacement direction between a closed position and an open position with reference to an opening provided in the vehicle body, the displacement device comprising:
a main body;
a fixing member configured to fix the door leaf to the main body;
a ball socket configured to drive the main body under operation of a motor;
a roller configured to move between fa) an active locking position in which the roller locks the ball socket with respect to the main body in a closed position of the door leaf and (b) an inactive release position in which the roller allows displacement of the ball socket with respect to the main body;
a sleeve configured to allow a limited movement of the fixing member with respect to the ball socket in a movement direction from the closed position of the door leaf; and
an inhibition device for inhibiting movement of the sleeve and configured to immobilize the fixing member with respect to the drive means ball socket at least in translation in the displacement direction while the roller is in the inactive release position.

### Claim 2 (depends on 1)

The displacement device according to claim 1, wherein the inhibition device is configured to move between an active inhibition position and an inactive inhibition position, the inhibition device configured to rotate from the active inhibition position to the inactive inhibition position from movement of the roller from the inactive release position to the active locking position.

### Claim 3 (depends on 2)

The displacement device according to claim 2, wherein the inhibition device is configured to rotate from the inactive inhibition position to the active inhibition position from passage of the roller from the active locking position to the inactive release position.

### Claim 4 (depends on 1)

The displacement device according to claim 1, wherein the roller is secured to the inhibition device in rotation about the displacement direction.

### Claim 5 (depends on 1)

The displacement device according to claim 1, wherein the roller is coupled to the main body by a radially extending arm.

### Claim 6 (depends on 1)

The displacement device according to claim 1, wherein the inhibition device includes a ring coaxially mounted with respect to the main body and an inhibition tooth projecting radially from the ring.

### Claim 7 (depends on 6)

The displacement device according to claim 6, wherein the fixing member defines a recess positioned to receive the inhibition tooth.

### Claim 8 (depends on 7)

The displacement device according to claim 7, wherein, in an inhibition position, the inhibition tooth is in abutment against walls of the recess in the displacement direction.

### Claim 9 (depends on 1)

The displacement device according to claim 1, wherein the sleeve is coaxially mounted with respect to the main body the sleeve constrained to move at least in translation with the fixing member in the displacement direction.

### Claim 10 (depends on 9)

The displacement device according to claim 9, wherein the sleeve is configured to move on a principal axis of the main body with respect to the ball socket and counter to a spring having a first end that bears against a stop cover mounted on the main body and a second end that bears against the sleeve.

### Claim 11

A door for a vehicle, the door including a fixed frame secured to a vehicle frame of the vehicle, at least one door leaf, and at least one displacement device configured to move the at least one door leaf in a displacement direction with respect to the fixed frame, the displacement device including:
a main body;
a fixing member configured to fix the at least one door leaf to the main body;
a ball socket configured to drive the main body under operation of a motor;
a roller configured to move between (a) an active locking position in which the roller locks the ball socket with respect to the main body in a closed position of the at least one door leaf and (b) an inactive release position in which the roller allows displacement of the ball socket with respect to the main body;
a sleeve configured to allow a limited movement of the fixing member with respect to the ball socket in a movement direction from the closed position of the at least one door leaf: and
an inhibition device for inhibiting movement of the sleeve and configured to immobilize the fixing member with respect to the ball socket at least in translation in the displacement direction while the roller is in the inactive release position.

### Claim 12

A vehicle comprising at least one door having a fixed frame secured to a vehicle frame of the vehicle, at least one door leaf, and at least one displacement device configured to move the at least one door leaf in a displacement direction with respect to the fixed frame, the displacement device including:
a main body;
a fixing member configured to fix the at least one door leaf to the main body;
a ball socket configured to drive the main body under operation of a motor;
a roller configured to move between (a) an active locking position in which the roller locks the ball socket with respect to the main body in a closed position of the at least one door leaf and (b) an inactive release position in which the roller allows displacement of the ball socket with respect to the main body;
a sleeve configured to allow a limited movement of the fixing member with respect to the ball socket in a movement direction from the closed position of the at least one door leaf: and
an inhibition device for inhibiting movement of the sleeve and configured to immobilize the fixing member with respect to the ball socket at least in translation in the displacement direction while the roller is in the inactive release position.
