Vehicle restraint device

A restraint device for restraining a vehicle to a fixed structure, the device comprising:

• a frame securable to the fixed structure;
• a pivot member having a first end pivotally secured to the frame and a second end with a hooking member opposite the first end, the pivot member being pivotable on said first end between an upwards operative position and a downwards inoperative position;
• biasing means for biasing the pivot member in the upwards operative position;
• means for bringing back the pivot member from the upwards operative position to the downwards inoperative position;
• the means for bringing back the pivot member from the upwards operative position to the downwards inoperative position comprising:
• an actuator member mounted in the vicinity of the pivot member for vertical sliding movement with respect to the frame, the actuator member having a top end portion opposite a bottom end portion respectively located above and below the first end of the pivot member, and
• a linking member having a first end pivotally connected to the bottom end portion of the actuator member and a second end opposite the first end pivotally connected to the pivot member at a location between the first and second end thereof;
• the actuator member being movable along a vertical line between an upwards position obtained when the pivot member is biased in the upwards operative position and a downwards position which causes the pivot member to move in the downwards inoperative position.
