ABSTRACT:
A safety device for a vehicle sliding door which detects any obstacle hindering the door closing movement and which cannot injure a passenger struck by the door. The door closing force is limited to a non dangerous value and the door comprises a tongue groove joint surrounded by a flexible lip joint. An obstacle is first struck by the flexible lips and only after retraction of these lips by the tongue. The presence of this obstacle hinders the penetration of the tongue into the groove and the closing of the door.
