  • Patent number: 11882942
    Abstract: An assembly for a seat includes a pivot hub defining multiple rotation axes, and a displacing module attached to the pivot hub. Extendable legs are rotatably coupled to the pivot hub and comprise locking devices movable between an unlocked position, in which the legs, when extended, are enabled to retract, and a locked position, in which the legs, when extended, are prevented from retracting. The legs are rotatable between an intermediate position and a deployed position. When the legs are extended, and when in the intermediate position, the displacing module engages the locking devices to move the locking devices from the locked position to the unlocked position. When the legs are extended, rotating the legs from the intermediate position to the deployed position brings the displacing module out of contact with the locking devices.
