US Patent 11565610 Child safety seat with belt tensioner

A seat base includes abase, an arm and a release mechanism. The base includes a capture mechanism. The arm is coupled to the base and rotates through release, tension and unloaded positions. The arm frictionally engages a vehicle belt disposed between the arm and the base. The belt is disengaged from the arm when the arm is disposed in the release position. The capture mechanism is movable between an engaged position in which the arm is precluded from moving into the release position, and a disengaged position in which the arm is free to move into the release position. When the arm is disposed in the tension position and the capture mechanism is disposed in the engaged position, the capture mechanism is precluded from moving into the disengaged position. The release mechanism releases the arm from the capture mechanism when the arm is disposed in the unloaded position
