Child safety seat with belt tensioner

A child safety seat comprising:

• a seat base;
• and
• a seat body detachably coupled to the seat base;
• wherein the seat base includes:
• a base portion;
• and
• a belt tensioning system,
• wherein the belt tensioning system includes:
• a tensioning arm pivotably coupled to the base portion and movable through a release position, a tension position and an unloaded position, the tensioning arm being configured to frictionally engage a vehicle belt disposed between the tensioning arm and the base portion when the tensioning arm is disposed in the tension and unloaded positions, the belt being disengaged from the tensioning arm when the tensioning arm is disposed in the release position;
• and
• a release mechanism coupled to the tensioning arm;
• and
• a capture mechanism coupled to the base portion and movable between
• (i) an engaged position in which the tensioning arm is precluded by the capture mechanism from moving into the release position, and (ii) a disengaged position in which the tensioning arm is free to move into the release position,
• wherein, when the tensioning arm is disposed in the tension position and the capture mechanism is disposed in the engaged position, the belt applies a load to the capture mechanism via the tensioning arm and the capture mechanism is precluded from moving into the disengaged position, and
• wherein the release mechanism is configured to release the tensioning arm from the capture mechanism when the tensioning arm is disposed in the unloaded position, the load being removed from the capture mechanism when the tensioning arm is disposed in the unloaded position.
