But everything but your hands and forearms moves back at least slightly. Here is a super technical sciency drawing illustrating the action:

Nice illustration! Your head does move back relative to its previous position, but the important feature with regards to weight is relative to the points which bear weight. Hands and seat. His head has moved way forward relative to the seat and the red figure has much less weight on his hands than the brown figure.
