A vehicle safety apparatus has a 3-point seatbelt, with a buckle head, and a crash sensor. A pretensioner is connected at the buckle head of the seatbelt for pulling in a length of seatbelt webbing in response to the crash sensor detecting a crash. The pretensioner has a force reservoir and a piston located within and for movement along a pretensioner cylinder under the force of gas from a gas generator. The piston is connected by a cable to the buckle head of the seatbelt. A cable bracket has an inner and outer guide, and wherein the pretensioner cylinder is attached to the inner guide and the buckle mounting is connected to the outer guide.
