Abstract
A pretensioning apparatus for seat belt webbing is located in the vicinity of a belt anchor end of a three-point vehicle safety restraint seat belt. The pretensioning apparatus has a fixed member in the form of a tubular member that may be anchored to a vehicle seat at the belt anchor side of the vehicle. A movable member in the form of a piston is connected to the webbing in the region of the belt anchor end. A means is provided for moving the movable member relative to the fixed member in a generally horizontal direction, to move the seat belt webbing in a pretensioning direction in response to a signal from a crash sensor. A webbing guide is fixed to the seat to provide an effective anchorage point spaced from the belt anchor end of the webbing under pretensioning conditions.
