Abstract
A seat belt pretensioner acts upon the sill end of a three point seat belt. A fixed member of the pretensioner is adapted to be fixed to a load bearing part of the vehicle. A movable member is connected to the sill end of the seat belt and is slideable with respect to the fixed member. The movable member is moved in a direction that is longitudinal relative to the fixed member to move the sill end of the seat belt in a pretensioning direction in response to a signal from a crash sensor. In this way the sill end of the seat belt is free to move along a connecting member when the seat belt is not under tension either from use in restraining a seat occupant and/or from a pretensioning operation.
