A re-settable vehicle seat belt pre-tensioner apparatus is disclosed having a first member engagable with a second member that is moveable relative to the first member, and re-settable in response to various sensed driving conditions to pretension the seat belt around the operator and return to a non pre-tensioned status when the driving conditions have passed. The apparatus may be operated by positioning the belt for use; determining whether the seat belt buckle is in use; locking the pre-tensioner and lowering the seat belt buckle below the seat occupation plane; determining whether a threshold vehicle seat belt pre-tension load has been met; raising the belt buckle to a design position, unlocking the retractor; determining whether a threat event is imminent and locking the retractor; lowering the vehicle seat buckle relative to the plane of occupation, determining whether a crash event is occurring, and if yes, deploying a pyrotechnic deployment to secure the occupant in the seat.

What is claimed as new and desired to be protected by Letters Patent of the United States is: 1. A re-settable vehicle seat belt pre-tensioner presenter apparatus, comprising:a first member engaged with a second member moveable relative to said first member; said second member capable of receiving a seat belt tongue insert; said first member driveably connected to a variable reversible drive motor; said apparatus further equipped with a re-settable seat belt buckle and the drive motor also acting as a belt pre-tensioner adjustor; said adjustor adapted to adjust said seat belt buckle to a desired position relative a seat to facilitate easy access by an operator; said seat belt buckle and belt pre-tensioner adjustor further acting as a re-settable seat belt pre-tensioner in response to various sensed driving condition inputs to resettably pre-tension said seat belt around said operator during pre-crash and crash conditions, and return to non pre-tension status when said pre-crash conditions have passed.
