The component of claim 1 wherein the web engaging device is adapted to be at least one of: a) lockable in the open condition until manually or automatically toggled into the engaged condition;b) lockable in the engaged position until manually or automatically toggled into the open condition;c) momentarily toggled into the engaged condition; andd) momentarily toggled into the open condition. 3. The component of claim 1, wherein the web engaging device comprises: a web engaging surface configured to engage the webbing in the engaged condition,and a switch that is positionable to cause the web engaging surface to disengage from the webbing and into the open condition. 4. The component of claim 3, wherein the web engaging surface is positioned on a cam. 5. The component of claim 4, wherein the switch includes a lever arm attached to the cam, the lever arm being selectively engageable with a feature of the component to lock the component in the open condition. 6. The component of claim 5, wherein a biasing device is configured to impact the switch to bias the belt engaging surface against the webbing in the engaged condition. 7. The component of claim 1 further comprising, a biasing device configured to bias the web engaging device toward at least one of the open condition and the engaged condition. 8. The component of claim 1, wherein the portion of the buckle assembly includes a slip tongue attached to the webbing, the component further comprising: a yoke for engaging the slip tongue; anda housing for carrying the web engaging device, the housing configured to cooperate with the yoke to secure the component to the vehicle occupant restraint system. 9. The component of claim 8, wherein the housing further comprises an engagement for accepting a portion of the web engaging device when the component is in the open condition such that the web engaging device is lockable and unlockable with the engagement. 10. The component of claim 9, wherein the web engaging device further comprises a resilient retainer element that cooperates with the engagement to toggle the component between the open condition and the engaged condition. 11. The component of claim 1 further comprising, a housing, wherein a portion of the web engaging device is configured to engage with the housing to lock the web engaging device in the open condition. 12. The component of claim 11, wherein the housing engaging portion includes at least one of a spring clip, a sliding retainer, a detent, a servo-relay, an electrical magnet, a permanent magnet, or a pin. 13. The component of claim 1, wherein the component is adapted to permit a tension to be maintained in the lap belt portion that is greater than a tension in the shoulder belt portion when the component is in the engaged condition. 14. The component of claim 1 further comprising, a slip tongue engageable with a buckle. 15. The component of claim 14, wherein the web engaging device is adapted to automatically toggle from the open condition to the engaged condition when the slip tongue is engaged with the buckle. 16. The component of claim 14, wherein the web engaging device is adapted to automatically toggle from the engaged condition to the open condition when the slip tongue is disengaged from the buckle. 17. The component of claim 1, wherein slack developed in the shoulder belt portion is not translatable to the lap belt portion when the component is in the engaged condition. 18. A system including the component of claim 1 and comprising: a tension detector operably engaged with the vehicle occupant restraint system to detect an indicia of tension in the webbing. 19. The system of claim 18, wherein the tension detector includes at least one of a tensiometer, a strain gauge, a resistor wire embedded in the webbing, a webbing deflection detector, a spring-loaded mechanical switch, a pressure applicator applied to the webbing, a sonic detector, an ultra sonic detector, an optical detector, a strain gauge, or an ammeter. 20. The system of claim 18 further comprising: a tensioner configured to tension the webbing to a predetermined tension when a slip tongue of the vehicle occupant restraint system is first engaged with a buckle. 21. The system of claim 18 further comprising: a tensioner configured to tension the webbing after a predetermined time measured from when the web engaging device is toggled from the engaged condition to the open condition. 22. The system of claim 18 further comprising: a tensioner coupled to the tension detector and configured to de-activate upon the detection by the tension detector of a predetermined indicia of tension in the webbing. 23. The system of claim 22, wherein the tension detector is configured to de-activate the tensioner after a predetermined indicia of tension is reached in the lap belt portion. 24. The system of claim 18 further comprising: a tensioner configured to tension the webbing to a tension taken from at least one of a preset tension and a user specified tension. 25. The component of claim 1 further comprising: a housing having two opposing side portions, the web engaging device secured to both side portions such that the web engaging device is pivotable between the opposing side portions to toggle the component between the open condition and the engaged condition; anda switch associated with the web engaging device, positioned within an opening of the housing and configured and dimensioned to toggle the web engaging device between the open condition and the engaged condition. 26. The component of claim 25, wherein a portion of the switch positioned within the housing is accessible to a user when the component is under load. 27. The component of claim 25, wherein the housing further comprises a plate securable to both side portions such that the webbing is disposed between the web engaging device and the plate, the component being configured and dimensioned such that web engaging device urges the webbing against the plate when the component is the engaged condition. 28.
