1. A seat belt arrangement comprising: a buckle configured to secure a latch when said latch is engaged with said buckle;release means associated with said buckle and being configured to allow release of said latch from engagement with said buckle upon action of said release means;a lock operatively associated with said buckle and said release means, said lock being configured to prevent activation of said release means in a first position of said lock, and to allow activation of said release means in a second position of said lock; anda switch configured in said buckle to be activated to dispose said lock in said first position, and be deactivated to dispose said lock in the second position;wherein said switch is activated by said latch when said latch is engaged with said buckle to dispose said lock in said first position, and is selectively deactivated upon activation of a remote activation means to dispose said lock in said second position. 2. The seat belt arrangement according to claim 1, further comprising; a chassis to accommodate the release means for action to allow the release of said latch from engagement with said buckle, said chassis normally biasing said release means to an inactive position from where said release means can be actioned to allow said release;wherein the lock comprises a solenoid, a locking plate operatively associated with the solenoid, and a biasing means configured to bias said locking plate to dispose said lock in said second position; andwherein said solenoid is able to be energised to move said locking plate to dispose said lock in said first position. 3. The seat belt arrangement according to claim 2, wherein an initial voltage is delivered to said solenoid to energise said solenoid and move said locking plate to dispose said lock in said first position, and then said initial voltage being reduced to hold said solenoid in said energised state and maintain said locking plate to dispose said lock in said first position with very low heat dissipation and low current for an indefinite period. 4. The seat belt arrangement according to claim 2, wherein said chassis includes a stop and said release means includes a stop confronting portion, whereby said release means is actioned to allow said release when said stop confronting portion proximately confronts said stop; said lock is disposed in said first position when said locking plate is moved to a position interposed between said stop confronting portion and said stop to prevent said stop confronting portion from proximately confronting said stop. 5. The seat belt arrangement according to claim 1, wherein said remote activation means is a remote switch configured within a vehicle comprising the seat belt arrangement. 6. The seat belt arrangement according to claim 1, further comprising an indicator to indicate whether said lock is in said first position or said second position. 7. The seat belt arrangement according to claim 1, wherein said lock moves to said second position upon opening an ignition switch of a vehicle comprising the seat belt arrangement. 8. The seat belt arrangement according to claim 1, wherein said switch is a micro-switch. 9. The seat belt arrangement according to claim 1, wherein said switch is a reed switch. 10. The seat belt arrangement according to claim 9, further comprising a magnet, said magnet being moved by said latch when said latch is inserted in said buckle to activate said reed switch. 11. A seat belt arrangement comprising: a buckle configured to secure a latch when said latch is engaged with said buckle; a locking plate operatively associated with said buckle, said locking plate being configured to prevent release of said latch from engagement with said buckle in a first position and to allow release of said latch from engagement with said buckle in a second position; anda switch configured in said buckle;wherein said first position is determined through activation of said switch, and said switch being activated by said latch when said latch is engaged with said buckle. 12. The seat belt arrangement according to claim 11, further comprising a solenoid operatively associated with said locking plate, said solenoid being energised to move said locking plate to said first position. 13. The seat belt arrangement according to claim 12, wherein an initial voltage is delivered to said solenoid to energise said solenoid and move said locking plate to said first position, and then said initial voltage being reduced to hold said solenoid in said energised state and maintain said locking plate in said first position with very low heat dissipation and low current for an indefinite period. 14. The seat belt arrangement according to claim 11, wherein said switch is a micro-switch. 15. The seat belt arrangement according to claim 11, wherein said switch is a reed switch. 16. The seat belt arrangement according to claim 15, further comprising a magnet, said magnet being moved by said latch when said latch is engaged with said buckle to activate said reed switch. 17. The seat belt arrangement according to claim 11, further comprising: a release means associated with said buckle and being configured to allow release of said latch from engagement with said buckle upon action of said release means; anda chassis to accommodate the release means for action to allow the release of said latch from engagement with said buckle, said chassis normally biasing said release means to an inactive position from where said release means can be actioned to allow said release. 18. The seat belt arrangement according to claim 17, wherein said chassis comprises: a stop and said release means includes a stop confronting portion, whereby said release means is actioned to allow said release when said stop confronting portion proximately confronts said stop;wherein said lock is disposed in said first position when said locking plate is moved to a position interposed between said stop confronting portion and said stop to prevent said stop confronting portion from proximately confronting said stop.
