US Patent 7249784 Safety arrangement

The safety arrangement for a motor vehicle incorporates primary restraint arrangement having a three-point seat-belt (3) and optionally one or more air-bags (19,22). A secondary restraint system is provided in the form of a two-point seat-belt (13). A sensor senses when the two-point seat-belt (13) is in use and provides a signal to a control unit (17) which adjusts the restraining effect provided by the primary restraint arrangement so that the overall restraining effect is the same regardless of whether the two-point seat-belt is, or is not, used. The use of the two-point seat-belt (13) provides enhanced occupant protection especially in a side-impact or rollover situation.
