NOVELTY - A bolt assembly includes a shank (12) with a screw thread that is adapted to rotatably engage with a complementary screw thread in a nut and a head (14) of larger cross section than that of the shank. It has a disengaging mechanism adapted to disengage the head or nut without rotation of the nut or the shank. The disengaging mechanism includes a material (18) adapted to change form to facilitate disengagement, when activated.    USE - The inventive assembly is used as a seat belt anchor. It can also be used to secure not only seat belts and doors but also spare tires and roof racks.    ADVANTAGE - The inventive assembly provides a bolt that is capable of providing quick release, especially remote quick release. If the inventive bolt assembly is used as a seat belt anchor, individuals in a severe automobile crash can be released from their seat belts where the individuals are disabled or where the seat belt release mechanism has been damaged.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (a) a method of releasing the bolt assembly when engaged with the nut, comprising activating the material to change form to enable disengagement of the head or the nut without rotation of the nut or the shank;    (b) a device for releasing the bolt assembly when engaged with the nut, comprising a conveying mechanism for conveying a wireless command for activating the material to change form to enable disengagement of the head or the nut without rotation of the nut or the shank;    (c) a computer system including a first enquiring mechanism for enquiring as to identification in a target, a first receiving mechanism for receiving identification data from the target, a first database for comparing the identification data with stored data, a second enquiring mechanism for enquiring as to status in the target, a second receiving mechanism for receiving status data from the target, a second database for comparing the status data with stored data and a transmitting mechanism for transmitting a command to the target to change the status; and    (d) a method including the steps of enquiring as to identification in a target, receiving identification data from the target, comparing the identification data with stored data in a database, enquiring as to status in the target, receiving status data from the target, comparing the status data with stored date in a database and authorizing the change in the status.    DESCRIPTION OF DRAWING(S) - The figure is a side elevation, partly in cross section, of a bolt assembly in which a head of a bolt is designed to disengage.
