Abstract
Abstract A thermally actuated seat belt fastener includes a conventional latching mechanism having an automotive thermostat type of actuator within a release button that is pressed by a user to release the fastener. If the thermostat is subjected to a predetermined high temperature, an internal plunger extends from the interior of the button to automatically release the fastener, without depressing of the release button.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
149 words
A seat belt fastener comprising in combination: (a) a tongue member including a transverse retaining edge; (b) a latch mechanism including a movable retaining member for engaging the transverse retaining edge to prevent removal of the tongue member from the latch mechanism; (c) release button means in the latch mechanism for moving the movable retaining member away from the transverse retaining edge as the release button means is depressed by a user to release the seat belt fastener; and (d) temperature-sensitive means within the release button means for forcing a thrust member from the release button means against the movable retaining member to move it away from the transverse retaining edge if the temperature of the release button means exceeds a predetermined level, thereby automatically releasing the seat belt fastener without depressing of the release button means if the temperature of the release button means exceeds the predetermined level.
Claim 2
Dependent Claim
149 words
A seat belt fastener comprising in combination: (a) a tongue member including a transverse retaining edge; (b) a latch mechanism including a movable retaining member for engaging the transverse retaining edge to prevent removal of the tongue member from the latch mechanism; (c) release button means in the latch mechanism for moving the movable retaining member away from the transverse retaining edge as the release button means is depressed by a user to release the seat belt fastener; and (d) temperature-sensitive means within the release button means for forcing a thrust member from the release button means against the movable retaining member to move it away from the transverse retaining edge if the temperature of the release button means exceeds a predetermined level, thereby automatically releasing the seat belt fastener without depressing of the release button means if the temperature of the release button means exceeds the predetermined level.
Claim 3
Dependent Claim
46 words
The seat belt fastener of claim 1 wherein the temperature-sensitive means includes a rubbery blended wax material engaging the thrust member and forcing the thrust member to move out of the release button means when the temperature of the release button means exceeds the predetermined temperature.
Claim 4
Dependent Claim
21 words
The seat belt fastener of claim 2 wherein the release button means includes an automotive engine coolant thermostat type of element.
Claim 5
Dependent Claim
61 words
The seat belt fastener of claim 3 including a housing having an opening through which a portion of the release button means extends a predetermined distance to improve transfer of heat in a passenger compartment to the temperature-sensitive means in order to rapidly automatically release the seat belt fastener upon the occurrence of a high temperature condition in the passenger compartment.
Claim 6
Dependent Claim
144 words
A seat belt fastener comprising in combination: (a) a tongue member including a transverse retaining edge; (b) a latch mechanism including a movable retaining member for engaging the transverse retaining edge to prevent removal of the tongue member from the latch mechanism; (c) release button means in the latch mechanism for moving the movable retaining member away from the transverse retaining edge as the release button means is depressed by a user to release the seat belt fastener; and (d) temperature-sensitive means for forcing a thrust member from the release button means against the movable retaining member to move it away from the transverse retaining edge if the temperature of the release button means exceeds a predetermined level, thereby automatically releasing the seat belt fastener without depressing of the release button means if the temperature of the release button means exceeds the predetermined level.
Claim 7
Dependent Claim
144 words
A seat belt fastener comprising in combination: (a) a tongue member including a transverse retaining edge; (b) a latch mechanism including a movable retaining member for engaging the transverse retaining edge to prevent removal of the tongue member from the latch mechanism; (c) release button means in the latch mechanism for moving the movable retaining member away from the transverse retaining edge as the release button means is depressed by a user to release the seat belt fastener; and (d) temperature-sensitive means for forcing a thrust member from the release button means against the movable retaining member to move it away from the transverse retaining edge if the temperature of the release button means exceeds a predetermined level, thereby automatically releasing the seat belt fastener without depressing of the release button means if the temperature of the release button means exceeds the predetermined level.
