Vehicle warning devices
First Claim
1. In a device for detecting and recording the occurrence of excessive inertial forces acting on a vehicle, said device having force detecting means actuated when excessive forces are acting on said vehicle, indicator means responsive to said force detecting means for indicating "faults" when said detecting means is actuated, said indicator means including timing means for preventing said indicator means from indicating additional "faults" during a predetermined time interval following the indication of a "fault," the improvement comprising counting means responsive to said indicator means and said detecting means for counting "faults" and for disabling said indicator means from indicating "faults" when the number of "faults" counted during a single actuation of said detector means exceeds a predetermined number.

Abstract
A safety device for use particularly with vehicles embodies a switching arrangement which is closed when excessive accelerative forces are applied thereto. Recording means are included to record "faults" sensed by the device and means are also provided for limiting the number of "faults" recorded by the device during a single prolonged closure of the switching arrangement.

11. A device for detecting and recording occurrences of excessive inertial forces acting on a vehicle comprising:
-
detecting means actuated when excessive inertial forces are acting on a vehicle, indicator means responsive to said detecting means for indicating "faults" when said detecting means is actuated, and counting means responsive to said detecting means and said indicator means for counting "faults" and preventing said indicating means from indicating "faults" when the number of "faults" counted during a single actuation of said detecting means exceeds a predetermined number. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A device for detecting and recording occurrences of excessive inertial forces acting on a vehicle comprising:
-
detecting means actuated when excessive inertial forces are acting on a vehicle, indicator mean responsive to said detecting means for indicating "faults" when said detecting means is actuated, said indicator means including first timing means for preventing said indicating means from indicating additional "faults" during a first predetermined time interval following the indication of a "fault", second timing means for preventing said indicator means from indicating a "fault" until said detecting means remains actuated for a second predetermined time interval, first counter responsive to said indicator means to count the total number of "faults" indicated, second counter responsive to said indicator means and said detecting means for counting "faults" and for disabling said indicator means from indicating "faults" when the number of "faults" counted during a single actuation of said detector means exceeds a predetermined number, means for resetting said second counter in response to termination of said actuation of said detecting means, and means for controlling said reset means to prevent reset of said second counting means until the termination of actuation of said detecting means persists continuously for a third predetermined time interval. - View Dependent Claims (30)
