1. An impact sensor assembly for an automotive vehicle, the sensor assembly comprising:
- (a) a sensor for sensing an impact and providing a signal in response to the impact; and
(b) a bracket for mounting the sensor to the automotive vehicle, the bracket including;
i) a first panel attached to an inner portion of the automotive vehicle and attached to the sensor; and
ii) a second panel extending away from the first panel toward an outer body panel of the automotive vehicle, the second panel of the bracket extending beyond the sensor toward the outer body panel of the vehicle thereby extending the sensing area of the sensor;
wherein the impact deforms the outer body panel to initiate contact between the second panel of the bracket and the outer body panel such that the second panel transmits an acceleration or deceleration caused by the contact to the sensor.

8. An impact sensor assembly for an automotive vehicle, the sensor assembly configured for sensing an impact, the sensor assembly comprising:
-
(a) a bracket formed of sheet metal and having;
i) a first generally rectangular panel attached to a door frame of a door of an automotive vehicle; and
ii) a second generally rectangular panel attached to the first rectangular panel at a first side of the second panel, the second panel extending away from the first panel toward a door panel of the door of the automotive vehicle, the second panel disposed at about a 90°
angle relative to the first panel, the second panel including a first flange opposing a second flange for stiffening the second panel, the first and second flanges disposed respectively at a first angle and a second angle relative to the second panel, the second panel also including a third flange extending from a second side of the second panel opposite the first side of the second panel, the third flange disposed at a third angle with respect to the second panel, the third angle at least partially determining reach of the bracket; and
(b) a sensor mounted upon the first panel of the bracket, the sensor including an accelerometer, the second panel of the bracket extending beyond the sensor toward the door panel of the vehicle thereby extending the sensing area of the sensor;
wherein the second panel of the bracket only contacts the door panel if the impact deforms the door panel toward the second panel of the bracket such that the second panel can transmit an acceleration or deceleration caused by the door panel contacting the second panel to the sensor. - View Dependent Claims (9, 10, 11)
