Abstract

An occupant protecting system includes elongated pressure sensors. The pressure sensors is extended at least partially in at least one of a longitudinal direction of a side portion of a vehicle and a transverse direction of a front portion of the vehicle. The pressure sensors are able to detect a pressure substantially throughout the whole in the vehicular longitudinal direction which pressure is exerted on the vehicle from the exterior of the vehicle. An occupant protecting ECU drives occupant protecting means upon receipt of a detected signal from the pressure sensors.

Claims

1. An occupant protecting system comprising:

an elongated pressure sensor, at least a part of the pressure sensor being extended in at least one of a longitudinal direction of a vehicle in a side portion of the vehicle and a transverse direction of the vehicle in a front portion of the vehicle, the pressure sensor being able to detect a pressure substantially throughout the whole in a longitudinal direction of the vehicle which pressure is exerted on the vehicle from an exterior of the vehicle; and

an electric control unit which drives occupant protecting means upon receipt of a detected signal from the pressure sensor.

2. An occupant protecting system according to claim 1, wherein the pressure sensor is disposed on a side door of the vehicle.

3. An occupant protecting system according to claim 2, wherein the pressure sensor is disposed in an interior of a door.

4. An occupant protecting system according to claim 2, wherein the door has an opening weather strip for filling up a gap between the door and a body of the vehicle when the door is closed, and

the pressure sensor is disposed in an interior of the opening weather strip.

5. An occupant protecting system according to claim 2, wherein the pressure sensor is disposed at a position opposed to a side-sill of a body of the vehicle in a transverse direction of the vehicle.

6. An occupant protecting system according to claim 1, wherein the pressure sensor is disposed in a body of the vehicle.

7. An occupant protecting system according to claim 6, wherein the pressure sensor is disposed in an interior of a side-sill of the vehicle body.

8. An occupant protecting system according to claim 1, wherein the pressure sensor also serves as a pinching G-sensor for detecting pinching when the door is closed.

9. An occupant protecting system according to claim 1, wherein the pressure sensor is a touch-sensor comprising a tubular skin portion and a plurality of electrode portions disposed in an interior of the skin portion, at least two of the plural electrode portions coming into contact with each other upon deformation of the skin portion in order to detect a pressure exerted on the vehicle from the exterior of the vehicle.

10. An occupant protecting system according to claim 1, wherein the pressure sensor comprises a light emitting element, an optical fiber through which light emitted from the light emitting element passes, and a light receiving element for receiving the light having passed through the optical fiber, the optical fiber being adapted to be deformed, causing a change in loss of the light that the light receiving element receives in order to detect a pressure exerted on the vehicle from the exterior of the vehicle.

11. An occupant protecting system according to claim 1, wherein the electric control unit has a diagnostic circuit capable of trouble-shooting the pressure sensor.

12. An occupant protecting system according to claim 1, wherein the occupant protecting means is at least one of a side-airbag and a curtain-airbag.
