Abstract

The invention relates to a safety system 10 for motor-driven vehicles 12 comprising at least one door 14. The system 10 comprises a movement detector 161, . . . , 16N at each door 14 to detect movement within a predetermined area 181, . . . , 18N near said door 14 and/or a movement detector 20 at the rear of the vehicle 12 to detect movement within a predetermined area 22 behind the vehicle 12, and wherein each movement detector 161, . . . , 16N, 20 is also connected to an indicator 261, . . . , 26N, 26B arranged in conjunction with the driver'"'"'s seat 24 in the vehicle 12 in order to attract the attention of the driver upon detection of movement within said area/areas 181, . . . , 18N, 22.

Claims

1. A safety system (10) for motor-driven vehicles (12) comprising at least one door (14), characterized in that the system (10) comprises a movement detector (16₁, . . . , 16_N) at each door (14) to detect movement within a predetermined area (18₁, . . . , 18_N) near said door (14) and/or a movement detector (20) at the rear of the vehicle (12) to detect movement within a predetermined area (22) behind the vehicle (12), and in that each movement detector (16₁, . . . , 16_N, 20) is connected to an indicator (26₁, . . . , 26_N, 26_B) in conjunction with the rear-view mirror (30) of the vehicle (12) in order to attract the attention of the driver upon detection of movement within said area/areas (18₁, . . . , 18_N, 22) to enable the driver alone to reach a decision.

2. A safety system (10) for motor-driven vehicles (12) as claimed in claim 1, characterized in that each movement detector (16₁, . . . , 16_N, 20) consists of an IR movement detector.

3. A safety system (10) for motor-driven vehicles (12) as claimed in claim 1, characterized in that each movement detector (16₁, . . . , 16_N, 20) consists of a movement detector of laser type.

4. A safety system (10) for motor-driven vehicles (12) as claimed in any one of claims 1-3, characterized in that each indicator (26₁, . . . , 26_N, 26_B) consists of a lamp, each lamp emitting a different-coloured light.

5. A safety system (10) for motor-driven vehicles (12) as claimed in claim 4, characterized in that the lamps are fitted close to or in the rear-view mirror (30), and in that each lamp lights up when the relevant movement detector (16₁, . . . , 16_N, 20) detects movement within said areas (18₁, . . . , 18_N, 22), and is extinguished with a predetermined time delay after the relevant movement detector (16₁, . . . , 16_N, 20) no longer detects movement within said areas (18₁, . . . , 18_N, 22).

6. A safety system (10) for motor-driven vehicles (12) as claimed in any one of claims 1-3, characterized in that each indicator (26₁, . . . , 26_N, 26_B) consists of a sound alarm, each sound alarm emitting an audible signal when the relevant movement detector (16₁, . . . , 16_N, 20) detects movement within said areas (18₁, . . . , 18_N, 22), and ceasing to emit audible signals with a predetermined time delay after the relevant movement detector (16₁, . . . , 16_N, 20) no longer detects movement within said areas (18₁, . . . , 18_N, 22).

7. A safety system (10) for motor-driven vehicles (12) as claimed in claim 5 or claim 6, characterized in that said time delay is approximately 3-4 seconds.

8. A safety system (10) for motor-driven vehicles (12) as claimed in any one of claims 1-7, characterized in that the movement detectors (16₁, . . . , 16_N, 20) at the doors (14) are arranged above the doors (14), and in that said areas (18₁, . . . , 18_N), at ground level comprise at least the width (I) of the door (14) and approximately 1-2 metre out from the vehicle.

9. A safety system (10) for motor-driven vehicles (12) as claimed in any one of claims 1-8, characterized in that the system (10) is powered via the electrical system of the vehicle, and in that the safety system (10) is activated when the vehicle (12) is started and the indicator(s) (26₁, . . . , 26_N, 26_B) is/are activated for a predetermined period of time to check that the system (10) is functioning.
