Vehicle impact testing device
First Claim
1. A vehicle crash test apparatus comprising:
- a road surface for a test vehicle to travel on;
a barrier disposed at one end of the road surface;
a left-right pair of guide rails provided in the length direction in the proximity of the road surface; and
a towing device suspended movably between the left and right guide rails, to lead a test vehicle on the road surface to the barrier, so that the test vehicle is pulled to the proximity of the barrier using the towing device, and part-way through the pulling the test vehicle is disconnected from the towing device and the test vehicle is caused to collide with the barrier.

Abstract
A vehicle impact testing device (10, 100, 500) is provided with a towing device (16, 116, 516) for running a test car (11) along a running road surface (12, 112, 521) to collide with a barrier (13, 113, 513). The towing device is movably suspended from a pair of guide rails (26, 126, 514) received in a recess (15, 115, 523) formed below the running road surface. The towing device is disposed between the guide rails, thereby making effective use of the space between the guide rails. Further, the towing device is disposed at a position below the running road surface, so that it does not interfere with the running of the test car.

3. A vehicle crash test apparatus comprising:
-
a road surface for a test vehicle to travel on;
a barrier disposed at one end of the road surface;
a towing device disposed below the road surface;
a guide rail disposed below the road surface, for guiding the towing device to the barrier; and
a braking device disposed below the road surface, for stopping the towing device, so that the test vehicle is pulled to the proximity of the barrier using the towing device, and when the test vehicle is disconnected from the towing device at a position a predetermined distance in front of the barrier to cause the test vehicle to collide with the barrier, the towing device is stopped with the braking device. - View Dependent Claims (4, 5)

6. A vehicle crash test apparatus comprising:
-
a road surface for a test vehicle to travel on;
a barrier disposed at one end of the road surface;
a towing device for pulling the test vehicle;
a hook provided on the towing device so that it projects above the road surface, to connect the towing device and the test vehicle; and
a hook projection clearing device for clearing the projecting state of the hook when the towing device has reached a position a predetermined distance in front of the barrier, so that the test vehicle is pulled to the proximity of the barrier using the towing device, and part-way through this pulling the test vehicle is disconnected from the towing device and so caused to collide with the barrier. - View Dependent Claims (7, 8)
