PURPOSE:To enable automatic continuous durability test to match actual conditions by repeating the operation of engaging a reclining device and a spring-up device with respective control levers and the action of an arm whose center of turning moves to hinge position of both the devices. CONSTITUTION:As a base 6 rises with cylinders 8 and 8', an arm 11 moves to the reclining hinge position X in the center of turning. On the other hand, a control lever 1 of a reclining device is engaged and turned with a fluid motor 14 to release the locking and a seat Sb is tilted forward. Leveled with a cylinder 13, an arm 12 is turned together with the arm 11 by a fluid motor 9 to push the seat Sb backward and it is locked at the frontmost stage of the reclining. Likewise, the rotating shaft of the arm moves to the hinge position Y of a spring-up device A through a cylinder 8 and a control lever B of the device A is engaged and turned with a fluid pressure motor 18 by way of an engaging member 19. Repeating this test cycle enables automatic continuous durability test to match actual conditions. |
