FALLING SHOCK ABSORPTION AUXILIARY TOOL FOR HUMAN BODY

摘要

PROBLEM TO BE SOLVED: To provide a falling shock absorption auxiliary tool for a human body which improves reliability by preventing occurrence of malfunction. SOLUTION: The auxiliary tool is provided with: a plurality of falling sensors which is switched from an ON state to an OFF state when apparent gravity occurring at an inertial body is reduced; and an acceleration sensor which is switched from an OFF state to an ON state when the apparent gravity occurring at the inertial body is increased. Except for a period until a prescribed time passes after the acceleration sensor is turned on by acceleration caused by vertical movement except falling such as jumping or jumping down of a level difference by a user, when the state of detecting all the falling sensors turned into the OFF state due to falling of the user continues for the prescribed time or longer than this, an air bag is expanded. Thus, malfunction except for the case of falling is reliably prevented. COPYRIGHT: (C)2003,JPO
