Abstract: An airbag device for the body instantaneously activates an airbag without malfunctions. When an absolute value of an angular velocity detected by an angular velocity sensor exceeds a predetermined angular velocity value, angular velocity values are integrated from a most recent detected value to an oldest value within a predetermined time period, and if an absolute value of a resultant value of integral exceeds a predetermined value and an acceleration detected by an acceleration sensor is smaller than a predetermined acceleration, the airbag is inflated. Based on the value of the integral of the angular velocities, a case in which an angular velocity gradually increases is distinguished from a case in which an angular velocity momentarily increases, so the airbag device effectively prevents malfunctions caused by an action other than falling over. Additionally, because it is unnecessary to intentionally delay determination to prevent malfunctions, the airbag can instantaneously be inflated.

Abstract: A harness type safety belt absorbs dropping shocks to a user who accidentally falls from an elevated position. If the user fails to apply a rope hook to a life line and falls from the elevated position, an air bag in a mounting body inflates to absorb the dropping shock to reduce the dropping impact applied to the user. If the user falls with the rope hook connected to the life line, the rope suspends the user. The body of the user is supported by a waist belt, shoulder belts and thigh belts. Therefore a tension applied by the rope to the body of the user is dispersed to each of the belts so the body of the user is stably supported.

Abstract: A falling shock absorbing apparatus for a wheelchair is provided capable of absorbing shock to the user in the case of falling of a wheelchair. In other words, the falling shock absorbing apparatus for wheelchair of the present invention includes an inflatable air bag for covering a predetermined parts of the wheelchair user when inflating, an inflation apparatus for inflating the air bag, an inclination detecting apparatus for detecting inclination of the wheelchair relative to the surface upon which the wheelchair is moved, and a controller for activating the inflation apparatus to inflate the air bag when inclination of the wheelchair is detected by the inclination detecting apparatus. Thus, the air bag inflates to cover the predetermined parts of the wheelchair user when the wheelchair is tilted.

Abstract: The present invention provides a shock absorbing aid for a human body ensuring an effective alleviation of a shock to the human body. In the present invention, air bags are inflated upon a detection of separation of a wearer's body from an object of contact, such as when the wearer has fallen from an aerial place, thereby making it possible to absorb a shock to the human body with the aid of the air bags even when the wearer has directly dropped on the ground or the like.
