This invention relates to an impact-cushioning device, which is designed to prevent injury when an occupant, confused or otherwise, falls from a height. This may be a bed or bunk, gurney or examination table. The device generally comprises an impact-reducing cushion This cushion may be air filled or of a variety of impact absorbing materials. Also provided is a means of displacing the cushion to intercept the falling individual before he or she strikes the floor. The departure of the individual from the bed is detected by signals that are generated when one or more edge pressure switches are actuated simultaneously with signals from one or more light beam sensors. Signals thus generated are processed through an electronics module and passed to a solenoid valve. When the valve opens, gas from a canister is passed to a telescoping device. This in turn displaces the cushion. Thus a protective barrier is placed between the bed occupant and the floor.
