Hip inflatable protection device
First Claim
1. A protective system worn outside clothing for preventing injuries to the user as a result of falls, the system comprising:
- an elongated inflatable airbag assembly having upper and lower parts folded into pleats and adapted to cover the hips, pelvis, buttocks, and coccyx areas of the user'"'"'s body when in an inflated state;
a belt for supporting said airbag assembly around the waist of a user, said belt defining a cavity and said airbag assembly being substantially within said cavity when in an uninflated state;
a sensor for detecting acceleration and a sensor for detecting angular movement, said sensors for producing a signal indicative of a predetermined combination of acceleration and angular movement, the predetermined combination corresponding to a fall; and
a gas source adapted to release gas into said airbag assembly in response to said signal.

Abstract
The invention is a self-contained protective device/system designed to protect the hips, pelvis, buttocks, and coccyx areas of the user. The device may be worn outside of the clothing. Because it is small in size and lightweight, it may be easily put on and removed and does not interfere with body movements. It contains the following components: an inflatable air bag folded into pleats, a battery, a gas cartridge, sensors to determine angular motion and acceleration, a triggering/valve mechanism to release the gas and a relief valve. When the user falls, the sensors automatically release gas from the cartridge and inflate the airbag assembly, forcing the folded pleats to fully cover said areas of the user'"'"'s body. After use the relief valve is opened to release air from the airbag assembly, the pleats are reinserted into the system and the invention is ready for reuse after the spent cartridge is replaced. The invention is superior to prior art because of its automatic deployment, compact size, light weight, ease of use and reusability. In this embodiment it will afford much needed protection to the elderly and infirm.

10. A protective system for preventing injuries to at least one of the hips, pelvis, buttocks and coccyx of a user, the system comprising:
-
an elongate inflatable airbag assembly; a belt for supporting said airbag assembly around the waist of a user, said belt having a cavity associated therewith and said airbag assembly being housed substantially within said cavity when uninflated; sensing means for sensing acceleration and angular movement and for producing a signal indicative of a predetermined combination of acceleration and angular movement, the predetermined combination corresponding to a fall; and inflating means for inflating said airbag assembly to an expanded configuration in response to said signal. - View Dependent Claims (11, 12, 13, 14)

15. A protective system for protecting at least a portion of the human body, comprising:
-
a belt adapted to be secured around the waist of a wearer, the belt defining a predetermined width measured along the spine of the user; an inflatable airbag associated with the belt and adapted to be stored in a folded, uninflated state, the airbag defining a width measured along the spine of the user substantially equal to the width of the belt when the airbag is in the folded, uninflated state; sensing means for sensing acceleration and angular movement and for producing a signal indicative of a predetermined combination of acceleration and angular movement, the predetermined combination corresponding to a fall; and inflating means, associated with the belt, for inflating the airbag to an unfolded, inflated state in response to said signal, the air bag defining a width substantially greater that the width of the belt when in the unfolded, inflated state.
