A safety, rescue, and recovery device that compressively secures to a limb of a user when inflated. The device can be easily adjusted to be negatively buoyant, neutrally buoyant, or positively buoyant before inflation depending on whether the application is safety, rescue, or recovery. The device may also be integrated into an article of clothing for certain applications. An elongated handle is attached to the device to provide a sliding attachment point for a rescue rope that automatically reduces torque applied to the limb of the user. Consequently, a rescue force applied to the rescue rope can act at a variety of angles along an arc relative to the device.

A life preserver locator system for assisting in locating and rescuing persons located in body of water. The life preserver locator system includes a water permeable envelope attachable to a life preserving aid and having a deployable water-activated signal assembly. In one embodiment, the deployable water-activated signal assembly includes a water-activated gas inflator mechanism that on exposure to water, such as saltwater, automatically actuates to inflate a balloon. The balloon deploys from the envelope into the air on a cable attached to the life preserver locator system allowing establishment of a line of sight from a person in the water and a rescue vessel to the balloon. In one embodiment, a light emitting device, such as strobe light, on the balloon automatically activates to emit light, to assist the person in the water in locating the life preserving aid. When the person reaches the life preserving aid, the person can activate a switch on the water-activated signal assembly changing the appearance of the emitted light.

Embodiments of the present disclosure relate generally to inflation systems. Specific embodiments relate to inflation systems that use a mixed flow compressor to deliver a diagonal airflow for inflation. The inflation systems disclosed do not require the use of compressed gas, but can use a battery-powered or otherwise electric motor for generating airflow from ambient air. Particular embodiments may find use in connection with inflating evacuation slides or life rafts on board a passenger transportation vehicle, such as an aircraft or marine vessel. Other embodiments may be used for inflating shelters, life vests, or any other safety device that requires a rapid inflation.

The present invention relates to a portable airbag system for people, comprising a support intended to be worn by a user, and an airbag device comprising at least one inflatable bag having at least one central part (2a) designed to be disposed behind the head of a user after triggering. The airbag device is assembled in a cover or bag part forming a unit configured to be disposed entirely on the back of a user before deploying, the airbag device being fixed by means of a fixing device such as to be removable and separable from the support.
