A life-jacket with an integrated rudder for navigating water currents is shown. The jacket integrated rudder is for water navigation in swift currents and is of simple construction, using a cord with handles to steer the attached rudder by pull of cord attached handles side-to-side.

Protective equipment for protecting a person from an emergency situation is disclosed. The protective equipment has a securing device, which is portable by the person, having a securing system for protecting the person from an emergency situation. Furthermore, the protective equipment has a sensor device for detecting a dangerous situation prior to the emergency situation of the person, when the sensor device is coupled with the securing system in such a way that upon detection of the dangerous situation of the person, the sensor device automatically sets the securing system in a securing state for protecting the person.

An inflatable flotation device having a reaction chamber with reactants that generate gas when mixed, said reactants being separated by a barrier assembly; an activating mechanism adapted to remove or puncture the barrier assembly such that said reactants mix; and an inflatable compartment fluidly connected to the reaction chamber by means of a pressure sensitive passageway, adapted to open only when the pressure of the gas in said reaction chamber exceeds a predetermined threshold. This ensures that most of the reactants are used up to generate gas before the gas enters the inflatable chamber, thus preventing scattering of the reactants. Some implementations have a reaction chamber without a barrier assembly, comprising reactants that generate gas when mixed with water and an activating mechanism adapted to expose the reactants to water. A variety of manual or automatic mechanisms may be employed to activate the reaction and inflate the device.

An inflatable survival vest includes an inflatable bladder having an inflation inlet through which a gas is input to inflate the bladder. The bladder is configured in the shape of a vest. The bladder has a plurality of parallel seams that divide the bladder into tubular channels. The tubular channels cause the vest to have a wavy outwardly facing surface with crests and troughs and a wavy inwardly facing surface with crests and troughs. An inner air chamber is positioned along the inwardly facing surface of the bladder. A shell with limited stretch-ability overlies the inflatable bladder, thereby limiting outward expansion of the bladder such that the bladder is adapted to expand inwardly pressing the inner air chamber against a body of a person wearing the bladder.

A self-inflating personal flotation device (SIPFD) configured to be worn by a wearer and aid the wearer automatically. The SIPFD may communicate with a global communication network and pressurized gas cartridge assembly based on a triggering event. The SIPFD may have a wearable data transmitter of a heartbeat device; a water depth device; and a geolocation device. The SIPFD may have a neck inflation device and a torso inflation device both connected to the pressurized gas cartridge assembly to enable the pressurized gas cartridge to inflate the neck and torso inflation devices when prompted. The prompt may be automatic or on request and be performed using an actuator mechanically communicating with the pressurized gas cartridge assembly to: (i) inflate the neck and torso inflation devices; and (ii) deflate the neck and torso inflation devices associated with a wearer.

The present disclosure provides a swimming auxiliary equipment, including an auxiliary equipment main body, a strap, a connecting belt and two arm jackets, wherein two sides of the auxiliary equipment main body are tied to the waist of a swimmer through the strap, and the arm jackets are connected to the auxiliary equipment main body through the connecting belt; the auxiliary equipment main body includes a first air bag, a cavity is arranged inside a waterproof layer, the first air bag is arranged in the cavity, and a pressure sensor is arranged on an inner wall of the auxiliary equipment main body; and the auxiliary equipment main body includes an expansion bin arranged in the cavity and a net structure with a plurality of connected layers, a priming device is arranged on the net structure, and the priming device is arranged in the cavity and connected to the pressure sensor.

In order to provide a small life jacket that is unlikely to obstruct movement of a wearer, a life jacket includes: a float member that changes from an uninflated state to an inflated state with gas being supplied to an internal portion thereof; a cover that covers the float member in the uninflated state; a connecting member and a waist belt as a wearable member that is to be worn by a wearer; a guide member that is linked to the connecting member and the waist belt; and a slidable member that is linked to the float member and that slides along the guide member.

A personal flotation device may include a chest portion, an abdominal portion, and a connecting portion positioned between the chest portion and the abdominal portion. The width of the connecting portion may be smaller than the width of both the chest portion and the abdominal portion. The connecting portion may extend only from a center region of the chest portion. The chest portion, abdominal portion and connecting portion may be arranged to together form an approximately I-shaped portion. The personal flotation device may be secured to a garment.
