Acceleration protective trousers or G-protective trousers are double-walled forming airtight compartments. The trousers include an air-permeable, tear-resistant, fire-resistant and low-stretch synthetic textile material, and the trousers are provided with compartments which can be inflated into a circular cross-section. These compartments act as muscles by two opposite edges being pulled together and the adjacent pieces of textile material being stretched. These compartments extend along the trouser legs and are connected at the upper end of the trouser legs. The compartments on the outer sides of the trouser legs extend upwards from the groins and terminate in a bag-like bladder towards the lower abdomen. On the rear side of the trousers they communicate with one another via a connecting channel. A coccyx channel branches off downwards and extends towards the crotch. The compartments communicate via at least one hose with raccord with an automatically meterable compressed air supply.

The invention relates to a passenger oxygen mask for the emergency supply of oxygen in an aircraft, with a breathing bag which is provided on the entry side with a tube for the oxygen supply, wherein the tube and the breathing bag consist of polyurethane. The invention further relates to a breathing bag, with which a flow indicator is integrated into the connection piece.

A protective aviation garment is designed to protect a crewmember during flight. The garment includes a bladder layer which retains a pressurized fluid and applies pressure to the user. The bladder layer is semi-permeable, being impermeable to both oxygen and nitrogen and permeable to water vapor. A first fluid tube is formed as part of the bladder layer to deliver the pressurized fluid to the interior of the bladder layer. A cover layer is formed from a fire-retardant fabric surrounding the exterior of the bladder layer. The cover layer is sealed around the first fluid tube and allows the first fluid tube to pass therethrough. The thigh seals are configured to seal the bladder layer to the user such that the bladder layer forms a lower volume and an upper volume. The first fluid tube delivers the first pressurized fluid to the lower volume.

A system may include a vehicle. The vehicle may include an array of haptic devices. The system may further include at least one processor configured to: determine a location of an object or occurrence relative to the user; based at least on the location of the object or occurrence relative to the user, select at least one haptic device of the array of haptic devices to be driven and function as a directional haptic alert to the user, wherein the directional haptic alert is indicative of a direction from the user toward the object or occurrence; and output at least one command to cause a driving of the selected at least one haptic device, wherein the driving of the selected at least one haptic device is perceivable by the user as the directional haptic alert.

Aspects herein provide for an apparel item having an integrated parachute structure and a set of intake ducts. The parachute structure is configured to transition from a first slack state to a second inflated state subsequent to air entering the set of intake ducts incident to ground locomotion of the wearer thereby increasing air resistance to wearer movement.
