An airbag inflation system includes a processing circuit configured to receive object data including positional data regarding an object and at least one of a relative velocity and a relative acceleration of the object relative to a first helmet and control operation of an inflation device to inflate an airbag based on the object data.

A protective device includes an airbag assembly configured to extend at least partially around a waist or hips of an individual; a buckle attached to the airbag assembly, the buckle comprising a first buckle half, and a second buckle half, the first and second buckle halves being attachable to and detachable from one another; and an airbag actuator configured to actuate the airbag assembly. At least a portion of the airbag actuator is disposed in the first buckle half or the second buckle half.

A personal protection device for the protection of a portion of the body of a user is described. The device has an inflatable member intended to protect at least partially a zone of the body of a user. The personal protection device includes at least a first portion and a second portion. The first portion and the second portion are superimposed in a corresponding overlapping area or superimposition area. In the personal protection device the height or thickness of at least one, or each, of the first portion and the second portion is, in the overlapping area or superimposition area, smaller than the height or thickness of a remaining part of the inflatable member.

Garments made from a composite, protective fabric are disclosed. The composite fabric has textile layers placed in proximity to metallic mesh layers of woven stainless steel mesh. The metal mesh layers formed from any metal which forms suitable fibers. The textile layers are fabric formed with well-known fabric fibers selected from those including para-aramid fibers, meta-aramid fibers, ultra-high molecular weight polyethylene fibers, polyethylene terephthalate fibers, cellulose fibers, polyamide fibers, a mixture of para-aramid fibers and meta-aramid fibers, and a mixture of para-aramid fibers and carbon fibers. Forming the non-metal textile layers is by any suitable method for interlacing yarns including weaving, knitting, crocheting, knotting, or felting, or combinations thereof. The garments made using the fabric include gloves, bullet proof vests and chain-saw resistant trousers.

The present invention relates to a coupling-releasing device for airbag actuator cable 1 for vehicles having two or more wheels, said airbag being contained in a wearable jacket or coat. The coupling-releasing device of an airbag actuator cable 1 according to the present invention comprises at least one coupling unit 2,2′ adapted to be installed on board a vehicle and actuator means 4,4′,4″ operatively connected to said at least one coupling unit 2,2′ to operate said coupling unit 2,2′ between a first closing configuration adapted to retain said end of said airbag actuator cable and a second opening configuration adapted to release said end of said airbag actuator cable.

The disclosure provides neck collar devices and systems for the mitigation and prevention of traumatic brain injury, including concussion. Specifically disclosed are adjustable collars and systems, and collars having certain pressure sensing devices.

A method of inflating an airbag includes expanding a collapsed or folded frame that supports and expands the airbag. The expansion of the airbag creates a lower pressure in the interior of the airbag as compared to the exterior, which allows air to be drawn into the airbag due to the lower pressure to fill the airbag. The frame can be made from inflatable ribs, or the frame can be made from interconnecting rigid members. The inflatable ribs can be inflated using a compressed gas canister, while the frame made from rigid members can be expanded using a spring. Filling a frame made from inflatable ribs, as opposed to the airbag itself allows for a smaller compressed gas canister.
