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 helmet with an airbag assembly coupled to the shell of the helmet. The airbag assembly includes an airbag and an inflation device. The inflation device is configured to at least partially inflate the airbag upon deployment of the airbag assembly. The helmet also includes a s processing circuit disposed at least partially within the shell. The processing circuit is configured to receive helmet data regarding a second helmet, transmit deployment data regarding inflation of the airbag assembly, and control operation of the inflation device to inflate the airbag based on the helmet data.

The invention relates to an inflatable airbag (1) for the protection of a person comprising a flexible sheath (10) which comprises at least two fingerlike extensions (11), wherein the flexible sheath (10) delimits a closed gas expansion chamber by the fingerlike extensions (11). The invention excels by the fact that the fingerlike extensions (11) are connected, especially stitched, glued or welded, to each other so that in an inflated state the airbag (1) takes a three-dimensional shape. The invention further relates to an airbag module, a vehicle occupant restraint system as well as vehicle parts comprising such airbag.

An airbag deployment system includes a helmet, a torso protection assembly, and an airbag assembly. The airbag assembly is coupled to one of the helmet and the torso protection assembly and includes an airbag, an inflation device configured to inflate the airbag, and a first coupling device. The first coupling device is configured to couple to a second coupling device provided on the other of the helmet and the torso protection assembly upon inflation of the airbag. The coupling resists relative movement between the helmet and the torso protection assembly.

A helmet with wireless sensor system for monitoring of surrounding objects. The helmet with wireless sensor system comprises a wireless sensor transceiver with a number of patch antennas to transmit a particular signal and receive reflected signals from surrounding objects; a processing unit located in a main shoulder pad communicating through radio frequency with a helmet uses the information from reflected signal received by wireless sensor transceiver to calculate the speed, distance, and direction of the object to determine when and where an impact will occur; and a number of inflatable/deflatable pads installed on the helmet and external to the helmet that will be activated prior to an impact.

A protection device for the head of a human comprising an airbag having an outer skin enclosing a gas space. The inflated airbag of this protection device covers at least a part of the face of said human.

A wearable protection device, including a protective helmet with at least one first inflatable chamber for moving between a rest condition in a deflated status and an operating condition in an inflated status, and a wearable element including an inflator unit and an activation system to trigger the inflator unit if a danger situation for the user of the wearable protection device is identified. The wearable element includes at least one second inflatable chamber for moving between a rest condition when in deflated status and an operating condition when in inflated status. The inflator unit is connected to the first inflatable chamber and/or the second inflatable chamber. The inflator unit inflates the first inflatable chamber and/or the second inflatable chamber in the operating condition when a danger situation for the user of the wearable protection device is identified by the activation system.

A protective suit comprising: a head portion comprising a fluid-filled head portion chamber; a neck portion releasably secured to the head portion and comprising a neck portion chamber, wherein the fluid-filled head portion chamber is in fluid communication with the neck portion chamber; and a torso portion releasably secured to the neck portion and comprising a fluid-filled torso portion chamber, wherein the fluid-filled torso portion chamber is in fluid communication with the neck portion chamber; and wherein the head portion is configured to be disposed on a head of the wearer, the neck portion is configured to be disposed in an arcuate manner around a neck of the wearer, and the torso portion is configured to be disposed on a torso of the wearer, such that when a force of an impact is received on the head portion, fluid from the fluid-filled head portion chamber is transferred into the neck portion chamber to support the neck of the wearer against translational and rotational forces imparted to the wearer, and when a force of an impact is received on the torso portion, fluid from the fluid-filled torso portion chamber is transferred to the neck portion chamber to support the neck of the wearer against translational and rotational forces imparted to the wearer.

The present invention is a helmet system that reduces concussions by damping rotational force transmitted to a helmet user. The helmet has an exterior shell and an internal body that moves independently from the exterior shell. At least one magnetic source on the exterior shell's interior has a dipole directed axially at the internal body. At least one magnetic source on the internal body has a dipole aligned with the same axis, directed at the exterior shell. In a resting state magnetic sources generate a weak magnetic field. When an impact rotates the exterior shell, it moves off the initial alignment and closer to the internal body. The previously aligned magnetic sources torque. The magnetic source on the internal body torques in the opposite direction of the rotation, as do all initially aligned magnetic sources impacted. Angular momentum is displaced, diffused, offset, damping rotational force transmitted to a helmet user.
