Abstract
A system for providing wearable inflatable impact protection, the system having a wearable airbag garment, a first airbag chamber connected to the wearable airbag garment, an airbag igniter connected to the first airbag chamber, a controller connected to the airbag igniter, a sensor array connected to the controller, and a power source connected to the controller. The sensor array detects at least one of use, movement, location, and acceleration of the wearable airbag garment. The controller triggers the airbag igniter to inflate the first airbag chamber in a case where the controller determines at least one of a set of performance criteria has been exceeded.
Claims12
A system for providing wearable inflatable impact protection, the system comprising:
- a wearable airbag garment;
- a first airbag chamber connected to the wearable airbag garment;
- a second airbag chamber;
- an airbag igniter connected to the first airbag chamber;
- a controller connected to the airbag igniter;
- communication link circuitry configured to link the controller and a vehicle control area network (CAN);
- at least one proportioning valve disposed between the first airbag chamber and the second airbag chamber, the at least one proportioning valve controlled by the controller;
- and
- a sensor array connected to the controller;
- wherein
- the sensor array detects at least one of use, movement, location, and acceleration of the wearable airbag garment,
- the controller triggers the airbag igniter to inflate the first airbag chamber in a case where the controller determines at least one of a set of performance criteria has been exceeded, and
- the controller, in response to crash data received from the vehicle CAN, adjusts the proportion of a gas pressure directed to the second airbag chamber via the at least one proportioning valve as the airbag igniter inflates the first airbag chamber.
A system for providing wearable inflatable impact protection, the system comprising:
- a wearable airbag garment;
- a first airbag chamber connected to the wearable airbag garment;
- a second airbag chamber;
- an airbag igniter connected to the first airbag chamber;
- control means for controlling the airbag igniter;
- communication means linking the control means and a vehicle control area network (CAN);
- at least one proportioning valve disposed between the first airbag chamber and the second airbag chamber, the at least one proportioning valve controlled by the control means;
- and
- a sensor array connected to the control means;
- wherein
- the sensor array detects at least one of use, movement, location, and acceleration of the wearable airbag garment,
- the control means triggers the airbag igniter to inflate the first airbag chamber in a case where the control means determines at least one of a set of performance criteria has been exceeded, and
- the control means, in response to crash data received from the vehicle CAN, adjusts the proportion of a gas pressure directed to the second airbag chamber via the at least one proportioning valve as the airbag igniter inflates the first airbag chamber.
