More specifically, at least some of the disclosed embodiments are concerned with a backpack-integrated whole-body airbag system, including wearable inflatable lower body/lower extremity garments to provide whole- body flotation during avalanche incidents and/or potentially catastrophic high-impact crashes.
  • the deployed airbag provides 2 functions: it may help the wearer to stay afloat atop the cascading avalanche debris by utilizing the buoyancy factor of the airbag (see Fig. 1), and the airbag may provide some degree of physical protection to the wearer, though such protection is limited to, at most, the head, neck, shoulders and upper torso, of the user.
  • disclosed embodiments are concerned with a whole-body airbag system that may provide consistent protection not just to the caput, shoulders and upper torso, but comprehensive protection to the entire body, including the lower torso, pelvic region and lower extremities. This is accomplished by way of a selectively inflatable lower body garment that, depending upon the embodiment, may or may not, be integrated together with an upper body protection/flotation system. Such embodiments may optimize short and long-term survivability in avalanche situations, high-impact falls, or other traumatic events.
  • Example embodiments of the invention may provide any one or more of the various features and elements disclosed herein. Such features and elements include, but are not limited, those discussed immediately below.
  • the disclosed whole-body airbag system may be configured in a variety of ways and configurations (as disclosed in Figures 3-8, discussed below).
  • Example embodiments of the whole-body inflatable airbag system may include any one or more of the following components and technologies:

  • lower body garment made from any one or more of a variety of textiles and materials, with separate airbag compartments on the lateral and/or medial aspects of the lower extremities above and below the knee;
  • manual deployment system utilizing a mechanical draw cord approach or comparable system/device, such as an actuating push button, positioned within the whole-body inflatable airbag system for easy access by the wearer;
  • automatic deployment system utilizing appropriate accident detection/sensing technologies (e.g., motion sensors, spatial orientation sensors, directional velocity sensors, angular velocity sensors (i.e., gyrometer sensors), rotation sensors, shock sensors, collision sensors, accelerometers, etc.);
  • appropriate accident detection/sensing technologies e.g., motion sensors, spatial orientation sensors, directional velocity sensors, angular velocity sensors (i.e., gyrometer sensors), rotation sensors, shock sensors, collision sensors, accelerometers, etc.
  • threshold parameters for automatic deployment of the airbag system will be determined and programmed into a processor that is integrated in the airbag system;
  • automatic deployment of the airbag system can also be effected by rapid separation of the rider from the vehicle upon which the user is riding (e.g., skis, snowboard or snowmobile), with such a tethering mechanism automatically signaling the actuator to deploy the airbag system; 9. all, or any of the above, accident detection/sensing or any other technologies known by one of skill in the art may be housed in the sensory unit housed within any portion of the backpack;
  • the airbag-containing garments will allow deployment of each separate airbag through a lateral window or slit secured via a common hook-and-loop fastener

Abstract

La présente invention concerne, dans un exemple, un système comprenant un système de gonflage de coussin de sécurité gonflable, un système de commande couplé de manière fonctionnelle au système de gonflage de coussin de sécurité gonflable, et un pantalon et/ou d'autres vêtements de corps inférieur qui comprennent un ou plusieurs coussins d'air configurés pour être couplés de manière amovible au système de gonflage de coussin de sécurité gonflable. Le système de gonflage de coussin de sécurité gonflable peut être actionné manuellement par l'utilisateur, et/ou automatiquement sur la base d'une entrée provenant d'un ou de plusieurs capteurs. Les coussins de sécurité gonflables peuvent être gonflés par un gaz comprimé, ou par un flux d'air provenant d'un mécanisme tel qu'un ventilateur.
