Easy ejector seat with skeletal crash safety beam
DC CAFCFirst Claim
1. An Air Cushion System for protecting at least one protected entity, from impact from an impacting object comprising:
- a) an impacted structure comprising said protected entity;
b) at least one sacrificial chamber located in a predetermined position within said impacted structure, such that said impact from impacting object, will compress said sacrificial chamber, said sacrificial chamber being filled with a compressible fluid at the time of said impact;
c) at least one elongate fluid path, each with first and second spaced apart end, and each comprising flow control mechanisms, that is connected to said sacrificial chamber at its first end, and filled with said compressible fluid, such that under impact to the sacrificial chamber, said fluid paths conduct a predetermined controlled volume of said compressible fluid out of said sacrificial chamber to predetermined locations away from said sacrificial chamber;
d) one or more micro-air cushions placed in predetermined locations and supported by said impacted structure, said micro-air cushions being connected to said at least one fluid path at its second end, thereby receiving predetermined controlled volumes of said compressible fluid from said fluid paths at and immediately following said impact;
thereby said sacrificial chamber inflating said micro-air cushions in predetermined directions unrelated to the direction of compression of said sacrificial chamber by transferring fluid from the first end of said at least one fluid path, to the second end of said at least one fluid path and protecting said protected entity.

Abstract
An arrangement in passenger vehicles, that diverts the impact energy in lateral or side impacts away from the passengers to the remaining mass of the vehicle thereby protecting the passengers, and in the same arrangement provides utilitarian access to the vehicle, such utilitarian access making it possible to both install multi-element contoured surround seats for passengers and the driver, and also a safety device for head-on collision protection that obviates the need for conventional seat belts and front impact airbags. An indo-skeletal structural arrangement proposed for the vehicle, provides further benefits by targeting the strength of the vehicle to protect passengers while minimizing other massive elements in the vehicle.

thereby providing a means to inflate the sacrificial chambers just prior to the impact, and thereafter providing the protection of the Air-cushion System.

-
8. An Air-cushion System as in claim 1, wherein the protected entity is the head and neck of a passenger, the impacted object is a vehicle, and the impacting object impacts the vehicle from the rear of said vehicle, and wherein said sacrificial chamber is mounted in a position that will compress on impact by the impacting object, thereby said air-cushion system protecting said passenger from whip-lash injury.
-
9. Two or more Air-cushion Systems as in claim 1, consisting of a First set of Air-cushion Systems and a Second Set of Air-cushion systems, wherein the sacrificial chambers of said Second Set of Air-cushion systems are mounted adjacent to the Micro Air-cushions of said First Set of Air-cushion Systems, such that on inflation of the Micro Air-cushions of said First Set of Air-Cushion Systems, the sacrificial chambers of said Second Set of Air-Cushion systems are compressed, thereby creating a cascaded system of Air-cushion Systems to protect one or more protected entities.
-
10. An air cushion system as in claim 1, wherein at least one of said sacrificial chamber and micro air-cushions are vented to ensure that the micro aircushions support the protected entity for a predetermined time before deflating to provide protection to the protected entity immediately after said impact.
-
11. An air cushion system as in claim 10, wherein said protected entity is an occupant of a motor vehicle and said predetermined time is the expected time of a roll over of said motor vehicle following said impact.
