Abstract

An arrangement in passenger vehicles, that diverts the impact energy in 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 safety devices and arrangements for head-on collision protection that protect the passenger. 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.

Claims

1. An airbag for the protection of occupants in vehicles, wherein said airbag is prefilled with air and supplementary porous filling materials, and comprising vents for exhaust, thereby enabling adjustment of the compression characteristics of the airbag.

2. An airbag as in claim 1, wherein said airbag acts as a sacrificial chamber to release airflow during compression to aircushions that are enabled to protect an occupant during impact.

3. An airbag as in claim 2, deployed with said airbag deployed such that its compression is enabled by contact with parts of the occupant with high inertial mass such that the subsequent inflation of the aircushions protect high priority anatomical regions of the occupant.

4. An airbag as in claim 3, wherein the torso of the occupant compresses the sacrificial airbag and one or both of the head and neck are protected by the at least one air cushions.

5. A vehicle with side impact protection for occupants provided with cylindrical slides (10D1 to 10D5) wherein the egress and ingress is enabled by the activation a first set of slides and impact protection for motion into the vehicle for the occupant is enabled with a second set of slides that are concentric.

6. A vehicle with side impact protection as in claim 5, wherein the first set of slides are enabled for motion with a motorized threaded shaft concentric to the cylindrical slides.

7. A vehicle with side impact protection as in claim 5, wherein the motion of the second set of slides move above structural elements of the vehicle in the center of the vehicle thereby enabling greater motion of the near side occupant during a side impact to the vehicle.
