Abstract

A passenger and cargo area fire safety system for a vehicle actuated by a collision comprising a series of impact sensors and a series of fire extinguishing gel injector nozzles placed around the perimeter of the vehicle including the passenger compartment and the trunk compartment. The gel is stored as a dry, powdered concentrate which when expelled and contacting air becomes a semi-solid gel protecting the passengers from injury and the cargo from damage.

Claims

1. A vehicle and collision safety system comprising:

a vehicle including perimeter regions for a passenger compartment and a cargo compartment;

a collision safety system comprising a plurality of impact sensors in an electrical circuit and injector nozzles in a conduit line positioned along the perimeter regions; and

a chemical producing conduit circuit in communication with said electrical circuit and communicating with said conduit line, said chemical producing conduit circuit containing a pressurized gaseous propellent containing tank, a foam gel containing tank and a mixing tank, wherein the gaseous propellent and the foam gel are combined in the mixing tank;

whereby a predetermined shock detected by at least one of the plurality of impact sensors causes the pressurized gas containing tank to release the gaseous propellant and the foam gel containing tank to release the foam gel to proceed to the mixing tank and into the conduit line containing the injector nozzles for injection into the passenger and cargo compartments to provide a protective and resilient foam gel coating in the vicinity of the injector nozzles.

2. The vehicle and collision safety system according to claim 1, wherein the plurality of impact sensors and injector nozzles are positioned in a roof of the passenger and cargo compartments.

3. The vehicle and collision safety system according to claim 1, wherein the chemical producing conduit circuit is positioned below the floor of the cargo compartment.

4. The vehicle and collision safety system according to claim 1, wherein the injector nozzles are individually configured as a narrow circular nozzle opening containing a plurality of apertures with a wider circular base and based on a flat circular flange.

5. The vehicle and collision safety system according to claim 1, wherein the plurality of impact sensors are individually configured as pressure sensitive circular bodies.
