- - - - The CREEP Factors (Design Specification)
        
        Environment
        
        Offer Padding and Break-away weak links
        
        Deformation and Break-away must remain harmless
        
        Must be free of obstacles in Flail Space (avoid impact,
        pressure, penetration, laceration)
        
        Restraint
        
        Retain Posture within Limits
        
        Restrain Cargo and other Objects
        
        Distribute Load of Acceleration on suitable Body Structure
        
        Restraints must be escapable
        
        Restrain Occupant within the Container
        
        Think seat belts, airbags, head rests
        
        Post-Crash Factors
        
        Provide for easy Escape
        
        Avoid Fire, Smoke, Submersion
        
        Preserve Occupant Consciousness / Body Function for Escape
        
        Allow Access to Emergency Helpers
        
        Container
        
        Maintain Function of the Egress Ports
        
        Anchor all Restraining Elements
        
        Maintain the Flail Space (prevent deformation, intrusion)
        
        Interface with Energy Management Elements
        
        Container must remain intact
        
        Energy Management
        
        Absorb Energy
        
        Attenuate Container Acceleration
        
        Deflect Motion of Container
        
        Think bumpers, crumble zones, airbags
  - - - Limit Acceleration
      - Keep the Container intact (avoid deformation & penetration)
      - Maintain Oxygen (Blood) supply
      - Avoid over-pressure
- - - - mass
      - strength
      - dimensions (lengths)
