Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 178 words
A vehicle safety system comprising: a seat belt having an inflatable section thereof which is adapted to be positioned about a wearer when the wearer is seated in a seat in the vehicle, said inflatable section being in the form of a hollow tube normally longitudinally folded and maintained in an uninflated state, frangible fastening means normally maintaining said inflatable section in said uninflated state, said fastening means being breakable in response to inflation to permit unfolding of said inflatable section; sensing means responsive to a preselected condition of the vehicle; inflating means capable of inflating said inflatable section; electrical connecting means connecting said inflating means and said sensing means; said inflating means being responsive to actuation of said sensing means and capable of inflating said inflatable section prior to any substantial forward motion of the wearer relative to his seat as a result of said preselected condition; and said inflatable section upon inflation, expanding radially outward towards said wearer and contracting longitudinally, whereby said wearer is pressed rearwardly in his seat prior to any substantial forward motion.
Claim 2
Dependent Claim 178 words
