Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
166 words
A vehicle safety system for protecting the occupant of a vehicle in the event of an accident, said system comprising: 1. an inflatable strap member comprising a diagonal safety belt adapted to be secured at its ends and to extend across an occupant of the vehicle so as to restrain the occupant in position in the event of an accident; 2. an inflatable head bag mounted on said diagonal safety belt at a position adjacent one side of the head position, said inflatable head bag being formed as a separate unit and being adapted to be normally in the collapsed condition; 3. a source of compressed gas; 4. valve means for controlling the supply of gas from said source, said valve means being arranged to respond to vehicle impact to release gas from said source; 5. a first connecting passage connecting said source of gas to said inflatable head bag; and 6. a second connecting passage connecting said source of gas to said inflatable strap member.
Claim 2
Dependent Claim
