Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
161 words
With an engine driven vehicle having a vehicle electrical system and an engine ignition system, an impact fire safety switch, comprising: a base member; a first current carrying support member affixed to said base member; a second current carrying support member pivotally supported to said base member in insulated and spaced relationship to said first current carrying support member, said current carrying support members being connectable in electrical series with the vehicle electrical system; biasing means normally urging said second support member towards said first support member; a current carrying inertial member normally retained betWeen said support members, said inertial member being displaced by vehicle impact; and an ignition switch means supported to said base member, said ignition switch means being connectable in electrical series with the engine ignition system, said ignition switch means being connected to said second support member and being deactivated when said second support member pivots towards said first support member when said inertial member is displaced.
Claim 2
Dependent Claim
161 words
With an engine driven vehicle having a vehicle electrical system and an engine ignition system, an impact fire safety switch, comprising: a base member; a first current carrying support member affixed to said base member; a second current carrying support member pivotally supported to said base member in insulated and spaced relationship to said first current carrying support member, said current carrying support members being connectable in electrical series with the vehicle electrical system; biasing means normally urging said second support member towards said first support member; a current carrying inertial member normally retained betWeen said support members, said inertial member being displaced by vehicle impact; and an ignition switch means supported to said base member, said ignition switch means being connectable in electrical series with the engine ignition system, said ignition switch means being connected to said second support member and being deactivated when said second support member pivots towards said first support member when said inertial member is displaced.
Claim 3
Dependent Claim
96 words
An impact fire safety switch according to claim 1 in which said ignition switch means includes: a first contact means supported on said base; and a second contact means supported in insulated relation to said second current carrying support member, said first and second contact means being connected in series with said engine ignition system and held in normal contacting relationship when said inertial members are positioned between said support members, said contact means being separated when said second support member pivots towards said first support member as said inertial member is displaced by vehicle impact.
Claim 4
Dependent Claim
17 words
An impact fire safety switch according to claim 1 including means of adjustably varying said biasing means.
Claim 5
Dependent Claim
29 words
An impact fire safety switch according to claim 1 wherein one of said current carrying support members includes integral means for accepting and connecting to a battery terminal post.
