Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
166 words
A safety device for vehicles having a frame, bumper bar and brake pedal including, spring cushion means movably mounting said bumper bar to said frame, a brake solenoid operable to actuate said brake pedal, displaceable contact means carried by the forward portion of said bumper bar, switch means operable upon displacement of said contact means, a bumper solenoid disposed between said frame and bumper bar, said bumper solenoid including a coil having a core provided with a magnetic portion normally disposed within the coil and forward projecting portion engageable with the rear of said bumper bar, an electrically energized circuit joining said switch means, brake solenoid and bumper solenoid whereby, upon rearward displacement of said contact means said switch means is closed to energize said circuit and concurrently actuate said brake solenoid to operate said brake pedal and actuate said bumper solenoid to resist displacement of said bumper bar rearwardly as said bumper solenoid magnetic core portion is electrically urged to remain within its respective core.
Claim 2
Dependent Claim
166 words
A safety device for vehicles having a frame, bumper bar and brake pedal including, spring cushion means movably mounting said bumper bar to said frame, a brake solenoid operable to actuate said brake pedal, displaceable contact means carried by the forward portion of said bumper bar, switch means operable upon displacement of said contact means, a bumper solenoid disposed between said frame and bumper bar, said bumper solenoid including a coil having a core provided with a magnetic portion normally disposed within the coil and forward projecting portion engageable with the rear of said bumper bar, an electrically energized circuit joining said switch means, brake solenoid and bumper solenoid whereby, upon rearward displacement of said contact means said switch means is closed to energize said circuit and concurrently actuate said brake solenoid to operate said brake pedal and actuate said bumper solenoid to resist displacement of said bumper bar rearwardly as said bumper solenoid magnetic core portion is electrically urged to remain within its respective core.
Claim 3
Dependent Claim
28 words
A safety device for vehicLes according to claim 1 wherein, said contact means comprises a bar overlying at least a portion of the face of said bumper bar.
Claim 4
Dependent Claim
42 words
A safety device for vehicles according to claim 2 wherein, said switch means includes a movable switch element engageable with said contact bar, and spring means normally urging said switch element forwardly to maintain said contact bar spaced from said bumper bar.
Claim 5
Dependent Claim
48 words
A safety device for vehicles according to claim 3 wherein, said switch means includes two contacts, said movable switch element provided with a switch plate normally engaging one of said contacts but displaceable rearwardly to additionally engage said other contact to close said circuit at said switch means.
Claim 6
Dependent Claim
53 words
A safety device for vehicles according to claim 1 wherein, said brake solenoid includes a core having a non-magnetic section normally substantially fully disposed within said solenoid and an adjacent portion of said core comprises a magnetic section normally having a significant area of its body projecting from said solenoid when not activated.
Claim 7
Dependent Claim
24 words
A safety device for vehicles according to claim 1 including, additional switch means in said circuit which when opened deactivates only said brake solenoid.
