Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
56 words
In a vehicle having an internal combustion driving engine, a manually operated transmission connectable to the driving engine, and a shift lever for controlling the manually operable transmission and having a neutral position, the improvement comprising a control device responsive to placing of the shift lever in the neutral position to cut off the driving engine.
Claim 2
Dependent Claim
56 words
In a vehicle having an internal combustion driving engine, a manually operated transmission connectable to the driving engine, and a shift lever for controlling the manually operable transmission and having a neutral position, the improvement comprising a control device responsive to placing of the shift lever in the neutral position to cut off the driving engine.
Claim 3
Dependent Claim
37 words
A vehicle as claimed in claim 1 further including a time-delay element which permits cut off of the driving engine only after a predetermined period of time has elapsed since the shift lever entered the neutral position.
Claim 4
Dependent Claim
23 words
A vehicle as claimed in claim 1 or 2, wherein that the control device is actuated as a function of the engine temperature.
Claim 5
Dependent Claim
37 words
A vehicle as claimed in claim 3 further including a temperature switch whose operation is dependent upon the engine temperature, said switch releasing the control device for actuation only when a predefined engine temperature has been exceeded.
Claim 6
Dependent Claim
28 words
A vehicle as claimed in claim 1 or 2, further including a manually-actuable control switch for preventing actuation of the control device until the control switch is actuated.
Claim 7
Dependent Claim
35 words
A vehicle as claimed in claim 1, wherein the control device is rendered in such a manner that on displacement of the lever out of the neutral position, starting of the driving engine is initiated.
Claim 8
Dependent Claim
50 words
A vehicle as claimed in claim 1, wherein the transmission includes first and second gears, and the control device is rendered in such a manner that on displacement of the shift lever into the shift paths associated with the first and second gears, starting of the driving engine is initiated.
