Vehicle roll-over protection device

Claim 1

An assembly for stopping and preventing a vehicle having an engine compartment and an engine therein from running in the event of vehicle tilt or roll-over, said assembly comprising a. a system essential for engine operation, b. a means for selectively interrupting and completing said essential system to thereby respectively stop said vehicle engine operation and allow said vehicle engine operation, said means including (i) a movable member selectively movable into and out of engagement with means within said essential System for respectively completing and interrupting said system, said member normally biased out of engagement with said means within said essential system, (ii) a main solenoid operatively associated with said member for moving said member into and out of engagement with said essential system means (iii) a module, said module comprising a unitary assembly of a pilot relay operatively associated with said main solenoid, said pilot relay including an armature operatively connected to relay contact, and first and second solenoids acting in opposition on said armature to move said armature into either a first or a second position respectively, said armature remaining latched in the position to which it is moved until acted upon by the other solenoid, a tilt switch operatively associated with said second solenoid for providing energization of said second solenoid when said vehicle is tilted more than a predetermined amount, said tilt switch always connected to a source of electircal power, and a plurality of terminals for facilitating electrical connection between said pilot relay and said tilt switch, and between said pilot relay and tilt switch and of the components of said means for selectively interrupting and completing said essential system, and (iv) a 3-position operating switch having ''''off'''', ''''on'''', and ''''reset'''' positions, said operating switch having a contact thereof connected to a source of electrical power, said switch in the ''''off'''' position thereof supplying no current from said source to said relay contact, said switch in the ''''on'''' position thereof supplying current from said source to said relay contact, and said switch in the ''''reset'''' position thereof supplying current from said source to said first solenoid.
