Abstract: A buckle for a belt or harness comprising a ring member defining a hollow interior space, a slidable bar, and releasable securable lock.  The ring member has a first and a second side section,  and a  first and a  second end section,  which are connected to one another.  The slidable bar is mounted between the side sections and is movable between a position immediately adjacent the  first end  section and a position  immediately adjacent the second end section.  The first end section of the buckle is securable to one portion of a web of the belt or harness.  A free end portion of a web of the belt or harness is arranged to extend through the ring's interior space between the first end section and the slidable bar, around the bar, and through the space between the bar and the second end section, from which it exits beyond the second end section of the buckle. Pulling on the free end of the web causes the slidable bar with the web section therearound to slide into close proximity with the second end section to fictionally hold the web in place.  The lock is a spring biased member arranged to be normally biased in an extended orientation over the slidable bar to tightly engage it and the web portion wrapped therearound and thereby prevent the accidental release thereof.  The lock is manually actuable to release the spring biased member, the slidable bar and the web section when desired.

Abstract: A secondary ignition switch system that connects to a conventional ignition switch system of a vehicle to provide a security function. The secondary ignition system includes a dashboard mounted double-pole-double-throw (DPDT) switch and a key operated secondary ignition switch. The DPDT switch controls the operation of the primary and secondary ignition switches. To start the engine the DPDT is set to a position to power the secondary ignition switch, such that the engine can be started by turning a secondary key. However, based on the interconnection of the ignition switches the steering column of the vehicle remains locked. Only until the operator uses the primary key to unlock the steering assembly can the car be driven. This system enables the engine of a vehicle to run including powering the accessory circuit (for heating/cooling and power accessories) to warm a vehicle in cold climates with minimized risk since the steering assembly remains locked. In addition, when the secondary key is removed from the secondary ignition switch no current flows to the primary ignition switch rendering the entire system disabled.
