Latest Patents

Quinlan holds a patent for a "Transmission manual shift lever assembly." This invention features a manual shift lever designed for automatic transmissions, which includes a park position and multiple drive positions. The shift lever is equipped with detents for each position and incorporates both a brake/transmission shift interlock (BTSI) and an ignition interlock. These interlocks independently prevent shifting from the park position until specific operating conditions are met, such as manipulating the ignition key or pressing the brake pedal. A bell crank connected to the interlocks provides the necessary inhibiting structure, while a lost motion mechanism reduces the operator input force required on the bell crank.
