Patent number: 11433767Abstract: A vehicle kill switch assembly includes a switch that is coupled to a vehicle. The switch is positioned beneath a driver's seat of the vehicle and the switch is electrically coupled to the ignition system of the vehicle. The ignition system is turned off when the switch is disengaged. A biasing unit is coupled to the vehicle and the driver's seat is coupled to the biasing unit. The biasing unit biases the driver's seat upwardly in the vehicle and the biasing unit is compressed when the driver sits in the driver's seat. The switch is engaged when the biasing unit is compressed to facilitate the vehicle to be driven. Conversely, the switch is disengaged when the biasing unit biases the driver's seat upwardly to inhibit the vehicle from being driven.Type: GrantFiled: September 18, 2019Date of Patent: September 6, 2022Inventor: George Rodriguez
