The follower is moveable between an out-of-Park position and a Park position and the armature is moveable between an unlocked position and a locked position.

Abstract: The present invention describes a device for locking a lever of a motor vehicle. The device permits an operator to quickly lock the lever in an engaged position and unlock the lever from the engaged position. The device may be used even when the manual dexterity of the operator is limited by protective equipment. The device includes a pin and spring. The pin passes through aligned holes in the flange and lever. Releasing the lever exerts a lateral force on the pin, thereby preventing the pin from lifting from the lever hole and locking the lever in the engaged position. The spring lifts the pin from the locked position when the lateral force is reduced. The device may be used on a brake or clutch lever of a motorcycle, thereby permitting the operator to have at least one free hand at a stop.

Abstract: The first gear/reverse gate switch of the present invention includes a detent switch including a contact pin and a contact switch. When a manual transmission is shifted to a gear not in the first gear/reverse gate, the contact pin of the detent switch engages a recessed portion on a detent mechanism such that the contact pin does not engage the contact switch.

When the manual transmission is shifted to a gear in the first gear/reverse gate, the interlock moves the detent, pushing the contact pin into engagement with the contact switch. This indicates that the transmission is in a gear in the first gear/reverse gate. The spring forces the detent into a “relaxed position” when not in the first gear or the reverse gate, breaking switch contact.
