  • Patent number: 6966237
    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. This indicates that the transmission is not in a gear in the first gear/reverse gate. 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.

  • Patent number: 6725738
    Abstract: A gear shift apparatus for a manual transmission utilizes an actuator to prevent a miss shift manipulation from a forward gear stage to a reverse gear stage. The gear shift apparatus permits the driver to forcedly release a mis-shift preventing state with a smaller force. In the gear shift apparatus for a manual transmission, a select cam is responsive to a selecting manipulation to pivotally move to forward positions corresponding to forward select positions and a reverse position corresponding to a reverse select position. A restraint cam is driven to a prohibiting position by a plunger when a solenoid is energized to prohibit the select cam from pivotally moving to the reverse position. In this prohibiting state, as the select cam is pivotally moved toward a forward position in response to a manipulation for selecting a forward select position, a release protrusion of the select cam presses the restraint cam to pivotally move the same from the prohibiting state to a permitting position.
