  • Patent number: 11105127
    Abstract: A vehicle hood latching mechanism, having a latch member pivotally connected to a housing defining a striker channel. The latch member includes a primary catch portion between the intersection of a first lever arm and a second lever arm, a secondary catch portion on the first lever arm facing the primary catch portion, and a latch cam surface on the second lever arm proximal to the primary catch portion. The latch cam surface is configured such that a force applied onto the latch cam surface causes the latch member to pivot to a first position. A cancel lever is pivotally mounted to an end of the second lever arm of the latch member and includes an exterior cam surface configured such that a force applied onto the exterior cam surface induces a moment M onto the second lever arm causing the latch member to rotate into the first position.

  • Patent number: 10822846
    Abstract: A latching mechanism configured to fasten a hood panel to a vehicle body for covering a vehicle under-hood compartment includes a fork bolt positionable between a first position and at least one second position having a channel configured to capture the striker. A device releasably engages the fork bolt to adjust the fork bolt from the first position to the second position. A latch is positionable between at least the second position and a third position and includes a body including a primary catch portion and a secondary catch portion configured to releasably engage the striker in the second position. An actuator cooperates with the device and includes a projection configured to engage a portion of the latch body to adjust the latch from the second position to the third position. The secondary catch portion releases the striker in the third position.

The latch member includes a primary catch portion between the intersection of a first lever arm and a second lever arm, a secondary catch portion on the first lever arm facing the primary catch portion, and a latch cam surface on the second lever arm proximal to the primary catch portion. The latch cam surface is configured such that a force applied onto the latch cam surface causes the latch member to pivot to a first position. A cancel lever is pivotally mounted to an end of the second lever arm of the latch member and includes an exterior cam surface configured such that a force applied onto the exterior cam surface induces a moment M onto the second lever arm causing the latch member to rotate into the first position.

  • Publication number: 20190218833
    Abstract: A latching mechanism to fasten a hood panel to a vehicle body includes a housing, a fork bolt releasably securing a striker and a component releasably engaging the fork bolt to adjust the fork bolt. A latch includes a body, a primary catch portion, a secondary catch portion and a pin extending from the body. A memory lever includes a body having a recess to receive the latch pin. A cancel lever includes a body having a first end adjustably connected to the memory lever and a second end extending proximate the second catch portion. The cancel lever cooperates with the secondary catch portion to engage the striker in the first unlatched position. The latch pin is received by the memory lever recess to releasably secure the latch in the second unlatched position and allow the striker to move from the latching mechanism to unfasten the hood panel.
