Abstract
A latch system for a vehicle includes a synchronizer and a lock unit. The synchronizer is configured to block and allow release of a number of latches of the vehicle such that some latches are blocked from being released if other latches are already released. The lock unit is configured to block selectively the release of the number of latches.
Claims17
A latch system for a vehicle, the latch system comprising:
- a tailgate that includes a tailgate frame, a first latch coupled with the tailgate frame, a second latch coupled with the tailgate frame, a third latch coupled with the tailgate frame, an upper handle coupled with the tailgate frame and configured to pivot relative to the tailgate frame, and a lower handle coupled with the tailgate frame and configured to pivot relative to the tailgate frame,
- a synchronizer coupled with the tailgate and configured to block and allow release of the first latch, the second latch, and the third latch, the synchronizer having an enabled arrangement in which the synchronizer is configured to i) release the first latch and the third latch in response to a user pivoting the upper handle to allow the tailgate to rotate about a first axis, ii) release the second latch and the third latch in response to the user pivoting the lower handle to allow the tailgate to rotate about a second axis perpendicular to the first axis, and iii) block more than two latches of the first latch, the second latch, and the third latch from being released at a given time, and
- a lock unit coupled with the synchronizer and configured to move selectively the synchronizer between the enabled arrangement and a disabled arrangement in which the synchronizer allows the upper handle and the lower handle to pivot relative to the tailgate frame without the synchronizer releasing any of the first latch, the second latch, and the third latch in response to the user pivoting one of the upper handle and the lower handle,
- wherein the synchronizer includes a mount and a first release assembly that includes a first latch-actuator lever connected with the first latch, a first handle lever coupled with the upper handle and configured to move relative to the mount in response to the user pivoting the upper handle, and a first sensor unit that is movable between an unlocked arrangement in which the first sensor unit transmits force from the first handle lever to the first latch-actuator lever to move the first latch-actuator lever in response to the user pivoting the upper handle to release the first latch and a locked arrangement in which the first sensor unit does not transmit force from the first handle lever to the first latch-actuator lever in response to the user pivoting the upper handle,
- wherein the first sensor unit includes a first pin that extends through a first slot formed in the first latch-actuator lever, a first sensor lever rigidly coupled with the first pin and configured to rotate to move the first pin in the first slot, and a first sensor rod coupled between the first sensor lever and the second latch and configured to rotate the first sensor lever in response to the lower handle being pivoted,
- wherein the lock unit includes an actuator and a first clasp arm, the actuator is coupled with the first clasp arm and configured to rotate the first clasp arm, the first clasp arm is engaged with the first sensor lever included in the first sensor unit and configured to rotate the first sensor lever to cause the first sensor lever to move the first pin in the first slot such that the first sensor unit is in the locked position in response to rotation of the first clasp arm in a first direction by the actuator to allow the upper handle to pivot without releasing either of the first latch and the third latch.

A latch system for a vehicle, the latch system comprising:
- a synchronizer including a mount, a first release assembly coupled with the mount and movable relative to the mount, and a second release assembly coupled with the mount and movable relative to the mount, the first release assembly configured to release a first latch in response to activation of the first release assembly, the second release assembly configured to release a second latch in response to activation of the second release assembly, and the synchronizer configured to block activation of one of the first release assembly and the second release assembly when the other of the first release assembly and the second release assembly is already activated, and
- a lock unit coupled with the synchronizer and engaged with the first release assembly and the second release assembly, the lock unit configured to block selectively activation of any of the first release assembly and the second release assembly,
- wherein the first release assembly includes a first latch-actuator lever configured to be connected with the first latch such that rotation of the first latch-actuator lever relative to the mount releases the first latch, a first sensor unit movable between an unlocked arrangement and a locked arrangement, and a first handle lever i) configured to apply a force to the first latch-actuator lever through the first sensor unit to cause the first latch-actuator lever to rotate and release the first latch in response to the first sensor unit being in the unlocked arrangement and the first release assembly being activated and ii) configured to not apply the force to the first latch-actuator lever through the first sensor unit in response to the first sensor unit being in the locked arrangement and the first release assembly being activated, and the lock unit is configured to move selectively the first sensor unit between the unlocked arrangement and the locked arrangement,
- wherein the first sensor unit includes a first pin, a first sensor lever, and a first sensor rod, the first pin extends into the first slot formed in the latch-actuator lever and is configured to translate in the first slot between a first position in which the first pin is engagable by the first handle lever and a second position in which the first pin is not engagable by the first handle lever, the first sensor lever is pivotably coupled with the mount and coupled with the first pin and configured to move the first pin between the first position and the second position, and the first sensor rod is coupled with the first sensor lever and the second latch and configured to rotate the first sensor lever, and
- wherein the lock unit is movable between a locked configuration and an unlocked configuration and includes a first clasp arm and a second clasp arm, the first clasp arm blocks activation of the first release assembly and the second clasp arm blocks activation of the second release assembly in response to the lock unit being in the locked configuration, and the first clasp arm allows activation of the first release assembly and the second clasp arm allows activation of the second release assembly in response to the lock unit being in the unlocked configuration,
- wherein the lock unit is configured to selectively move the first sensor lever between the locked arrangement and the unlocked arrangement, wherein the first clasp arm is engaged with the first sensor lever included in the first sensor unit and configured to rotate the first sensor lever to cause the first sensor lever to move the first pin in the first slot such that the first sensor unit is in the locked position in response to rotation of the first clasp arm.
