Abstract
A double latch assembly for a motor vehicle having two pivotably mounted closure members is disclosed in which a sequencing lever is used to release first and second pawls used to hold first and second rotatable claws in respective latched positions. A single actuator A1 is used to release both of the pawls but because of the use of a disengageable coupling between the sequencing lever and the second pawl it is ensured that the first pawl is always released before the second pawl. Only a single actuator A1 is required to release both pawls and no sensors are required to control the sequencing of the pawls.
Claims17
A double latch assembly for a motor vehicle, the vehicle having first and second closure members movable between at least an open position and a latched position, each of the closure members having a latch member for cooperation with the double latch assembly to hold the respective closure member in the latched position, the double latch assembly comprising:
- a first rotatable claw for cooperation with the latch member of the first closure member to selectively hold the first closure member in the latched position,
- a first pawl for engagement with a first surface on the first claw so as to hold the first claw in a first position corresponding to the latched position of the first closure member,
- a second rotatable claw for cooperation with the latch member of the second closure member to selectively hold the second closure member in the latched position,
- a second pawl for engagement with a first surface on the second claw so as to hold the second claw in a first position corresponding to the latched position of the second closure member,
- a sequencing lever to selectively release the first and second pawls in a predetermined order, and
- a disengageable coupling is provided between the sequencing lever and the second pawl, the disengageable coupling arranged to mechanically enable the sequencing lever to control releasing of the first and second closure members such that the first closure member is always released to the open position before the second closure member can be released to the open position.
A double latch assembly for a motor vehicle, the motor vehicle having first and second hinged closure members each of the closure members having a latch member for cooperation with a double latch assembly to hold the respective closure member in at least a first latched position and a second latched position, the double latch assembly comprising:
- a first rotatable claw for cooperation with the latch member of the first closure member to selectively hold the first closure member in one of the first latched position and the second latched position,
- a first pawl for engagement with a first surface on the first claw so as to hold the first claw in a first position corresponding to the first latched position of the first closure member,
- a second rotatable claw for cooperation with the latch member of the second closure member to selectively hold the second closure member in one of the first latched position and the second latched position,
- a second pawl for engagement with a first surface on the second claw so as to hold the second claw in a first position corresponding to the first latched position of the second closure member, and
- a power cinch mechanism wherein the power cinch mechanism comprises a single actuator connected to a slideable mounting plate on which the first rotatable claw, the first pawl, the second rotatable claw and the second pawl are rotatably mounted, the slideable mounting plate being moveable by the single actuator between a first position in which the first and second pawls are in their respective first positions and the first and second closure members are in their respective first latched positions and a second position in which the first and second closure members are in their respective second latched positions thereby ensuring the first and second closure members are fully closed when moved to the second latched position.
