Carry handle release mechanism for a child seat
View Patent ↗A child safety seat includes a seat shell having a child seating area configured to hold an infant or small child and a mounting base for securing the seat shell into a vehicle. The seat shell includes handle mounts located on opposite lateral sides of the seating area configured to attach opposing ends a movable carry handle in a manner enabling pivoting movement thereof. The carry handle includes a pair of lock mechanisms, one disposed at each handle end that enables the handle to be fixed into a selected pivotal position. Each lock mechanism includes a release actuator enabling the lock mechanism to be unlocked so that the carry handle may be repositioned. The release actuators are interconnected in a manner such that releasing movement of one will be transferred to the other, enabling simultaneous release of both lock mechanisms by operation of either release actuator.
1. A child safety seat having a movable handle comprising:
a seat shell having an infant seating area and first and second handle mounts on opposing sides of the infant seating area;
a handle pivotally coupled to the seat shell such that first and second ends of the handle are mounted to the first and second handle mounts, respectively;
first and second locking mechanisms associated with the first and second ends of the handle, respectively, the locking mechanisms being configured to lock the handle in position relative to the seat shell, the locking mechanisms having first and second actuators, respectively, configured to selectively unlock the respective locking mechanism; and
an interconnecting apparatus connecting the first and second actuators such that moving one actuator to unlock the respective locking mechanism causes the other actuator to be simultaneously moved to release the other locking mechanism and permit the handle to pivot.
2. The safety seat of claim 1 , wherein the first and second actuators are disposed on the first and second locking mechanisms, respectively, and each is movable between generally opposing locked and unlocked positions.
3. The safety seat of claim 2 , wherein the interconnecting apparatus passes through an interior portion of the handle.
4. The safety seat of claim 3 , wherein the interconnecting apparatus comprises a continuous cable loop extending between the first and second actuators and connected thereto, the loop being moved in a first direction by movement of the first actuator from the locked toward the unlocked position, cable loop movement in the first direction causing the second actuator to simultaneously move toward the unlocked position, the cable loop being moved in a second direction opposite of the first direction by movement of the second actuator from the locked toward the unlocked position, cable loop movement in the second direction causing the first actuator to simultaneously move toward the unlocked position.
5. The safety seat of claim 3 , wherein the interconnecting apparatus comprises elongate first and second cables each having a first and a second end, the first ends being connected to the first actuator and the second ends being connected to the second actuator, the first cable being tensioned by movement of the first actuator from the locked toward the unlocked position, the first cable tension causing the second actuator to simultaneously move toward the unlocked position, the second cable being tensioned by movement of the second actuator from the locked toward the unlocked position, the second cable tension causing the first actuator to simultaneously move toward the unlocked position.
6. A child safety seat having a movable handle with a one-handed release mechanism comprising:
a seat shell having an infant seating area and first and second handle mounts on opposing sides of the infant seating area;
a handle pivotally coupled to the seat shell such that first and second ends of the handle are mounted to the first and second handle mounts, respectively; and
first and second locking mechanisms associated with the first and second ends of the handle, respectively, the locking mechanisms being configured to lock the handle in one of a plurality of positions relative to the seat shell, the locking mechanisms having first and second actuators, respectively, configured to selectively unlock the respective locking mechanism, the first and second actuators being interconnected such that unlocking of one of the actuators causes the other actuator to be simultaneously unlocked thereby permitting the handle to pivot.
7. The safety seat of claim 6 , wherein the first and second actuators are disposed on the first and second locking mechanisms, respectively, and each is movable between generally opposing locked and unlocked positions.
8. The safety seat of claim 7 , further comprising an interconnecting apparatus connecting the first and second actuators and configured to move the first actuator and unlock its respective locking mechanism when the second actuator is moved toward the unlocked position to unlock its respective locking mechanism and permit the handle to pivot.
9. The safety seat of claim 8 , wherein the interconnecting apparatus passes through an interior portion of the handle.
10. The safety seat of claim 9 , wherein the interconnecting apparatus comprises elongate first and second cables each having a first and a second end, the first ends being connected to the first actuator and the second ends being connected to the second actuator, the first cable being tensioned by movement of the first actuator from the locked toward the unlocked position, the first cable tension causing the second actuator to simultaneously move toward the unlocked position, the second cable being tensioned by movement of the second actuator from the locked toward the unlocked position, the second cable tension causing the first actuator to simultaneously move toward the unlocked position.
11. The safety seat of claim 9 , wherein the interconnecting apparatus comprises a continuous cable loop extending between the first and second actuators and connected thereto, the loop being moved in a first direction by movement of the first actuator from the locked toward the unlocked position, cable loop movement in the first direction causing the second actuator to simultaneously move toward the unlocked position, the cable loop being moved in a second direction opposite of the first direction by movement of the second actuator from the locked toward the unlocked position, cable loop movement in the second direction causing the first actuator to simultaneously move toward the unlocked position.
