Child restraint with recline
A child restraint with recline includes a base, a seat slidably disposed thereon, and a locking mechanism. The locking mechanism is disposed in the base and the seat correspondingly and includes a pawl, two actuators, and a plurality of holes. The pawl is biased to protrude out to be selectively inserted into one of the plurality of holes. Each actuator includes a manipulation portion and a connecting portion kinematically connecting the manipulation portion and the pawl. The manipulation portions are exposed at the front side and rear sides of the child restraint respectively. The manipulation portion of each actuator is operable to independently drive the pawl through the connecting portion to disengage from the hole which the pawl is engaged with. The recline angle of the seat relative to the base can be adjusted by manipulating the manipulation portions from the front side or rear side of the child restraint.
1. A child restraint with recline, having a front side and a rear side opposite to the front side and comprising:
a base;
a seat, slidably disposed on the base along a curved surface and orientated toward the front side; and
a locking mechanism, comprising a pawl, a front actuator, a rear actuator, and a plurality of holes, the plurality of holes being disposed on one of the seat or the base, the pawl, the front actuator, and the rear actuator being disposed on the other of the seat or the base, the front actuator comprising a front manipulation portion and a front connecting portion, the front connecting portion kinematically connecting the front manipulation portion and the pawl, the rear actuator comprising a rear manipulation portion and a rear connecting portion, the rear connecting portion kinematically connecting the rear manipulation portion and the pawl, the front manipulation portion and the rear manipulation portion being disposed at the front side and the rear side respectively, the pawl being biased to protrude out and to be selectively inserted into one of the plurality of holes, the front manipulation portion and the rear manipulation portion being operable to independently drive the pawl through the front connecting portion and the rear connecting portion respectively to disengage from the hole which the pawl is engaged with.
2. The child restraint with recline of claim 1 , wherein the pawl is pivotally connected to the base or the seat, and the locking mechanism comprises a bias spring biasing the pawl to protrude out.
3. The child restraint with recline of claim 2 , wherein the plurality of holes are formed on a bottom portion of the seat, the pawl, the front actuator, and the rear actuator are disposed in the base, the pawl comprises a pivotal portion and a locking portion connected to the pivotal portion, the pivotal portion is pivotally connected to the base, and the bias spring biases the pivotal portion to rotate in a rotation direction so that the locking portion protrudes out of the base and is selectively inserted into one of the plurality of holes.
4. The child restraint with recline of claim 3 , wherein the front connecting portion comprises a front wedge and a front flexible member, the front flexible member connects the front wedge and the front manipulation portion, the front wedge has a front ramped surface abutting against the pivotal portion, and the front manipulation portion is operable to draw the front wedge through the front flexible member so that the front wedge drives the pivotal portion through the front ramped surface to rotate in a reverse rotation direction opposite to the rotation direction.
5. The child restraint with recline of claim 4 , wherein the rear connecting portion comprises a rear wedge and a rear flexible member, the rear flexible member connects the rear wedge and the rear manipulation, the rear wedge has a rear ramped surface abutting against the pivotal portion, and the rear manipulation portion is operable to draw the rear wedge through the rear flexible member so that the rear wedge drives the pivotal portion through the rear ramped surface to rotate in the reverse rotation direction.
6. The child restraint with recline of claim 4 , wherein the pivotal portion has a ramped surface abutting against the front ramped surface of the front wedge.
7. The child restraint with recline of claim 4 , wherein the front manipulation portion is operable to draw the front wedge through the front flexible member to move in a movement direction perpendicular to a plane where the pivotal portion rotates.
8. The child restraint with recline of claim 4 , wherein the front actuator comprises a front restoring spring, connected to the front manipulation portion and the base, when the front manipulation portion is located at a first position, the locking portion is inserted into one of the plurality of holes, and when the front manipulation portion is located at a second position, the locking portion is disengaged from the hole which the locking portion is engaged with, and the front restoring spring is elastically deformed to urge the front manipulation portion back to the first position.
