Abstract

A child car seat includes a seat body, in which a child sits, and a base for supporting the seat body, such that the seat body is tiltable in a reclining direction. When forward force larger than a predetermined level is applied to a weight from deceleration larger than a predetermined level generated by a frontal collision of a vehicle or the like, the seat body is operable to move in an upright direction. The child car seat has no possibility to damage a latch mechanism while the child car seat is mounted on a car seat.

Claims

1. A child car seat comprising:

a seat body;

a base for supporting the seat body such that the seat body is tiltable in a reclining direction;

a locking device for applying a lock preventing the seat body from tilting; and

a releasing device for releasing the lock applied by the locking device and allowing a rotation of the seat body in an upright direction when forward deceleration larger than a predetermined level is applied to the child car seat while the seat body is disposed so as to face backward and upward, said releasing device comprising a weight moving forward in response to the deceleration so that the lock is released by movement of the weight,

wherein the locking device comprises a locking bar extending in a transverse direction of the seat body, a latch body provided on the base and engaging the locking bar, and a latch claw rotatably attached to a latch arm so that engagement of the latch body and the locking bar through the latch claw is released by rotation of the latch claw in response to the movement of the weight caused by the deceleration.

2. The child car seat according to claim 1, further comprising a reciprocating device for reciprocating the locking bar in a longitudinal direction thereof, wherein the locking bar retracts to move from a position where the locking bar is engaged with the latch body to another position where the engagement of the locking bar and the latch body is released.

3. A child car seat comprising:

a seat body;

a base for supporting the seat body such that the seat body is tiltable in a reclining direction;

a locking device for applying a lock preventing the seat body from tilting; and

a releasing device for releasing the lock applied by the locking device and allowing a rotation of the seat body in an upright direction when forward deceleration larger than a predetermined level is applied to the child car seat while the seat body is disposed so as to face backward and upward, said releasing device comprising a weight moving forward in response to the deceleration so that the lock is released by movement of the weight,

wherein the locking device comprises a locking bar extending in a transverse direction of the seat body and a latch body provided on the base and engaging the locking bar so that engagement of the latch body and the locking bar is released in response to the movement of the weight caused by the deceleration, and a spring for urging the latch body in a direction so as to engage the locking bar.

4. A child car seat comprising:

a seat body;

a base for supporting the seat body such that the seat body is tiltable in a reclining direction;

a locking device for applying a lock preventing the seat body from tilting; and

a releasing device for releasing the lock applied by the locking device and allowing a rotation of the seat body in an upright direction when forward deceleration larger than a predetermined level is applied to the child car seat while the seat body is disposed so as to face backward and upward, said releasing device comprising a weight moving forward in response to the deceleration so that the lock is released by movement of the weight,

wherein the locking device comprises a locking bar extending in a transverse direction of the seat body and a latch body provided on the base and engaging the locking bar so that engagement of the latch body and the locking bar is released in response to the movement of the weight caused by the deceleration, and

wherein said latch body includes a latch arm, and the weight, as the releasing device, attached to one end of the latch arm with a space therebetween to which the locking bar is located in a reclining position of the seat body.

5. The child car seat according to claim 4, wherein said locking device further includes a latch claw rotatably attached to the latch arm, and a spring for urging the latch claw to intercept the space between the weight and the latch arm to hold the locking bar in the space.

6. The child car seat according to claim 5, wherein the weight is arranged so that when the deceleration is applied to the weight, the latch arm is moved upward to release the latch claw to allow the locking bar to move from the space.
