Description

Field of the invention

[0001] The present invention relates to an accessory with an actuating element for carrying out locking and releasing operations and to a child seat equipped therewith. Background of the invention

[0002] A child safety seat is designed to secure a child in a vehicle. The child safety seat is installed in the vehicle so that the child can sit on it and is held in place inside the vehicle, ensuring the child's safety while the vehicle is moving. There are two types of safety accessories for the child safety seat on the market: one is a five-point safety belt and the other is a front protector. The child safety seat, which has the front protector attached, can effectively protect the child's cervical spine. After the child is seated in the child safety seat, the front protector is firmly attached to the child safety seat. Since the front protector does not completely secure the child to the child safety seat, the child may bend their body in the event of a sudden impact or emergency braking, and the front protector can provide a buffer for the child, thus reducing the impact on the child's cervical spine.The front protector is typically removable from the child seat. Generally, the front protector can be removed directly from the child seat by operating an actuator on the front protector. However, since the front protector can easily be detached from the child seat by a user incorrectly operating the actuator on the front protector, this can pose a significant risk to a child's safety in a vehicle.

The locking member 5 is fixed to the connecting frame 12. The buffer portion 11 may provide a buffer to a child sitting on the seat body 201. Further, the connecting frame 12 may be slidably arranged on one side of the buffer portion 11.By sliding the connecting frame 12 on the buffer portion 11, a distance between the buffer portion 11 and the main body 201 can be adjusted accordingly when the engaging portion 2 is engaged with the seat body 201, so that the main body 1 can be suitable for children of different sizes.

[0035] It will be Fig. 1 to 10. The detailed description for the operations of the accessory 100 of the present invention is given below.

[0036] When the accessory 100 engages with the crossbar 201a of the seat body 201, the crossbar 201a compresses the first elastic member 22. At this time, the second elastic member 32 drives the sliding actuator 3 to push the engaging hook 21, allowing the engaging hook 21 to pivot to the locking position to engage with the crossbar 201a. Thus, the accessory 100 can be attached to the seat body 201. When the accessory 100 is detached from the seat body 201, the secondary safety lock 6 can be operated to push the insertion pin 4 via the ramp surface 61 of the secondary safety lock 6, allowing the insertion pin 4 to slide to disengage from the locking member 5, and thus the sliding actuator 3 can be operated. At this time, the secondary safety lock 6 compresses the fourth elastic element 62.Subsequently, the operating member 3 can be operated to slide and compress the second elastic member 32 to press the engagement hook 21, so that the engagement hook 21 can rotate to the release position to be released from the crossbar 201a. In this way, the accessory 100 can be released from the seat body 201.
