Detailed Description

The invention is further described with reference to the accompanying drawings and specific embodiments:

the child safety seat shown in fig. 1 to 5 comprises a seat 1, a backrest 2 arranged at the rear part of the seat 1 and a head rest 3 arranged on the backrest 2 in a sliding manner along the length direction of the backrest 2, wherein the head rest 3 has a lowest first position and a highest second position on the backrest 2, the first position is used for a small-age child, the second position is used for a large-age child, and the second position is located above the first position, and the head rest 3 can slide between the first position and the second position.

The child safety seat further comprises a supporting piece 4 arranged on the backrest 2 in a sliding mode along the length direction of the backrest 2 and a limiting mechanism used for limiting the sliding range of the supporting piece 4, when the head rest 3 is located at the first position, the head rest 3 is separated from the supporting piece 4, and the upper end of the supporting piece 4 is located below the top of the backrest 2; when the head rest 3 is at the second position, the supporting member 4 is located behind the head rest 3 and supports the head rest 3, and the upper end of the supporting member 4 extends upward out of the backrest 2.

The head rest 3 can also be selectively provided with a plurality of positions with different heights between the first position and the second position, when the head rest 3 slides to be in contact with the supporting piece 4, the supporting piece 4 can support the head rest 3, namely, the supporting piece 4 can support the head rest 3 at any position in the sliding interval.

Referring to fig. 5, the limiting mechanism includes a first limiting portion 7 and a second limiting portion 8, which are respectively disposed on the backrest 2 along the length direction of the backrest 2 and located above the first limiting portion 7, the support member 4 is limited to slide between the first limiting portion 7 and the second limiting portion 8, specifically, when the support member 4 slides upwards on the backrest 2 to abut against the second limiting portion 8, the second limiting portion 8 prevents the support member 4 from continuing to slide upwards on the backrest 2; when the support member 4 slides down on the backrest 2 to abut against the first stopper 7, the first stopper 7 prevents the support member 4 from further sliding down on the backrest 2.

In this example, the support member 4 slides between the first stopper 7 and the second stopper 8 by sliding of the head rest 3. Specifically, when the head rest 3 slides from the first position to the second position, the head rest 3 slides to abut against the supporting member 4 and drives the supporting member 4 to slide from the first limiting portion 7 to the second limiting portion 8, the supporting member 4 slides to abut against the second limiting portion 8, the supporting member 4 stops sliding, and the head rest 3 slides to the second position; when the head rest 3 slides from the second position to the first position, the head rest 3 drives the supporting piece 4 to slide from the second limiting part 8 to the first limiting part 7, the supporting piece 4 slides to be abutted against the first limiting part 7, the supporting piece 4 stops sliding, and the head rest 3 continues to slide and is separated from the supporting piece 4 until sliding to the first position.

In this example, the surface of the supporting member 4 that supports in cooperation with the head rest 3 is provided with a protrusion 6, the rear surface of the head rest 3 is provided with an accommodating groove for accommodating the protrusion 6, and when the head rest 3 is located at the second position, the protrusion 6 extends into the accommodating groove; when the head rest 3 slides from the second position to the first position, the head rest 3 acts on the protrusion 6 to drive the support member 4 to slide. The rear surface of head rest 3 is the arcwall face, and the front surface that support piece 4 supported with the rear surface cooperation of head rest 3 also is the arcwall face, and bellying 6 sets up on support piece 4's arcwall face.

In this example, a rail 5 is fixedly provided to the backrest 2 along the longitudinal direction thereof, and the stay 4 is slidably coupled to the upper and middle portions of the rail 5. Specifically, a guide groove extending in the up-down direction may be formed above the guide rail 5, and the support member 4 is fitted in the guide groove and slides in the extending direction of the guide groove. The head rest 3 is also slidably connected to the guide rail 5.

The child safety seat further comprises a locking mechanism for locking the head rest 3 between the first and second positions, respectively, the locking mechanism further locking the head rest 3 at a plurality of different height positions between the first and second positions. The lock mechanism may be any conventional lock mechanism as long as the head rest 3 and the backrest 2 are fixed to each other. In this embodiment, for example, the locking mechanism may be designed to include a locking member 10 movably disposed on the head rest 3 and a plurality of locking grooves 9 opened on the guide rail 5 and distributed in the up-down direction, when the locking member 10 is inserted into one of the locking grooves 9, the locking mechanism is locked, and the head rest 3 is fixed relative to the backrest 2; when the locking pieces 10 are disengaged from all the locking grooves 9, the locking mechanism is unlocked and the head rest 3 is free to slide up and down on the backrest 2.

The working principle of the child safety seat of the embodiment is as follows:

referring to fig. 1 and 2, the head rest 3 is in the first position, the locking mechanism is locked, the head rest 3 is disengaged from the support 4, when the head support 3 needs to slide from the first position to the second position, the locking mechanism is unlocked, the head support 3 is pushed to slide upwards, when the head rest 3 slides to abut against the supporting piece 4, the supporting piece 4 is driven to slide upwards, at this time, the head rest 3 can stay at a required height, the supporting piece 4 can support the head rest 3, the head rest 3 can also continue to drive the supporting piece 4 to slide upwards to abut against the second limiting part 8, the supporting piece 4 stops sliding, the head rest 3 stops sliding to be located at the second position, the locking mechanism is locked, referring to fig. 3 and 4, the head rest 3 and the backrest 2 are relatively fixed, at this time, the supporting piece 4 can support the head rest 3, and the lug boss 6 on the supporting piece 4 is positioned in the accommodating groove of the head rest 3, so that the use safety of the children of the large age is better.

When needing to slide head rest 3 to the primary importance, unblock locking mechanical system promotes head rest 3 and slides downwards, and head rest 3 acts on and drives support piece 4 and slide downwards on bellying 6, and support piece 4 slides downwards to with first spacing portion 7 butt, and support piece 4 stops sliding, makes bellying 6 and holding tank break away from the cooperation hard, and head rest 3 continues to slide downwards to lieing in the primary importance, locking mechanical system, and head rest 3 breaks away from with support piece 4, and head rest 3 supplies the young children to use this moment.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
