Description

A fully reverse child safety seat

Technical Field

The utility model belongs to the technical field of child safety seats, and particularly relates to a fully reverse child safety seat.

Background Art

Generally, car seats and seat belts are designed for adults. When children with different body shapes from adults use ordinary seat belts, they cannot be protected at all. In the event of a car accident, this may even cause fatal waist injuries and crushing injuries to the neck, cheeks, etc. Therefore, children should use child safety seats when riding in cars. Child safety seats are seats that are fastened to car seats and have restraints. They are only for children and can restrain children in the event of a car accident to ensure their safety.

Usually, child safety seats have a variety of installation methods, such as the seat body is installed forwardly on the seat, the seat body is installed reversely on the seat, and the seat body is rotated on the seat. Different child safety seats should be used for children of different age groups. Among them, infants under 1 year old and weighing no more than 16 kg are usually suitable for rear-facing infant seats or reversible infant and toddler safety seats. This is because the weight of the child's head accounts for a large proportion of the total body weight and the cervical spine is relatively fragile. Once a collision occurs, the head is easily impacted. The baby's face should be facing backward to prevent neck strain. However, when the seat body is installed reversely on the seat, that is, the child faces backward when sitting.

After searching, the child safety seat for cars provided by the Chinese invention patent (publication number CN104627037A) includes a seat and a body; the seat is provided with a telescopic fixing rod; the seat is provided with a rotation adjustment mechanism for adjusting its rotation angle; the bottom of the body is provided with an inclination adjustment mechanism for adjusting its tilt angle and an adjustable headrest provided on the body;

The rotation adjustment mechanism includes a rotating disk and a locking buckle installed inside the seat; the rotating disk is provided with a conical guide groove and annular ridges that enable it to rotate along its own axis in the seat; the seat is provided with a conical boss and annular groove corresponding to the conical guide groove and the annular guide ridge; the conical guide groove is slidably matched with the conical boss; four buckle grooves are evenly distributed on the circumference of the rotating disk, so that the car child safety seat can rotate 360 degrees and be fixed in four directions of front, back, left and right.

In the above-mentioned prior art, since the supporting feet are arranged on the seat, when the chair body is reversely installed on the seat, the force support point of the chair body is only on the seat, which makes the supporting effect of the chair body poor and cannot be used by children with heavier weight and taller height.

Therefore, it is necessary to improve the existing technology.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

As shown in Figures 1 to 3, a fully reverse child safety seat of the utility model comprises a seat 1, a seat body 2 and a support leg 42. The seat body 2 is installed on the seat 1 with its back facing the front seat of the car. The fully reverse installation can prevent the child's head from rushing forward, protect the cervical spine, and be more stable. The seat 1 is fixedly installed on the car seat through an ISOFIX connector, and the support leg 42 is installed on the seat body 2. Furthermore, one end of the support leg 42 is movably installed on the back of the seat body 2, and the other end of the support leg 42 extends toward the car floor. The seat 1 is provided with a connecting belt 3 that cooperates with the support leg 42. The connecting belt 3 is fixedly installed in the seat 1, and the connecting belt 3 is arranged in a ring shape. When the child safety seat is installed to the car seat, the bottom of the support leg 42 abuts against the car floor, and the child's gravity acts on the seat body 2. Due to the angle between the support leg 42 and the car floor, the connection point between the support leg 42 and the seat body 2 is subjected to a component force horizontally toward the side away from the seat 1 and a component force perpendicular to the car floor and downward. The support leg 42 itself has The support leg 42 has a supporting effect and can offset the force component perpendicular to the car floor. In addition, since the horizontal force component support foot 42 has a tendency to move toward the side away from the seat 1, the inner wall of the connecting belt 3 is tightly attached to the outer peripheral surface of the support foot 42, so that the connecting belt 3 is in a taut state, and the connecting belt 3 provides a pulling force close to the seat 1 for the support foot 42. Therefore, the above-mentioned pulling force and the horizontal force component toward the side away from the seat 1 offset each other, thereby preventing the support foot 42 from moving away from the seat 1. In addition, a triangle is formed between the back of the chair body 2, the connecting belt 3 and the support foot 42, so that the connection between the chair body 2, the connecting belt 3 and the support foot 42 is more stable, so that the chair body 2 can withstand children of heavier weight, and can also allow the chair body 2 to withstand greater forces. Therefore, the chair body 2 can be more stably installed on the seat 1, and there will be no situation where the chair body 2 falls off the seat 1 after being subjected to a large force. In addition, it can be suitable for children with a height of 40cm-125cm, and has a wider range of applications.

A connecting seat 421 is provided at the end of the supporting foot 42, and a connecting frame 12 is provided in the chair body 2. The connecting frame 12 is fixedly installed on the seat 1. The connecting frame 12 is a bent tube extending from the seat 1 to the back of the chair body 2. The connecting seat 421 has a connecting plate 422 extending toward the side close to the connecting frame 12. The connecting plate 422 is rotatably connected to the connecting frame 12 through a connecting shaft 423. When the connecting belt 3 is sleeved, it is necessary to manually rotate the supporting foot 42 so that the supporting foot 42 rotates around the axis of the connecting shaft 423, so that the connecting belt 3 can bypass the bottom of the supporting foot 42, so that the inner wall of the connecting belt 3 abuts and cooperates with the supporting foot 42.

The outer periphery of the connecting seat 421 and the supporting foot 42 is covered with a shell 41 , and the shell 41 covers the connection between the connecting seat 421 and the connecting shaft 423 , so as to hide the connection and make it more beautiful.

A clamping portion 43 is provided on the supporting foot 42 , and a clamping hole is provided in the clamping portion 43 for the connecting belt 3 to pass through.

The support foot 42 includes at least two support rods 44, two adjacent support rods 44 are mutually sleeved and telescopically matched, a plurality of adjustment holes 45 are arranged side by side on the support rods 44, and a locking mechanism 431 cooperating with the adjustment hole 45 is also arranged between two adjacent support rods 44. When the support foot 42 needs to be telescopically adjusted, it is only necessary to unlock the locking mechanism 431 first, and the overall length of the support foot 42 can be adjusted. After the adjustment is completed, the corresponding support rod 44 is locked by the locking mechanism 431, so that the adjustment of the support foot 42 can be completed. Regarding the specific structure and principle of the locking mechanism 431, reference can be made to a basket support foot disclosed in the Chinese utility model patent (Announcement No. CN207697562U), which will not be described in detail here.

A support seat 46 is provided at the bottom of the support rod 44 , and a support pad 424 is provided at the bottom of the support seat 46 . When the support pad 424 contacts the vehicle floor, the friction between the support pad 424 and the vehicle floor can be increased.
