Description

Child safety seat headrest

Technical Field

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

Background

The use of child safety seats in automobiles can greatly improve the safety of children riding. The child safety seat is detachably mounted on the middle-row seat or the rear-row seat through the universal interface, and after a child sits on the seat, the body of the child is restrained by the safety belt of the safety seat, so that the child is protected when the automobile is emergently accelerated, decelerated or collided accidentally. To provide a stable support for the child, the safety seat comprises a rear skeleton, the front side of which is covered with foam, thereby forming an inwardly concave seating area. In addition, for making children's head protected, the safety seat headrest generally processes has the headrest chamber, forms the support from children's head rear and both sides to play the guard action to children's head when great lateral acceleration appears in the car. The safety seat headrest has the functions of three-dimensional support and cladding, and simultaneously has the function of limiting the head of a child, so that the comfort of the safety seat headrest is particularly important. Especially in long-distance travel, the child is more sensitive to the insufficient comfort of the safety seat headrest due to the mobility of the child and the tenderness of the skin. There is room for further improvement in the comfort of various prior safety seat headrests.

SUMMERY OF THE UTILITY MODEL

In view of the above, the present invention provides a headrest for a child safety seat.

The technical scheme is as follows:

a headrest of a child safety seat comprises a headrest body, the headrest body is provided with a headrest cavity used for accommodating the head of a passenger, and the key is that,

the inner wall of the headrest cavity is provided with a pillow pad which is attached to and covered on the inner wall of the headrest cavity;

the pillow is made of a viscoelastic material.

Compared with the prior art, the utility model has the beneficial effects that: the pillow can not only deform when stressed, but also synchronously absorb the acting force, play a role in buffering, and slowly recover to the original shape after the acting force is removed, thereby improving the comfort of the headrest.

Drawings

FIG. 2 is a cross-sectional view taken along line A-A of FIG. 1;

fig. 3 is a structural diagram of a second viewing angle according to the present invention.

Detailed Description

The present invention will be further described with reference to the following examples and the accompanying drawings.

As shown in fig. 1 to 3, a child safety seat headrest includes a headrest body 1, the headrest body 1 has a headrest cavity 2 for accommodating a head of a passenger, a pillow 3 is provided on an inner wall of the headrest cavity 2, the pillow 3 is attached to the inner wall of the headrest cavity 2, and the pillow 3 is made of a viscoelastic material. The viscoelasticity has both viscous characteristics and elastic characteristics, so that the elastic deformation has hysteresis of elastic deformation, and the elastic deformation can absorb acting force, plays an excellent role in buffering, and can be slowly restored to an original shape after the acting force is removed. The provision of such a pillow 3 is advantageous for improving the comfort of the headrest.

The headrest body 1 is bent in a U shape, and the open inner cavity enclosed by the headrest body 1 forms the headrest cavity 2. The inner wall of the headrest cavity 2 is also U-shaped and comprises a rear supporting surface 1a and two lateral supporting surfaces 1b, the two lateral supporting surfaces 1b are respectively positioned on the left side and the right side of the rear supporting surface 1a, and the connecting part of the two lateral supporting surfaces 1b and the rear supporting surface 1a is in smooth transition. The pillow 3 is arranged along the inner wall of the head pillow cavity 2, the middle part of the pillow 3 is attached to the rear supporting surface 1a, and two end parts of the pillow 3 are respectively attached to the corresponding lateral supporting surfaces 1 b.

In order to adapt to the physiological curve of the head and neck of the child, as shown in fig. 1 and 3, the portion of the headrest body 1 corresponding to the rear support surface 1a extends downward to form a neck guard portion 4.

As can be seen from fig. 1 and 2, in order to stably position the pillow 3, a positioning concave cavity 1c is formed on the inner wall of the headrest cavity 2, the positioning concave cavity 1c is adapted to the shape of the pillow 3, and the pillow 3 is disposed in the positioning concave cavity 1 c. The back surface of the pillow 3 is attached to the bottom surface of the positioning cavity 1c and is bonded to the bottom surface of the positioning cavity 1 c. The front surface of the pillow 3 is level with the inner wall of the headrest cavity 2 or protrudes out of the inner wall of the headrest cavity 2, so that the head of a child directly contacts the pillow 3 when the child sits on the pillow.

The headrest body 1 may be made of polyurethane foam, has certain elasticity and rigidity, and is used for maintaining the stable shape and vibration reduction of the headrest cavity 2. The pillow 3 can be made of memory foam, and the memory foam is also called slow rebound sponge, and can further play a role in buffering and improving comfort. These materials are all materials that are well established in the art.

Finally, it should be noted that the above-mentioned description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar representations without departing from the spirit and scope of the present invention.
