Description

sun visor

technical field

This invention relates to sun awnings. More specifically, it relates to providing a sunshade that can be folded or unfolded as the child grows, thereby effectively blocking ultraviolet rays that have harmful effects on the child's skin and preventing glare when the child is taken out in a car seat, In addition, a ventilation film is installed to allow smooth ventilation and maintain a cool feeling. This is a child's car seat sun visor.

Background technique

In particular, children's skin is thin and sensitive to external stimuli, and unlike adults, a sebum-based skin protection system is not formed, so it is very harmful when exposed to ultraviolet rays for a long time, and more attention is required to skin management.

Usually, the sunshield is made of cloth and is set only above the child's head, and many follow the direction of the sun, and the child's skin is directly exposed to harmful sun rays, and it is difficult to prevent the child's glare or internal temperature rise wait. The part of the child's car seat that is completely covered by the sun visor is blocked from the flow of air, and the temperature rises greatly due to the radiated heat of the cloth based on the sun visor, so it is difficult for the child sitting in the car seat to withstand the rising temperature, And since the front view is blocked, the child will be bored.

Moreover, in summer, when the car is exposed to direct light for a long time, the temperature inside the sealed vehicle will rise to a dangerous level for children. Even if the interior is ventilated or the air conditioner is turned on to cool down, the car that receives the most direct light The ultraviolet rays received by the front glass of the car will directly or indirectly affect the children sitting in the passenger seat.

Conventionally, in terms of car seats, as shown in FIG. 1 , a sun visor for children is used by attaching a sun visor 2 to the car seat 1 for children in order to prevent the sunlight entering through the front glass of the car from directly irradiating the car seat 1 for children.

The angle of incidence of sunlight changes with seasons or time. If the angle of incidence of sunlight is different, the sunlight will be irradiated obliquely. Therefore, there is a problem that such sunlight cannot be properly blocked at the angle of the sunshade 2 installed for the first time. Therefore, It is necessary to be able to freely adjust the inclination of the sunshade 2 to effectively shield the sunshade from the scorching sun.

In addition, the sunshade 2 installed on the commonly used child car seat cannot be folded and stored when not in use, so it needs to be separated, and since it is only commonly used for newborns, it can only be used for a short period of time for rapidly growing children. It is not efficient, and because it will not be needed soon, it will also become a large burden on the user in terms of cost.

Also, since the sunshade cannot be adjusted and is short in length, there are limitations in the angle at which the sunshade can be blocked.

So the reality is that a solution is needed for this.
