AI Technical Summary
Existing heat shielding solutions for strollers and bicycle seats fail to effectively manage temperature rise due to direct sunlight and reflective heat from road surfaces, posing risks of heat stroke for children and discomfort for adults, while also being limited in shape adaptability and durability.
A heat-insulating sheet composed of a high-purity aluminum foil and porous fiber material, integrated with a surface zipper, is installed on the stroller hood and seat cover to reflect radiant heat and maintain temperature control, featuring high reflectance and breathability.
The sheet effectively suppresses temperature rise inside the stroller and bicycle seat, preventing heat stroke and maintaining comfort by reflecting radiant heat, while also providing insulation against external cold in winter.

Abstract
Description
[Technical field]
[0001] This invention relates to a heat shield sheet for preventing heatstroke and protecting children, including infants, from heat in moving vehicles. [Background technology]
[0002] Direct sunlight can cause the hood inside the stroller to get very hot, and the back and bottom can get very hot due to the heat reflected from the asphalt pavement and floor, putting children, including infants, at risk of heatstroke. Although there are sheets that can be installed on the outside of the stroller to combat this, the reflected heat can still affect adults pushing the stroller. Patent Document 1 discloses a heat protection device for a stroller, but there is a problem that the effect of the cooling material is limited in time. Patent Document 2 discloses a method for suppressing the temperature rise of the passenger part of a stroller, but there is also a problem that the effect of the cooling material is limited in time. In addition, these cooling materials and cooling materials are laid on the bottom surface, so the back of the body is cooled, but they cannot deal with direct heat from the sunshade hood, and furthermore, it is difficult to deal with all the various shapes of hood surfaces. Patent Document 3 also simply blocks hot air from the road surface. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Utility Model Registration No. 3062917 [Patent Document 2] JP 2005-247313 A [Patent Document 3] JP 2010-179906 A Summary of the Invention [Problem to be solved by the invention]
[0004] Normally, the inside of a stroller becomes hot due to direct heat, and there is a risk of children, including infants, suffering from heat stroke due to the reflected heat from the asphalt pavement and floor of the road. Conventionally, cooling materials or cooling materials have been laid in the passenger compartment to lower body temperature, but there is a time limit to how long the effect can last. In addition, the shapes of the sunshade hood surface in the passenger compartment vary, making it difficult to respond and insufficient. Also, although there are sheets that can be installed on the outer surface of the sunshade hood, the reflected heat can have a negative effect on the adult pushing the stroller. [Means for solving the problem]
[0005] This invention is a heat shielding sheet for baby stroller and bicycle rear seat covers that combines a sheet coated with aluminum foil and a porous fiber material, which is placed on the inside of the baby stroller and bicycle rear seat cover to provide a heat shielding effect. This heat shielding sheet comes in two sheets, one for the bottom and one for the hood, and is attached to the bottom of the passenger area with hook-and-loop fasteners and to the inside of the sunshade hood with hook-and-loop fasteners, and is attached separately. The surface of the heat shielding sheet is made of porous fiber, so it feels good on the skin and is gentle on infants and young children. Effect of the Invention
[0006] This invention is a heat shielding sheet for preventing heat stroke and heat protection for infants and young children riding in a stroller or on the back seat of a bicycle. Taking advantage of the properties of the heat shielding sheet, which reflects 97% of radiant heat, it reflects radiant heat from the sunshade hood of the stroller and suppresses temperature rise. In addition, the heat shielding sheet installed on the bottom of the stroller prevents reflected heat from the asphalt road surface and suppresses temperature rise. This suppresses the temperature rise of the entire internal space of the stroller / bicycle back seat cover, preventing heat stroke and preventing heat. In winter, the heat shielding sheet suppresses heat transfer to the outside, maintaining the temperature of the internal space of the stroller / bicycle back seat cover, which is also effective in preventing the cold. Furthermore, by providing an air layer inside the porous fiber material, it has an electromagnetic wave reflection function and can suppress the temperature rise of the entire internal space. The heat shielding sheet of this invention is not limited to use in strollers or bicycle back seats, but is expected to be applied to other fields as a heat shielding sheet with low radiation performance, high reflection performance and breathability. [Brief description of the drawings]
[0007] [Figure 1] FIG. 2 is a diagram showing the configuration of the heat shield sheet of the present invention. [Diagram 2] FIG. 2 is a cross-sectional view of the heat shield sheet of the present invention installed in a stroller. [Diagram 3] 2 is a cross-sectional view of the heat shield sheet of the present invention installed on a bicycle rear seat cover. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0008] The present invention is a removable heat shielding sheet that suppresses direct heat from sunlight in the passenger compartment of a stroller, bicycle rear seat cover, etc., and is a removable heat shielding sheet that integrates a metal thin film sheet and a porous fiber sheet. As the metal thin film sheet, a high-purity aluminum foil coated with a coating is preferably used, which has high reflection and low radiation performance against direct heat from sunlight and reflected heat from the road surface. In addition, the surface of the heat shielding sheet is preferably a porous fiber material, and the porous fiber material preferably has an air layer inside in order to exhibit the performance of reflecting electromagnetic waves. EXAMPLES
[0009] The heat shield sheet of the present invention is composed of a sheet coated with high-purity aluminum foil and a porous fiber material, and the porous fiber is integrated with the heat shield sheet so that it has the function of reflecting heat while also having breathability. The heat shield sheet is installed on the inner side of the hood, back and bottom of the stroller using hook-and-loop fasteners. Alternatively, it is installed on the inner side of the bicycle rear seat cover using hook-and-loop fasteners. High-purity aluminum foil is preferable because it has a reflectivity of 97%. The coating is necessary to protect the aluminum foil, and examples of the material include epoxy resin. The porous fiber is necessary to secure space to reflect electromagnetic waves, and polystyrene foam is used, for example. The results of the heat shield performance test of the heat shield sheet are shown in Table 1. The installation of the heat shield sheet suppresses the temperature rise of the passenger area.
