Description
Background of the Invention
1. Field of the Invention
This invention relates to sunshades and impact protection devices for infants. It particularly relates to automobile seats for infants that include sunshades and handles for hand carrying of its occupant while outside of the automobile.
2. Review of the Prior Art
It is widely recognized that infants can not be safely transported within an automobile while held in an adult's arms because the acceleration and deceleration forces generated during emergency stops and during accidents are too great for even a very strong adult and cause the infant to be crushed between the adult's body and the dashboard of the automobile. Car seats providing comfort and security to infants and small children have consequently been made mandatory by state and federal laws.
Even though such seats do protect the child satisfactorily while the automobile is underway, they may offer little protection against strong sunlight, glare, and the like, thereby causing the small occupant much discomfort. Numerous car seat devices that include sunshades of some type have consequently been designed, but they are generally antiquated and ineffective.
In addition, such a car seat is often carried by its handle from an automobile to a building or to an outdoor place for recreation, such as a sandy beach. In such a situation, blowing sand can easily create not only discomfort but also a hazard for the small occupant thereof.

Although these prior art baby carriers provide several helpful features, there are additional problems that remain unsolved. These problems include monitoring of an infant occupant in the rear seat of an automobile by parents without visual strain, rapid and simple fastening of foot and head sunvisors, spacing of these sunvisors from the infant's body, simplified mounting and fastening of sideflaps to the sunvisors in order to protect the infant from wind, blowing sand, and sun, carrying the car seat and infant while it continues to furnish protection from both sunlight and the elements, and reliable operation of its handle at both grip and hub locations.
Summary of the Invention
It is accordingly an object of this invention to provide an infant car seat having sunvisors made of UV protectant materials that are also sufficiently transparent for monitoring of an infant occupant by a parent or other adult without visual strain.
It is another object to provide an infant car seat having a handle that can be single-handedly changed in position.
It is a further object to provide an infant car seat that can be single-handedly carried by an adult, outside of the automobile, while the infant car seat continues to provide protection against sunlight and glare and additionally furnishes protection against blowing sand at a beach and against wind, rain, snow, and other manifestations of inclement weather.
It is an additional object to provide an infant car seat having sunvisors that can be stored unobtrusively and positioned while in use with finger-tip activity by an adult.
It is a still further object to provide an infant car seat having a means for simple and quick removal of the sunvisors when needed.
In accordance with these objects and the principles of this invention, an improved infant car seat is provided that protects its infant occupant from glare and strong sunlight while enabling a parent to monitor the infant without strain, that provides unobtrusive storage of its pair of sunvisors and associated sideflaps, that enables an adult to be able to position the sunvisors and sideflaps with little effort, that has a means for simple and quick removal of the sunvisor and sideflap assembly when needed, that has a means for finger-tip positioning of its handle for single-handed carrying of the car seat and its infant occupant, and that provides protection of the infant from blowing sand and the elements while being carried out of doors by an adult or while resting, for example, on a beach.
The handle may additionally be positioned to facilitate placing an infant within the car seat and for removing the infant therefrom. The handle may also be positioned to provide additional shock protection to the rearward-facing infant during a collision. Finally, the handle may be positioned to elevate the head end of the infant car seat in order to facilitate feeding of the infant and the like.
The infant car seat of this invention generally comprises an integrally molded infant carrier shell, an adjustable handle assembly which is movably attached to the shell, foot and head sunvisors which are readily mounted and easily removable, two pairs of side flaps which are hingedly or selectively attached to the sunvisors, and sunvisor elevation assemblies for both sunvisors that hold the sunvisors above the infant's feet and head. The infant car seat additionally comprises two handle release and positioning assemblies, one being adjacent to the handle grip and the other being a part of each circular handle hub so that the handle may be released and positioned at another of its four positions by means of a finger-tip motion at any of three places. The sunvisors are preferably made of vinyl polymers or a blend of Dacron.sup.R and Lycra.sup.R which are transparent but capable of blocking ultraviolet light. These materials are about one-fourth of a millimeter in thickness and have 50-100 holes per square inch; the holes are 0.75-1.00 mm in diameter.
