ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a technique for changing the capacity of a space for supporting a juvenile whose body is in the process of growth, and more particularly, it relates to a technique for enabling a bed state optimum for a baby based on medical criteria in a neonatal period, infancy or childhood.
2. Description of the Prior Art
The most important factors of a child-care instrument are excellent safeness and comfortability for a juvenile or child. Among child-care instruments, particularly a child safety car seat employed in a car must be comfortable and assure a high safety in supporting a child in a proper state responsive to the growth of the child.
A neonate grows into an infant, a child and a school child, and its habitus or growth changes in this process. Therefore, the juvenile safety car seat must change the space for supporting the juvenile in response to the change of its habitus for regularly providing an optimum space responsive to the growth of the child. Further, it is extremely important to protect the brain, the neck and respiration of the juvenile, particularly a neonate or an infant whose brain is in a developmental stage.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a juvenile safety car seat capable of providing optimum comfortability and safeness for a child with due regard to the growth stage of the child's body.
Another object of the present invention is to provide a child safety car seat improved for easy handling.
Still another object of the present invention is to provide a safety car seat improved in safety on the basis of an improved attachability to a seat of a car.
A further object of the present invention is to provide a protector capable of providing optimum comfortability and safeness for a child with due regard to the growth stage of the child's body, particularly a protector enabling protection with a multilayer structure for a child whose brain is in a developmental stage.
A further object of the present invention relates to a child-care instrument and a bed for a neonate enabling a bed state optimum for a baby based on medical criteria in a neonatal period, infancy or childhood.
The child safety seat according to the present invention provides a child safety seat adapted to be secured to a car seat by a seat belt provided on said car seat, said child safety seat comprising a seat body including a backrest for supporting a child's back, a headrest movably supported by said seat body, said headrest including a head guard wall rising from a plane of said headrest for protecting the top of the head of a child in said safety seat, and headrest moving means operatively connected to said headrest for controlling a position of said headrest including said head guard wall relative to said backrest.
Thus, it is possible to protect the juvenile with a capacity responsive to its growth. Consequently, the child safety car seat has been improved for comfort and safety of the entire child.
In the aforementioned aspect, the capacity-variable device preferably has a head space control device for changing the capacity of a head space that is part of the support space, in response to growth of the head of the child.
Thus, it is possible to protect the head of the child with a capacity responsive to growth of the child. Consequently, the child safety car seat can be improved in comfortability and safeness for the head of the child. The term “juvenile” is used herein as a synonym for “child”.
In order to implement the aforementioned aspect in a more preferable state, the following structures are employed:
More preferably, the aforementioned head space control device includes a head guard for protecting the head of a juvenile and a head guard vertical position control device for controlling the vertical position of the head guard with respect to the head position of the juvenile.
More preferably, the aforementioned head space control device includes a head guard provided substantially above a backrest portion of the aforementioned juvenile safety car seat and a head guard attachment angle control device for controlling the angle of attachment of the head guard with respect to the aforementioned backrest portion, in order to protect the head of the juvenile.
More preferably, the aforementioned head space control device includes a pair of side guards for protecting the lateral surfaces of the head of the juvenile and a side guard vertical position control device for controlling the vertical positions of the aforementioned pair of side guards with respect to the head position of the juvenile.
More preferably, the aforementioned head space control device includes a pair of side guards for protecting the lateral surfaces of the head of the juvenile and a side guard space control device changing the space between the aforementioned pair of side guards.
More preferably, the aforementioned head space control device includes a pair of side guards for protecting the lateral surfaces of the head of the juvenile and a side guard attaching and/or detaching device rendering the aforementioned pair of side guards attachable to and/or detachable from the aforementioned juvenile safety car seat.
More preferably, the aforementioned head space control device includes a head guard and a pair of side guards for protecting the head of the juvenile, a coupling member for coupling the aforementioned head guard and the aforementioned pair of side guards with each other, and a coupling member vertical position control device for controlling the vertical position of the aforementioned coupling member with respect to the head position of the juvenile.
More preferably, the aforementioned head space control device includes a head protector arranged in a clearance defined between the aforementioned head space forming part of the aforementioned support space and the head of the juvenile for forming a head receiving space.
In the aforementioned aspect, the aforementioned capacity-variable device has a shoulder space control device changing the capacity of a shoulder region of the aforementioned support space in response to growth of the shoulders of the juvenile.
Thus, it is possible to protect the shoulders of the juvenile with a capacity responsive to growth of the juvenile. Consequently, the juvenile safety car seat can be improved in comfortability and safeness for the shoulders of the juvenile.
In order to implement the aforementioned aspect in a more preferable state, the following structures are employed:
More preferably, the aforementioned shoulder space control device includes a safety belt having a shoulder belt located on the shoulder of the juvenile and a shoulder belt vertical position control device for controlling the vertical position of the aforementioned shoulder belt with respect to the shoulder position of the juvenile.
More preferably, the aforementioned shoulder space control device includes a safety belt having a shoulder belt located on the shoulder of the juvenile and a shoulder belt width position control device for controlling the position of the shoulder belt in the width direction with respect to the shoulder position of the juvenile.
More preferably, the aforementioned shoulder space control device includes a safety belt having a shoulder belt located on the shoulder of the juvenile and a shoulder belt inclination control device for controlling inclination of the aforementioned shoulder belt with respect to the shoulder position of the juvenile.
More preferably, the aforementioned shoulder space control device includes a shoulder protector arranged in a clearance defined between the aforementioned shoulder region of the aforementioned support space and the shoulder of the juvenile for forming a shoulder receiving space.
In the aforementioned aspect, the aforementioned capacity-variable device preferably has an abdominal space control device changing the capacity of an abdominal region of the aforementioned support space in response to growth of the abdomin
