ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a child safety chair, more particularly to a child safety chair with a belt-adjusting unit for vehicle use.
2. Description of the Related Art
FIGS. 1 and 2
illustrate a conventional child safety chair
100
for a car. The child safety chair
100
includes a seat member
71
, a backrest
73
formed with a pair of elongated slots
711
extending in a longitudinal direction, and a pair of belts
72
extending through the slots
711
, respectively. A belt-adjusting unit includes a pair of parallel retaining blocks
81
that are formed on a rear side of the backrest
73
and that are formed with pairs of retaining grooves
811
which are aligned in the longitudinal direction, and a belt-holding lever
74
that is mounted movably on the backrest
73
and that is adjustable to extend through a selected pair of the retaining grooves
811
in a transverse direction relative to the longitudinal direction. The belts
72
are trained on the belt-holding lever
74
so as to be adjustable together with the belt-holding lever
74
along the longitudinal direction. A pair of handles
75
are connected to the belt-holding lever
74
so as to facilitate operation of the belt-holding lever
74
.
Removal of the belt-holding lever
74
from the selected pair of the retaining grooves
811
when adjusting the level of the belts
72
requires both hands of the user to operate the handles
75
. However, when the child safety chair
100
is installed in a car, it becomes relatively inconvenient to operate the handles
75
with both hands due to the standing position of the user relative to the child safety chair
100
, i.e., the user can only stand at one of left and right sides of the child safety chair
100
, which makes the handles
75
difficult to operate using both hands.
SUMMARY OF THE INVENTION
Therefore, the object of the present invention is to provide a child safety chair that is capable of overcoming the aforesaid drawback of the prior art.
According to the present invention, there is provided a child safety chair that comprises a seat member, a backrest, a belt, and a belt-adjusting unit. The backrest extends upwardly from the seat member, has front and rear sides, and is formed with an elongated slot that extends in a longitudinal direction, that extends through the front and rear sides in a first transverse direction relative to the longitudinal direction, and that is defined by a slot-defining wall which has one side. The belt extends through the slot. The belt-adjusting unit includes a belt-holding member that is mounted movably on the rear side of the backrest, and that has a belt-holding part which is aligned with the slot in the first transverse direction, and which has one side disposed adjacent to and cooperating with the side of the slot-defining wall to define a gap therebetween. The belt-holding part is formed with a plurality of retaining grooves which are indented from the side of the belt-holding part and which are aligned in the longitudinal direction, and a plurality of holding ribs, each of which is disposed between an adjacent pair of the retaining grooves. The belt is adjustable to extend into a selected one of the retaining grooves and to train on an adjacent one of the holding ribs. The belt-holding member is movable in a second transverse direction that is transverse to the longitudinal direction and the first transverse direction between a first position, in which the side of the belt-holding part is spaced apart from the side of the slot-defining wall in the second transverse direction by a first distance that restricts removal of the belt from the selected one of the retaining grooves through the gap, and a second position, in which the side of the belt-holding part is spaced apart from the side of the slot-defining wall in the second transverse direction by a second distance that is larger than the first distance and that permits removal of the belt from the selected one of the retaining grooves through the gap.
