6 Claims. (Cl. 297-285)
A chair assembly 18 is provided for suspension be
The present invention relates to an article of furniture
and more speci?cally to a baby sit-up device which is
ideally and uniquely suited for supporting a child from
three months to ?fteen months of age in a sit-up position,
and which is portable so that it can be easily moved
from one location to another.
While baby sit-up devices as such are not broadly new,
the devices presently available do not provide means for 15
readily adjusting the angle of support for the child, nor
is the support element supported so as to adjust to the
weight and movement of the child. In effect, the devices
presently available provide nothing more than a chair
support ?xed at a pre-determined angle for support of
a child without provision for adjusting the angle to the
comfort of the child or for absorbing the weight and
movement of the child. The baby sit-up of the present
device provides a chair assembly which can be sup
ported in any desirable angled relationship, and such chair
assembly is further resiliently suspended so as to auto
matically adjust to the weight and any movement of the
child. The present device is further portable so that it
can be readily moved from one location to the other.
It is therefore a primary object of the present invention
to generally improve the construction of furniture of this
type.
tween the side panels 11 and 12 and, as will be more
fully appreciated hereinafter, supports ‘a child in a sit
ting up position, which position has been found to be
excellent for holding the child during feeding. This chair
assembly comprises a back rest 19 which is preferably
formed of suitable sheet material, such as plywood, and
a seat rest 20 which is also preferably formed of ply
wood and, as will be readily understood, acts as both a
seat rest and a foot rest for a relatively small child occu
pying the chair. The seat rest 20 is hingedly connected
with the back rest 19 at a point slightly remote from.
the lower end 21 of the back restv by a suitable piano
hinge 22 so that any desired angle of inclination of' the
seat rest 20 with reference to the back rest 19 can easily
be achieved.
The respective side panels 11 and 12, as previously
suggested, are formed of rigid material, preferably peg
board, which board has a plurality of holes or openings
23 formed therein. A support rod 24 and a support rod
25 are extended through aligned openings formed in the
respective side panels and so located as to support the
back rest 19 adjacent its upper end 26, and the seat rest
20 adjacent its upper end 27. It will be appreciated that
the angle of inclination of the seat rest 20 with reference
to the back rest 19 is determined principally by the loca
tion of respective rods 24 and 25, and since the side panels

In reviewing the details of the above-described con
struction, it will be appreciated that the chair assembly
not only is adjustable for supporting the child in any desir
able angled sit-up position, but is resiliently suspended
between the respective side panels for automatic adjust
ment in accordance with the weight or movement of the
child. It is naturally contemplated ‘that a mat of one
form or another 42 will be carried on the chair assembly

spaced from said hinge point thereof so as to freely
suspend said chair.
4. A sit-up device as de?ned in claim 3, including stop
means supported on said side panels and selectively posi
tionable into a position for engagement by said chair as
sembly for limiting movement of said chair assembly
against the bias of said spring means.
5. In a baby sit-up device comprising:
a frame having its side panels disposed in upstanding,
spaced apart, and substantially parallel relationship;
for affording still greater comfort to the infant. It is, of 15
course, obvious that the side panels formed of pegboard
permit ventilation within the device, greatly adding to the
comfort of the infant, and also the adjustable and sup
porting features of the device are of great posture and
20
health bene?t to the infant.
What is claimed is:
1. A baby sit-up device comprising a frame having
side panels disposed in upstanding, spaced, substantially
parallel relationship, a chair assembly comprising a back

said seat rest, and spring means ?xed at one of its ends
to said side panels and connected at its opposite end to
said chair assembly so as to resiliently suspend said chair 30
assembly in its pre-determined angled relationship.
a chair assembly for support by said frame between said
side panels and comprising a back rest, a seat rest
hingedly ?xed on said back rest so as to be in angu

of said chair assembly whereby said chair assembly
is automatically adjustable relative to the weight of
the occupant of the chair assembly.
6. A baby sit-up device comprising:
a frame having side panels including a pair of perfo
rated panels disposed in upstanding, spaced apart,
substantially parallel relationship with said perfo
