Vehicle seat with built-in retractable child seat

A retractable child seat for main seat assemblies and pivotally mounted thereto. The child seat includes a seat member and a back member pivotally mounted to each other and the main seat assembly includes a pivotally mounted platform cushion where the child seat is supported by a rail assembly that allows to slidably move back and forth. Under a different embodiment, the child seat is built inside the back member of the main seat and the child seat portion is pivotally mounted thereon. Another embodiment houses the child seat inside the seat member of the main seat when not in use and a user can bring it out through supporting members pivotally mounted to structural elements inside the seat member of the main seat.

BACKGROUND OF THE INVENTION 
1. Field of the Invention 
The present invention relates to child seats, and more particularly, to 
such seats that are retractable and built inside seats of vehicles like 
automobiles. 
2. Description of the Related Art 
Several designs for children's seats exist today and they are typically 
fastened to the rear seat of an automobile. None of these designs, 
however, is built inside the vehicle's seat. Most of these designs utilize 
the seat belts provided by the automobile manufacturer to secure the child 
seat to the automobile's main seat. 
SUMMARY OF THE INVENTION 
It is one of the main objects of the present invention to provide a 
retractable child seat that is built inside an automobile back seat and 
that can be readily made operational. 
It is another object of the present invention to provide a child seat that 
is firmly mounted to the seat and that provide effective protection to the 
child user. 
It is yet another object of this invention to provide such a device that is 
inexpensive to manufacture and maintain while retaining its effectiveness. 
Further objects of the invention will be brought out in the following part 
of the specification, wherein detailed description is for the purpose of 
fully disclosing the invention without placing limitations thereon.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
Referring now to FIGS. 1 through 3, where the present invention is 
generally referred to with numeral 10, it can be observed that it 
basically includes a child seat member 20 and a child back member 30 
hingedly mounted thereon through plate 25. Plate 25 has two ends pivotally 
mounted to members 20 and 30. Member 30 is rotated forwardly towards 
member 20 when it is going to be stored and child seat 10 is slid back 
over rail assembly 40 so that it can achieve the position shown in FIG. 3. 
Rail mechanism 40 includes outer sleeve 42 that is, in the first preferred 
embodiment, rigidly mounted on internal surface 52 of rotating platform 
cushion 50 that in turn is pivotally mounted to axle 60. Axle 60 is 
rigidly mounted to a structural member of the main seat assembly 70. A 
locking mechanism 80 is used to adjust firmly the position of seat 10 
along rail assembly 40. Inner tubular member 44 is housed within outer 
sleeve member 42 and the former includes several holes 45 that receive 
spring loaded pin 46 that protrude through openings 47 in sleeve member 
42. Seat belt assembly 90 is conventionally used to secure the child to 
his or her seat 10. Spacers 48 are mounted over threaded holes 49 to allow 
screws 41 through. This way, the underside of seat member 20 is rigidly 
mounted to inner tubular member 44. 
The second embodiment is shown in FIGS. 5; 6 and 7 and includes axle 160 
that pivotally supports child seat member 120. The back member 130 of 
child seat 100 is defined by an inner wall of the back of main seat 170 
inside a back cavity defined therein. Cushion 115, as shown in FIGS. 5 and 
6, is suspended above the child's head by strap 116 that is removably 
mounted to the upper portion of the back of main seat seat 170 through 
pads of synthetic materials which adhere when pressed together, such as 
VELCRO pads 117, or other equivalent means, such as snap buttons or the 
like. The other end of strap 116 is sewn to cushion 115. Again, 
conventional seat belt assembly 190 is provided to secure the child to his 
seat 100. 
The third embodiment is represented in FIGS. 8, 9 and 10 and it is stored, 
when it is not being used, inside the seat portion of main seat 270. It 
includes child's seat member 220 and back member 230 similar to the ones 
shown in connection with the first embodiment. Support mechanism 250 
provides the support for child seat 200 and locks in place as shown in 
FIG. 9 and collapses to the position shown in FIG. 10. Support mechanism 
250 basically includes members 252 and 254 pivotally mounted to seat 
member 220 at 256 and 258, respectively. Member 254 is, in this third 
preferred embodiment, pivotally mounted at the other end to a firm point 
259 inside the seat portion of main seat assembly 270. Locking mechanism 
280 provides for the adjustment of the position of member 252 along rail 
240, as seen in FIG. 11. In the third embodiment the rear of rail 240 
includes a protruberance where a guiding recess 241 is included to receive 
the end of member 252 and in cooperation with spring loaded pin member 246 
is firmly held in place when the latter is inserted through opening 247. 
A cover 272 is hingedly mounted to the front of seat assembly 270 and it is 
sufficiently cushioned to provide a confortable seating area to a user 
while at the same time covers child seat 200. Structural support is 
provided to cover 272 by child seat 200 when housed within a seat cavity 
and provides a supporting structure. 
It is believed the foregoing description conveys the best understanding of 
the objects and advantages of the present invention. Different embodiments 
may be made of the inventive concept of this invention. It is to be 
understood that all matter disclosed herein is to be interpreted merely as 
illustrative, and not in a limiting sense.
