Child car seats, including seats for infants and toddlers, are required by law depending on the age and size of the child. Children are too small to safely use standard restraint systems such as seatbelts without modification. Parents have available to them child car seats in multiple sizes and configurations. These child car seats are positioned on a conventional rear car seat and secured to the conventional rear car seat according to manufacturer and government recommendations. Children sit and are secured in the child car seat.
Typically, for the smallest children the child car seat is secured to the conventional rear car seat in either a forward-facing or rear-facing position with the seatbelt (lap belt or lap/shoulder belt combination) provided in all vehicles. The child is then secured to the child car seat with a restraint system (such as a 5-point harness, an overhead shield, or a t-shield) permanently connected to the child car seat.
For larger children, a forward-facing child car seat called a booster seat is often used. The booster seat is placed on the conventional rear car seat, the child sits in the booster seat, and the lap/shoulder belt of the vehicle is used to secure both the child and the booster seat to the conventional rear car seat.
When the child car seat is installed, the seat is not usable by an adult. Since installing and uninstalling a child car seat is often cumbersome and time consuming, many parents often simply leave the child car seat installed, thus sacrificing some or all of the rear seat of their car. In addition, when the child car seat is not installed, it must be stored somewhere, oftentimes in the trunk or back storage area of the vehicle. So, some or all of the trunk thus becomes unusable for storing common items such as groceries and luggage. Parents must also purchase child car seats of various sizes and configurations to accommodate their growing children.
Many child car seat manufacturers have attempted to make their product easier to manipulate by making them out of lighter materials, and including a handle for carrying the car seat, but this does not eliminate, and only slightly reduces the awkwardness and annoyance of constantly having to swap, install, and uninstall child car seats.
Thus, a need presently exists for an adjustable child car seat that is integrated and is storable, collapsible, and extendable from a conventional rear vehicle seat.
An integrated seat comprises a first seat and an integrated tractable seating arrangement. The tractable seating arrangement is integrated within the first seat. The tractable seating arrangement can be extended from a stored position within the first seat into a usable position outside of the first seat. The first seat comprises a first seat back and a first seat base. The integrated tractable seating arrangement comprises a second seat back and a second seat base. The integrated seat also comprises means for extending said tractable seating arrangement from a stored position to a usable position. When in the usable position, the second seat base and the second seat back are connected. The integrated seat also comprises means for rotating the tractable seating arrangement between a forward-facing position and a rear-facing position. In one embodiment, the tractable seating arrangement may be extended, positioned (such as rotated), or retracted automatically by pressing a button or a switch.
The foregoing paragraph has been provided by way of general introduction and it should not be used to narrow the scope of the following claims. The embodiments will now be described with reference to the attached drawings.
Briefly, with reference to the side views of
The tractable seating arrangement 102 is extended from the first seat 100 as shown in
When the tractable seating arrangement is no longer needed for carrying the child, back cushion 106 is returned and connected to first seat back 104, thereby storing the tractable seating arrangement and freeing up the first seat for use by an adult or older child. Not shown is a safety belt such as a lap or lap/shoulder belt for the first seat. Such safety belts are well understood in the art and are standard to all automobiles.
Examining
The tractable seating arrangement 102 is extended from a stored position (
In one embodiment, sliding pivot 118 includes a sliding channel fixed to first seat back 104, and a slider or pin secured in the sliding channel. The slider is further attached to back cushion 106 such that back cushion 106 is free to rotate about the axis of the slider or pin. In other embodiments, back cushion 106 is hinged to first seat back 104 by using one or more of butterfly hinges, pivot hinges, butt hinges, and the like.
With particular reference to
Examining
Second seat base 114 is secured to back cushion 106 by channel 116 into which a roller pin 120 or a disk or equivalent is locked (
While various embodiments comprise a channel 116 and roller pin 120 to allow tractable seating arrangement 102 to move in a horizontal direction and to rotate, it should be apparent to one skilled in the art that the teachings of the invention may be employed for any arrangement that is capable of moving tractable seating arrangement 102 in a horizontal direction and rotating tractable seating arrangement 102 about the pivot point. Hence, in various embodiments, channel 116 and roller pin 120 can be replaced, without limitation, by a shaft and pin arrangement, slider crank arrangement with a pin centrally connected to the slider, and the like.
In one embodiment, tractable seating arrangement 102 is pivoted about a pin. The pin is connected at a right angle to the shaft. Further, the shaft is slideably connected to back cushion 106. Many other embodiments are possible. In another embodiment, tractable seating arrangement 102 is vertically adjustable, that is, the distance between the second seat base 114 and the base cushion 108 is adjustable by way of a piston, pin, shaft, or guide (not shown) connecting the second seat base to the channel 116.
In another embodiment, the tractable seating arrangement may be released completely from the channel-pin arrangement or equivalent and carried away to be used as a conventional baby carrier. Later, the tractable seating arrangement may be simply locked into the channel. In this embodiment, the tractable seating arrangement comprises a handle for carrying the baby carrier. The handle is connected, for example, to the second seat back. The tractable seating arrangement is released completely from the channel-pin arrangement or equivalent by pressing, for example, a button located on the carrying handle. In another embodiment the button may be part of a remote control as disclosed below. Either way, pressing the button moves or repositions components of the channel-pin arrangement or equivalent so that the tractable seating arrangement is released from the channel or equivalent. Once released, the tractable seating arrangement may be carried as a separate seat from the first seat. The tractable seating arrangement is reconnected to the first seat by placing the tractable seating arrangement in alignment with the channel-pin arrangement or equivalent and pressing, snapping, or latching into place.
The above disclosure shows a tractable seating arrangement integrated into the first seat back, however it should be apparent to those of ordinary skill in the art that the tractable seating arrangement could equivalently be integrated into the first seat base.

Rear back 410 and sliding member 414 with second seat back 418 may be moved, positioned and locked by any number of channels, guides, hinges, anchors, buckles, straps, locks, bearings, and the like.
As already discussed, tractable seating arrangement 102 comprises second seat back 112, and second seat base 114. In order to accommodate children of varying sizes, in one embodiment, the tractable seating arrangement 102 is expandable so that the second seat base 114 and second seat back 112 can be widened, and that second seat back 112 can be lengthened.
Second seat back 112 and second seat base 114 comprise a vertical split indicated by line 502 to form a left portion 504 and a right portion 506. Left portion 504 and right portion 506 are slideably connected using any number of guides, channels, and the like. Left portion 504 and right portion 506 may be separated in the directions indicated by arrows 508 and 510, thereby widening the tractable seating arrangement.
Tractable seating arrangement 102 comprises a central portion 512 which fills the gap formed when left portion 504 and right portion 506 are separated. In one embodiment, center portion 512 comprises an inflatable cavity, such as an inflatable bag which is inflated either manually or automatically to the desired size and firmness. When not expanded, the inflatable bag is stored between left portion 504 and right portion 506 in a cavity (not shown). So, in operation, left portion 504 and right portion 506 are separated by a length desired by a user, exposing the deflated bag. The deflated bag is then inflated to form a safe and comfortable center portion 512. In another embodiment, center portion 512 comprises a padded insert placed into the gap formed between left portion 504 and right portion 506.

The tractable seating arrangement may include slide-on or attachable padding such as head rests, arm rests, foot rests, and the like. The arms or rests of the tractable seating arrangement may be removable, or replaceable with different sized arms. Further, the tractable seating arrangement may comprise various air bags in various positions on and in the tractable seating arrangement which can be inflated to surround, protect, or cradle a child. These can be used as pillows or padding for comfort and safety, and can also be activated in the event of an accident in the same manner as an air bag is deployed in auto accidents.
Also, tractable seating arrangement 102 may be made of any number of materials such as aluminum, steel, other metals, alloys, wood, plastic, polymers, rubber, foam, sponge-like materials, and synthetic materials. Materials that can compress and conform to the occupant of the tractable seating arrangement such as various fabrics and paddings may be used.
The steps of extending or storing the tractable child seat, for example, unlatching, extending, optionally rotating, locking, and the like can be done either manually or automatically. For automatic operation, the present invention includes electric motors such as stepper motors, DC motors, hydraulic pumps, pneumatic pumps, air pumps, actuators such as mechanical, electric, hydraulic, and pneumatic actuators, gears, rack and pinion arrangements, slider crank arrangement, solenoids, hydraulic and pneumatic piston arms, linkage mechanisms, pulley arrangements, electromagnetic latches, switches, magnetic locks, valves, and the like.
In one embodiment, at least one switch or button is provided on a dashboard of the automobile or other vehicle. A user opens or closes tractable seating arrangement 102, rotates tractable seating arrangement 102, moves tractable seating arrangement 102, and so on, by actuating or pressing the switches or buttons. In another embodiment, the switch or button is located near tractable seating arrangement 102, for example on the side of first seat 100, or stored in a pocket in or near tractable seating arrangement 102. In another embodiment, the switches or buttons are part of a wireless remote control, such as an infrared or radio frequency remote control. The switches or buttons may also unlock doors or start the engine of the vehicle so that, for example, when the button is pressed, the door closest to the tractable seating arrangement opens and the tractable seating arrangement is extended to a usable position.
In operation, as discussed, for manual operation, tractable seating arrangement 102 may be moved from the stored position as shown in
In automatic operation, electronic, electrical, and electromechanical components perform the pulling, pushing, and repositioning described above. For example, first seat 100 may include motors, actuators, and switches disposed within first seat 100 such as, but not limited to, first seat base 110 and first seat back 104. The motors, actuators, and latches lock, release, and reposition the movable components.
The motors may include electric motors such as stepper motors, AC motors, and DC motors, and may be powered by a vehicle battery. The motors may also include hydraulic motors powered by a hydraulic pump. The actuators may include mechanical, hydraulic, and pneumatic actuators connected to, for example, gears, rack and pinion arrangements, slider crank arrangement, hydraulic and pneumatic piston arms, linkage mechanisms, pulley arrangements, and the like. These and other components may be fixed to first seat 100, and oriented in different directions to facilitate the repositioning of the components of first seat 100.
This embodiment may comprise still further components such as, for example, a solenoid bolt. The solenoid bolt locks and releases the tractable seating arrangement in channel 116. An electric stepper motor may be used in conjunction with a gear arrangement to rotate tractable seating arrangement 102. The gear arrangement may comprise a worm gear connected to the axle of the electric stepper motor and a worm wheel fixed to second seat base 114, concentric with the pivot hole.
Also, a solenoid bolt can be used as a lock to prevent horizontal or vertical movement of tractable seating arrangement 102. Once the solenoid bolt is released, a hydraulic pump is activated and the hydraulic pump actuates a hydraulic piston. The actuated hydraulic piston pushes or pulls tractable seating arrangement 102 to provide the movement in the horizontal direction (arrow 119 of
Expanding or collapsing the aforementioned air bags, air cavities, or air pockets may also be done automatically by way of air pumps and electromechanical valves.
The motors, pumps, valves, and the like are easily controlled by any conventional and well understood electronic control system. In one embodiment, pressing the buttons or switches to extend, position, or retract the tractable seating arrangement causes a series of electric signals to be output by a control box connected between the buttons and the motors, pumps, and valves. The electric signals activate the components with an intensity, duration, and order necessary for proper extending, positioning, and retracting. Such control systems are well understood by those of ordinary skill in the art.
Finally, while various embodiments of the invention are described herein with first seat 100 being a vehicle seat, it should now evident to those skilled in the art that first seat 100 may comprise any number of seats, such as, without limitation, a bench type seat, a wheel chair, a relaxing chair, an office chair, a lounge chair, a couch, and the like. If the vehicle seat is a bench type seat, as found in most automobiles, the bench type seat may include more than one tractable seating arrangement and each tractable seating arrangement may be used independently of the other. For example, a first tractable seating arrangement may be used in forward-facing position and a second tractable seating arrangement may be used in a rear-facing position. Or the first tractable seating arrangement may be used, while the second is in a stored position.
