     DETAILED DESCRIPTION 
     Disclosed herein are apparatus, systems, and methods for attaching accessories to wheeled seating devices such as wheel chairs or strollers. In some embodiments, the apparatus and systems include an attachment device which can be configured to connect one or more accessories to a stroller. In one embodiment, the attachment device can provide an accessory attachment point to a stroller. 
     An accessory can include, but is not limited to an additional and/or mountable seat, a cup holder, a basket, a cooling fan, a heating fan, a mister fan, a storage bucket, an electronic device, a cooler, a trash can, a clip, and the like. Mountable seats can include bike stem mountable child seats and/or rear bike mountable child seats. Electronic devices can include, but are not limited to tablets, portable DVD players, electronic ready devices, computers, cellular phones, smart phones, MP3 players, and the like. 
     In one embodiment, an attachment device can provide an attachment point for a mountable seat. In some embodiments, attachment device can be directed to an attachment device for a stroller capable of supporting a seat such as, for example, a stem mountable child seat, or a rear mountable child seat. 
     In some embodiments, the attachment device can be configured, for example, to alter or adjust its size or shape to accommodate different styles and sizes of strollers and/or accessories. Additional embodiments of attachment devices comprise an appendage which an accessory or accessories can be mounted. Additionally, the embodiments of appendage can be directed to attachment of an electronic device. 
     Embodiments of attachment device can be capable of converting a single stroller into a double stroller. Double strollers can be substantially larger than single strollers and are therefore more difficult to maneuver. Additionally, a double stroller may occupy more real-estate within a house or car than a single stroller. The benefit of being able to accommodate both children with a single device outweighs these disadvantages. However, when parents only have one child with them, the benefits of having a double stroller is not realized or even wasted. Parents often keep a single stroller to accommodate times when only one child is transported. Therefore, parents can have both a single and a double stroller occupying more real-estate within their car&#39;s trunk or living area.

     EXAMPLES 
     The following non-limiting examples are provided for illustrative purposes only in order to facilitate a more complete understanding of representative embodiments. These examples should not be construed to limit any of the embodiments described in the present specification including those pertaining to the method of adding an additional seat onto a stroller. 
     Example 1 
     Adding an Additional Seat onto a Single Stroller 
     Parents or guardians have one child. The parents or guardians purchase a single stroller, a stem mountable child seat, and a car seat to transport the child around. Two years later an additional child is born. The parents or guardians are now in need of a double stroller to transport both children around, but do not want the added expense of buying a double stroller. The parents or guardians purchase an attachment device as illustrated in  FIG. 1  to connect the single stroller to a stem mountable seat, converting the single stroller into a double stroller, thus alleviating the need to purchase a double stroller. 
     Example 2 
     Converting a Double Stroller into a Triple Stroller 
     Parents have twin children. The parents purchase a double stroller, a stem mountable child seat, and two car seats to transport the children around. Two years later an additional child is born. The parents are limited on space due to the small apartment they live in. The parents cannot afford to lose their valuable space by adding another stroller to the already large area the double stroller is occupying. The parents purchase the accessory attachment device to connect the double stroller to a stem mountable seat, converting the double stroller into a triple stroller. 
     Example 3 
     Toolless Attachment 
     Parents have one child. The parents purchase a single stroller, a stem mountable child seat, and a car seat to transport the child around. Two years later an additional child is born. The parents do not have any tools to install a device nor can they afford a new double stroller. The parents purchase the accessory attachment device, which does not require any tools to install. The parents are able to slip the accessory attachment device into the head tube/headset assembly of the stroller and then strap it down to the stroller&#39;s frame with the anti-rotation appendages. Thus, alleviating the parents need to buy a double stroller. 
     Example 4 
     Quick Disconnect of Accessory Attachment Device 
     Parents or guardians have one child. The parents or guardians purchase a single stroller, a stem mountable child seat, and a car seat to transport the child around. Two years later an additional child is born. The parent or guardian only wants to take the older child with them to run errands and leaves the younger child with the other parent or guardian. The parents have the attachment device connecting the stroller and the mountable seat. The parents are able to quickly disconnect the stroller from the mountable seat, turning the double stroller back into a single stroller. Thus, allowing the parent to only take the one child in the single stroller without having to take a double stroller. 
     Example 5 
     Adding an Accessory onto the Stroller 
     Parents or guardians have one child. The parents or guardians purchase a single stroller, a stem mountable child seat, and a car seat to transport the child around. Two years later an additional child is born. The parents or guardians like to go on long runs or walks with their child. The child becomes bored of the run or walks, and becomes fussy causing the parents or guardians to cut short their run or walks. The child is usually entertained by the parents tablet, portable DVD player, MP3 player, or portable computer. The parents or guardians purchase the attachment device with the accessory adapter allowing them to attach a tablet, portable DVD player, MP3 player, or portable computer to the stroller. The parents or guardians are now able to walk or run longer, because the child is now entertained during the long walks and runs.
