CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority to and is a continuation-in-part of U.S. patent application Ser. No. 11/062,646, filed Feb. 22, 2005, entitled Folding Chair Cot for Use with Emergency Vehicles, and naming Nathan R. Walkingshaw as the inventor. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a cot, and in particular to a collapsible emergency vehicle chair cot including a support system and a movement system. [0004] 2. Background [0005] Cots are used to transport incapacitated or injured individuals from one location to another. For example, EMTs typically transport emergency medical patients from one location into their ambulances using cots. Early cots merely consisted of cloth stretched between two poles. A patient was positioned on the cloth and two emergency workers carried either end of the poles, thereby supporting the patient. The primary problem with this design is that it requires two emergency workers to use both of their hands to transport their patient. This is problematic because emergency workers typically carry equipment and may need to perform tasks on the patients while being transported. Later, wheels were added to rigid cots to make gurneys which are easier for emergency workers to move patients from a particular location into an emergency vehicle. These added wheels allowed patients to easily be wheeled across flat surfaces to an emergency vehicle. The added wheels are also configured to collapse such that the cot could be properly fitted into an emergency vehicle and serve as a bed during transportation to a hospital. Additional wheels were eventually added to the loading end of cots in order to minimize friction and facilitate wheeling the cot into an emergency vehicle. [0006] While these wheeled gurney embodiments provide significant advantages over the traditional cloth-type cots, there are still significant problems. For example, if the patient must be transported over uneven surfaces such as stairs, curbs, or inclines, the conventional wheeled gurney will still require at least two emergency workers to properly transport the patient. In addition, on steep and irregular inclines, it is very difficult to support and stabilize the uphill side of the wheeled cot because it will be disposed very close to the ground. Further, certain uneven surfaces may cause the cot to bounce or shift resulting in additional pain and possibly injury to the patient. Therefore, for at least these reasons there is a need in the industry for an improved cot. BRIEF SUMMARY OF THE INVENTION [0007] The present invention relates to a collapsible emergency vehicle chair cot that includes a support system and a movement system. The support system is a retractable system disposed on the bottom of the cot to support the chair cot during transportation. For example, one embodiment of a support system includes a track that extends from the bottom for the chair cot. The track supports the chair cot thereby minimizing the need for an emergency worker to manually support the chair cot during transportation. The movement system is coupled to the support system and utilizes rotational movement to assist in moving the chair cot over a surface. For example, one embodiment of a movement system includes coupling a motor system and a brake system to the support system to provide motorized movement. The support system and movement system are configured to be collapsible to facilitate using the chair cot with an emergency vehicle. The chair cot further includes at least two platforms for supporting a patient in a seated position. [0008] These and other features and advantages of the present invention will be set forth or will become more fully apparent in the description that follows and in the appended claims. The features and advantages may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims. Furthermore, the features and advantages of the invention may be learned by the practice of the invention or will be obvious from the description, as set forth hereinafter.
