  • Publication number: 20070182220
    Abstract: 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.
