Abstract:
1. A combination ambulance cot and chair, comprising: a support frame comprising a pair of upper frame members, a lower frame member, and a pair of side arm members pivotally connected at one end to the upper frame member and to the lower frame member adjacent to the other end, said support frame having a pair of brackets and a pair of linkages, each of said pair of brackets comprising at least one one-piece member, said pair of brackets mounted to said pair of upper frame members; a segmented patient support pivotally mounted to said support frame for movement at least between a chair position and a fully-reclined position, said segmented patient support has a seat segment and a back segment, said seat segment having a side support; and a securing device connected functionally to said support frame and a proximate end of said side support of said seat segment, and configured to releasably secure said combination ambulance cot and chair in at least the fully-reclined position by a remote actuator, wherein said securing device is provided to one of said pair of brackets, wherein said securing device and support frame provide a pin guide-fixed pin arrangement, and wherein said pair of side arm members are pivotally connected to said pair of brackets at a first position on said one-piece member, and wherein a proximate end of said side support of said seat segment is pivotally connected to said pair of brackets at a second position on said one-piece member, and wherein a proximate end of said pair of linkages is pivotally connected to said pair of brackets at a third position on said one-piece member and a distal end of said pair of linkages is pivotally connected to said lower frame member, and wherein said upper frame members are pivotally connected to said pair of brackets at said first position and said second position, and wherein said second position is intermediate said first position and said third position, wherein said back segment is pivotably attached to said support frame, and wherein when said pair of upper frame members are moved from a chair position to a reclined position, said pair of brackets push said pair of linkages lifting said lower frame member.
