Abstract
Abstract A device for supporting a patient on a lift apparatus includes a generally rigid seat portion foldably connected to the lower end of a generally rigid back portion. A main support yoke has an upper cross bar adapted for connection to a lift apparatus and a pair of depending yoke arms connectable to the back portion at a medial position thereon. A pair of dual arm hangers are pivotally suspended from the upper cross bar for supporting opposite sides of the seat portion. Both the yoke arms and hangers may be rigid members which are length adjustable to retracted positions for transferring a patient into confined quarters such as an automobile. Whereas the device is connectable to a lift apparatus by a single connection to facilitate lifting and lowering of a patient, a pair of stabilizer bars are provided for securing the device during transport.

Claim 10
Independent Claim
204 words
A device for supporting a patient on a lift apparatus comprising, a generally rigid back portion, a generally rigid seat portion foldably connected to a lower end of said back portion, a main support yoke including an upper cross bar, and a pair of yoke arms extended downwardly from opposite ends of said cross bar, means for supporting said cross bar on said lift apparatus, means for pivotally connecting lower ends of said yoke arms to said back portion at a medial position thereon, a pair of dual arm hangers pivotally connected to said cross bar and extended downwardly therefrom, and means for securing lower ends of said dual arm hangers to opposite sides of said seat portion, a dual arm hanger including an elongated generally rigid seat support bar at the lower end thereof and a pair of hanger arms, said hanger arms having upper ends operatively connected to said cross bar and lower ends connected to said seat support bar at spaced apart positions thereon, said seat portion including a pair of flexible side flaps extended outwardly from opposite sides thereof, each side flap including a generally rigid coupling adapted for releasable connection to said seat support bar at spaced-apart positions thereon.
Claim 11
Independent Claim
153 words
A device for supporting a patient on a lift apparatus comprising, a generally rigid back portion, a generally rigid seat portion foldably connected to a lower end of said back portion, a main support yoke including an upper cross bar, and a pair of yoke arms extended downwardly from opposite ends of said cross bar, means for supporting said cross bar on said lift apparatus, means for pivotally connecting lower ends of said yoke arms to said back portion at a medial position thereon, a pair of dual arm hangers pivotally connected to said cross bar and extended downwardly therefrom, and means for securing lower ends of said dual arm hangers to opposite sides of said seat portion, said yoke arms being generally rigid and terminating at the lower ends thereof in inwardly extended portions, said back portion including socket means secured thereto at said medial position for receiving said inwardly extended portions.
Claim 12
Independent Claim
153 words
A device for supporting a patient on a lift apparatus comprising, a generally rigid back portion, a generally rigid seat portion foldably connected to a lower end of said back portion, a main support yoke including an upper cross bar, and a pair of yoke arms extended downwardly from opposite ends of said cross bar, means for supporting said cross bar on said lift apparatus, means for pivotally connecting lower ends of said yoke arms to said back portion at a medial position thereon, a pair of dual arm hangers pivotally connected to said cross bar and extended downwardly therefrom, and means for securing lower ends of said dual arm hangers to opposite sides of said seat portion, said yoke arms being generally rigid and terminating at the lower ends thereof in inwardly extended portions, said back portion including socket means secured thereto at said medial position for receiving said inwardly extended portions.
