The seat portion 66 is aligned with a lower edge of the backrest portion 68 and the seat portion 66 is positionable in a stored position having the seat portion 66 lying against the backrest portion 68. The seat portion 66 is positioned between each of the arms 24 on the front surface 22 of the cart 16 when the lift 44 is fully lowered thereby making it easier to position a non-ambulatory user in the chair 64.
A pair of arm rests 70 is provided and each of the arm rests 70 is pivotally coupled to the backrest portion 68 of the chair 64. Each of the arm rests 70 is spaced upwardly from the seat portion 66. Additionally, each of the arm rests 70 is positionable in a stored position having each of the arm rests 70 lying against the backrest portion 68. Each of the arm rests 70 can be pivoted laterally with respect to the chair 64. The chair 64 includes a seat belt 71 for securing the user in the chair 64 during lifting and lowering
A shelf 72 is provided and the shelf 72 is slidably coupled to the chair 64. The shelf 72 is positionable in an extended position extending laterally away from the chair 64. Thus, the user can be positioned on the shelf 72 to assist with sliding the user from the chair 64 onto the upper surface 14 of the bed 12. Moreover, the shelf 72 can be slid either to the right or to the left of the chair 64.
The shelf 72 includes a plurality of stops 73 that each engage the chair 64 to inhibit the shelf 72 from being extended so far as to be removed from the chair 64. The shelf 72 is slidably coupled to a bottom surface of the seat portion 66 of the chair 64. The shelf 72 is positioned beneath the seat portion 66 when the shelf 72 is positioned in a stored position. The shelf 72 may include a hinged section that is downwardly pivotable on the shelf 72. Thus, the hinged section of the shelf 72 can be downwardly pivoted to drop the user onto the bed 12 when the user is positioned on the shelf 72. The hinged section on the shelf 72 may have a depth of approximately 9.0 inches.
A pair of pivots 74 is provided and each of the pivots 74 is pivotally coupled to the cart 16.
