A walker for assisting persons with varying degrees of physical ability is provided with an adjustable strap. A user opens a portion of the walker and enters the walker, and then the user closes the portion of the walker to enclose himself or herself in the walker. The user is positioned over an adjustable strap, and the adjustable strap is in an extended position. The adjustable strap may then be retracted such that a seat disposed on the adjustable strap rises and contacts the user to bear at least a portion of the user's weight.

The walker of claim 1, wherein the plurality of legs descends downwardly and at an angle perpendicular to the frame and wherein the distal end of the arcuate rear portion is unsupported by a lower rear portion disposed between the rear arcuate portion and the ground surface. 3. The walker of claim 1, wherein the plurality of legs operatively engage a plurality of wheels. 4. The walker of claim 1, further comprising: a lower front portion disposed between the frame and the ground, wherein at least one leg is connected to the lower front portion; anda lower arcuate rear portion disposed between the rear arcuate portion and the ground surface. 5. The walker of claim 1, wherein the retraction device automatically retracts the adjustable strap from the first length to the second length after a delay period, wherein the delay period begins after the arcuate rear portion selectively connects to the frame. 6. The walker of claim 1, wherein the first end of the adjustable strap is operatively connected to the retraction device at a single point, and the second end of the adjustable strap is connected to the frame at a single point and wherein a delay period is zero seconds. 7. A method for adjusting the strap of a walker, comprising: providing a walker, comprising: a frame partially enclosing an interior of the frame, the frame oriented generally horizontal to a ground surface;a plurality of legs connected to the frame and descending downwardly from the frame;an arcuate rear portion having a proximate end and a distal end, the proximate end rotatably connected to the frame, the arcuate rear portion extending outwardly relative to the interior of the frame;an adjustable strap having a first end, a second end, and a length between the first and second ends of the adjustable strap, wherein the first end and second ends of the adjustable strap are operatively connected to the walker;a seat disposed between the first end and the second end of the adjustable strap; anda retraction device positioned on the walker, wherein the first end of the adjustable strap is operatively connected to the retraction device, the retraction device retracts and extends the adjustable strap between a first length and a second length, the retraction device is electrically connected to a power supply supported by the walker, and a switch enables a person to control the wind and unwind operations of the retraction device;extending the adjustable strap to the first length to enable the person to enter the interior of the frame, while the adjustable strap is operatively connected to the retraction device and the frame of the walker and the arcuate rear portion is disconnected from the frame;receiving the person within the interior of the frame, wherein the person is centered over the adjustable strap and the seat, and wherein the adjustable strap is positioned between legs of the person;rotating the arcuate rear portion to selectively connect to the frame and enclose fully the interior of the frame; andretracting the adjustable strap from the first length to the second length, wherein the second length is shorter than the first length, and wherein the seat contacts the person and bears at least some of the person's weight. 8. The method of claim 7, wherein the changing the length of the adjustable strap automatically occurs a delay period after the rotating of the arcuate rear portion to enclose the interior of the frame and wherein the distal end of the arcuate rear portion is unsupported by a lower rear portion disposed between the rear arcuate portion and the ground surface. 9. The method of claim 8, wherein the delay period is zero seconds. 10. The method of claim 7, wherein the plurality of legs extend downwardly and at an angle perpendicular to the frame, wherein the distal end of the arcuate rear portion is unsupported by a lower rear portion disposed between the rear arcuate portion and the ground surface. 11. The method of claim 7, wherein the plurality of legs operatively and collectively engage more than four wheels, and wherein when the seat bears at least some of the person's weight, the seat bears between approximately 50% to 100% of the person's weight. 12. The method of claim 7, wherein at least a segment of the arcuate rear portion comprises a radius of curvature, and wherein at least a segment of the frame comprises a radius of curvature. 13. The method of claim 7, wherein the walker further comprises: a lower front portion disposed between the frame and the ground, wherein at least one leg is connected to the lower front portion; anda lower rear portion disposed between the arcuate rear portion and the ground. 14. A walker for assisting a user, comprising: a plurality of legs connected to a frame and descending downwardly from the frame;a rear portion having a proximate end and a distal end, the proximate end rotatably connected to the frame, wherein the rear portion rotates about the rotatable connection such that the distal end selectively connects to and disconnects from the frame, which fully encloses an interior of the frame;an adjustable strap having a first end, a second end, and a length between the first and second ends of the adjustable strap;a retraction device disposed on the rear portion, wherein the first end of the adjustable strap is operatively connected to the retraction device, wherein the second end of the adjustable strap is connected to the walker, wherein the retraction device retracts and extends the adjustable strap between a first length and a second length, wherein the first length is longer than the second length, wherein in a first operational mode the first length enables a user to enter the interior of the frame, while the adjustable strap is operatively connected to the retraction device and the frame of the walker and the rear portion is disconnected from the frame, and position the adjustable strap between legs of the user and in a second operational mode the adjustable strap is retracted to the second length, and wherein the retraction device is an electric motor that converts electrical energy to retract and extend the adjustable strap between the first length and the second length; anda seat disposed between the first end and the second end of the adjustable strap, wherein when the retraction device retracts the adjustable strap to the second length the seat contacts the user and bears at least some of the user's weight;wherein the plurality of legs descends downwardly at an angle perpendicular to the frame. 15. The walker of claim 14, wherein the rear portion is arcuate in shape, the arcuate rear portion extending outwardly relative to the interior of the frame being enclosed by the frame, wherein the first end of the adjustable strap is operatively connected to the retraction device at a single point, wherein the distal end of the arcuate rear portion is unsupported by a lower rear portion disposed between the rear arcuate portion and the ground surface, wherein the plurality of legs operatively engage a plurality of wheels, and wherein the plurality of wheels comprise more than four wheels. 16. The walker of claim 15, wherein the second end of the adjustable strap is connected to the frame at a single point and further comprising: a lower front portion disposed between the frame and the ground, wherein at least one leg is connected to the lower front portion; anda lower arcuate rear portion disposed between the arcuate rear portion and the ground surface, wherein the distal end of the arcuate rear portion is unsupported by the lower arcuate rear portion.
