I have a friend who has a disability. She tires easily and when she does she has a difficult time finding a place to sit when she needs it. I came up with this design that would be lightweight, removable, secure, could be hand washed, and would not be in the way when attached. The seat portion was recycled car seat harness from a child safety seat.
Step 1: Gather tools and materials
In this instructable I used
seam ripper (not pictured)
length of car seat harness webbing
1" flat nylon webbing
Heavy duty upholstry thread
4 1" welded steel D rings
8 1" welded steel O rings
4 3/4" electrical conduit claps (dipped in plastic dip prior to use)
To attach to walker I used
flat headed screwdriver
Step 2: Decisions of size
Decide how large you want the seat portion. I chose to make this seat for an adult so I wanted it fairly large.
Step 3: Cutting side lengths
Step 4: More cutting
Cut another 2 lengths of the wider webbing. Melt ends to prevent fraying. I chose 16" lengths. Insert the lengths into the looped ends and sew together using a straight stitch with machine. Sew only on outside edge and go forward and reverse 4-5 times.
Step 5: Cutting supports
Step 6: Cutting more supports
Step 7: Weaving
Weave the webbing through the longer supports alternating each. Sew using a straight stitch on opposite side. Repeat with all straps. Be sure to stitch forward and reverse 4-5 times.
Step 8: Reinforcment
Reinforce all intersections using a straight stitch. Take care to not stitch the looped ends closed.
The seat is mostly completed. Set aside.
Step 9: Cutting thinner webbing
Step 10: Cutting more thinner webbing
Step 11: Sewing O rings
Step 12: Threading O ring straps
Step 13: Threading longer straps
Step 14: Reinforce ends and close loops
Step 15: Attaching to walker
Thread double straps through D ring.
Loop around and come back to O rings.
Thread through O rings.
Loop back around and thread through 1 O ring. This should lock straps in place. Adjust as needed.
