Outdoor Living & Lifestyles - Possible to "re-strap" a patio chair?

I have four patio chairs. They are several years old old but have very attractive and very solid metal frames, with thick plastic (vinyl?) straps across the seat and back which (naturally) holds the person in place. The frames are in excellent condition with no rust or other damage so I'd like to keep them.

The problem is the plastic/vinyl straps. I stored the chairs in the garage over the winter, but a shelf fell and a heavy can landed right on the chairs. The cold (and age, no doubt) made the straps brittle; when the can landed on the chair it snapped several of the straps, rendering at least two of the chairs un-sittable.

I would like to remove the straps and "re-strap" the chairs, if at all possible. Has anyone done this, or have any idea where to begin?

Depends on how the strapping is attached. Used to be fairly common to redo the old style webbed lawn chairs.

The strapping on the old style mentioned above was held in place with a screw at each end of the strap. Re-strapping was done by using the old strap as a pattern to cut the new one. A double 45 degree fold at each end made the webbing strong enough to hold the screw.
