420:"I took some garbage to the dump one day, saw a box spring frame, and thought, 'That would make a perfect fin,'" he said. "The first design was just one long fin in the middle at the back of the sled. It didn't work. Then I cut that fin in two and put one piece on either side at the back of the sled. That worked great."
223:
The toboggan is directionally symmetrical so it can move either head first or foot first. When empty or with a light load, it can be handled by one person alone. With a full load or a well secured person in it, it requires two rescuers on skis who can take much of the weight of the load off the

A brake chain under the downhill end controls speed in steep terrain when pressure is applied to the front spars which proportionally affects the location and length of the chain to regulate the braking effect. A line attached to the toboggan secures it to a rescuer.

Several patrollers saw an old
European mountain rescue film showing an akja, a boat like sled with handles fore and aft, used in mountain rescue work in Bavaria . In 1958, the patrol borrowed an akja from a climbing group and modified the handles for patrol

In summer, toboggans can be used as an alternative to stretchers when on rough terrain. For longer distances on trails or other grounds, a centrally-placed wheeled axle carries a large proportion of the patient's weight.

Another problem
Bennett overcame was how to engineer an effective braking system. He said he was testing his design one day when it suddenly started to pick up speed at an alarming rate before he managed to regain

and the edges of the lower surfaces have three central stiffening skids. The straight bars, often made of steel pipe, lower the contour of the lower space and end with large oval rings about twice hip width.

After securing the injured person, she is transported to a point where evacuation by vehicle can occur. The rescue toboggan and patient can be carried by ambulance on roads or by a rescue helicopter.
427:
Bennett's solution was to install a chain under the sled's nose that contacts the snow only when the operator pushes down on the poles used to pull the sled. The resulting friction stops the sled.
231:
There are one and two piece toboggans. The latter is divisible so it can be carried on a backpack. The bars can be removed to carry the basket in a vehicle or on ski lifts and snowcats.

Bennett said much of the time involved in developing his sled was focused on constructing a fin system to keep the sled behind the operator, as opposed to sliding away down the hill.
