Military abseiling in the Dülfersitz

The Dülfersitz (named after the mountaineer Hans Dülfer , who introduced it, sometimes also called Dülfern ) is an old abseiling technique used in climbing and mountaineering . The dulfer seat only uses the friction of the rope placed around the body , which is why no additional aid is required. This Abseiltechnik is no longer in use, because usually with eight descender is roped or other Abseilhilfen.

Advantages of the dulfer seat are that it can be abseiled without a climbing harness and it is a rope-friendly abseiling technique . The rope is not flexed like in the figure eight and other rope brakes, see also: carabiner seat , Saxon seat. Disadvantage: There is a lot of frictional heat ; the shoulder and thigh often get uncomfortably hot. Above all, the neck must be covered with a collar or similar. be protected from the rope and friction. The clothing is heavily used.

Abseiling in the Dülfersitz

  • The rope taken twice is picked up between the spread legs
  • The rope is wrapped around one thigh from the rear outside
  • Crossing the side of the chest, the rope is led to the opposite shoulder
  • The rope runs diagonally from the shoulder over the back to the braking hand. It's the hand next to the wrapped thigh.
  • Tension the rope under load
  • The front hand keeps the body in balance, the braking hand controls the rope entry
  • The descent begins
  • To hold the abseil, the braking hand is brought forward in front of the chest

Or in short, from top to bottom: left hand - right thigh - left shoulder - right hand. If practiced correctly, the dulfer seat is a safe abseiling method.

However, this technique is problematic when unforeseen events (falling rocks, cramps, etc.) occur. As soon as a hand lets go of the rope in a panic reaction, a fall is inevitable if no self-protection is used. However, additional securing by means of Prusik knots is possible.
