A distance between the first and/or the second thigh engaging part and the trunk engaging part is settable. An abduction angle of that thigh engaging part is settable. The distance and the abduction angle are coupled such that a first set distance between that thigh engaging part and the trunk engaging part is coupled with a first set abduction angle and a second set distance different from the first set distance is coupled with a second set abduction angle different from the first set abduction angle. ## Claims ### Claim 1 An orthosis comprising: an engaging part arranged to operatively enclose a body part of a user, the engaging part including: an intermediate part; a first enclosing part bendably pivotally connecting to a first end of the intermediate part about a first rotational axis; a second enclosing part bendably pivotally connecting to a second end of the intermediate part about a second rotational axis; a bistable element bendably pivotally connecting to the first enclosing part about a third rotational axis and bendably pivotally connecting to the second enclosing part about a fourth rotational axis, the bistable element consisting predetermined first and second stable conditions in which the bistable element is urged, the first stable condition is arranged to maintain the first and second enclosing parts in an open position for placing the body part into the engaging part, and the second stable condition is arranged in a closed position by maintaining the first and second enclosing parts enclosing the body part. ### Claim 2 (depends on 1) The orthosis according to claim 1, further comprising an arm upon which the engaging part is secured. ### Claim 3 (depends on 2) The orthosis according to claim 2, wherein the intermediate part adjustably connects to the arm, the first enclosing part extending freely from the arm. ### Claim 4 (depends on 3) The orthosis according to claim 3, wherein the intermediate part is connected to a first coupling part connected to the arm. ### Claim 5 (depends on 2) The orthosis according to claim 2, wherein the first enclosing part is arranged to move relative to the arm when moving from the first and second stable conditions. ### Claim 6 (depends on 1) The orthosis according to claim 1, wherein the bistable element includes at least one resilient element pivotally connected to the first enclosing part. ### Claim 7 (depends on 6) The orthosis according to claim 6, wherein the first enclosing part is in a rotational position between the first and second stable conditions, the at least one resilient element is arranged to undergo compressive stress when in the rotational position. ### Claim 8 (depends on 1) The orthosis according to claim 1, wherein the bistable element includes at least one resilient element pivotally connected to the first and second enclosing parts. ### Claim 9 (depends on 8) The orthosis according to claim 8, wherein the first and second enclosing parts and the at least one resilient element are manufactured as one whole. ### Claim 10 (depends on 1) The orthosis according to claim 1, wherein the first and second enclosing parts and the intermediate part are manufactured as one whole. ### Claim 11 (depends on 1) The orthosis according to claim 1, wherein the first and second enclosing parts carry mating closures. ### Claim 12 (depends on 1) The orthosis according to claim 1, wherein the first and second stable conditions the bistable element has substantially no tensile stress or compressive stress. ### Claim 13 An orthosis comprising: an engaging part arranged to operatively enclose a body part of a user, the engaging part including: an intermediate part; a first enclosing part bendably pivotally connecting to a first end of the intermediate part about a first rotational axis; a bistable element bendably pivotally connecting to the first enclosing part about a third rotational axis, the bistable element consisting predetermined first and second stable conditions in which the bistable element is urged, the first stable condition is arranged to maintain the first engaging part in an open position for placing the body part into the engaging part, and the second stable condition is arranged in a closed position by maintaining the first enclosing part enclosing the body part; wherein the first and second stable conditions the bistable element has substantially no tensile stress or compressive stress, and the bistable element undergoes compressive stress between the first and second stable conditions. ### Claim 14 (depends on 13) The orthosis according to claim 13, further comprising an arm upon which the engaging part is secured. ### Claim 15 (depends on 14) The orthosis according to claim 14, wherein the intermediate part adjustably connects to the arm, the first enclosing part extending freely from the arm. ### Claim 16 (depends on 15) The orthosis according to claim 15 wherein the intermediate part is connected to a first coupling part connected to the arm. ### Claim 17 (depends on 14) The orthosis according to claim 14, wherein the first enclosing part is arranged to move relative to the arm when moving from the first and second stable conditions. ### Claim 18 (depends on 13) The orthosis according to claim 13, wherein the bistable element includes at least one resilient element pivotally connected to the first enclosing part. ### Claim 19 A method for securing an engaging part to operatively enclose a body part of a user, the engaging part including an intermediate part, a first enclosing part bendably pivotally connecting to a first end of the intermediate part about a first rotational axis, a second enclosing part bendably pivotally connecting to a second end of the intermediate part about a second rotational axis, and a bistable element bendably pivotally connecting to the first enclosing part about a third rotational axis and bendably pivotally connecting to the second enclosing part about a fourth rotational axis, the bistable element consisting predetermined first and second stable conditions in which the bistable element is urged, the method comprising the steps of: maintaining the bistable element in the first stable condition wherein the first and second engaging parts are open; placing a body part into the engaging part and pressing against the bistable element such that the bistable element goes into the second stable condition wherein the first and second engaging parts enclose the body part. ### Claim 20 (depends on 19) The method of claim 19, wherein the bistable element includes at least one resilient element projecting outside an outline of the intermediate part in the first stable condition, the bistable element will go from the first stable condition to the second stable condition as the body part presses against the resilient element.
