CS 22.785 Seats and safety harnesses ED Decision 2008/008/R (a) Each seat and its supporting structure must be designed for an occupant weight in accordance with [CS 22.25(a)(2)](#_DxCrossRefBm2056272040) and for the maximum load factors corresponding to the specified flight and ground conditions including the emergency landing conditions prescribed in [CS 22.561](#_DxCrossRefBm2056272171). Each seat and its supporting structure must also be designed to withstand the reaction to the load specified in [CS 22.397(b)](#_DxCrossRefBm2056272132). (b) Seats including cushions may not deform to such an extent that the pilot when subjected to loads corresponding to [CS 22.581](#_DxCrossRefBm2056272177) and [CS 22.583](#_DxCrossRefBm2056272178), is unable to reach the controls safely, or that the wrong controls are operated. (c) Each seat in a sailplane must be designed so that an occupant is comfortably seated, whether he wears a parachute or not. The seat design must allow the accommodation of a parachute worn by an occupant. (d) The strength of the safety harness must not be less than that following from the ultimate loads for the flight and ground load conditions and for the emergency landing conditions according to [CS 22.561(b)](#_DxCrossRefBm2056272171) taking into account the geometry of the harness and seat arrangement. (e) Each safety harness installation must be designed so that each occupant is safely retained in his initial sitting or reclining position under any acceleration occurring in operation. (f) Each seat and safety harness installation must be designed to give each occupant every reasonable chance of escaping serious injury under the conditions of [CS 22.561(b)(1) and (b)(2)](#_DxCrossRefBm2056272171).
