Abstract: The chair has a seat that folds down about a horizontal axle 24 and which is intended, in particular, to equip halls that receive the public, such as lecture theatres and/or show halls. This chair comprises at least an underframe having an essentially longitudinal axis 14 and to which a backrest 16 may be fixed, and with respect to which a fixed horizontal axle 24 is determined. The seat 20 comprises a first part 32 projecting forwards with respect to the horizontal axle 24, and a second part 30 projecting towards the underframe 12. The underframe 12 contains a gas strut 40, one end 48 of which is fixed to the underframe 12, and the other end 50 of which is fixed to the second part 30 of the seat 20.

Abstract: A process for supplying fuel to an internal combustion engine of the multi-cylinder type with controlled fuel injection and comprising a controlled fuel vapor recovery system. During predetermined operating phases of the engine, the fuel injection is stopped for a given period, while the fuel vapors trapped in the recovery system are recycled into an intake circuit of the engine.

Abstract: A structure which resists dynamic forces, forming a mounting for a seat of an air transport craft and a seat having such a structure comprising front and rear feet, a front anchorage, an energy absorption device, and a stop mechanism. The front and rear feet are articulated at their upper ends on the seat framework, so that each can pivot about a horizontal and transverse pivot axle. The front anchorage comprises a joint having a traverse horizontal pivot axle, which allows the front foot to pivot forwards from its normal position about the joint pivot axle. The energy absorption device extends between the lower front anchorage and the upper part of the rear foot, but at a distance from the upper rear joint. The energy absorption device includes a stop mechanism for preventing the forward pivoting of the rear foot about its lower rear anchorage on the fixed structure of the craft.
