Definitions
- the present invention belongs to the field of manufacture of aircraft cabin fittings, for general aviation, commercial aviation, helicopters or military aviation. It relates more particularly to the production of an aircraft seat supporting one or more passengers and equipped with shock absorbing means for the passenger in the back seat (front impact), or at the seat ( shock down).
- Aircraft seat volume is a concern that addresses the increased number of passengers transported each year.
- By reducing the unit volume of the seats it is possible to reduce the spacing between two rows of seats and to increase the number of passengers that can take place in aircraft, or conversely, to increase the space for each passenger or for the goods.
- a better filling of the aircraft makes it possible, with a constant flow of passengers on an airline, to reduce the number of flights: the fuel saved reduces the amount of greenhouse gas emissions by the same amount.
- the shape of the seat combines the comfort of the passenger, including the backrest, and possibly the seat, flexible (s), and the mechanical strength of the skeleton, in order to meet the standards in force in the carriage of passengers by air. It dissociates the structural resistance, provided by a single rigid element forming the skeleton, and the seat and the backrest of the passenger, made of a flexible material.
- the object of the invention is therefore to provide the aircraft seat according to the invention damping means of the passenger placed behind the seat, in the event of a frontal impact of the aircraft, the head of the passenger being behind tilting against the back of the seat back in front of him.
- a damping means placed at the level of the seat makes it possible to restrain the passenger in the event of an impact towards the bottom of the aircraft.
- the main object of the invention is a seat for aircraft whose mechanical strength of its structure is provided by a skeleton, including in particular voids at the seat and possibly the backrest.
- the invention comprises a reinforcement strip of energy absorbing textile, located, in a first embodiment of the invention, slightly set back from the backrest, and placed behind the latter, to cushion the tilting of the head of the rear passenger in the event of a violent frontal impact of the aircraft.
- a single reinforcing tape can be placed at the seat to cushion the impact down, very important in the case of helicopters.
- the seat can be equipped with these two bands.
- the energy absorbing textile consists of a single-strand structure knitting.
- the knitting it is advantageous for the knitting to be of the jersey stitch type.
- a variant of this first embodiment is to use several son in parallel for knitting.
- the energy absorbing textile is woven with weft yarns and warp yarns.
- the weft yarns and the warp yarns have approximately the same strength.
- the wire is in fact a stretched elastic wire surrounded by a loose but high tenacity yarn.
- the stretched elastic yarn is advantageous for the stretched elastic yarn to be made of polyamide (for example Nylon®).
- the materials used to form the energy-absorbing textile of the reinforcing strip are from the group consisting of polyetherimide fibers, polyetherketone fibers, high molecular weight polyethylene fibers, meta and para-aramid fibers, natural fibers (flax, hemp, jute ...) and polyamide fibers.
- FIGS. 7A and 7B views relating to a variant of the yarn used for weaving the reinforcement strip of the seat according to the invention.
- the seat according to the invention is formed of a skeleton 1, which can be molded, formed or assembled according to the choice of material, and two flexible parts forming the backrest 2 and possibly the seat 3.
- a seat for the transport of passengers by aircraft fulfills several functions: dynamic resistance to shocks and strong acceleration, passenger seat and backrest, support for various accessories (foldable shelf, magazine rack, armrests, ). Each of these functions corresponds to a seat element that can be separately optimized to reduce the volume and total weight of the seat.
- the first function of the seat is structural resistance. This function is in the case of the invention provided by a skeleton. Skeleton means the rigid part of the seat that gives it structural strength: the backrest 2, the seat 3 and the securing points of the accessories do not play this role.
- the skeleton of a seat is usually articulated, but perhaps lightened by becoming rigid.
- This figure 1 shows a minimal skeleton 1 of the seat, formed of a hollow tubular structure. The attachment points are located on the part of the seat linked to the floor of the aircraft.
- the two central vertical bars 9 in the center of the folder can be directly connected to the attachment points of the seat to the floor of the aircraft in the case of a non-articulated file, to minimize the weight of the skeleton.
- This attachment to the floor of the aircraft can take place directly, for example by insertion of the two lower bars 10 of the skeleton 1 in rails formed in the floor of the aircraft, or indirectly, by attachment to a rigid intermediate structure. The latter is stowed to the floor of the aircraft.
- a rigid aircraft structure makes it easier to install and maintain the seats.
- the second function of the seat is the reception of the passenger.
- the backrest 2 and seat 3 of the seat are the parts directly in contact with the passenger and may not participate in the structural strength of the seat. These parts are attached to the seat structure itself, but can be much thinner, to minimize the total weight of the seat.
- the backrest 2, and possibly the seat 3, are made using a flexible material. A high-tenacity polyester weave, for example, may be suitable.
- the mesh of the fabric provides an ergonomic shape, particularly marking the hollow of the back and hips.
- Figure 2 shows the addition of the backrest 2 and the seat 3 to the skeleton 1 of the seat. These parts are very light, made of a flexible material such as weaving of polyester fibers.
- a strip of flexible material 4 is added behind the backrest 2 because the material constituting the latter does not sufficiently dampen the passenger in case of violent shock.
- An identical band (not shown) may optionally be added under the seat 3 if the seat must withstand significant shocks down.
- Figure 3 shows the same seats, still in exploded view, but seen from behind. It includes the skeleton 1, the backrest 2, the seat 3, and the reinforcing strip 4 placed behind the backrest 2. It is provided with a display 8 that can be used to place, among other things, magazines or instructions of security.
- the main technical feature of the invention is the use of the reinforcing strip 4 which must be much more deformable than the backrest 2, and also much more resistant.
- the backrest 2 must have a void in the middle of the skeleton 1 or have a concave rear face to provide a space for the deformation of the reinforcing strip 4 during the impact.
- the principle of producing the fabric constituting the reinforcing strip 4, and the band possibly added under the seat, is to combine a very strong fiber with little stretch, that is to say of high tenacity or breaking strength. , to an elastic shaping, in order to amortize, without shock, a shock.
- the textile is deformed to match the shape of the object to stop, namely the head of the passenger on the seat behind the seat on the back of which is placed the reinforcement strip considered.
- the textile resists the object in a uniform way, thus absorbing the shock. Indeed, the energy transferred during the shock is spread over the entire contact area between the textile and the object, not only at the point of impact. The pressure exerted greatly decreases, limiting the constraints that the object undergoes.
- the chosen fiber is agglomerated into yarns to allow textile shaping.
- Several fibers can be agglomerated within a single wire.
- the simplest yarn is composed only of
- PEEK polyethercetone
- nylon polyamide
- natural fibers flax, hemp or jute
- polyethylene polyethylene
- Toughness measures the force that must be exerted in traction to break a fiber. The higher the toughness, the more resistant the fiber is to tensile forces important. If the textile has to have additional qualities, it is possible to mix several fibers in the same thread, adding, for example,
- Nomex meta-aramid fibers
- Knitting uses only one thread for the textile surface, while weaving mixes several weft and warp threads.
- the weave can be used to mix several types of yarn, but limits the strength of the textile, because the thread discontinuities are points of weakness of the textile.
- Knitting ensures excellent mechanical strength to the resulting textile, but limits the possibilities of shaping. Indeed, the knitted fabric can not be cut and sewn to other parts of textiles, without the mechanical performance of the knit are altered.
- the jersey type mesh makes it possible to obtain a relatively deformable textile.
- the jersey point is to make a row at the place, then a row upside down.
- the wire 10 is wrapped around itself, from one line to another, the loops leaving large gaps in the textile surface.
- the son loops When a tension is exerted on the knitted fabric, the son loops can be deformed, imparting a certain elasticity to the assembly. If the voltage is high, and exceeds the mesh deformation possibilities, the yarn is stressed in tension, and the tenacity of the yarn is brought into play. The fact that a single yarn is used for the entirety of the knit prevents the textile from tearing from a breaking point of the wire, or at the interface between two wires.
- an alternative embodiment of the knit shown in Figure 1 is to knit several son 20 in parallel for the same textile.
- the mesh remains the same, but instead of using only one thread, several threads constitute each mesh.
- Each of the yarns 20 is continuous over the entire surface of the textile, but the properties of the yarns can be combined. In particular, the fire resistance, the mechanical strength or the water-repellency is thought.
- This variant is simpler to implement than to mix fibers within the same single wire, but does not mix so intimately different fibers.
- the use of fine threads makes it possible to increase the interactions between each fiber. There again, the jersey stitch can be used.
- the other alternative of the main idea, according to the invention is to weave together different threads which are the weft threads 40 and the warp threads 50.
- the weft 40 and warp threads 50 may be different, but it must be ensured that the mechanical strength of each of these weft threads 40 and warp thread 50 is equivalent.
- one direction may be preferred over the other.
- the weaving can be relatively loosely and allow a certain clearance between the weft son 40 and warp 50. This game gives elasticity to the bonded textile, only rearrangement between the son and not to the elasticity of the fibers constituting the son.
- An exemplary embodiment may be a plain weave where the weft and the warp are
- polyamide nylon
- natural fibers lm, hemp or jute
- high-weight polyethylene yarn
- a central wire 60 is used which is elastic, while another high tenacity wire 62 surrounds it very broadly.
- the elastic thread 60 may be, for example, a nylon thread
- the high tenacity yarn 62 can be
- polyamide nylon
- natural fibers lm, hemp or jute
- high-weight polyethylene yarn a polyamide (nylon), natural fibers (lm, hemp or jute) or a high-weight polyethylene yarn
- the high tenacity yarn 62 is wrapped or twisted around the elastic yarn 60 which is central.
- the elastic thread 60 placed in the center, stretches, while the high-tenacity thread 62 at the periphery deforms, approaching the elastic thread 60.
- the tension exceeds the possibilities of deformation of the elastic wire 60, which is in the center, the high-tenacity yarn 62 is then stretched and then gives a very strong mechanical strength to the fabric thus formed.
- the cushioning of the head of a passenger on the back of the back of the front seat is all the more effective, the textile part is elastic.
- the cushioning of the passenger is at the seat of the seat, and is more effective than the band added under the seat is elastic.
- the cushioning is based on a transfer of the kinetic energy of the passage in elastic energy of the textile part.
- the shock of the passenger is minimized, ie the force transmitted to the passenger to go from the cruising speed to the stop, spreading the cushioning over a time range as large as possible.
- a sufficiently low elasticity constant which amounts to having a fairly elastic fabric, therefore allows the impact to be spread out over time and to minimize the feeling felt by the passenger.
- the textile can therefore withstand the shock of a passenger running at full speed, in the case of an aircraft crash, by frontal impact, or during a downward impact in the case of the band located under the seat.
- the breaking strength is generally low for elastic fibers. Elasticity is achieved by allowing individual filaments to slide relative to each other, within a single thread. The weak cohesion between the filaments is a problem, in the breaking strength because the individual filaments dissociate at low force levels. The use of very high threads
- ® toughness such as aramid fibers (Kevlar or
- Molecular weight allows to combine these contradictory characteristics of elasticity and tenacity, and this thanks to the shape of the elastic knit, or to the use of a mixed weaving.
- the knitting is a shaping of the wire mesh, using only one thread for all the textile.
- the use of a single large wire guarantees the mechanical strength of the assembly, avoiding the breaking points of the wire.
- the jersey stitch used makes it possible to obtain this elasticity by its structure, independently of the elasticity of the yarn.
- the use of a combination weave an elastic yarn and a loose high tenacity yarn makes it possible to achieve the same result.
- the use of an elastic structure and a high tenacity yarn makes it possible to combine a low deceleration for the passenger and an excellent mechanical strength of the textile part.
