Definitions

  • the subject matter disclosed herein relates generally to the field of seats and personal space design, both within and without passenger transportation vehicles, and specifically to the inferiors of such vehicles, and even more specifically to passenger seats that may be employed particularly in vehicle interior's environment, airport lounges or healthcare environment. However, it is to be understood that the invention is not limited to those environments.
  • a travelling seat or a seat designed for prolonged usage, that such seat comprises a seat pan, a seat back, and a pair of armrests positioned laterally with respect to the seat pan.
  • the seat back is mounted to the seat pan for pivotal movements between an upright position (wherein the seat back extends vertically upwardly relative to the seat pan) and a reclined position (wherein the seat back extends substantially horizontally relative to the seat pan).
  • the seat back In order ⁇ o provide a comfortable sitting, the seat back must provide a number of ergonomic properties. This includes appropriate support for the back of the person to be seated at various parts of his back in longitudinal direction but also appropriate support for the shoulders and arms, which involves taking into account parameters such as the width and the shape of the seat back.
  • armrest are necessary is advantageously exploited by using the armrest to include a foldable fable, entertainment controls, etc., this usually implies the seat portion to be narrower or the seat as a whole to be wider.
  • the appropriate support for the back in a sitting position may not be the same as a comfortable support for the person's back in a horizontal bedding position.
  • the support of the seat back since the seat back is also to be used in the horizontal bedding position, the support of the seat back must also be adapted and optimized for sleeping. For this reason it is necessary to make compromises in the type of support that a seat back will provide which results in a non-optimal solution for upright sitting or a non-optimal solution as a horizontal bed.
  • An example is the use of single seats that do recline into a flat position, sometimes less than the optimal 180 degree flat position.
  • the seat may be adequate in width as a seat, it is typically inadequate in width and/or length as a bed for the average size person. If the seat is adequately contoured as a seat, it is often inappropriate to use this contouring as a bed, resulting in an economically poor bed.
  • the seat in the horizontal position may be adequate as a bed, it is typically inadequate as seat, it being too wide, too soft and/or not sufficiently contoured to offer acceptable support and comfort. This is typically the solution offered in corporate or executive aircraft, and also for airline travel in transport category aircraft.
  • Another example is a combination of two reclinable single seats to be transformed into a bed.
  • a sofa also called a 'divan'
  • the divan can be extended in width, to provide adequate space to be used as a bed.
  • the prior art single seats typically use fixed foam cushions for the seat pan and for the seat back.
  • the leg rests are typically lightly cushioned with fixed foam, which results that the cushion hardness/softness is more or less uniform from the seat back to the leg rests.
  • Many seats including passenger seats, have an extendable footrest or leg rest installed thereon for the comfort of the person to be seated.
  • the footrest is actuated by a controller located on the seat armrest or by the reclining mechanism of the seat. When actuated, the footrest extends from its stowed, retracted position to the extended in use position and vice versa.
  • Those leg rests generate pressure point on lower members, i.e. the calf, the foot sole, etc. generating discomfort for the person to be seated as well as potential blood circulation disorder when a person is to be seated for long periods of time.
  • An armrest i.e. for a passenger transportation seat, is typically designed as a rectangular volume, positioned sideways and upright, with an upper surface typically parallel to the seat pan, upon which to place an arm.
  • the armrest may incorporate a pocket, with an optional lid, and/or it may incorporate a foldaway table, which fits vertically into the armrest.
  • the armrest may have a small horizontal surface that can be deployed from within the armrest, typically to place a beverage holder such as a small glass or similar.
  • An armrest may include a variety of cup holders or container holders utilized for supporting cups, cans or other beverage containers, which are selectively accessible to the person to be seated. Many of these container holders have been stored in armrest assemblies. A full lid or cover on the armrest is raised and a cup holder mechanism is removed from inside of the armrest and secured outwardly of the armrest. The lid of the armrest may be closed with the cup holder extending from the armrest.
  • the problem with these types of holders is the difficulty of accessing the holder, i.e., the user must manoeuvre several components to properly position the cup holder to receive a cup or container. Another example of a cup holder slides out from within the armrest and from the front face thereof.
  • ancillary equipment such as entertainment systems, table surface, storage places, etc.
  • the entertainment system or the table are built in the seat structure.
  • the entertainment system or the table can also be put away outside of the seat structure ⁇ o allow greater variety of designs.
  • the storage place is usually provided overhead or included inside of the shell space in front of the seat. Both solutions can easily give a feeling of confinement to the seated person.
  • the present invention addresses the disadvantages of multi-function seats from prior art by providing a solution in which the support provided by the seat is on one hand optimal for upright sifting but on the other hand also optimal for horizontal bedding. Furthermore, the invention provides various embodiments that allow the improvement of the sitting or sleeping experience, like various intermediate positions between a fully upright and a horizontal bedding position, a shell to provide for a sense of privacy while keeping the flexibility of physical communication, etc. An optimized intermediate position is called the relax position for future reference herein.
