Abstract
Seating groups for passengers, for example in an aircraft cabin, are equipped with several seats having seat components supported on a support base on which the seat components, especially the seat sections are laterally slideable to make the seats wider when a passenger sits on a seat or narrower when a passenger is not sitting on a seat. The seat widening or narrowing is accomplished in several ways, for example, with the aid of a grooved shaft that operates as a spindle when turned by tilting a seat component, or by springs that vault upwardly when not loaded and spread when a passenger sits on a seat supported by the springs. The grooved shaft can be operated for example by an armrest or a seat section.
Claims6
A seating group comprising a plurality of passenger seats having together a group length, a support base supporting said passenger seats, each passenger seat comprising a number of seat components including at least a seat section and a backrest, said support base comprising at least one guide rail provided in common for all passenger seats of said seating group, a guide member interposed between said at least one guide rail and a respective one of said seat components, and a lateral shifting mechanism connected to at least one of said seat components for laterally shifting at least one of said seat components along said at least one guide rail in response to a movement of said at least one of said seat components connected to said lateral shifting mechanism so that said group length is temporarily reduced and a respective aisle width is temporarily increased, wherein said lateral shifting mechanism comprises a coupling device (19) operatively connecting neighboring seat sections to each other, and wherein said at least one seat component connected to said shifting mechanism comprises a tiltable armrest (6) rigidly secured to said coupling device so that tilting said armrest in one direction causes said lateral shifting of said at least one of said seat components to temporarily reduce said group length and tilting said armrest in an opposite direction restores said group length.
