  • Head support on hack of seat Figure 1 illustrates a head support 10 supported on the back of a seat 12.
  • the illustrated seat has a configuration typically used in economy class of aircraft. Seats on domestic flights are usually either 17.2 or 18 inches wide (43.7 or 45.7 cm). On longer flights, economy-class seats on wide-bodied planes are often slightly larger, up to 18.5 inches (47.0 cm). Another relevant dimension is the "pitch" or the distance between rows of seats. In economy, the industry standard is 32 inches (81.3 cm) from the back of one seat to the back of the seat behind it. By comparison, the pitch on long haul flights in business class is 38 inches (96.5 cm) or more, while first class pitch ranges anywhere from 60 to 89 inches (152.4 to 226.1 cm).

  • the backing plate 20 may be integrally formed in the seat 12. Alternatively, for example for a retrofit, the backing plate 20 may be attached to the back of the seat 12. Attachment options may include snap fasteners, industrial strength VelcroTM, hooks and screws.

  • the support 26 is a flexible band or cradle.
  • the flexible support 26 is stretched taut between the first side panel 14 and second side panel 16 when the side panels 14, 16 are approximately orthogonal to the back plate 20.
  • the flexible support 26 thus inhibits the further rotation of the two side panels 14, 16.
  • the support cradle is formed from a strong yet flexible woven fabric such as polyester or Kevlar, it can simply be folded up and stowed in a recess defined between the side panels when they are closed.
  • the head support 10 has an arrangement Whereby the side panels 14, 16 may be held by the backing plate 20 when the head support 10 is in the stowed mode.

  • Velcro strip 22a is positioned on the backing plate 20 and Velcro strip 22b is positioned on the first side panel 14.
  • the patches 22(a) and 22(b) contact .one another, thereby holding the first side panel 14 against the backing plate 20.

  • Passenger 18, seated in seat 28 is shown using head support 10 positioned on the back of seat 12 which is in the row of seats in front of seat 28.
  • the passenger's head is placed on the flexible support surface 26.
  • the weight of the passenger's head depresses the support surface 26, thereby pulling the side plates 14, 16 closer together and applying pressure to the passenger's S
  • the head support 10 in the restraining mode provides a safety measure for the passenger's head, for example during an emergency landing on water.
  • Figure 6 illustrates relative positions of seats 12 and 28.

  • the head support has an adjustment mechanism such that the head support can accommodate a range of head sizes.
  • side panel 214 is pivoted to backing plate 222 and side panel 216 is pivoted to backing plate 220.
  • backing plates 220, 222 may be moved relative to one another in the plane of the device 210, Moving the backing plates 220, 222 has the effect of shifting the side restraints 214, 216 relative to one another. Consequently, the dimensions of the head support in the receiving and restraining mode may be adjusted to different head sizes.
  • the range of movement is limited by retaining plates 280, 281 positioned at outer edges of the device 210.

  • release knob 250 When release knob 250 is pressed, for example by a passenger wishing to adjust the position of plates 220, 222, the knob 250 forces release links 260, 261 apart from one another along the groove in which the links are positioned.
  • An end portion of each of the links 260, 261 is angled and acts on a flange on dent pins 230, 231 respectively.
  • the action of the links 260, 261 on the flanges of dent pins 230, 231 presses the pins against their respective springs 240, 241 , thereby releasing the pins 230, 231 from serrations 290, 291.
  • release knob 251 may be pressed to force release links 262, 263 apart from one another, thereby pressing dent pins 233, 232 against springs 243, 242 respectively. Pressing release knob 251 thus disengages pins 233 and 232 from the serrations 293, 292 respectively.
  • the backing plates 220, 222 may be moved relative to one another to change the dimensions of the head support.

Abstract

Le dispositif de support de tête décrit permet de soutenir une personne (18) voyageant dans un véhicule, le dispositif comprenant un premier élément de retenue latéral (14), un second élément de retenue latéral (16) et un support (26) défini entre les premier et second éléments de retenue latéraux. Le dispositif est déplaçable d'un mode de réception, dans lequel le dispositif est configuré pour recevoir la tête de la personne sur le support entre les premier et second éléments de retenue latéraux, vers un mode de retenue, dans lequel les premier et second éléments de retenue latéraux sont en contact avec la tête pour soutenir la personne contre les mouvements latéraux. Le dispositif de support de tête peut être monté sur un siège (12) dans un avion.
