The field of the invention relates to support surfaces attached to seat backs for passenger vehicles such as aircrafts.
Inside an airplane, space is very limited and therefore valuable. Airlines aim to optimize how they use the space to ensure they meet their profit goals and to achieve the required density level in economy class. To do this, the area allocated to each seat is typically minimized to be as small as possible, which can be uncomfortable for the passenger, especially for long flights. Often, a passenger will bring personal items with them to provide entertainment during the flight, but there is not always space to store those items so that they remain readily available for when the passenger desires to use them.
Conventionally, there are two locations in each economy class seat where the passenger can place his or her belongings. The first location is the tray table. When the tray table is deployed, the passenger may place his or her personal items on the tray table. These items are then readily available, but the space provided by the tray table may be insufficient depending on the number of personal items the passenger has or if the meal or drink service has arrived, which may result in the items needing to be relocated someplace else. Additionally, when the tray table is deployed, the surface of the tray table typically tends to be approximately horizontal to the floor, and thus there is not an appropriate surface on which to place and hold a tablet, cellphone, or other personal electronic device at an appropriate viewing orientation.
The second location where the passenger can place his or her belongings is the seat back pocket. However, this area does not always provide readily available access, e.g., if the tray table is deployed. Additionally, items can easily be forgotten when placed in the seat back pocket.
