Seat arm display monitor deployment mechanism

A display support apparatus for supporting a generally flat, video display from a passenger seat arm rest, the video display being of the type having a screen mounted on a front face, the arm rest being of the type having a recess for stowing the video display and the display support apparatus, comprising:

• an angled support arm having first and second ends, the support arm having a length at least as long as a diameter of the front face of the video display;
• first pivot means for pivotally attaching the video display to the first end of the support arm and having a first freedom of movement to permit the video display to be rotated around a first axis with respect to the support arm between a viewing position and a position in which a side of the video display and the support arm are alongside and substantially parallel with each other to form a generally rectangular configuration which is stowable in the arm rest recess, the first pivot means including a first pivot block having a first pivot joint which provides the first freedom of movement and a second pivot joint which provides a second freedom of movement permitting the video display to be rotated around a second axis that is horizontal so that the video display can be positioned for optimum viewing by a viewer sitting in the seat;
• and
• second pivot means for pivotally attaching the second end of the support arm to a front portion of the arm rest to allow the support arm and display means to be rotated into and out of the arm rest recess;
• wherein the second pivot means comprises a second pivot block having a third pivot joint which provides a third freedom of movement permitting the support arm and the video display to be rotated around a third axis that is horizontal and perpendicular to the arm rest and a fourth pivot joint which provides a fourth freedom of movement permitting the support arm to be rotated around a fourth axis that is perpendicular to the third axis, the support arm forming a first acute angle .PSI..sub.1 with the fourth axis.

• and
• second pivot means for pivotally attaching the second end of the support arm to a front portion of the arm rest to allow the support arm and display means to be rotated into and out of the arm rest recess;
• wherein the second pivot means includes a second pivot block having a third pivot joint which provides a third freedom of movement permitting the support arm and the video display to be rotated around a third axis that is horizontal and perpendicular to the arm rest and a fourth pivot joint which provides a fourth freedom of movement permitting the support arm to be rotated around a fourth axis that is perpendicular to the third axis, the support arm forming a second acute angle .PSI..sub.1 with the fourth axis, the first acute angle .PSI..sub.2 being approximately equal to one-half the second acute angle .PSI..sub.1.

A display apparatus for attachment to a passenger seat, comprising:

• a video display having a screen mounted on a front face;
• an arm rest attachable to a passenger seat and formed with a recess for stowing the video display;
• a support arm having first and second ends, the support arm having a length at least as long as a diameter of the front face of the video display;
• first pivot means for attaching the video display to the first end of the support arm, the first pivot means having a first freedom of movement so that the video display can be rotated around a first axis with respect to the support arm to a position in which a side of the video display and the support arm are alongside and substantially parallel with each other to form a generally rectangular configuration which is stowable in the arm rest recess, the first pivot means including a first pivot block having a first shaft protruding therefrom and extending into a hole in the support arm for providing the first freedom of movement, the first pivot block having a second shaft protruding therefrom for providing a second freedom of movement that permits the video display to be rotated around a second axis that is horizontal so that the video display can be positioned for optimum viewing by a viewer sitting in the seat, the first shaft and the second shaft forming a first acute angle .PSI..sub.2 ;
• and
• second pivot means for attaching the second end of the support arm to a front portion of the arm rest, wherein the second pivot means permits the support arm and the video display to be rotated from a position inside the recess to a position outside the recess so as to be viewable by a viewer sitting in the seat.
