Claim 11

A personal video assembly for a passenger seat, comprising: a console mounted adjacent to the seat; a video display monitor; an arm having a longitudinal axis and first and second end portions; a first joint means connecting the monitor to the first end portion of the arm for allowing the monitor to pivot relative to said axis with a first predetermined resisting torque; a second joint means connecting the second end portion of the arm to the console for allowing the arm to pivot relative to the console, said second joint comprising: a housing connected to the second end portion of the arm and having a bore formed therethrough which extends perpendicular to said longitudinal axis; a shaft which is supported by the console and rotatably received in said bore; a plurality of first clutch discs having central holes through which the shaft fittingly extends, the first clutch discs being keyed to the shaft; a plurality of second clutch discs having central holes through which the shaft fittingly extends, the second clutch discs being keyed to the housing and alternating with the first clutch discs along the shaft; and spring means for pressing the first and second clutch discs together to provide said second predetermined resisting torque; and a third joint means connected between the first and second joint means for allowing the monitor to pivot about said axis with a third predetermined resisting torque.

Claim 12

A personal video assembly for a passenger seat, comprising: a console mounted adjacent to the seat; a video display monitor; an arm having a longitudinal axis and first and second end portions; a first joint means connecting the monitor to the first end portion of the arm for allowing the monitor to pivot relative to said axis with a first predetermined resisting torque; a second joint means connecting the second end portion of the arm to the console for allowing the arm to pivot relative to the console, said second joint comprising: a housing connected to the second end portion of the arm and having a bore formed therethrough which extends perpendicular to said longitudinal axis; a shaft which is supported by the console and rotatably received in said bore; a plurality of first clutch discs having central holes through which the shaft fittingly extends, the first clutch discs being keyed to the shaft; a plurality of second clutch discs having central holes through which the shaft fittingly extends, the second clutch discs being keyed to the housing and alternating with the first clutch discs along the shaft; and spring means for pressing the first and second clutch discs together to provide said second predetermined resisting torque; and a third joint means connected between the first and second joint means for allowing the monitor to pivot about said axis with a third predetermined resisting torque.

Claim 13

A video assembly as in claim 9, in which: the shaft comprises: a small diameter portion which fittingly extends through the holes of the first and second clutch discs; and a large diameter portion which rotatably fits in said bore; the second joint means further comprises a journal which rotatably fits in said bore and has a central hole through which the small diameter portion of the shaft fittingly extends; the first and second clutch discs are disposed between the large diameter portion of the shaft and the journal; and the spring means is disposed between the large diameter portion of the shaft and the first and second clutch discs.

Claim 14

A video assembly as in claim 10, in which: the spring means comprises a plurality of compression springs which extends parallel to the shaft and are angularly spaced from each other about the small diameter portion of the shaft.
