A passenger seat comprising (a) pivot shaft; (b) a passenger seat back comprising a recess, wherein the passenger seat back is pivotally coupled to the pivot shaft in at least one location; (c) a tray table assembly comprising: (i) a table body comprising at least one shaft; (ii) at least one arm comprising a first end and a second end, wherein the first end is pivotally coupled to the at least one shaft and the second end is pivotally coupled to the pivot shaft in a location interior with reference to the location where the passenger seat back is pivotally coupled to the pivot shaft; and (iii) at least one table stop comprising an end, wherein the at least one table stop is configured to couple to the at least one arm, and wherein the end of the at least one table stop is fixedly coupled to the pivot shaft in a location adjacent the location where the second end of the at least one arm is pivotally coupled to the pivot shaft characterised in that; the at least one table stop comprises a clamp having a substantially U-shaped configuration formed by a pair of legs and a base, the pair of legs extending along a notched section of the pivot shaft, and the base being shaped to substantially conform to a portion of the rounded surface of the pivot shaft; and the at least one table stop comprises a stop pin and the at least one arm comprises a stop pin receiver that is shaped to receive the stop pin, whereby the stop pin receiver allows the at least one arm to rotate from a stowed arm angle α' to a released arm angle β' such that when the at least one arm is positioned at the released arm angle β', an inner side of the stop pin receiver contacts the stop pin. (a) pivot shaft; (b) a passenger seat back comprising a recess, wherein the passenger seat back is pivotally coupled to the pivot shaft in at least one location; (c) a tray table assembly comprising: (i) a table body comprising at least one shaft; (ii) at least one arm comprising a first end and a second end, wherein the first end is pivotally coupled to the at least one shaft and the second end is pivotally coupled to the pivot shaft in a location interior with reference to the location where the passenger seat back is pivotally coupled to the pivot shaft; and (iii) at least one table stop comprising an end, wherein the at least one table stop is configured to couple to the at least one arm, and wherein the end of the at least one table stop is fixedly coupled to the pivot shaft in a location adjacent the location where the second end of the at least one arm is pivotally coupled to the pivot shaft characterised in that; the at least one table stop comprises a clamp having a substantially U-shaped configuration formed by a pair of legs and a base, the pair of legs extending along a notched section of the pivot shaft, and the base being shaped to substantially conform to a portion of the rounded surface of the pivot shaft; and the at least one table stop comprises a stop pin and the at least one arm comprises a stop pin receiver that is shaped to receive the stop pin, whereby the stop pin receiver allows the at least one arm to rotate from a stowed arm angle α' to a released arm angle β' such that when the at least one arm is positioned at the released arm angle β', an inner side of the stop pin receiver contacts the stop pin. (i) a table body comprising at least one shaft; (ii) at least one arm comprising a first end and a second end, wherein the first end is pivotally coupled to the at least one shaft and the second end is pivotally coupled to the pivot shaft in a location interior with reference to the location where the passenger seat back is pivotally coupled to the pivot shaft; and (iii) at least one table stop comprising an end, wherein the at least one table stop is configured to couple to the at least one arm, and wherein the end of the at least one table stop is fixedly coupled to the pivot shaft in a location adjacent the location where the second end of the at least one arm is pivotally coupled to the pivot shaft characterised in that; the at least one table stop comprises a clamp having a substantially U-shaped configuration formed by a pair of legs and a base, the pair of legs extending along a notched section of the pivot shaft, and the base being shaped to substantially conform to a portion of the rounded surface of the pivot shaft; and the at least one table stop comprises a stop pin and the at least one arm comprises a stop pin receiver that is shaped to receive the stop pin, whereby the stop pin receiver allows the at least one arm to rotate from a stowed arm angle α' to a released arm angle β' such that when the at least one arm is positioned at the released arm angle β', an inner side of the stop pin receiver contacts the stop pin.
