Seat with a reclining back and an armrest

A seat having a seat cushion and a seat back, the seat back being changeable in angular position with respect to the seat cushion, the seat comprising:

• (a) a side bracket secured to the seat back and having at least one hole extending therethrough;
• (b) an armrest pivotally connected to the side bracket and thereby being variable in angular position with respect to the seat back, the armrest having a set of holes spaced in a direction of angular movement of the armrest;
• and
• (c) at least one tab movably extending through the hole of the side bracket and thereby engaging the side bracket, the tab being selectively movable between a locking position in which part of the tab is positioned in any one of the holes of the armrest and an unlocking position in which the tab is positioned out of the holes of the armrest, the tab being thereby in and out of engagement with the armrest when the tab assumes the locking and unlocking positions respectively, whereby the armrest can be fastened to and released form the seat back when the tab assumes the locking and unlocking positions respectively, the tab being operative to selectably fix the armrest in any one of a plurality of preset angular positions with respect to the seat back which correspond to positions of the holes of the armrest respectively, whereby a change of the hole of the armrest in which the part of the tab is positioned causes a change of the preset angular positions in which the armrest is fixed.
