INDEPENDENT INTERNAL AND EXTERNAL DOOR LATCH ACTUATION MECHANISMS
A latch system (50) includes an actuation module (52) having first and second actuation mechanisms (110, 90). The first actuation mechanism (110) includes a first handle (98), a lock tab (100) and an inner rod (92) coupled together. The second actuation mechanism (90) includes at least one second handle (76), a conversion block (80) and an outer rod 68) coupled together, with the outer rod (68) and the conversion block (80) each having a slot (86). At least one latch module (54) has a retractable latch. A control cable (56) connects the conversion block (80) and the latch module (54) such that rotation of the conversion block (80) in a first direction retracts the latch. A lock (58) is operably engagable with the lock tab (100) to selectively allow and prevent rotation of the inner rod (92). Rotation of the inner rod (92) in the first direction rotates the conversion block (80). Rotation of the outer rod (68) in the first direction rotates the conversion block (80) without rotating the inner rod (92).
