1. A vehicle latch (1) comprising:
a ratchet (15) movable between a release position, wherein the ratchet (15) is positioned to receive or release a striker (4), and at least one lock position, wherein the ratchet (15) is positioned to retain said striker (4); a releasable locking mechanism (16) cooperating with said ratchet (15) for actuating said ratchet (15) between the release position and the at least one lock position, said releasable locking mechanism including a primary pawl (25) movable between a ratchet checking position, wherein the primary pawl (25) is positioned to engage and keep said ratchet (15) in the at least one lock position, and a ratchet release position, wherein the primary pawl (25) permits the movement of said ratchet (15) out of said at least one lock position, an auxiliary ratchet (26) operatively connected to said primary pawl (25) and movable between an enabling position, in which the primary pawl (25) is enabled to move to said ratchet checking position, and a disabling position, in which the auxiliary ratchet (26) positions the primary pawl (25) to said ratchet release position, and a secondary pawl (27) movable between an auxiliary ratchet holding position, in which the secondary pawl (27) is positioned to hold said auxiliary ratchet (26) in said enabling position, and an auxiliary ratchet release position, in which the secondary pawl (27) is positioned to permit movement of said auxiliary ratchet (26) to said disabling position; an electrically-operated actuator (6) for engaging and automatically moving said secondary pawl (27) to said auxiliary ratchet release position and said auxiliary ratchet (26) to said enabling position; an inside emergency release lever (5) for manually moving said primary pawl to said ratchet release position independent of said electrically-operated actuator (6); and a back-up mechanism (7) for manually actuating said locking mechanism (16) independent of said actuation of said electrically-operated actuator (6) and said inside emergency release lever (5), said back-up mechanism including an outside emergency release lever (71) for engaging and moving said secondary pawl (27) to said auxiliary ratchet release position in response to rotation in a first direction thereby permitting movement of said ratchet (15) to release the striker (4) and an outside emergency lock lever (72) operatively coupled between said outside emergency release lever (71) and said auxiliary ratchet (26) for engaging and moving said auxiliary ratchet (26) to said enabling position in response to rotation of said outside emergency release lever (71) in a second direction opposite said first direction thereby maintaining said ratchet (15) in said at least one lock position to retain the striker (4); characterized by further comprising an inhibiting lever (81) operatively coupled between said ratchet (15) and said back-up mechanism (7) for movement to a disabling condition preventing interaction of said back-up mechanism (7) with said auxiliary ratchet (26) in response to movement of said ratchet (15) towards said release position. |
