A latch arrangement for releasably retaining a striker, comprising a latch bolt shaped to retain the striker at a latching position, and to release the striker at an unlatching position of the latch bolt; a locking mechanism moveable between a locking position, at which it retains the latch bolt at its latching position, and an unlocking position, at which it allows the latch bolt to move to its unlatching position; means for linking the locking mechanism to a latch-opening external manual control such as a door handle; drive means coupled to the locking mechanism and/or the latch bolt for powered actuation thereof to latch or unlatch the locking mechanism and/or to drive the latch bolt to its latching position or to its unlatching position; a rotary clutch coupling the drive means to an electrical drive motor; and a clutch release mechanism drivingly coupled to the said external manual control such that operation of the latch-opening external manual control isolates the latch bolt and locking mechanism from the drive means.
A latch arrangement for an automotive door or other closure, comprising an electric motor coupled to a rotary driving and indexing member having at least one projection, the projection being resiliently displaceable, at least one actuation member arranged to be driven by a respective projection from the driving and indexing member, and means for controlling the electric motor selectively to position the driving and indexing member and thereby to drive the, at least one actuation member to perform a required action in the latch assembly for locking or unlocking the latch and/or completing closure of the door or other closure member.
A latch arrangement for an automotive door or other closure, comprising an electric motor coupled to a rotary driving and indexing member having at least one projection, at least one actuation member arranged to be driven by a respective projection from the driving and indexing member, and means for controlling the electric motor selectively to position the driving and indexing member and thereby to drive the at least one actuation member to perform a required action in the latch assembly for locking or unlocking the latch and/or completing closure of the door or other closure member, the driving and indexing member being resiliently biased towards neutral stable rotary positions thereof, so that it is driven preferentially to such positions from intermediate, unstable positions.
A latch arrangement for an automotive door or other closure, comprising an electric motor coupled to a rotary driving and indexing member having at least one projection, at least one actuation member arranged to be driven by a respective projection from the driving and indexing member, a means for controlling the electric motor selectively to position the driving and indexing member and thereby to drive the at least one actuation member to perform a required action in the latch assembly for locking or unlocking the latch and a locking member mounted for movement between a locking position and an unlocking position, the indexing member being coupled for selectively and independently driving the locking member, for electric door opening, wherein the projection is resiliently displaceable.
A latch arrangement for an automotive door or other closure, comprising an electric motor coupled to a rotary driving and indexing member having at least one projection, at least one actuation member arranged to be driven by a respective projection from the driving and indexing member, a means for controlling the electric motor selectively to position the driving and indexing member and thereby to drive the at least one actuation member to perform a required action in the latch assembly for locking or unlocking the latch and a locking member mounted for movement between a locking position and an unlocking position, the indexing member being coupled for selectively and independently driving the locking member, for electric door opening, wherein the driving and indexing member is resiliently biased towards neutral stable rotary positions thereof, so that the driving and indexing member is driven preferentially to such positions from intermediate, unstable positions.
A latch arrangement for an automotive door or other closure, comprising an electric motor coupled to a rotary driving and indexing member having at least one projection, at least one actuation member arranged to be driven by a respective projection from the driving and indexing member, a means for controlling the electric motor selectively to position the driving and indexing member and thereby to drive the at least one actuation member to perform a required action in the latch assembly for locking or unlocking the latch and a locking member mounted for movement between a locking position and an unlocking position, the indexing member being coupled for selectively and independently driving the locking member, for electric door opening, at least two locking member release levers connectable drivingly to respective external controls and coupled to the locking member for unlocking the locking member;
A latch arrangement for an automotive door or other closure, comprising an electric motor coupled to a rotary driving and indexing member having at least one projection, at least one actuation member arranged to be driven by a respective projection from the driving and indexing member, a means for controlling the electric motor selectively to position the driving and indexing member and thereby to drive the at least one actuation member to perform a required action in the latch assembly for locking or unlocking the latch and/or completing closure of the door or other closure member, and a locking member mounted for movement between a locking position and an unlocking position, the indexing member being coupled for selectively and independently driving the locking member, for electric door opening, and at least two locking member release levers connectable drivingly to respective external controls and coupled to the locking member for unlocking the locking member;
