Abstract
Abstract A closure and locking mechanism for the lid of a compartment receiving a foldable top and for a curved fabric-retaining member forming the rear termination of the foldable top; two locking devices are thereby provided disposed opposite one another for locking the foldable-top compartment lid in its closed condition as also a lock for locking the fabric-retaining member in its position in which the closed, unfolded top is stretched, which are all actuatable by way of a single remote control installation; the remote control installation thereby includes two entrainment members mounted on its pivot shaft, of which a first entrainment member is in operative connection with the nearer locking device by way of elongated aperture guidances while the other entrainment member is in operative connection with a bell crank by way of an angle rod and adjoining connecting rod; in addition to a Bowden cable leading to the second locking device, also an actuating linkage acting by way of a claw lever on a latching lever of the lock for the fabric retaining member is pivotally connected with the bell crank.
