1,214,885. Door latch. FRITZ KEIPER. 23 Sept., 1968 [23 Sept., 1967], No. 45149/68. Heading E2A. A motor vehicle door latch mechanism comprises a keeper to be fixed to a door post and a latch to be fixed to a co-operating door, a bolt mounted in a latch plate of the latch in a manner such that when the door is closed the bolt co-operates with or of two contact faces of the keeper in either a safety latch position or a fully latched position, the bolt and a plate provided on the inner end of the bolt taking up different positions relative to the latch plate in the safety and the fully latched position, and a first release member which can be operated to move the bolt into a release position necessary to open the door and can also be moved to an ineffective position to lock the latch, projections ion the plate and the first release member being provided which prevent the release member moving into its ineffective position when the latch is in the safely latched position. The latch is generally similar to that disclosed in Specification 1,214,884 but the first release member 42 has a projection formed as a pin 77 and the plate 37 has a projection formed by its bent ends 78, 79. In the fully latched position (Fig. 4) member 42 can be raised, the pin 77 passing between ends 78, 79, to the ineffective position where lug 43 cannot contact lug 41. In the safety latched position (Fig. 6) the plate is in a position where end 79 lies in the path of pin 77 to prevent the release member rising to its ineffective, locked, position.
