Lock assembly operated by pressurised medium especially for cabriolet vehicle roofs has blocking device ensuring first closing position is reached with first and second lock parts

摘要

The lock assembly has a first movable lock part (2) interacting with a second lock part (3). The first lock part has a simple-acting operating element (4) operated by pressurised medium and with a single connection (9) for supplying and discharging the pressurised medium. The operating element has an operating member (7) movable between a pushed-in end position and an extended end position and coupled to the first lock part so that when pressurised medium is supplied the first lock part is moved into an operating direction. A closing position is defined between the end positions from where during displacement of the lock part in the operating direction the two lock parts inter-engage. A mechanical resetting device (8) sets the first lock part back against the operating direction and a blocking device (15) blocks displacement of the first lock part against the operating direction so that the two lock parts remain engaged. The blocking device is disengaged on furth er displacement of the first lock part when pressurised medium is supplied Independent claim describes vehicle with movable roof with lock combination for locking roof edge
