PCT No. PCT / CA97 / 00941 Sec. 371 Date Aug. 16, 1999 Sec. 102(e) Date Aug. 16, 1999 PCT Filed Dec. 10, 1997 PCT Pub. No. WO98 / 26144 PCT Pub. Date Jun. 18, 1998A hood latch assembly (10) has a housing (14) having a mouth (13). A ratchet (16) is pivotally mounted within the housing (14) to cooperate with the mouth (13) to pivot between an open, a secondary closed and a primary closed condition for receiving, engaging and cinching a keeper of a striker (80). The ratchet (16) is biased to the open condition. A pivotally mounted primary pawl (18) is biased for engagement with the ratchet (16) to releasably retain the ratchet (16) in the primary closed condition. A pivotally mounted secondary pawl (62) is biased for engagement with the ratchet (16) to releasably retain the ratchet (16) in the secondary closed condition. The secondary pawl (62) has a release lever (20) which rotates between a deployed position and a retracted position. As the ratchet (16) engages the striker (80), the ratchet (16) will rotate in a latching sense from the open condition to the secondary closed condition. As the ratchet (16) further rotates from the secondary closed to the primary closed condition, fully engaging the striker (80), the secondary pawl (62) follows the ratchet (16), allowing the release lever (20) to rotate from a deployed position to a retracted position. Upon release of the primary engagement by disengaging the primary pawl (18), the ratchet (16) will rotate from the primary closed to the secondary closed condition. The secondary pawl (62) will follow the ratchet (16) rotating the release lever (20) from the retracted position to the deployed position. The operator then manipulates the release lever (20) to release the ratchet (16), allowing the ratchet (16) to rotate from the secondary closed to the open condition.

The invention relates to a rotating catch lock, wherein a closing member (10) interacts with a catch (20), which can be rotated between a closing position accommodating the closing member (10) and an open position which releases said member. The catch (20) is force-loaded (22) in an open position and is held by a spring-loaded (33) rotating latch (30) in the close position. Said latch (30) is moved by a motor (50) between the locking position retaining the catch (20) and a stand-by release position in which the spring-loaded latch (30) is propped up by the catch (20) as long as it remains in an open position. In order to use small compact motors (50), the invention provides that the stored energy (61) exerted by an energy storage mechanism (60) is transmitted to the latch (30) via a storage lever (40). Normally, the latch (30) is shifted into its stand-by position by the storage lever (40). When the latch (30) is in a stand-by position, the storage lever (40) is supported on a control tappet (51) which is rotationally driven by the motor (50). The motor (50) can be driven by an electrical control logic in both a forward mode (56) unloading the energy storage (60) and a reverse mode (56') loading the energy storage (60), i.e. in opposite directions. In the reverse mode (56') the control tappet (51) releases the latch (30), moves towards the storage lever (40) and guides it back into a starting position which corresponds to the stand-by position of the latch (30).
