Definitions
- the present invention relates to a double-pull lock for a vehicle door and/or lid, particularly for the hood of a vehicle.
- a double safety lock for the hood of their vehicles.
- Such a type of locks is actuated by the user for a first time to obtain a partial opening, wherein the hood is lifted by a few millimeters (25-30 mm) and is still retained by the lock, and is actuated by the user for a second time in order to open and lift the hood completely.
- Double-pull locks This type of locks is generally known as “double-pull locks”.
- US8,419,114 discloses a lock for a vehicle hood that comprises a first catch that holds the hood in closed position, and a second catch that holds the hood in partially open position.
- the two catches are actuated by a cam connected to a release mechanism that is actuated by the user in the passenger compartment. In such a way, a first actuation of the release mechanism releases the first catch, and a second actuation of the release mechanism releases the second catch.
- Such a closing device is impaired by some drawbacks in terms of safety.
- the cam is inserted between the two catches and is connected to a cable actuated by means of a mechanical or electronic system. Therefore, such a closing device can be easily tampered and forced.
- the rotation of the cam that is pulled by the cable requires the exertion of a high force on the cable. Therefore, the mechanical actuation is rather cumbersome for the user, who needs to exert a certain force on an actuation lever connected to the cable of the cam.
- the electronic actuation requires the provision of an electric actuator with a certain power to exert a force that is adequate to pull the cable.
- DE102016117282 discloses a vehicle double-pull lock according to the preamble of claim 1.
- US2019/017291 discloses a vehicle double-pull lock provided with an ejection spring that pushes the catch and the striker.
- KR20150124850 discloses a complicated lock comprising a mechanism with a plurality of parts.
- WO201 5/077549 discloses a lock that is not a double-pull lock, wherein, after being disposed in closed position, the catch makes an extra downward travel, it being pushed by the striker.
- the purpose of the present invention is to eliminate the drawbacks of the prior art by disclosing a double-pull lock for a vehicle hood that is safe, versatile, reliable and easy to make and operate.
- the lock according to the invention is defined by claim 1.
- Fig. 1 is a top view of the lock according to the invention in a closing position
- Fig. 2 is an exploded view of three parts of the lock of Fig. 1 ;
- Fig. 3 is a view of the lock according to the invention during a first actuation
- Fig. 4 is a view of the lock according to the invention in an intermediate closing position

- actuation means such as a manually operated actuation lever or an electrically operated actuator.
- the second Bowden cable (8) comes out of the base plate (1 ) towards the left-hand side.
- the pawl (3) comprises a stop lever (35) that projects from the second arm (31 b) of the pawl towards the catch (2) in order to cooperate with the stop lever (25) of the catch.
- the striker (4) is locked in the fastening seat (22) of the catch.
- the catch (2) is in closed position and is locked by the pawl (3) that is in locked position.
- the first spring (5) has the arm (15) under the striker (4) and pushes the striker (4) in order to eject it from the slot of the base plate.
- the user In order to open the lock (100), the user performs a first actuation by pulling one of the Bowden cables (7, 8) of the pawl in the direction of the arrow F1. Consequently, the pawl (3) rotates around the second pivoting pin (P2), going from the locking position to the unlocking position shown in Fig. 3. The stop tooth (32) of the pawl releases the stop tooth (23) of the catch. Meanwhile, the second spring (6) is loaded.
- the catch (2) Being released from the pawl (3), the catch (2) can rotate around the first pivoting pin (P1 ) in the direction of the arrow F2, under the thrust of the first spring (5) that pushes the striker (4) that, in turn, pushes the catch (2), in such a way to partially disengage the striker (4) from the fastening seat (22) of the catch.
- the stop lever (25) of the catch is stopped against the stop lever (35) of the pawl, preventing the catch (2) from going to the completely opening position.
- the stop tooth (32) of the pawl is disposed in the fastening seat (22) of the catch between the second stop tooth (24) and the first stop tooth (23) of the catch.
- the striker (4) has made a travel of a few millimeters in the slot (10) of the base plate.
- the hood is in partially closing condition.
- the striker (4) has made an upward travel of a few millimeters, slightly lifting the hood, but the striker (4) is still retained in the fastening seat (22) of the catch, and the catch is locked by the pawl in intermediate locking position, preventing a total opening of the hood.
- the user performs a second actuation of one of the two Bowden cables (7, 8) of the pawl in the direction of the arrow F4, rotating the pawl around the second pivoting pin (P2).
- Such a rotation of the pawl determines a disengagement of the stop tooth (32) of the pawl from the second stop tooth (24) of the catch.
- the catch (2) is free.
- the arm (50) of the first spring pushes the striker (4) that in turn pushes the catch (2) that rotates in the direction of the arrow F5 until the opening position, wherein the striker (4) is out of the slot (10) of the box.
- the arm (50) of the first spring is stopped against the stop block (26) of the catch, pushing the catch (2) to the opening position.
- the arm (50) of the first spring (5) is stopped in an opening position, in front of the entrance of the slot (10) of the base plate, being stopped against an edge (12) of the base plate.
- the stop block (26) of the catch is disposed between the arm (50) of the first spring and a projection (13) of the base plate in such a way not to move from said position.
- the striker (4) is pushed inside the slot (10) of the base plate in the direction of the arrow F7, loading the spring (5) and pushing the catch (2) that rotates around the first pivoting pin (P1) in the direction of the arrow F8. Consequently, the cam surface (28) of the second stop tooth (24) of the catch slides on the cam surface (38) of the stop tooth of the pawl, and the pawl rotates in the direction of the arrow F9, in such a way that the stop tooth (32) of the pawl passes beyond the second stop tooth (24) of the catch.
