Definitions
- the invention relates to a lock for a hood, in particular a bonnet, of a motor vehicle having a locking mechanism with a rotary latch and at least one pawl, a lock holder that can be engaged with the locking mechanism and a catch hook, the catch hook having a locking contour with a closed position and a Has pre -lock position.
- Hoods, bonnets, hoods and similar locking devices on motor vehicles are provided with additional safety measures if there is a risk that the hood will open by itself when the locking system is opened.
- Movably arranged on the motor vehicle components such as doors, flaps or bonnets are held in their closed position by means of a locking system or lock.
- the locking systems have a locking mechanism, which is usually provided with a first catch and a main catch. If the locking mechanism is now unlocked by the operator of the motor vehicle, the movable component can be moved out of the closed position and opened.
- the movable component such as preferably a motor hood
- external influences such as a driving wind
- catch hooks or locking hooks are used. Those hooks secure the hood when the locking mechanism is opened, whereby an additional interaction with the hood lock is required to open the hood completely in order to be able to open the hood completely.
- a hood or ceiling closure for a motor vehicle with a pre-lock and a closing lock has become known.
- a swivel latch together with a locking hook or lock holder, secures the hood in its closed position.
- the lock holder moves from a closed latched position into a pre-latched position.
- the locking hook runs through a Z-shaped slot in the swivel latch and is held in the pre-locking position.
- Only after another manual intervention in the swivel latch is it possible to completely disengage the engine hood from the swivel latch. To do this, the operator must manually reach into a bent lug on the pivot latch and move the locking hook out of the Z-shaped slot on the pivot latch.
- the object of the invention is to provide an improved hood lock for a motor vehicle.
- it is an object of the invention to create a way to provide an overall more compact design when interacting with the lock holder age with the motor vehicle lock.
- a lock for a hood, in particular a hood, of a motor vehicle which has a locking mechanism with a rotary latch and at least one pawl, a lock holder that can be brought into engagement with the locking mechanism and a catch hook, the catch hook having a locking contour with a closed position and a pre-locking position, and the catch hook being able to be brought into a closed position by means of the lock holder in interaction with the locking contour, the Closing position defines a lowered position of the catch hook in relation to a pre-locking position of the catch hook.
- the construction of the lock according to the invention now makes it possible to provide a motor vehicle lock that requires reduced installation space when the lock is in a closed position.
- the catch hook can be moved into a position in which the catch hook can be brought into a lowered position. If the catch hook functions in a pre- locked position in the usual way, so that the lock holder engages with the catch hook, the lock holder, in interaction with the locking contour, moves the catch hook when the locked position is reached in such a way that the catch hook moves from a pre-locked position to a closed position is pivoted.
- the catch hook is pivoted out of the closing direction of the lock holder.
- the lock is preferably used for a hood, in particular a bonnet.
- the construction of the lock according to the invention can also be used wherever a fishing hook is used in a lock.
- These can be covers, for example for a convertible top, flaps for luggage compartments or shelves, to name just a few areas of application.
- Catch hooks are used where external influences can cause the hood to open by itself.
- the catch hook is preferably used with a hood in the front area of a motor vehicle. After unlocking the ratchet, the ratchet releases the lock holder so that a hood could be opened. If, for example, the locking mechanism is unintentionally opened while the vehicle is being driven, the wind could open the hood completely. In order to avert danger to the operator of the motor vehicle or the occupants, the lock holder is held by the catch hook and at least one further action is necessary to open the hood completely.
- the locking mechanism comprises a rotary latch and at least one pawl, the rotary latch being engageable with the lock holder and the pawl locking the rotary latch in the latching position during closing.
- locking mechanisms with a first position and a main position or only with one main position are used.
- the main locking position of the locking mechanism defines the closed position of the bonnet for proper operation of the motor vehicle. If the locking mechanism is unlocked, for example by means of an inside operating handle in the passenger compartment and via a Bowden cable which is in engagement with the hood lock, the lock holder moves into a release position or a pre- locking position. In the pre-locked position, the catch hook holds the lock holder and at least one further manual or electrical actuation is necessary to release the catch hook from engagement with the lock holder. A maximum of safety is thus provided in the motor vehicle.
- the catch hook is continuously engaged with the catch hook during the closing movement of the hood.
- the catch hook has a locking contour via which the lock holder can move the catch hook from an open position of the hood into a pre-locking position and from the pre-locking position into the main locking position or closed position. If the main locking position is mentioned here, this means the closed position or locking position of the locking mechanism.
- the closed position is the position that the catch hook assumes in the main latching position of the locking mechanism or the closed position of the hood.
- the lock holder moves the Fangha ken during the closing of the lock and allows here at a snapping into the catch hook or a pivoting of the catch hook in a closed position.
- the catch hook is pivotably mounted on an axis.
- the axis of Fangha kens can be a pivot axis of the catch or the pawl.
- the locking contour of the catch hook has a first control contour for inserting the lock holder
- a control contour serves to enable the lock holder to be inserted into the pre-locking position.
- the lock holder moves the catch hook from the starting position in a linear closing movement around the pivot axis of the catch hook, so that a pointed contour at one end of the first control contour allows the lock holder to drop into the pre- locking position. If the hood is closed carefully, i.e. at low speed, the hood only moves into the pre- locked position. In the pre- locked position, however, the hood is already secured in such a way that the motor vehicle can be used without endangering the vehicle occupants.
- the locking contour has an additional control contour for pivoting the lock holder into a locking position
- a further advantageous embodiment of the invention can be achieved.
- the catch hook is advantageously pivoted in a matching direction by the first control contour and the further control contour.
- the further control contour ensures that the catch hook is pivoted beyond the pivoting angle for reaching the pre-locking position, so that the part of the catch hook for the pre- locking position is pivoted out of the closing direction of the lock holder.
- the catch hook no longer blocks a movement of the lock holder.
- the lock holder and in particular the length of the lock holder can be shortened in front of some way. This also results in shorter engagement conditions between the hood and the lock, so that overall a more compact design can be assumed.
- the catch hook pivots so far out of the range of movement of the lock holder that only the control contour of the catch hook has to be gripped by the lock holder.
- the lock holder only has to grip around the control contour of the closed position in order to move the hood into the fully closed position.
- the catch hook In the closed position, the catch hook is pivoted out of the range of movement of the lock holder, so that the control contour for the pre- locking position is flush with a housing of the lock.
- the catch hook can be pivoted in the closing direction by means of the additional control contour.
- a pivoting of the catch hook takes place around the bearing point of the catch hook, so that the catch hook can be arbitrarily positioned according to the length of the control contour can be pivoted far out of the direction of movement of the lock holder.
- the catch hook is pivoted so far out of the movable position of the lock holder that the part of the catch hook for the pre- locking position is moved out of the movement path of the lock holder. This allows the hood to be moved closer to the lock.
- the further control contour describes a circular path.
- a circular path in the catch hook makes it possible for the catch hook to be pivoted continuously and consistently quickly, i.e. with a defined movement, out of the movement path of the lock holder.
- the radius of the circular path can be selected in such a way that a pivoting movement matched to the closing movement can be set, so that the catch hook can be moved easily, i.e. with optimal force ratios for pivoting the catch hook, and with a defined pivoting speed can be.
- the catch hook can be pivoted in a first closing direction by means of the first control contour, in an opposite direction by means of a third control contour and again in the first closing direction with the further control contour.
- the structure or arrangement of several control contours for guiding the catch hook can also ensure safe movement of the catch hook if, for example, the catch hook is not spring-loaded.
- the control contours make it possible for the catch hook to be moved into a pre- locked position, a closed position and a ne open position can be transferred.
- the mounting of the catch hook is then designed in such a way that the catch hook moves in a first closing direction due to the force of gravity.
- the catch hook can be inserted without springs by means of the lock holder.
- the control contours in combination with the dead weight and the bearing of the catch hook, then make it possible for the lock holder to be transferred through the control contours into an open position, a pre-locked position and a closed position.
- the catch hook can be mounted eccentrically in the lock in relation to an insertion direction of the lock holder.
- the lock holder moves on a linear movement path during its transfer into the main locking position of the locking mechanism of the lock.
- the hood is attached to the motor vehicle with hinges, whereby the lock holder can be pivoted about the pivot axes of the hinges.
- motor vehicles that are equipped with one or two lock holders or one or two locks.
- the lock holder moves into the lock by means of a linear movement in the direction of insertion.
- the direction of insertion here defines a center line, which also represents the reference line for an eccentric arrangement of the catch hook in the lock.
- the bearing point of the catch hook is superimposed on a direction of movement of the catch hook when inserting the lock holder into the pre-locking position ent opposite direction eccentrically in the motor vehicle lock ge.
- the bearing point of the catch hook can be arranged on a right-hand side of the center line be assumed, in which case a pivoting movement of the catch hook to reach the pre- locking position via the first control contour performs a pivoting movement in a counterclockwise direction.
- the lock holder pivots the catch hook when it reaches the catch hook in the opposite direction through the first control contour on the catch hook.
- the catch hook again snaps back in a clockwise direction, at least in certain areas, so that the catch hook can grip around the lock holder and hold it securely.
- the catch hook is spring-loaded in this embodiment given by way of example in the clockwise direction.
- the arrangement of several control contours also makes it possible to insert or release the lock holder without spring preload.
- the catch hook closes flush with the housing of the motor vehicle lock in the closed position.
- the catch hook does not protrude beyond the lock, so that it is possible for the lock to approach the hood directly.
- the approach of the cover to the lock is not hindered by the catch hook, since the catch hook was pivoted out of the range of movement of the lock holder.
- the lock holder itself can have a smaller extent and it can be assumed that the lock and lock holder weigh less overall.
- FIG. 1 shows a plan view of a motor vehicle lock and a view of a catch hook in an initial position before the hood has been closed
- Figure 2 shows the position of the catch hook during the locking process before the lock holder has reached the pre-locking position
- FIG. 3 the pre- locking position of the lock holder in engagement with the catch hook
- Figure 4 shows the position of the lock holder before the lock holder has reached the closed position
- FIG. 5 shows the catch hook in a closed position of the hood, as well as a main locking position of the locking mechanism.
- 1 shows a basic representation of a motor vehicle lock 1 in a top view of a catch hook 2 and a lock holder 4 attached to a bonnet 3.
- the bonnet 3 is shown in an open position, so that the bonnet 3 can move freely.
- the Fangha ken 2 is in an initial position in which the lock holder 4 faces a first control contour 5 .
- the Fangha ken 2 is about a pivot axis 6 around movable in the motor vehicle lock 1 added.
- the catch hook has a Steuerkon structure 7, through which the lock holder can initiate a movement in the catch hook 2.
- the figure shows the ge opened bonnet 3, the motor vehicle lock 1 in an unlocked situation and the catch hook 2 in its initial position.
- the lock holder 4 moves linearly along a center line M and moves the catch hook 2 as it moves along the center line M.
- the catch hook 2 is spaced from the stand A in the motor vehicle lock 1.
- a focal point 8 of the catch hook 2 lies between the bearing point 6 of the Fangha kens 2 and the center line M.
- gravity acts on the catch hook, which loads the catch hook 2 in the direction of arrow F by its gravity F counterclockwise.
- a spring element not shown, is arranged on the catch hook 2, the spring element spring-biasing the catch hook 2 in the direction of the arrow P clockwise.
- the catch hook 2 can also be transferred into a pre-locked position and a closed position by the interaction of the control contour 7 with the lock holder 4 .
- FIG. 1 A first control contour 5, a further control contour 9 and a third control contour 10 can be seen in FIG. 1.
- the hood is open.
- FIG. 2 now shows the position of the catch hook 2, in which the catch hook 2 is located when the lock holder 4 was moved in the closing direction, ie in the direction of the arrow PI.
- the lock holder 4 has moved along the first control contour 5 and has moved the catch hook 2 counterclockwise in the direction of the arrow P2. If the lock holder 4 moves further in the direction of the arrow PI, the lock holder reaches a pointed end 11 of the catch hook 2 and between the pointed end 11 and the third control contour 10.
- Either a spring preload or the third control contour 10 then moves the catch hook 2 back in Direction of arrow P clockwise, so that if the hood 3 is not completely closed and the hood 3 springs back from the lock holder 4, it can engage an upper end 12 of the catch hook 2. Due to the spring preload or the third control contour 10, the lock holder 4 thus reaches a pre- locking position, as shown in FIG. Even if the hood 3 is not completely closed, the catch hook can hold the lock holder 4 securely and ensure safe use of the motor vehicle. Consequently, FIG. 3 shows the pre- locking position of the catch hook 2. As can be clearly seen, the catch hook 2 protrudes beyond the motor vehicle lock 1.
- the projection of the catch hook 2 or the upper end 12 of the catch hook 2 beyond an upper end 13 of the motor vehicle lock 1 is marked with "Ü". /or act on the lock holder, held in the pre-locked position. If the lock holder 4 is now moved further in the direction of the arrow PI, the lock holder 4 engages the further control contour 9. The further control contour 9 requires that the catch hook 2 is again moved counterclockwise in the direction of the arrow P2.
- FIG. 5 shows the position of the lock holder 4 in which the motor vehicle lock 1 holds the lock holder 4 in a main latching position.
- the lock holder 4 is held in the main latching position and on the other hand, the further control contour 9 arranged in a circle has ensured that the catch hook 2 is pivoted further in the direction of arrow P2, to the extent that the upper end 12 of the catch hook 2 is below the level E, that is below the upper end 13 of the motor vehicle lock 1 is located.
- the lock holder 4 can thus be much closer or the bonnet 3 can be moved much closer to the motor vehicle lock 1 because the upper end 12 of the catch hook 2 is no longer in the movement path M of the lock holder 4 .
- the other control contour 9 has pivoted the catch hook 2 counterclockwise so far that the catch hook or at least the upper end 12 of the catch hook does not protrude beyond an upper end 13 of the lock. It can thus be realized a compactly constructed interplay of lock holder 4 and motor vehicle lock 1, which in turn has a positive effect on the constructive freedom and the technical design of the motor vehicle as a whole.
