Definitions
- Lock holder for a motor vehicle door lock having a lock holder plate, a lock holder bracket fastened on the lock holder plate, the lock holder bracket being designed with a locking bolt, a center piece and a connecting bolt, and A projection is arranged on the middle piece in the direction of a longitudinal extent of the middle piece.
- the lock holder usually interacts with a locking mechanism of an associated motor vehicle door lock.
- Lock holder and motor vehicle door lock generally define the motor vehicle door lock.
- the lock holder, in conjunction with the locking mechanism in the motor vehicle door lock ensures that the associated motor vehicle door is closed securely and reliably.
- the lock holder is usually connected to a motor vehicle body, for example a B or C pillar of the associated motor vehicle body.
- the motor vehicle door lock is found in the motor vehicle door to be locked. In principle, the reverse can also be done. Due to the primary locking function of the lock holder in conjunction with the locking mechanism in the motor vehicle door lock, on the one hand it is a particularly safety-relevant component, which on the other hand is exposed to particular loads, particularly in the event of an accident. In fact, the protection of vehicle occupants in the event of a side impact depends largely on how reliable the lock holder and the associated effective locks are able to absorb the attacking forces. Because here it is primarily important that the motor vehicle door remains closed so that safety devices provided in or on the motor vehicle door, such as side airbags, side impact protection, etc., can have the desired effect.
- the forces to be absorbed via the interaction between the motor vehicle door lock and the lock holder act directly between the locking mechanism contained in the motor vehicle door lock and the locking bolt of the lock holder bracket which engages with the locking mechanism.
- the locking mechanism is formed from a rotary latch and at least one pawl, whereby after the rotary latch engages, when the door element closes, the pawl engages in the striker of the lock holder and prevents the door element from being opened.
- the locking mechanism can have a preliminary detent and a main detent, which can be present in the door lock depending on the door element. Depending on the design of the locking mechanism, the respective locking position, i.e.
- main locking or pre-locking can be equipped with an opening or closing moment, so that a blocking lever can be used to secure the locking position.
- the locking parts are at least partially made of a metallic material, mounted in metallic axles and held on a metallic lock plate in the motor vehicle door lock.
- a lock holder for a motor vehicle door lock has become known, with a lock holder plate and a lock holder bracket attached thereto, the lock holder bracket being designed with a locking bolt, a center piece and a connecting bolt.
- the document suggests that the lock holder bracket is positively connected to the lock holder plate via at least one material-thickened area.
- the lock is used The part of the lock holder bracket or the locking bolt and/or the connecting bolt protruding from the holder plate is compressed.
- the lock holder plate is also equipped with a bulge, which ensures that compression caps formed on the underside of the lock holder plate as a result of the compression process can rest against the body at a distance from the locking bolt on the one hand and the connecting bolt on the other.
- the object of the invention is to provide an improved lock holder for a motor vehicle door lock.
- it is the object of the invention to improve the resilience of the lock holder and to increase the tear resistance of the system consisting of lock and lock holder.
- a lock holder for a motor vehicle door lock comprising a lock holder plate, a lock holder bracket fastened on the lock holder plate, the lock holder bracket having a locking bolt, a center piece and a connection - Bolts are formed and a projection is arranged on the center piece in the direction of a longitudinal axis of the center piece, the lock holder being designed at least in two parts.
- the design of the lock holder according to the invention now creates the possibility of designing the lock holder bracket to be individually adaptable to the loads and in particular the extreme loads in the event of an accident.
- the individual stresses in the event of an accident are particularly relevant to safety, as it must be ensured, especially in the event of an accident, that the doors, flaps or hoods remain closed.
- the side doors are particularly important because the occupants of the motor vehicle must be protected. Only in combination with the secure locking of the door can the other safety systems, such as seat belts and airbags, develop their full effect.
- the stresses in the event of a crash are extremely high and are simulated by tensile tests when designing the lock holder.
- the lock holder is subjected to a tensile test until it breaks in order to be able to determine, on the one hand, whether the specified specifications have been achieved and, on the other hand, to identify weak points so that an individual design of the lock holder is possible.
- This is where the invention comes into play in particular and shows a way to improve the resilience of the lock holder.
- the projection in the direction of the longitudinal axis of the center piece enables the rotary latch to be supported in the locking mechanism, with the two-part structure supporting the possibility of cost-effective production.
- the lock holder according to the invention does not only refer to a side door, but can also be used in the area of a hood, tailgate, sliding door, cover, folding bench seats, etc., just anywhere. where components used on the motor vehicle that are pivotable or movable must be kept secure in their position.
- the lock holder has a lock holder plate which is designed as a base for the lock holder bracket and which preferably has at least two bores by means of which the lock holder can be fastened to the motor vehicle or to the movable component.
- the openings in the lock holder plate preferably have a conical countersink, so that a flat surface with the lock holder plate can be achieved using suitable screws with a conical head.
- the lock holder plate can additionally have a fold, so that rivet heads of the lock holder bracket can be received in the fold, so that a flat attachment of at least a portion of the lock holder plate to the body is possible. The fold then accommodates the corresponding rivet heads of the lock holder bracket.
- the lock holder bracket can preferably be attached as a separate component to the lock holder plate, in particular can be attached in a non-detachable manner. Due to the two-part structure and in particular the separation between the lock holder bracket and the lock holder plate, the loads can be adjusted individually. A simple construction is possible because the lock holder plates are manufactured individually and can be formed, for example, as a stamped and bent piece, so that an advantage can be achieved, particularly in mass production.
- the lock holder bracket can be attached to the lock holder plate, whereby advantageous production is also possible here.
- the rotary latch comes into engagement with the center piece because the rotary latch shifts over the locking bolt in the direction of the center piece. Due to the projection on the center piece, not only the part of the rotary latch that encompasses the locking bolt, i.e. the load arm of the rotary latch, comes into engagement with the center piece, but also the part of the rotary latch that is arranged in front of the locking bolt, in other words the catch arm the rotary latch.
- the rotary latch is therefore supported on both sides of the locking bolt. on the one hand towards the middle piece and on the other hand towards the overhang. This means that overall increased support can be provided when the rotary latch and lock holder interact. This increases the load capacity of the door locking system.
- the locking bolt is preferably fixed at right angles, that is, in the direction of a normal to the lock holder plate on the lock holder plate.
- the middle piece extends essentially parallel to the lock holder plate, whereby an engagement area for the rotary latch in the lock holder bolt can be achieved.
- the connecting bolt is connected to the middle piece, which in turn extends from the middle piece to the lock holder plate.
- the connecting bolt can be straight or at least partially curved. However, it is also conceivable that the connecting bolt forms a slope starting from the center piece in the direction of the lock holder plate.
- the lock holder bracket has a mounting web, in particular a mounting web arranged parallel to the center piece.
- the mounting web extends along the lock holder plate and lies against the lock holder plate.
- the mounting web thus, like a preferred embodiment of the lock holder plate, has a flat extension in the area of the contact surface to the lock holder plate.
- the lock holder bracket can be connected to the lock holder plate using the mounting bar.
- the mounting web extends parallel to the center piece, so that there is an opening in the lock holder bracket that can be described as a substantially rectangular opening.
- An alternative opening shape can result, for example if the connecting bolt is designed at an angle or has an S-shape.
- the center piece and the mounting web preferably have the same cross-sectional areas. This has proven to be particularly advantageous in terms of resilience.
- Using the mounting bar increases the resistance to bending stress.
- a bending stress can act on the locking bolt in particular in the longitudinal direction of the vehicle or in the direction of a longitudinal extension.
- a coordinate system is usually placed in a motor vehicle for construction purposes.
- the y-axis forms the longitudinal direction of the vehicle
- the x-axis forms a transverse direction of the vehicle
- the z-axis forms a vertical in relation to the motor vehicle or the surface of the motor vehicle.
- the bending stress can thus be increased, particularly in the y and z directions.
- the mounting web is designed with mounting elements.
- At least one extension can be formed onto the lock holder bracket, which then extends through an opening in the lock holder plate and can be permanently connected to the lock holder plate, for example by means of reshaping.
- Two extensions are preferably formed on the lock holder bracket, which can be connected to the lock holder plate by means of forming, i.e. riveting.
- three extensions are formed on the lock holder bracket, and it is also conceivable according to the invention that, for example, an extension serves as an assembly aid, for example for inserting the lock holder bracket into the lock holder plate.
- the extensions or extensions on the lock neck are preferred.
- ter bracket is cylindrical, the extensions being insertable into holes in the lock holder plate.
- the lock holder bracket has a contour that can essentially be described as a rectangular shape.
- the center piece, the connecting bolt and the mounting bar can have a square shape, whereas the locking bolt has a round cross-sectional shape.
- the locking bolt has a round shape because the locking bolt engages with the rotary latch and by means of a rotary movement of the rotary latch.
- the projection, the middle piece, the connecting bolt and the mounting web have a square shape, which has proven to be particularly advantageous with regard to bending stress on the lock holder.
- the projection forms a contact surface for a rotary latch.
- the projection extends from the center piece beyond the locking bolt, the projection having a cross-sectional shape corresponding to the center piece.
- the protrusion forms a contact surface for the rotary latch.
- the projection extends so far beyond the locking bolt that the projection comes into engagement with a catch arm of the rotary latch.
- the projection preferably extends over the tentacle in some areas. In the event of an extreme load, i.e. in the event of an accident, the rotary latch can therefore also end up in a system with the protrusion.
- the projection and center piece form a common contact surface for the rotary latch.
- the middle piece and the projection can advantageously be arranged on a common plane, at least in relation to the contact surface for the rotary latch.
- the middle piece and projection thus form a common contact surface for the rotary latch.
- the center piece and the projection also extend laterally beyond the locking bolt, so that extensive contact with the rotary latch can also be achieved.
- the middle piece and the projection can provide a load surface which allows the rotary latch to lie flat in the event of an extreme load, so that a significant increase in the load capacity of the motor vehicle door lock can be achieved.
- the lock holder bracket is designed in one piece.
- the one-piece design of the lock holder bracket offers the advantage that increased load capacity can be achieved in the lock holder bracket.
- there are no stress peaks in the transition area between the different areas of the lock holder bracket since a one-piece structure has an optimized line of force.
- FIG. 1 shows a side view of a lock holder designed according to the invention in interaction with a rotary latch and a lock case
- Figure 2 shows the lock holder according to Figure 1 in the event of an external force, such as an accident
- Figure 3 shows a top view of the lock holder according to the invention from the direction of an arrow III from Figure 1.
- FIG. 1 shows a side view of a lock holder 1 designed according to the invention.
- the lock holder 1 has a lock holder plate 2 and a lock holder bracket 3.
- the lock holder 1 is shown in interaction with a rotary latch 4 and a lock case 5.
- 1 shows a main locking position, that is, a closed position of the motor vehicle lock, in which the rotary latch 4 extends around the lock holder, the rotary latch 4 being accommodated in the lock case 5 so as to be rotatable about an axis 6.
- the axis 6 is only shown in principle, with the axis 6 typically being arranged as shown in FIG. 3 in the closed state of the rotary latch 4.
- the lock holder bracket 3 is designed in one piece and has a locking bolt 7, a projection 8, a middle piece 9, a connecting bolt 10 and a central web 11.
- the side view of the lock holder describes a rectangular shape, with the rectangular shape being abstracted only by the inclination of the connecting bolt 10.
- the projection 8 extends from the middle piece 9 beyond the locking bolt 7, so that a projection 8 beyond the locking bolt 7 can be achieved.
- the lock holder bracket 3 is essentially square in shape, only the locking bolt 7 has a cylindrical shape.
- the rotary latch 4 surrounds the locking bolt 7 circumferentially, so that the locking bolt 7 rests on the rotary latch circumferentially in some areas. It can be clearly seen that a flat contact surface 12 for the rotary latch 4 can be achieved through the projection 8 and the middle piece 9.
- the projection 8 extends in some areas beyond the rotary latch and in particular a catch arm 13 of the rotary latch 4.
- the projection 8 can, for example, protrude 15 mm, preferably 10 mm, and even more preferably 8 mm beyond the tentacle 13.
- an impression 14 can be seen, which has an additional stabilizing effect on the lock holder bracket 3.
- the impression 14 extends essentially above an opening 15 formed by the lock holder bracket 3.
- the mounting web 11 lies flush against a surface 16 of the lock holder plate 2.
- the mounting web 11 and center piece 9 are arranged parallel to one another, as are the rotary latch 4 and the lock case 5 parallel to the center piece 9, mounting web 11 and lock holder plate 2 are arranged.
- the lock case 5 is usually made as a stamped sheet metal part and carries the locking mechanism consisting of a rotary latch 4 and pawl 17.
- the locking mechanism 18 consisting of a rotary latch 4 and pawl 17 and the lock casing 5 are parts of the motor vehicle door lock.
- the lock holder 1 is usually attached to the body of the motor vehicle, with the motor vehicle lock being arranged in the movable component of the motor vehicle.
- FIG. 3 shows the view of the lock holder 1 according to the invention from the direction of arrow III.
- the locking mechanism 18 is shown in a main locking position, that is to say the rotary latch 4 is locked in the closed position by means of the pawl 17, which is an exemplary full corresponds to a constantly closed door or tailgate.
- Rotary latch 4 and pawl 17 can each be pivoted about their axes 6, 20, so that a latching position, that is to say a pre-latching position and a main latching position, can be occupied.
- the projection 8 protrudes beyond the tentacle 13, so that in the event of an increased load and a corresponding deformation of the motor vehicle, the projection 8 and the middle piece 9 are in contact with the reach the rotary trap. This can result in a significant increase in load.
