Definitions
- the invention relates to a lock holder for a motor vehicle door lock, having a lock holder plate and a lock holder bracket attached to the lock holder plate, the lock holder bracket being designed with a locking bolt, a center piece and a connecting bolt.
- the lock holder usually interacts with a locking mechanism of an associated motor vehicle door lock.
- Lock holder and automobile door lock generally define the automobile 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.
- the lock holder 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, especially in the event of an accident. In fact, the protection of vehicle occupants in the event of a side impact depends largely on how reliably the lock holder and the interacting mechanism 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 forces in the motor vehicle door lock included locking mechanism 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 catch and a main catch, which can be present in the door lock depending on the door element.
- the respective locking position i.e. main locking or pre-locking
- 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. For a positive connection, the part of the lock holder bracket or the locking bolt and/or the connecting bolt that protrudes beyond the lock holder plate is compressed.
- the lock holder plate is also equipped with a bulge, which ensures that compression caps created as a result of the compression process on the underside of the lock holder plate 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.
- a lock holder for a motor vehicle door lock having a lock holder plate and a lock holder bracket attached to the lock holder plate, the lock holder bracket being designed with a locking bolt, a center piece and a connecting bolt, and wherein the Lock holder bracket is designed at least in two parts.
- the design of the lock holder according to the invention now creates the possibility of making the lock holder bracket 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 a secure locking of the door can the other safety systems, such as brake assistant, seat belt and airbags, be fully effective.
- the loads in 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 is. This is where the invention comes into play in particular and shows a way to improve the resilience of the lock holder.
- 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, foldable bench seats, etc., wherever it can be pivoted or moved on the motor vehicle Components used 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 fastening 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 is preferably divided into three areas that include different functions.
- the lock holder bracket has a center piece and a connecting bolt.
- the locking bolt is the part of the lock holder bracket that engages with the locking mechanism and in particular the rotary latch.
- the rotary latch comes into engagement with a locking bolt attached to the motor vehicle and is rotated by means of the interaction and a relative movement between the locking bolt and the rotary latch, so that the rotary latch can reach its locking position.
- 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.
- a middle piece extends essentially parallel to the lock holder plate, whereby an engagement area for the rotary latch in the locking 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.
- a lock holder bracket designed according to the invention offers the possibility of individually reinforcing the locking bolt, since the locking bolt can be designed as a separate component to suit the requirements and in particular the loads in the event of an accident.
- the lock holder bracket can be formed from a first part forming the locking bolt and a second part forming the middle piece and the connecting bolt.
- the locking bolt forms a separate component which interacts directly with the locking mechanism and which can be designed to be adaptable to the interaction with the rotary latch.
- the interaction or interaction of the rotary latch and the locking bolt is of essential importance in the load capacity of the lock holder, since the force in the event of an accident as well as during a tensile test is transmitted via the locking bolt to the rotary latch or the locking mechanism, or vice versa.
- the locking bolt has a substantially cylindrical shape and is preferably designed as a lock holder bolt.
- a cylindrical basic shape of the locking bolt enables easy interaction between the rotary latch and the locking bolt.
- the rotary latch has an inlet mouth in the usual design, the inlet mouth being formed by a catch arm and a load arm. Catch arm because when the rotary latch first engages with the locking bolt, the catch arm comes into engagement with the locking bolt, after which, when the rotary latch is closed or the rotary latch is closed in the main grate, the load arm interacts with the locking bolt in such a way that the tensile force or In the event of a crash, the holding force is transmitted.
- the load arm as well as the catch arm are designed as stamped parts that can have a plastic coating, but which have flat surfaces that interact with the locking bolt. This means that the cylindrical shape of the locking bolt, which at least in one If there is a grip area for the rotary latch, easy intervention, twisting and holding of the locking system can be achieved.
- the middle piece has a flattened area and the flattened area can be connected to the locking bolt.
- the locking bolt is therefore permanently connected to the lock holder plate on one side and to the center piece on the opposite side by means of forming.
- the lock holder bracket has at least one material compaction, the load capacity can be increased and thus safety in the motor vehicle can be increased.
- the lock holder bracket i.e. the locking bolt, the center piece and the connecting bolt, are connected to the lock holder plate as a bracket. Thickening the lock holder bracket in the area of the lock holder plate makes it possible to increase the load capacity of the lock holder bracket. Due to the thickening in the base area of the locking bolt and, if necessary, the connecting piece, the contact surface on the fastening plate or the lock holder plate can be maximized. By maximizing the contact surface, the resistance to bending stress is increased. A bending stress can act on the locking bolt in particular in the longitudinal direction of the vehicle or in the vertical direction.
- 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 be increased in particular in the y and z directions.
- the locking bolt can have a material thickening in the connection area to the center piece.
- the thickening of the material can increase the contact surface between the locking bolt and the center piece, in particular the flattened area of the center piece, so that the bending strength can be increased.
- the thickening of the material in the area of the middle piece increases the bending strength.
- the material thickening can advantageously increase a contact surface when riveting the locking bolt, so that an additional contact surface is available for riveting or forming.
- the material thickening on the locking bolt in the connection area to the center piece forms a contact surface for the rotary latch.
- the design of the locking bolt according to the invention which additionally provides a contact surface for the rotary latch, allows the load capacity of the lock holder bracket to be significantly increased.
- the installation of the rotary latch results in a load distribution from the locking bolt to the rotary latch. Because the rotary latch is not only in engagement with the locking bolt through the load arm, but according to the invention via the collar formed by the thickening, that is to say that the rotary latch is in contact with the locking bolt at least in some areas, the force can be transmitted from the load arm to the catch arm .
- the load arm of the rotary latch is relieved and the tensile strength in the x direction, i.e. in the lateral direction of the motor vehicle, is improved.
- the crash collar designed according to the invention can be used to transfer the contact surface between the rotary latch and the locking bolt to a lateral force transmission between the rotary latch and the locking bolt.
- the rotary latch also lies on the side of the crash collar, i.e. the thickening, which in particular increases the tear resistance.
- the crash collar or the thickening can be designed as a flat contact surface on the locking bolt. It can also be advantageous if the middle piece and the connecting bolt are made in one piece and made of one wire.
- the one-piece design of the center piece and connecting bolt offers the possibility of producing the lock holder bracket cost-effectively and at the same time precisely.
- the two-part nature of the lock holder bracket allows an individual adaptation to the engagement conditions between the rotary latch and the lock holder bracket.
- the lock holder bracket can therefore be individually reinforced in the area of interaction between the locking bolt and the rotary latch and can additionally improve the force transmission between the rotary latch and the lock holder bracket.
- the center piece and the connecting bolt can have a different geometric cross-sectional shape. If it is advantageous in the area of the connecting bolt if the connecting bolt has a circular cross-sectional shape, it can be advantageous in the area of the center piece if the center piece has a cross-sectional shape that can be described essentially as a rectangular shape.
- the design of the cross-sectional shape allows the lock holder bracket to be individually adjusted to the loads occurring in the lock holder bracket. But the space conditions in the interaction between the lock holder bracket and the motor vehicle lock can also play a role in the design of the cross-sectional shape of the center piece and connecting bolt, since the space conditions in the motor vehicle lock are usually reduced.
- a flat shape of the center piece can therefore advantageously influence the installation space in the motor vehicle lock, since a flat design of the center piece requires less space in the interaction between the motor vehicle lock and the center piece.
- the individual structure of the lock holder bracket allows an adaptation to the interaction between the rotary latch and the locking bolt, which in turn can increase the load capacity in the event of an accident.
- the individual design of the lock holder bracket allows the load to be distributed and the tensile strength of the lock holder bracket can also be increased.
- Figure 1 is a three-dimensional view of a lock holder designed according to the invention, with a plastic support, lock holder plate and lock holder bracket,
