Description

DESCRIPTION

Lock for a vehicle door with spring plate in the inlet area of the locking bolt

The invention relates to a lock for a door or flap of a motor vehicle or building, which has a lock housing and a catch having a catch and a pawl locking mechanism, wherein the

Rotary latch is pivotally mounted about an axis and cooperates with a body associated with the closing bar when opening and closing the door. Motor vehicle locks, but also other locks with striker and

Rotary latch are basically known, wherein the striker are often shaped wires that are fixed to a base plate. at

Motor vehicle locks in the automotive industry is usually a locking mechanism of the catch and pawl used to attach the body side

Lock the striker or fix the door. The

Kraftfahrzeugschioss is usually attached to the vehicle door or a tailgate. In the closed state of such a lock, the catch often engages with its load arm around the locking pin of the striker. The catch also pulls the locking bolt against the force of the door seal in the Kraftfahrzeugschioss and is then blocked even by means of the pawl so that accidental opening is excluded. When driving the motor vehicle, however, movements occur between the rotary latch and the locking bolt. In particular, it is possible that

Relative movements between the catch and the latch bolt lead to compressive stresses and / or frictional forces, so it just when the onset of

Dust grains to the so-called creaking, d. H. to corresponding

Noise may come. For safe operation of a lock and for influencing the said noise describes the DE 20 2006 018

CONFIRMATION COPY 744 U1 a damper element or a damper, which is arranged with the door or flap closed directly adjacent to the rotary latch and designed yielding to cushion the inserted over the lock inlet area locking bolt. This damper element has a guide portion which forms at least a portion of the receptacle in the direction of the opening region of the lock inlet region. From WO 2007/073723 A1 is a

Motor vehicle door lock with a catch of rotary latch and pawl and a damper element known. The round executed there

Damper element limited in conjunction with associated Gesperreanschlägen both an opening and a closing movement of the rotary latch. This damper element consists of an elastomeric plastic.

The present invention is based on the object

To further reduce noise developments between the catch and the locking pin and to prevent as completely as possible, in particular to avoid a so-called creaking in the region of the lock connection to the body.

The object is achieved according to the invention in that in the lock inlet region of the lock housing an at least substantially parallel to the rotary latch oriented spring plate is arranged, which is the

Includes striker in the closed position of the lock.

This spring plate, in addition to the measures provided for in the prior art damper elements possible movements of the

corresponding door or flap intercepted perpendicular to the direction of travel of a vehicle, with a vehicle side door thus such movements or vibrations that take place around the corresponding hinge points of the door around. The spring plate used according to the invention does not have the high temperature dependence of the otherwise used rubber or plastic buffers. Optionally, the usual use of the above-described, in addition to the catch arranged damper according to DE DE 20 2006 018 744 U1 and possibly also to the there also described Inlet lip are omitted. For the production of the entire lock housing lower tool costs and you have in the choice of materials more options, especially since the previously common spring lip is eliminated. It is advantageous, finally, that the lack of additional openings, for example, for the rubber buffer in the lock housing, the necessary water management is lower.

According to an advantageous embodiment of the invention it is provided that the spring plate is designed as a spring steel existing spring clip. Such a spring clip can be designed so that the unavoidable movements of the motor vehicle door are damped during driving. The spring plate used thus restricts the movements of the lock housing and thus the door in the Z direction, ie in the direction perpendicular to the direction of travel of a vehicle in this case so that thus the door is additionally quiet. The said additional or

Creaking noises are less or completely eliminated.

According to a further expedient embodiment it is provided that the striker has a locking bolt, a support bolt and a transverse bolt arranged between them, wherein the catch comprises the locking bolt when opening and closing the lock and the spring plate the cross bolt in the closed position of the castle. When closing the door of the locking pin is inserted into the spring clip, which then surrounds the upper end portion of the locking bolt and in particular to the cross bolt and this securely detected, so as to secure the immobilization of the door. Because the spring plate engages the striker in the region of the transverse bolt and the catch engages the striker in the area of the striker, both components act to dampen the striker, at a distance from each other and in other directions, which has an advantageous effect.

An expedient embodiment of the spring plate provides that the spring plate has two outgoing from a round arch spring arms, the Fixing in the lock housing with their free ends are bent away from the cross bar. In this way, the spring plate acts targeted and under

Increase the pressure forces in the area of the bends on the cross bolt of the striker, so that when driving the vehicle by movements of the door or flap resulting noise are attenuated accordingly. The cross bolt is between the two spring arms after reaching the

Closed position of the castle arranged so that the pressure forces are advantageous in the Z direction, that is perpendicular to the direction of travel of the vehicle.

According to a development it is provided that the spring arms

Have bends with which the spring arms linearly shaped and formed the application and concerns on the cross bolt or formed. Thus, the two spring arms can act in the optimum range on the cross bolt this fixing and take effect together with the catch, so that the door or flap is so quiet as desired.

For easy assembly of the lock housing in particular but in particular of the spring plate is provided that the lock housing has the spring plate with the round arch and the spring arms receiving internals. In this case, no holes or omissions are provided in the lock housing, which, as already mentioned, facilitates the water management, but in particular the spring plate or the spring clip can be easily inserted into the lock housing, then equal to take the correct position without additional welding o. Ä.

This insertion is facilitated in particular by the fact that the

Built-in the bias voltage are designed according to arcuately extending and so the insertion or insertion of the

Enable spring plates. Due to the spring action of the spring plate no separate setting in the fittings is necessary, but rather fits the entire spring clip in the circumstances of the lock housing advantageous safe.

An overload of the spring arms or an unintentional

Deformation is precluded by the fact that the internals are designed and arranged to limit the movements of the free ends of the spring arms. This means that in particular the free ends of the spring arms are not only fixed by the spring action in the internals, but also by the internals limited movements on the cross bolt out or can run away from it.

The resilient action of the spring plate can also be adjusted in addition to the choice of material that the spring plate preferably over the entire length at least with the diameter of the transverse pin

is designed correspondingly wide or a round arch with a Reduziersprung.

The invention is characterized in particular by the fact that a component is made available by the spring plate, which ensures without much additional manufacturing and setup costs that the noise during operation of the vehicle are largely or even completely avoided. The door is controlled both by the catch itself and in particular by the

Spring plate held steady. Even if dust or even sand in the

Lock housing should get in, is prevented by the selected design in particular of the castle, the emergence of creaky noises. A further advantage is that for the assembly of the spring plate, the lock housing does not need to be pierced or otherwise influenced, but that the spring plate simply provided in internals or attachments of the

Lock housing is inserted.

Further details and advantages of the subject invention will become apparent from the following description of the accompanying drawings, in which preferred embodiment is shown with the necessary details and items. Show it:

Figure 2 is a plan view of a lock housing, here without a catch, Figure 3 shows a longitudinal section through the lock housing with

Locking bolt and spring plate,

FIG. 4 shows a cross section through the lock housing with locking bolt and spring plate,

Figure 5 is a plan view of the castle inlet area with the

inserted spring plate and

Figure 6 is a perspective view and illustration of the

Positions of rotary latch and spring plate in relation to the striker.

FIG. 1 shows a part of a lock 1 provided for motor vehicles with the lock housing 3 assigned to the door 2 and the striker 9 associated with the body 8. In the lock housing 3, the catch 4 is housed and also further associated, but not shown here components of the locking mechanism and the fuse, for. B. the pawl. The rotary latch 4 is shown in the closed state of the lock 1, wherein the rotary latch 4 has pivoted or rotated about the inserted over the lock inlet region 5 striker 9 and its locking pin 10. This is recognizable

Spring plate 15, which here has a certain distance from the locking pin 10, as well as the axis of rotation 22 around which the rotary latch 4 is rotated. Due to the special shape of the rotary latch 4, the door 2 pulls during the closing process in the direction of the body 8, so that it comes to closing the door 2. The closure also takes place against the force of not shown here

Door seals. When tightening the door 2, the rotary latch 4 sets tightly against the locking pin 10 of the striker 9, which Figure 1 makes clear. These Movement of the door 2 takes place in the Y direction, that is to say almost horizontally

Direction of travel in the direction of the motor vehicle seats.

In Figure 2, the rotary latch 4 is not mounted with and therefore not visible. As a result, the shape or position of the striker 9 is clearly visible. With 10 is the locking pin and with 1 1 the opposite

Designates support bolts, which are connected to each other via the cross bolt 12.

The spring plate 15 is formed as a clip 16 and spring clip, wherein the round arch 17 is responsible for the necessary contact pressure on the cross bolt 12 with. At this round bow 17 close two spring arms 18, 19, whose free ends 20, 20 'are slightly bent or folded. The two spring arms 18, 1 9 are as indicated in Figure 2 exactly in the area of

Turning 24 on the striker 9 or especially on the striker 12 at. Further details are shown later.

Figure 3 shows a longitudinal section through the lock housing 3, wherein it can be seen that the Bolzenfuß 23 of the locking bolt 10 has a shape that makes a secure anchoring in the base plate not shown possible. The locking bolt 10 itself is in some way in the

Lock housing 3 retracted and is included in the region of the transverse pin 12 of the dashed lines reproduced here spring plate 15. Visible is next to the striker 9 and locking pin 10 and the catch 4 with her

Axis 22. Due to the selected section here the inner sides of the rotary latch 4 are reproduced at a certain distance from the locking pin 10.

The spring plate 15 is in designated internals 26 ins

Lock housing 3 is used, the particular shape of the spring plate 15 is particularly highlighted by Figure 5 again. In this case, in addition to the Z direction 37 and the direction of travel 35, ie the X direction indicated, which makes it additionally clear that the retraction of the striker 9 in the Lock housing 3 and the lock inlet area 5 at right angles, to

Driving direction but horizontally.

Notwithstanding Figure 3, a cross-section is shown in Figure 4, which is also recognizable that the entire striker 9 actually only the locking pin 10 and just here also the cross pin 12 are influenced by the spring plate 15 to the best possible fixation of the locking pin 10 in the catch 4 and in the spring plate 15 to secure. It can be seen that the rotary latch 4 in the region of the bolt foot 23 comprises the locking bolt 10, while the sphere of influence of the spring hinge 15 at a distance from it lies in the interior of the lock housing 3 in the region of the transverse bolt 12 and the upper end of the locking bolt 10. In addition, it can be seen in FIG. 4 that the spring plate 15 has a so-called reduction jump 27, ie. H. the width of the spring plate 15 is in the region of the transverse pin 12 and thus the

Spring arms 18, 19 larger than in the region of the round arch 17 and des

Lock bolt 10. The correspondingly larger width in the area of

Transverse pin 12 allows in particular an effective pressing against the cross bolt 12 and thus to the striker 9, while in the round bow 17, the spring plate 15 is correspondingly narrower. Thus, the spring force can be influenced by the said reduction jump 27 is selected adjusted accordingly. It can also be seen in FIG. 4 that the spring plate 15 can be arranged securely inside the lock housing 3 via internals 26, wherein advantageously the preformed component spring plate 1 5 can simply be pushed into the recesses or installations 26 from above. The direction of travel or X direction is denoted by 35 and the Y direction by 36, that is to say the Y direction. H. that is, the horizontal direction to the direction of travel, in which the striker 9 is moved into the sphere of influence of the lock housing 3 and in which the seats extend.

The lock inlet area 5 is clearly visible in FIG. 5, this lock inlet area 5 extending in a funnel shape. Visible is also the

Storage of the free ends 20, 20 'of the spring arms 18, 19 in the Einbauten26 of Lock housing 3. It is also recognizable that adjoins this spring arms 18, 19 of the circular arc 17, the two spring arm 18, 19 connects to each other. It is further clarified that the spring arms 18, 19 in particular in the area of the bends 24 create a tight line on the transverse bolt 12 and thus on the 5 striker 9, so that here the desired additional fixation to the catch 4 is always safely realized. It can be seen in this figure further that the range of motion of the spring arms 18, 19 and their free ends 20, 20 'is limited by the correspondingly shaped internals 26, so that a

Overloading of the spring plate 15 is excluded. FIG. 5 further shows that

10, the entire spring plate 15 can be inserted from above into the corresponding fittings 26. If necessary, it is possible that on the inside of the spring plate 15 elastic plastic material 29 is applied to catch and bump off any shocks during insertion of the locking pin 10 into the lock housing 3 easy. Again, the Z direction is 37,

15 transverse to the direction of travel, and the Y-direction 36 indicated.

Finally, FIG. 6 shows the parts of the lock 1 which are important here in a perspective representation and the assignment of these components to one another.

Recognizable is the striker 9 with the locking pin 10 and the support bolt

While the rotary latch 4 is pivoted or rotated about the locking pin 10 when closing the lock 1 so as to move the door 2 in the direction of the body 8, the spring plate 15 in the form of the bracket 16 in the direction 36, ie in the Y direction, pushed onto the striker 9 and in particular on its transverse pin 12,

25 wherein also the locking pin 10 is enclosed with. This spring plate 15 now presses in the position shown with the spring arms 18, 19 and in particular in the area of the bend 24 on the cross pin 12 and in the Z direction 37, thereby framing the cross pin 12 and thus the door 2 advantageously additionally quiet can be. 35 shows the X direction, ie the

30 direction of travel, while Y and 36, the insertion direction, with which the spring plate 15 aufschiebt on the cross bolt 12. All mentioned features, including the drawings to be taken alone, are considered to be essential to the invention alone and in combination.
