Definitions
- the invention relates to a lock for a motor vehicle having the features of the preamble of claim 1.
- a lock for a motor vehicle comprises a locking mechanism with a rotatably mounted rotary catch for receiving a locking bolt, which is also suitable for locking.
- the locking mechanism further has a pawl with which the catch can be latched for holding the locking bolt.
- the catch of a Kraftfa vehicle lock usually has a ngarm by load arm and Fa fork-shaped Einlaufsch litz (also called inlet mouth) in the locking bolt of a vehicle door or Kla ppe, such as hood or Kofferraumkla ppe, passes when the door or flap is closed.
- the locking pin or Schlossha age then rotates the catch from an open position towards the closed position until the pawl the Drehf all locked. This position is called detent position.
- the locking pin can not leave the inlet slot of Drehfal le then.
- the pre-detent position serves to intercept the corresponding door or flap if it does not reach the main detent position when closing. If the catch, starting from the pre-latching position, is turned further, the latch finally reaches the home-latching position. In case of a power failure, u. a. for the sake of user-friendliness sought to be able to open this with little force.
- the force to be used for opening depends, among other things, on a balance between the two Fulcrum of the catch and H auptrast (first lever) and between the pivot point of the catch and Konta kt Scheme or Konta ktddling between the locking pin and the load arm (second lever) from.
- the first lever starts at the center of the catch and opens vertically in the direction of the force, entlteil the press arm of the catch in the Hau ptrastposition presses against the pawl.
- the second lever starts at the center point of the rotary traps. If the locking mechanism is in the main locking position, then the locking bolt exerts a force whose direction encloses a right angle with the second lever, as illustrated by FIG. 1 of DE 1 0 2009 029 01 6 AI.
- the second lever ends at the height of this force arrow.
- the Constant between the first lever and the second lever is called blocking part ratio.
- the DE 1 0 2009 029 01 6 A I Figure 1 discloses a mounted on a plate made of metal plate of a lock case locking in which the locking part ratio is 3.
- the load arm of the rotary latch is significantly wider than its handle arm.
- the tentacle tapers towards its open end, as this end is the least affected. This saves material and weight.
- the load arm becomes thicker toward its open end in order to be able to arrange both a latching surface for the pre-latching position and a latching surface for the high-load latching position on the load arm.
- the pawl of the locking mechanism is arranged adjacent to a side lock box wall, so that the Sperrklin ke can be supported against this lock case wall kan n, if this should be exposed to a strong force in the event of a crash.
- the inner end or the inner end of the inlet mouth means from the said contact area or contact point between the locking pin and the load arm from the end, which lies at the bottom of the rotary latch inlet slot.
- a lock with a locking u comprehensive a catch provided with a m Lastarm and a tentacle, which is rotatably mounted on a rotary latch axis and a lock pin can take men according to claim 1.
- the rotary latch axis Seen from the side with the outer end of the inlet mouth along the second lever, the rotary latch axis is displaced laterally in accordance with the prior art known from the documents DE 1 0 2007 585 A1 and DE 1 0 201 0 036 924 A1 arranged next to the inner end of the inlet mouth.
- there are areas of the rotary catch axis and the inner end of the intake mouth which are arranged side by side.
- a portion of the rotary latch axis which is arranged in front of the inner end of the inlet mouth. In this latter embodiment, the axis of the catch reaches into the tentacle area.
- the length of the second lever almost arbitrarily small to di mensions, without jeopardizing the mechanical stability. It can be so cheap locking part ratios, for example, achieve at least 4, oh ne for it to provide an excessively large space for the locking mechanism. Unproblematic it is possible to provide a blocking division ratio of five and more so as to unlock the locking mechanism with little force.
- the center of the rotary latch axis in the aforementioned sense is behind the inner end of the inlet mouth of the rotary latch or at the level of the inner end. It is thus ensured that the length of the second lever is suitably different from zero in order to be able to rotate the catch in the opening direction with the aid of the striker.
- the axis of the pawl is preferably made of metal for stability reasons. However, this can be made with a smaller diameter than usual. As a result, material and space is saved.
- the pawl made of plastic advantageously the weight and the manufacturing cost is reduced.
- a production of plastic has an advantageous effect on a noise, since it is reduced and in particular a so-called ⁇ Stammsplopp.
- an optionally provided biased spring for the pawl may be made weaker, which advantageously reduces mechanical stress.
- An optionally provided prestressed spring for the pawl is able to move the pawl into its detent position, in particular.
- the inlet mouth extends in sections arcuately around the rotary latch axis and in particular the portion which comprises the inner end of the inlet mouth.
- the axis of rotation of the pawl can thereby sufficiently removed from the central axis of the lock holder and the lock pin to be ordered.
- This embodiment further enables a mechanically stable, yet small design of the rotary latch. It is also possible to pivot the catch by less than 90 ° in order to move from its open position to the main catch position and vice versa. Small swivel movements are advantageous, among others, to open and close quickly and quietly with low energy consumption and to keep the space small.
- a guide according to the present invention means a parallel course of two opposing boundaries, so the corresponding opposite side contours of load arm and tentacle.
- the width of a guide is only slightly larger than the diameter of a locking bolt in order to achieve noise advantages and to be able to keep the installation space small.
- the portion of the lead-in mouth that includes the outer end of the lead-in mouth is arc-shaped, and vice versa, arcuate in comparison to the portion provided in one embodiment that extends arcuately about the rotary-disc axis.
- This embodiment further enables a mechanically stable, yet small design of the rotary latch. Further is improved allows the catch to less than 90 ° strigwen ken to get from its open position to the main detent position and vice versa.
- the lock is installed in such a way in particular in a door, that in the H auptrastposition the inner end of the inlet mouth is located m u nterrenz the upper end of the enema.
- the pawl can rust for rusting the catch a m Lastarm or a m Fangarm.
- the outer end of the inlet mouth of the rotary latch can lie in the installed state above the inside end or, for example, below it. In particular, this alignment is tailored to the available construction space.
- the blocking part ratio of the object according to the invention is preferably above three, more preferably above five. It has been found that with the present invention in particular blocking sub-ratios of 5.5 to 6.5 can be implemented in a practical manner. Barrier ratios of up to 7 are usually possible. Blocking ratios of more than 7 can indeed be realized, but in principle result in undesirably large construction space enlargements.
- the lock holder is preferably held by a clamp.
- FIG. 1 shows ratchets in the main ratchet position.
- the rotary latch 1 shows a rotary latch 1 which is locked by a pawl 2.
- the rotary latch comprises a catching arm 3 and a load arm 4, by means of which an inlet slot 5 is formed.
- a running slot 5 holds a lock holder or locking pin 6.
- the lock holder 6 is pulled with a force F in the direction of the arrow shown.
- the load arm 4 prevents the lock holder 6 from being moved out of the ratchet by the force F.
- the rotary latch 1 is rotatably supported by an axle 7.
- This axis 7 of the catch 1 extends partially into the region of the tentacle 3 and is therefore partially adjacent or in front of the inner end 8 of the Einlaufma uls 5 and seen along a direction of the force arrow F sen direction and from the outer end 9 of the inlet mouth. 5 seen from.
- the orientation shown in FIG. 1 of the rotary latch 1 corresponds to the state installed in a door, so that the outer end 9 of the inlet sleeve 5 lies above the inner end 8.
- the Sperrklin ke 2 is rotated around its axis 1 1 clockwise around, so she leaves her detent position.
- the catch 1 can then be rotated or pivoted in the clockwise direction n in the direction of opening. If the catch 1 has reached its opening position, the lock holder 6 can leave the locking mechanism.
- the stop 1 0 also limits this pivoting or rotational movement of the rotary latch 1 in the clockwise direction n, that is, a rotation for opening the locking mechanism.
- the distance between the axis 7 to neren end 8 is similar to the Absta nd the rotary latch axis 7 to the left shown n edge of the rotary latch or the tentacle 3.
- the axis 7 is thus at least approximately centrally between the inner end 8 of the egg jaw mouth 5 and the opposite, outer edge of the tentacle angeord net. This ensures the mechanical stability and load capacity of the tentacle with optimized material usage.
- the Fa ngarm 3 is as shown at the level of the inner end, in the rotary latch axis. 7
- the tentacle is in this area 1, 5 to 2.5 times as wide as the load arm 4.
- outer end 9 of the inlet mouth 5 tentacle and load arm are like shown advantageous aft ä similar wide to minimize the use of materials and thus weight and space.
- the width of the tentacle 3 here corresponds to the width of the load arm. 4
- the first lever extends in accordance with the illustrated distance 5a, so that the locking mechanism shown in FIG. 1 has a locking part ratio of 5.
- the inlet mouth 5 extends from the inner end 8 initially arcuately around the rotary latch axis 7 around and in about half of the Gesa mtuza of the inlet mouth 5.
- the adjoining portion of the inlet mouth runs umgeke hrt arcuate to approximately the outer end. 9 the inlet mouth.
- This course contributes to optimized material use, with which the mechanical stability can be achieved.
- arcuate courses which are formed by parallel lateral boundaries or contours of load arm 4 and Fa ngarm 3, d the locking pin 6 is guided over more than 5 mm. Such guidance can provide appreciable noise benefits.
