Definitions

  • the invention relates to a motor vehicle door lock, with received in a housing locking mechanism, and with a reinforcing element for the locking mechanism.
  • the ratchet is usually composed of a catch and a pawl and cooperates with a locking pin, as is well known and, for example, in the generic state of the art according to the DE 199 34 877 A1 is described.
  • a reinforcing element in the form of a quasi-closed housing for receiving the locking realized.
  • reinforcement elements from practice in the form of reinforcing plates, which are connected to the housing by riveting.
  • case may be a lock case or a lock plate, which is made of metal and in which the locking mechanism is stored.
  • the reinforcing element is now riveted to the relevant lock case or lock plate - as described. This is expensive to manufacture.
  • the locking mechanism is exposed to increased forces, in particular in the event of a side impact, for example if an outer door panel is pressed against the housing or the lock case or the lock plate and possibly causes deformations here. That can be extreme lead to a blockage of the locking mechanism, so that an associated motor vehicle door is no longer open.
  • a motor vehicle door lock is known with a received in a housing locking mechanism and with a reinforcing member, wherein the housing has a fastening web, which protrudes in a receptacle of the reinforcing element.
  • the reinforcing element absorbs forces acting on the housing without torque with respect to the locking mechanism.
  • the known embodiments allow for improvements in crash safety.
  • the invention is based on the technical problem of further developing a motor vehicle door lock of the design described at the beginning in such a way that the crash safety is improved, in particular in the case of a side impact, and an associated locking mechanism can (still) be opened without difficulty.
  • a generic motor vehicle door closure is characterized in that two fastening webs and two axes of the locking mechanism are realized, by means of which the reinforcing element is held on the housing, wherein the fastening webs and the axes of the locking mechanism form a trapezoid.
  • forces associated with a side impact for example, still lead to deformations of the door outer panel, which can propagate to the housing of the motor vehicle door closure.
  • the special support of the reinforcing element ensures that such deformations do not result in the forces exerted on the locking torque.
  • the aggregate of reinforcing element, housing and locking mechanism thus absorbs such forces torque-free with respect to the locking mechanism.
  • the housing has two fastening webs for the reinforcing element, which project into a receptacle of the reinforcing element.
  • the connection between the reinforcing element and the housing can be made in the usual manner, for example by gluing, but also latching, by means of a plug-in connection, etc.
  • an interference fit between the fastening web and an associated receptacle in the reinforcing element is especially proven at this point.
  • two fastening webs are realized, which form a trapezoid in conjunction with two axes of the locking mechanism. That is, the connecting lines between the two fastening webs and the two axes of the locking device are largely parallel to each other.
  • the fastening webs may be arranged symmetrically in comparison to a possible impact force direction or impact direction. The impact force direction thus defines a mirror axis for the two fastening webs.
  • the reinforcing element is usually arranged coplanar compared to a base plate of the housing and may be formed as a reinforcing plate.
  • the reinforcing element or plate - as the aforementioned base plate of the housing - extends substantially in the YZ plane, wherein the mirror axis coincides largely with the Y direction and consequently also the side impact force direction.
  • the press fit between the housing and the reinforcing element engages in detail on wedge-shaped or cam-shaped fastening webs, which run upwards on a fold of the housing upwards.
  • the reinforcing element or the reinforcing plate is arranged approximately in the center in comparison to an inlet mouth or the locking pin in its closed position, in order to achieve a particularly effective support of the axes of the locking mechanism and to promote the force application described in a side impact.
  • a motor vehicle door lock is provided, which is convinced that the function of the locking mechanism is practically not disturbed, in particular in a side impact.
  • This provides essentially the reinforcing element or the reinforcing plate, whose special arrangement of holding them axes of the locking mechanism in conjunction with the fastening webs and the record ensures that even in a side impact, the reinforcing element or the reinforcing plate is not rotated about one of the axes of the locking mechanism is, therefore, such Forces are absorbed torque-free with respect to the ratchet of the reinforcing element.
  • a motor vehicle door lock is shown, which in its basic structure via a housing has, which is presently designed as a lock case 1 or such a lock case 1 includes.
  • a lock case 1 in cross-section U-shaped with side walls 1b and 1c is designed.
  • a locking mechanism 2, 3 from catch 2 and pawl 3 is added.
  • bearing pins 4 are anchored in a base plate 1a of the lock case 1 and receive the catch 2 and pawl 3 respectively.
  • a reinforcing element 5 is realized, which is a reinforcing plate 5.
  • the reinforcing plate 5 and the base plate 1a of the lock case 1 are arranged substantially coplanar with each other, ie span mostly parallel planes. Between these two levels or the reinforcing plate 5 and the base plate 1a, the rotary latch 2 and the pawl 3 are held.
  • the reinforcing plate 5 is fixed by means of press-fits 6 on the housing or lock case 1. Details of the respective press fit 6 are best recognized by the enlarged detail in FIG Fig. 3 , Thereafter, the reinforcing plate 5 has recesses 7, through which fastening webs 8 reach through.
  • the fastening webs 8 are formed on the lock case 1 and protrude from its side wall 1b. Spring tongues 9 in the region of the recesses 7 engage with the reinforcing plate 5 positioned on the fastening webs 8.
  • the fastening webs 8 are wedge-shaped or cam-like and run starting from the bottom of the side wall 1 b towards the top as it were conical.
  • the spring tongues 9 in the region of the recesses 7 strike a growing cross section of the respective fastening web 8, so that the described press fit 6 is achieved, as shown in the enlarged illustration Fig. 3 immediately makes it clear.
  • the spring tongues 9 are bent up as a result of the wedge shape of the fastening webs 8 and increasingly hold the reinforcing element or reinforcing plate 5 on the lock case 1.
  • the respective nearly rectangular recess 7 is equipped with a total of three spring tongues 9 on three sides of the rectangle.
  • this larger spring tongue 9 one finds a corresponding bevel of the respective attachment web 8, so that the respective spring tongue 9 is increasingly bent upwards when the reinforcing element 5 is pressed onto the side wall 1 b of the lock case 1.
  • the reinforcing element or the reinforcing plate 5 has a lateral projection 11, which is particularly in the Fig. 2 recognizes.
  • This projection 11 is laterally above the housing 1 or the lock case 1 via, namely by the amount M, as the side view Fig. 3 immediately makes it clear. It extends substantially in the opposite direction compared to a possible impact direction which is indicated by an arrow A in the figures.
  • the impact direction A extends for the most part in the Y or vehicle transverse direction, assuming a side impact.
  • a rear impact must also be taken into consideration, which is generally congruent with the X or vehicle longitudinal direction.
  • the reinforcing element or the reinforcing plate 5 is designed substantially plane and arcuate and has a recess 12 in the region of an inlet mouth 13 for a merely indicated and cooperating with the catch 2 locking bolt 14.
  • a back 15 is provided, which in general with the supernatant 11 coincides.
  • two fastening legs 16 for the axles 4 of the rotary latch 2 of the pawl 3 complete the reinforcing element 5.
  • the reinforcing element or the reinforcing plate 5 additionally has a receptacle 17 in the form of a receiving bore 17 for a lever 18.
  • This lever 18 is the external actuating lever 18, which is actuated by a merely indicated outside door handle 19 with the interposition of a connecting member 20, for example a rod or a Bowden cable.
  • the axes 4 of the catch 2 and pawl 3 like with the reinforcing element 5 riveted.
  • This may also apply to a bearing pin or an axis 21 on the outer actuating lever 18, wherein the outer actuating lever 18 and bearing pin or axis 21 can form a one-piece unit.
  • the reinforcing element 5 or the reinforcing plate 5 is arranged substantially centrally in comparison to the inlet mouth 13. That is, when the catch 2 is closed, the locking bolt 14 is mostly in the center of the recess 12 of the reinforcing plate 5.
  • the reinforcing element or the reinforcing plate 5 absorbs forces acting on the housing 1 or the lock case 1 without torque in relation to the locking mechanism 2, 3.
  • these forces are lateral forces in the Y direction, as the force arrow or the direction of impact A running in this direction makes clear.
  • the trapezoidal shape is adjusted because the two fastening webs 8 and the two axes 4 are connected to each other by parallel connecting lines. It can be seen that the impact force direction or impact direction A forms a mirror axis for the two fastening webs 8. On this mirror axis of the locking pin 14 is in the illustrated closed state of the motor vehicle door lock.
  • the opposing forces built up by the two axes 4 of the locking mechanism 2, 3 are indicated by arrows which intersect at a point on the respective mirror axis or the impact direction A.
  • forces in this impact direction A or impact force direction A are received symmetrically by the reinforcing element 5 and no torques are exerted on the axles 4 of the locking mechanism 2, 3.
  • the two axles 4 of the locking mechanism 2, 3 do not undergo any deformations, so that the locking mechanism 2, 3 basically functions in such a case as well.
