EP2138656A2 - External door handle, in particular for vehicles - Google Patents

Abstract

The handle has a manually operatable handle part (10) acting on a lock provided in a door during actuation. A pivotable locking unit (20) is provided in an inoperative releasing position (21) such that the handle part is actuated. The locking unit arrives from two directions into two operative locking positions in case of crash such that the locking unit locks the handle part in the locking positions under interconnection of locking levers (40). One of the directions is provided opposite to the other direction, where the locking levers are guided in a type of a guide rail (41).

Description

The invention relates to an outside door handle, in particular for vehicles specified in the preamble of claim 1. Art. Such outside door handles find a variety of uses. In the event of a crash, in particular with a strong side impact, it is necessary to prevent the handles of the vehicle doors from pivoting outwards as a result of the released forces and thus opening the vehicle doors. As a result, there would be a risk that the vehicle occupants or objects located in the vehicle will be ejected from the vehicle. In the prior art, therefore, pivotable locking members are proposed, which are deflected due to the inertia of their mass, before it comes to a deflection of the handle and then block an effective operation of the handle, thus avoiding unwanted opening of the vehicle doors.

Such a mass barrier describes, for example, the EP 1 050 640 A2 , Here, an outside door handle for vehicles is described, which has a pendulum-like locking member. In the event of a side impact this locking member is deflected, thereby preventing effective operation of the handle. A disadvantage of this Arrangement is, however, that for the various doors in the vehicle, such as driver and passenger door, various devices must be provided because the blocking of the movement of the outside door handle takes place only in one direction. In addition, the locking member can only prevent unintentional opening of the door in accidents with substantially the same Crashrichtung. If the crash occurs from a direction opposite to the optimum direction to which the device has been designed, inadvertent opening of the door, for example due to the vibration of the handle caused by the crash, can not be prevented.

A similar problem arises also in the case of DE 199 29 022 A1 described outside door handle. Again, a pivotable locking member is provided, which is deflected in the event of a crash and then prevents unintentional actuation of the handle. Again, a separate device must be provided for each side of the vehicle. The inadvertent operation of the handle by a crash, from a direction opposite to the optimal crash angle direction, for example, caused by the crash vibrations, does not prevent the locking member.

The object of the invention is therefore to provide an outside door handle of the type specified, which can be used on all doors of the vehicle and which prevents accidental opening of the vehicle door by a crash from different directions. This object is solved by the characterizing features of claim 1, which has the following special significance.

The locking member has two locking positions. In a crash from a first direction, the locking member then passes through the deflection caused by the crash due to the inertia of its mass in a first locking position. However, if a crash occurs from a second direction, which is at least partially opposite to the first crash direction approximately, the locking member is in another Directed deflected and thus enters a second locked position. This has the advantage that unintentional opening of the door is avoided, regardless of the direction from which the crash occurs. Inadvertent actuation of the handle and an associated opening of the door by the vibrations caused by the impact of the crash are prevented. In addition, it is possible to provide an outside door handle, which can be mounted on all doors, in particular on both sides of the vehicle and which nevertheless meets the requirements for crash safety. This is cheaper to manufacture and also saves on warehousing costs. The locking member locks in the present invention, the handle Zwischenschaltun a blocking lever. This is guided in a slotted guide and moved in the normal operation of the handle. In the event of a crash, however, this movement of the blocking lever is prevented by the locking member, whereby the handle can not be moved and the door does not open unintentionally. The interposition of the blocking lever is a good point of attack for the locking member in its locked position. The link guide ensures a simple and error-prone actuation and movement of the blocking lever.

It is particularly advantageous if it is provided that in the normal operation of the handle, the locking member is moved to a small extent. Since the locking member is naturally rarely used, it could otherwise happen that this gets stuck or jammed over time or that the surfaces corrode. In such a case, a secure operation of the locking member is no longer guaranteed in a then occurring crash case. Due to the comparatively frequent easy operation of the locking member of this setting is avoided. The locking member is thus operational over the entire life of the vehicle.

The blocking lever is connected in a preferred embodiment with an element which is also moved in the operation of the handle, a so-called Loselement. It is particularly favorable for fixing the Blocking lever that Loselement to use, which also passes on the movement of the handle to the lock and thereby enabling the operation of the handle opening the door. The passing of the movement to the castle is often done by means of a Bowden cable or with the help of a rod. However, it is also possible to provide one or more mass balance weights, which provide in the event of a crash for mass balance. Since the mass weights are usually elements that are moved along with the actuation of the handle, they also offer themselves as a loose element to which the blocking lever can be fastened.

In contrast, the locking member should be arranged on a fixed element, which does not move when the handle is operated. Here, for example, offer a bearing bracket or a handle support. These components are usually present in an outside door handle, as they serve to secure the door handle in the door and store.

In a preferred embodiment, the locking member is spring-loaded, wherein the spring load ensures that the locking member normally remains in its release position. This avoids, on the one hand, that the locking member is deflected by normal movements of the vehicle, for example when driving around a curve, from its release position in one of its locking positions and as an actuation of the handle and thus opening the door is no longer possible. It is also important that after a successful crash outside people can open the vehicle door, for example, to free injured vehicle occupants or children from the vehicle. Therefore, the spring load also conveniently ensures that after the crash and after the decay of the vibrations caused by this crash, the locking member is transferred back to its release position, so that the doors can be opened.

It is recommended that two projections are provided on the locking member, wherein each one of these projections in one of the two locking positions with a Counter projection occurs in operative connection. In this way, it is possible to prevent the locking member from being deflected too far in the event of a crash, and thus the undesired actuation of the handle is not avoided. The projections and counter projections may be configured differently, as will be shown later.

Further embodiments and advantages of the invention will become apparent from the following description, the subclaims and the drawings. In the drawings, the subject invention is shown in three embodiments.

Fig. 1 shows the outside door handle according to the invention with the handle 10. A mass balance weight 12 is provided and also serves as a Loselement 11. At mass balance weight 12 of the blocking lever 40 is rotatably articulated. The other side of the blocking lever 40 is located in a mounted on the bearing bracket 14 slotted guide 41. Also arranged on the bearing bracket 14 is the locking member 20, which is in its release position 21. Below the locking member 20, the spring 27 is arranged, which has the tendency to keep the locking member 20 in its release 21. The spring 27 is designed so that it counteracts deflections of the locking member 20 in both directions.

This is something more detailed Fig. 2 to recognize. The locking member 20 has two stops 28.1 and 28.2. In each of its locking positions 22.1, 22.2, the locking member 20 enters with one of its stops 28.1, 28.2 with a counter-stop 43 in operative connection, which will be shown in more detail later. The locking member 20 itself is approximately Y-shaped 50. The stops 28.1, 28.2 are arranged at the ends 52 of the two Y-legs 51.

Also 3 and 4 again show the locking member 20 in its release position 21. Since in the illustration in Fig. 4 the covers were removed, it can be seen clearly how the blocking lever 40, which is moved in a normal operation of the handle 10, abuts the locking member 20, in particular to the ends 52 of the Y-leg 51 and thus causes the slight movement of the locking member 20 Protecting this from jamming.

In the FIGS. 5 and 6 the locking member 20 is shown in its locking positions 22.1, 22.2. Likewise, by way of example, the direction 30.1, 30.2 of a crash which has led to the deflection of the blocking member 20 and thus to the illustrated blocking position 22.1, 22.2 is shown. Of course, the crash does not have to be from exactly the direction shown to result in the result shown. It is quite sufficient if at least a part of the direction of movement of the crash points in the illustrated direction 30.1, 30.2.

It turns out that in each of the locking positions 22.1, 22.2 one of the stops 28.1, 28.2 of the locking member 20 is in operative connection with a counter-abutment 43 on the blocking lever 40. In the illustrated embodiment, there is only one counter-stop 43 for both stops 28.1, 28.2. It can of course also only one stop 28.1, 28.2 and / or two counterstops 43 give, depending on the embodiment of the invention.

Also, one recognizes the recess 24 on the locking member 20 and the pin 16 which is arranged on the bearing bracket 14. The sides 25 of the recess 24 form projections 23.1, 23.2, which come into operative connection with the counter-projections 15.1, 15.2 formed by the pin 16 in the corresponding blocking position 22.1, 22.2. This prevents that caused by the crash deflection of the locking member 20 this is deflected too far, so that the stops 28.1, 28.2 can no longer interact with the counter-stop 43 on the blocking lever 40 in operative connection. Of course, it is equally possible to provide the recess 24 on the bearing bracket 14, while the locking member 20 has a pin 16.

In addition, the function of the stopper 42 is clearly visible. Characterized in that the blocking lever 40 is rotatably mounted on the Loselement 11 and is guided on the fixed element 13 in a link 41, the stopper 42 additionally ensures that the blocking lever 40 between the stop 28.1, 28.2 of the locking member 20 and the stopper 42 is wedged , so that a movement of the blocking lever 40 and thus also the handle 10 in the event of a crash is no longer possible. The forces acting on the handle 10 from the crash forces are thus absorbed by the bearing 44 of the locking lever 40 on the Loselement 11 and the stopper 42 with the participation of the locking member 20. Of course, embodiments without stoppers 42 are possible. There, the forces caused by the crash forces from the sliding block 45 of the slotted guide 41 and the bearing 44 of the locking lever 40 are then added.

This is also from the FIGS. 7 and 8 recognizable, in which also the locking member 20 is shown in its two locking positions 22.1, 22.2. The only difference to the embodiment, which in the FIGS. 5 and 6 has been shown, is that the projections 23.1, 23.2, which is too far deflection of the locking member 20th prevent be formed by the flanks 26 of the locking member 20. In addition, lugs 17 are still provided, which form the mating counter-projections 15.1, 15.2. The interaction of the projections 23.1, 23.2 and the counter-projections 15.1, 15.2 is from the FIGS. 7 and 8 clearly recognizable.

The FIGS. 9a to 14 show a third preferred embodiment of the invention. In the Fig. 9a and 9b one recognizes the locking member 20, which is in its release position 21. In this state, the blocking lever 40 is freely movable in its slotted guide 41. The movement of the blocking lever 40 is purely translational here.

The handle 10, not shown here is in the in the Fig. 9a and 9b shown release position 21 is not actuated. The blocking lever 40 projects with its end 47 and in particular with the attached thereto cam 46 in a recess 24 between the legs 51 of the Y-shaped 50 locking member 20. In this position, the cam 46 is aligned with the opening 29 of the recess 24 on the locking member 20th and the stops 28.1, 28.2 are provided in this recess 24.

If now the handle 10 is actuated, the result is in the 10a and 10b illustrated situation. The end 47 of the blocking lever 40 with the cam 46 arranged thereon has been pulled out of the recess 24 of the blocking member 20 through the opening 29. Opening the vehicle door is possible.

The first and second barrier layers 22.1, 22.2 are in the Fig. 12a and 12b or 11 a and 11 b shown. In this position, the arranged at the end 47 of the blocking lever 40 cam 46 is no longer aligned with the opening 29 of the recess 24. Rather, the cam 46 is trapped in the recess 24. The sides 25 of the recess 24 serve both as projections 23.1, 23.2 and as stops 28.1, 28.2. The counter-projections 15.1, 15.2 are realized by the cam 46 of the blocking lever 40. In this embodiment, there are also two Counter stops 43.1, 43.2 provided, which are also arranged on the cam 46.

Unintentional movement of the handle 10 by the vibration caused by the crash is not possible in the locking positions 22.1, 22.2, since the movement of the blocking lever 40 is blocked by the locking member 20, namely the fact that the cam 46 is caught in the recess 24.

Finally, it is still on the FIGS. 13 and 14 directed. These again give an overview of the arrangement of the most important components of the third embodiment; especially in Fig. 14 the interaction of locking member 20, blocking lever 40 and mass balance weight 12 is clear. It is thus clearly evident that unintentional and accidental actuation of the handle 10 is not possible in the first blocking position 22.1 shown there.

One of the particular advantages of this embodiment is that no different components are required for the stops 28.1, 28.2 and the projections 23.1, 23.2. The same applies to the counter-stops 43.1, 43.2 and counter-projections 15.1, 15.2. As a result, the outside door handle according to the invention according to the third embodiment is particularly simple and inexpensive to manufacture.

Finally, it should be pointed out that the embodiments shown here are merely exemplary implementations of the invention. This is not limited to this. Rather, multiple modifications and variations are possible. For example, the locking member may have only one Y-leg or configured differently. It is also possible that the locking member has only a single locking position or locks only in a Crashrichtung.
