Definitions
- the invention relates to a Bowden cable with a Bowden cable having a sheath and an inner cable on which a means is fixed, which cooperates with a movement of the Bowden cable with a mechanism having at least one lever which is actuated by the means with an end stop which limits the movement of the inner cable in the pulling direction and with a compensating means which is elastically deformable when the inner cable is subjected to a tensile force beyond the end stop.
- the present invention relates to a seat adjuster of a motor vehicle with a rail release and a memory function, the rail release by a movably mounted movement means actuated and the memory function is triggered by a movably mounted release means and the actuating means and the triggering means of an activation are drivable.
- Bowden cables are often used, for example in the automotive industry, to make adjustment to adjustable device, such as flaps or end / Verschhegelungsmechanismen. Often the Bowden cables do not only one but several functions. Since it is comparatively expensive and therefore undesirable to adjust the Werweg of Bowden cables very accurately, especially because they are often operated manually, it is important that the Bowden cable, if he continues to be charged beyond a certain predetermined limit, the case, the surround the inner cable, not damaged.
- a motor vehicle is described with a seat frame.
- the seat frame has a backrest, which is pivotally mounted on the seat frame and can be folded forward in the direction of the seat surface of the seat frame.
- the seat has a longitudinal guide with which the seat frame for adjusting the longitudinal position in the seat direction is movable.
- a locking device With a locking device, the seat frame is locked in a previously set seat longitudinal position.
- a coupling mechanism which acts on the locking device, unlocks this locking device when the backrest in the direction of the seat is folded forward.
- the seat frame is traceable in a movement in the rail longitudinal direction in a seat longitudinal position defined as a memory position.
- the locking device and the memory device are activated by a Bowden cable, which is connected to the backrest. Since these Bowden cables always have tolerances, it often happens that beyond the Enthegelungs- or memory position train from the Bowden cable is exerted on the activation elements. This phenomenon is referred to in motor vehicle technology as "overstroke.” The overstroke often leads to premature failure of the unlocking device or the memory device or to damage to the Bowden cable.
- the compensating means prevents damage to the sheath and / or the mechanisms actuated by the Bowden cable when the inner cable is loaded beyond a certain limit.
- the Bowden cable according to the invention can operate several means, such as levers, simultaneously or sequentially.
- the Bowden cable comprises a means, such as a sliding block, which cooperates with a mechanism having at least one lever operable by the means.
- the Bowden cable actuation has a further mechanism, which is for example in engagement with the end of the Bowden cable.
- This mechanism preferably has at least one further lever, with which a further function, such as unlocking or locking, can be performed.
- This lever also preferably cooperates with an end stop, which prevents further movement of the Bowden cable in the pulling direction.
- the Bowden cable actuation according to the invention can be part of any desired mechanics. Preferably, however, it is part of a motor vehicle, most preferably part of a seat. Most preferably, the Bowden cable according to the invention is part of the easy-entry mechanism of a car seat, with the entry into the rows of seats behind the driver or front passenger seat is facilitated.
- Another object of the present invention is a seat adjuster of a motor vehicle seat according to claim 9.
- the seat adjuster according to the invention is simple and inexpensive to manufacture and assemble, since much larger tolerances in the Bowden cable adjustment are possible than was previously the case.
- the seat adjuster according to the invention has a rail unlocking.
- This rail unlocking causes the lower and the upper rail, which are mounted relative to each other to be able to move the vehicle seat in the longitudinal direction in a very specific position in which the motor vehicle seat is then locked to lock or unlock.
- the word rail release is used equally for unlocking and locking.
- the rail release is also required in the so-called easy-entry function, in which by the folding forward of the backrest, the boarding of the passenger or the insertion of an object in the rear of the vehicle to be facilitated. By folding the backrest, the rail release is actuated, so that the upper rail can slide freely on the lower rail forward, which increases the space behind the respective motor vehicle seat for boarding.
- the seat adjuster according to the invention has a memory function according to the invention.
- Such memory functions are known from the prior art and have the task that the vehicle seat, after it has been brought into the easy-entry position, then again with unlocked locking device can be moved backwards until it by means of memory Device is automatically stopped in a seat position defined as a memory position.
- the seat is after pushing back and stopping the memory position automatically in a seat longitudinal position in which a passenger can sit on the vehicle seat.
- the seat is thus automatically stopped by means of the memory device during its backward movement in a seat longitudinal position defined as a memory position.
- Both the rail unlocking and the memory function are driven by an activation, which in turn is connected to a Bowden cable, whose one end cooperates with the activation and whose other end cooperates with the backrest of the motor vehicle.
- the activation comprises an activating agent.
- this activating means actuates a triggering means, for example a lever, which actuates the memory function.
- the activating means preferably has a cam track which moves or fixes the triggering means in certain positions.
- an actuating means for example a lever, driven, which in turn actuates the rail unlocking, d. H. the lower rail with the upper rail locked or unlocked.
- the actuating means is a lever which is rotatably mounted.
- the activation can be actuated with the Bowden cable actuation according to the invention.
- the activation comprises a connecting means which is connected to the Bowden cable.
- This connecting means is further connected via a spring element angularly variable with the activating means, wherein the force which is required to activate the actuating means or the triggering means, is smaller than the spring force of the spring element.
- the spring element may be any spring element familiar to the person skilled in the art.
- the spring element is a helical spring, one end of which cooperates with the activating means and the other end with the connecting means.
- this spring element is biased to avoid, for example, rattling noises in the activation area.
- the activation comprises a stop which limits an angular change between the activating means and the connecting means in one direction of rotation.
- This embodiment of the present invention is particularly needed to keep the spring element under a constant bias.
- the activation means When activating the Bowden cable, the activation means preferably transfers the release means into an actuation position and holds it there.
- the activating means transfers the actuating means to an actuating position.
- the actuation position is reached before the actuation position.
- the position of the connecting means changes to the position of the activating agent.
- the pull force of the Bowden cable exceeds the spring force of the spring element in an overstroke of the Bowden cable.
- FIG. 1a shows the Bowden cable actuation according to the invention, in which the Bowden cable is not actuated
- Figure 1 b shows the Bowden cable actuator according to Figure 1a, in which the lever for the easy-entry mechanism is actuated and
- Figure 1c shows the Bowden cable according to the invention according to the figures 1a and 1b, in which the Bowden cable is completely actuated.
- FIG. 2 shows the seat adjuster according to the invention in the design position
- FIG. 3 shows the seat adjuster according to the invention with activated memory function
- FIG. 4 shows the seat adjuster according to the invention with activated memory function and released rail lock
- Figure 5 shows the seat adjuster according to the invention in overstroke
- FIG. 6 shows an enlargement of the activation in the overstroke according to FIG. 5.
- FIG. 1a shows the Bowden cable actuation 1 according to the invention, which has two adjustment mechanisms 4, 11.
- the Bowden cable 2 consists of a shell 8 and an inner cable 9.
- a sliding block 3 is fixed, which, as soon as the inner cable 9 is pulled in the direction indicated by the arrow 12 pulling the lever 5 down.
- At its right end of the Bowden cable 9 is slidably disposed on the adjusting mechanism 1 1.
- Figure 1 b shows the Bowden cable actuation according to Figure 1a, wherein the sliding block 3 has already been pulled a piece to the left while the lever 5 to a has pushed down some distance.
- the lever 5 thereby actuates the easy-entry mechanism, in particular the storage function, by which it is ensured that the car seat, in particular the seat rail, is folded back into the same position after folding in or advancing (see FIG. Since the right end of the inner cable is slidably mounted in the adjusting mechanism 1 1, the lever 10 of the adjusting mechanism 1 1 remains unaktuiert for the time being.
- Figure 1c shows the Bowden cable actuation, in which the Bowdenzugweg is fully actuated.
- the sliding block 3 has slipped a little further to the left and has pressed the lever 5 even further down. This change in the position of the lever 5 no further function is activated.
- the person skilled in the art recognizes that the comparatively long sliding path of the sliding block 3 allows the point in time at which the easy-entry mechanism is actuated to be adjustable, in particular also relative to the actuation of the further adjusting mechanism 1.
- the inner cable 9 has the lever 10 against pivoted clockwise down until it is in engagement with the end stop 6. By pivoting the lever 10, the seat rail is unlocked and can be moved as shown in Figure 1 c to the right.
- the inner cable 9 can not move further. If a further tensile force is exerted in the direction of the arrow 12 on the inner cable, the casing 8 presses on the slide bearing 14 of the spring 7 and compresses it, so that the casing is not damaged.
- FIG. 2 shows the seat adjuster 1 ' according to the invention, which has an upper rail O and a lower rail U.
- the bottom rail U is firmly connected to the body.
- the upper rail O is slidably disposed on the lower rail and can be fixed in a specific position by the rail lock on the lower rail.
- the Schienenent- or -Lerriegelung 4 ' is activated by the actuating lever 9 ' , which is rotatably mounted about the pivot 15 ' .
- the seat adjuster according to the invention has a memory function 2 ' , which causes the seat to be automatically traceable to a very specific position after it has been moved to an easy-entry position. This memory function is actuated by the release lever 7 ' .
- Both the actuating lever 9 ' and the trigger lever 7 ' are driven by the activation 1 1 ' , which is essentially an activating means 8, a connecting means 5 ' and a coil spring 10 ' .
- Both the activating means 8 ' and the connecting means 5 ' are rotatably mounted about the axis 16 ' and interconnected by means of the spiral spring 10 ' , one end of the spiral spring cooperating with the connecting means 5 ' and one end with the activating means 8 ' .
- Spiral spring 10 ' causes the activating means 8 ' and the connecting means 5 'are angularly connected to each other.
- the coil spring is biased to urge the connecting means 5 ' against the stop 12 ' located on the activating means 8 ' .
- the Bowden cable 3 ' is connected to the connecting means 5 ' .
- FIG. 2 shows the so-called design or operating position. In this position, the upper and lower rails are locked together and the memory function is deactivated.
- FIG. 3 shows the state in which the memory function is activated.
- the coil spring 10 ' and the connecting piece 5 ' are omitted in this illustration.
- a tensile force is exerted on the Bowden cable 3 ' , which is transmitted to the connecting means 5 ' .
- the coil spring 10 ' By the coil spring 10 ' , the tensile force is transmitted to the activating means 8 ' and there induces a torque which causes the activating means 8 ' to rotate counterclockwise.
- the activation means 8 ' has a cam track 6 ' , which cooperates with the triggering means 7 ' and triggers the memory function by pressing the trigger lever 7 ' down into the operating position and holds in this position.
- FIG. 4 shows the unlocking of the rail lock 4 ' .
- the activating means 8 is rotated further counterclockwise and presses the operating lever 9 ' , which is connected to the rail unlocking 4 ' , down into the operating position 14 ' and thus unlocks the upper rail and the lower rail, so that the upper rail freely movable forward to the easy-entry position can be moved. Also in this position of the activating means 8 'of the trigger lever 7 ' is held in the operating position 13 ' .
- FIG. 5 shows the situation of the so-called overtravel. If the rear seat is pressed even further in the direction of the seat, another train is exerted on the Bowden cable, although both the actuating lever 9 ' and the triggering means 7 ' are already in their end positions. In this situation, the tensile force of the Bowden cable 3 'is greater than the spring force of the coil spring 10 ' , so that the connecting means 5 'is moved counterclockwise away from the stop 12 ' . However, a change in the position of the activating means 8 ' does not occur, so that unnecessarily high forces are exerted on the actuating lever 9 ' or the triggering means 7 ' .
- FIG 6 shows an enlarged view of the activation according to FIG 5. It is clearly seen that when excess stroke, the connecting means 9 'of the stopper 12', which is arranged on the activation means 8 ', is moved away and thus compensates for the overtravel.
